Compromised Credential Statistics 2026: Costs & Defenses

• Average breach cost: Globally, the average cost of a data breach declined to $4.44 million in 2025, down from $4.88M in 2024, due to faster AI driven detection and response. IBM's 2026 report then put it at a record $4.99 million.
• Regional extremes: The United States saw the highest costs: an average $10.22 million per breach in 2025, a record, and $11.5 million in IBM's 2026 report. For UK organizations reducing credential-breach risk, advanced economies such as the UK and Germany still face material breach-cost exposure, averaging $4.14M and $4.03M respectively in 2025.
• Healthcare remains costliest: Healthcare breaches averaged $7.42M in 2025 and $6.64M in 2026, still the highest of any industry, driven by the high value of patient data and regulatory fines. Financial services averaged $6.08M in IBM's 2024 data and $5.56M in 2025, while retail was lower at $3.54M.
• Stolen credentials prevalence: In Verizon's 2025 DBIR, 22% of breaches began with credential abuse, the most common initial access vector, ahead of vulnerability exploitation (20%) and phishing (16%). In the 2026 DBIR, exploitation rose to 31% and credential abuse fell to 13% as a first step, but stolen credentials still appeared at some stage of 39% of breaches.
• Cost per credential breach: Breaches that started with stolen credentials averaged $4.81M in IBM's 2024 report and $4.67M in 2025. These attacks are stealthy and damaging, often involving deep persistence.
• Detection dwell time: In IBM's 2024 report, credential-based breaches took the longest of any vector to identify and contain (292 days); in its 2025 report they took 246 days, slightly above the 241-day average for all breaches. Longer dwell correlates with higher costs: breaches with lifecycles over 200 days cost $5.01M in 2025, versus $3.87M for faster ones. IBM's 2026 report puts the all-breach average at 247 days, with breaches over 200 days at $5.65M versus $4.32M for faster ones.
• AI assisted attacks: Modern breaches increasingly involve AI. In IBM's 2025 study, 16% of breaches involved attackers using AI (e.g. AI-generated phishing and deepfakes), and shadow AI (employees using unauthorized AI tools) added about $670K to breach costs. IBM's 2026 study found one in four malicious breaches was AI-enabled. At the same time, defenders using AI and automation extensively cut average breach costs by about $1.9M in 2025 and $1.93M in 2026.
• Mass credential leaks: The underground credential supply has exploded. In November 2025, Have I Been Pwned loaded credential stuffing lists gathered by threat intelligence firm Synthient: about 2 billion unique email addresses and 1.3 billion unique passwords. Much of that supply, including session tokens harvested by infostealer malware, is bought and sold on log markets like Russian Market.
• Initial Access Brokers: Rapid7's 2025 report (H2 2024 listings on three forums) put the average price for corporate network access just over $2,700, with nearly 40% of offerings priced between $500 and $1,000 and 71% offering privileged access. Its March 2026 update, covering 2025 listings on five forums, reported an average base price of $113,275, driven largely by high-priced DarkForums listings, so prices now vary widely by forum and target.
• Phishing resistance: The industry is moving toward phishing resistant authentication. For example, Google reported in May 2024 that 400+ million accounts were using passkeys (FIDO2/WebAuthn), which cannot be phished or reused across domains. Because passkeys are bound to the legitimate site, they remove the reusable secret that phishing and credential stuffing depend on.

Each of these insights is drawn from recent breach reports by IBM, Verizon DBIR, Rapid7, etc., and reflects the emerging identity siege trend: adversaries rely heavily on credentials alongside technical exploits, driving costs and risks higher.

Compromised credentials (user names, passwords, tokens, or certificates stolen or misused by attackers) have emerged as a leading driver of data breaches. In a world where organizations invest heavily in network defenses, criminals increasingly walk through the front door with valid login data. 2024–2026 statistics paint a clear picture: breaches rooted in stolen credentials are among the most frequent, costly and longest lasting. For example, Verizon’s 2025 DBIR found 22% of breaches began with stolen credentials, higher than any other category, and IBM's 2024 report found these incidents took 292 days to identify and contain on average. Meanwhile, the global average breach cost was $4.44M in 2025 and a record $4.99M in 2026, and identity based intrusions remain a large part of that bill (see our data breach statistics).

Why do these stats matter? First, they highlight that the weakest link in cybersecurity is often human authentication. Credential breaches enable wide lateral movement and ransomware with minimal technical exploits. Second, the numbers illustrate how attackers exploit systemic weaknesses, password reuse, lack of MFA, shadow credentials at scale. Furthermore, organizations frequently overlook how internal collaboration can lead to leaks, necessitating a shift toward secure password sharing to eliminate plaintext exchanges. Third, understanding these metrics is crucial for leaders: it informs investment in defensive measures like passwordless authentication, identity threat detection, and secret management. This report dives into the data, showing how the Identity Siege has reshaped risk in 2025 and 2026.

What Are Compromised Credential Statistics?

Compromised credentials statistics refers to data and metrics related to security incidents where attackers gained access using stolen or leaked login information. This includes breaches initiated by credential stuffing, phishing of passwords, purchase of hacked accounts, or malware that steals sessions. Think of it as the digital equivalent of broken keys or forged passports: attackers get valid credentials and quietly move inside. Some stolen passwords are captured as people type them, as our guide to keyloggers explains.

These statistics typically cover: the share of breaches caused by credential compromises, the cost and damage of those breaches, the time attackers remain undetected with valid credentials, and the volume of leaked passwords circulating on illicit markets. For example, IBM’s breach report defines compromised credentials as an initial access vector and measures how often it occurs and what it costs. In practice, if a user’s password from a previous breach is reused at a corporate account, that incident falls under these stats.

A helpful analogy: if perimeter defenses are a castle wall, compromised credentials are skeleton keys the attackers have made. Statistics in this area help organizations understand how often those keys exist and what happens when they’re used.

Global Overview 2024–2026

• Cost trends: The global average breach cost eased to $4.44M in 2025 from $4.88M in 2024, thanks largely to faster AI assisted detection, then rose to a record $4.99M in IBM's 2026 report. U.S. companies saw a record $10.22M in 2025 and $11.5M in 2026. This divergence reflects heavier regulatory fines and expensive breach handling in the U.S.
• Industry: Healthcare remains far costlier than other sectors. The average health sector breach fell to $7.42M in 2025 from $9.77M, and to $6.64M in 2026, but is still the highest of any industry. Finance averaged $6.08M in IBM's 2024 report and $5.56M in 2025. Retail, by comparison, averaged $3.54M in 2025.
• Attack vectors: IBM’s 2024 data showed compromised credentials as the top initial vector at 16% of breaches; in its 2025 data phishing took the top spot at 16%. Verizon's 2025 DBIR put credential abuse first at 22%, while its 2026 DBIR shows vulnerability exploitation overtaking it. Credentials remain central even when they are not the first step: the 2026 DBIR finds credential abuse at some stage of 39% of breaches (see our data breach statistics).

These overview stats underscore a critical shift: breaches are becoming more identity driven, and even as AI and automation help reduce some costs, leaked credentials are causing longer, deeper compromises.

Cost Breakdown

Understanding breach costs involves many components: forensic response, legal fees, remediation, and lost business. IBM’s Cost of a Data Breach Report 2025 (summarized in our data breach statistics) shows several trends:

• Cost per record: On average, each record (e.g., a file with personal data) stolen in a breach costs about $160 to the victim organization, IBM's 2025 figure for customer personal data. Highly sensitive data like IP or medical records drive costs above this baseline (see our data breach statistics).
• Detection & Response: Organizations using AI and automated tools benefit greatly. For example, companies employing security automation reported $1.9M less cost per breach, largely by cutting the breach lifecycle by ~80 days (IBM 2025); IBM's 2026 report puts the saving at $1.93M.
• Stage of discovery: Incidents disclosed by the attacker e.g. via ransomware note averaged $5.53M in 2024, versus $4.55M when found internally.
• Shadow data premium: When attackers accessed unmonitored data stores, cloud backups, file shares, breach costs were about 16% higher in IBM's 2024 report. This shadow data often lies outside normal security controls, so stolen credentials giving access can magnify damage.

Key takeaways: rapid detection saves millions, as breaches resolved under 200 days cost ~$1.14M less. Health care breaches still incur top dollar: healthcare breaches averaged $7.42M in 2025, driven by costly HIPAA fines and urgent downtime. In all sectors, lost business downtime, churn and breach response forensics, legal are now larger cost drivers than ransom payouts.

Attack Vector Distribution

Attackers still rely on old school methods though wrapped in modern tech. Below are the most common initial access routes in breaches:

• Stolen credentials 22%: The most common vector in Verizon's 2025 DBIR, before exploitation overtook it in 2026. Attackers use leaked passwords, social engineered credentials, or infostealer logs to log in as legit users. IBM reports these breaches averaged $4.81M each in 2024 and $4.67M in 2025.
• Phishing ~16%: Carefully crafted phishing emails remain ubiquitous, and phishing was the most common initial vector in IBM's 2025 data. Victims unwittingly hand over passwords or MFA tokens. IBM put the average cost of a phishing breach at $4.88M in 2024 and $4.8M in 2025, rivaling credential theft. Notably, many phishing kits now target MFA codes (AiTM attacks).
• Exploited Vulnerabilities 20%: In Verizon's 2025 DBIR, unpatched flaws in VPNs, web apps, etc. were the initial entry in 20% of breaches, rising to 31% in the 2026 DBIR. These often serve merely to retrieve credentials, e.g. memory dumping on Citrix devices, and tend to enable widespread access and data exfiltration.
• Supply Chain 15%: Attacks via compromised vendors or apps have surged. IBM’s 2025 report shows supply chain compromise as the second most common vector at 15% of breaches, costing $4.91M on average, and Verizon's 2026 DBIR found third-party involvement in 48% of breaches. For example, the 2024 Change Healthcare attack hit a claims processor serving much of the U.S. healthcare system (see our data breach statistics).
• Insider 7%: While less frequent, malicious insiders caused the highest individual costs in IBM's 2024 report at $4.99M on average ($4.92M in 2025). These involve employees or contractors misusing their credentials.

In summary, vulnerability exploitation, credential abuse and phishing are the leading entry points. The availability of massive credential dumps means attackers often bypass sophisticated firewalls. Verizon's 2025 DBIR found that about 88% of breaches in its Basic Web Application Attacks pattern involved stolen creds. Once inside, adversaries typically escalate via credential theft, making the initial vector only the first step.

Industry Breakdown

Different sectors see different breach patterns and costs:

• Healthcare: Far and away the most expensive. In 2025 the average healthcare breach cost $7.42M, and $6.64M in IBM's 2026 report. High cost drivers include protected health information (very valuable on black markets) and the critical need to keep systems online. Breaches take longest to resolve in healthcare: IBM found ~279 days to identify/contain. This sector also sees frequent use of stolen credentials to deploy ransomware, as in the 2024 Change Healthcare case.
• Financial Services: Among the costliest sectors: $6.08M per breach in IBM's 2024 report, $5.56M in 2025 and about $6.3M in 2026. Banks and fintech firms fight sophisticated credential stuffing and automation attacks. They frequently recover faster due to mature detection, but still face attacks aiming to directly siphon funds or launder money. In Verizon's 2025 DBIR, 90% of financial sector breaches were financially motivated.
• Technology: Average breach cost was $4.79M in IBM's 2025 report. Tech companies hold valuable IP and often face supply chain risks. Breaches here (e.g., at software providers) can cascade to many customers.
• Manufacturing: A rising target, especially in APAC, where downtime of assembly lines makes every hour of disruption expensive. Forescout tracked a 71% increase in threat actors targeting manufacturing. In Sophos' 2025 manufacturing survey, exploited vulnerabilities were the root cause of 32% of ransomware attacks on manufacturers, and compromised credentials of 20%, often used to reach remote access and OT systems.
• Retail: Lower average costs ~$3.54M due to consumer scale data, but high incident frequency especially around holiday seasons. Attackers increasingly target customer loyalty and payment accounts with credential stuffing. Disclosed ransomware attacks on retailers rose 58% from Q1 to Q2 2025. Notably, a credential stuffing attack hit VF Corp’s The North Face in April 2025, affecting 2,861 customer accounts, illustrating how retail sites are exploited via reused logins.
• Government & Public Sector: While specific cost figures vary, governments face large scale espionage style breaches. Many nation state attacks begin with spear phishing or supply chain compromises. Classically, breaches in government are slower to detect due to siloed systems. IBM's 2025 study put the public sector average at $2.86M, below the cross-industry average.

Overall, industries holding highly sensitive or critical data health and finance see the highest breach costs, and healthcare the longest exposure times. Retail and consumer sectors have more frequent breaches but lower per incident cost. Attack vectors also vary: healthcare heavily phished, finance hammered by credential stuffing, manufacturing often hit by OT exploits plus lateral creds.

Regional Breakdown

Breach costs and threats also differ by geography:

• For U.S. organizations reducing compromised-credential breach exposure, the U.S. leads global breach costs at $10.22M per incident in 2025 and $11.5M in 2026, making identity validation, access-path testing, and credential hygiene critical risk controls. Factors include strict regulations, breach-notification laws in all 50 states, SEC cybersecurity rules, active litigation, and high value target profiles. The U.S. also accounted for about a quarter of customers affected by cyberattacks in Microsoft's Digital Defense Report (24.8% in the 2025 edition; 25.5% in the 2026 edition). Canada’s costs ($4.84M in 2025) are rising.
• Europe: Western European costs are lower: the UK averaged $4.14M and Germany $4.03M in 2025, both down from 2024. Mature GDPR compliance means heavy fines for negligence, so breaches carry steep legal and regulatory costs. Phishing was the leading intrusion vector in about 60% of EU incidents in ENISA's 2025 analysis.
• Middle East & Africa: The Middle East reported a $7.29M average in 2025, the second highest globally, and $8.00M in IBM's 2026 report. Geopolitical tensions mean many attacks are destructive, and the region has seen numerous wiper and malware campaigns, often starting with stolen admin credentials.
• Asia Pacific: Asia was the most attacked region in IBM X-Force's 2024 data, with 34% of incidents; in the 2026 index (2025 data), North America became the most attacked region at 29% and Asia-Pacific fell to 27%. Verizon's 2024 DBIR found credentials were the data compromised in 69% of APAC breaches. Japan’s costs ($3.65M) are moderate, while ASEAN averaged $3.67M in 2025 and $4.12M in 2026, with sharp increases in attacks on supply chain and critical infrastructure targets.
• Latin America: Costs are lower in Brazil ~$1.22M, but breaches are increasingly reported as more companies publish yearly data. Still, cybercrime is rising due to less mature defenses and often inadequate logging.

In summary, while credential threats are global, U.S. and Middle East victims pay the highest price in fines and losses. Regions with strong compliance Europe manage better hygiene and modest costs, whereas APAC and LATAM face growing attack volumes. Attacks often exploit local dynamics such as password reuse and slower MFA adoption.

Major Breaches of 2024–2025

Several high profile incidents illustrate the impact of compromised credentials:

• VF Corporation The North Face April 2025: VF Corp notified customers of a small-scale credential stuffing attack on its North Face online store. Hackers reused usernames/passwords leaked from earlier breaches to log into accounts. According to the company's breach notice, 2,861 accounts were affected, and personal data names, emails, etc. were exfiltrated. This incident underscores how credential reuse in one breach leads to downstream compromises elsewhere.
• Change Healthcare February 2024: In one of the largest healthcare breaches, the ALPHV/BlackCat ransomware group breached UnitedHealth’s Change Healthcare subsidiary. Congressional testimony revealed the entry point: compromised Citrix credentials allowed remote access without MFA to the billing network. BlackCat then deployed ransomware, shutting down hospitals’ billing systems nationwide. This attack, and a reported $22M ransom payment, exemplify how a single stolen credential, in a high value third party system, can cascade into industry wide crises.
• Synthient Credential Stuffing Data (published November 2025): While not a breach of a single company, threat intelligence firm Synthient aggregated credential stuffing lists containing about 2 billion unique email addresses and 1.3 billion unique passwords, compiled from countless past breaches and infostealer logs. Have I Been Pwned loaded the data in November 2025, and Troy Hunt noted 625 million of the passwords had never been seen in HIBP before. Synthient’s work shows how attackers can automate breaches at scale by cycling through these leaked combos.

Each case highlights facets of the credential threat: the North Face incident was driven by reused credentials; Change Healthcare by a targeted steal of corporate creds; Synthient’s database by automated gathering of billions of leaked logins. Together, they illustrate why defenses can’t rely solely on perimeter tools and identity must be secured end to end.

Emerging Trends

Looking ahead, several trends are shaping the credential threat landscape:

• Professionalization of the Underground: The initial access broker IAB market is booming. Dark web forums now offer packaged network access deals. Rapid7’s 2025 report, based on H2 2024 listings on three forums, found the average price for corporate access was just over $2,700, and nearly 40% of offerings were priced between $500 and $1,000. 71% offered not just an entry point but privileged credentials, often Domain Admin. Rapid7's March 2026 update, covering 2025 listings on five forums, reported a much higher average base price of $113,275, driven largely by DarkForums listings, so prices vary widely by forum and target. In effect, ransomware groups no longer need hacking skills; they simply buy ready made access. This commoditization means even small businesses are targets, as their networks are for sale. Security teams must now assume that any exposed entry RDP, VPN accounts could be weaponized almost immediately.
• Infostealer Malware Epidemic: Malware that harvests credentials passwords, cookies, certificates has surged. IBM X Force reports 84% more infostealer delivery via phishing in 2024 than 2023, and early 2025 data suggests a ~180% jump over 2023. Dominant families have included Lumma, Vidar, RedLine and StealC; Lumma remained one of the most active infostealers after its May 2025 takedown, according to several threat-intelligence vendors. These stealers build vast combo lists: Troy Hunt notes we now have billions of stolen passwords and cookies in circulation. This scale fuels credential stuffing attacks: if even 1% of those 2B credentials are valid for some service, attackers automate logins endlessly.
• AI in Attack and Defense: Generative AI is a double edged sword. On offense, AI helps craft highly effective phishing content (fully AI-generated phishing emails got a 54% click rate in a 2024 study) and bypass 2FA via Adversary in the Middle kits like EvilProxy or Tycoon. In IBM's 2025 study, 16% of breaches involved attackers using AI, and IBM's 2026 study found one in four malicious breaches was AI-enabled. Meanwhile, defenders are deploying AI tools for anomaly detection: organizations using AI and automation extensively contained breaches about 80 days faster in IBM's 2025 data (see our data breach statistics). This time advantage can prevent an attacker from achieving deep data exfiltration.
• Leaked Secrets on GitHub: A dangerous trend is accidental leakage of machine credentials (API keys, tokens) in code repositories. Wiz found that 65% of the Forbes AI 50 companies had leaked verified secrets on GitHub, as CSO Online reported. GitGuardian counted 12.8 million new secrets leaked on public GitHub in 2023 and 23.8 million in 2024; its State of Secrets Sprawl 2026 report counted 28.65 million in 2025. These keys often belong to cloud services or databases. Attackers routinely scan GitHub, then use discovered secrets to pivot into corporate networks where the keys may have admin privileges.
• Shift to Secure Authentication Passkeys: In response, industry is embracing passwordless and phishing resistant login methods. By 2024 Google alone had 400+ million accounts using passkeys FIDO2/WebAuthn. Unlike SMS or push MFA, passkeys cannot be intercepted or reused on attacker domains. Organizations adopting FIDO2 drastically cut credential phishing losses. This transition is critical: any move away from static passwords and even OTPs drastically shrinks the credential threat surface.
• Non Human Identities: Finally, machine identities are a growing concern. Cloud applications, microservices, and bots now have far more credentials than humans: CyberArk's 2025 research found machine identities outnumber human ones by 82 to 1, and 42% of them have privileged or sensitive access. Leaked API keys from repos or build systems have led to breaches where attackers impersonate services, e.g. hijacking a SaaS integration. As enterprises deploy more automation, securing service accounts and API tokens becomes as vital as protecting user passwords.

These dark web statistics show the landscape evolving: credentials are sold, stolen, and automated. Defenders must likewise modernize, using AI for detection, eliminating passwords where possible, and inventorying all forms of identity human and machine. The battle has moved beyond code exploits to identity economics.

What These Statistics Mean

The hard data paint an unequivocal picture: identity is the new perimeter. Credentials remain one of the most consequential attack paths. Credential abuse was the top initial access vector in Verizon's 2025 DBIR (22%) and still appears at some stage of 39% of breaches in the 2026 DBIR, even though vulnerability exploitation (31%) is now the most common first step. In IBM's 2025 data, credential-based breaches cost $4.67M and took 246 days to identify and contain, slightly above the $4.44M and 241-day averages. In effect, cybercrime has industrialized identity theft: attackers can buy access from brokers, use automated stealers to hoover up logins, and employ AI to hijack sessions.

For organizations, the implication is stark. Traditional defenses, firewalls, and signature AV are insufficient when adversaries hold valid keys. Security strategy must shift to assume breach and focus on limiting what credentials can do. The statistics show that investment in identity protection and rapid response pays off: AI enabled monitoring shaved ~80 days off average breach detection, saving nearly $2M. Conversely, failure to rotate credentials or enforce MFA leads to drawn out and expensive recoveries.

Ultimately, the math favors attackers: with billions of passwords circulating (Synthient’s 2B alone) and credential abuse as the initial access vector in 22% of breaches in Verizon's 2025 DBIR, adversaries have a huge head start. Without changes, breaches will continue to climb in scope and cost. The data suggest a clear defense imperative: shrink the credential attack surface (e.g., passwordless logins), shorten dwell time (AI triage), and hunt aggressively for leaked secrets. Many breaches will still involve credentials at some stage.

Best Practices for Mitigation

Given the risks, here are recommended strategies to blunt credential based attacks:

• Deploy Phishing Resistant MFA: Move beyond SMS or app codes. Use FIDO2/WebAuthn passkeys or hardware security keys wherever possible. These prevent even sophisticated phish kits AiTM from intercepting logins. Google’s move to passkeys over SMS is a leading example. Our zero trust statistics track phishing-resistant MFA progress in federal agencies.
• Inventory & Secure All Identities: Maintain an up to date inventory of user and machine accounts. Use a password manager and enforce unique, strong passwords. Rotate service account keys regularly and vault them. Scan code repositories and containers for hard coded secrets the 28.65 million secrets leaked on public GitHub in 2025 illustrate the stakes.
• Apply Least Privilege: Limit administrative rights. Rapid7's 2025 report found that 71% of brokered access offerings included privileged access, so ensure that compromise of any single account can’t immediately escalate. Implement just in time privileges and continuous attestation of privileged sessions.
• Monitor and Respond: Use AI/ML based anomaly detection on login behavior and network flows. Security teams using AI and automation found breaches ~80 days faster. Prioritize monitoring for unusual logins, multiple geolocations, odd hours and unusual access to critical data stores.
• Credential Hygiene: Ban password reuse across critical systems. Integrate dark web password watching e.g. a breached password API into login flows block logins using known breached passwords.
• Teams can also use a digital footprint checker to identify whether exposed personal data tied to employee or customer identities is already circulating online
• Incident Preparedness: Assume an intruder with valid creds is already inside. Practice rapid response playbooks so the team can contain an intrusion quickly (see our data breach statistics). Secure backups offline: the new breed of ransomware attacks admin accounts and backups.

By implementing these practices, organizations can start to reverse the trends. A professional red-team engagement can test whether stolen credentials enable privilege escalation, lateral movement, persistence, and data exfiltration before defenders detect and contain the attack. The data is clear: each day saved in breach detection saves millions. Each mitigated credential leak avoids another potentially catastrophic intrusion.

FAQs

• How prevalent are credential related breaches?

Stolen or compromised credentials were the most common initial attack vector in Verizon's 2025 DBIR, at 22% of breaches, ahead of vulnerability exploitation (20%) and phishing (16%). In the 2026 DBIR, exploitation rose to 31% and credential abuse fell to 13% as a first step, but stolen credentials still appeared at some stage of 39% of breaches. In other words, credential abuse remains one of the biggest causes of breaches, even when it is not the first step.

• What is the average cost of a data breach today?

Globally, the average cost of a data breach fell to $4.44 million in 2025, then rose to a record $4.99 million in IBM's 2026 report. Costs vary widely by region and industry: U.S. breaches averaged $10.22M in 2025 and $11.5M in 2026, the highest in the world, while healthcare averaged $7.42M in 2025 and $6.64M in 2026. Shorter breach lifecycles keep costs lower: in 2025, breaches over 200 days cost $5.01M on average, about $1.14M more than faster ones.

• How much damage do breaches involving stolen credentials cause?

Very high damage. IBM’s research shows breaches that started with stolen credentials averaged $4.81M each in 2024 and $4.67M in 2025, comparable to the global average breach cost. More importantly, these breaches usually last longer: IBM cited 292 days to identify and contain them in 2024, the longest of any vector, and 246 days in 2025, leading to deeper data theft and higher cumulative losses in lost business, legal fees, etc.

• What industries are targeted most by credential theft?

All industries face credential threats, but highly lucrative or regulated sectors feel it hardest. Healthcare suffers the highest per incident cost ($7.42M in 2025, $6.64M in 2026) and often long recovery times. Finance and tech firms also see frequent credential attacks because of the direct monetary value of bank accounts, trading systems and IP. Retail companies are targeted too: disclosed ransomware attacks on retailers rose 58% from Q1 to Q2 2025. No sector is immune; any organization with web accessible accounts is a potential target.

• How do attackers typically steal credentials?

The main methods are 

• Phishing: tricking users into entering credentials on fake sites or forms; 16% of breaches started this way in Verizon's 2025 and 2026 DBIRs.
• Malware Infostealers: malicious software that scrapes saved passwords, cookies, and tokens from infected machines. IBM X-Force saw an 84% increase in phishing emails delivering infostealers in 2024. Our statistics on compromised devices track how often those endpoints are breached and what it costs.
• Credential stuffing: using automated tools and leaked credential lists e.g. the 2 billion email addresses Have I Been Pwned loaded from Synthient's data to try old usernames/passwords on new sites.
• Third party breaches: credentials stolen from partners/vendors e.g. the Change Healthcare breach.
• Insider misuse: employees abusing their access. Often these methods overlap e.g., stolen passwords from one breach get used to phish or log in elsewhere.

• What role does AI play in credential attacks?

AI is a force multiplier on both sides. Attackers use AI for Adversary in the Middle phishing kits, e.g. EvilProxy, that can steal MFA tokens in real time, and to craft highly convincing phishing lures and deepfakes. IBM found 16% of breaches in its 2025 study involved attackers using AI, and one in four malicious breaches in its 2026 study was AI-enabled. Shadow AI (employees uploading data to public AI tools) also increases risk. On defense, organizations using AI and automation extensively contained breaches about 80 days faster, saving roughly $1.9M per breach in 2025.

• How can organizations protect against compromised credentials?

Best practices include enforcing phishing resistant multi factor authentication FIDO2 passkeys or hardware tokens everywhere attackers cannot phish a passkey like a password. Monitor for leaked credentials: use threat feeds the FBI, Troy Hunt’s HIBP, etc. to block logins with known breached passwords. Implement least privilege so that any stolen account has minimal access. Scan code repos and cloud assets for exposed secrets API keys, tokens. And importantly, assume breach: have IR plans, isolate critical data, and employ analytics to catch anomalous logins quickly. The data shows that faster detection directly translates to lower costs, so investing in identity monitoring pays dividends.

The 2024–2026 data make one fact unmistakable: the cyber risk landscape is defined by identity. Far from being a fringe issue, stolen and misused credentials remain one of the main paths into networks and appear in a large share of breaches. Attackers have industrialized identity theft, they buy access from brokers, harvest billions of passwords, and use AI to bypass protections. Meanwhile, organizations that ignore this trend pay a steep price in downtime, fines, and damaged trust.

Going forward, defenders must shift their focus. Perimeter firewalls and signature based detection will not stop a legitimate login with a wrong password. Instead, companies must architect resilience: eliminate phishable factors, adopt passkeys, tightly govern every credential human and machine, and use AI to spot the unusual quickly.
