What Attackers Are
Targeting Right Now
The 2026 threat landscape looks different from the one most testing programs were built for. Vulnerability exploitation, third-party compromise, and shadow AI are driving breach patterns that standard annual scopes were not designed to surface.
| Threat | Severity | Impact | Trend | Key stat | Source |
|---|---|---|---|---|---|
|
Copy Fail Kernel Exploit
Active CVE
|
critical |
A nine-year-old kernel flaw lets any local user gain root access with a 732-byte exploit. Affects nearly every Linux distribution since 2017, including cloud and Kubernetes environments. |
Active exploitation |

|
Vulnerability Exploitation
Initial Access
|
critical |
Exploiting vulnerabilities overtook stolen credentials as the top breach entry point for the first time in 19 years. AI has cut the gap between disclosure and exploitation from months to hours. |
New top vector |
31%
of breaches begin with vulnerability exploitation

Third-Party Compromise
Supply chain
|
critical |
A single compromised vendor or integration now creates a direct path into multiple downstream organizations. |
+60% year over year |
48%
of all breaches now involve a third party
|

Shadow AI Usage
Shadow AI
|
critical |
Most employees using AI on corporate devices connect through personal, non-corporate accounts, often uploading source code and sensitive documents without security team visibility. |
Tripled year over year |
67%
employees access AI through non-corporate accounts on work devices

Patch Velocity Gap
Vulnerability Management
|
high |
Median time to patch keeps growing while must-patch volume rises. The gap between attacker speed and remediation speed is widening. |
+34% year over year |
Median
time to patch increased from 32 to 43 days

Mobile Phishing
Social Engineering
|
high |
Attackers are shifting to mobile-centric techniques, fake texts and voice calls, with far higher success rates than email phishing. |
+40% success rate vs. email |

AI Bot Traffic
AI Surfaces
|
high |
AI crawler and fetcher traffic is surging while human web traffic stays flat, reshaping how applications and APIs get probed. |
+21% month over month |
AI bot traffic growing 21% monthly vs. 0.3% human traffic

Ransomware
Malware
|
high |
Ransomware involvement keeps rising. Most victims now refuse to pay, but attack volume and encryption speed continue to increase. |
Rising |
Ransomware involved in 48% of breaches, up from 44%
|

Credential Abuse
Identity
|
high |
While vulnerability exploitation now leads as the top single entry point, stolen and reused credentials remain a major factor in breaches, particularly when combined with phishing. |
Declining as top vector, still significant |
Credential abuse accounts for 13% of breaches as a single vector
|

Human Element Risk
Social Engineering
|
high |
The human element (social engineering, error, and misuse) remains involved in most breaches. |
Majority of breaches |
Human element involved in 62% of breaches
