Per Sekoia, the activity involves the weaponization of CVE-2025-8088, a path traversal flaw in WinRAR, to launch an HTML Application payload dubbed GammaPhish, which is then…

AI-Driven Exploitation is Destroying Vulnerability Management. Here’s How to Handle It.

AI-driven exploitation timelines are rapidly shrinking, and they are not going to stop shrinking. Vulnerabilities are being discovered, reproduced, and weaponized faster than ever in the history of enterprise security. As a result, the window between a vulnerability being disclosed and indiscriminate exploitation observed across the internet is now measured in hours, not days. The…

Verizon DBIR: Vulnerability exploitation is the dominant initial access vector

Vulnerability exploitation has overtaken stolen credentials as the most common way attackers gain initial access to target networks, according to the 2026 Verizon Data Breach Investigations Report. This is the first time credential theft has been knocked off the top spot in the report’s 19-year history, the company noted. Known initial access vectors over time…

AI shrinks vulnerability exploitation window to hours

Time has become organizations’ biggest vulnerability because the gap between vulnerability discovery and exploitation has narrowed to hours, according to Synack’s 2026 State of Vulnerabilities Report. Total vulnerabilities by severity (2022-2025) (Source: Synack) AI expands the attack surface Agentic AI systems that act autonomously across systems introduce new risks that require human expertise to identify…

cPanel CVE-2026-41940 Under Active Exploitation to Deploy Filemanager Backdoor

A threat actor named Mr_Rot13 has been attributed to the exploitation of a recently disclosed critical cPanel flaw to deploy a backdoor codenamed Filemanager on compromised environments. The attack exploits CVE-2026-41940, a vulnerability impacting cPanel and WebHost Manager (WHM) that could result in an authentication bypass and allow remote attackers to gain elevated control of…

State-sponsored hackers likely behind zero-day attacks on Palo Alto firewalls

Palo Alto Networks believes the in-the-wild exploitation of a zero-day vulnerability (CVE-2026-0300) in its firewalls is likely the work of state-sponsored threat actors. A flaw with no patch (yet) CVE-2026-0300 is a buffer overflow vulnerability in the User-ID Authentication Portal service of Palo Alto Networks PAN-OS software, and can be exploited by unauthenticated attackers sending…

LiteLLM CVE-2026-42208 SQL Injection Exploited within 36 Hours of Disclosure

In yet another instance of threat actors quickly jumping on the exploitation bandwagon, a newly disclosed critical security flaw in BerriAI’s LiteLLM Python package has come under active exploitation in the wild within 36 hours of the bug becoming public knowledge. The vulnerability, tracked as CVE-2026-42208 (CVSS score: 9.3), is an SQL injection that could…

Data Breaches, AI Expansion, and Cloud Security Define This Week’s Cyber Landscape in April 2026

Major Threats & Vulnerabilities Vulnerability Scoring and Exploitation Trends The NIST Adjusts Scoring Amid CVE Spike report highlights a 260%+ increase in CVE submissions since 2020. To manage the surge, NIST will prioritize high-impact vulnerabilities, potentially leaving many without full scoring data. Security teams must adapt to inconsistent vulnerability data and prepare for potential blind…

CVE-2023-33538 under attack for a year, but exploitation still unsuccessful

Hackers have targeted CVE-2023-33538 flaw in old TP-Link routers for a year, but no successful exploitation has been seen so far. Hackers have been trying for over a year to exploit a serious flaw, tracked as CVE-2023-33538 (CVSS score of 8.8), in outdated TP-Link routers, but so far without success. The vulnerability is a command…

Patch windows collapse as time-to-exploit accelerates

The gap between vulnerability disclosure and exploitation is drastically decreasing, putting security teams’ patching practices on notice. According to Rapid7’s latest Cyber Threat Landscape Report, confirmed exploitation of newly disclosed high- and critical-severity vulnerabilities (CVSS 7-10) increased 105% year to 146 in 2025, up from 71 in 2024. Moreover, the median time from vulnerability publication…

Vulnerabilities from years ago still opening doors for attackers

Exploitation timelines continued to compress in enterprise environments, with newly disclosed flaws reaching active use almost immediately and older weaknesses remaining active years after disclosure. (Source: Cisco Talos) Findings from Cisco Talos’ 2025 Year in Review show how attackers combined rapid weaponization with long-term exposure spanning infrastructure, identity systems, and user workflows. Top-targeted vulnerabilities show…

Critical Langflow Flaw CVE-2026-33017 Triggers Attacks within 20 Hours of Disclosure

A critical security flaw impacting Langflow has come under active exploitation within 20 hours of public disclosure, highlighting the speed at which threat actors weaponize newly published vulnerabilities. The security defect, tracked as CVE-2026-33017 (CVSS score: 9.3), is a case of missing authentication combined with code injection that could result in remote code execution. “The…

How ‘silent probing’ can make your security playbook a liability

For years, cyberattacks followed a familiar pattern: reconnaissance, exploitation, persistence, impact. Defenders built their strategies around that cycle, patching vulnerabilities, monitoring indicators, and working to reduce dwell time. But a quieter shift is underway. Today’s most sophisticated adversaries are using AI to study how organizations defend themselves. They run what we call “silent probing campaigns:”…

Edge systems take the brunt of internet-wide exploitation attempts

Internet-facing VPNs, routers, and remote access services absorbed sustained exploitation attempts throughout the second half of 2025, with nearly 3 billion malicious sessions recorded over 162 days. The concentration on edge infrastructure aligns with how attackers pursue initial access across the public internet. GreyNoise’s State of the Edge data set covers 2.97 billion sessions observed…

CVE-2026-2441: Google Patches Chrome Zero-Day Exploited in the Wild
