Your MTTD Looks Great. Your Post-Alert Gap Doesn't

thehackernews.com · 3 months ago

Anthropic recently restricted a model after it autonomously exploited zero-day vulnerabilities across major operating systems and browsers, highlighting the increasing speed of attacks. Traditional security operations centers are slowed by a “post-alert gap,” the time between an alert firing and a thorough investigation, often taking 20 to 40 minutes. Artificial intelligence can compress this gap by rapidly investigating every alert and optimizing detection rules, shifting focus from detection speed to investigation coverage and detection improvement. Security teams should prioritize metrics like investigation coverage rate and hunt-driven detection creation to measure true security posture.

One Uppercase Letter Breaks Every Nuxt App

simonkoeck.com · 3 months ago

A vulnerability has been identified in the h3 HTTP framework, commonly used with Nuxt and Nitro applications. The issue stems from a case-sensitive check for the Transfer-Encoding header, which can lead to request smuggling when a reverse proxy handles chunked requests differently. Attackers can exploit this by crafting requests with a case variation of "chunked", causing the proxy and h3 to disagree on request boundaries, allowing for the injection of malicious requests that bypass security measures. The vulnerability, resolved in h3 v1.15.5, has been assigned CVE-2026-23527 and GHSA-mp2g-9vg9-f4cg.

Critical Axios Vulnerability Enables Remote Code Execution, PoC Released

gbhackers.com · 3 months ago

A critical vulnerability, CVE-2026-40175, has been discovered in the Axios HTTP client library, allowing for Remote Code Execution and potential cloud infrastructure compromise. The flaw stems from a lack of HTTP header sanitization, enabling attackers to bypass AWS security controls through a "Gadget" attack chain that requires no direct user input. Affected versions include all Axios releases prior to 1.15.0, and immediate updates are recommended to mitigate the risk by validating header values and preventing request smuggling. This allows attackers to retrieve session tokens and steal IAM credentials.

VIPERTUNNEL Python Backdoor Hidden in Fake DLL, Obfuscated Loader Chain

gbhackers.com · 3 months ago

Hackers are employing a stealthy Python backdoor named VIPERTUNNEL, which uses a fake DLL and layered obfuscation to establish covert network tunnels. The backdoor uses a sitecustomize.py file to auto-load code, and employs techniques like Base85 encoding and control-flow flattening to evade detection. It ultimately creates a SOCKS5 proxy to communicate with a command-and-control server over port 443, facilitating lateral movement and data exfiltration. This backdoor is linked to UNC2165/EvilCorp activity and is associated with credential-stealing tool ShadowCoil.
