⚡ Weekly Recap: Telecom Sleeper Cells, LLM Jailbreaks, Apple Forces U.K. Age Checks and More
Summary
A critical flaw in Citrix NetScaler ADC and NetScaler Gateway (CVE-2026-3055, a CVSS score of 9.3 measuring severity on a 0-10 scale) is being actively exploited to leak sensitive information through insufficient input validation, a failure to properly check data before processing it. The vulnerability only affects systems configured as SAML Identity Providers (SAML IDPs, which are services that verify user identities). Additionally, a Chinese state-sponsored group called Red Menshen deployed stealthy kernel implants called BPFDoor deep in telecom networks worldwide to secretly monitor traffic without being detected.
Solution / Mitigation
Rapid7 has released a scanning script designed to detect known BPFDoor variants across Linux environments.
