SESAMEOP: NOVEL BACKDOOR USES OPENAI ASSISTANTS API FOR COMMAND AND CONTROL
Summary from the TLDR InfoSec newsletter
A new cybersecurity threat called SesameOp leverages the OpenAI Assistants API as a covert channel for command and control, allowing attackers to communicate with malware undetected. By embedding its communication within legitimate API traffic, SesameOp enables persistent access and remote control of compromised systems while evading traditional detection methods. It achieves this by leveraging obfuscated code, secure encryption, and creative misuse of built-in API functionality, rather than exploiting specific software vulnerabilities.
