Linux BambooToken Malware Uses MQTT C2 for Remote Shell Access and File Exfiltration

·

cyber security, Cyber Security News, Linux, Malware

A Linux variant of the BambooToken backdoor uses MQTT as its command-and-control channel, enabling operators to profile compromised hosts, execute shell commands, and transfer files through broker-mediated topics. Analysis of a statically linked x86-64 ELF sample shows that its configuration, task routing, and network payloads are obfuscated with separate XOR routines. The examined sample, SHA-256 […]
