Linux Backdoor Delivered via Malicious RAR Filenames

🛡️ Trellix researchers describe a Linux-focused infection chain that uses a malicious RAR filename to trigger command execution. The filename embeds a Base64-encoded Bash payload that leverages shell command injection when untrusted filenames are parsed, allowing an ELF downloader to fetch and run an architecture-specific binary. The chain ultimately delivers the VShell backdoor, which runs in memory to evade disk-based detection.

Ex-Developer Jailed for Deploying Kill-Switch Malware

🛑 A former software developer was sentenced to four years in prison after intentionally sabotaging his employer's servers with custom malware that included a kill switch. Davis Lu, 55, abused his access in 2019 to introduce infinite-loop Java code, delete coworker profiles, and deploy a kill switch named 'IsDLEnabledinAD' that locked out users when his Active Directory account was disabled. The DOJ said the incident, reportedly at Eaton Corporation, disrupted thousands of users and caused hundreds of thousands of dollars in losses.
