A new, sophisticated variant of the Mirai botnet, dubbed "Broadside," is actively exploiting a command injection vulnerability (CVE-2024-3721) in TBK Digital Video Recorder (DVR) devices. According to research from Cydome, the campaign specifically targets the maritime logistics sector, where these DVRs are common. Broadside is more advanced than typical Mirai variants, using stealthier techniques and a custom C2 protocol. Crucially, its goals extend beyond DDoS to include credential harvesting and lateral movement, turning compromised DVRs into strategic footholds on vessel networks.
