Vendetta is a threat actor active since at least 2020 that has been associated with socially engineered phishing campaigns delivering remote-access malware and custom backdoor components. The group is noted for realistic impersonation lures themed around law enforcement, public health, and other trusted organizations in order to persuade recipients to open malicious attachments. Reported lure themes have spoofed government and institutional entities in multiple countries, indicating broad opportunistic targeting rather than a single narrowly focused victim set. Vendetta has been linked to a malware chain involving an obfuscation component known as RoboSki and a backdoor referred to as ReZer0. RoboSki concealed encrypted shellcode within image pixels, while ReZer0 used hard-coded internal instructions to determine execution flow and supported functions such as downloading and executing additional payloads, loading plugins in memory, injecting plugins into system processes, optional scheduled-task persistence, and anti-analysis and antivirus-evasion checks. ReZer0 was assessed as still under development during observed activity, with some embedded functionality apparently unused. The actor has also been historically associated with use of NanoCore and Remcos remote-access tooling. Across these toolsets, observed capabilities include phishing-based initial access, in-memory payload loading, persistence through scheduled tasks, process injection, keylogging, remote command execution, and theft of information from compromised systems. Vendetta has been assessed as likely seeking commercial or business intelligence from victim organizations, making espionage the most plausible dominant motivation based on available evidence. Attribution remains limited. One reporting stream associated the actor with Turkish indicators, while other development artifacts suggested a broader possible European connection, including claimed Italian references. The available evidence supports only a tentative association with Turkey and does not establish a definitive state nexus.
