"The FBI warns that the extortion group 'Silent Ransom Group' (SRG) is physically entering law firm offices. Attackers impersonate IT staff to plug thumb drives into computers to steal sensitive data. The group primarily uses callback phishing but has escalated to in-person social engineering since Spring 2026. Organizations are advised to restrict USB port access and verify credentials of visitors."
