VERY IMPORTANT

A phishing campaign has been identified where attackers impersonate sales staff from specific overseas companies, requesting quotation modifications and product version confirmations. The email contains a malicious GZ compressed file that, when extracted, delivers an injector-type executable. This injector employs multiple UAC bypass techniques including SSPI-based authentication and CMSTPLUA COM exploitation to gain elevated privileges. It then performs BYOVD attacks using the vulnerable DCRCVDrv.sys driver to terminate security products through kernel-level access. Following security product neutralization, the injector uses process hollowing to inject PhantomStealer into the legitimate AddInProcess32.exe process. PhantomStealer then executes comprehensive information theft including keylogging, screen capture, browser credentials, cryptocurrency wallet data, and clipboard manipulation to replace wallet addresses with attacker-controlled ones.
