Renamed CnCrypt Driver Alinubx.sys Terminates 145 Security Processes via Microsoft-Signed BYOVD in GitHub LastPass Lure

A renamed Microsoft-signed CnCrypt driver enables kernel-level AV/EDR termination in a GitHub-distributed LastPass infostealer. The attack leverages attestation signing gaps and DLL side-loading, bypassing current blocklists. It signals broader weaponization of legitimate driver pipelines for credential theft.

Next steps include monitoring for configuration-enabled variants that activate the driver’s full capabilities and tracking similar renamed submissions to the attestation program. Defenders should enforce driver load policies beyond the default blocklist and correlate kernel driver installs with unsigned or side-loaded binaries.

⚡ Prediction

Microsoft: Alinubx.sys and CnCrypt variants added to blocklist within 45 days after public disclosure.
