New GpCode spreading

Two hours ago we started receiving multiple emails from users with encrypted documents.

Virus.Win32.GpCode.ae is responsible for this outbreak – this is a new variant of something we’ve reported on before. It’s currently affecting Russian Internet users and doesn’t seem to be spreading in the West.

This encryptor is detected with detection for the previous version of this program – Virus.Win32.GpCode.ad.

In comparison to the previous version, one of the main differences is that the encryption algorithm used is stronger – the previous version used RSA 67 bit, but this one uses RSA 260 bit. We’re working on the decryption algorithm.

We’ll update you as we get more information.

Kimsuky (also known as Thallium, Black Banshee and Velvet Chollima) is a prolific and active threat actor primarily targeting Korea-related entities. In early 2022, we observed this group was attacking the media and a think-tank in South Korea.

Andariel deploys DTrack and Maui ransomware

Earlier, the CISA published an alert related to a Stairwell report, “Maui Ransomware.” Our data should openly help solidify the attribution of the Maui ransomware incident to the Korean-speaking APT Andariel, also known as Silent Chollima and Stonefly.
