Rewterz Threat Alert – Cracked Software Used to Distribute Malware

Severity

High

Analysis Summary

Cracked software is being used in a campaign to distribute multiple instances of malware that have estimated infected some half a million systems. Allegedly cracked versions of software are being used in a campaign to install malware, most of which has been stored on a public code repository platform under a number of different accounts. According to an estimation in a report from Cybereason, a half a million machines may have fallen victim to this campaign. When a victim installs one of the cracked versions of software, they are first infected with the Azorult information stealer. Next, Predator is installed and it downloads further malware from the repository which may include Evasive Monero, an XMRig dropper, STOP ransomware, the Vidar information stealer, the Amadey Trojan, and IntelRapid which is used to steal cryptocurrency. The copies of malware used in the campaign are regularly updated and are packed using Themida. Azorult gains additional layers of obfuscation through the use of the CypherIT Autoit packer.
