New RedLine malware version distributed as fake Omicron stat counter

Experts warn of a new variant of the RedLine malware that is distributed via emails as fake COVID-19 Omicron stat counter app as a lure.


Fortinet researchers have spotted a new version of the RedLine info-stealer that is spreading via emails using a fake COVID-19 Omicron stat counter app as a lure.

The RedLine malware allows operators to steal several information, including credentials, credit card data, cookies, autocomplete information stored in browsers, cryptocurrency wallets, credentials stored in VPN clients and FTP clients. The malicious code can also act as a first-stage malware.

Upon executing the Omicron Stats.exe, it unpacks resources encrypted with triple DES using ciphermode ECB and padding mode PKCS7. Then the unpacked resources are injected into vbc.exe and a scheduled task is created to establish persistence.


The new variant implements several new features, it is able to steal more information from the victim’s Windows Management Instrumentation (WMI) such as:
