Redline Dropped Through MSIX Package, Author&colon
Key Findings:
An unusual malicious bundle (a collection of malicious programs distributed in the form of a single installation file, self-extracting archive or other file with installer-type functionality) recently caught our eye. Its main payload is the widespread RedLine stealer. Discovered in March 2020, RedLine is currently one of the most common Trojans used to steal passwords and credentials from browsers, FTP clients and desktop messengers. It is openly available on underground hacker forums for just a few hundred dollars, a relatively small price tag for malware.
RedLine is a stealer distributed as cracked games, applications, and services. The malware steals information from web browsers, cryptocurrency wallets, and applications such as FileZilla, Discord, Steam, Telegram, and VPN clients. The binary also gathers data about the infected machine, such as the running processes, antivirus products, installed programs, the Windows product name, the processor architecture, etc. The stealer implements the following actions that extend its functionality: Download, RunPE, DownloadAndEx, OpenLink, and Cmd. The extracted information is converted to the XML format and exfiltrated to the C2 server via SOAP messages.
