Analysts discovered a new Remcos RAT infection chain starting with a batch file executing encoded commands that creates hidden directories and retrieves encrypted payloads. Unlike earlier campaigns relying on PowerShell-hosted .NET loaders, this variant incorporates DonutLoader shellcode and AutoIt-based staging for in-memory payload delivery. The infection begins with a phishing email containing a malicious batch file named Bestellung.CMD. The chain abuses legitimate Windows utilities including cscript.exe and SyncAppvPublishingServer.vbs to execute Base64-encoded payloads. Additional components are downloaded from cloud storage, including 7Zip tools and password-protected archives containing obfuscated JScript. The final payload consists of DonutLoader shellcode that injects Remcos RAT version 7.2.1 Pro into colorcpl.exe, enabling remote control, credential harvesting, keystroke logging, and additional payload deployment.

A security issue exists in FactoryTalk ViewPoint version 14.0 or below due to improper handling of MSI repair operations. During a repair, attackers can hijack the cscript.exe console window, which runs with SYSTEM privileges. This can be exploited to spawn an elevated command prompt, enabling full privilege escalation.
