Loading malware…
Themida is a commercial software protector/packer used to obfuscate and protect executables, and in the provided reporting it is repeatedly referenced as a defense-evasion layer applied to malware. The content describes Themida-packed or Themida-protected payloads in multiple campaigns. In one Acronis-reported campaign distributing fake game cheats via GitHub and related lures, the downloaded payload background.exe was identified as a Themida-packed Vidar Stealer 2.0 sample. In Lazarus Group activity, including Operation Dream Job, malicious .db files were packed with Themida to evade detection. ESET also reported Lazarus using Themida-protected binaries in a South Korea-focused supply-chain-style campaign abusing the WIZVERA VeraPort software installation ecosystem; the signed initial downloader and another component were described as Themida-protected, with the version estimated at roughly 2.0 to 2.5. Across the cited reporting, Themida is associated with malware delivery and concealment rather than being the final payload itself, and is linked in the content to Lazarus operations and to Vidar Stealer 2.0 delivery. High-confidence behaviors directly mentioned are packing/protecting binaries to hinder analysis and evade detection. No standalone infection vector or IoCs specific to Themida itself are provided beyond its use as a protection layer on malicious files.

The batch file extracted from the first zip archive has two layers of obfuscation... The first layer of the obfuscation is a simple substitution cipher.
Appendix D lists "T1027.001 Obfuscated Files or Information: Binary Padding"; the report discusses use of VMProtect, Themida, and script/binary obfuscation.
The attacker uses a commercial packing program called Themida to pack the malware in order to evade anti-virus software detection.
After virtualization, the code is transformed into a complex, obfuscated form that is hard to analyze. The devirtualizer restores the original logic, making the code readable again.
