A malware distribution campaign leveraging digitally signed binaries, deceptive packaging, and browser hijackers has been uncovered. The campaign centers around two malicious applications, ImageLooker.exe and Calendaromatic.exe, delivered via self-extracting 7-Zip archives. These artifacts align with the TamperedChef malware campaign, which uses trojanized productivity tools for initial access and data exfiltration. The malware employs NeutralinoJS framework, Unicode homoglyphs, and multiple digital signers to bypass detection. The campaign exploits user behavior through SEO poisoning and malvertising, masquerading as legitimate software. This sophisticated approach highlights the evolving tactics of threat actors in weaponizing PUAs and abusing digital code signing to evade security measures.

A seemingly harmless desktop application named calendaromatic.exe was discovered to be a sophisticated malware utilizing NeutralinoJS, Unicode homoglyphs, and hidden payloads. The malware, distributed through an aggressive ad campaign, exploited NeutralinoJS's native APIs to interact directly with the host operating system. The key to its operation was a function named clean() that scanned for Unicode homoglyphs in holiday JSON data, using them to encode hidden instructions. This technique allowed the malware to receive and execute arbitrary code smuggled into holiday names using lookalike characters. The investigation was accelerated by AI, which helped parse and annotate the minified JavaScript code.
