A complicated phishing marketing campaign focusing on Turkish protection and aerospace enterprises has emerged, delivering a extremely evasive variant of the Snake Keylogger malware by means of fraudulent emails impersonating TUSAŞ (Turkish Aerospace Industries).
The malicious marketing campaign distributes recordsdata disguised as contractual paperwork, particularly utilizing the filename “TEKLİF İSTEĞİ – TUSAŞ TÜRK HAVACILIK UZAY SANAYİİ_xlsx.exe” to deceive recipients into executing the payload.
The Snake Keylogger variant demonstrates superior persistence capabilities and complex evasion strategies that permit it to function undetected inside compromised programs.
As soon as executed, the malware instantly establishes a number of layers of persistence whereas concurrently implementing anti-detection mechanisms to make sure long-term entry to sufferer programs.
The marketing campaign’s focused strategy towards protection business contractors signifies a strategic give attention to high-value intelligence gathering operations.
Malwation researchers recognized this specific pressure throughout their evaluation of current phishing campaigns, noting the malware’s subtle use of official Home windows utilities to take care of persistence and evade safety controls.

The pattern, with SHA256 hash 0cb819d32cb3a2f218c5a17c02bb8c06935e926ebacf1e40a746b01e960c68e4, presents as a PE32 executable written in .NET, using a number of unpacking layers to hide its true performance.
The keylogger’s major targets embody credentials, cookies, and monetary info extracted from over 30 totally different browsers and electronic mail purchasers, together with Chrome, Firefox, Outlook, and Thunderbird.

Moreover, the malware harvests autofill knowledge, bank card info, obtain histories, and prime websites from compromised programs earlier than exfiltrating the stolen knowledge by way of SMTP to mail.htcp.properties servers.
Superior Persistence and Evasion Mechanisms
The malware employs a dual-pronged strategy to determine persistence whereas evading detection programs.
Upon execution, it instantly invokes PowerShell so as to add itself to Home windows Defender’s exclusion checklist utilizing the command Add-MpPreference -Excl, successfully neutralizing the built-in antimalware safety.
This operation is executed by means of the NtCreateUserProcess system name, launching powershell.exe with elevated privileges to change safety configurations.
Concurrently, the malware creates a scheduled process named “UpdatesoNqxPR” utilizing schtasks.exe to make sure automated execution at system startup.
The scheduled process creation course of includes producing an XML configuration file that defines the execution parameters, permitting the malware to persist throughout system reboots with out consumer interplay.
This method leverages official Home windows process scheduling performance, making detection considerably tougher for conventional safety options.
