Hakuna Matata ransomware
Hakuna Matata ransomware is a ransomware payload observed in a multi-stage phishing campaign reported by FortiGuard Labs, primarily targeting users in Russia. The infection chain relies on social engineering rather than software exploits: victims are lured with fake business or accounting documents in compressed archives containing malicious LNK shortcut files that launch PowerShell, download staged components from GitHub, and ultimately lead to deployment of multiple payloads. In this campaign, Hakuna Matata ransomware is delivered after other malware stages, including Amnesia RAT, and alongside a WinLocker component.
Its core behavior is file encryption across a wide range of files, appending the extension "@NeverMind12F" (also described as "NeverMind12F"). The ransomware drops ransom notes, changes the desktop wallpaper, and kills key processes. In parallel, associated WinLocker functionality fully blocks the desktop, enforces system lockout, and displays coercive Russian-language ransom demands and countdown-style pressure messages. The broader campaign also included clipboard hijacking that replaces cryptocurrency wallet addresses with attacker-controlled values.
The surrounding intrusion includes significant defense evasion and system impairment before ransomware deployment. Reported behaviors in the campaign include repeated UAC prompting to obtain elevated privileges, disabling Microsoft Defender via the Defendnot tool by registering a fake antivirus product, extensive registry modifications to disable monitoring and administrative tools, adding filesystem exclusions, disabling Windows Recovery Environment, deleting backup catalogs, and removing Volume Shadow Copies. Payloads were hosted across GitHub and Dropbox to blend into legitimate traffic and improve resilience. High-confidence associated malware in the same campaign includes Amnesia RAT, which provided persistence, credential theft, session theft, crypto-wallet theft, screenshots, audio capture, remote command execution, and exfiltration via Telegram and file-hosting services.
