DarkGate Malware Rapidly Spreads via Messaging Platforms

    Changes are imminent in the digital world as DarkGate, a prominent malware, stealthily creeps into the spotlight. Disguised skillfully as a PDF file, DarkGate swiftly propagates through instant messaging platforms, including – but not limited to – Skype and Microsoft Teams. The malware operates meticulously: it first delivers a Visual Basic for Applications (VBA) loader script, which, when opened, amicably downloads and executes an AutoIt script. Unsettlingly, this sequence eventually launches DarkGate in its full destructive capacity(source).

    The backdoor paved by DarkGate into messaging accounts remains shrouded in intrigue. Leaked credentials are points of high suspicion, though the residue of preceding compromises cannot be disregarded. While it was privately used initially, the modus operandi of DarkGate has shifted dramatically with an eye towards commodification, as the malware is now rented to other threat actors, inadvertently nourishing the cybercrime ecosystem(source).

    DarkGate’s infiltration mechanisms encompass more than just the distribution of the VBA loader script. It serves as an effective backdoor for stealing sensitive data, conducting nefarious cryptocurrency mining, and granting remote control access to the troubled hosts. Furthermore, it presents the capability to download additional payloads, namely the iniquitous Remcos RAT.

    The Americas bear the brunt of DarkGate’s destructive spread as the primary cyberattack ground zero. However, Asia, the Middle East, and Africa bear the markers of advancing infiltration. The implications of this distribution pattern cannot be overstated, right from corporate security to international cybersecurity frameworks.

    Astonishingly, the sinister attack technique deployed by DarkGate finds parallels with a malspam campaign reported in August 2023. The sole distinction lies in the route of initial access, betraying an unnerving adaptability in the malware’s frequency, trajectory, and impact. Caution is the word as payloads of this nature threaten not just individual systems, but potentially entire networks and linked digital clusters.
