According to the cybersecurity company, the targeted entity had worked for a city with close ties to Ukraine in the past.\\n\\n\\n\\nSocGholish (aka FakeUpdates), linked to a financially motivated operator tracked as TA569 (aka Gold Prelude, Mustard Tempest, Purple Vallhund, and UNC1543), serves as an initial access broker, allowing other threat actors to drop a wide range of payloads. Some of its known customers are Evil Corp, LockBit, Dridex, and Raspberry Robin.\\n\\nThe attack chains typically involve serving fake browser update alerts for Google Chrome or Mozilla Firefox on legitimate-but-compromised websites to trick unsuspecting users into downloading malicious JavaScript that’s responsible for installing a loader, which then fetches additional malware.\\n\\nFor the most part, the attacks single out websites that are poorly secured, taking advantage of known security vulnerabilities in plugins to inject JavaScript code that’s designed to display the pop-up and activate the infection chain.\\n\\nRomCom (aka Nebulous Mantis, Storm-0978, Tropical Scorpius, UNC2596, or Void Rabisu), on the other hand, is the name assigned to a Russia-aligned threat actor that’s known to dabble in both cybercrime and espionage operations since at least 2022.\\n\\nThe threat actor leverages several methods, including spear-phishing and zero-day exploits, to breach target networks and drop the eponymous remote access trojan (RAT) on victim machines. Attacks mounted by the hacking group have singled out entities in Ukraine, as well as NATO-related defense organizations.\\n\\nIn the attack analyzed by Arctic Wolf, the fake update payload allows the threat actors to run commands on the compromised machine by means of a reverse shell established to a command-and-control (C2) server. This includes conducting reconnaissance and dropping a custom Python backdoor codenamed VIPERTUNNEL.\\n\\n\\n\\nAlso delivered is a RomCom-linked DLL loader that launches the Mythic Agent, a crucial component of the cross-platform, post-exploit, red teaming framework that communicates with a corresponding server to support command execution, file operations, and others.\\n\\nWhile the attack was ultimately unsuccessful and was blocked before it could progress any further, the development shows the RomCom threat actor’s continued interest in targeting Ukraine or entities providing assistance to the country, no matter how tenuous the connection may be.\\n\\n\\”The timeline from infection via [the fake update] to the delivery of RomCom’s loader was less than 30 minutes,\\” Jacob Faires said. \\”Delivery is not made until the target’s Active Directory domain has been verified to match a known value provided by the threat actor.\\”\\n\\n\\”The widespread nature of SocGholish attacks and the relative speed at which the attack progresses from initial access to infection makes it a potent threat to organizations worldwide.\\”\\n\\nFound this article interesting?
