TrickBot Malware Gets UEFI/BIOS Bootkit Feature to Remain Undetected

TrickBot Malware Gets UEFI/BIOS Bootkit Feature to Remain Undetected

December 03, 2020Ravie Lakshmanan
TrickBot , one of the most notorious and adaptable malware botnets in the world, is expanding its toolset to set its sights on firmware vulnerabilities to potentially deploy bootkits and take complete control of an infected system. The new functionality, dubbed " TrickBoot " by Advanced Intelligence (AdvIntel) and Eclypsium, makes use of readily available tools to check devices for well-known vulnerabilities that can allow attackers to inject malicious code in the UEFI/BIOS firmware of a device, granting the attackers an effective mechanism of persistent malware storage. "This marks a significant step in the evolution of TrickBot as UEFI level implants are the deepest, most powerful, and stealthy form of bootkits," the researchers said. "By adding the ability to canvas victim devices for specific UEFI/BIOS firmware vulnerabilities, TrickBot actors are able to target specific victims with firmware-level persistence that survives re-imaging or even device br

New 'MosaicRegressor' UEFI Bootkit Malware Found Active in the Wild

Cybersecurity researchers have spotted a rare kind of potentially dangerous malware that targets a machine's booting process to drop persistent malware. The campaign involved the use of a compromised  UEFI  (or Unified Extensible Firmware Interface) containing a malicious implant, making it the  second known public case  where a UEFI rootkit has been used in the wild. According to  Kaspersky , the rogue UEFI firmware images were modified to incorporate several malicious modules, which were then used to drop malware on victim machines in a series of targeted cyberattacks directed against diplomats and members of an NGO from Africa, Asia, and Europe. Calling the malware framework " MosaicRegressor ," Kaspersky researchers Mark Lechtik, Igor Kuznetsov, and Yury Parshin said a telemetry analysis revealed several dozen victims between 2017 and 2019, all of whom had some ties to North Korea. UEFI is a firmware interface and a replacement for BIOS that improves security, e
