New USBCulprit Espionage Tool Steals Data From Air-Gapped Computers

New USBCulprit Espionage Tool Steals Data From Air-Gapped Computers

June 04, 2020Ravie Lakshmanan
A Chinese threat actor has developed new capabilities to target air-gapped systems in an attempt to exfiltrate sensitive data for espionage, according to a newly published research by Kaspersky yesterday. The APT, known as Cycldek, Goblin Panda, or Conimes, employs an extensive toolset for lateral movement and information stealing in victim networks, including previously unreported custom tools, tactics, and procedures in attacks against government agencies in Vietnam, Thailand, and Laos. "One of the newly revealed tools is named USBCulprit and has been found to rely on USB media in order to exfiltrate victim data," Kaspersky said. "This may suggest Cycldek is trying to reach air-gapped networks in victim environments or relies on physical presence for the same purpose." First observed by CrowdStrike in 2013, Cycldek has a long history of singling out defense, energy, and government sectors in Southeast Asia, particularly Vietnam, using decoy documents th

Chinese Researchers Disrupt Malware Attack That Infected Thousands of PCs

May 27, 2020Ravie Lakshmanan
Chinese security firm Qihoo 360 Netlab said it partnered with tech giant Baidu to disrupt a malware botnet infecting over hundreds of thousands of systems. The botnet was traced back to a group it calls ShuangQiang (also called Double Gun ), which has been behind several attacks since 2017 aimed at compromising Windows computers with MBR and VBR bootkits , and installing malicious drivers for financial gain and hijack web traffic to e-commerce sites. In addition to using images uploaded to Baidu Tieba to distribute configuration files and malware — a technique called steganography — the group has begun using Alibaba Cloud storage to host configuration files and Baidu's analytics platform Tongji to manage the activity of its infected hosts, the researchers said. The initial compromise relies on luring unsuspecting users to install game launching software from sketchy game portals that contain malicious code under the guise of a patch. Once the user downloads and inst
