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

Over 700 Malicious Typosquatted Libraries Found On RubyGems Repository

April 16, 2020Ravie Lakshmanan
As developers increasingly embrace off-the-shelf software components into their apps and services, threat actors are abusing open-source repositories such as RubyGems to distribute malicious packages, intended to compromise their computers or backdoor software projects they work on. In the latest research shared with The Hacker News, cybersecurity experts at ReversingLabs revealed over 700 malicious gems — packages written in Ruby programming language — that supply chain attackers were caught recently distributing through the RubyGems repository. The malicious campaign leveraged the typosquatting technique where attackers uploaded intentionally misspelled legitimate packages in hopes that unwitting developers will mistype the name and unintentionally install the malicious library instead. ReversingLabs said the typosquatted packages in question were uploaded to RubyGems between February 16 and February 25, and that most of them have been designed to secretly steal funds by r

February 19, 2020Ravie Lakshmanan
The U.S. Department of Homeland Security's Cybersecurity and Infrastructure Security Agency (CISA) earlier today issued a warning to all industries operating critical infrastructures about a new ransomware threat that if left unaddressed could have severe consequences. The advisory comes in response to a cyberattack targeting an unnamed natural gas compression facility that employed spear-phishing to deliver ransomware to the company's internal network, encrypting critical data and knocking servers out of operation for almost two days. "A cyber threat actor used a spear-phishing link to obtain initial access to the organization's information technology network before pivoting to its operational technology network. The threat actor then deployed commodity ransomware to encrypt data for impact on both networks," CISA noted in its alert. As ransomware attacks continue to escalate in frequency and scale , the new development is yet another indication that p
