A suspected China-based threat actor has been linked to a series of cyber attacks targeting high-profile organizations in Southeast Asia since at least October 2023. The espionage campaign targeted organizations in various sectors spanning government ministries in two different countries, an air traffic control organization, a telecoms company, and a media outlet, the Symantec Threat Hunter Team said in a new report shared with The Hacker News. The attacks, which leveraged tools previously identified as linked to China-based advanced persistent threat (APT) groups, are characterized by the use of both open-source and living-off-the-land (LotL) techniques. This includes the use of reverse proxy programs such as Rakshasa and Stowaway , as well as asset discovery and identification tools, keyloggers, and password stealers. Also deployed during the course of the attacks is PlugX (aka Korplug), a remote access trojan put to use by several Chinese hacking groups. "The threat ac...

The U.S. government on Tuesday unsealed charges against a Chinese national for allegedly breaking into thousands of Sophos firewall devices globally in 2020. Guan Tianfeng (aka gbigmao and gxiaomao), who is said to have worked at Sichuan Silence Information Technology Company, Limited, has been charged with conspiracy to commit computer fraud and conspiracy to commit wire fraud. Guan has been accused of developing and testing a zero-day security vulnerability used to conduct the attacks against Sophos firewalls. "Guan Tianfeng is wanted for his alleged role in conspiring to access Sophos firewalls without authorization, cause damage to them, and retrieve and exfiltrate data from both the firewalls themselves and the computers behind these firewalls," the U.S. Federal Bureau of Investigation (FBI) said . "The exploit was used to infiltrate approximately 81,000 firewalls." The then-zero-day vulnerability in question is CVE-2020-12271 (CVSS score: 9.8), a severe S...

Users of Cleo-managed file transfer software are being urged to ensure that their instances are not exposed to the internet following reports of mass exploitation of a vulnerability affecting fully patched systems. Cybersecurity company Huntress said it discovered evidence of threat actors exploiting the issue en masse on December 3, 2024. The vulnerability, which impacts Cleo's LexiCom, VLTransfer, and Harmony software, concerns a case of unauthenticated remote code execution. The security hole is tracked as CVE-2024-50623 (CVSS score: 9.8), with Cleo noting that the flaw is the result of an unrestricted file upload that could pave the way for the execution of arbitrary code. The Illinois-based company, which has over 4,200 customers across the world, has since issued another advisory (CVE-2024-55956), warning of a separate "unauthenticated malicious hosts vulnerability that could lead to remote code execution." The development comes after Huntress said the pat...
