The threat actor known as HoneyMyte (aka  Mustang Panda ) has been observed deploying an updated version of the CoolClient backdoor with a signed Windows kernel-mode rootkit that can hide and protect malicious processes, files, registry objects, and command-and-control (C2) network information. Russian cybersecurity vendor Kaspersky said it identified victims in Myanmar, Mongolia, Pakistan, and Russia, including confirmed government entities, with CoolClient consistently deployed as a secondary backdoor following a  PlugX  infection. The kernel component is deployed when CoolClient has full access to the Service Control Manager (SCM) and the SeTcbPrivilege privilege. If those conditions are not met, the malware skips driver deployment and proceeds to the final-stage implant. Kaspersky has also published file hashes, paths, and C2 domains as indicators of compromise (IoCs). "Our analysis confirms that the investigated malware is a new CoolClient variant ...

A new White House memo signed by U.S. President Donald Trump has instructed the National Coordination Center (NCC) to establish a program that would allow private sector companies to take advantage of their "innovative capabilities" to break into foreign Transnational Criminal Organizations (TCOs) and disrupt them. "By partnering with vetted United States companies subject to the direction and oversight of the Federal Government, we will enhance our ability to counter TCO threats and combat transnational cybercrime, fraud, and other predatory schemes against American citizens," the memo reads . To that end, the NCC has been tasked with setting up a program that allows authorized companies to conduct two types of operations against TCOs upon obtaining approval: cyber surveillance operations, which can access sensitive data without authorization from the owner or operator, and cyber effects operations, which can result in disruption, denial, degradation, or destr...

The China-linked threat actor known as Jewelbug has been observed carrying out cyber espionage operations targeting governments and militaries, while simultaneously engaging in cryptocurrency fraud. "Both missions are administered from a single control panel, XG-Web , a browser-centric remote-access and information-stealing framework that turns a victim's browser into a full remote-control channel and reaches from there into the host and the internal network behind it," Broadcom's Symantec and Carbon Black Threat Hunter Team said . Jewelbug is assessed to be a China-based hackers-for-hire group that runs parallel operations, including espionage against governments and militaries across the Middle East, Southeast Asia and South Asia, and a for-profit cryptocurrency fraud business. "The group has developed five generations of command-and-control (C&C) code and a family of implants spanning browsers, Windows endpoints, Linux servers and network devices,...

Afghan telecom providers and South Asian critical infrastructure organizations have emerged as the target of a new ongoing campaign that delivers a previously undocumented backdoor called PATCHCORD . According to Acronis Threat Research Unit (TRU) , the backdoor is a compiled C/C++ implant delivered by means of sector-specific lures, including fake VPN installers impersonating Afghan Telecom (AFTEL) and telecom management tools. An analysis of the threat actor's infrastructure has also led to the discovery of another Go-based backdoor dubbed SHEETCORD that uses Google Sheets for command-and-control (C2) communications. The malware has been found to be delivered via a domain impersonating India's National Informatics Center (NIC). "The campaign's infrastructure centers on a single C2 server with multiple associated domains, including domains impersonating Afghan telecom operators and a hijacked legitimate healthcare domain," researchers Darrel Virtusio, San...
