A recently patched security flaw in Apple macOS has come under active exploitation in the wild to deploy a cryptocurrency miner, the Netherlands National Cyber Security Centre (NCSC) has warned . The vulnerability in question is CVE-2026-65400 (CVSS score: 9.8), a critical authentication issue impacting the Screen Sharing component that could allow an attacker already on the network to authenticate to the built-in remote desktop feature service without valid credentials. The updates released by Apple improve state management mechanisms to enforce correct credential validation and prevent unauthorized authentication attempts. The shortcoming was addressed as part of an emergency update in macOS Tahoe 26.6.1 , macOS Sequoia 15.7.9 , and macOS Sonoma 14.8.9 earlier this month. "An authentication issue was addressed with improved state management," Apple said in an advisory released on August 6, 2026. It credited security researcher Alfredo Pesoli of Bynario for discover...

Threat actors are acquiring expired domains to inherit website traffic and reputation to redirect victims to scams and malware on a large scale. DNS threat intelligence firm Infoblox has given the name dropcatch domains to those that get a second chance, where an expired domain becomes available for registration and is then snapped up by another party. During the first half of 2026, 50,400 dropcatch domains were re-registered each day in the generic top-level domains (gTLDs) like ".com" alone, a figure that jumps to around 65,000 when country code top-level domains (ccTLDs) are taken into consideration. These account for nearly 20$ of all daily gTLD and ccTLD registrations, meaning one out of five newly registered domains is a dropcatch domain. "These domains can be particularly interesting, even dangerous, because they inherit reputation and sometimes connections from their previous life," Infoblox said in an exhaustive three-part report shared with The Ha...

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 within 60 days 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, degrad...

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,...
