A sophisticated China-nexus advanced persistent threat (APT) group has been attributed to attacks targeting government entities in South America since at least late 2024 and government agencies in southeastern Europe in 2025. The activity is being tracked by Cisco Talos under the moniker UAT-8302, with post-exploitation involving the deployment of custom-made malware families that have been put from The Hacker News https://thehackernews.com/2026/05/china-linked-uat-8302-targets.html

Cybercriminals are getting smarter and faster. Social engineering attacks are evolving rapidly, and AI is making them more convincing than ever.

DarkSword is a sophisticated piece of malware —probably government designed—that targets iOS. Google Threat Intelligence Group (GTIG) has identified a new iOS full-chain exploit that leveraged multiple zero-day vulnerabilities to fully compromise devices. Based on toolmarks in recovered payloads, we believe the exploit chain to be called DarkSword. Since at least November 2025, GTIG has observed multiple commercial surveillance vendors and suspected state-sponsored actors utilizing DarkSword in distinct campaigns. These threat actors have deployed the exploit chain against targets in Saudi Arabia, Turkey, Malaysia, and Ukraine. DarkSword supports iOS versions 18.4 through 18.7 and utilizes six different vulnerabilities to deploy final-stage payloads. GTIG has identified three distinct malware families deployed following a successful DarkSword compromise: GHOSTBLADE, GHOSTKNIFE, and GHOSTSABER. The proliferation of this single exploit chain across disparate threat actors mi...

An active phishing campaign has been observed targeting multiple vectors since at least April 2025, with legitimate Remote Monitoring and Management (RMM) software as a way to establish persistent remote access to compromised hosts. The activity, codenamed VENOMOUS#HELPER, has impacted over 80 organizations, most of which are in the U.S., according to Securonix. It shares overlaps with clusters from The Hacker News https://thehackernews.com/2026/05/phishing-campaign-hits-80-orgs-using.html
