The U.S. Cybersecurity and Infrastructure Security Agency (CISA) is giving federal agencies until Sunday to patch a vulnerability in Cisco Unified Communications Manager Server that is being actively exploited. [...]

The FBI and CISA have updated their March warning about Russian intelligence phishing Signal accounts, and the operators have added a step: they now coax targets into handing over their Signal Backup Recovery Key. Hand it over once, and the attacker can restore the account's backup, read the private and group message history, and take over the account. Worse, the key keeps working.

Companies are still experimenting with automated AI systems to find security weaknesses, but fewer are relying on the technology.

A newly discovered cyber attack campaign has been observed delivering a previously undocumented malware family called SharkLoader that acts as a loader for deploying Cobalt Strike Beacon on compromised hosts.

A Chinese-speaking advanced persistent threat (APT) actor has been linked to a new custom backdoor called TinyRCT as part of cyber attacks aimed at government entities and critical infrastructure in Southeast Asia. The activity, particularly aimed at state-owned enterprises in the energy and government sectors, has been attributed to a threat actor called CL-STA-1062, which Palo Alto Networks

Instead of eliminating jobs for early-career cyber pros, AI is creating new opportunities for candidates with strong human decision-making skills.

AI won't replace GRC analysts, but it can eliminate much of the repetitive work they do. Anecdotes walks through building an agent that continuously monitors controls, identifies evidence gaps, and opens remediation tasks. [...]

A flaw in the Linux kernel's traffic-control subsystem can let a local unprivileged user gain root on affected systems. CVE-2026-46331, nicknamed "pedit COW," is an out-of-bounds write in the packet-editing action (act_pedit) that corrupts shared page-cache memory. A public, working exploit appeared within a day of the CVE assignment on June 16. Red Hat rates the flaw as

A high-severity flaw in Amazon Q Developer let a malicious repository run commands and steal a developer's cloud credentials. The path was short: a developer opens the repo, trusts the workspace, and Amazon Q does the rest. Amazon has patched it. Tracked as CVE-2026-12957 (CVSS 8.5), the bug sat in how Amazon's AI coding assistant handled Model Context Protocol (MCP) servers. Wiz

AI agents are moving through enterprise environments, inheriting permissions, traversing systems, and executing decisions at machine speed with minimal oversight. The identity infrastructure built to govern human access wasn't designed for autonomous actors, and the gap between what enterprises are deploying and what their governance programs actually cover is widening fast. This guide breaks

Cybersecurity researchers have flagged yet another evolution of the supply chain attack linked to the Mini Shai-Hulud, Miasma, and Hades malware family that has compromised a new set of npm packages, even as it has propagated to the Go ecosystem. "The latest activity includes malicious npm releases affecting LeoPlatform and RStreams packages, GitHub Actions workflow abuse, and a related Go

An active phishing campaign has been targeting hotel and other hospitality organizations across Europe and Asia since April 2026, using photo-themed ZIP files to drop a Node.js implant and dig into front-desk machines, Microsoft says.
