Vulnerabilities
Ubiquiti has patched three maximum-severity flaws in UniFi OS — the operating system behind its gateways, Dream Machines, and network video recorders. All three are rated CVSS 10.0, and all three are remotely exploitable by an attacker with no privileges.
Vulnerabilities
Trend Micro's own Incident Response team discovered CVE-2026-34926, a directory-traversal zero-day in Apex One, while it was being exploited. CISA added it to the KEV catalog with a June 4 federal deadline. Its modest 6.7 CVSS score conceals an environment-wide blast radius.
Supply Chain Attack
An automated campaign called Megalodon pushed 5,718 malicious commits to 5,561 GitHub repositories in six hours, hiding secret-stealing payloads inside CI/CD workflow files. It weaponizes the merge — the most routine action in software development.
Data Breaches
Trump Mobile confirmed customer names, email and mailing addresses, phone numbers, and order identifiers were exposed to the open internet via a third-party platform provider, and said it is still evaluating whether it must notify affected customers.
Nation-State Cyber Threats
Palo Alto Networks' Unit 42 is tracking Screening Serpens, an Iran-nexus APT that fuses DLL sideloading with AppDomainManager hijacking to make .NET applications switch off their own security mechanisms, then deploys six new RATs across the U.S., Israel, and the UAE.

Cybersecurity 101
A complete guide to the major types of cyberattacks — from malware and phishing to injection, credential, and AI-enabled attacks — and how to defend against each.
Vulnerabilities

Policy & Government
A Europol- and Eurojust-coordinated operation dismantled First VPN — a service Europol calls the most widely used in the cybercrime underground — arresting an admin, seizing 33 servers, and identifying thousands of cybercrime-linked users. The intelligence yield is the story.
Nation-State Cyber Threats
Lumen's Black Lotus Labs disclosed Showboat, a modular Linux backdoor a China-affiliated espionage operation has used to sit inside Middle East and Central Asia telecom networks for roughly four years. A SOCKS5-proxy foothold inside a carrier is a persistent window into a region's traffic.
