ACR Stealer, an infostealer in circulation since 2024, is walking out of enterprise networks with saved browser passwords, live session tokens, PDFs, Microsoft 365 documents, and files from synced OneDrive and SharePoint folders. It gets in because someone pasted a command into a Run box and pressed Enter. Microsoft laid out two of the delivery chains on Thursday. Its Defender Experts team, the

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Thursday added a newly patched security flaw impacting Microsoft SharePoint Server to its Known Exploited Vulnerabilities (KEV) catalog, requiring Federal Civilian Executive Branch (FCEB) agencies to apply the fixes by July 19, 2026. The vulnerability in question is CVE-2026-58644 (CVSS score: 9.8), a critical deserialization

Owen Flowers, 18, and Thalha Jubair, 20, were each sentenced to five and a half years at Woolwich Crown Court on Thursday, 16 July 2026, for the 2024 hack of Transport for London. The attack left 148 TfL systems inoperable and forced all 27,000 of the transport authority's employees into an office to get their passwords reset in person. Both the NCA and the CPS put TfL's losses and recovery

A lot of this week’s trouble starts with something that looks close enough. A familiar repo. A useful installer. A harmless sync setting. Then the handoff goes bad, the box starts talking to someone else, and the damage moves faster than the explanation. Old bugs are back, weak defaults are earning their keep, and some attack paths are so plain they barely feel like research. Here’s the mess.

n8n, the workflow automation platform, handed out the wrong accounts at login. On Enterprise instances configured to trust more than one external token issuer, it matched an incoming JWT to a local user on the sub claim alone and ignored iss. A valid token from issuer A carrying a sub that belongs to someone under issuer B logged you in as them. Their password never

ClickLock Stealer, a new macOS infostealer, answers a victim's refusal by killing their apps on a loop until they hand over the login password. It arrives as a command pasted into Terminal, asks for the password behind a fake system dialog, and when the victim cancels, installs two LaunchAgents and quietly exits. At the next login, Finder, the Dock, Spotlight, Terminal, Activity Monitor, and

Cybersecurity researchers have called attention to a new modular malware called TELEPUZ that's been spreading via websites infected with ClickFix lures since late April 2026. "The malware is full-featured, lightweight, and modular," Elastic Security Labs researcher Cyril François said in a technical report. "While the number of C2 [command-and-control] domains is currently small, the daily
