CISA orders federal agencies to patch CVE-2026-32202 after zero-click NTLM hash leak is reported
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has ordered federal agencies to secure Windows systems against a vulnerability tracked as CVE-2026-32202 after cybersecurity firm Akamai reported it as a zero-click NTLM hash leak left behind when Microsoft incompletely patched a February remote code execution flaw (CVE-2026-21510). CISA added CVE-2026-32202 to its Known Exploited Vulnerabilities (KEV) Catalog and mandated that
Pastebin-Hosted PowerShell Script Hijacks Telegram Sessions: What Happened and How to Respond
Security researchers recently uncovered a PowerShell script posted on Pastebin that was purpose-built to steal Telegram session data from both desktop and web clients. Masquerading as a benign “Windows Telemetry Update,” the script quietly collects host metadata, locates Telegram session stores, compresses them into an archive, and exfiltrates the file to an attacker-controlled Telegram bot. The discovery is notable less
CISA: Zimbra XSS (CVE-2025-48700) Now Exploited — 10,500+ Servers Vulnerable
Over 10,000 instances of the Zimbra Collaboration Suite are exposed online and remain vulnerable to an actively exploited cross-site scripting flaw, raising fresh alarms about email server security for governments and businesses alike. The vulnerability, tracked as CVE-2025-48700, is serious because it can be triggered without user interaction and has been confirmed as abused in the wild, prompting action from
Hackers Leverage Microsoft Teams to Breach Organizations: Inside UNC6692’s SNOW Campaign
In late 2025 and into early 2026, a sophisticated intrusion campaign used the everyday familiarity of Microsoft Teams to turn routine collaboration into a direct route for enterprise compromise. By posing as IT helpdesk staff and exploiting users’ trust in external Teams invitations, the threat group tracked as UNC6692 moved from a simple chat message to full domain-level access—without exploiting
