5 Critical Security Updates You Need to Know

Stay ahead of the latest security risks with this week’s top cybersecurity highlights and actionable defense steps:

1. Malicious Chrome & Edge Extensions: 19 browser extensions were caught carrying hidden info-stealing code to scrape saved credentials, harvest crypto wallet keys, and trigger "ClickFix" popups.

Action: Audit your browser extensions today. Remove anything unrecognized or no longer actively used.

2. Anthropic Warns of AI Session-Hijacking Infostealer malware on compromised personal PCs is targeting active browser session tokens to hijack private Claude/AI workspaces and drain API limits.

Action: Secure endpoint devices, periodically clear active sessions, and verify endpoint protection is running.

3. The Rise of "TerminalFix" Attacks: An evolution of ClickFix, this tactic tricks users into copying a script to "verify humanity" or "fix a display error" and pasting it into Windows Terminal/PowerShell, instantly executing malware.

 Action: Remind your team: never copy-paste script from a pop-up into a terminal.

4. Microsoft Defender False Notifications: Getting alerts that Defender is turned off after recent updates? Microsoft confirmed this is a false alarm bug; your underlying protection remains active while a patch rolls out.

5. Manchester Airports Group Data Exposure: A recent cyberattack exposed customer booking and travel records.

Action: Watch for hyper-targeted phishing emails posing as airport services asking for password resets or updated payment info.

Stay vigilant, audit your setup, and keep your teams educated on social engineering tactics!
