A malicious npm package named “indexed-btree” has been observed hiding its malicious behavior within application code rather than using lifecycle scripts, indicating that threat actors are likely shifting tactics in response to recent security controls.

“Indexed-btree is a malicious npm package mimicking the legit sorted-btree package, an ordinary B-tree/indexing utility,” Checkmarx said. “

The threat actor known as SideCopy has been observed using spear-phishing lures to target academic institutions in India, expanding their strategic focus beyond government entities.

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Monday added a now-patched security flaw impacting Zyxel GS1900 series switches to its Known Exploited Vulnerabilities (KEV) catalog, citing evidence of active exploitation.

The vulnerability, tracked as CVE-2026-7273 (CVSS score: 8.8), is a stack-based buffer overflow vulnerability that could result in arbitrary operating

A fake LastPass Authenticator installer offered on GitHub installs a Windows kernel driver that shuts off antivirus and other security software before a password stealer runs if a victim downloads and runs it, researchers at LastPass and Delphos Labs said on September 17.

Microsoft’s own hardware-compatibility program signs the driver, scored zero detections on VirusTotal when researchers
