F5 Labs, using attack telemetry from Efflux's global sensor network, analyzed the most exploited vulnerabilities in July 2025 and found that nearly all top-scanned CVEs are HTTP-based RCE or command injection flaws in web interfaces. CVE-2017-9841 (PHPUnit) was the most exploited, followed by CVE-2023-1389 (TP-Link Archer AX21), CVE-2022-…
F5 Labs, using Efflux sensor telemetry, reports a campaign that began on 2025-06-08. One actor is exploiting TP-Link AX21 routers (CVE-2023-1389, command injection in the country query parameter) and Raisecom web interfaces (CVE-2024-7120) to deliver a new malware family named NoBooze1. Four source IPs and three stage-one hosts were rotat…
F5 Labs analyzes CVE-2025-23061 and its predecessor CVE-2024-53900, a CVSS 9.0 flaw in the Mongoose MongoDB client library that allows remote code execution on Node.js API servers. The bug abuses the populate method, which accepts a $where clause containing arbitrary JavaScript. The initial fix for CVE-2024-53900 blocked only top-level $w…
F5 Labs, using Efflux sensor telemetry, reports on the most exploited CVEs of April 2025 and on internet-wide scanning for SparkRAT command-and-control servers. A single actor, using three IPs in DigitalOcean ASN 14061, sent identical HTTP POST requests to the SparkRAT in-place update endpoint, each IP scanning for about 13 hours and reac…
F5 Labs' October AI security roundup describes four incidents, two of which involved no attacker. Coding agents published more than 13,000 internal screenshots to public GitHub repositories (PixelLeak), and a SpaceXAI Grok Bot agent reportedly posted its owner's bank balances to a company Slack channel. The other two involved adversaries …
