F5 Labs published a "canary exploit" generator for CVE-2025-30065, a CVSS 10.0 flaw in the Apache Parquet Java parquet-avro Maven module. The tool lets defenders test whether their environments are vulnerable and confirm that patches and configuration are effective. F5's analysis finds the flaw far less severe than the CVSS score and earl…
F5 Labs published research on SparkRAT, a freely available, Go-based open-source Remote Access Trojan with a C2 server and builds for Windows, Linux and macOS. Public reporting since January 2023 shows use by a widening set of actors: Chinese-speaking groups, Winnti (APT41), Patchwork, TAG-100, suspected UAC-0194 against Ukraine, and Cybe…
F5 Labs honeynet telemetry shows overall hostile activity rising 55.5% month over month in June 2026, a return to the levels of the earlier-year spike. Highlighted is CVE-2024-44000, an unauthenticated account takeover flaw (CVSS 9.8, CWE-522) in the LiteSpeed Cache WordPress plugin, which rose by 1,128 to 2,603 attacks (8). Scanning is i…
F5 Labs reports a scanning campaign observed on its Honeynet in March 2026. It recorded 1,897 session-grouped attempts (2,821 raw events) tied to CVE-2018-14028, a WordPress 4.9.7 unrestricted file upload flaw, and the CVE entered the monthly top 10 after being absent in February. Instead of exploiting the upload flaw, the operator probes…
F5 Labs, using attack telemetry from Efflux sensors, reports that CVE-2017-9841 (PHPUnit eval-stdin.php RCE) remained the most targeted vulnerability in May 2025 with over 54,000 instances. CVE-2020-8958 (Guangzhou ONU command injection RCE) shows near-exponential targeting growth for a third consecutive month. CVE-2024-3721 (TBK DVR OS c…
F5 Labs published its November 2025 AI Security Insights, drawn from the Comprehensive AI Security Index (CASI) and Agentic Resistance Scoring (ARS). Anthropic models took the whole top tier of the CASI leaderboard (Claude Haiku 4.5 at 95.89, Claude Sonnet 4.5 at 95.86, Claude Sonnet 4 at 95.33), while the GPT-5 family slipped, with GPT-5…
The F5 Labs 2026 State of PQC on the Web report scanned the top 1 million domains with TLS 1.3 handshakes. It found that 54% support post-quantum (hybrid) key exchange, but the figure is driven mainly by CDNs, especially Cloudflare and Fastly, which enable PQC by default. Excluding Cloudflare-hosted domains, adoption falls to 22%. Sectors…
F5 Labs, with Efflux sensor telemetry, profiled a persistent information-disclosure scanner operating from 78.153.140.203 in a netblock of AS202306 (HOSTGLOBAL.PLUS LTD), a UK ISP. The IP was first seen on 10 January 2025, vanished on 10 April, and returned on 11 July 2025. It scans 130 unique URLs: 80.23% are variations of /.env, 11.45% …

Other heavily scanned flaws include CVE-2022-24847 (GeoServer), CVE-2022-22947 (Spring Cloud Gateway), CVE-2…
F5 Labs' 2025 Advanced Persistent Bots Report analyzes more than 200 billion web and mobile API transactions from F5 Bot Defense customers between November 2023 and September 2024. It finds that 10.2% (21.22 billion) of requests were bots or automation. Of these, 4.8% were unwanted bots mitigated by F5, 3.5% were flagged automation and 2.…
A Hacktron researcher argues that AI-assisted vulnerability research is rapidly widening the enterprise attack surface. He cites recent breaches at Vercel and GitHub and a wave of critical CVEs in F5, Fortinet, Cisco, Palo Alto and ImageMagick. According to the author, the Vercel compromise began with a breach of the AI platform Context.a…
F5 Labs assesses the security risks and rewards of Chinese open-weight LLMs (Qwen, GLM, Kimi, MiMo, MiniMax, DeepSeek). It finds that strong offensive and defensive cyber capability does not translate into consistent resistance to attack. Cited examples include Kimi K3 finding 19 vulnerabilities in Redis and GLM 5.2 being self-hosted by H…
