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, 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 that CVE-2023-1389, an RCE in TP-Link Archer AX21 routers, was the most scanned-for CVE in December 2024 for the fifth consecutive month, with traffic far above any other tracked CVE. Other heavily scanned flaws include CVE-2022-24847 (GeoServer), CVE-2022-22947 (Spring Cloud Gateway), CVE-2…
F5 Labs' January 2026 AI security roundup covers two attack developments: the Persona Bullying jailbreak and a critical LangChain serialization injection vulnerability (CVE-2025-68664) reachable through prompt injection. Persona Bullying applies human social-engineering tactics such as gaslighting, ridicule and social pressure to LLMs con…
CVE-2026-9082 is a critical (CVSS 9.8) pre-authentication SQL injection in the JSON:API module of Drupal Core. It was published on May 20, 2026 and added to the CISA KEV catalog the same month, with a remediation deadline of May 27. F5 sensors recorded 576 exploitation attempts from 9 source IPs between May 20 and May 31, 2026. The earlie…
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 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…
Hacktron AI researchers disclosed CVE-2026-33439 (CVSS 9.8, CWE-502), an unauthenticated remote code execution flaw in OpenIdentityPlatform OpenAM 16.0.5 and earlier. It is a variant of CVE-2021-35464: the earlier fix whitelisted deserialization for the jato.pageSession parameter but left the sibling jato.clientSession parameter unfiltere…
Researchers at Hacktron (author ginoah) described five bypasses of the Vercel WAF rules protecting against React2Shell (CVE-2025-55182), a pre-auth RCE in React Server Functions affecting Next.js 15.x–16.0.6 and other React-based frameworks. The bypasses were found during a Vercel bounty challenge. Per Vercel's writeup, 116 researchers to…
Sekoia observed an attacker interacting with an exposed Flowise AI orchestration honeypot (emulating version 2.2.8) in late August 2026. The operator enumerated chatflows and stored credentials, tried to create a rogue workflow, and used prompt injection to turn the agent into an offensive analysis assistant. Sekoia assesses the activity …
GreyNoise observed automated scanners impersonating the web crawlers of OpenAI, Anthropic, Google, Perplexity, DeepSeek and Amazon while requesting environment files, cloud access keys, private keys and password stores. A cluster of 13 forged AI crawler names from eight companies was seen; six names (belonging to Anthropic, OpenAI, Google…
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% …
Kaspersky's Q2 2026 vulnerability landscape report records an unprecedented number of registered CVEs, including critical ones. It attributes the surge mainly to AI-assisted vulnerability discovery and AI-generated code. Researchers are also publishing exploits for unpatched flaws more often. One example is Nightmare Eclipse (Chaotic Ecli…
In late August 2026, Sekoia's TDR team observed an attacker compromise an unauthenticated Flowise honeypot (emulating v2.2.8). The attacker harvested stored credentials, tried to plant a malicious chatflow with a callback to 154.217.251.226, and used prompt injection to turn the LLM agent into an offensive analysis assistant. The activity…
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…
FortiGuard Labs describes Evooo1Bot, a Linux botnet that embeds the Mirai DDoS engine in a more modular and capable framework. It uses encrypted C2 communications, layered string obfuscation (AES-256-CTR, ChaCha20, XOR-based key derivation) and a 28-command remote administration interface. It also ships an integrated exploit arsenal again…
