Check Point Exposure Management researchers identified a campaign that mass-produces fraudulent customer support PDFs and posts impersonating more than 20 travel brands, including airlines, travel agencies and transportation companies. The documents are uploaded to trusted university, government and commercial websites through public uplo…
Unit 42 analyzed the operational environment of a previously unreported, financially motivated, English-speaking actor using the handle BUGSTER. The actor ran the Hermes Agent framework with DeepSeek V4 as its reasoning engine and the Cursor IDE as a secondary tool, with safety controls disabled in both. With AI-generated scripts and reco…
Check Point Research reports that commercial antidetect browsers, notably Kameleo, AdsPower and MultiLogin, are widely referenced on Russian-language underground forums and marketplaces. They are used for account takeover, payment card fraud (carding), fraudulent loan applications, ad-revenue fraud, bulk creation of fake accounts and coor…
Israeli startup Hirundo reports that Alibaba's Qwen3-Coder shows a pro-CCP bias, producing more vulnerable code when asked to build applications for Western organizations. This is consistent with earlier findings by CrowdStrike (November 2025) and Booz Allen Hamilton (May 2026). Hirundo had the model build web services (sign-up, login, se…
A Flare analysis argues that Scattered Spider, LAPSUS$ and ShinyHunters are distinct intrusion clusters within The Com, a decentralized, mostly English-speaking cybercriminal subculture, and not interchangeable names for one group. It describes SP1D3R HUNTERS (also called Scattered LAPSUS$ Hunters, SLH) as a shared brand and coordination …
Objective-See analyzed Heartbreaker, a previously unknown macOS ransomware sample (ad hoc-signed ARM64 Mach-O written in Rust). It was uploaded to VirusTotal in May 2025 and remains undetected by all AV engines. It was found by researcher Megan Carney. It encrypts files in ~/Downloads with AES-256-GCM, renames them to .heartbreaker, drops…
Flashpoint's first monthly insider threat report, drawn from its Primary Source Collection (PSC), identified 9,787 insider-related posts across 1,216 channels and 1,778 authors in September 2026. Overall volume fell, but threat actors kept recruiting insiders and advertising insider access, mostly to enable fraud. Flashpoint counted 857 u…
Infoblox attributes the long-running Help TDS traffic distribution system, active since at least April 2017, to Hotejka, a small Russian-language affiliate program that appears to be a rebrand of ROI777 (exposed in 2018). The TDS fingerprints visitors and redirects them to browser-lock tech support scams that push victims to call centers,…
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…
Since mid-2025 the Kremlin has sharply escalated restrictions on digital communications, according to Insikt Group (Recorded Future). Measures include VPN blocking, state-managed regional internet shutdowns, throttling of Telegram and WhatsApp, promotion of the state-owned Max messenger, and expanded surveillance of Russian and foreign en…
TrustedSec researcher Lilly Mayo published waf-fu, an offensive tool that pulls AWS WAF log data into a local sqlite database and enables replay of logged requests. During an engagement, the author found WAF logs in CloudWatch that captured all headers unredacted, including session cookies and other authentication material, which can be r…
Between May 9 and May 18, 2026, GreyNoise observed a major spike in scanning of SonicWall SonicOS management interfaces. The May 12 peak of about 597,000 sessions was the largest single-day total on the SonicWall SonicOS API Scanner tag in 90 days, roughly 46x the typical daily volume. Earlier spikes on this tag (January 18, January 30 an…
GreyNoise analyzed 147.8 million sessions over 103 days across 276 vendor-specific tags covering 18 network infrastructure vendors. It found that surges in scanning and exploitation activity regularly precede vendor advisories. Of 104 detected surges, 68 preceded a vendor-matched CVE (33 vulnerabilities across 16 vendor families), with a …
GreyNoise reports that 21 IP addresses in AS213438 (registered to ColocaTel Inc., Mahe, Seychelles) produced 1,856,167 of 2,753,274 global RDP Crawler sessions on April 7, 2026, or 67.4% of the worldwide total. Over April 5-7 the same fleet accounted for 49.7% of global RDP Crawler activity. All 21 IPs are geolocated to the Netherlands, w…
GreyNoise analyzed 4 billion sessions targeting edge infrastructure over 90 days and concluded that IP reputation feeds are structurally ineffective against residential proxy traffic. Attackers route scanning and reconnaissance through compromised home broadband, mobile and small-business connections, so source IPs look like legitimate us…
Between March 12 and 18, 2026, the GreyNoise Observation Grid (GOG) recorded 242,666 new scanning IPs geolocating to Hong Kong, 48.9% of all new scanning IPs seen that week. 99.7% never completed a TCP handshake, so GreyNoise classes them as "spoofable" (unverified source addresses). They carried no payloads and triggered no signatures. G…
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…
Researchers at Hacktron disclosed a vulnerability chain in Cluely, an Electron-based AI assistant that reads the user's screen and microphone. They found it in July 2025 and published in February 2026. The main window had no will-navigate handler, so a link in the AI's markdown response could navigate the whole app to an attacker-controll…
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…
SmartLoader is a commodity loader in active deployment, attributed to Malware-as-a-Service infrastructure linked to LummaStealer delivery in recent campaigns. Reverse engineering shows it is built almost entirely from off-the-shelf parts: a stock signed LuaJIT 2.1.0-beta3 interpreter, a commercial Lua VM obfuscator from the game-cheat sce…
