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…
A Mac user (Reddit u/UntilHEX) reported that Anthropic's Claude Code found an unauthorized XMRig cryptominer while helping build a temperature-monitoring app. Abnormally high sensor readings led the assistant to inspect running processes and identify XMRig as the cause of roughly 1,175% CPU use, or nearly 12 saturated cores. The finding i…
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…
SafeDep reports a growing npm campaign in which forks of Baileys, the WhatsApp Web library for Node.js, abuse the installer's authenticated WhatsApp session to silently follow attacker-controlled channels. Confirmed malicious packages total 82 Baileys-based package names (375 versions) and 15 libsignal-node impersonators (38 versions), ou…
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…
TrustedSec analyzed a multi-stage malware loader that starts as obfuscated Python bytecode (.pyc, CPython 3.13) and ends in an encrypted .NET payload. The chain layers Kramer Python obfuscation, two Donut shellcode layers and a laZzzy shellcode-loader PE, so a signature for any single format misses the others. The author unpacked it with …
Symantec's Threat Hunter Team used an AI honeypot to capture the full instruction set of a malicious autonomous AI agent in summer 2026. The agent is designed to run up to 100,000 malicious actions without human approval: scanning for targets, exploiting vulnerabilities, stealing credentials, deploying cryptocurrency miners and reinfectin…
Bitdefender documented Midnight Mimosa, an Android malware campaign that embeds a platform-signed malicious system app in the firmware of low-cost, MediaTek-based handsets and counterfeit flagship models before they reach buyers. Thousands of infected devices were observed in more than 150 countries over roughly two years. The implant dri…
FortiGuard Labs reports an ongoing Ousaban campaign targeting the Iberian Peninsula. The actor keeps refining its delivery chain and uses geofencing and environmental checks to restrict access to the malware to the intended victims. Ousaban resolves its C2 IP through daily-changing domains and runs a traditional C2 setup as a decoy. Its l…
ClickFix and its variants (FileFix, InstallFix, TerminalFix, ConsentFix) are now the most common browser-based attack technique seen by Push Security. They averaged 52% of Push detections through Q2 2026 and reached 67% in August, overtaking AiTM and device code phishing. The newest lures impersonate AI tools: ANY.RUN linked 1,258 public …
Two beta versions in the @joyfill npm scope, published on July 28, 2026, carried the same blockchain C2 loader seen in the earlier astro.config.mjs attack, which the article ties to the PolinRider campaign. The attacker published through the legitimate scope (a form-builder SDK with three maintainers) under the beta dist-tag. The maliciou…
On August 28, 2026, an attacker published 10 malicious versions of the npm package @7nohe/openapi-react-query-codegen (about 671K downloads/month) without stealing any credentials. They abused the repository's GitHub Actions release.yml workflow, which had an issuecomment trigger with no author-association gate. Commenting npm publish on …
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…
FortiGuard Labs describes a large-scale, global campaign that uses heavily obfuscated JScript droppers to launch an AutoIt/Lua-based loader with low detection rates. The loader delivers several popular RATs and infostealers, including a version of Snake Keylogger. The infection chain relies on business email compromise tactics, impersonat…
Kaspersky found the first documented Android malware targeting automotive head units, discovered in June 2026. It is a multi-stage downloader whose ultimate purpose is ad fraud and a residential proxy botnet. It spread through the built-in updater (TWCore, package com.tw.core) of DoFun head unit firmware, which installs APKs pushed over a…
Unit 42 reports that threat actors are moving supply chain malware C2 from hardcoded endpoints to Web3 mechanisms, so an entire botnet or worm infrastructure can be re-pointed with a single blockchain transaction. The ChainDrop npm worm (Shai-Hulud family, 400+ npm packages) and the PolinRider campaign (npm, Go modules, Packagist) target …
FortiGuard Labs analyzed a TrickBot variant that carries command-and-control (C2) traffic over DNS tunneling, embedding encoded data in DNS queries and responses, instead of the HTTP used by earlier variants. The malware persists through Windows Task Scheduler, stores its configuration in NTFS Alternate Data Streams, and hinders analysis …
Kaspersky GReAT identified an APT campaign in early 2026 targeting diplomatic agencies in Tajikistan, Uzbekistan and Turkmenistan. The attackers used a UEFI bootkit dubbed BlackX, which closely resembles BlackLotus and bypasses Secure Boot by exploiting Baton Drop (CVE-2022-21894). Kaspersky attributes the activity to APT41 with medium co…
The paid WordPress SEO plugin Rank Math PRO was hit by a supply chain attack. Copies of version 3.0.123 downloaded from the vendor's site or delivered as updates between October 15, 2026 20:02 UTC and October 16, 2026 07:12 UTC contained malware (securityweek.com, thehackernews.com, bleepingcomputer.com). Any site that installed and activ…
On August 20, 2026, a compromised release of the Rust crate arrayref (0.3.10, about 245 million all-time downloads) appeared on crates.io. It added a dependency on the typosquatted crate proc-macro1 1.0.107, whose build script downloads and runs a remote binary at compile time. The maintainer account droundy appears to have been compromis…
