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…
Palo Alto Networks Unit 42 reviews the current OAuth attack landscape. Attackers are shifting from stealing passwords to stealing OAuth access and refresh tokens, which bypass MFA, survive password resets and give durable access. Unit 42 groups OAuth-based phishing into three categories: account hijacking, permission hijacking and malicio…
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 …
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…
SafeDep found a remote access implant in mathmain, an npm package that copies mathjs, and in two sibling packages, mathsbase and math-universe. The malicious code ships AES-256-GCM encrypted and activates only when lusolve() is called with matrix data whose LU lower factor serializes to a specific password. Once decrypted, the implant tak…
FortiGuard Labs analyzed a SectopRAT variant that is embedded in legitimate software to evade detection. The malware uses a multi-stage loader to extract its payload from files, then applies API hashing, indirect function calls and in-memory loading to run the final .NET payload. Once running, it sets up encrypted communication with its C…
On October 5, 2026, the RubyGems account reqthrottle3474 published 42 malicious gems within about an hour. Most are named for cryptocurrency developer tooling (e.g. eth-keystore-utils, bip39-wordlist-utils, btc-wallet-tools), and the last 16 typosquat real gems (bitcion, etheremu.rb, kecack, solaan-ruby). The code runs during gem install …
Toy Ghouls (aka Bearlyfy, Laboo.boo, Feral Wolf), a financially motivated group targeting Russian organizations since 2025, was observed in early July 2026 using a custom backdoor for the first time. Kaspersky GERT identified two versions, mqtt-bird-agent 0.1.0 (C2 over the public HiveMQ MQTT broker) and matrix-bird-agent 0.1.0 (C2 over a…
On September 8, 2026, an attacker added a malicious source dependency to Deep-Live-Cam, a Python face-swapping app with about 96,600 GitHub stars. Commit 7895c547 ("chore: update requirements.txt") rewrote 18 dependency entries and added requests @ git+https://github.com/pypls/requests.git. This points installation to a lookalike reposito…
ESET documented the evolution of MATCHBOIL, a custom C downloader used by the Russia-aligned cyberespionage group UAC-0099. Samples span April 2024 to April 2026, although CERT-UA first documented the malware in August 2025. Each iteration became more sophisticated, with new obfuscation, sandbox checks and persistence methods. All victims…
Unit 42 (Palo Alto Networks) tracks a campaign, CL-UNK-1211, in which operators compromised government Linux infrastructure between October 2025 and April 2026. The operators used PHP and shell scripts that appear to be AI-generated, with conversational comments and step-by-step reasoning. They harvested credentials and went after databas…
