⚠ Multiple security vendors report a second Sha1-Hulud campaign that has trojanized hundreds of npm packages and affected over 25,000 repositories. The attack leverages a preinstall script ("setup_bun.js") to install or locate the Bun runtime and execute a bundled payload ("bun_environment.js") that harvests credentials. The malware registers hosts as self-hosted GitHub runners named "SHA1HULUD", drops a vulnerable workflow (.github/workflows/discussion.yaml) to run arbitrary commands via repository discussions, exfiltrates secrets as artifacts, and then removes traces; when exfiltration fails it can attempt destructive wiping of the user home directory.

🔒Operation Endgame 3.0, coordinated by Europol with over 30 national and private partners, dismantled more than 1,000 servers and seized 20 domains tied to the Rhadamanthys infostealer, VenomRAT and the Elysium botnet. Authorities say the disrupted infrastructure harboured hundreds of thousands of infected computers and millions of stolen credentials, with the Rhadamanthys operator allegedly accessing over 100,000 crypto wallets. The action included 11 searches and at least one arrest; users are advised to check accounts via national breach-check services or HaveIBeenPwned and to maintain strong defences as criminals can rebuild.

⚠️ Acronis Threat Research Unit (TRU) reports an ongoing global malvertising campaign, dubbed TamperedChef, that employs counterfeit installers masquerading as popular utilities and product manuals to deploy an information-stealer and obfuscated JavaScript backdoors. Operators use SEO poisoning, malicious ads, and abused code-signing certificates from shell companies in the U.S., Panama, and Malaysia to increase trust and evade detection. Installers drop an XML file to create a scheduled task that launches the JavaScript backdoor, which exfiltrates encrypted, Base64-encoded JSON over HTTPS. Infections concentrate in the U.S. and have also been observed in Israel, Spain, Germany, India, and Ireland, with healthcare, construction, and manufacturing among the most affected sectors.

📲 Trustwave SpiderLabs describes a Python-based WhatsApp worm that propagates a Delphi credential stealer named Eternidade Stealer across Brazilian devices. The campaign begins with an obfuscated Visual Basic Script dropper that installs both a Python WPPConnect-based propagator and an MSI/AutoIt installer which injects the stealer into svchost.exe. Operators use IMAP to fetch dynamic C2 addresses and apply Brazilian Portuguese geofencing to limit infections to the target region.

🔒 Trustwave SpiderLabs has identified Eternidade Stealer, a multi-component banking Trojan that combines a Python-based WhatsApp-propagating worm, a Delphi stealer and an MSI dropper to harvest financial credentials and spread laterally. The campaign uses an obfuscated VBScript to deliver two payloads, dynamically retrieves command-and-control via IMAP and activates only on systems using Brazilian Portuguese. Defenders should watch for unexpected MSI or script executions, suspicious WhatsApp messages and indicators linked to the campaign.

🔎 The Contagious Interview campaign is delivering trojanized coding tests that fetch heavily obfuscated JavaScript from public JSON-storage services such as JSON Keeper, JSONSilo, and npoint.io. When executed in a Node.js test run the payloads decode and install the BeaverTail infostealer and then stage the InvisibleFerret RAT. NVISO Labs warns attackers are abusing developer trust and legitimate platforms and recommends sandboxing, auditing config files, and blocking suspicious outbound requests.

🔒 A malicious Chrome extension posing as Safery: Ethereum Wallet was found to exfiltrate Ethereum wallet seed phrases by encoding mnemonics into synthetic Sui addresses. Socket security researcher Kirill Boychenko and Koi Security report the extension broadcasts micro-transactions (0.000001 SUI) from an attacker-controlled wallet to smuggle seed phrases on-chain without a traditional C2 server. Uploaded on September 29, 2025 and updated November 12, it remained available at the time of reporting. Users should stick to trusted wallet extensions and defenders should flag unexpected RPC calls and on-chain writes during wallet import or creation.

🛡️ Investigators disrupted the infrastructure for the Rhadamanthys credential stealer and targeted the VenomRAT remote‑access trojan as part of Operation Endgame. Authorities secured data linked to more than 650,000 victims and published it on information platforms so people can verify exposure. A suspect was arrested in Greece, 11 premises were searched and over $200 million in cryptocurrency assets were frozen.

🛡️ A coordinated law enforcement operation led by Europol and Eurojust between November 10–13, 2025 disrupted major malware infrastructures, including Rhadamanthys Stealer, Venom RAT, and an Elysium botnet. Authorities seized 20 domains, took down more than 1,025 servers and arrested a primary suspect in Greece on November 3. Europol said the dismantled networks encompassed hundreds of thousands of infected machines and several million stolen credentials, and that the infostealer operator had access to roughly 100,000 cryptocurrency wallets.

🔒 Law enforcement from nine countries disrupted infrastructure used by the Rhadamanthys infostealer, VenomRAT remote access trojan and the Elysium botnet during a phase of Operation Endgame. Coordinated by Europol and Eurojust with private partners, officers seized 20 domains, took down 1,025 servers and executed searches at 11 locations between 10 and 14 November 2025. A key suspect linked to VenomRAT was arrested in Greece, and authorities warn that the dismantled infrastructure contained hundreds of thousands of infected machines and several million stolen credentials, plus access to over 100,000 crypto wallets.

🔒 The Rhadamanthys infostealer operation has reportedly been disrupted, with multiple customers saying they no longer have SSH access to their web panels. Affected users report servers now require certificate-based logins instead of root passwords, prompting some to wipe and power down infrastructure. Researchers g0njxa and Gi7w0rm observed the outage and noted Tor onion sites for the operation are also offline. The developer and several customers suspect German law enforcement, and some analysts link the event to the broader Operation Endgame disruptions.

⚠️ Threat hunters report a .NET banking trojan dubbed Maverick propagating via WhatsApp Web, with analyses noting significant code overlaps with the Coyote family and attribution to the actor known as Water Saci. The campaign uses a self-propagating component named SORVEPOTEL to distribute a ZIP containing an LNK that launches PowerShell/cmd to fetch loaders from zapgrande[.]com. The loader installs modules only after geo/linguistic checks confirm the victim is in Brazil and then deploys banking-targeted credential-stealing and web-injection capabilities.

🔒 Researchers identified three malicious VS Code extensions tied to the GlassWorm campaign that together had thousands of installs. The packages — ai-driven-dev.ai-driven-dev, adhamu.history-in-sublime-merge, and yasuyuky.transient-emacs — were still available at reporting. Koi Security warns GlassWorm harvests Open VSX, GitHub, and Git credentials, abuses invisible Unicode for obfuscation, and uses blockchain-updated C2 endpoints. Defenders should audit extensions, rotate exposed tokens and credentials, and monitor repositories and wallet activity for signs of compromise.

⚠ The GlassWorm malware campaign has resurfaced on OpenVSX, delivering malicious payloads via three new VSCode extensions that have been reported as downloaded over 10,000 times. The extensions use invisible Unicode obfuscation to execute JavaScript and harvest credentials and cryptocurrency wallet data through Solana transactions. Koi Security says the attacker reused infrastructure with updated C2 endpoints and that investigators accessed an attacker server, recovering victim data and identifying multiple global victims.

⚠️ Researchers flagged a malicious Visual Studio Code extension named susvsex that auto-zips, uploads and encrypts files on first launch and uses GitHub as a command-and-control channel. Uploaded on November 5, 2025 and removed from Microsoft's VS Code Marketplace the next day, the package embeds GitHub access tokens and writes execution results back to a repository. Separately, Datadog disclosed 17 trojanized npm packages that deploy the Vidar infostealer via postinstall scripts.

🔒 Datadog Security researchers found 17 npm packages (23 releases) that used a postinstall downloader to execute the Vidar infostealer on Windows systems. The trojanized modules masqueraded as Telegram bot helpers, icon libraries, and forks of libraries like Cursor and React, and were available for about two weeks with at least 2,240 downloads before the accounts were banned. Organizations should adopt SBOMs, SCA, internal registries, add ignore-scripts policies, and enable real-time package scanning to reduce supply chain risk.

🔒 Cybersecurity researchers CYFIRMA and independent analyst F6 have disclosed two active Android trojans—BankBot‑YNRK and DeliveryRAT—that harvest financial and device data from compromised phones. BankBot‑YNRK impersonates an Indonesian government app, performs device fingerprinting and anti-emulation checks, abuses accessibility services to steal credentials and automate transactions, and communicates with a command server. DeliveryRAT, promoted via a Telegram bot, lures Russian users with fake delivery and marketplace apps and delivers malware-as-a-service variants that collect notifications, SMS and call logs and can hide their launchers. Users should avoid untrusted APKs, review permissions, and keep devices updated—Android 14 reduces some accessibility-based abuses.

🔒 Russian authorities have arrested three individuals in Moscow accused of creating and operating the Meduza information‑stealing malware. Announced on Telegram by police general Irina Volk, investigators say the group developed and distributed Meduza via hacker forums around two years ago and offered it as a subscription-based service. The tool steals browser-stored credentials and cryptocurrency data and, since December 2023, can resurrect expired Chrome authentication cookies to facilitate account takeover. Authorities opened a criminal case after operators targeted an Astrakhan institution and seized confidential server data.

🚨 A multi-stage supply-chain campaign published ten typosquatted npm packages on July 4 that collectively reached nearly 10,000 downloads before removal, according to Socket. Each package abused npm’s postinstall lifecycle to open a new terminal, present a fake CAPTCHA prompt, and retrieve a PyInstaller-packed binary that harvests credentials from browsers, OS keyrings, SSH keys, tokens and cloud configuration files. The JavaScript installers combined four layers of obfuscation with social engineering to evade detection and delay scrutiny while exfiltrating collected secrets to the attacker’s host.

⚠️ Koi Security has identified a supply-chain campaign dubbed PhantomRaven that inserted malicious code into 126 npm packages, collectively installed more than 86,000 times, by pointing dependencies to an attacker-controlled host (packages.storeartifact[.]com). The packages include preinstall lifecycle hooks that fetch and execute remote dynamic dependencies, enabling immediate execution on developers' machines. The payloads are designed to harvest GitHub tokens, CI/CD secrets, developer emails and system fingerprints, and exfiltrate the results, while typical scanners and dependency analyzers miss the remote dependencies because npmjs.com does not follow those external URLs.
