🛡️ Stay calm and avoid rash moves when ransomware hits: shutting down systems can cause 'forensic suicide' by destroying volatile evidence such as RAM. Joanna Lang-Recht recommends isolating affected hosts from networks rather than powering them off, preserving forensic images, and engaging specialized incident response teams. Prioritize containment, secure offline backups, and clear crisis roles. Treat negotiation as an economic decision and rely on trained negotiators rather than emotional engagement.

🔒 Rapid7 attributes a late-2025 compromise of the infrastructure hosting Notepad++ to the China-linked actor known as Lotus Blossom. Attackers delivered a previously undocumented backdoor, Chrysalis, via a malicious NSIS installer after hijacking update requests beginning in June 2025; access was terminated on December 2, 2025. Notepad++ patched updater verification in version 8.8.9, migrated hosting, rotated credentials, and responders have published indicators and mitigations.

🐛 A new GlassWorm campaign distributed through compromised OpenVSX extensions is targeting macOS systems to steal passwords, crypto-wallet data, and developer credentials and configurations. Malicious updates pushed from the hijacked oorzc account on January 30 trojanized four packages with roughly 22,000 cumulative downloads and established persistence via a LaunchAgent while excluding Russian-locale systems. Socket's analysis shows broad data collection across browsers, wallets, macOS Keychain, Apple Notes, developer secrets, and exfiltration to 45.32.150[.]251; affected releases were removed and tokens revoked, but users are advised to perform full system clean-up and rotate secrets.

🔍 VirusTotal has identified a surge of malicious OpenClaw skills being used as a delivery channel for droppers, backdoors, infostealers and remote access tools, turning automation workflows into a supply‑chain risk. VT added native support in Code Insight to analyze OpenClaw skill packages (including ZIPs) using Gemini 3 Flash, flagging behaviors like downloading and executing external code, network operations, and sensitive data access. The report highlights prolific abuse by a single publisher and provides concrete recommendations for users and marketplaces to reduce exposure.

⚠️ A security audit by Koi Security found 341 malicious skills among 2,857 listings on the ClawHub marketplace, many deploying a macOS stealer tracked as Atomic Stealer in a campaign dubbed ClawHavoc. Attackers used fake prerequisites and social engineering to trick users into running installers or terminal scripts that fetch next-stage payloads from attacker-controlled infrastructure. The malicious skills include typosquats, crypto tools, YouTube utilities and backdoors that exfiltrate bot credentials and keys, exposing OpenClaw users to significant supply-chain risks.

🔒 A prolific English-language extortion gang calling itself Scattered Lapsus Shiny Hunters (SLSH) combines data theft with coordinated harassment — swatting, DDoS, and call- and email-flooding — to pressure victims into paying. Allison Nixon of Unit 221B and forensic analysis from Mandiant trace recent incidents to early–mid January 2026, when attackers used phone-based phishing to harvest SSO and MFA codes. Nixon warns SLSH is fractious and untrustworthy, and advises organizations that negotiating beyond a firm refusal generally escalates harm and provides attackers information useful for later fraud.

🔒 A months-long supply chain attack redirected update traffic for notepad-plus-plus.org to attacker-controlled servers, enabling malicious manifests to be served to the built-in WinGUp updater and, in some cases, pointing users to compromised executables. Investigators conclude the intrusion stemmed from a compromise of the shared hosting provider infrastructure rather than a flaw in the Notepad++ code. Logs suggest the breach began in June 2025, with direct server access ending on 2 September 2025 while exposed credentials lingered until 2 December 2025.

🔒 Notepad++ developers say Chinese state-sponsored actors hijacked the project's update delivery last year, intercepting and selectively redirecting update requests to malicious servers by exploiting insufficient verification in older WinGUp updaters. The compromise began in June 2025 after a hosting provider breach and persisted until Dec 2, 2025, when the provider terminated access. The project migrated hosting, rotated credentials, patched the updater to verify certificates and signatures, and urges users to change SSH/FTP/MySQL credentials, review WordPress accounts, and update software.

🔒 Have I Been Pwned reports that a January 2026 data breach at Panera Bread exposed roughly 5.1 million unique email addresses and associated contact information, rather than 14 million distinct customers as initially claimed. The files, totaling about 760 MB, were published by the ShinyHunters extortion group after an alleged failed ransom attempt. ShinyHunters says it gained access via a Microsoft Entra SSO code as part of a broader vishing campaign targeting SSO providers. Panera has confirmed the incident to authorities and said the data is contact information.

🔒 CERT-UA reports that Russian-linked group Fancy Bear leveraged CVE-2026-21509 in Microsoft Office to target Ukrainian and EU organizations. Malicious Word documents downloaded a disguised LNK file over WebDAV, which deployed a DLL and an image containing shellcode. The campaign used COM hijacking and a scheduled task to restart explorer.exe and load a malicious EhStoreShell.dll, ultimately launching the Covenant C2 framework. Microsoft has published updates and service-side mitigations; affected customers should apply patches and the recommended registry changes.

🔒 Security researchers at Point Wild’s Lat61 team disclosed a Windows campaign that uses a multi-stage chain to establish persistent, memory-resident access and steal sensitive data. The attack starts with a small batch script that creates a per-user Registry Run key and launches a PowerShell loader which decodes Donut-generated shellcode and injects a heavily obfuscated .NET payload into memory. The modular Pulsar RAT supports live, interactive operator control alongside a parallel stealer, with stolen data exfiltrated as ZIP archives via Discord webhooks and Telegram bots.

⚠️A new report alleges two popular AI coding assistants, together used by roughly 1.5 million developers, are quietly copying everything they ingest to servers in China. Security researchers say the extensions capture editor content, code snippets, and related telemetry without clear user disclosure. The behavior appears systematic and persistent rather than incidental. Until vendors provide transparent remediation, developers and organizations should avoid unvetted extensions and perform immediate audits and containment.

🔒 A new Android remote access trojan (RAT) leverages the AI hosting platform Hugging Face to store and deliver malicious APK payloads, researchers at Bitdefender report. The campaign distributes a dropper app called TrustBastion that uses fake update dialogs to trick users into downloading an updater which redirects to repositories hosting polymorphic RAT APKs. Operators made frequent commits and shifted repositories to avoid takedowns, while the malware requests Accessibility and screen-recording permissions to capture credentials and relay data to command-and-control servers.

🔒 NationStates has confirmed a data breach after taking its browser-based game offline following a player-reported vulnerability that resulted in remote code execution on the production server. The attacker exploited a double-parsing and input sanitization flaw in the Dispatch Search feature to copy application code and user data, including email addresses, MD5 password hashes, login IPs, and browser User-Agent strings. NationStates says telegram contents were likely partially exposed, is wiping and rebuilding the production environment, has reported the incident to authorities, and expects service to be restored within two to five days.

🔒 A former Google engineer, Linwei Ding, was convicted by a US federal jury on 14 counts, including economic espionage and theft of trade secrets, after allegedly exfiltrating over 2,000 pages of sensitive AI technical documents. Prosecutors say he copied data into Apple Notes, converted it to PDFs, and uploaded the materials to a personal Google Cloud account to evade DLP controls. The stolen IP involved custom TPU and GPU orchestration software and SmartNIC designs intended for AI supercomputers, and the DoJ alleges Ding planned to support Chinese state-affiliated entities.

🔐 The maintainer of Notepad++ disclosed that state-sponsored actors compromised the app’s update delivery by hijacking infrastructure at the hosting-provider level, redirecting update traffic to malicious servers. The flaw affected the WinGUp updater’s verification logic, enabling intercepted traffic to fetch poisoned executables. In response, the site has been migrated to a new host and investigations are ongoing.

⚠ MicroWorld Technologies confirmed unknown attackers compromised the update infrastructure for its eScan antivirus and pushed a malicious update that deployed a multi-stage downloader to enterprise and consumer endpoints. The rogue update replaced the legitimate reload.exe with a binary signed by a fake or invalid signature; it executes three Base64-encoded PowerShell stages, includes an AMSI bypass and prevents automatic remediation. Kaspersky and Morphisec report hundreds of attempted infections mainly in India and neighboring countries. MicroWorld isolated affected update servers for hours and released a remediation package; impacted customers should contact the vendor for the fix.

🛡️ On January 30, 2026, threat actors used a compromised developer account to publish malicious updates to four Open VSX extensions, embedding the GlassWorm loader. The extensions — previously legitimate utilities with over 22,000 combined downloads — were removed after discovery. The loader decrypts and execute payloads at runtime, employing EtherHiding and Solana memos for C2 rotation. It targets macOS credentials and cryptocurrency wallets.

🔒 A threat actor is automating data-extortion attacks against publicly exposed MongoDB instances, compromising roughly 1,400 servers and leaving ransom notes demanding about 0.005 BTC (~$500). Researchers at Flare found over 208,500 publicly reachable MongoDB servers, with 3,100 allowing access without authentication and nearly half of those already wiped. There is no guarantee that paying ransoms will restore data or provide working keys. Victims are urged to avoid public exposure, enforce strong authentication, apply network controls, and keep instances updated.

🔒 A U.S. jury has convicted Linwei Ding, a former software engineer at Google, for stealing confidential AI supercomputer information and covertly sharing it with China-based technology firms. Prosecutors say Ding exfiltrated more than 2,000 pages of proprietary material — including details about TPU and GPU systems, orchestration software, and SmartNIC networking — by uploading files to his personal cloud account between May 2022 and April 2023. He later founded Shanghai Zhisuan Technology Co., sought government talent programs, and was convicted on multiple counts of economic espionage and trade secret theft after an 11-day San Francisco trial.
