🔐 Researchers at Flare Systems uncovered a botnet, dubbed SSHStalker, that brute-forces weak SSH passwords and had compromised an estimated 7,000 Linux servers by the end of January, with roughly half located in the United States. The toolkit combines fileless malware, rootkits, log cleaners and a library of kernel exploits — some dating to 2009 — and can harvest AWS credentials. Flare characterizes it as a "scale-first" operation focused on persistence; observed capabilities include DDoS and cryptomining, though monetization has not yet been seen. Immediate mitigations include disabling SSH password authentication, switching to key-based or short-lived credentials, and restricting and rate-limiting SSH access.

🛡️ UNC1069, a North Korea-linked threat actor, has used AI-generated video lures and compromised Telegram accounts to target cryptocurrency firms and personnel. According to Google Mandiant, attackers staged fake Zoom meetings via Calendly invites and delivered a ClickFix-style troubleshooting vector that dropped multiple payloads on Windows and macOS. The intrusion employed at least seven malware families — including WAVESHAPER, HYPERCALL, HIDDENCALL, DEEPBREATH, CHROMEPUSH and SILENCELIFT — to harvest credentials, browser data and session tokens to facilitate financial theft.

🔒 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.

🛡️ 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.

🛡️Infostealer-laden Roblox “mods” and gaming downloads are a growing initial-access vector, commonly distributed through YouTube videos, Discord invites, GitHub repos, and cloud links. Within seconds these malicious executables harvest browser-saved passwords, session cookies, OAuth tokens, VPN credentials, SSH keys, and crypto wallets. Victims often run them on family or home PCs, enabling attackers to acquire corporate SSO access, bypass MFA with valid tokens, and move laterally. Identity compromise — not software exploits — is the primary enterprise threat.

⚠️ Trend Micro detailed a campaign using a new information stealer, Evelyn Stealer, that abuses the Visual Studio Code extension ecosystem to harvest developer secrets. Malicious extensions drop a downloader DLL (Lightshot.dll) which launches a staged executable (runtime.exe) and injects the stealer into a legitimate process (grpconv.exe) to run in memory. The malware collects credentials, cookies, crypto wallets, screenshots, Wi‑Fi data and system metadata, then exfiltrates compressed archives to an attacker-controlled FTP server.

🔓 Mandiant released a pre-computed Net-NTLMv1 rainbow table so anyone can map challenge-response data back to real NT hashes, a move intended to force organizations to abandon the insecure NTLMv1 protocol. The dataset, hosted via the Google Cloud Research Dataset portal, can recover keys in about 12 hours using roughly $600 of hardware. Mandiant says the goal is to demonstrate immediate risk and prompt remediation rather than to create new vulnerabilities.

🔎 Ukrainian and German law enforcement raided residences in Lviv and Ivano‑Frankivsk on 15 January, seizing digital storage devices and cryptocurrency assets linked to two suspected members of the Black Basta ransomware group. Investigators say the men acted as 'hash crackers,' extracting passwords to escalate access, steal data and deploy ransomware across corporate networks. The operation involved the Ukrainian National Police and Germany's BKA and formed part of a wider international probe coordinated by Europol. Authorities also identified alleged founder Oleg Evgenievich Nefedov, who has been placed on Europol’s EU Most Wanted and Interpol Red Notice lists.

🔐 Mandiant and Google Cloud published a comprehensive dataset of Net-NTLMv1 rainbow tables to accelerate defender validation and mitigation of this long-deprecated protocol. The tables make known-plaintext attacks trivial, enabling recovery of authenticating password hashes in under 12 hours on consumer hardware costing less than $600. The release includes SHA512 checksums, usage guidance with tools like rainbowcrack and ntlmv1-multi, and prescriptive remediation steps to disable Net-NTLMv1 and monitor for coercion-based authentications.

🚨A cybercrime gang known as Black Cat has been linked to an SEO poisoning campaign that tricks users with fake download pages for popular programs such as Google Chrome and Notepad++. Visitors are redirected to a GitHub‑mimicking host where a ZIP delivers an installer that creates a desktop shortcut which side‑loads a malicious DLL and deploys a backdoor. The backdoor contacts a hard‑coded C2 and can steal browser data, log keystrokes and capture clipboard contents. Users should avoid clicking unknown search results and download software only from official sources.

🔒 Blockchain investigator TRM Labs says a series of cryptocurrency thefts were traced back to the 2022 LastPass breach, where encrypted vault backups containing private keys and seed phrases were stolen. Attackers appear to have slowly decrypted vaults for users with weak or reused master passwords, draining wallets in waves months or years later. TRM also reported that stolen funds were converted to Bitcoin and laundered through Wasabi Wallet CoinJoin mixes before cash‑out via Russian-linked exchanges.

🚨 The fourth wave of the GlassWorm campaign is targeting macOS developers by distributing malicious VS Code/OpenVSX extensions that deliver trojanized cryptocurrency wallet applications. The extensions embed an AES-256-CBC-encrypted payload in compiled JavaScript, execute after a 15-minute delay using AppleScript, and persist via LaunchAgents. The malware harvests developer credentials, browser and Keychain data, supports VNC and SOCKS proxying, and includes a mechanism to replace Ledger Live and Trezor Suite with trojanized versions. Users should remove the identified extensions, reset credentials, revoke tokens, and inspect or reinstall affected macOS systems.

🔒 Cybersecurity researchers detailed a five-month, targeted spear-phishing campaign that published 27 malicious npm packages across six aliases to repurpose package CDNs as resilient hosting for browser‑run credential‑harvesting lures. The embedded HTML/JavaScript mimicked document‑sharing portals and Microsoft sign‑in, pre-filling victim emails and using bot/sandbox checks, honeypot fields and heavy obfuscation to evade detection. Socket links the domains to Evilginx-style AitM infrastructure and urges phishing‑resistant MFA, strict dependency verification, CDN request logging, and monitoring for suspicious post‑auth activity.

🔒 Researchers warn that the React2Shell flaw (CVE-2025-55182) is being actively exploited to deploy sophisticated Linux backdoors and harvest credentials. Palo Alto Networks Unit 42 and NTT Security report active use of KSwapDoor and ZnDoor, which provide interactive shells, file operations, lateral scanning, and stealthy mesh networking. Attackers are also abusing Cloudflare Tunnels and secret-scraping tools to extract cloud and AI tokens. Organizations should prioritize discovery, credential rotation, and removal of dropped backdoors and follow vendor mitigations immediately.

🔒 Askul Corporation confirmed that the RansomHouse extortion group stole approximately 740,000 customer and partner records during an October ransomware incident. Compromised data types include business and individual customer service records, partner data, and employee information. Askul says attackers likely used compromised administrator credentials for an outsourced partner that lacked MFA, disabled EDR, moved laterally, deployed multiple ransomware variants, and wiped backups. The company has isolated affected networks, enforced MFA, reset admin passwords, begun individual notifications and established long-term monitoring.

🔒 Chinese state-sponsored actors are implanting a Go-based backdoor called BRICKSTORM on VMware vCenter and ESXi servers to maintain long-term persistence in targeted networks. CISA, NSA and the Canadian Cyber Centre analyzed multiple samples and found the malware often remained undetected for extended periods, enabling lateral movement, credential theft and exfiltration via VSOCK and SOCKS5 proxy functionality. The joint advisory includes IOCs, YARA and Sigma rules and recommends patching, hardening vSphere, restricting service account privileges, segmenting networks and blocking unauthorized DoH.

🔒 ESET reports Iranian-aligned MuddyWater has deployed a previously undocumented backdoor named MuddyViper against Israeli organizations across academia, engineering, local government, manufacturing, technology, transportation, and utilities, as well as one Egyptian technology company. The intrusions began with spear-phishing PDFs and exploitation of VPN and remote-access vulnerabilities to deliver loaders called Fooder, which decrypt and execute the C/C++ backdoor or drop tunneling proxies and browser-data collectors. MuddyViper implements about 20 commands for reconnaissance, file transfer, command execution, and exfiltration of Windows credentials and browser data; several Fooder variants masquerade as the Snake game and use delayed execution to evade detection.

🐛 The Glassworm campaign has resurfaced in a third wave, with 24 new malicious VS Code-compatible extensions appearing on both the Microsoft Visual Studio Marketplace and OpenVSX. Once installed, these extensions push updates that deploy Rust-based implants, use invisible Unicode to evade review, exfiltrate GitHub, npm, and OpenVSX credentials and cryptocurrency wallet data, and deploy a SOCKS proxy and an HVNC client for stealthy remote access. Researchers say attackers inflate download counts to blend with legitimate projects and manipulate search results; both vendors have been contacted about continued bypasses.

🛡️ A new Android malware family, Albiriox, has emerged on Russian-speaking cybercrime forums as a Malware-as-a-Service offering full device takeover and real-time fraud capabilities. Cleafy says it already targets more than 400 banking and cryptocurrency applications and combines VNC-style remote control with accessibility-driven UI automation, overlays and black-screen fraud techniques. Initial subscriptions were advertised at $650–$720 per month and the developers promote crypting to evade detection.

🛡️ Socket researchers detail a sophisticated NPM supply-chain campaign that uses fake coding interviews to trick developers into installing trojanized packages. Attackers operate a
