The Lumma Stealer malware campaign is exploiting compromised educational institutions to distribute malicious LNK files disguised as PDFs, targeting industries like finance, healthcare, technology, and media. Once executed, these files initiate a stealthy multi-stage infection process, allowing cybercriminals to steal passwords, browser data, and cryptocurrency wallets. With sophisticated evasion techniques, including using Steam profiles for command-and-control operations, this malware-as-a-service (MaaS) threat highlights the urgent need for robust cybersecurity defenses. Stay vigilant against deceptive phishing tactics to protect sensitive information from cyber exploitation.

North Korea is behind the massive crypto hack, according to several blockchain monitoring firms and a well-known researcher

• Proofpoint identified and named two new cybercriminal threat actors operating components of web inject campaigns, TA2726 and TA2727.
• Proofpoint identified a new MacOS malware delivered via web inject campaigns that our researchers called FrigidStealer.
• The web inject campaign landscape is increasing, with a variety of copycat threat actors conducting similar campaigns, which can make it difficult for analysts to track.

On February 21, 2025, at approximately 12:30 PM UTC , Bybit detected unauthorized activity within one of our Ethereum (ETH) Cold Wallets during a routine transfer process. The transfer was part of a scheduled move of ETH from our ETH Multisig Cold Wallet to our Hot Wallet. Unfortunately, the transaction was manipulated by a sophisticated attack that altered the smart contract logic and masked the signing interface, enabling the attacker to gain control of the ETH Cold Wallet. As a result, over 400,000 ETH and stETH worth more than $1.5 billion were transferred to an unidentified address.

Cisco Talos has been closely monitoring reports of widespread intrusion activity against several major U.S. telecommunications companies, by a threat actor dubbed Salt Typhoon. This blog highlights our observations on this campaign and identifies recommendations for detection and prevention.

Le Cloud computing, devenu incontournable pour les secteurs public et privé, favorise la transformation numérique mais offre également de nouvelles opportunités d’attaques et problématiques de sécurité pour les organisations qui l’utilisent.

L'ANSSI observe une augmentation des attaques contre les environnements cloud. Ces campagnes d'attaques, menées à des fins lucratives, d'espionnage et de déstabilisation, affectent les fournisseurs de services cloud (Cloud Service Provider, CSP), en partie ciblés pour les accès qu’ils peuvent offrir vers leurs clients. Elles ciblent également les environnements de clients de services cloud, dont l'hybridation des systèmes d'information générée par l'usage du cloud, augmente la surface d'attaque.

• An unknown threat cluster has been targeting at least between June and October 2024 European organizations, notably in the healthcare sector.
• Tracked as Green Nailao by Orange Cyberdefense CERT, the campaign relied on DLL search-order hijacking to deploy ShadowPad and PlugX – two implants often associated with China-nexus targeted intrusions.
• The ShadowPad variant our reverse-engineering team analyzed is highly obfuscated and uses Windows services and registry keys to persist on the system in the event of a reboot.
• In several Incident Response engagements, we observed the consecutive deployment of a previously undocumented ransomware payload.
• The campaign was enabled by the exploitation of CVE-2024-24919 (link for our World Watch and Vulnerability Intelligence customers) on vulnerable Check Point Security Gateways.

Researchers can disclose two brand-new vulnerabilities in OpenSSH now that patches have been released.

Qualys discovered the bugs in January, per its disclosure timeline. These vulnerabilities allow miscreants to perform machine-in-the-middle (MitM) attacks on the OpenSSH client and pre-authentication denial-of-service (DoS) attacks.

Patches for CVE-2025-26465 and CVE-2025-26466 were released this morning. Although their respective severity scores (6.8 and 5.9 out of 10) don't necessarily scream "patch me right away" – it certainly doesn't seem as bad as last year's regreSSHion issue – they're both likely to raise some degree of concern given the tool's prominence.

First observed in March 2024, “BlackLock” (aka El Dorado or Eldorado) has rapidly emerged as a major player in the ransomware-as-a-service (RaaS) ecosystem. By Q4 2024, it ranked as the 7th most prolific ransomware group on data-leak sites, fueled by a staggering 1,425% increase in activity from Q3. BlackLock uses a double extortion tactic—encrypting data while stealing sensitive information—to pressure victims with the threat of public exposure. Its ransomware is built to target Windows, VMWare ESXi, and Linux environments, though the Linux variant offers fewer features than its Windows counterpart.

The National Assembly, Ecuador's unicameral legislature, says it was able to "identify and counteract" attempts by malicious hackers to breach sensitive systems.
