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.

Luis S. est un Genevois qui recueille des données d'intérêt public sur le darknet pour les fournir aux médias romands. Dans le cadre de cette activité, il a été perquisitionné en 2023 par la police fédérale, puis blanchi. Mais entretemps, des documents ont disparu dans les supports informatiques saisis, notamment des échanges avec des journalistes.

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.

A new variant of the XCSSET macOS modular malware has emerged in attacks that target users' sensitive information, including digital wallets and data from the legitimate Notes app.

A critical PHP vulnerability (CVE-2022-31631) could expose websites and applications to SQL injection attacks, leading to data breaches and system compromise.

Our first network security analysis of the popular Chinese social media platform, RedNote, revealed numerous issues with the Android and iOS versions of the app. Most notably, we found that both the Android and iOS versions of RedNote fetch viewed images and videos without any encryption, which enables network eavesdroppers to learn exactly what content users are browsing. We also found a vulnerability in the Android version that enables network attackers to learn the contents of files on users’ devices. We disclosed the vulnerability issues to RedNote, and its vendors NEXTDATA, and MobTech, but did not receive a response from any party. This report underscores the importance of using well-supported encryption implementations, such as transport layer security (TLS). We recommend that users who are highly concerned about network surveillance from any party refrain from using RedNote until these security issues are resolved.

One of the challenges with investigating cybercrime is the infrastructure the adversaries leverage to conduct attacks. Cybercriminal infrastructure has evolved drastically over the last 25 years, which now involves hijacking web services, content distribution networks (CDNs), residential proxies, fast flux DNS, domain generation algorithms (DGAs), botnets of IoT devices, the Tor network, and all sorts of nested services.

This blog shall investigate a small UK-based hosting provider known as BitLaunch as an example of how challenging it can be to tackle cybercriminal infrastructure. Research into this hosting provider revealed that they appear to have a multi-year history of cybercriminals using BitLaunch to host command-and-control (C2) servers via their Anonymous VPS service.
