| Texte | ## Instantané
The joint Cybersecurity Advisory (CSA) released by the FBI, CISA, HHS, and MS-ISAC provides detailed information on the Black Basta ransomware variant, a ransomware-as-a-service (RaaS) that has targeted critical infrastructure sectors, including healthcare.
## Description
Les affiliés Black Basta ont un accès initial par le biais de techniques telles que le phishing, l'exploitation des vulnérabilités et abuser des références valides.Une fois à l'intérieur du réseau de la victime, ils utilisent un modèle à double expression, cryptant les systèmes et exfiltrant des données.
Les acteurs de la menace utilisent divers outils pour la numérisation du réseau, la reconnaissance, le mouvement latéral, l'escalade des privilèges, l'exfiltration et le chiffrement, y compris le scanner de réseau SoftPerfect, BitsAdmin, Psexec, Rclone et Mimikatz.
La variante des ransomwares Black Basta, fonctionnant en tant que RAAS, a eu un impact sur 500 organisations dans le monde en mai 2024, en gagnant principalement un accès initial par la spectre, en exploitant des vulnérabilités connues et en abusant des références valides.Les notes de rançon n'incluent généralement pas une première demande de rançon ou des instructions de paiement, mais fournissent plutôt que les victimes un code unique et leur demander de contacter le groupe de ransomware via une URL .onion accessible via le navigateur TOR.
Le conseil exhorte les organisations d'infrastructures critiques, en particulier celles du secteur de la santé et de la santé publique (HPH), à appliquer des atténuations recommandées pour réduire la probabilité de compromis de Black Basta et d'autres attaques de rançongiciels, et les victimes de ransomwares sont encouragées à signaler l'incident à leurBureau de terrain du FBI local ou CISA.

## Snapshot The joint Cybersecurity Advisory (CSA) released by the FBI, CISA, HHS, and MS-ISAC provides detailed information on the Black Basta ransomware variant, a ransomware-as-a-service (RaaS) that has targeted critical infrastructure sectors, including healthcare. ## Description Black Basta affiliates gain initial access through techniques such as phishing, exploiting vulnerabilities, and abusing valid credentials. Once inside the victim\'s network, they employ a double-extortion model, encrypting systems and exfiltrating data. The threat actors use various tools for network scanning, reconnaissance, lateral movement, privilege escalation, exfiltration, and encryption, including SoftPerfect network scanner, BITSAdmin, PsExec, RClone, and Mimikatz. The Black Basta ransomware variant, operating as a RaaS, has impacted over 500 organizations globally as of May 2024, primarily gaining initial access through spearphishing, exploiting known vulnerabilities, and abusing valid credentials. The ransom notes do not generally include an initial ransom demand or payment instructions, but instead provide victims with a unique code and instruct them to contact the ransomware group via a .onion URL reachable through the Tor browser. The advisory urges critical infrastructure organizations, especially those in the Healthcare and Public Health (HPH) Sector, to apply recommended mitigations to reduce the likelihood of compromise from Black Basta and other ransomware attacks, and victims of ransomware are encouraged to report the incident to their local FBI field office or CISA. ## References ["#StopRansomware: Black Basta"](https://www.cisa.gov/news-events/cybersecurity-advisories/aa24-131a) CISA.
