Ongoing Social Engineering Campaign Refreshes Payloads
On June 20, 2024, Rapid7 identified multiple intrusion attempts by threat actors utilizing Techniques, Tactics, and Procedures (TTPs) that are consistent with an ongoing social engineering campaign being tracked by Rapid7.
Black Basta ransomware switches to more evasive custom malware
The Black Basta ransomware gang has shown resilience and an ability to adapt to a constantly shifting space, using new custom tools and tactics to evade detection and spread throughout a network.
In mid-2022, Mandiant's Managed Defense detected multiple intrusions involving QAKBOT, leading to the deployment of BEACON coupled with other pre-ransomware indicators. This marked Mandiant's initial identification of UNC4393, the primary user of BASTA ransomware. Mandiant has responded to over 40 separate UNC4393 intrusions across 20 different industry verticals. While healthcare organizations have not traditionally been a focus for UNC4393, several breaches in the industry this year indicate a possible expansion of their interests. However, this represents only a fraction of the cluster's victims, with the Black Basta data leak site purporting over 500 victims since inception. Over the course of this blog post, Mandiant will detail the evolution of UNC4393's operational tactics and malware usage throughout its active lifespan, with a focus on the period following the QAKBOT botnet takedown. We will highlight the cluster's transition from readily available tools to custom malware development as well as its evolving reliance on access brokers and diversification of initial access techniques.
Threat actors misusing Quick Assist in social engineering attacks leading to ransomware
Microsoft Threat Intelligence has observed Storm-1811 misusing the client management tool Quick Assist to target users in social engineering attacks that lead to malware like Qakbot followed by Black Basta ransomware deployment.
le team sa - Informations sur le cyberincident chez leteam sa
En décembre 2023, leteam sa a été victime d'une cyber-attaque. Un groupe de ransomware connu a pu accéder au réseau et crypter plusieurs disques. Grâce à une réaction rapide de l'équipe informatique et d'experts en sécurité externes, l'attaque a pu être rapidement contrée et les systèmes restaurés. L'analyse de l'incident a révélé une fuite de certaines données, mais celle-ci a été jugée à l'époque comme étant partiellement critique. Un monitoring a été mis en place pour surveiller une éventuelle publication de données.
