An ongoing social engineering campaign linked to the Black Basta ransomware group involves multiple intrusion attempts aiming at credential theft and deploying the SystemBC malware dropper. Threat actors use tactics such as email bombing, phone calls, and fake solutions to persuade users to download legitimate remote access software for deploying malware. Multiple loader strains have emerged in 2024, including GootLoader, advertised on dark web cybercriminal forums. Phishing and social engineering attacks continue to evolve, utilizing techniques such as fake websites and malvertising campaigns to distribute malware and steal sensitive data. Robust security measures are crucial to protect against these threats.
From the meeting notes on Aug 14, 2024, the key takeaways are:
1. An ongoing social engineering campaign linked to the Black Basta ransomware group has been identified, aiming at conducting credential theft and deploying malicious software.
2. The attack chain involves the use of emails, phone calls via Microsoft Teams, and a legitimate remote access software named AnyDesk to deliver follow-on payloads and exfiltrate sensitive data.
3. Threat mitigation measures include blocking unapproved remote desktop solutions, being vigilant of suspicious phone calls, and texts claiming to be from internal IT staff.
4. SocGholish, GootLoader, and Raspberry Robin are the most commonly observed loader strains in 2024, with GootLoader replacing QakBot on the top-three list this year.
5. Malware loaders are advertised on dark web cybercriminal forums, often through subscription models, allowing even threat actors with limited technical expertise to mount sophisticated attacks.
6. Phishing attacks have been observed distributing the 0bj3ctivity Stealer through an Ande Loader as part of a multi-layered distribution mechanism.
7. Various campaigns utilizing fake websites and social media malvertising have been identified, highlighting the importance of robust security measures to protect account credentials and prevent unauthorized access.
These takeaways emphasize the prevalence of social engineering and phishing attacks, the evolving tactics of threat actors, and the need for advanced detection mechanisms and continuous research to combat these cyber threats.
