Ex-Black Basta Members Leverage Microsoft Teams and Python Scripts in Latest Cyber Attacks
TL;DR
Former Black Basta ransomware members continue to use email phishing and Microsoft Teams for persistent network access. New tactics include Python script execution and cURL requests to deploy malicious payloads.
Introduction
Former members associated with the notorious Black Basta ransomware operation have been observed employing familiar tactics such as email phishing and Microsoft Teams exploitation to gain persistent access to target networks. In a recent development, these attackers have introduced Python script execution, combined with cURL requests, to fetch and deploy malicious payloads. This evolving strategy underscores the need for enhanced cybersecurity measures to counter these threats.
Persistent Tactics and New Techniques
Email Phishing and Microsoft Teams Exploitation
The former Black Basta members have consistently relied on email phishing and Microsoft Teams as vectors for their attacks. These methods allow them to establish a foothold within target networks, providing long-term access for further malicious activities.
Introduction of Python Scripts and cURL Requests
In a recent report, ReliaQuest highlighted the attackers’ adoption of Python script execution alongside their traditional tactics. These scripts, when combined with cURL requests, enable the retrieval and deployment of malicious payloads, adding a new layer of complexity to their operations.
Implications for Cybersecurity
The evolution of these tactics emphasizes the importance of robust cybersecurity measures. Organizations must stay vigilant and implement comprehensive security protocols to protect against these advanced threats. Regular updates and employee training on recognizing phishing attempts are crucial in mitigating risks.
Conclusion
The continuous adaptation of tactics by former Black Basta members highlights the dynamic nature of cyber threats. As attackers integrate new methods like Python script execution and cURL requests, the cybersecurity community must respond with innovative solutions to safeguard sensitive information and maintain network integrity.
