🚨 New Qilin Ransomware Campaign Targets MSPs Through Sophisticated Phishing Attacks
The managed service provider (MSP) landscape is facing a new sophisticated threat as Qilin ransomware affiliates deploy advanced phishing techniques to compromise MSP administrators and their downstream customers. This emerging attack pattern, identified as STAC4365 by Sophos, demonstrates how cybercriminals are evolving their tactics to bypass traditional security measures.
The Evolution of MSP-Focused Attacks
The attack methodology is particularly concerning because it targets the trusted relationship between MSPs and their clients. By compromising ScreenConnect credentials through carefully crafted phishing emails that mimic legitimate login alerts, attackers can gain access to multiple organizations simultaneously. What makes this campaign especially dangerous is its ability to intercept both credentials and MFA tokens using the evilginx adversary-in-the-middle framework.
Breaking Down the Attack Chain
Once inside, the attackers' playbook includes several sophisticated steps:
- Deployment of malicious ScreenConnect instances across customer environments
- Systematic disabling of backup systems before ransomware deployment
- Implementation of double-extortion tactics, including data exfiltration
- Unique encryption passwords and chat IDs for each victim
