It’s a worrying trend that ransomware isn’t going away. Worse, it's constantly adapting to include brand new exploits/techniques and spreads in more innovative and successful ways.
Today, we are sharing an example of how previously known malware keeps evolving and adding new techniques to infect more systems.
BleepingComputer first reported on Satan ransomware in January 2017. Recently, Satan Ransomware was identified as using the EternalBlue exploit to spread across compromised environments.
This is the same exploit associated with a previous WannaCry Ransomware campaign. While Microsoft patched the vulnerability associated with EternalBlue in March 2017, many environments remain vulnerable.
IT security provider Alienvault identified samples of Satan Ransomware that not only include EternalBlue, but also a far larger set of propagation methods, variant attempts to propagate through:
- JBoss CVE-2017-12149
- Weblogic CVE-2017-10271
- EternalBlue exploit CVE-2017-0143
- Tomcat web application brute forcing
