Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

We are investigating high outbound traffic on Tomcat servers hosted on AWS instances.

The specific question I have is what the process nodeJR is - and how it could get installed under Tomcat?

The situation:

  • There were open TCP connections from my IP to 162.221.12.185
  • 165.221.12.185 is resolving as “clear-ddos.com” which is a DDOS scrubbing service
  • The Admin team blocked all inbound / outbound traffic to 165.221.12.185
  • The network traffic stabilized after blocking the traffic
  • Via a netstat we saw the Tomcat server was still attempting to establish the TCP connection, however it was failing since the traffic was blocked. We saw multiple SYN requests and re-tries
  • We tied this connection to the process “nodeJR”, it appears this was installed under root 7 days back

tcp 0 1 172.x.x.x:35073 162.221.12.185:10991 SYN_SENT 7950/./nodeJR

  • We killed the process and restarted the server. The process did not restart.

As per @metacom's comment, I ran strings on the /nodeJR process. ldd says not a dynamic executable

In between the wall of 4-character text - I can see

could you upload the binary somewhere? if not the output of strings and ldd may give an idea –  metacom Apr 15 at 13:40
    
@metacom: added strings output - not sure what i should be looking for though –  JoseK Apr 15 at 14:12
    
An unknown process opening (many) connections to the outside is malicious, typically trying to brute-force passwords or generate DoS. Some texts in its contents are not reassuring: "attack thread" "money" "baidu.com" (large Chinese site). You can try and contact the end point web site to verify, probably just a victim. The malicious code probably came due to a web vulnerability and a random scan. In any case you can treat this as serverfault.com/questions/218005/… –  LinuxDevOps Apr 15 at 14:33
    
All evidence confirms one fact: the server has been compromised. Upon isolation of the server your team's gonna be busy conducting a thorough security audit... Not sure how the community might help you though. –  yarek Apr 20 at 13:38
