Published: 2018-06-05 05:40:29

CVSS Base Vector:
AV:N/AC:L/Au:N/C:C/I:C/A:C

Summary:
The host is running an unprotected Redis server which is compromised via the 'RedisWannaMine' attack.

Detection Method:
The script is sending commands to the remote Redis server and checks for the following indicators of compromise (IOC): - datadir set to c:\temp, c:\tmp, /var/spool/cron, /etc/crontabs, /etc, /proc or /tmp - the existence of at least one of the following keys: trojan1, trojan2, backup1, backup2, backup3, crackit

Impact:
The 'RedisWannaMine' drops an crypto miner on the target to misuse the host resources for crypto mining. Furthermore it will try to attack other hosts via the SMB attack 'WannaCry'.

Affected Versions:
All Redis server publicly accessible without authentication.

Recommendations:
A whole cleanup of the infected system is recommended. Additionally block all traffic to the redis server or enable authentication.

Solution Type:
Workaround

Detection Type:
Remote Vulnerability

Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
