Information on the Netlab 360 blog
What is the danger of a critical vulnerability? Log4Shell or LogJam is a Remote Code Execution class vulnerability. If the attackers manage to exploit it on one of the servers, they will be able to execute the arbitrary code and take full control of the system. The hackers took advantage of the situation to launch the Kinsing crypto miners and organize large-scale DDoS attacks. .
What are the experts saying? The Apache Foundation recommends that all developers upgrade the library to version 2.15.0, or if this is not possible, use one of the methods described on the Apache Log4j Security Vulnerabilities page. The experts added:
“At the moment, there have been no instances of exploitation of vulnerabilities by ransomware or APT-groups, however, the fact of the deployment of Cobalt Strike beacons indicates the forthcoming malicious campaigns.”
