A botnet is using Exchange server vulnerabilities to mine cryptocurrency on infected PCs
The Microsoft Exchange server drama continues. While patches are bachelor and efforts have been taken to mitigate and fix vulnerabilities in Microsoft Exchange servers, a new botnet is on the hunt for unpatched servers. Prometei is a cryptocurrency botnet that'due south being used to target organizations around the earth. The botnet scans the web for organizations that haven't applied patches to fix vulnerabilities to work itself into networks.
Cybersecurity researchers at Cybereason detail the malware attack (via ZDNet). 1 of the key findings of Cybereason is that Prometei exploits the vulnerabilities associated with the HAFNIUM attacks. The botnet uses these vulnerabilities to work itself into networks, which allows it to harvest information and mine for the Monero cryptocurrency.
Once Prometei works itself way into a network, it tin use several techniques to motion around, including harvesting login credentials, exploiting RDP vulnerabilities, and using older exploits. These techniques tin can be used to infect several machines.
The vast majority of organizations take installed patches or mitigated vulnerabilities in Substitution servers associated with the HAFNIUM attacks, merely Prometei can observe unpatched and vulnerable servers.
Prometei has been utilized to attack victims in several industries in North America, South America, Europe, and East Asia.
Microsoft and other organizations have taken several steps to fix the vulnerabilities used in the attacks on Exchange servers. Equally previously reported, hackers are racing to take advantage of unpatched servers. It seems that this will go on to be an issue until all servers are patched or fixed.
