Microsoft suspects hacker attacks on SolarWinds in another country

According to Microsoft, a country other than Russia is behind the hacker attacks.

The American technology company Microsoft, more precisely its division Microsoft Threat Intelligence Center (MSTIC), suspects Chinese hackers from a hacking attack on SolarWinds. More precisely, it is a hacker group called – DEV-0322, which was supposed to misuse the so-called “zero-day exploit”. According to the company, the group was to focus on FTP software from SolarWinds – Serv-U, which was to misuse it to access US companies operating in the defense industry. The attack itself was noticed by the Microsoft 365 Defender antivirus program during a normal scan.

In addition to anomalous malicious activity, the antivirus software also detected an attacker’s attempt to take over administrator rights over the Serv-U software. On June 9, SolarWinds reported exploiting a bug in the program, stating that the bug affected all versions released before May 5. The affected company, meanwhile, has released a patch for the infected versions of the Serv-U software. Microsoft also informs about the Secure Shell (SSH) protocol, which is used in the Serv-U program, where there is a risk of misuse if it is connected to the Internet.

The first attack was to be carried out in December 2020, with Chinese hackers from the DEV-0322 group to be responsible for it. The Russian hacking group Cozy Bear is to be responsible for this current one.
