The SVR continues attacking computer companies with this newly attributed operation that targets networks that host TeamCity servers.  The authoring agencies determine that by taking advantage of CVE2023-42793, a software development program, the SVR might gain access to victims, especially by giving the threat actors the ability to compromise the networks of several software developers. The flaw identified as CVE2023-42793 impacts the version before 2023.05.4; it was possible to bypass authentication in JetBrains TeamCity, which might result in RCE on TeamCity Server.
