TVRAT exploits a vulnerability in TeamViewer
Assessment
The indictment (¶8) and the release both say TVRAT "exploits a vulnerability" in TeamViewer. Public technical analysis does not describe one. Avast's April 2017 examination of a macro-delivered TeamSpy sample found legitimate, digitally signed TeamViewer binaries installed together with a malicious msimg32.dll, loaded through DLL search-order hijacking because Windows looks in the application directory first. TeamViewer functions as designed and the operator connects through its normal infrastructure. That is abuse of a trusted tool, not exploitation of a flaw in it. The indictment's phrasing is a lay description; no CVE has ever been assigned to TeamSpy's mechanism.

Evidence exists but is thin, circumstantial, or explicitly qualified as weak by the source that published it. Shared hosting infrastructure between threat clusters is the recurring example.
