TA445 is a state-sponsored threat-activity cluster tracked by Proofpoint that includes UNC1151 and is associated with Ghostwriter activity. Its UNC1151 component has conducted widespread phishing campaigns targeting the private email accounts of Ukrainian armed service members. TA445 has also abused webmail vulnerabilities to compromise mail servers and steal email contents. These activities center on gaining access to email accounts and collecting mailbox data. UNC1151 is tracked as part of TA445, rather than necessarily representing the entirety of the cluster.

Mentioned as background among previously documented actors exploiting webmail XSS vulnerabilities for cyber espionage. The passage collectively discusses Russian and Belarusian actors but does not individually establish TA445's origin or sponsor.
Belarus-linked activity cluster associated with hybrid operations (disinformation + cyber). In this reporting, TA445 is discussed as a likely-aligned actor for phishing/credential-harvesting and intelligence collection focused on refugee movement/logistics and NATO/European government targets; however, Proofpoint does not definitively attribute the SunSeed “Asylum Ambuscade” intrusion chain to TA445.
