About this tag
The turla tag on WindowsForum.com collects coverage of the Russia-aligned espionage group Turla and its tooling against Microsoft infrastructure. The tagged discussion centers on ESET research into the Cereal toolset, which turned compromised Microsoft Exchange servers into both email-surveillance systems and command channels at government organizations in Kazakhstan and Romania, including a deployment configured to target correspondence involving NATO and European Union institutional addresses. For Windows and Exchange administrators, the recurring theme is that collection occurred inside legitimate mail-processing activity while messages continued toward their destinations, making the intrusion harder to spot through ordinary mail flow alone.
