BlueDelta Exploits Ukrainian Government Roundcube Mail Servers to Support Espionage Activities | Recorded Future
Recorded Future's Insikt Group, in partnership with Ukraine's Computer Emergency Response Team (CERT-UA), has uncovered a campaign targeting high-profile entities in Ukraine that was cross-correlated with a spearphishing campaign uncovered by Recorded Future’s Network Traffic Intelligence.
