Turla’s New ‘DeliveryCheck’ Backdoor Compromises Ukrainian Defense Sector
On July 20, 2023, reports emerged of a sophisticated .NET-based backdoor known as DeliveryCheck (also referred to as CAPIBAR or GAMEDAY) targeting the defense sector in Ukraine and Eastern Europe. Attributed to the Russian nation-state actor Turla—also recognized by aliases such as Iron Hunter, Secret Blizzard (formerly Krypton), Uroburos, Venomous Bear, and Waterbug—this malware is associated with Russia’s Federal Security Service (FSB). According to the Microsoft threat intelligence team, in partnership with the Computer Emergency Response Team of Ukraine (CERT-UA), DeliveryCheck is distributed through malicious email attachments containing harmful macros. The backdoor maintains persistence via a scheduled task that downloads and executes it in memory.

Wiz Reports: Microsoft Attack Using Azure AD Token Forging Technique Has Wider Implications Beyond Outlook
On July 21, 2023, it was revealed that the recent breach of Microsoft’s email services by the Chinese state-sponsored group Storm-0558 is more extensive than initially suspected. According to cloud security firm Wiz, the attack exploited an inactive consumer signing key from Microsoft accounts (MSA) to forge Azure Active Directory (Azure AD) tokens, allowing unauthorized access not just to Outlook Web Access (OWA) and Outlook.com, but potentially to a wide range of Azure AD applications.
