A Russian-linked APT group, known as UAC-0063, is actively targeting Kazakhstan and other Central Asian countries in a cyber espionage campaign. This group, which has connections to APT28 and Russian GRU cyber activities, is using spear-phishing tactics. They utilize weaponized Microsoft Office documents, designed to deploy the HATVIBE malware and CHERRYSPY. The campaign's goal is to gather economic and political intelligence. The Computer Emergency Response Team of Ukraine (CERT-UA) first detailed UAC-0063's activities in early 2023, noting that their targets include government entities across Ukraine, Central Asia, East Asia, and Europe.

The attack chain, dubbed "Double-Tap" by researchers, begins when a user enables a malicious macro in a spear-phishing document. This macro creates a second weaponized document and opens it in a hidden instance of Microsoft Word. This then executes a malicious HTA file embedding a VBS backdoor named HATVIBE. HATVIBE acts as a loader, downloading further VBS modules leading to the deployment of a Python backdoor known as CHERRYSPY. These techniques allow the malware to bypass security measures and maintain persistence.
