Sting

Sting is a data-wiping malware family used by the Russia-linked Sandworm threat group in 2025. Reporting in the provided content consistently describes Sting as a wiper deployed in destructive operations against Ukrainian targets. ESET and other cited reporting state that Sting was first observed alongside ZEROLOT against a Ukrainian university in April 2025, including execution via a Windows scheduled task named DavaniGulyashaSdeshka. Subsequent Sandworm activity between June and September 2025 used Sting and ZEROLOT against Ukrainian governmental entities and organizations in the energy, logistics, and grain sectors, with the grain-sector targeting described as likely intended to weaken the Ukrainian economy. The content places Sting within Sandworm’s broader destructive malware arsenal alongside families such as PathWiper and HermeticWiper. High-confidence behavior directly stated in the content is that Sting is wiper malware designed to permanently erase data and disrupt operations. The malware is associated with Sandworm, a GRU-linked Russian state threat actor, and with attacks focused on Ukraine’s critical and economically important sectors. No standalone technical indicators such as hashes or domains are provided for Sting in the supplied content.
