In a report published in September 2023, Microsoft linked the group to password spray attacks carried out against thousands of organizations globally between February and July 2023. The intrusions primarily singled out satellite, defense, and pharmaceutical sectors.

The agency also revealed details of a phishing campaign in which a fake advisory for a security flaw in F5 BIG-IP products is employed as a decoy to deliver wiper malware on Windows and Linux systems.
The lure for the targeted attack is a critical authentication bypass vulnerability (CVE-2023-46747, CVSS score: 9.8) that came to light in late October 2023. The scale of the campaign is currently unknown.
