VERY IMPORTANT

In May and June 2026, the Clubfoot Wolf cluster executed a large-scale phishing campaign targeting Russian organizations across manufacturing, retail, e-commerce, agriculture, IT, transportation, healthcare, and science sectors, with primary focus on wholesale distributors of chemical products. Several Belarusian organizations were also compromised. The adversary sent phishing emails disguised as invoices or purchase requests, containing ZIP archives with decoy documents and malicious LNK files. Upon execution, a PowerShell script downloaded and installed NetSupport Manager, a legitimate remote administration tool, which was then used for malicious activities. The attackers employed URL shorteners to hide infrastructure and used multiple decoy files to build victim trust. The campaign demonstrated continuous evolution in delivery methods and infection chains.
