DoubleZero: A data wiper deployed against Ukraine
The DoubleZero wiper — so named for its tactic of zeroing files — was first discovered on March 17, 2022 by CERT-UA (the Computer Emergency Response Team of Ukraine). The malware was designed in order to wipe out system files, non-system files and entire registry branches, and was spread by spear phishing emails with an attached ZIP that contains the malware file.
