Ukraine Computer Emergency Response Team (CERT-UA) reported a phishing campaign using messages with subject “On revenge in Kherson!” and containing the “Plan Kherson.htm” attachment. The HTM-file will decode and create an archive named “Herson.rar”, which contains a file-shortcut named “Plan of approach and planting explosives on the objects of critical infrastructure of Kherson.lnk”. Ukraine CERT-UA Upon clicking on the link file, the HTA-file “precarious.xml” is loaded and executed leading to the creation and execution of files “desktop.txt” and “user.txt”. In the last stage of the attack chain, the GammaLoad.PS1_v2 malware is downloaded and executed on the victim’s computer. The government experts attributes the attack to the Russia-linked Armageddon APT (UAC-0010) (aka Gamaredon, Primitive Bear, Armageddon, Winterflounder, or Iron Tilden) which was involved in a long string of attacks against the local state organizations.  “As a result, the malicious program GammaLoad.PS1_v2 will be downloaded to the computer (the mechanism of taking a screenshot and sending it to the management server has been implemented).” reads the advisory published by CERT-UA. “The activity is carried out by the group UAC-0010 (Armageddon).” The Ukrainian CERT shared the indicators of compromise (IoCs) for this campaign.
