The russia-linked Armageddon APT aka Gamaredon or UAC-0010 has been launching a series of cyber attacks on Ukraine since the outbreak of the global cyber war. On November 8, 2022, CERT-UA released the latest alert detailing the ongoing spearphishing campaign of this russia-backed cyber-espionage hacking collective, in which adversaries massively distribute spoofed emails masquerading as State Special Communications Service of Ukraine. In this targeted adversary campaign, Armageddon APT hackers exploit the malicious email attachment attack vector.
Armageddon APT (UAC-0010) Cyber Attacks: Analysis of the Latest Phishing Campaign Against Ukraine
Since russia’s full-scale invasion of Ukraine, the notorious russia-linked Armageddon APT group also tracked as UAC-0010 or Primitive Bear has been actively exploiting phishing and malicious email attachment attack vectors in targeted campaigns against Ukraine. In May and July 2022, the hacking collective has been massively distributing the GammaLoad.PS1_v2 malicious software, while in August 2022, adversaries applied GammaSteel.PS1 and GammaSteel.NET malware for spreading infection on the compromised systems.
CERT-UA researchers report that phishing emails are being delivered via the @mail.gov.ua service. In addition, Armageddon APT hackers apply their common adversary patterns to launch cyber attacks using a third-party service or Telegram to identify the IP address of the C2 server.
