Procedure timeline
Search the case steps or filter them by attacker goal.
-
Initial Access
Step 1
Valid Accounts
APT28 gained access to a compromised official email account.
-
Lateral Movement
Step 2
Phishing
APT28 sent a phishing email from the compromised account with an attachment containing malware.
-
Defense Evasion
Step 3
Impersonation
The email impersonated a government ministry representative.
-
Defense Evasion
Step 4
Masquerading
The attachment was called “Appendix.pdf.zip” which could confuse the recipient into thinking it was a legitimate PDF file.
-
Execution
Step 5
User Execution
The attachment contained an executable file with a .pif extension, created using PyInstaller from Python source code which CERT-UA classified it as LAMEHUG malware. Files with the .pif extension are executable on Windows.
-
AI Attack Staging The LAMEHUG malware abused the Qwen 2.5 Coder 32B Instruct model Hugging Face API to generate malicious commands from natural language prompts.
-
Collection
Step 7
Data from Local System
The LAMEHUG malware used the AI generated commands to collect system information (saved to
%PROGRAMDATA%\info\info.txt) and recursively searched Documents, Desktop, and Downloads to stage files for exfiltration. -
Exfiltration The LAMEHUG malware exfiltrated collected data to attacker controlled servers via SFTP or HTTP POST requests.
