ANALYSIS OF THE THREAT CASE OF KIMSUKY GROUP USING 'CLICKFIX' TACTIC
Summary from the TLDR InfoSec newsletter
The Kimsuky APT group has evolved its "ClickFix" tactic, tricking users into executing malicious PowerShell commands disguised as troubleshooting guides or security checks. The campaign uses spear-phishing emails, fake job sites, and compromised sites, employing obfuscation and multilingual variants to evade detection. Defense involves EDR monitoring for abnormal PowerShell activity and user education to identify prompts that ask users to copy and paste codes or "fix" browser issues.
