ClickFix attacks are rapidly becoming a favored tactic among advanced persistent threat (APT) groups from North Korea, Iran, and Russia, particularly in recent cyber-espionage operations. This technique involves malicious websites posing as legitimate software or document-sharing platforms. Targets are enticed through phishing emails or malicious advertising and then confronted with fake error messages claiming a failed document download or access issue. 
To resolve the supposed problem, users are instructed to click a “Fix” button that directs them to run a PowerShell or command-line script. Executing this script allows malware to infiltrate their systems. Microsoft’s Threat Intelligence division highlighted earlier this year that the North Korean group ‘Kimsuky’ utilized a similar approach through a fake “device registration” page.
A new report from Proofpoint now confirms that Kimsuky, along with Iran’s MuddyWater, Russia’s APT28, and the UNK_RemoteRogue group, deployed ClickFix techniques between late 2024 and early 2025.
Kimsuky’s campaign, conducted between January and February 2025, specifically targeted think tanks involved in North Korean policy research. The attackers initially contacted victims using spoofed emails designed to appear as if they were sent by Japanese diplomats. After gaining trust, they provided malicious PDF attachments leading to a counterfeit secure drive. Victims were then asked to manually run a PowerShell command, which triggered the download of a second script that established persistence with scheduled tasks and installed QuasarRAT, all while distracting the victim with a harmless-looking PDF.
In mid-November 2024, Iran’s MuddyWater launched its campaign, targeting 39 organizations across the Middle East. Victims received phishing emails disguised as urgent Microsoft security alerts, prompting them to run PowerShell scripts with administrative rights. This led to the deployment of ‘Level,’ a remote monitoring and management (RMM) tool used to conduct espionage activities.
Meanwhile, Russian group UNK_RemoteRogue focused on two organizations tied to a leading arms manufacturer in December 2024. Attackers used compromised Zimbra servers to send fake Microsoft Office messages. Clicking the embedded links directed victims to fraudulent Microsoft Word pages featuring Russian-language instructions and a video tutorial.
Victims executing the provided script unknowingly triggered JavaScript that ran PowerShell commands, connecting their systems to a server managed through the Empire C2 framework.
Proofpoint also found that APT28, an infamous Russian cyber-espionage unit, used ClickFix tactics as early as October 2024. In that instance, phishing emails mimicked Google Spreadsheet notifications, including a fake reCAPTCHA and a prompt to execute PowerShell commands. Running these commands enabled attackers to create an SSH tunnel and activate Metasploit, providing them with covert access to compromised machines.
The growing use of ClickFix attacks by multiple state-sponsored groups underscores the method’s effectiveness, primarily due to the widespread lack of caution when executing unfamiliar commands. To avoid falling victim, users should be extremely wary of running scripts or commands they do not recognize, particularly when asked to use elevated privileges.
