Loading malware…
LoadLoop is a malware loader associated with Sandworm activity, including campaigns attributed to the CERT-UA cluster UAC-0145 targeting Ukraine in 2026. It has been observed as part of a broader intrusion set delivered through ClickFix-style social engineering in which compromised websites display fake CAPTCHA or verification prompts that trick victims into executing malicious PowerShell commands on Windows systems. In these operations, LoadLoop appeared alongside other Sandworm tooling such as GHETTOVIBE, SCOUTCURL, FLUIDLEECH, and the Python backdoor FREAKYPOLL.
Within the observed infection chains, LoadLoop functioned as a follow-on payload used after initial compromise and reconnaissance, particularly on systems assessed as valuable. Its role as a loader indicates use for staging or executing additional malicious components to extend attacker access and support persistent operations. The surrounding campaigns combined user-executed PowerShell, reconnaissance, persistence mechanisms, and subsequent deployment of additional malware, consistent with targeted post-compromise tradecraft.
LoadLoop has been reported in operations focused on Ukrainian targets and linked to Russian state-sponsored intrusion activity associated with Sandworm, also tracked as UAC-0002, APT44, and Seashell Blizzard. High-confidence reporting supports Windows as the relevant platform in the documented ClickFix delivery chains.

3 distinct threat actors attributed by public researchers. Open in Mallory to see the full evidence chain and overlapping campaigns.
If the target was valuable, the threat actors used other malware samples to gain persistent access to the system. For example, FluidLeech, a fake antivirus software, and LoadLoop, a loader, were also used in the attacks.
