Verdict
Malicious

Unsigned NSIS executable flagged by Kaspersky and Rising as GuLoader/NSIS downloader with token-manipulation behaviour.

Eight engines detected the sample, including one tier-1 engine naming NSIS.Agent and another explicitly calling GuLoader/NSIS. The file is unsigned, brand new, and drops multiple files under AppData while using T1134 token manipulation.

Do not run this file

Block the hash and avoid execution; treat as a GuLoader downloader until further sandbox confirmation.

The reasoning behind this verdict

This section explains the evidence supporting the verdict and keeps conflicting or missing signals visible.

72%Confidence
High
Analyst conclusion

Eight engines detected the sample, including one tier-1 engine naming NSIS.Agent and another explicitly calling GuLoader/NSIS. The file is unsigned, brand new, and drops multiple files under AppData while using T1134 token manipulation.

Where this verdict could be wrong3 caveats
  • Only 1 tier-1 engine flagged; 10 tier-1 engines reported clean and 51 undetected — coverage is moderate but consensus is weak.
  • No sandbox verdicts, no malicious dropped children, no contacted malicious hosts — runtime behaviour lacks direct C2 or payload execution confirmation.
  • No YARAify or CIRCL hits; similarHashes empty — external researcher corroboration is absent.

These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.

Recommended action

Block the hash and avoid execution; treat as a GuLoader downloader until further sandbox confirmation.

Threat context

How downloaders work

This file is a delivery vehicle. On its own it can look small and harmless, but its job is to quietly pull down and install the REAL payload — often a stealer, ransomware, or bot — from a server the attacker controls.

Bottom line:Because the dangerous part arrives later, early scans can look cleaner than the threat really is.

How up to date is this analysis of STRUCKTOR_UK_ST8960047-2026_07_13.com?
Evidence-based answer
This report reflects the scan run on July 13, 2026. Because a file's hash never changes, the identity of STRUCKTOR_UK_ST8960047-2026_07_13.com is fixed — but antivirus coverage improves over time, so a file that looks clean today can pick up detections later (and vice-versa). If you need the latest picture, MalwareTips staff can re-run the analysis from scratch.
