If you already ran it
Disconnect from the internet, start a full or offline antivirus scan, then secure important accounts from a clean device.
Intelligence
The saved assessment, checked against the scan evidence and recorded coverage.
The reasoning behind this verdict
This section explains the evidence supporting the verdict and keeps conflicting or missing signals visible.
40 of 74 engines flag the sample, including 8 tier-1 engines that converge on the defendercontrol family. The file carries six offensive MITRE techniques and is listed as known malicious by CIRCL.
The tier-1 family consensus on defendercontrol is strong and corroborated by multiple high-trust engines. Offensive techniques such as process injection and defense evasion align with hacktool behaviour. The signer has no historical samples in our records, removing any benign-publisher benefit. Community annotations and the CIRCL known-malicious flag reinforce the engine findings.
What We Detected
8 tier-1 engines and 32 additional engines classify the file as a hacktool targeting Windows Defender. The filename explicitly references disabling Defender, and the binary exhibits six offensive MITRE techniques including T1055 (process injection) and T1562.001 (impair defenses).
Threat Behavior
Runtime evidence shows direct-IP connections, persistence indicators, and registry modifications consistent with tools designed to neutralize security software. The sample is signed by an untracked publisher and appears on malware repositories.
What To Do Now
Do not execute the file. Keep endpoint protection enabled and remove the sample from any system where it was downloaded.
- Strong tier-1 hacktool consensus
- Offensive MITRE techniques observed
- Filename mimics security software
- CIRCL marks as known malicious
- Unsigned or unverified signer with no history
Treat the file as malicious and block or delete it; maintain all security software in an active state.

What this file does
Observed actions and their security significance
High concern: Injected code into another process, a technique that can conceal execution.
High concern: Used an input-capture technique that can record credentials or keystrokes.
High concern: Created or modified a system service, which can keep code running.
High concern: Changed an auto-start location that can make code run after sign-in or restart.
High concern: Attempted to impair or bypass security controls.
High concern: Manipulated how the operating system loads code, which can redirect execution.
Moderate concern: Contained obfuscated or packed code that makes inspection harder.
These are observed capabilities from an isolated analysis. A technique does not prove malicious intent on its own, and the file never ran on your device.
Threat context
How hacktools are abused
This is a hacking or cracking tool — the kind used to bypass software licences, generate fake keys, or attack other systems. Even when the tool 'works', these downloads very often carry hidden malware.
Bottom line:Running one means trusting an anonymous author with full access to your PC — rarely worth the risk.

Signatures and behavior heuristics
A community signature or high-severity behavioral heuristic matched. Signatures identify known patterns; heuristics are strong leads but are not proof on their own.
Sandbox flagged persistence indicators (registry Run keys / services / scheduled tasks).
EvidencecsccThe saved runtime evidence maps this activity to MITRE T1055 (Process Injection). The mapping supports possible process injection, but it does not prove the exact injection method or the operator's intent.
Evidence"C:\Users\<USER>\Desktop\program.exe"The sample contacted an external IP address directly and no application domain was recorded. Direct-IP traffic also occurs in legitimate installers and infrastructure, so this is supporting context only and requires corroboration from host reputation and other runtime evidence.

Section entropy & packers
No high-entropy executable section or known packer signature was detected. Data and resource sections can still have high entropy without indicating packed code.
How widely this file has been seen
Widely seen in the wild for a long time. High prior this is legitimate; isolated detections on common-old files are usually false positives.
