Is DeltaExecutor.zip safe?
Confirmed hacktool labeling, eight tier-1 detections, and observed process-injection and defense-impairment techniques make this archive unsuitable for execution.
The archive was flagged by 28 of 76 engines, including eight tier-1 engines, with multiple corroborating Process Hacker and generic hacktool labels. Runtime evidence also maps activity to process injection and impairment of defenses, so the file should not be opened or executed.

Before opening or extracting

If you already opened or extracted it
Close it. If it opened links, requested credentials, or triggered unexpected behavior, disconnect from the internet and run a full device scan.
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.
The archive was flagged by 28 of 76 engines, including eight tier-1 engines, with multiple corroborating Process Hacker and generic hacktool labels. Runtime evidence also maps activity to process injection and impairment of defenses, so the file should not be opened or executed.
Multiple independent engines identify offensive tooling inside this archive, and engines.hacktoolConfirmed is set because those labels are corroborated. Eight tier-1 detections substantially strengthen the concern, including Kaspersky's credential-theft label and two VMProtect trojan labels. One sandbox observed techniques mapped to T1055 process injection and T1562.001 impairment of defenses, including rundll32 loading a DLL from a temporary directory. The engines do not agree strongly on one conventional malware family, and no sandbox supplied a separate malicious verdict. No complete host-reputation result is available, but the confirmed hacktool evidence is independently decisive.
What We Detected
28 of 76 antivirus engines flagged DeltaExecutor.zip, including eight tier-1 engines. ALYac, Antiy-AVL, CTX, and Sangfor supplied corroborating Process Hacker or generic hacktool labels; Kaspersky reported ChromeInject credential-theft behavior, while ESET-NOD32 and Ikarus reported VMProtect-related trojans.
Threat Behavior
A completed sandbox run mapped activity to T1055 process injection and T1562.001 impairment of defenses. The recorded execution included rundll32 loading a DLL from a temporary directory, which supports the process-injection concern. The archive also carries debug-environment detection and long-sleep tags, both commonly associated with analysis evasion. No complete contacted-host reputation check is available, and the ten inspected child files remained unclassified rather than confirmed benign.
What To Do Now
Do not extract or run the archive. Quarantine or delete it while keeping antivirus and endpoint protection enabled; if it was already executed, disconnect the affected system from sensitive accounts and networks, run a full scan, and review credentials used on that machine.
Where this verdict could be wrong4 caveats
- engines.tier1FamilyConsensus.strong=false; only two tier-1 engines converged on VMProtect, which is also a commercial protector rather than a malware family.
- behaviour.hasMaliciousSandboxVerdict=false, and the single completed sandbox recorded no contacted domains, IPs, or URLs.
- droppedChildren.hasMaliciousChild=false, although all 10 inspected children retained unknown verdicts rather than confirmed benign results.
- externalIntel.yaraify.ruleCount=0, externalIntel.circl.hit=false, and externalIntel.malwareBazaar.hit=false.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- behaviour.hasMaliciousSandboxVerdict=false
- No domains, IPs, or URLs were recorded during the single sandbox run
- droppedChildren.hasMaliciousChild=false, though all 10 children remained unknown
- externalIntel.yaraify.ruleCount=0
- brandMismatch was not detected
- 28/76 antivirus detections
- Eight tier-1 engines flagged the archive
- Confirmed Process Hacker and generic hacktool labeling
- T1055 process-injection evidence
- T1562.001 defense-impairment evidence
- rundll32 loaded a DLL from a temporary directory
Quarantine or delete the archive and do not execute its contents. If it has already run, keep endpoint protection enabled, perform a full system scan, and rotate credentials accessed from the affected machine.

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: Attempted to impair or bypass security controls.
Moderate concern: Removed execution artefacts or logs, which can conceal activity.
Moderate concern: Communicated over a common application protocol; malware can use this for command-and-control.
Moderate concern: Checked the environment for virtualisation or analysis tools.
Note: Listed running processes; both legitimate software and malware may do this.
Note: Collects details about your system.
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.
The 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.
