Is OnlineFix64.dll.original.dll safe?
This unsigned DLL has corroborated crack-tool labels, 39 of 75 engine detections, nine tier-1 detections, and a malicious sandbox assessment.
The DLL is consistently identified as a crack or game-hacking component, with 39 of 75 engines flagging it and nine tier-1 detections. A completed sandbox also produced a malicious assessment and observed privilege-related technique T1548, while three matching-imphash samples previously received the same hacktool classification.

Before using
Do not use it. Quarantine this component with your antivirus, then repair or reinstall the parent software from its official source. Do not delete or replace the component manually.
If you already used 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.
The DLL is consistently identified as a crack or game-hacking component, with 39 of 75 engines flagging it and nine tier-1 detections. A completed sandbox also produced a malicious assessment and observed privilege-related technique T1548, while three matching-imphash samples previously received the same hacktool classification.
The strongest evidence is the corroborated hacktool classification: ESET-NOD32 explicitly reports a Crack hacktool, and multiple independent engines use Crack or GameHack labels. Overall, 39 of 75 engines detect the DLL, including nine tier-1 engines, which is far beyond a low-trust false-positive pattern. One completed sandbox returned a malicious assessment and recorded T1548 during execution through rundll32.exe. Three files sharing the imphash previously received malicious hacktool decisions, strengthening the association despite imphash matches not proving exact identity. The file is unsigned, and neither the complete observed-host check nor absent external-intelligence hits outweighs the engine and runtime evidence.
What We Detected
39 of 75 antivirus engines flagged this unsigned Win32 DLL, including nine tier-1 engines. ESET-NOD32 identified Win64/HackTool.Crack.AA, while Fortinet, Malwarebytes, Antiy-AVL, and other engines used Crack, GameHack, or related labels. Microsoft and TrendMicro additionally associated it with Kepavll.
Threat Behavior
One completed sandbox produced a malicious assessment. The DLL was loaded through rundll32.exe, and the observed techniques included T1548, a privilege-related technique considered offensive in this context. The single observed domain was fully checked against the available host cache and was not listed there, but that does not negate the executable-level findings.
What To Do Now
Do not load or execute this DLL. Keep endpoint protection enabled, quarantine or remove the file, and run a full system scan if it was already used; changing important credentials is also prudent if execution occurred on a machine holding sensitive accounts.
Where this verdict could be wrong3 caveats
- contactedHosts inspected the one observed domain and found zero cached malicious or suspicious hosts.
- externalIntel.yaraify.ruleCount=0 and externalIntel.malwareBazaar.hit=false, so those researcher feeds provide no additional corroboration.
- engines.tier1FamilyConsensus is not strong: only 2 tier-1 engines converge on the Crack family.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- The one observed contacted domain had no malicious or suspicious cache match
- No malicious dropped child was recorded
- MalwareBazaar and YARAify returned no hits
- PE analysis did not identify likely packing or high-entropy code
- 39 of 75 engines reported a detection
- Nine tier-1 engines detected the DLL
- engines.hacktoolConfirmed=true
- Completed sandbox returned a malicious assessment
- Offensive MITRE technique T1548 was observed
- The DLL is unsigned
Quarantine and remove the DLL without running it, and keep antivirus protection enabled. If it was executed, perform a full scan and review the system for unauthorized software or account activity.

What this file does
Observed actions and their security significance
High concern: Manipulated how the operating system loads code, which can redirect execution.
Moderate concern: Contained obfuscated or packed code that makes inspection harder.
Note: Reads your Windows user-account details.
Note: Collects details about your system.
Note: Connected to 2 servers during sandbox analysis.
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.
