Is steam_api.dll safe?
This unsigned Steam-related DLL is confirmed crack tooling, with 38 of 75 engines flagging it and runtime evidence mapping activity to process injection.
The DLL is identified as crack or hacktool software by multiple engines, including ESET-NOD32, while Microsoft and other vendors apply trojan labels. One completed sandbox run mapped activity to T1055 process injection, and the file has no authenticated publisher to offset those findings.

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 identified as crack or hacktool software by multiple engines, including ESET-NOD32, while Microsoft and other vendors apply trojan labels. One completed sandbox run mapped activity to T1055 process injection, and the file has no authenticated publisher to offset those findings.
Thirty-eight of 75 engines flagged the sample, including six independent tier-1 detections. ESET-NOD32 specifically identified Win32/HackTool.Crack.EE, while additional engines corroborated crack-tool labeling, satisfying the confirmed-hacktool criterion. A completed sandbox run mapped activity to T1055 process injection and recorded execution through rundll32.exe. The file is unsigned and has no established signer history. Although it is old and commonly submitted, and no sandbox supplied an explicit malware verdict, those mitigating points do not outweigh the confirmed offensive-tool classification and broad engine detections. Reputation for the observed IP was not fully checked because no complete contacted-host result is available.
What We Detected
38 of 75 antivirus engines flagged this unsigned Win32 DLL. Six tier-1 engines detected it, with ESET-NOD32 naming Win32/HackTool.Crack.EE, Fortinet naming Riskware/Crack.A, and Microsoft naming Trojan:Win32/Skeeyah.A. Multiple corroborating crack-tool labels make this more than an isolated generic alert.
Threat Behavior
One completed sandbox observation mapped activity to MITRE T1055, Process Injection, and recorded execution through rundll32.exe. The sample also wrote files beneath C:\ProgramData\SkidRow. It contacted the IP address 204.79.197.203, but no complete host-reputation result is available, so that connection cannot be characterized as benign or malicious from this evidence.
What To Do Now
Do not load or distribute this DLL, particularly as part of a game crack or modified Steam installation. Keep endpoint protection enabled, quarantine the file, remove the associated cracked software, and obtain the game or application from its official distribution channel. If the DLL already ran, perform a full system scan and review related processes and files.
Where this verdict could be wrong4 caveats
- prevalence shows 599 submitters and 648 submissions since 2015, indicating this is an old, widely encountered sample rather than a newly observed file.
- behaviour.hasMaliciousSandboxVerdict=false, although the completed run still recorded T1055 and this field alone does not establish benign behavior.
- externalIntel.yaraify.ruleCount=0 and externalIntel.circl.hit=false provide no researcher-curated corroboration, but absence of those hits may reflect coverage limits.
- Nine tier-1 engines reported no detection, and the tier-1 crack-family agreement is only 2 engines rather than a strong family consensus.
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 sample has been observed since 2015 and submitted 648 times
- Nine tier-1 engines reported no detection
- No explicit malicious sandbox verdict was recorded
- No malicious dropped child was identified
- CIRCL and YARAify returned no corroborating hit
- 38/75 antivirus detections
- Six tier-1 engine detections
- Confirmed crack/hacktool labeling
- T1055 process-injection mapping
- Unsigned Win32 DLL
- Execution through rundll32.exe
Quarantine and remove the DLL and any associated crack package while keeping endpoint protection enabled. If it was executed, run a full scan and reinstall the affected software from an official source.

What this file does
Observed actions and their security significance
High concern: Injected code into another process, a technique that can conceal execution.
Moderate concern: Contained obfuscated or packed code that makes inspection harder.
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.
Moderate concern: Checks which security software you have installed.
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.
Evidence"C:\Windows\System32\rundll32.exe" "C:\Users\<USER>\Desktop\library.dll",#1The 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.

What to do now
This file is dangerous. Treat it as harmful and remove it.
- Recovery step 01
Don't use this component. 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.
- Recovery step 02
If you already used it, disconnect from the internet and start with a full antivirus scan or Microsoft Defender Offline scan. If compromise is suspected or the problem persists, use a reputable second-opinion scanner and follow incident-recovery or clean-reinstall guidance.
- Recovery step 03
If you typed any passwords while it was open, change them from a device you trust.
- Recovery step 04
Reinstall the parent software from the developer's official site instead of replacing this component by itself.
