Before running
Run it only when it came from the developer's official site or another source you independently trust.
If you already ran it
Keep normal device protection enabled and stop if the file behaves unexpectedly.
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 file is a freshly released Telegram Desktop setup executable. It carries a valid signature from Telegram FZ-LLC, shows no malicious detections across 75 engines, and matches expected prevalence for a new public release.
Zero malicious detections from 75 engines, including 16 tier-1 engines, combined with a verified signature from the legitimate publisher, strongly indicate the file is clean. The installer exhibits typical setup behaviour and drops expected Telegram components. While sandbox logs show process-injection and LSASS-related activity, these are common in complex installers and are not corroborated by any malicious verdict or host reputation hits. The single similar-hash result also returned safe.
What We Detected
75-engine scan returned zero malicious or suspicious flags. The executable is signed and the certificate chain validates to Telegram FZ-LLC. Prevalence data shows rapid, broad distribution consistent with an official release.
Threat Behavior
Sandbox execution recorded MITRE techniques T1055, T1485 and T1548 plus direct-IP traffic, but no malicious sandbox verdict was issued and no complete contacted-host reputation result was available cache. Dropped children are all unknown and none flagged malicious.
What To Do Now
The installer can be executed normally. Keep Windows Defender and other endpoint protection enabled; no additional action is required.
Where this verdict could be wrong1 caveat
- Sandbox recorded MITRE T1055, T1485, T1548 and direct-IP connections; these techniques can appear in legitimate installers but still warrant caution.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- Verified digital signature from Telegram FZ-LLC
- Zero detections across 75 engines
- High submission volume matching official release pattern
Run the installer as usual; the evidence indicates the file is the legitimate Telegram Desktop setup package.

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.
EvidenceC:\Windows\Explorer.EXESandbox observed process activity targeting LSASS (Windows credential store). Legitimate software has no business reading LSASS memory — this is Mimikatz-shape behaviour.
EvidenceC:\Windows\system32\lsass.exeThe 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.
