Is td-setup-win-x64-7.2.9.exe safe?
No antivirus engine detected malware, the Telegram FZ-LLC signature verifies, and covered host and child-file checks found no corroborating threat.
All 75 antivirus engines avoided a detection, including 17 tier-1 engines, and the executable carries a verified Telegram FZ-LLC signature. One sandbox mapped several offensive techniques, but it produced no malicious verdict, while covered network hosts and inspected child files yielded no known threats.

Before installing
Install it only when it came from the developer's official site or an official app store.
If you already installed it
Keep normal device protection enabled and stop if the file behaves unexpectedly.

The reasoning behind this verdict
This section explains the evidence supporting the verdict and keeps conflicting or missing signals visible.
All 75 antivirus engines avoided a detection, including 17 tier-1 engines, and the executable carries a verified Telegram FZ-LLC signature. One sandbox mapped several offensive techniques, but it produced no malicious verdict, while covered network hosts and inspected child files yielded no known threats.
The strongest evidence is the complete absence of detections across 75 antivirus engines, including all 17 tier-1 participants. The executable is signed and verified by Telegram FZ-LLC, with no detected mismatch between the claimed product and signer. A completed sandbox run mapped T1055, T1485, and T1548, but did not produce a malicious verdict or identify persistence. Reputation checks covered all seven contacted IP addresses and found no known malicious or suspicious hosts, while ten inspected child files produced no malicious finding. Broad submission prevalence and a prior same-imphash, same-signer Telegram installer further support ordinary commercial software, though the limited signer history prevents maximum confidence.
What We Detected
No malware or suspicious detections appeared among 75 antivirus engines, including 17 tier-1 engines. The executable has a verified Telegram FZ-LLC signature, and no brand mismatch was detected. A prior Telegram installer sharing this imphash and signer also received a favorable assessment.
Threat Behavior
One sandbox run observed installation activity and network communication associated with Telegram infrastructure. It mapped T1055, T1485, and T1548, including a possible process-injection signal involving Explorer, but did not issue a malicious sandbox verdict. Reputation coverage included all seven contacted IP addresses and found no known malicious or suspicious hosts; ten inspected dropped files likewise produced no malicious child finding.
What To Do Now
Use the installer only if it came from Telegram's official distribution channel and its signature still verifies as Telegram FZ-LLC. Keep endpoint protection enabled and obtain a fresh official copy if the download source or signature differs.
Where this verdict could be wrong3 caveats
- behaviour.offensiveTechniques includes T1055, T1485, and T1548; the T1055 process-injection mapping is a meaningful counter-signal, although the sandbox did not issue a malicious verdict.
- signing.signerStats.totalSamples=1, so the publisher-history record is too small to establish long-term trust.
- The sample was first observed only 14 days ago, although prevalence.uniqueSources=1759 indicates broad distribution.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- 0/75 antivirus engines reported a detection.
- All 17 tier-1 engines reported no detection.
- Verified signature from Telegram FZ-LLC with no brand mismatch.
- All seven contacted IP addresses had no known malicious or suspicious reputation.
- Ten inspected child files produced no malicious child finding.
- Sandbox evidence mapped possible process injection to MITRE T1055.
- Additional offensive mappings include T1485 and T1548.
- Publisher history contains only one earlier sample.
- The file was first observed 14 days ago.
Confirm the Telegram FZ-LLC signature and download origin before installation. Keep antivirus and endpoint protection enabled.

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.
