Threat context

How downloaders work

This file is a delivery vehicle. On its own it can look small and harmless, but its job is to quietly pull down and install the REAL payload — often a stealer, ransomware, or bot — from a server the attacker controls.

Bottom line:Because the dangerous part arrives later, early scans can look cleaner than the threat really is.

How many antivirus engines detected onstream-tv-1.1.1.apk?
4 of 75 antivirus engines flagged onstream-tv-1.1.1.apk, 4 of them as outright malicious. The raw count alone does not establish safety or danger; we also weigh which engines flagged it and corroborating behavior, identity, reputation, and rule evidence. The malicious verdict comes from the complete saved evidence, not from this antivirus count by itself.
I already downloaded and installed onstream-tv-1.1.1.apk — what should I do?
Act quickly. 1) Disconnect the device from the internet to stop the malware communicating or spreading. 2) Run a full scan with reputable anti-malware software (such as Malwarebytes) and quarantine everything it finds. 3) Change your important passwords from a DIFFERENT, clean device — many threats log keystrokes or steal saved credentials. 4) If you bank or shop on this device, watch closely for fraud and alert your bank. 5) For a confirmed infection, the most reliable fix is to back up your personal files and reinstall the operating system for a clean start.
How do I remove onstream-tv-1.1.1.apk?
To remove onstream-tv-1.1.1.apk: 1) restart into Safe Mode (Safe Mode with Networking if you need to download a tool) so the malware doesn't auto-start. 2) Run a full scan with reputable anti-malware software and let it quarantine or delete the detections. 3) Delete this app from the device, then empty the Recycle Bin or Trash. 4) Check your browser extensions, startup items, and scheduled tasks for anything unfamiliar. 5) Reboot and scan again to confirm it's gone. If detections keep coming back, a clean operating-system reinstall is the most dependable cure.
What kind of malware is onstream-tv-1.1.1.apk?
onstream-tv-1.1.1.apk is classified as a downloader/dropper whose job is to pull additional malware onto the device. Engines attribute it to the Mamont family. Knowing the family matters because it tells you the likely impact — data theft, remote control, file encryption, or unwanted ads — and guides the cleanup.
What is the SHA-256 hash of onstream-tv-1.1.1.apk?
The SHA-256 hash of onstream-tv-1.1.1.apk is 83c1243cdabe409e0b398f29b89f737d919b4084520cccfd1e19fc5ec508d500, and its MD5 is 4d5eb17c74d9dd2c7f095fd1dcb7a28d. This hash is the file's unique fingerprint — two files with the same SHA-256 are identical. Use it to confirm you're looking at exactly this file (not just one with the same name) when comparing against antivirus databases or a download's published checksum.
How up to date is this analysis of onstream-tv-1.1.1.apk?
This report reflects the scan run on June 18, 2026.
