PolySwarm Scanbot

PolySwarm is a threat-detection company whose platform pools verdicts from many scanners at once: established antivirus vendors and smaller specialist engines compete to flag malicious files and URLs. The Scanbot is its front door in Telegram, and the company's own blog announced it in March 2020 and told readers to search for @PolySwarmBot — so authenticity is not in question here, unlike the many anonymous wrappers around public scanning APIs.

There are two ways to use it. In a private chat you send a suspicious file or link and get back the verdict pulled from PolySwarm's platform, which aggregates more than 30 sources. The more interesting mode is in a group: once added, it scans the files and links members share, warns the chat when something is flagged, and — if you give it admin rights — deletes the malicious post. PolySwarm says it first built the bot to protect its own community chats before opening it to everyone, and a company running hundreds of Telegram channels publicly vouched for it at launch.

Keep expectations realistic. The bot speaks English only, public news about it stops at the 2020 launch, and its profile shows fewer than 10,000 monthly users. As with any cloud scanner, whatever you send is uploaded and checked by third-party engines, so do not submit documents with private data.
