Why do you need Telegram monitoring?

Catch Credentials at the Source

Stealer logs reach Breachsense within hours of appearing in a Telegram channel. Monitor for your employee and customer credentials where they first appear, then reset them before attackers log in.

Know When You or a Vendor Is Hit

Monitor your domains and your vendors’ domains. When a ransomware group lists your company or a vendor as a victim, our alert names the group and the victim. You find out once Breachsense collects the group’s post, instead of weeks later in a disclosure email.

Feed Alerts Into Your Stack

We send Telegram findings as webhook or email alerts. Route them into your SIEM, SOAR, or ticketing system to trigger password resets and incident response workflows automatically.

Why Criminal Telegram Channels Are Hard to Track

Criminal Telegram channels are hard to track because Telegram keeps blocking them. Any list of criminal channels goes out of date quickly. Telegram says it blocks tens of thousands of groups and channels every day. By October 13, Telegram had blocked 27,742,322 groups and channels in 2026, according to its moderation page.

Of the 1,057 channels on deepdarkCTI’s public list of Telegram threat actor channels, 659 are now offline or expired.

Stealer logs we indexed before Telegram blocked a channel stay searchable through our API. Besides keeping a channel list current, monitoring stealer logs yourself means processing millions of records a week, as our collection methodology explains.

Monitor Telegram Yourself or Use a Monitoring Service?

Use a monitoring service if you need to track Telegram channels continuously. Joining channels yourself suits one-off research, such as checking a single leak an analyst has heard about.

We Monitor Criminal Channels

We collect stealer logs and threat actor posts from criminal Telegram channels and check each new record against your watchlist.

Get Webhook or Email Alerts

We send each match to the webhook or email address you set for the matching item on your watchlist.

Reset Credentials & Respond

Your team resets each leaked password and revokes the affected employee’s sessions. Breachsense doesn’t change passwords.

Example Breachsense webhook alert in JSON for a stealer log credential, showing the monitored asset, the endpoint, the username, a masked password, the malware family, the infection date and the date found.

Frequently Asked Questions

Telegram monitoring is the continuous tracking of criminal Telegram channels for your exposed credentials, stolen data, and mentions of your organization. When a match appears, you get an alert so you can reset passwords and revoke sessions before attackers exploit the data. It’s one part of broader dark web monitoring.
Criminals use Telegram for its privacy. An account signed up with a burner phone number doesn’t lead back to the person using it. Private channels only admit people who have the invite link. Criminals use Telegram channels to trade infostealer logs, sell network access, share combo lists, and announce ransomware victims.
Breachsense monitors criminal Telegram channels for leaked credentials, leaked session tokens, combo lists, infostealer logs, and network access for sale. You can search by domain, email or IP address. Because most of this data comes from infostealer logs, the passwords are already in plaintext, so you know exactly what’s at risk.
Telegram monitoring focuses on criminal activity on Telegram specifically, which sits between the open web and the dark web. It’s part of a complete dark web monitoring program that also covers hacker forums, ransomware leak sites, and stealer log repositories. Breachsense covers all of these sources together.
Breachsense sends alerts as a JSON webhook into your SIEM or SOAR, or as an HTML email to your security team. Each alert names the watchlist item that matched and the type of exposure. A stealer log alert also includes the username and plaintext password. When the stealer log records the malware family and infection date, the alert includes both.
Breachsense checks criminal Telegram channels continuously, so there’s no scan schedule to set. New stealer logs are indexed within hours of appearing in a channel. How soon we send the alert after a stealer log is indexed depends on your package. Each alert includes the date we found the stealer log.
No. Breachsense collects stealer logs and threat actor posts from criminal Telegram channels, so your team doesn’t need Telegram accounts inside those channels. When a new record matches a domain or email address you added through our API, we send you an alert. Your analysts don’t have to download or open a stealer log themselves.
