Since its launch as an anonymous chat application in 2013, Telegram has attracted many cybercriminals. It evolved into a platform that hosts a large volume of illicit content, some of which originates from the dark web. The platform is used for a wide variety of illegal activities and many cybercriminals use it as a preferred platform to conduct their activities.
How Telegram became a safe haven for threat actors
After Edward Snowden revealed government surveillance, Telegram was launched in 2013 with the mission to protect private conversations and data from third parties (such as governments). Later on, after the WhatsApp privacy policy scandal in 2021, Telegram became one of the trending apps to replace WhatsApp, while its high privacy standards attracted brand-new users and threat actors.
Unsurprisingly, features such as full anonymity, including the ability to forward messages anonymously and the ability to set up a username in order to protect users’ phone numbers, made it one of the top chat applications of choice for many criminals.
What type of illicit content can be found on Telegram?
Among the main illegal activities that take place on Telegram, you can find:
- Hacking – trade, and discussion of hacking-related topics, including malware, vulnerabilities, and ransomware.
- Data loss – Compromised data of brands or individuals that is offered for sale.
- Financial fraud – Stolen accounts, stolen credit cards, fake money, and tutorials to help other financial fraudsters.
- Drug and illicit traffic – Including vendors who trade in prescription drugs, weapons, and other illegal products.
- Radical and extremist discussions – Terror and extremist discussions, racist content such as right-wing movements, neo-Nazis, and radical Islamic groups.
With more dark web content posted on Telegram, many dark web threat actors such as hacker groups and ransomware groups operate on Telegram in addition to their original platforms, such as their own sites on Tor.
An example of that is Arvin Club, a ransomware group that has its own website and has lately joined Telegram too, where it opened its own channel:
There are many popular and active groups and channels among threat actors and cybercriminals.

The following example is just one of many malicious posts that are written in the group on a daily basis. The hacker shares an Exploit for LPE (Local privilege escalation) in ZoneAlarm antivirus.
This is a security issue in Check Point’s free edition of ZoneAlarm antivirus and firewall solution that allows a user with limited rights on the machine to inject and execute code with the highest privileges. In simple words – the hacker enters the remote machine with limited user rights, and with the exploit, he gains admin rights in the machine – which can cause serious damage, data breach for example.

How is this information helpful for monitoring illicit activities on Telegram?
Although some of these Telegram groups and channels are technically open to the public, a large number of these groups are closed and their links are usually shared within specific communities. These standards allow many malicious groups to move their activity to Telegram, where they could freely discuss, exchange and even sell data without revealing their identity. While this has positioned Telegram as one of the favorite chatting apps for malicious groups, it has also made monitoring the platform increasingly challenging for law enforcement and security agencies.
