Total breached databases
In 2019, a data breach involving Telegram users' information was reported. The breach exposed a database containing phone numbers and unique Telegram user IDs, which was shared on darknet forums. The data was primarily collected before mid-2019, with about 84% of it being outdated and around 60% inaccurate. The majority of the affected accounts were from Iran (70%) and Russia (30%).
The breach was attributed to the app's built-in contact export feature, which allows users to see which of their contacts are also using Telegram. This feature can be exploited by malicious users to build databases matching phone numbers with user IDs.
