Executive Summary
In May 2024, about 2 billion rows of credential data with 361,468,099 unique email addresses were collated from 518 malicious Telegram channels (1,748 files, ~122GB). The data included email addresses, usernames, passwords, and in many cases the website the credentials were entered into, sourced from a mix of combolists and infostealer malware. About 151 million email addresses had not been seen before.
ObscureIQ assessment: Because much of the data came from infostealers, presence may indicate a device was infected, so exposure can extend to any credential typed on that device, not just one account.
Breach Impact
The inclusion of the target website alongside credentials makes this especially useful for precise credential-stuffing and account-takeover attempts; presence indicates credentials are actively circulating for reuse attacks.
About Combolists Posted to Telegram
This record is an aggregation of credential combolists harvested from malicious Telegram channels rather than a breach of a specific organization.
Why They Hold Your Data
Telegram-distributed combo lists usually contain email-password or username-password pairs compiled from prior incidents and repackaged for easy sharing in messaging channels. The workflow is not service delivery but redistribution, where credentials are collected, formatted, and circulated in batches for rapid downstream use.
Recent Developments
Collated in May 2024 from 518 Telegram channels, the data combined existing combolists with output from information-stealing malware.
