57,324 Plaintext Passwords From t.me Expertlogs 500 Just Leaked

On June 17, 2025, a Telegram channel called Expertlogs 500 published a stealer log file containing 57,324 records of real account credentials. The data included email addresses, plaintext passwords, and URLs indicating which services the affected users were logged into at the time of infection. Files like this one do not sit quietly. They get downloaded, parsed, and fed into automated attack tools within hours of publication. For the 57,324 people whose data appeared in this dump, the clock started ticking the moment that Telegram post went live.

Why This Is Dangerous

Fifty-seven thousand plaintext passwords is not an abstraction. Each one is a working key to at least one account, and probably more, because most people reuse passwords. Attackers who access this file face no technical barrier. There is nothing to crack, no hash to reverse, no encryption to bypass. They load the credentials into a stuffing tool and let it run. Targets include email inboxes, social media accounts, online banking, streaming services, and workplace tools that rely on single sign-on. The Expertlogs 500 label signals this was a numbered series, meaning dozens of similar dumps from the same distributor may already be circulating and accumulatig more victims across the internet.

What Was Exposed

• Email Addresses
• Plaintext Passwords
• URLs (sites and services the compromised users were actively accessing)

Why This Matters

The t.me prefix confirms this file was distributed through Telegram's public channel infrastructure, meaning anyone could find and download it without any special access or payment. Public Telegram stealer logs represent one of the fastest-moving categories of stolen credential data because there is no friction between the attacker posting the file and every threat actor in the world receiving it. The Expertlogs 500 dump joins a long chain of similar numbered releases, collectively representing a sustained credential harvesting operation targeting general internet users. With 57,324 records in a single batch, the operators of this channel are clearly running at industrial scale, making this not an isolated incident but part of a broader, ongoing threat.

How Stealer Log Breaches Work

Infostealer malware is typically spread through pirated software, fake game cheats, malicious browser extensions, or phishing pages designed to look like legitimate download sites. When a user installs the infected software, the malware silently activates in the background and begins harvesting credentials from the device. It reads saved passwords from every major browser, captures autofill data, exfiltrates session cookies, and records API tokens stored in configuration files. All of this is organized into a structured log file and sent to the operator. The operator then batches these logs by count or region and releases them through channels like Expertlogs 500, which apparantly publishes hundreds of such files numberd sequentially.
