10359 Records from APRIL 14 804 LOGS Telegram User Leaked in Stealer Log Attack

In December 2023, a Telegram user uploaded a stealer log file publicly labeled "APRIL 14 - 804 LOGS," exposing 10,359 records to anyone on the channel. The timing of this upload, months after the apparent collection date, suggests the data sat in criminal hands before being dropped for free. That gap alone should raise serious concern about how long these credentials may have already been in active use.

Why This Is Dangerous

Free log drops on Telegram are particularly hazardous because they democratise access to stolen credentials. Rather than being sold to a single buyer, the data is instantly available to every member of the channel, some of whom will be running automated credential stuffing tools around the clock. With 10,359 records available, the chances of some of those accounts being reused across multiple services is extremely high.

The presence of plaintext passwords is the most alarming element here. There is no cracking, no rainbow table lookups, and no GPU farms needed. Anyone who downloads this file and finds a match can log in immediatly. Accounts on banking platforms, corporate email, and cloud services are all at risk if users reused these passwords elsewhere.

The URL data accompanying these records helps attackers understand exactly where victims were active online. That context, combined with working credentials, lets bad actors prioritise which accounts are worth targeting first, making this more than just a bulk dump of random data.

What Was Exposed

• Email addresses harvested from infected endpoints
• Plaintext passwords stored or captured by the stealer malware
• URLs of websites and web services visited from compromised machines
• API host information revealing service endpoints
• Device or endpoint identifiers from infected computers
• Browser autofill credentials saved in Chrome, Firefox or Edge
• Login session data associated with visited URLs

Why This Matters

Even at 10,359 records, this breach carries outsized risk because of the credential format. Plaintext passwords make every single record directly actionable, no additional processing needed. Attackers can begin testing these email and password combinations against popular services within minutes of downloading the file, and affected users have no way of knowing until an unauthorised login alerts them or real damage is done.

The "804 LOGS" naming convention in the source label suggests this is one batch among many, implying an organised collection operation rather than an isolated incident. If the same threat actor or group is regularly releasing logs like this, the cumulative exposure is far larger than this single dump indicates, and prior batches may have already been used for targeted attacks.

How Stealer Log Works

Stealer malware typically arrives on a victim's machine through phishing links, trojanised software, or malicious browser extensions. Once installed, it runs quietly in the background and begins harvesting credentials from saved browser logins, form fills, and active sessions. The collected data is bundled into a structured log file and sent to a remote server controlled by the attacker.

The attacker then has several options: use the credentials personally, sell them on underground marketplaces, or as occured here, release them freely on platforms like Telegram. Free releases are often used to build reputation within criminal communities, attract followers to a channel, or simply dump data that has already been monetised. The "APRIL 14" date in the name likely refers to when the original collection batch was compiled, suggesting the attacker held onto this data for months before releasing it.

What makes stealer logs particularly hard to defend against is that the malware bypasses most traditional security controls. It does not need to crack encrypted passwords because it captures them before they are hashed, at the point of entry, which is why recieved wisdom about hashing alone being sufficent protection falls short here.
