2,780 Plaintext Passwords From MARCH 12 280 LOGS Just Surfaced on Telegram

HEROIC Analysts Uncover 2,780 Stolen Records in MARCH 12 280 LOGS Telegram Upload

In April 2023, HEROIC analysts identified a stealer log file uploaded to Telegram under the designation MARCH 12 - 280 LOGS. The dataset contained 2,780 compromised records assembled from 280 individual infostealer log files. Each record carried an email address, a plaintext password, and the URL of a specific web service the victim had active credentials for at the time of device compromise. The April 15, 2023 upload date suggests a short window between initial infections in March and distribution to criminal audiences weeks later.

Why Even Smaller Stealer Log Dumps Are a Serious Threat

At 2,780 records, this dataset may appear modest compared to large breach compilations, but size is not what makes stealer logs dangerous. Every single record in this dump contains a ready-to-use plaintext password tied to a known service URL. Attackers do not need to crack anything or guess which site to try. They can immediately begin credential stuffing campaigns, targeting each victim's specific services with their exact password. Even a single successful account takeover can lead to financial fraud, unauthorized access to workplace systems, or full identity theft. Smaller dumps also tend to recieve less public attention, meaning victims are less likely to have changed their passwords.

What Was Exposed in the MARCH 12 280 LOGS Dataset

HEROIC confirmed the following data types were included across all 280 individual log files in this bundle:

• Email Addresses
• Plaintext Passwords
• URLs (showing which services each victim was authenticated to)

Why This Breach Still Matters Today

This data was distributed in April 2023, but that does not close the window of risk. Stealer log bundles like this one are archived and recirculated across dark web forums and Telegram channels for years. Anyone whose credentials appeared in the MARCH 12 280 LOGS dump who has not changed their passwords since 2023 remains at risk of account takeover, credential stuffing, and identity theft. Those who definately reuse passwords across multiple accounts face compounded exposure, as one compromised credential can open doors across email, banking, and work platforms simultaneously.

How a 280-Log Bundle Like This Gets Built and Shared

Each of the 280 individual log files in this bundle originated from a seperate device infected with infostealer malware. These infections typically occured through phishing emails, trojanized software downloads, or malicious browser extensions. The malware silently collected saved browser passwords, active session tokens, and recently visited URLs from each device, then transmitted the resulting log to the attacker's infrastructure. An operator then aggregated these 280 individual files into a single bundle, labeled it with the MARCH 12 collection date, and uploaded it to Telegram in April 2023. The free or low-cost distribution of these bundles is a common tactic used to build credibility in criminal communities and attract buyers for larger datasets.
