Search Your Email: The LulzsecCloudLogs Dump Exposed 6,166 Stolen Accounts

What HEROIC Analysts Found in the LulzsecCloudLogs Stealer Log

In August 2023, a Telegram user uploaded a stealer log file identified as LulzsecCloudLogs, exposing 6,166 records harvested from compromised devices. HEROIC analysts identified and indexed this dataset after it appeared in a public channel. The leaked data includes email adresses, plaintext passwords, and URLs, all captured directly from infected machines by infostealer malware before being bundled and shared online.

The 6,166 records in this file represent real people whose active login credentials were silently stolen from their devices. The plaintext nature of the data makes it directly usable by anyone who downloaded the file.

Why Stolen Plaintext Passwords Are Immediately Exploitable

The credentials in the LulzsecCloudLogs dataset require no additional processing. They were captured in plaintext directly from infected devices and are ready to use the moment someone downloads the file. An attacker can begin testing them against email providers, banking platforms, and social media accounts without delay.

The URLs recorded alongside each credential pair give attackers a map of which services each victim was actively using. This removes guesswork from a credential attack entirely. Attackers can focus on the platforms most likely to produce a successful login, increasing the impact of any campaign using this data.

What Was Exposed in the LulzsecCloudLogs Breach

• Email Addresses
• Plaintext Passwords
• URLs (active login services at time of infection)

Why LulzsecCloudLogs Data Is Still Circulating Today

Stealer log files shared on Telegram are downloaded by many people and redistributed across forums, channels, and private groups. The LulzsecCloudLogs dataset has been available since August 2023, meaning it has been incorporated into larger combolists used in ongoing credential stuffing campaigns.

Credential stuffing tools test thousands of login combinations per minute against popular websites. Even credentials from prior years retain value if the account owner has not changed their password. This makes the LulzsecCloudLogs data an ongoing threat for anyone in the dataset who has not updated their security. Account takeover, identity theft, and financial fraud are all realistic downstream risks when plaintext credentials are this widely shared.

How Stealer Logs Like LulzsecCloudLogs Are Created

Infostealer malware is the foundation of datasets like this one. These programs are distributed through phishing campaigns, fake software installers, cracked applications, and malicious browser extensions. Once installed, the malware records browser-saved passwords, session cookies, autofill entries, and the URLs of services the user visits.

All of this data is packaged into a log file and sent to the operator's server. The operator then names the dataset and posts it to Telegram for distribution. The victim generaly has no awarenes this has occured. The malware leaves no visible trace, and the first indication of compromise is typically an unauthorized login noticed weeks or months after the infection took place.

Search Your Email: Find Out If You Were in the LulzsecCloudLogs Breach

If your email adress was active in August 2023 and you have not changed your passwords since then, your credentials may still be circulating from this dataset. HEROIC's free breach scanner searches more than 400 billion exposed records, including stealer log collections like LulzsecCloudLogs, and returns results instantly.

Enter your email in the scanner at the top of this page. If your email appears, change the affected password immediately, enable two-factor authentication on all important accounts, and review your recent login activity for anything unauthorized. Acting now is far easier than recovering from a compromised account later.
