The CLOUDHEAVENLOGS Password3 Breach Put 623,720 Stolen Email and Password Pairs Online

HEROIC analysts identified a stealer log uploaded to Telegram in May 2023 containing 623,720 records. The file, released as part of the CLOUDHEAVENLOGS series under the label Password3, exposed email addresses, plaintext passwords, and the URLs where each credential was captured by infostealer malware. Despite being over two years old, this dataset remains active on dark web channels where it continues to be downloaded and used in automated attack campaigns targeting anyone whose credentials have not been changed since the initial exposure.

Why This Is Dangerous for the 623,720 People in the CLOUDHEAVENLOGS Password3 Breach

Stealer log data does not expire. If your email and password from 2023 are in this file and you have not changed that password, attackers can still use it today to access your accounts. With plaintext passwords, the attacker knows your exact credential. With the URL, they know exactly which site to target. With your email, they can attempt password resets across banking, healthcare, and corporate portals. The risk is immediate for anyone who reused that password, and even historical exposure can resurface when logs are re-indexed and re-distributed on new dark web markets.

Data Exposed in the CLOUDHEAVENLOGS Password3 Stealer Log

• Email Addresses
• Plaintext Passwords
• URLs (the specific websites where credentials were harvested)

From Credential Stuffing to Identity Theft: What Attackers Do With 623,720 Login Pairs

A dataset of 623,720 records is large enough to fuel weeks of automated credential stuffing campaigns. Criminals test these pairs acros banking platforms, e-commerce sites, email providers, and enterprise VPNs. Because password reuse is widespread, even logs from 2023 continue to yield active accounts. Successful logins lead to account takeovers, unauthorized purchases using saved payment methods, identity theft through document access in cloud storage and government portals, and corporate breaches when employee credentials are in the set. Old logs are also frequently re-bundled and sold on new markets, meaning this data has had multiple cycles of criminal use since first appearing in 2023.

What Is the CLOUDHEAVENLOGS Series and How Was This Password3 Archive Assembled?

CLOUDHEAVENLOGS is a multi-part stealer log series distributed through Telegram channels starting in 2023. The Password3 label indicates it is the third installment in a subset focused specifically on credential data. Infostealer malware like Redline, Vidar, and Raccoon Stealer harvest browser-saved passwords from infected machines and package them into structured log files. These logs are then aggregated by operators into numbered series and uploaded to Telegram for free or paid distribution. The CLOUDHEAVENLOGS operation appears to have been a consistent credential reselling effort that bundled infostealer output from multiple affiliate sources into a public archive. The fact that this series reached at least three numbered installments suggests an organized and prolific distributon operation rather than a one-time upload.
