32,681 prdscloud passwords exposed in November 2023 stealer log breach

HEROIC analysts identified the prdscloud 978logs stealer log during routine monitoring of Telegram channels that distribute stolen credential data. The file was uploaded by an anonymous Telegram user on November 6th, 2023, and contained 32,681 records extracted from compromised endpoint machines. The data included email addresses, plaintext passwords, and URLs pointing to web services and API hosts. At 32,681 records, this is one of the larger stealer log batches from this distribution window, and the inclusion of API host URLs indicates that some compromised accounts belong to developers, technical users, or services that interact with cloud infrastructure. HEROIC's research team confirmed the dataset's authenticity against its breach record database.

Why This Is Dangerous

The combination of plaintext passwords, email addresses, and API host URLs creates a particularly dangerous exposure. For regular users, the risk is straightforward: anyone with this file can attempt to log directly into their accounts on the identified services without cracking anything. For developers and technical users, the risk is even greater. Exposed API credentials can allow attackers to interact with cloud platforms, consume paid services at the victim's expense, access stored data, or silently exfiltrate information from systems the API controls. Because the credentials are plaintext, there is no delay between someone downloading this log and being able to act on it. The data was made freely available on Telegram, where anyone could download it at no cost.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs (web services and API host endpoints)

Why This Matters

A breach of this size feeds directly into the credential stuffing pipelines that attackers run continuously against major platforms. With 32,681 working email and password pairs, an attacker can run automated login attempts against banking portals, email providers, e-commerce sites, and corporate VPNs. Every successful login is another account taken over. Account takeover leads to financial fraud when stored payment details are exploited, identity theft when personal information is harvested from inside accounts, and can also enable further phishing campaigns against the victim's contacts. When API credentials are included, the downstream consequences can extend to data breaches affecting the users of whatever service that API supports. Seperate investigations into similar stealer log batches have confirmed that credentials from these files are actively reused within days of being posted.

How Stealer Logs Work

A stealer log is the output of infostealer malware that silently runs on an infected computer. The malware is typically delivered through phishing emails, malicious attachments, or fake software downloads. After installation, it scans the device for saved browser passwords, autofill data, session cookies, and any credentials stored in applications. It also monitors keystrokes to capture passwords typed in real time. All of this information is compressed into a log file and sent to the attacker automatically. The prdscloud 978logs file reflects this proccess exactly. The "978logs" designation indicates the batch contained logs from approximately 978 seperate infected machines, each contributing their harvested credentials to the final dataset before being compiled and distributed on Telegram.

Check If You Are Affected

HEROIC has indexed this breach in its database of over 400 billion records, one of the largest collections of breach and stealer log data available for public search. Use HEROIC's free breach scanner to search your email address and find out whether your credentials were included in the prdscloud 978logs leak or any other known breach. If your data appears, change your passwords right away, revoke any API keys that may have been stored on the affected device, and enable two-factor authentication on all important accounts.
