CRYPTON_LOGS Telegram Stealer: 1,157 Credentials Exposed

HEROIC analysts identified the CRYPTON_LOGS 3rar stealer log circulating on Telegram in March 2023. This release exposed 1,157 records containing email addresses, plaintext passwords, and URLs harvested from infected devices. CRYPTON_LOGS is one of the most prolific stealer log operations tracked in the DarkHive database, with at least 848 confirmed releases across dozens of named variants including numbered batches, country-specific drops, and version series such as CRYPTON_LOGS 2.0. Related releases in this series include: CRYPTON_LOGS 299PCS uploaded by a Telegram User, CRYPTON_LOGS 2.0 uploaded by a Telegram User, and CRYPTON_LOGS 2.0 usa uploaded by a Telegram User.

Why This Is Dangerous

Stealer logs capture live credentials at the moment of infection. Because plaintext passwords are recorded directly from the victim's browser or device, there is no hashing barrier to protect them. Attackers can immediately use these credentials to access email inboxes, banking portals, workplace systems, and any other service where the same password was reused. The inclusion of URLs tells attackers exactly which sites each credential pair belongs to, enabling fast and targeted account takeover without any guesswork.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs (specific sites the victim was logged into)

Why This Matters

CRYPTON_LOGS' scale of nearly 850 documented releases makes it one of the most significant ongoing stealer log operations ever catalogued in the DarkHive database. Credentials from these drops are used for credential stuffing attacks against major platforms, sold for access to corporate networks, and leveraged for financial fraud and identity theft. Victims who appear in one release may appear in multiple batches, compounding their exposure. Because all passwords are in plaintext, criminals can begin exploiting them without any additional processing.

How Stealer Log Breaches Work

Stealer logs are produced by information-stealing malware installed on victims' computers, typically through phishing emails, malicious software downloads, or compromised browser extensions. Once active, the malware silently harvests saved credentials, session cookies, and autofill data, recording the email, password, and URL for every site the victim accessed. These logs are packaged into compressed archives and uploaded to Telegram channels under operator names like CRYPTON_LOGS, where they are sold or freely distributed. The CRYPTON_LOGS operator has released hundreds of variants, including version-numbered and country-targeted batches, pointing to a highly organized criminal infrastructure.
