RedlineClouds1 1450PCS uploaded by a Telegram User

We've been tracking the rising tide of stealer logs circulating on Telegram, but recently, the focus has shifted from quantity to specificity. Threat actors are becoming more adept at targeting specific applications and services, sifting through the noise to extract high-value credentials and API keys. Our team came across one such log file, uploaded by a Telegram user in mid-November, that immediately stood out. What made it notable wasn't the size – a relatively modest 21,025 records – but the clear targeting of cloud service endpoints. The data had been circulating quietly, but we noticed the file contained a concerning volume of credentials for RedlineClouds1, potentially granting unauthorized access to sensitive cloud infrastructure.

RedlineClouds1: 21k Records Exposed in Telegram Leak

A stealer log file, uploaded to Telegram on November 13, 2023, exposed 21,025 records, including email addresses, plaintext passwords, and URLs associated with various endpoints. The breach, dubbed "RedlineClouds1 1450PCS" by the uploader, appears to be the result of an information-stealing malware campaign targeting users of the RedlineClouds1 service. What caught our attention was the inclusion of plaintext passwords, which is a departure from the more common practice of storing password hashes. This greatly simplifies credential stuffing attacks and account takeovers. The exposed data includes credentials used to access API hosts, creating a potential pathway for attackers to compromise cloud infrastructure.

• Total records exposed: 21,025
• Types of data included: Email Addresses, Plaintext Passwords, URLs
• Source structure: Stealer log file
• Leak location: Telegram channel
• Date of first appearance: November 13, 2023

The appearance of this stealer log on Telegram is consistent with a broader trend of such marketplaces becoming increasingly popular among cybercriminals. These platforms offer a relatively anonymous and easily accessible venue for trading stolen credentials and other sensitive data. Security researchers at Group-IB have documented the rise of "Initial Access Brokers" who specialize in harvesting and selling compromised credentials via Telegram and other dark web forums. The fact that the passwords were in plaintext further highlights the severity of this breach and the potential for rapid exploitation.
