Cloud Users Exposed: Trident_Cloud Stealer Log Leaked 117,365 Records

HEROIC analysts identified a significant stealer log upload on September 11, 2023, attributed to an anonymous Telegram user distributing files tied to the Trident_Cloud infrastructure. The dump contained 117,365 records, making it one of the larger cloud-adjacent stealer log incidents catalogued in that quarter. Each record included an email address, a plaintext password, and one or more URLs pointing to API hosts and login portals. The scale and structure of the data strongly suggest that infostealer malware had been active on a substantial number of endpoints connected to Trident_Cloud services, harvesting credentials before packaging them for distribution on Telegram channels frequented by cybercriminals.

Why This Is Dangerous

Cloud infrastructure credentials are among the most valuable data a threat actor can obtain. When 117,365 email-and-password pairs tied to cloud API endpoints are freely available on Telegram, attackers can attempt to access cloud storage buckets, virtual machines, and hosted applications with zero technical effort beyond running a script. Companies that rely on Trident_Cloud-connected services face the risk of data theft, ransomware deployment, or silent backdoor installation. Individual users face account takeover across every service where they reused these passwords. The inclusion of API host URLs gives attackers a map of exactly which endpoints are worth targeting first.

What Was Exposed

• Email Addresses
• Plaintext Passwords
• URLs (including API host and cloud service endpoints)

Why This Matters

A breach of this size affecting cloud-connected users creates cascading risk. Credential stuffing attacks fueled by this data can compromise not just personal accounts but corporate systems, cloud storage, and developer environments. Identity theft becomes straightforward when an attacker has both an email address and a working password. Financial fraud follows quickly when banking or payment credentials are in the mix. The seperate risk of API key exposure means automated systems and integrations can be hijacked without any human login ever triggering an alert. Because the data was shared openly on Telegram, it was likely recieved and acted upon by multiple threat actors before most affected users had any awareness of the breach.

How Stealer Logs Work

Stealer malware operates by silently installing itself on a target endpoint, typically through phishing lures, trojanized software, or drive-by downloads from compromised websites. Once running, it scans the device for stored credentials in web browsers, password managers, and application config files. It captures active session cookies, saved autofill data, and any API tokens stored in plaintext on the device. All harvested material is compressed into a structured log file and exfiltrated to the attacker's infrastructure, often within minutes of infection. The resulting logs are then traded on underground forums and Telegram channels, where buyers use them for credential stuffing campaigns, account takeovers, and targeted intrusions against high-value targets like cloud platforms.

Check If You Are Affected

With 117,365 records exposed in the Trident_Cloud stealer log from September 2023, a significant number of users and developers are at risk. HEROIC's breach monitoring database covers over 400 billion records, and this incident is fully indexed. Head to heroic.com to search your email address and determine whether your credentials were part of this dump. If your email appears, rotate all passwords immediately, revoke any API keys that may have been captured, and enable multi-factor authentication on every cloud service you access.
