The sharkcloud Dump: 8,070 Stolen Credentials Hit Telegram in 2022

HEROIC analysts found a stealer log upload attributed to the handle sharkcloud that occured in November 2022 and was confirmed on December 1, 2022. The file, labeled "sharkcloud NOVEMBER 357 PCS," was uploaded to a public Telegram channel and contained 8,070 records pulled from compromised endpoints. Each record included an email address, a plaintext password, and associated URLs that reveal which services the infected user was logged into at the time the malware ran. With 8,070 credential pairs circulating freely on Telegram, the potential for account takeover is immediate and ongoing for every person in this dump.

Why This Stealer Log Is Dangerous

The sharkcloud dump is particularly dangerous due to its scale and the format of the stolen data. At 8,070 records, it provides threat actors with a meaningful pool of plaintext credentials -- no cracking, no decryption required. Credential stuffing tools can systematically test each pair against popular services in minutes. The inclusion of URLs identifies which platforms each victim was actively using, giving attackers a prioritized attack list. Any actor who downloaded this Telegram file in 2022 -- or purchased it from someone who did -- holds a set of potentially still-valid logins that can be tested at any time.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs (showing active service sessions at time of device compromise)

Why This Matters for Victims

Stealer log data does not expire when the initial Telegram post is taken down. These files are copied, archived, and resold across multiple platforms. The 8,070 people in the sharkcloud dump may have recieved no notification of the breach and may still be using the same passwords today. The URLs in the log are especially revealing -- they identify not just that a credential was stolen, but exactly which accounts were live and accessible on those devices. Attackers who know both the login and the target service face essentially no barrier to entry. Password reuse compounds the risk: a single compromised credential can unlock multiple accounts simultaneously.

How Stealer Log Attacks Work

Infostealers are deployed through a variety of vectors including phishing emails, malicious software bundles, and trojanized browser extensions. Once a device is infected, the malware sweeps through saved browser passwords, captures active session tokens, and records keystrokes in real time. Everything collected is assembled into a structured log file and exfiltrated -- either directly to a Telegram channel controlled by the operator or to a staging server for later sale. The sharkcloud operation follows this pattern precisely: device infections across multiple endpoints, credential harvesting, and a batch upload of 357 PC records to Telegram in November 2022. The assembled logs are then freely available to any threat actor who finds the channel. Victims have no clear indication their device was ever compromised, and the data availablility in criminal markets is effectively permanent once uploaded.
