4,209 datacloudspace Records Leaked via Telegram Stealer Log

HEROIC analysts uncovered a stealer log file shared on Telegram in July 2023 that exposed 4,209 records from datacloudspace users. Distributed on July 7, 2023, the archive contained email addresses, plaintext passwords, and URLs collected from devices infected with credential-harvesting malware. This dataset, described by its uploader as containing 400 individual logs, represents real endpoint infections where passwords were captured in active use.

The plaintext nature of these passwords removes every defensive barrier between an attacker and a victim's accounts. There is no hash to crack, no encryption to bypass. Combined with the URL data that identifies exactly which services victims were using, this breach gives attackers a ready-to-use toolkit for account takeover across cloud platforms, email services, and any other site where the same credentials were reused.

What Was Stolen From datacloudspace Users

• Email Addresses - primary identifiers for online accounts, enabling direct login attempts and targeted phishing campaigns
• Plaintext Passwords - fully readable credentials captured by malware before browser encryption, requiring zero additional processing to use
• URLs - browsing and service data revealing exactly which platforms and applications each victim was actively using

Protecting Yourself After the datacloudspace Breach

Once stealer log credentials are circulating on Telegram, automated credential stuffing tools pick them up and begin testing them against hundreads of websites within hours. Password reuse is the primary multiplier here: one stolen password can compromise banking apps, work email, cloud storage, social media, and subscription services if the same combination was used across accounts. The URL data in this breach makes the attack even more targeted, because criminals can skip services victims weren't using and go straight for the high-value accounts they know the victim accessed. Social engineering is also a real risk: armed with your email and a list of your services, attackers can craft convincing support impersonations to extract more access from you or people in your organisation.

What to do: immediately change passwords on every account associated with your exposed email, starting with financial and work accounts. Enable two-factor authentication on all important services and monitor for unexpected password reset requests or unfamiliar logins.

Stealer log: The Method Used to Steal This Data

Stealer logs are the output of infostealer malware infections. The malware itself is typically distributed through phishing emails with malicious attachments, fake software download pages, or compromised browser extensions. Once a device is infected, the malware silently scans all browser-stored credentials, session cookies, and auto-fill data, then packages and transmits the haul to the attacker. Passwords captured this way are in plaintext because they're taken directly from the browser's local storage before any network-level encryption is applied. The resulting log file is then sorted and traded on criminal marketplaces and Telegram channels. The datacloudspace dataset, labelled as 400 logs, followed exactly this distribution path before HEROIC identified and indexed it.
