The OCTOPUS CLOUD Breach Explained: 22,716 Records Exposed

The OCTOPUS CLOUD June 19 drop

On June 19, 2025, an anonymous Telegram user uploaded the archive labeled OCTOPUS CLOUD 300PCS_19.06.2025. The file carried 22,716 credential records pulled from infostealer-infected devices. OCTOPUS CLOUD is one of the higher-volume mid-tier Telegram channels in the Russian-language credential trade, and the 300 PCS label indicates the size of the batch packaging rather than the raw record count.

Where the credentials come from

Each OCTOPUS CLOUD drop is stitched together from hundreds of individual infostealer installations running on victim PCs. Operators collect folders containing browser login data, autofill forms, crypto wallet files, and active session cookies. The operator then filters and repackages the records into a single archive, which is posted to the OCTOPUS CLOUD channel for subscriber download.

What data was exposed

The 22,716 records expose email addresses, plaintext passwords, and the URLs the credentials unlock, including API host endpoints. Because nothing is hashed, attackers can feed the file straight into credential stuffing bots or hand-pick high-value logins for account takeover. Financial services, webmail providers, cryptocurrency platforms, and enterprise SSO portals are all common targets in this archive.

Why the 300 PCS packaging matters

Batches labeled with PCS counts like 300 tell underground buyers how the archive is sorted. Smaller batches typically contain higher-quality, fresher credentials with active sessions, which demands a faster response from defenders. A 300 PCS OCTOPUS CLOUD drop is premium inventory the day it goes live.

Steps to take right now

• Reset every password you saved in a browser during 2024 and 2025.
• Revoke active Google, Microsoft, and Apple sessions.
• Enable multifactor authentication on email, banking, and SaaS.
• Scan all devices for infostealer malware and remove it.
