Plutonium Stealer Log Hits 29,351 Logins Across Industries
In March 2026, HEROIC analysts uncovered a stealer log labeled "477-71K_plutonium," shared by a Telegram user on 10 March 2026. The file held 29,351 records made up of email addresses, plaintext passwords, and the URLs of the sites each login was tied to.
Which Industries Show Up in the Plutonium Leak
Because the log includes the exact URL for every stolen login, it captures credentials from a wide mix of industries rather then just one company. Stealer logs like this typically touch banking portals, online retailers, social media platforms, gaming accounts, and personal email providers all in the same file.
That spread makes the data more valuable to criminals, since a single log can be resold in pieces to buyers who specialize in different industries, from financial fraud to account resale.
What Was Exposed
- Email addresses
- Plaintext passwords
- URLs of the associated login pages
Why This Matters
No matter which industry a stolen login belongs to, the same risks apply. Attackers use these email and password pairs for credential stuffing, testing them across banking, shopping, and email accounts hoping a password was resued, so victims often don't recieve any warning before the damage is done.
A successful match can quickly turn into account takeover, financial fraud, or identity theft, regardless of which sector the original login came from.
How This Plutonium Stealer Log Happened
This kind of log comes from infostealer malware, which infects a device through a cracked download, fake update, or malicious attachment. Once running, it grabs every saved password and site address it can find in the browser, across every industry the victim happened to use.
The result is packaged into a single log file, like the one labeled plutonium here, and sold or shared with buyers on Telegram who sort through it for the accounts they want.
