The TXT_ALIEN Leak Gave Hackers Keys to 18 Million Stolen Accounts

HEROIC analysts uncovered TXT_ALIEN - 1064, one of the largest stealer log dumps in this batch, uploaded by a Telegram user and dated July 3, 2025. The "Alien" branding points to a well known family of information-stealing malware used to harvest credentials at scale, and this particular file backs that up with 17,964,850 records, nearly 18 million email addresses paired with plaintext passwords and the exact URLs those logins unlock.

The TXT_ALIEN Leak Gave Hackers Everything They Need

With almost 18 million working login combinations in one file, criminals do not need to do any additional work to start using this data. Every record already includes the site the credentials belong to, so attackers can skip straight past the reconnaissance stage and begin testing logins on real accounts immediately. A leak of this size gives whoever holds it the raw material for large-scale account takeover campaigns, credential stuffing attacks, and resale to smaller criminal groups looking for fresh targets.

What Was Exposed in the TXT_ALIEN Dump

• Email addresses connected to real accounts
• Plaintext passwords with zero encryption protecting them
• URLs revealing the exact site or service each login unlocks

Why This Matters When Nearly 18 Million Records Are Involved

At this scale, even a tiny success rate turns into hundreds of thousands of compromised accounts. Attackers plug these login pairs into automated tools that hammer banking portals, email providers, and shopping sites simultaneously, looking for any password that still works. Anyone who resued a leaked password on another account faces the same risk, even if their original account had nothing to do with the initial infection. This is exactly how a single stealer log campaign snowballs into widespread identity theft and financial fraud.

How Alien-Branded Stealer Logs Reach This Scale

Alien style stealer malware infects devices through phishing emails, cracked software, and malicious downloads, then silently pulls every saved password and autofill entry out of the victim's browser. Operators running large campaigns infect thousands of machines before compiling everything into a single massive text file, exactly the kind of volume seen in TXT_ALIEN - 1064. Numbered file names like this one usually indicate a series, meaning this may not be the only large batch this particular operation has released.
