406,300 Gmail Logins Exposed in the ‘Gmail 26.10’ Stealer Leak

In January 2023, a Telegram user uploaded a stealer log file labeled "gmail 26.10," exposing 406,300 records harvested from infected devices. The name refers to a curated collection of Gmail-linked credentials pulled by infostealer malware, not a breach of Google's own systems. The file itself contains email addresses, plaintext passwords, and the URLs those logins connect to.

Why This Is Dangerous

Because this data was collected directly from infected devices rather than a hacked website, it puts real working Gmail credentials directly into criminal hands. If any of these Gmail accounts double as recovery emails or password reset destinations for other services, one exposed inbox can quickly become the key that unlocks a person's entire online identity.

What Was Exposed in the Gmail 26.10 Leak

• Email addresses
• Plaintext passwords (stored with no encryption)
• URLs showing which sites or services each login connects to

Why This Matters

An exposed email and password pair is prime material for credential stuffing, where attackers run stolen logins against dozens of other sites hoping the same password was reused. If a criminal gets into a Gmail account tied to this leak, it can lead straight to account takeover on other services, identity theft, and financial fraud, since email inboxes are often the gateway used to reset passwords everywhere else.

How a Stealer Log Leak Like Gmail 26.10 Happens

Infostealer malware typically spreads through fake software downloads, cracked programs, or phishing links. Once installed, it quietly pulls saved passwords and autofill data out of a victim's browser, bundling it into a log file organized by the type of account it found, in this case, Gmail logins. These files are then shared or sold on Telegram channels and dark web marketplaces.
