3.6K Hotmail Combolist Leak Puts 2,853 Accounts at Takeover Risk

The "3.6K Hotmail Combo list Full Valid" Leak Lands on Telegram

HEROIC analysts identified a combolist titled "3.6K Hotmail Combo list Full Valid," uploaded by a Telegram user on 28 June 2026. Despite the name, the verified file contains 2,853 records pairing email addresses with plaintext passwords, along with the URLs each credential pair was tied to.

Why This Is Dangerous

The listing was marketed as "full valid," meaning the credentials inside were checked and confirmed to still work before being shared. Because the passwords are stored in plaintext and paired with the exact URL they unlock, an attacker can log straight into a Hotmail account without guessing, cracking, or any extra effort.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs tied to each credential pair

Why This Matters

A working email and password combination is often the first domino in a much larger fall. Because people frequently reuse the same password across banking, shopping, and social accounts, attackers run confirmed combolists like this one against dozens of other services in a process known as credential stuffing. Every account that shares a password with the leaked Hotmail login becomes a target for account takeover, identity theft, and financial fraud.

How Combolists Work

A combolist is a compiled file of email and password pairs, often gathered from older breaches or stealer malware and then tested in bulk against login pages to confirm which ones still work. Lists marketed as "full valid," like this 3.6K Hotmail combolist, have already been through that verification step, which makes them more dangerous and more valuable to buyers on channels like Telegram, since every entry is a confirmed working login rather than a guess.

Check If You Are Affected

With 2,853 verified records from this combolist now in circulation, it only takes a moment to check whether your email was among them. HEROIC's free breach scanner searches more than 400 billion leaked records, including combolists like this one, so you can confirm your exposure and update your password before an attacker gets there first.
