571K Leaked: Smartphone Target 600K combo uploaded by a Telegram User

Dark Web Intel: 571,392 Records in a "Smartphone Target" Combo List

HEROIC analysts flagged a large stealer log titled "Smartphone Target 600K combo," tracing back to a December 2022 collection date and circulating on a Telegram channel. The name suggests the credentials were gathered specifically from smartphone users or mobile-focused services, and the file lives up to its "600K" label, containing 571,392 records made up of email addresses, plaintext passwords, and the URLs those logins belong to.

Why This Is Dangerous

A combo list of this size gives attackers an enormous, ready-to-use collection of working email and password pairs. Because every record includes the exact login URL, there is no guesswork involved, an attacker or automated tool can go straight down the list attempting logins against real accounts. At more than half a million records, the sheer volume makes this a high-value asset for large-scale credential stuffing campaigns.

What Was Exposed

• Email addresses
• Plaintext passwords
• Login URLs

Why This Matters

With 571,392 records in circulation, the risk extends far beyond any single account or website. Reused passwords are especially dangerous here, since automated tools can test each credential pair against banking, email, and shopping sites in bulk, leading to widespread account takeover, identity theft, and financial fraud. The mobile focused targeting also raises the odds that the accounts involved include app based logins tied to personal and financial information.

How a Large Combo List Like This Gets Assembled

Stealer logs and combo lists are built from infostealer malware infections that quietly copy saved browser passwords, autofill data, cookies, and the addresses they belong to from each infected device. When a distributor collects and merges results from hundreds of thousands of infections, often filtering for a specific target group such as smartphone or mobile app users, the result is a combo list like this one: large, targeted, and ready for immediate criminal use.

Check If You Are Affected

Given the scale of this leak, it is worth checking your exposure without delay. HEROIC's free breach scanner checks your email address against a database of more than 400 billion leaked records, including large combo lists like this one, so you can find out quickly if you were affected and change your passwords before an attacker gets there first.
