HEROIC Analysts Link 6,930 Leaked Passwords to DragonCloudFree 380 PCS

HEROIC analysts link a stealer log file, uploaded in July 2024 under the name DragonCloudFree 380 PCS, to 6,930 records pulled straight from infected devices. The file pairs email addresses with plaintext passwords and the URLs those logins were used on. Because this data was harvested silently by malware rather than reported by any service, the only way to know if you're in it is to scan your email.

Why This Is Dangerous

Plaintext passwords need no cracking, no guessing, and no extra tools, they work the moment someone opens the file. Paired with the matching URL, a stolen credential lets an attacker walk straight into whatever account it unlocks. There's no delay between exposure and misuse here the way there sometimes is with encrypted data.

What Was Exposed

• Email Addresses
• Plaintext Password
• URLs

Once a credential set like this circulates, the damage tends to spread quickly. Attackers try the same email and password combination across banking, shopping, and social platforms, counting on reused passwords to open doors far beyond the original site. Some accounts get drained of stored payment details, others get used to launch further scams under the victim's name.

Stealer logs come from malware sitting quietly on a victim's own computer or phone, recording login pages and typed credentials as they happen, then sending that data back to whoever runs the malware. That's different from a company's database being taken, since the infected device is the source, not any single service. It also means the list keeps growing for as long as the infection stays active and undetected.

See If You Were Caught Up in This

Start by taking a moment to scan your email and check whether it shows up in this file or others like it.

• If it does, change passwords immediately on every account tied to that address, prioritizing financial and email logins.
• Scan the device you normally log in from for malware, since the infection that created this file may still be running.

Do this for work email accounts as well as personal ones; both get swept into files like this.
