The SIMEC Leak Happened in June 2024. The Passwords Were Plaintext.

HEROIC analysts identified a database leak tied to SIMEC, an Italian industrial and mechanical engineering company, dated to June 17, 2024. The exposed file contains 4,703 identified records, including full names, email addresses, phone numbers, birthdays, gender, and plaintext passwords.

Why This Is Dangerous

This leak happened over a year ago, which means the passwords inside it have had plenty of time to circulate quietly before landing in front of HEROIC analysts. Worse, these are not password hashes that need cracking, they are plaintext, readable the moment someone opens the file. Paired with a birthday, gender, and full name, this is enough personal detail to answer many account security questions or convince a victim that a phishing message is legitimate.

What Was Exposed

• Email addresses
• Phone numbers
• First and last names
• Gender
• Birthdays
• Plaintext passwords

Why This Matters

Time is exactly what makes plaintext password leaks dangerous. The longer a leak like this circulates unnoticed, the more chances an attacker has to test these credentials against other services through credential stuffing, or to use the birthday and personal details for identity theft and account recovery scams. If any of the 4,703 people in this file are still using the same password today, that account is still exposed right now, not just back in 2024.

How Database Breaches Happen

This is classified as a database breach, indicating direct unauthorized access to SIMEC's systems rather than malware on individual devices. Industrial and manufacturing companies are frequently targeted because their web platforms often run on older infrastructure with fewer security updates than consumer-facing sites. A breach of this kind typically starts with an unpatched vulnerability or a stolen administrator login, giving an attacker a direct path to the full customer database, plaintext passwords and all.

Check If You Are Affected

Do not assume this leak is old news just because it happened in 2024. HEROIC's free breach scanner checks your email against more than 400 billion exposed records, including this one, so you can find out today whether your password is still sitting in plaintext somewhere it should not be.
