Way back in the day, MySpace was the place to be online. But its legacy now includes one of the largest data breaches of its time, a stark reminder that what happens online can have consequences years later. The breach exposed a massive trove of user account information, impacting hundreds of millions of people who had long since moved on from the platform. It was a classic case of old data coming back to haunt both a company and its former users.
MySpace Data Breach Explained: What Happened?
The MySpace data breach involved the theft of an enormous database containing user login credentials. Discovered in 2016, the breach actually occurred years earlier, around 2013. The stolen data included email addresses, usernames, and weakly protected passwords for accounts created before June 11, 2013. This old data was later found for sale on dark web marketplaces.
When Did the MySpace Data Breach Happen?
The initial data theft is believed to have happened sometime before June 11, 2013. However, the company and the public only became aware of the massive scale of the breach in May 2016, when the stolen data surfaced for sale online.
Who Hacked MySpace?
The identities and motivations behind the MySpace data breach remain unknown. The data was put up for sale on the dark web by a cybercriminal known as "Peace," but this individual was likely just a seller, not the original hacker.
How Did the MySpace Breach Happen?
MySpace never released specific technical details about the attack vector. However, the nature of the compromised data points to a direct compromise of the company's servers, where user account information was stored. The weak password hashing method used at the time made it much easier for attackers to crack the stolen credentials once they had the database.
MySpace Data Breach Timeline
Pre-June 11, 2013: The initial breach occurs, and attackers exfiltrate a massive database of user account credentials.
May 2016: MySpace becomes aware of the stolen user login data after it's made available for sale in an online hacker forum.
May 31, 2016: MySpace publicly discloses the data breach and begins notifying affected users via email.
June 2016: The company invalidates all user passwords for accounts created before June 11, 2013, to protect them from takeover.
Technical Details
The most significant technical failure in this breach was the poor password security. MySpace stored user passwords using the SHA-1 hashing algorithm, but without "salting." Hashing turns a password into a unique string of characters, and salting adds a random value to each password before hashing to make them harder to crack.
Because the SHA-1 hashes weren't salted, attackers could use pre-computed tables (known as "rainbow tables") to quickly reverse-engineer the hashes and reveal the original plaintext passwords. This made the stolen credential database incredibly valuable for launching credential stuffing attacks across the web. Oof.
Indicators of Compromise (IoCs)
No specific Indicators of Compromise, like IP addresses or malware hashes, were ever publicly released in connection with this breach, as the investigation focused on the compromised data itself rather than an active network intrusion.
Forensic and Incident Investigation
After discovering the breach in 2016, MySpace launched an internal investigation and brought in external cybersecurity experts to assist. Their primary focus was understanding the scope of the data theft and invalidating the compromised credentials to prevent account takeovers. The investigation confirmed that the affected data was limited to accounts created on the old MySpace platform.
What Data Was Compromised in the MySpace Breach?
The breach exposed a significant amount of user account information. For each affected user, the following data was compromised:
Email addresses
Usernames
Passwords (stored as unsalted SHA-1 hashes)
Thankfully, no financial information or other government-issued personal identifiers were associated with the stolen MySpace accounts.
How Many People Were Affected by the MySpace Data Breach?
The breach affected a staggering 360 million user accounts. At the time, it was one of the largest data breaches on record, highlighting the massive digital footprint people had left on the once-dominant social network.
Was My Data Exposed in the MySpace Breach?
If you had a MySpace account created before June 11, 2013, it's almost certain your data was part of this breach. You can check if your email address was compromised using the third-party service Have I Been Pwned. MySpace also proactively invalidated passwords for all affected accounts and notified users.
Key Impacts of the MySpace Breach
The fallout from the MySpace breach was widespread, even though the platform was no longer popular.
Credential Stuffing: The primary impact was the risk of credential stuffing attacks. Attackers used the stolen email and password combinations to try to log into other, more valuable accounts (like banking or email) where users had reused the same password.
Reputational Damage: For MySpace, the breach was another nail in the coffin, cementing its image as a relic of a less secure internet era.
User Distrust: It served as a major wake-up call for millions of users about the long-term risks of their digital data, even on services they no longer used.
Response to the MySpace Data Breach
MySpace's response, once it became aware of the breach, was relatively swift.
Public Disclosure: The company issued a public statement on its blog at the end of May 2016, acknowledging the breach.
Password Invalidation: It immediately invalidated the passwords for all accounts created prior to June 11, 2013. Affected users were required to reset their password upon their next login.
Monitoring: The company implemented tools to detect and block suspicious activity on MySpace accounts.
Lessons from the MySpace Data Breach
This breach taught us some valuable lessons that are still super relevant today.
Data Is Forever: Data doesn't just disappear when a service becomes less popular. Companies have a responsibility to protect user data for as long as they store it.
Password Security is Non-Negotiable: Using weak or outdated hashing methods like unsalted SHA-1 is a recipe for disaster. Modern, strong hashing and salting are fundamental.
Don't Reuse Passwords: The biggest danger for users was password reuse. A breach on one site can lead to compromises everywhere else if you use the same credentials.
Is MySpace Safe after the Breach?
MySpace took steps to secure the platform after the 2016 discovery, including invalidating old passwords and migrating to a new, more secure account system. However, the core lesson remains: any data you shared on the old platform was compromised and is likely still circulating in dark web circles.
Mitigation & Prevention Strategies
Whether you're a business or an individual, you can learn from MySpace's mistakes. Here’s how to protect yourself from similar threats.
Multi-Factor Authentication (MFA): Always enable MFA on your accounts. It's the single best way to protect against credential stuffing attacks.
Strong, Unique Passwords: Use a password manager to generate and store unique, complex passwords for every single one of your online accounts.
Security Awareness Training: For businesses, regularly train your team to recognize phishing attempts and practice good security
Patch Management: Keep all systems and software updated to protect against vulnerabilities that attackers could exploit to steal data.
