“123456” is the world’s worst stolen password, according to security firm Splashdata. The change in leadership is largely thanks to Adobe’s major security breach in October. The magnitude of the breach had a major impact on Splashdata’s results, explaining why “photoshop” and “adobe123″ worked their way onto this year’s list. Weaker passwords are more susceptible to brute-force attacks, where hackers attempt to access accounts through rapid guessing. Instead, consider using phrases of random words separated by spaces or underscores, and using different passwords.”]
