The folks at Veracode put together this infographic that describes some of the more notable Twitter hacks, or “twacks,” over the recent past. With the news that even venerable USAToday’s account wasn’t safe, it is interesting to see that Twitter has banned the most popular or obvious password combinations (including the evergreen ‘123456’) from use. And yes, you can get even, as Justin Bieber did after his account was compromised, sending 26,000 texts to his tormentor. Shakira and Taylor Swift better watch their own passwords too!
