Password Brute Force Attacks Threaten Millions of App Users

In September of 2014, private photos of a number of celebrities, including Kate Upton and Jennifer Lawrence, were leaked onto the image-based bulletin board 4chan. It was soon discovered that this leak occurred as a result of a bruteforce attack against Apple’s iCloud, which until then had not limited the number of login attempts for each user account.

Hackers exploited this oversight via the use of a password-breaking tool known as iBrute, which enabled them to gain unauthorized access to several celebrities’ accounts and steal their private photos from available data backups. This type of attacks also affects online accounts stored on users’ mobile devices, as a recent study conducted by AppBugs reveals. Read more...

Security Awareness Tip

Understanding Denial-of-Service Attacks

How do you know if an attack is happening?

Not all disruptions to service are the result of a denial-of-service attack. There may be technical problems with a particular network, or system administrators may be performing maintenance. However, the following symptoms could indicate a DoS or DDoS attack: 

  • unusually slow network performance (opening files or accessing websites)
  • unavailability of a particular website
  • inability to access any website
  • dramatic increase in the amount of spam you receive in your account


What do you do if you think you are experiencing an attack?

Even if you do correctly identify a DoS or DDoS attack, it is unlikely that you will be able to determine the actual target or source of the attack. Contact the appropriate technical professionals for assistance.
