Dangerous malware CryptoLocker holds data ransom

What is CryptoLocker?

CryptoLocker is a ransomware program that will encrypt certain files such as Microsoft Word, Powerpoint, Excel, Pictures, Music, Videos, etc.  When it has finished encrypting your files, it will display a CryptoLocker payment program that prompts you to send a ransom order to decrypt the files.

What computers are at Risk?

Microsoft Windows systems running Windows 8, Windows 7, Vista, and XP operating systems.

Why it it dangerous?

Your data files are encrypted with a unique key that only the hackers have access to.  The encryption cannot be broken at this point in time without the key.  When your data is encrypted and the key is lost, the data is essentially lost forever.

What if I think my computer is infected?

  1. Disconnect the computer immediately from ALL networks; wired or wireless
  2. Contact the UA Support Center 330.972.6888

How can I protect my computer?

  2. Do not follow unsolicited web links in email or open email attachments that you don't expect; even if they are from people you know.
  3. Follow safe practices when browsing the web; see the section below on Good Security Habits.
