IT Alert – New Threat of Ransomware Reported by State of Texas CISO

Typing on keyboardThe state of Texas Office of the Chief Information Security Officer has been monitoring new infections of dangerous CryptoLocker and CryptoWall ransomware on some state computers. The infections are believed to be spread through malicious emails. One instance of infection is known to have been propagated via an email fax confirmation.

CryptoLocker and CryptoWall are examples of “ransomware” that attackers use to encrypt data on your computer that can only be decrypted by paying the attacker’s fee, i.e. ransom.

The TTU IT Division recommends the following safe computing practices to protect yourself and TTU resources from this and other email scams:

  • Do not click on links contained within an email unless you are certain of the sender’s identity and expecting the information;
  • Do not open attachments unless you are certain of the sender’s identity and expecting the information; Delete and do not reply to any of these emails;
  • Update your desktop, laptop, and/or mobile device anti-virus software; and
  • Keep current on critical system updates:

We encourage you to be vigilant in practicing safe computing. You can find additional Safe Computing tips online at http://safecomputing.ttu.edu. For more information or questions, please contact IT Help Central at (806) 742-HELP (4357) or via email at ithelpcentral@ttu.edu.
