MTD March 2017 Ransomware • Aer paying the ransom, some victims have been asked to pay even more to get the encryption keys. (Surprisingly, the dealer said he was told by a number of IT people there is some honor among cyber thieves.) • Paying ransom supports and encourages this illegal activity. e U.S. government does not encourage paying the ransom, but doesn't prohibit it, either. "Whether to pay a ransom is a serious decision requiring the evaluation of all options to protect shareholders, employees and customers." Prevent defense "As with other forms of malware, security soware might not detect a ransomware payload, or, especially in the case of encrypting payloads, only aer encryption is under way or complete, particularly if a new version unknown to the protec- tive soware is distributed," says Croswell. "New categories of security soware, specifically deception technology, can detect ransomware. Deception technology can detect ransomware and notify cyber security teams, which can then shut down the aack and return the organization to normal operations." Using soware or other security policies to block known payloads from launching will help to prevent infection, but will not protect against all aacks, he says. "ere are several tools intended specifically to decrypt files locked by ransomware, although successful recovery may not be possible. To help prevent being hacked and held for ransom, Croswell suggests the following eight preventive measures: 1. Make sure you have updated antivirus soware on your computer. 2. Enable automated patches for your operating system and web browser. 3. Have strong passwords, and don't use the same passwords for everything. 4. Use a pop-up blocker. 5. Only download soware — especially free soware — from sites you know and trust (malware can also come in downloadable games, file-sharing programs, and customized toolbars). 6. Don't open aachments in unsolicited emails, even if they come from people in your contact list, and never click on a URL contained in an unsolicited email, even if you think it looks safe. Instead, close out the email and go to the organization's website directly. 7. Use the same precautions on your mobile phone as you would on your computer when using the internet. 8. Conduct regular system back-ups, and store the backed-up data offline. 'You think you're smart enough to run your business.' 28
