"CryptoLocker" malware threatens Internet Users.
"CryptoWall" and "CryptoDefense"
"CryptoWall" and "CryptoDefense" operate in a similar manner to "CryptoLocker" by encrypting the files on your network shares and denying users access until they pay the ransom between $300 and $1,000 or restore their files from a backup. This is a widespread attack with a high distribution rate.
Emails either contain an attachment or a link to a website to open the notification, which then downloads the virus. Often, these emails slip through spam filters, as antivirus vendors are continually faced with variants of these malwares.
- Email users are cautioned to be on the lookout for suspicious emails (i.e., any unknown sender, UPS, faxing service, the FBI, etc.).
- NEVER open an attachment or click on a link within an email unless you are expecting the email and/or have confirmation that is it is safe to do so.
- Computer owners must ensure they have up-to-date firewall and anti-virus software running on their machines to attempt detection and deflect malicious software.
- Verify that you have a current backup of your systems.
The IC3 is a partnership between the Federal Bureau of Investigation (FBI), the National White Collar Crime Center (NW3C), and the Bureau of Justice Assistance (BJA). It recommends the public do the following:
- Carefully read emails you receive. Fraudulent messages often feature misspellings, poor grammar, and nonstandard English.
- Report emails you receive that purport to be from the FBI. Criminals often use the FBI’s name and seal to add legitimacy to their fraudulent schemes. In fact, the FBI does not send unsolicited emails to the public. Should you receive unsolicited messages that feature the FBI’s name, seal, or that reference a division or unit within the FBI or an individual employee, report it to the Internet Crime Complaint Center.
- Additionally, adjust the privacy settings on social networking sites you frequent to make it more difficult for people you know and do not know to post content to your page. Even a “friend” can unknowingly pass on multimedia that is actually malicious software.
- Do not agree to download software to view videos. These applications can infect your computer.
