Beware of CryptoWall
July 31, 2014
The CryptoWall ransomware virus infiltrates users’ operating systems. After successful infiltration, this malicious program encrypts files stored on users’ computers and demands payment to decrypt them.
The majority of this traffic is coming through trusted free file share programs masked as voicemail messages or faxes. Our IT security experts are successfully blocking many of the known variants of Cryptolocker but spammers are continuously changing up the messages. It is crucial that you let your colleagues know not to open emails and download files without confirming their sources.
It’s also important that you backup your data frequently and, if you use a third-party backup system, make sure it will not overwrite your good backups with the encrypted versions.
Clients on our managed services program are covered. Our team is continually taking steps to limit any exposure to threats facing your computer network. Our email security, backups and antivirus services are monitored and updated regularly to make sure that your IT security solutions are doing their job.
For clients or organizations currently not engaged with us or without a current managed services agreement, we can help set up a complete end-to-end security solution. This will make sure your business is protected.
