URGENT MALWARE ALERT:
INCREASING CRYPTOLOCKER TRAFFIC

AppRiver is currently seeing a lot of malicious email traffic containing
the Cryptolocker malware that can encrypt your business's data. The
bulk of this traffic is coming through trusted free file share programs
disguised as voicemail messages or faxes. AppRiver is blocking all
known variants of this traffic but the spammers are changing up the
messages rapidly. It is incredibly important that you let your users
know not to open unsolicited emails and download files without
confirming their sources. It's also important that you back up your files
frequently and, if you use a third-party back up system, make sure it
will not overwrite your backup with the encrypted files.

As a reminder, Cryptolocker is an especially destructive virus that will
encrypt all of your data. Cyber criminals then force you to pay to get
the data back, with no assurance they will actually follow through if you
do. For more information, please see this blog article:
