You may
recently have heard of a new variant in ransomware, “The Encrypto Virus”. This
is a particularly nasty piece of malware that, in addition to locking your
computer, sets a time limit on “unlocking” it, and threatens to destroy all
your information if you don’t pay. Once your computer has been infected the
message displayed on the screen warns that your files have all been encrypted
and if you don’t send a payment within a certain time frame, all your
information will be lost forever—no one will ever be able to unlock your files
without the hacker’s “key” to decryption.
How does the
Encrypto virus spread? Typically, through email, the hackers hide the Encrypto
virus in an attachment that looks like a PDF but is actually an executable, or
.exe file. If you or someone on your staff opens the phony PDF, the virus
encrypts the files on your computer and tells you that you can only get the key
to unlock them if you pay.
It’s a scary
possibility. An attorney in Oklahoma made the news recently when he went public
about his law firm being attacked by the Encrypto virus, and his plans to pay
the ransom.
So, what can
you do to protect yourself and your small business network against the Encrypto
virus and other types of malware that attack by encrypting your files?
First, we know
you’ve heard this often but it’s well worth repeating—always be vigilantly
careful about opening attachments to email! The fake PDFs containing the
Encrypto virus will seem to come from a trusted source, like Xerox delivering a
scanned image, or FedEx sending package tracking information. If you or your
staff EVER receive emails with attachments, make sure you are actually
expecting that email and its attached information from that particular source
before opening the attachments. It’s easy to forget during a hectic work day,
especially when you have an intimidating backlog of email to get through, but
it’s vital to preventing these kinds of computer viruses from infecting your
system.
If you’re using
Windows, disabling hidden file extensions can help detect these attacks before
your computer is infected.
If your
computer does get infected by this type of encryption virus, manually
disconnect it from your wireless or wired connection immediately in order to
prevent it from spreading to other computers on your network.
Another
reminder that almost can’t be repeated enough—make sure you have a separate
backup system for all your most important files. If you lack such a system or
just want some advice about your best options, Full Sky specializes in network
services. We also offer consultation and planning for the best network
security. Call or email us with any questions info@fullskytech.com or 513 206 9971
