Dear Bros. and Sisters in Christ,
Please read it
carefully.
Beware of “zepto” a “ cryptowall ransomware using RSA
encryption algorithm”.
What do we need to
know about it?
Ransomware is a fairly new type of virus that is very
different from any other type. Their agenda is quite different and
unique. The hacker will encrypt the files (rename all files with .zepto
extension, the original files will keep hidden or may deleted.) and then they
will require a payment through bitcoins in exchange with decryption code.
Bitcoins are a cyber-currency that are very difficult to be traced to the
receiver. This leaves the hacker in full anonymity.
The Zepto ransomware is distributed via spam email
containing infected attachments or links to malicious websites. Cyber-criminals
spam out an email, with forged header information, tricking you into believing
that it is from a shipping company like DHL or FedEx etc. The email tells you
that they tried to deliver a package to you, but failed for some reason.
Sometimes the emails claim to be notifications of a shipment you have made.
Either way, you can’t resist being curious as to what the email is referring to
– and open the attached file (or click on a link embedded inside the email).
And with that, your computer is infected with the Zepto ransomware.
What do we need to do
to protect our files?
- We should be extremely careful when handling emails with file attachments. a single click is enough to activate the malware and encrypt the victim’s files with the .zepto encryption.
- Be careful when opening new e-mails from unknown senders. If the letter seems suspicious, do not open it! Spam e-mails are one of the most common methods for ransomware distribution.
- Be careful, to open files with extension: .js , .wsf, .zip and .docm .
- Always have a back-up of your files to external drive, cloud, NAS or server.
- Install strong anti-malware and anti-virus software. For users of genuine Microsoft OS, download Microsoft security essentials for free.
- Avoid shady sites.
