Ransomware
- What is it? (Updated)
Ransomware is a type of malware
that prevents a computer user from using their computer or from accessing the data stored on their computer. To regain access to their data, the user is
forced to pay a ransom for a decryption key. The ransom fee is typically demanded
in electronic currency or bitcoins.The ransomware infection can usually be
removed without paying up, by using a decent anti-virus program or
malware removal program. However, regaining access to your data is not so simple.
Locky is a
ransomware program that was recently released. This ransomware will encrypt
certain files using a mixture of RSA & AES encryption. When it has finished
encrypting your files, it will display a payment demand screen that prompts you
to send a bitcoin payment to an untracable internet address. You will be given
a time frame of a week to make the payment, else the payment amount will
increase.
This infection is typically
spread through emails which appear to be from people that you know. These
emails will contain a zip attachment that when opened would infect the
computer. The attachments are sometimes disguised as a PDF file. Since
Microsoft does not show extensions by default, they look like normal PDF files
and people open them.
Please be aware that currently,
there is no tool to that will successfully decrypt the encrypted files.
Bitdefender, an anti-malware and
virus protection company, recently released a crypto-ransomware utility that
will protect against the CBT-Locker, Locky and TeslaCrypt ransomware
infections. Click on this link; http://download.bitdefender.com/am/cw/BDAntiRansomwareSetup.exe
to download the utility. After downloading, install the program on your Windows
computer.
A good backup program, preferably
via redundant methods, including a cloud backup is the preferred solution.
After removal of the ransomware program, a restoration of your backup data
files will result in a minimal amount of down time. This latest round of
malware attacks shows how important having a good,reliable backup is.
