Today, ransomware is a worldwide problem
First, let’s clarify what malware is. Malware is an umbrella term for any kind of malicious software.
Ransomware represents the most common type of malware. Over the last years, ransomware has become one of the biggest cyber scams to hit businesses.
We raise the awareness of Crypto-ransomware attacks
Crypto-ransomware is more destructive because it encrypts important files and data that you mostly need. After that, the encrypted files can only be restored to their normal state, using a specific decryption key. As such, many businesses have been forced to pay the ransom in exchange for a decryption key, which may not always work. In addition that ransom is usually paid in Bitcoin which is the preferred currency by the attackers. Usually, Crypto -ransomware does not target critical operating system files, allowing you (the user) to still use the computer and purchase bitcoins to pay the ransom.
"Bitcoin is an electronic currency that is much harder to trace and thus helped anonymize the transactions"
"Be aware, criminals know they can charge businesses a much higher ransom than individuals"
Example of a typical ransomware message
The malware blocks access to documents, spreadsheets, photos, videos, and other important files from your system like .doc,.xls,.mp3, etc. Once the files are encrypted, the information will become indecipherable and inaccessible. After that, the user will receive a pop-up notification demanding payment of a ransom in exchange for the decryption key.
A successful ransom attack can disrupt businesses on a larger scale. Therefore, organizations can suffer lost productivity, loss of business and potentially the permanent loss of data.
