Category: Ransomware
Ransomware is a type of malware from cryptovirology that threatens to publish the victim’s personal data or perpetually block access to it unless a ransom is paid. While some simple ransomware may lock the system so that it is not difficult for a knowledgeable person to reverse, more advanced malware uses a technique called cryptoviral extortion. It encrypts the victim’s files, making them inaccessible, and demands a ransom payment to decrypt them. In a properly implemented cryptoviral extortion attack, recovering the files without the decryption key is an intractable problem – and difficult to trace digital currencies such as paysafecard or Bitcoin and other cryptocurrencies that are used for the ransoms, making tracing and prosecuting the perpetrators difficult.
The Importance of a Firewall
Firewalls act as a first line of defense, separating internal networks from untrusted networks like the internet and filtering data packets to admit only legitimate applications, communication, and connectivity. A firewall uses pre-programmed rules to assess each data packet and determine whether to allow it, block it or record it
