5. What is ransomware and how does it work to encrypt files?

Ransomware is a type of malicious software (malware) that uses encryption to lock the user out of their own system or files. The attacker then demands a ransom payment, usually in cryptocurrency, in exchange for the release of the encryption key to unlock the files.

Ransomware typically spreads through phishing emails, malvertising, or through exploit kits that target vulnerabilities in software systems. Once executed on a computer system, it encrypts files by using a combination of symmetric and asymmetric encryption algorithms. This essentially scrambles the data so that it cannot be read without a decryption key.

The attacker will usually provide instructions on how to pay the ransom and receive the decryption key. However, there is no guarantee that paying the ransom will result in recovery of the encrypted files. In fact, paying the ransom only encourages attackers to continue using this method of attack and does not guarantee that they will release your files even if you pay. It is recommended to not pay the ransom and instead try other forms of data recovery such as restoring from backups or seeking assistance from security professionals.

6. How do denial of service (DoS) attacks disrupt networks and websites?

A denial of service (DoS) attack disrupts networks and websites by overwhelming the target system with an excessive amount of traffic, rendering it unreachable to legitimate users. This can be achieved in various ways, including:

1. Network flood attacks: An attacker floods the target network with a large volume of traffic, overloading its infrastructure and causing it to crash.

2. Application layer attacks: These attacks target vulnerabilities in applications or services running on the target system, causing them to crash or become unresponsive.
