The owner can control the botnet using command and control software.

Unlike other kinds of viruses/malware, backdoor attack elements reach the core of the targeted application and often drive the aimed resource as a driver or key administrator. The impact of these actions could be highly detrimental. https://padlet.com/mehrnazhooshmand/5oyeeun3vxwi3zk4/wish/2398138842 2022-11-25 16:41:04 UTC https://padlet.com/mehrnazhooshmand/5oyeeun3vxwi3zk4/wish/2398138842 https://padlet.com/mehrnazhooshmand/5oyeeun3vxwi3zk4/wish/2398139026 2022-11-25 16:41:24 UTC https://padlet.com/mehrnazhooshmand/5oyeeun3vxwi3zk4/wish/2398139026 Man-In-The-Middle https://padlet.com/mehrnazhooshmand/5oyeeun3vxwi3zk4/wish/2398139865 A man in the middle (MITM) attack is a general term for when a perpetrator positions himself in a conversation between a user and an application—either to eavesdrop or to impersonate one of the parties, making it appear as if a normal exchange of information is underway.]]> 2022-11-25 16:42:56 UTC https://padlet.com/mehrnazhooshmand/5oyeeun3vxwi3zk4/wish/2398139865 https://padlet.com/mehrnazhooshmand/5oyeeun3vxwi3zk4/wish/2398140952 2022-11-25 16:44:44 UTC https://padlet.com/mehrnazhooshmand/5oyeeun3vxwi3zk4/wish/2398140952 adware https://padlet.com/mehrnazhooshmand/5oyeeun3vxwi3zk4/wish/2398142827 Adware:  The most visible malware.  Software that displays advertisements and collects data.There are two ways that users come across adware: downloading it by mistake or picking it up from a malicious website.Unlike other forms of malware, adware is commonly downloaded by the user with another programme. In fact, many people download it without even realising because they didn’t read the terms and conditions – so they tick a box and end up with the software they wanted and a new programme they have no interest in that’ll spam them with ads.

Spyware is a form of malware that hides on your device, monitors your activity, and steals sensitive information like bank details and passwords.Spyware can make its way onto a device without the end user's knowledge via an app install package, file attachment or malicious website. In its least damaging form, spyware exists as an application that starts up as soon as the device is turned on and continues to run in the background. Its presence will steal random access memory and processor power and could generate infinite pop-up ads, effectively slowing down the web browser until it becomes unusable.]]> 2022-11-25 16:48:13 UTC https://padlet.com/mehrnazhooshmand/5oyeeun3vxwi3zk4/wish/2398143051 rootkits https://padlet.com/mehrnazhooshmand/5oyeeun3vxwi3zk4/wish/2398143232 Rootkits:  A rootkit is a collection of computer software, typically malicious, designed to enable access to a computer or an area of its software that is not otherwise allowed (for example, to an unauthorized user) and often masks its existence or the existence of other software.Rootkit malware is a type of software that allows people to take control of a computer network or application. When launched, the computer virus creates a backdoor loophole and may deliver additional malware such as ransomware, bots, keyloggers, or trojans. Rootkits can remain undetected for years because they are difficult to detect, thanks in part to their ability to block some antivirus and malware scanner software.]]> 2022-11-25 16:48:33 UTC https://padlet.com/mehrnazhooshmand/5oyeeun3vxwi3zk4/wish/2398143232 Types of Man-In-The-Middle-Attack https://padlet.com/mehrnazhooshmand/5oyeeun3vxwi3zk4/wish/2398145209 There are total 7 types of Man-In-the-Middle attacks

  1. IP spoofing
  2. DNS spoofing
  3. HTTPS spoofing
  4. SSL Hijacking
  5. Email Hijacking
  6. Wi-Fi Eavesdropping

  1. Force HTTPS -HTTPS can be used to securely communicate over HTTP using a public-private key exchange. This prevents an attacker from having any use of the data he may be sniffing.
  2. Use end-to-end Encryption
  3. Only connect to secured Wi-Fi routers or use your wireless carrier’s encrypted connection.
  4. Be sure that your home Wi-Fi network is secure. Update all of the default usernames and passwords on your home router and all connected devices to strong, unique passwords.
  5. Be Aware of new things happening in cybersecurity.

A virus is malicious software attached to a document or file that supports macros to execute its code and spread from host to host. Once downloaded, the virus will lay dormant until the file is opened and in use. Viruses are designed to disrupt a system’s ability to operate. As a result, viruses can cause significant operational issues and data loss.]]> 2022-11-25 17:03:42 UTC https://padlet.com/mehrnazhooshmand/5oyeeun3vxwi3zk4/wish/2398152395 Worms https://padlet.com/mehrnazhooshmand/5oyeeun3vxwi3zk4/wish/2398152636 Worms are a malicious software that rapidly replicates and spreads to any device within the network. Unlike viruses, worms do not need host programs to disseminate. A worm infects a device via a downloaded file or a network connection before it multiplies and disperses at an exponential rate.
