 1. MALWARE ATTACK


A malware attack is a common cyber attack where malware (normally malicious software) executes unauthorised actions on the victim's system. Malicious software encompasses many specific types of attacks such as ransomware, command, spyware, control and etc.



"What is malware attack example?" this is perhaps the most widely known out of all IT security threats, since 1986, malware has become a significant concern for the enterprise users, with recent examples Solar winds Dark Halo breach and kaseya ransomware attack. 

  "What is malware attack and types?" there are different types of malware they are viruses, spyware, ransomware, adware, Trojan horses or any other kind of malware program that can get into the system. a program is called malware depending on the intention of the developer not on the actual features.

"Why does malware attack?" malware encompasses all types of malicious software,viruses and cyber criminals use it for many reasons,Tricking a victim into providing personal data for identify data.

 "What malware can do?" malware attacks can crack weak passwords, spread through networks, bore deep into systems and disrupt the daily operations of an organisation.Other types malware can look up important files, slow down your computer spam you with ads.

"What are malware threats?" malicious software is any program or file that is intentionally harmful to a computer, server or network. Types are worms, computer viruses, spyware,ransomware, Trojan horses.

 2. MAN-IN -THE-MIDDLE ATTACK

A man in the middle attack is a type of cyber attack in which the attacker secretly intercepts and relays messages between two parties who believe they are communicating directly with each other. Attack is a type of eavesdropping in which the attacker intercepts. Then controls the entire conversations.



"How does a man in the middle attack work?" this a a type of cyber attack in which an attacker eavesdrops on a conversation between two targets. Attacker may try to "listen" to a conversation between two people, two systems, persons and system.

"What causes a man in the middle attack" this attacks often occur due to TLS implementations/suboptimal SSL. That enables the SSL BEAST exploit or supporting the use of outdated and under secured ciphers. Imperial provides its customer with an optimized end to end TLS/SSL encryption, as part of its suite of security services.

"What type of attack is a man in the middle attack?" this attack is a type of eavesdropping attack, where attacker interrupt an existing conversation or data transfer. After inserting themselves in the "middle" of the transfer, attackers pretend to be both legitimate participants.

"How can man in the middle attacks be prevented?" VPNs can be used to create a secure environment for sensitive information within local area network. Use key based encryption to create a sub net for secure communication. This way, even if an attacker happens to get on a network that is shared, he will not be able to decipher traffic in the VPN.

"Where is a man in the middle attack possible?" the most susceptible for a this attack are the financial sites, other sites that require a login and any connection meant to be secured by a private or public key.

hacking tips and tricks


3. PHISHING


Phishing is a form of fraud in which an attacker masquerades as a reputable entity or person in email or other forms of communication. The attacker will commonly use phishing emails to distribute malicious links. The attachments that can perform a variety of function. 



"Why is it called phishing?" analogous to fishing, phishing is also a technique to "fish" for passwords,usernames and other sensitive information, from a "sea" of users.

"Is phishing a crime?" While phishing a covered under various state laws, there in no federal statute that directly criminalizes this type of activity. However, there are broader federal criminal laws that do apply to phishing and identity theft crimes.

"What do phishing  emails look like?" Phishing emails and text messages may look like they're from a company you know or trust. There from a bank, a credit card company, social networking site, an online payment website or app.

"How is phishing done?" In a phishing attack, bait often appears as a compelling email. Attackers go to great lengths to ensure that their emails appear as legitimate as possible. These emails commonly direct target recipients to an attacker controlled websites that delivers malware.The intercepts user credentials.

 

4. DENIAL-OF-SERVICE ATTACK

A Denial of service attack is an attack meant to shut down a machine or network, the making it inaccessible to its intended users. This attacks accomplish this by flooding the target with traffic, the sending it information that triggers a crash.




"Examples of denial of service attack?" Examples are Black Friday sales, when thousands of users are clamouring for bargain, often cause a denial of service. They can also be malicious. This case attacker purposefully theirs to exhaust the site's resources, a denying legitimate users access.

"Denial of service attack malware?" a type of cyber attack designed to disable, website or service or shut down or network. A malware is used to interrupt or inhibit the normal flow of data and a out of a system to render the target useless.

"Why would someone do a denial of service attack?" seeking their revenge. An extremely common reason for DDoS attacks, this situation could apply to businesses, a individuals, as well as


5. ZERO DAY EXPLOIT


If  a hacker manages to exploit the vulnerability before software developers can find a fix, that exploit becomes known as a zero day attack. Zero day vulnerability can take almost any form, because they can manifest as any type of broader software vulnerability.  




"What is a zero day vulnerability exploit ?" a zero day vulnerability is a vulnerability  in device and system that has been disclosed but is not patched. The exploit that attacks a zero day is called a zero day exploit.

"what is zero day exploit code?" a zero day vulnerability is an unknown security vulnerability or software flaw that a threat actor can target with malicious actor uses to leverage the vulnerability to attack a system.

"What is zero day ?" the term "zero day" originally referred to the number of days since a new piece of software was released to the public, so "zero day" software was obtained by hacking into a developer's computer before release.

"What is zero day vulnerability can it be prevented?" this is a software vulnerability that is discovered by attackers before  the vendor has become aware of it. No patch exists for zero day vulnerability and user systems have no defences in piece, making attacks highly likely to succeed.


6. SQL INJECTION

SQL injection is a technique that attackers use to gain unauthorized access to a web application database by adding a string of malicious code to a database query. A SQL injection manipulates SQL code to provide access to protected resources, such as sensitive data or execute malicious SQL statements.




"How SQL injection attacks occur?" If the web application fails to sanitize user input, an attackers can inject SQL of their choosing into the back end database and delete, copy or the modify the contains of the database. The attacker can also modify cookies to poison a web application's database query.

"Examples of SQL injection?" SQL injection is a code injection technique that might destroy your database. SQL injection is one of the most common web hacking techniques. The SQL injection is the placement of malicious code in SQL statements.

"Why would a hacker use SQL injection?" the data damage may be permanent. Motivations behind an SQL injection attack are often financial. Hacker might sell sensitive data on the dark web or group of malicious may with to give themselves an advantage by setting your business back. 

"How can SQL injection be prevented?" a common first step to preventing SQL injection attacks is validating user inputs, identify the essentials SQL statements, The establish a whitelist for all valid SQL statements, leaving invalidated statements out of the query. Process of this is known as input validation or query redesign.


7. DNS TUNNELING


DNS Tunneling is a method of cyber attack that encodes the data of other protocols in DNS queries, programs and responses tunneling often includes data payloads that can be added to an attacks DNS server and used to control a remote server and applications.

 



"How can be detected the DNS Tunneling?" this is a difficult to detect attack that routes DNS requests to the attacker's server, control channel, providing attackers a covert command and data ex filtration path. This is like a phone book for the internet, a helping to translate between IP addresses and domain names.

"Do hackers use DNS ?" this is name server is a highly sensitive infrastructure which requires strong security measures as it can be hijacked and used by hackers to mount DDos attacks on others attacker.

"What is DNS tunneling used for?" this is exploits the DNS protocol to tunnel malware and other data through a client server model. The attacker registers a domain, such as badsite.com. This name server points to the attacker's server, where a tunneling malware program is installed.

"What is DNS spoofing explain?" DNS spoofing is the process of poisoning entries on a DNS server to redirect a targeted user to a malicious website under attacker control.


8. ROOTKITS

Rootkit malware is a collection of software designed to give malicious actors control of a computer application or network. The malicious program sets up a backdoor exploit and may deliver additional malware, such as ransomware, Trojans, bots, key loggers.




"What do rootkits do?" the whole purpose of a rootkit is to protect malware think of it like an invisibility cloak for a malicious program. This malware is then used by cyber criminals to launch an attack. The malware protected by rootkit can Evan survive multiple reboots and just blends in with regular computer processes.

"What are rootkits attacks?" rootkit malware is a collection of software designed to give malicious actors control of a application and computer. The malicious programs sets up a backdoor exploit. They deliver additional malware, such as ransomware.

"Examples of rootkit?" Phishing, and social engineering attacks. They can enter computers when users open spam emails. The inadvertently download malicious software. The rootkits also use key loggers that capture user login the information.

"Can rootkits be removed?" a rootkit is a stealthy and dangerous type of malware that lets hackers access your computer without your knowledge. These nearly invisible bits of software can be found and removed. 


9. IOT ATTACKS

An its basic level, an attack is the total number of entry points for unauthorised system access. An IOT attack surface goes beyond entry points and includes all possible security vulnerability for IOT devices,software, and network connections.




"What is the type of IOT attack?" this device are vulnerable to hijacking and weaponize for use in distributed denial of service attacks, as well as targeted code injection, the man in the middle attacks and spoofing.

"What is IOT attack surface?" this attack is surface i the sum total of all potential security vulnerability in IOT devices and the associated software and infrastructure in a given network, be it local.

"How do IOT attacks work?" attacks can originate from the channels that connect IOT components with one another. Protocol of IOT systems can have security issues that can affect the entire systems.This systems are also susceptible to known attacks such as denial of service.

"What causes IOT attacks?" the number of unsecured devices connected to corporate networks increase, they do IOT ransomware attacks.Hackers infect devices with malware to turn them into botnets that probe access points or a search for valid credentials in device firmware that they can use to the enter network.


 10. XSS ATTACK

Attacks stores malicious script in the data sent from a website's search or contact from.A examples of reflated cross scripting is a search from, where visitors sends their search query to the server and only they see the result.




"What is XSS injection attack?" cross site scripting attacks are a type of injection, in which malicious scripts are injected into otherwise benign and trusted websites. This is occur when an attacker uses a web application to send malicious code, generally in the from of a browser side script to a different end user.

"What is XSS and how do you prevent it?" this is a client vulnerability that targets other application users, white SQL injection is a server side vulnerability that target the application's database. Filter your inputs with a whitelist of allowed characters and use type hints or type casting.

"What is XSS and CSRF?" cross site scripting allows an attacker to execute arbitrary JavaScript within the browser of a victim user. Cross site request forgery allows an attacker to induce a victim user to perform actions that they do not.
