What is a cyber-attack? — A cyber-attack is a strike against an organization’s computer network or an internet application. It is usually a malicious attempt to benefit from breaking into the systems, interrupting service, and stealing data. It is usually performed by an individual or group of black-hat hackers.
They use a variety of tools and practices to perform the attacks, these include exploit kits, Malware, Ransomware, SQL injections, etc.
Is not uncommon to see countless headlines about businesses losing money, compromising customer’s data and getting fined due to cyber-attacks.
It’s a fact, cyber-attacks occur every day. According to The 2017-2018 Global Application & Network Security Report by Radware, cyber-attacks are becoming more frequent and efficient. More than 62% of the surveyed businesses from different industries experienced daily attacks and 15% of those had complete outages.
Here is our list of the best cyber attack security monitoring software:

- RSA NetWitness Suite A cloud platform that offers a SIEM, and an extended detection and response system to identify and shut down malicious activity.
Reasons Why Hackers Attack
Hackers have multiple reasons to perform a cyber-attack on target vulnerable networks. One of the most common reasons hackers attack is to either steal or leak information. This can be data from real-life customers, internal employees, or sensitive business data. Hackers use this information to steal identities, credit cards, and bank accounts and finally steal money.
But not all hackers are after making a profit. Some of them attack for the pleasure and glory. The more services they interrupt, the more they prove themselves, the more reputation they gain. Others perform cyber-attacks just to prove their ideals and protest against different political or economical movements.
What is a Botnet?
Some skilled hackers are able to take down complete websites and business services. They stand behind while their army of bots to their job. A bot is a malicious software unintentionally downloaded to a computer. It allows hackers to gain full control of the computer and use it to distribute malware, phishing scams, distribute spam, send out spyware, etc.
When a hacker is able to accumulate a large number of these bots, the collection of these bot-infected computers becomes the botnet. An attacker (also called a bot herder) creates a botnet to increase the magnitude of the attack. A botnet is frequently used to shut down services with deadly DDoS (Distributed Denial of Service) attacks.
Common Types of Cyber-Attacks
The following section describes what are the most common types of cyber-attacks and how they work.
- Man in the Middle
- DoS and DDoS
- Cross Site Scripting
- SQL Injection
- Zero Day Exploits
1. Malware Used in Cyber Attacks
Malware “Malicious Software” is developed by a cyber-attacker with the purpose of invading the target’s computer and taking some or full control. Usually, Malware can infect the system or network with the initial unintentional and unknowing help from a human and continue to self-replicate automatically. Once security is breached and the Malware is in the system, it can do serious damage.
Hackers lure a user to click an email attachment, download an executable software hidden as an ebook, or infect portable devices so that they can spread faster.
Here are the Most common types of Malware of 2021:
- Virus Spreads with user action, such as opening an infected file. They depend on a host file.
- Worms They replicate themselves automatically, without the use of a host file.
- Trojan Horse Malware that disguises as legitimate software. Once you install the “legitimate software” the malware takes control of your system.
- RootKit Hidden deeply within the computer files. It provides continued privilege or backdoor access to the computer.
- Logic Bomb A set of instructions inserted into software that sets off a malicious action when a certain condition is triggered.
- Exploit Kit Searches for software vulnerabilities. It is very effective on unpatched systems.
- Adware Stands for Malicious Ads. It presents continuous unwanted ads on a computer. Some adware monitors the user’s behavior so it can serve tailored ads.
- Ransomware It blocks (kidnaps) key files or data on the computer and asks for money so they can be liberated.
A cyber-attack that aims to obtain sensitive information by cheating targets into believing fake messages. Phishing attackers disguise themselves as a trustworthy source and send lures usually through email, social media, or other electronic media.
Phishing relies on social engineering to be able to deceive its targets. It makes a user enter their personal information, such as username, password, credit card, etc to a fake website that looks like the legitimate site, but it is not. The fake website either keeps sensitive information or installs Malware on the user’s computer.
3. Man in the Middle Attack
As the name implies, an attacker sits in the middle of the communication between two targets and is able to eavesdrop. The Man-In-The-Middle Attack or MITM attempts to secretly intercept and listen to the legitimate communication between two hosts.
The attacker acts as a relay who listens and sometimes even alters the conversations with the two hosts. It intercepts the entire communication passing through the two victims and even inserts new messages.
A MITM can happen in any sort of online or electronic communication.
Here are the Most Common of MITM attacks:
- Email Hijacking
- Wireless LAN Eavesdrop
- Session Hijacking
4. DoS and DDoS Denial of Service Attack
This cyber-attack floods the systems with too much traffic that it overloads resources and bandwidth, making servers and network unavailable. With too much information a server or system is often unable to respond to valid requests so it overloads. DoS attackers attempt to make network resources unavailable to its legitimate users by flooding the servers with junk and oversized requests.
In a DDoS Distributed Denial of Service attack, the source of DoS traffic comes from multiple different places. An attacker usually crafts a DDoS with an army of bots (or botnet). All bots (also referred to as Zombies) in a botnet are infected systems that can be controlled to send loads of malformed traffic.
A variation of DDoS is the HTTP Flood. This attack controls the HTTP and POST unwanted requests to attack a web server. The HTTP Flood uses a botnet to overwhelm a server with too many HTTP requests.
5. Cross Site Scripting
This attack aims to insert malicious code into a website which targets a visitor’s browser. Cross Site Scripting, also knowns as XSS targets trusted web applications. The attacker uses the web app to inject the code such as a browser or client-side scripts that is viewed by other users of the same application.
This attack is performed by hackers to bypass and gain access to applications. An XSS works because some web applications use inputs from users found in the output generated without validation. The web browser of the victim doesn’t know that the script came from somewhere else. The web browser trusts the legitimate site, so it allows the third-party “malicious” script to access cookies, session tokens, and other sensitive information kept on the web browser.
6. SQL Injection
An SQL injection attack interferes with the queries that a web application makes to the database. An attacker inserts crafted SQL (Structured Query Language) code lines that allow data to be revealed. This data is retrieved from the database which could be information about other users. The attacker gains access because the database is unable to recognize the “incorrect statements” and filter out the illegal input values.
In some cases the SQL injection can also modify or remove data, harming the content of the databases and the application’s normal behavior. To perform an SQL injection is just a matter of submitting the malicious SQL statements into any vulnerable entry field such as a search box.
7. Zero-day Exploits
When new software is developed, it usually contains countless bugs and vulnerabilities. When software developers find their own vulnerability they quickly develop patches and updates. But sometimes this process is slow.
Black-hat hackers take advantage of zero-day exploits and are able to find vulnerabilities in new software much faster. They are able to target this vulnerability before users update their software.
Solutions for Monitoring Against Cyber Attacks
Social Engineering bypasses all technologies, including firewalls…
– Kevin Mitnick, World Famous Hacker & Security Consultant
When it comes to defending your network against cyber-attacks, the best tools are your own judgment, common sense, and a solid basic cyber-security training. It is believed that only about 3% of Malware is able to exploit a technical flaw. The remaining, 97% relies on tricking humans through social engineering to gain easier access into the network, [Source: KnowBe4].
Training personnel to avoid being tricked and scammed is one of the core elements for a strong cyber-security. But threats come from different directions and in different forms, that is hard to remain 100% defensive. Although you might be able to tackle that 97 % of social engineering threats, you still need to protect from the 3%, which is a lot.
Protecting from the whole spectrum of cyber-attacks is really challenging. Although Operating Systems come with their own security, it is usually not enough. Cyber-security tools and SIEMs (Security Information and Event Management) come in pretty handy when your network is medium to large.
