we will discover about 7 top most common type of cyber attack in this vlog. As in hyperconnected world of today, cyberattacks have grown to be a major risk to people, companies, and even governments. Ransomware, phishing, and fileless malware are just a few of the more clever and sophisticated tactics that attackers are employing to steal confidential information, lock users out of their systems, or bring down entire websites. Given our increased reliance on technology, it is imperative that we comprehend how these cyberthreats operate. The most prevalent kinds of cyberattacks and their effects on the digital environment are what we will discuss.

What is a Cyberattack ?

A cyberattack is an action intended to damage or take advantage of a network, as well as to change, delete, or steal data from a computer or any part of a computerized information system. Cyberattacks have increased with the growing popularity of commercial digitization in recent years. Phishing, ransomware, denial-of-service (DoS), and malware infestations are just a few of the various ways these attacks can manifest. Cybercriminals frequently target private information, financial records, and intellectual property, which can result in monetary loss, harm to one’s reputation, and legal repercussions.

1. Ransomware

Ransomware holds the victim’s machine hostage until the victim agrees to pay the attacker a ransom. Following the payment, the attacker gives the target instructions on how to take back control of their computer. The malware demands a ransom from the victim, hence the fitting moniker, “ransomware.” This attack occurs when the target downloads the malware, either from an email attachment or from a website. Both the IT staff and the system’s manufacturer have failed to fix the flaws that the malware is designed to take advantage of. After that, the ransomware encrypts the target’s computer.

2. DoS and DDoS attack

In a denial-of-service (DoS) attack, a system’s resources are overloaded to the point that it cannot respond to valid service requests. A distributed denial-of-service (DDoS) attack is comparable in that it aims to exhaust a system’s resources. Numerous host computers under the attacker’s control that are infected with malware start a DDoS attack. A DoS attack floods the target website with requests that aren’t authorized. Since the website must reply to every request, all of the responses take up its resources. This frequently leads to the site being shut down entirely and prevents the site from serving users as it normally would.

3. Malware

Software created with harmful intention is known as malicious software, or malware. Malware comes in a wide variety, each intended to accomplish a certain task. Malware can display harmful advertisements, gather and steal trade secrets, or harm compromised computers, for instance. These are some typical forms of malware: Cybercriminals: these malicious programs mine digital currencies on the victim’s computer. Through a variety of techniques, including malicious software, SMS exploitation, and social media network usage, mobile malware attacks mobile devices. Malware known as “botnet malware” attacks a machine in order to integrate it into a network of bots. The system can then be used as part of the botnet by a botnet controller to carry out other illegal actions and cyberattacks.

4. Phishing

Phishing attacks attempt to fool end users into downloading malware or disclosing personal information. Phishing attacks use emails or texts that pose as trustworthy organizations, such as banks, or as reputable brands, such as eCommerce websites, a fraudulent website may pose as a trustworthy company and request personal and/or financial information from the user. The malicious website could even pose as a trustworthy company and encourage the user to fill out a form with private or financial information. Stressful calls to action, such as requesting that the victim confirm their credit card number or change their password immediately, may be included in the email itself.

5. Fileless Attack

By looking through the device’s files for known indications of dangerous information, antivirus software can identify malware. Through the use of commands to computer processes, fileless malware gets around this system. Consequently, this virus can accomplish its goal without being identified by conventional methods that depend on file inspection.

6. Accounts Takeover

Account takeover (ATO) is the process by which a threat actor takes control of an online account using credentials that have been stolen. Data breaches, fraud, or identity theft could result from it. Credentials can be obtained by threat actors through a variety of attacks, including phishing schemes, social engineering, and data breaches, or by buying them on the dark web. Threat actors can also utilize bots that automatically try to access the websites, logging in with various username and password combinations until they find a list of validated credentials.

7. MitM Attacks

Man-in-the-Middle (MitM) attacks give threat actors the ability to intercept data as it moves between two entities, such as networks, computers, or end users. The threat actor stands in the middle of the parties that are trying to communicate. MitM attacks essentially allow the threat actor to eavesdrop on the conversation while the two parties are unaware that someone else is listening or even altering the message before it even gets to its intended recipient.

Conclusion

Malware, phishing, ransomware, denial-of-service attacks, and other types of cyberattacks are all intended to compromise systems, steal information, or interfere with daily operations. The sophistication of these dangers increases with the rise in digital dependency. The strategies used by hackers are always changing, whether they are stealing login credentials or taking over entire networks. In today’s threat scenario, strengthening cybersecurity measures, remaining informed, and adopting safe online practices are crucial actions for people and businesses to secure their data and digital presence.
