7 Types of Cyber Security Threats

Cyber Security Threats

Professionals in cyber security threats are constantly defending computer systems against many forms of cyber threats. Every day, cyber-attacks target corporations and private systems, and the diversity of attacks has grown rapidly. According to former Cisco CEO John Chambers, “there are two kinds of companies: those that have been hacked and those who don’t yet realize they have been hacked.”

There are numerous reasons for cyber-attacks. The first is money. Cyber attackers may take a system offline and demand cash to reactivate it. Ransomware, a type of assault that demands money to restore services, is more sophisticated than ever.

Individuals are also targets of cyber-attacks, often because they keep sensitive information on their mobile phones and use insecure public networks.

What Exactly Is a Cybersecurity Threat?

A cyber security threat is any potentially hostile attack that attempts to gain unauthorized access to data, disrupt digital activities, or damage information. Corporate spies, hacktivists, terrorist groups, hostile nation-states, criminal organizations, lone hackers, and disgruntled workers are all possible sources of cyber dangers.

Several high-profile cyber-attacks in recent years have resulted in the exposure of critical data. For example, the Equifax data breach in 2017 exposed the personal information of over 143 million people, including birth dates, addresses, and Social Security numbers.

In 2018, Marriott International announced that hackers gained access to its servers and stole the personal information of around 500 million clients.

The failure of the organization to develop, test, and retest technical measures like as encryption, authentication, and firewalls enabled the cyber security danger in both cases. Nextdoorsec.com is offering the best cyber security and penetration testing services in Antwerp, Belgium.

7 Different Types of Cyber Security Threats

Cyber security experts should be well-versed in the following sorts of cyber security threats.

1. Viruses

Malware is defined as malicious software, which includes spyware, ransomware, viruses, and worms. Malware is activated when a user clicks on a malicious link or attachment, which causes dangerous software to be installed. According to Cisco, once triggered, malware can:

2. Access to critical network components is restricted (ransomware)

Disrupt individual components, rendering the system unusable.

Emote is described by the Cybersecurity and Infrastructure Security Agency (CISA) as “an advanced, modular banking Trojan that primarily serves as a downloader or dropper of other banking Trojans.” Emote remains among the most expensive and damaging malware.”

3. Service Denial

A denial of service (DoS) assault is a sort of cyber attack that overloads a computer or network, rendering it unable to respond to requests. A distributed denial of service (DDoS) assault does the same effect, but the attack begins on a computer network. A flood attack is frequently used by cyber attackers to interrupt the “handshake” procedure and carry out a DoS. Several different ways may be utilised, and some cyber attackers may use the time that a network is down to launch other attacks.

According to Jeff Melnick of Netwrix, an information technology security software business, a botnet is a sort of DDoS in which millions of devices can be infected with malware and controlled by a hacker. Botnets, also known as zombie systems, target and overpower a target’s processing capabilities. Botnets are dispersed around the globe and difficult to track down.

4. Man in the Center

When hackers inject themselves into a two-party transaction, this is known as a man-in-the-middle (MITM) assault. According to Cisco, after disrupting traffic, they can filter and take data. MITM attacks are common when a visitor connects to an unsecured public Wi-Fi network. Attackers place themselves between the visitor and the network, then use malware to install software and steal data.

5. Scamming

Phishing attacks use forged communication, such as an email, to deceive the recipient into opening it and following the instructions contained within, such as submitting a credit card number. According to Cisco, the purpose is to “steal sensitive data such as credit card and login information or to implant malware on the victim’s machine.”

6. SQL Injection is a type of SQL injection.

A Structured Query Language (SQL) injection is a form of cyber attack that occurs when malicious code is inserted into a SQL server. When a server is infected, it releases data. Entering the malicious code into a susceptible website search box might be as simple as that.

7. Password Cracking

A cyber attacker can gain access to a variety of information with the appropriate password. Data Insider defines social engineering as “a tactic cyber attackers utilize that depends primarily on human interaction and frequently entails luring people into breaching basic security practices.” Accessing a password database or guessing a password are two further sorts of password attacks.
