7 Most Common Type Of Cyber Attacks
A cyberattack is a malicious and willful effort by a person or company to breach the data system of another person or organization. Normally, the attacker expects some form of advantage from interrupting the victim’s network.
Cyber attacks hit companies daily. Former Cisco CEO John Chambers once said, “There are two kinds of businesses: those which were hacked, and people who don’t yet know they’ve been hacked.”
Cybercrime has increased annually as people attempt to gain from exposed small business systems. Cyber threats may also be launched together with ulterior motives. Some attackers seem to obliterate data and systems as a kind of” hacktivism.” Following are some of the most common types of cyberattacks:
1. SQL injection
A Structured Query Language (SQL) injection takes place when an attacker inserts malicious code into a host which uses SQL and forces the server to disclose the information it normally wouldn’t. An attacker could conduct a SQL shot by simply submitting malicious code into a vulnerable site search box.
2. DNS Tunneling
DNS tunneling uses the DNS protocol to convey non-DNS visitors over port 53. It transmits HTTP and other protocol traffic within DNS. There are many, legitimate reasons to use DNS tunneling. But, in addition, there are malicious motives to utilize DNS Tunneling VPN services. They may be employed to disguise traffic as DNS, hiding data that are typically shared via an online connection. In addition, it can be used for control and command callbacks in the attacker’s infrastructure into a compromised system.
3. Man-in-the-middle attack
Man-in-the-middle (MitM) attacks, also referred to as eavesdropping attacks, happen when attackers fit themselves into some two-party trade. When the attackers disrupt the traffic they could filter and steal information.
a. On unsecured Wi-Fi, attackers can add themselves between a customer’s device and the community. Without understanding, the visitor moves all information throughout the attacker.
b. When the malware has broken an apparatus, an attacker can set up applications to process all the victim’s data.
Malware is a phrase used to refer to malicious software, such as spyware, ransomware viruses, and viruses. Malware breaches a system by means of a vulnerability, normally every time a user clicks a harmful connection or email attachment which then supports insecure software. Once in the machine, malware can perform the following:
- Blocks access to crucial components of the system (ransomware)
- Installs malware or other harmful applications
- Covertly obtains data by transmitting data in the hard disk (spyware)
- Disrupts certain parts and leaves the system inoperable
5. Zero-day exploit
A zero-day exploit strikes after a community vulnerability is declared but before a patch or alternative is executed. Attackers target the revealed vulnerability in this window of time. Zero-day vulnerability hazard detection demands continuous consciousness.
6. Denial-of-service attack
A denial-of-service attack flooding systems, servers, or networks with visitors to exhaust bandwidth and resources. Because of this, the machine isn’t able to meet legitimate requests. Attackers may also use multiple endangered devices to establish this attack. This is referred to as a distributed-denial-of-service (DDoS) attack.
Phishing is the practice of sending deceptive communications that seem to come from a respectable source, typically through email. The target is to steal sensitive information such as credit cards along with login info or to install malware on the victim’s system. Phishing is an increasingly frequent cyberthreat.
