The Most Common Types of Cyber Attacks

Digital crime by an anonymous hacker

Cyber-attacks are calculated and malicious attempts by hackers to damage or destroy a computer network or system. Hackers are constantly trying to get access to your network and information. For hackers, knowledge is power – power over you and your business. Luckily, knowledge is on your side as well. We’ve compiled a list of the most common types of cyber-attacks to keep you informed, aware, and proactive regarding the safety of your business.

Most Common Types of Cyber-Attacks



Malware refers to malicious software that breaches through vulnerabilities. This software includes spyware, ransomware, worms and viruses.

Your system can become compromised through opening a dangerous link, clicking around in an infected email, or downloading risky software.

How malware will negatively impact your network depends on its design. Ransomware will block access to key components of the network. Spyware covertly obtains information by transmitting data from the hard drive. Viruses and worms will disrupt certain components and render the system inoperable.


The goal of phishing is to steal sensitive data, like credit card or login information, or to install malware to the victim’s machine and network. A common way of gaining access to the machine is by untrustworthy emails. These emails can seem like they are coming from major corporations such as Google or Microsoft, or friends and family members, all with the goal to capture your information.

 Zero-Day Exploit

A zero-day exploit hits the same day a network vulnerability is announced, before a patch or solution is implemented. Threat detection during announcement and patch process requires constant awareness.

Man-in-the-middle attack

Man-in-the-middle attacks, aka eavesdropping attacks, occurs when attackers insert themselves into a two-part transaction. Once they drop in, the attackers filter through and steal your data.

There are two common entry points you should know about, too – unsecured public Wi-Fi and malware. Unsecured public Wi-Fi – attackers can see your activity on public Wi-Fi, and will exploit these findings to gain access to your system. The ever-dangerous Malware comes back to aid in these kinds of attacks. Once malware gets into your system, an attacker can install eavesdroppers to gather information.

Structured Query Language Injection

Structured Query Language (SQL) Injection is when an attack inserts malicious code into a server that uses SQL. This forces the server to reveal info it normally wouldn’t, such as intellectual property, personal information of customers, administrative credentials, or private business details.

The prime target for hackers is any application that uses a SQL database, with websites and vulnerable website search boxes being the most common prey.

Denial-of-Service attack

Denial-of-service (DoS) Attacks flood systems, servers, or networks with traffic to exhaust resources and bandwidth. Due to this exhaustion, the system will be unable to fulfill legitimate requests.

Attacks can come at any time, impacting any part of a website’s operations and resources, and can lead to massive amounts of service interruptions. When multiple compromised devices are used, it becomes a distributed-denial-of-service attack, or DDoS.

Having a DDoS mitigation plan in place can help circumvent any damages. The two largest DDoS attacks ever recorded were in March of 2018, with the worst having 1.7 terabytes served per second to the company servers. Thankfully, no damage or outages were reported from the attack with the mitigation plan in place.


Be proactive in your efforts to protect your business from cyber-attacks. Keep all systems and firewalls are up to date, and have a secured Wi-Fi connection. Employee training on identifying possible attacks will further help decrease the risk of an infection compromising your company. DataGroup Technologies adds an extra layer of defense.
