What is a cyberattack?
What are the different types of cyberattacks and threats?
Cyberattacks come in various forms through computer networks and systems. Malware and phishing are two cyberattack examples used to gain control of sensitive data from businesses and personal electronic devices. Learn about the types of cyberattacks and their effect on recent technology.
-
Malware
Malware, or malicious software, disguises itself as a trusted email attachment or program (i.e., encrypted document or file folder) to exploit viruses and allow hackers into a computer network. This type of cyberattack often disrupts an entire IT network. Some examples of malware are trojans, spyware, worms, viruses, and adware.
-
Distributed Denial-of-Service (DDoS) attack
A DDoS attack is when several hacked computer systems target a site or network and deny the user experience on that specific website or network. For example, hundreds of pop-ups, advertisements, and even a crashing site can contribute to a DDoS attack on a compromised server.
-
Phishing
Phishing is the act of sending fraudulent emails on behalf of reputable companies. Hackers use phishing to gain access to data on a personal or business’ network.
-
SQL injection attacks
An SQL injection attack is when a cybercriminal exploits software by taking advantage of apps (i.e., LinkedIn, Target) to steal, delete, or gain control of data.
-
Cross-site scripting (XSS)
Cross-site scripting (XSS) is when a cybercriminal sends a “script-injected” or spammed website link to your inbox, and it’s opened—releasing personal information to said criminal.
-
Botnets
Botnets are when multiple computers, normally on a private network, are infected with viruses and other forms of malicious software, I.e., pop-up messages or spam.
-
Ransomware
Ransomware is a type of malicious software, or malware, that threatens a victim by destroying or blocking access to critical data or systems until a ransom is paid.
-
United States Office of Personnel Management
Noted as “one of the most significant data breaches in US history,” the US Office of Personnel Management was hacked in April 2015 costing 21.5M investigations, 19.7M applicants that applied for an investigation, and 5.6M fingerprints to be stolen.
-
Equifax
In 2017, Equifax failed to correct network vulnerability by properly securing their data. This led to over 147.9M customers in the United States, UK, and Canada getting their credit card details and social security numbers stolen by hackers.
-
Russian cyberattacks
Within the past year, over 58% of all cyberattacks observed by Microsoft have been attributed to hackers in Russia. Their hackers have been effective in stealing data from other countries with a 32% success rate in 2021.
-
CNA Financial
Insurance company CNA Financial was hit with a ransomware attack in March 2021, leaving employees locked out of internal systems and resources. The cyber hackers also stole valuable data, reportedly resulting in a USD$40 million settlement paid by CNA Financial.
-
Colonial Pipeline
When the Colonial Pipeline Company was hacked on May 7, 2021, all operations were shut down to contain the attack. In order to restore the computerized system used to manage oil pipelines throughout the southeastern United States, Colonial Pipeline paid the hackers a ransom of 75 bitcoins (equivalent to USD$4.4 million at the time). This cyberattack was the largest in U.S. history to target oil infrastructure.
-
Cryptocurrency
In March and April 2022, three different lending protocols came under cyberattack. In the span of one week, hackers stole USD$15.6 million worth of cryptocurrency from Inverse Finance, USD$625 million from gaming-focused Ronin Network, and USD$3.6 million from Ola Finance.

Cyberattack mitigation is when companies develop strategies to prevent incidents, like cyberattacks, that limits the amount of damage done if a threat is posed.
Threat protection can fall under three components to enforce cyberattack mitigation: prevention, identification, and remediation.
Prevention: businesses place policies and procedures in order to eliminate the possibility of a threat hosted by outside organizations or individuals.
Identification: security software and management allow businesses to manage less and innovate more without the worry of internal data breaches.
Remediation: utilizing business software like Zero Trust, and strategies to contain active security threats that have breached internal networks and systems.
Cyberattack remediation is how businesses deal with cyberattacks – their processes, strategies, and how they handle active threats moving forward.
Cyberattacks are unauthorized attempts to exploit, steal, and damage confidential information by taking advantage of vulnerable computer systems. The motivation behind cyberattacks can be political, criminal, and/or personal.
Cyber threats are individuals or businesses that can have internal or external access into a company’s network, and willingly abuse these processes. Examples could include cyberterrorist organizations, former employees, or an industry competitor.
Cyber risks are networks who are deemed most “at risk” for cyberattacks. Cyber risks are analyzed by FBI cyberattack data and data from the National Governors Association for state elections to determine what organization needs additional cybersecurity, and how much businesses are spending on cybersecurity and protection.
Cyberattacks occur whenever cyberterrorists try to gain access to a business or personal network for informational purposes. The motivation can be criminal, political, and/or personal. These individuals or organizations usually find holes within the company’s IT processes and take advantage of these vulnerable systems.
