Keep reading to learn everything about cyberattacks, and how you can prevent, detect, and respond to threats to your company. 

So, let’s get into the article!

What is a Cyberattack?

A cyberattack is any deliberate attempt to access, disrupt, or damage computer systems, networks, or data without authorization. Carried out by individuals, groups, or even state-sponsored entities, cyberattacks can take various forms, including malware infections, phishing scams, or direct hacking. 

Why Do Cyberattacks Happen? 

Cyberattacks happen for various reasons, driven by the motivations of the attackers involved in them. The primary categories of such motivation are criminal, political, and personal which drive these illegal activities. Criminally motivated attackers aim to gain financial benefits through activities like monetary theft, data theft, or disrupting business operations. Extortion is a very common tactic used by cybercriminals, who may hold data or devices hostage until a ransom is paid.

Personally motivated attackers, such as disgruntled employees, seek revenge for perceived dissatisfaction. They may steal data or disrupt systems to cause harm to their targets. Political motivations often involve cyberwarfare, cyberterrorism, or hacktivism. Nation-state actors target government agencies or critical infrastructure in cyberwarfare, while hacktivists use attacks to raise awareness for their causes.

Other motivations for cyberattacks include corporate espionage, where intellectual property is stolen for competitive advantage. Vigilante hacking is another motivation where vulnerabilities are exploited to warn others. Some attackers may also engage in hacking for the challenge or thrill it provides.

Who is Behind Cyberattacks?

Cyber attacks can be initiated by various entities, including criminal organizations, state actors, and private individuals. Threat actors can be categorized as outsider threats or insider threats.

Outsider threats involve organized criminal groups, professional hackers, state-sponsored actors, amateur hackers, and hacktivists. These entities gain unauthorized access to networks or devices to carry out malicious activities.

On the other hand, insider threats involve users with legitimate access to a company’s assets who misuse their privileges intentionally or accidentally. This category includes employees, business partners, clients, contractors, and suppliers with system access.

Recent warnings from cybersecurity agencies highlight the activities of Chinese state-sponsored hackers targeting critical infrastructure in the United States. Groups like Volt Typhoon, also known as Vanguard Panda and BRONZE SILHOUETTE, have breached IT environments in sectors such as communications, energy, transportation systems, and water and wastewater systems.

Politically motivated cyber attacks are also prevalent, with various countries being identified as sources of such attacks. China, Russia, Iran, and North Korea are among the countries associated with politically motivated cyber incidents in the world currently.

What do Cyberattacks Target?

Cyber attacks target various resources, both physical and logical, that possess vulnerabilities exploitable by threat actors. These attacks aim to compromise the confidentiality, integrity, or availability of the targeted resource.

Targets of cyber attacks may extend beyond the initially identified vulnerable resource, including the organization’s Wi-Fi networks, social media platforms, operating systems, and sensitive information such as credit card or bank account numbers.

The SolarWinds supply chain attack is a notable example of a cyber attack deployed for surveillance. Russian cybercriminals used malware in a SolarWinds product update to gain access to various US Government entities, intercepting private internal correspondences.

These sophisticated cyber attacks can evade traditional security measures like firewalls and VPNs by masquerading as legitimate computer processes, making it challenging for law enforcement to trace the perpetrators.

Common targets of cyber attacks include financial data, client lists, customer data (including personally identifiable information), email addresses, login credentials, and intellectual property such as trade secrets or product designs. Some cyber attackers may seek to disrupt information systems or IT infrastructure without the intention of stealing anything.

What Effects Do Cyberattacks Have on Businesses?

Cyberattacks can have devastating effects on businesses, impacting them financially, operationally, and in terms of reputation. Here’s an elaborate view of how cyberattacks can affect businesses:

Increased Costs

Businesses may incur significant financial losses due to cyberattacks. These costs include expenses related to cybersecurity technology, notifying affected parties, insurance premiums, public relations support, and ransom payments in the case of ransomware attacks. Legal costs may also arise from compliance efforts and civil cases resulting from data breaches.

Operational Disruption

Cyberattacks can disrupt normal business operations, leading to lost revenue and productivity. Attackers may use malware to erase valuable information or block access to essential systems, causing significant interruptions to business activities. Such disruptions can result in reputational damage and fade away customer trust.

Altered Business Practices

Companies may need to reassess their data collection and storage practices to enhance security measures. Some businesses may opt to cease online operations altogether due to security concerns, while others may face increased scrutiny from customers regarding their security protocols.

Reputational Damage

Cyberattacks can tarnish a company’s reputation, leading to decreased customer trust and loyalty. Customers may be hesitant to share sensitive information with a company that has experienced a data breach, resulting in lost sales and revenue. Suppliers, partners, and investors may also lose confidence in the affected business, further damaging its reputation.

Lost Revenue

A significant consequence of cyberattacks is the potential loss of revenue as customers seek out more secure alternatives. Businesses may also suffer financial losses due to extortion attempts by hackers or legal settlements resulting from data breaches.

Additionally, businesses may incur costs associated with repairing damaged systems and implementing enhanced security measures.

Stolen Intellectual Property

Cyberattacks can result in the theft of valuable intellectual property, including product designs, technologies, and go-to-market strategies. This stolen information can be used by competitors, resulting in lost market share and competitive advantage for the affected business.
