Regulatory requirements now mandate that companies move even quicker and more thoroughly in the aftermath of an incident. Companies are hard-pressed to find a solution that can help them respond quickly, efficiently, and with confidence, especially in the cloud.

What are Cybersecurity Threats?

Cyber Security Startups create defences for cybersecurity threats which refers to risk or danger to one’s information security. It is a malicious attack or infiltration by an individual, company, or organization in order to access confidential information from another’s network. These attacks and breaches can also destroy computer systems and disrupt digital functioning. Cyber threats include data breaches, viruses, trojans, Denial of Service (DoS) attacks, and much more. 

Cyber security threats uk biggest cybersecurity threats uk

Sources of Cybersecurity Threats

Cyber threats come from a variety of sources or threat/malicious actors. It is important to locate them in order to take action against them or protect your data against them.

  • Nation-states: While most cyberattacks are mere nuisances, most of the serious cybersecurity threats are posed by hostile nation-states. Cyberattacks have become the most common modern warfare technique. From basic espionage, propaganda, website defacement, to disruption, learning national secrets, and even loss of life are all a part of cyber warfare. These attacks threaten national security and have the potential to disrupt critical infrastructures like electricity grids and gas control valves.
  • Organized crime groups: Organized crime groups or corporate spies pose a high risk to organizations by partaking in industrial espionage. Stealing trade secrets, money, disrupting profit-making mechanisms, and gaining access to blackmail material are some of the attacks by these threat actors.
  • Terrorists: In addition to hostile nation-states, another threat to national security comes from terrorist groups mounting attacks in cyberspace. Terrorists might have less cyber resources to threaten cybersecurity, but they continue to pose an increasing risk as more competent people join the ranks of terrorists.
  • Aggrieved insiders: A common source of cyberattacks is from inside the company or the organization. It’s easy for a  disgruntled insider to expose confidential data because they might already have access to them. Third-party vendors or employees who accidentally introduce malware are also examples of insider threat. This is more common in workplaces with the bring your own device (BYOD) policy. Organizations often fail to measure the corporate cybersecurity risks associated with it.
  • Hackers and Hacktivists: Hackers are intruders who gain illegitimate access to information systems by exploiting zero-day vulnerabilities. They might do this on a whim, to fulfil a challenge, or to simply brag. Earlier, hacking was a complicated task but today with automated scripts and protocols, it is much more sophisticated and simple. Hacktivists are a breed of hackers who are concerned with spreading propaganda. They intend to support their own political agenda and ideals.

Types of Threats Cyber Security Startups deal with

There are many types of cyber threats prevalent today, which are only increasing and becoming more sophisticated with time. The serious lack of cybersecurity professionals makes these threats even more challenging and uncontrollable. The Information Security Forum has warned against increased potential for disruption, deterioration, and distortion. Here are some of the most common cybersecurity threat examples:

1. Phishing

A cyberattack via emails that tricks the recipient into clicking a link containing malware. This malware then gets downloaded into the recipient’s computer and exposes confidential information and sensitive data. With increased awareness about phishing attacks, as employees become more vigilant for unknown links, cybercriminals have also upgraded to automated messages. These convincing messages trick unwitting recipients into compromising their user logins, credit card information, financial information, and private databases.

2. Ransomware

This refers to encrypting an individual or organization’s data and demanding a ransom for allowing the user to access it again. These attacks range from mere nuisances to serious incidents. Ransomware damages are expected to cost billions this year. Cybercriminals deploy technologies that enable them to hijack an individual or organization’s databases and hold all of it for ransom. With the rise in cryptocurrencies, attackers’ ransom demands can now be met anonymously, thus making these attacks easier and more widespread.

3. IoT Attacks  

The Internet of Things has become omnipresent. According to, the number of IoT devices is expected to reach 75 billion by 2025. These devices include home security systems, webcams, routers, medical devices, smartwatches, household appliances, etc. More IoT devices imply increased vulnerability to cyber threats. Hackers take over the device to make it a part of DDoS attack and gain unauthorized access to the data. DDoS or Distributed Denial of Service attack refers to a type of cyber threat wherein the attacker takes over many devices and uses them to overload networks.

4. Electronic Medical Records (EMRs)

With the field of healthcare getting digitized, from smart medical equipment to online patient databases, it is also exposed to cyber threats. The Software Engineering Institute of Carnegie Mellon University warns about the increasing vulnerabilities of hospital devices, clinic networks, and patient data. If a device directly connected to the patient gets compromised, it could easily mean the loss of life. With medical records being largely online, hackers have been exploiting the lack of proper security defences to gain access to sensitive data in these records.

5. Cryptojacking

This is a cybercrime trend in which hackers hijack third-party homes or work computers to fish for cryptocurrency. They secretly make money by linking themselves to someone else’s system. Cryptojacked systems lead to performance issues and expensive downtimes for companies since it costs a lot to track and fix these issues.

6. Semi-autonomous Vehicles

The invention of connected cars has increasingly enhanced passengers’ comfort. These cars use onboard sensors to optimize their operations. They are becoming more and more popular with the advancement of technology. However, this also exposes cars to cyber threats and makes them easy targets for hackers. They exploit the vulnerabilities in these cars and steal sensitive data or harm drivers. This leads to safety and privacy concerns in connected cars.

7. Man in the Middle Attack (MitM)

This refers to a form of cyberattack in which the attacker sets up a position between the sender and the receiver and intercepts the messages or changes them in transit. All the while, the sender and receiver believe that they are communicating directly. This might be used in the military to intercept enemy signals.
