What is Cybercrime?

Cybercrime encompasses any unlawful activities involving computers, networked devices, or networks themselves. Cybercrime in simple words is a type of a digital crime frequently perpetrated by cybercriminals or hackers seeking financial gain, while political or personal reasons can also drive such acts. Individuals and organisations alike can engage in cybercrime, where the level of technical expertise among criminals may vary significantly.

Common Types of Cybercrime Explained

Cybercrime can take many forms, including:

  • Email and internet fraud: These encompass various cybercrime activities aimed at deceiving or defrauding victims. One prevalent method is phishing, in which individuals receive deceptive emails that mimic trustworthy entities. These fraudulent messages aim to trick recipients into divulging sensitive information such as passwords or credit card details.
  • Identity theft: In this form of cybercrime, hackers engage in stealing personal information. This includes vital details such as Social Security numbers, addresses, or date of birth with the purpose of assuming the victim's identity. By acquiring this stolen identity, perpetrators can carry out fraudulent activities like applying for credit or making purchases under the victim's name.
  • Financial data theft: Thieves targeting financial or card payment data pose a significant threat in the digital realm. Cybercriminals often focus their efforts on acquiring sensitive information, such as bank account details and credit card credentials. The reasons behind these illicit actions vary: someone might exploit the stolen data to carry out unauthorised transactions, while others may opt to sell it on the dark web for use by fellow criminals.
  • Cyberextortion: Involves cybercriminals demanding money from individuals or organisations. They use threats of causing harm or releasing sensitive data if their demands are unmet. The threats can vary from launching cyberattacks against company networks to publishing personal data stolen from individuals.
  • Ransomware attacks: In these malicious acts, a potent form of malware locks away the victim's valuable data by encryption. Subsequently, the cybercriminal behind it initiates their demand—often in cryptocurrency—in exchange for decrypting this precious information. Failure to comply with their request may lead to irreversible loss or publishing of personal data.
  • Cryptojacking: Involves hackers utilising a victim's computer processing power without their consent for mining cryptocurrency. This unauthorised activity not only significantly slows down the victim's computer but also results in increased electricity usage.
  • Cyberespionage: Refers to unauthorised access to government or company data, often motivated by political or commercial advantage. It involves targeting sensitive information, ranging from state secrets to intellectual property. Perpetrators can either be state-sponsored actors or corporate spies.

DoS vs DDoS Attacks

One form of cybercrime commonly encountered is the Denial-of-Service (DoS) attack. In this type, cybercriminals obstruct users from accessing a website or network by overwhelming the server with excessive traffic, rendering it inoperable.

There exists a variation known as Distributed Denial-of-Service (DDoS) attack, where multiple remote machines are utilised to launch the assault. This approach enables faster deployment and presents greater challenges in terms of its detection and shutdown.

Cybercrime Targeting Finance

Cybercriminals often target financial institutions due to the valuable data they possess. These criminals employ various tactics, such as hacking into bank accounts to directly pilfer money or resorting to social engineering scams, deceiving individuals into transferring funds.

Additionally, they engage in data theft for identity fraud or sell the acquired information on the dark web. In certain instances, hackers exploit ransomware or launch DDoS attacks to extort money from these establishments.

Final thoughts

In conclusion, it is essential to acknowledge the significant threat posed by cybercrime. However, by gaining an understanding of its nature and implementing appropriate preventative measures, individuals can significantly reduce their risk. The key lies in staying informed, remaining vigilant, and understanding the high meaning of cybercrime prevention in the digital realm.
