    What is cybercrime?

    Cybercrime is any criminal activity that involves a computer, networked device or a network.

    While most cybercrimes are carried out in order to generate profit for the cybercriminals, some cybercrimes are carried out against computers or devices directly to damage or disable them. Others use computers or networks to spread malware, illegal information, images or other materials. Some cybercrimes do both -- i.e., target computers to infect them with a computer virus, which is then spread to other machines and, sometimes, entire networks.

    A primary effect of cybercrime is financial. Cybercrime can include many different types of profit-driven criminal activity, including ransomware attacks, email and internet fraud, and identity fraud, as well as attempts to steal financial account, credit card or other payment card information.

    Cybercriminals may target an individual's private information or corporate data for theft and resale. As many workers settle into remote work routines due to the pandemic, cybercrimes are expected to grow in frequency in 2021, making it especially important to protect backup data.

    Defining cybercrime

    The U.S. Department of Justice (DOJ) divides cybercrime into three categories:

    crimes in which the computing device is the target -- for example, to gain network access;

    crimes in which the computer is used as a weapon -- for example, to launch a denial-of-service (DoS) attack; and

    crimes in which the computer is used as an accessory to a crime -- for example, using a computer to store illegally obtained data.

    The Council of Europe Convention on Cybercrime, to which the U.S. is a signatory, defines cybercrime as a wide range of malicious activities, including the illegal interception of data, system interferences that compromise network integrity and availability, and copyright infringements.

    The necessity of internet connectivity has enabled an increase in the volume and pace of cybercrime activities because the criminal no longer needs to be physically present when committing a crime. The internet's speed, convenience, anonymity and lack of borders make computer-based variations of financial crimes -- such as ransomware, fraud and money laundering, as well as crimes such as stalking and bullying -- easier to carry out.

    Cybercriminal activity may be carried out by individuals or groups with relatively little technical skill, Or by highly organized global criminal groups that may include skilled developers and others with relevant expertise. To further reduce the chances of detection and prosecution, cybercriminals often choose to operate in countries with weak or nonexistent cybercrime laws.

    How cybercrime works

    Cybercrime attacks can begin wherever there is digital data, opportunity and motive. Cybercriminals include everyone from the lone user engaged in cyberbullying to state-sponsored actors, like China's intelligence services.

    Cybercrimes generally do not occur in a vacuum; they are, in many ways, distributed in nature. That is, cybercriminals typically rely on other actors to complete the crime. This is whether it's the creator of malware using the dark web to sell code, the distributor of illegal pharmaceuticals using cryptocurrency brokers to hold virtual money in escrow or state threat actors relying on technology subcontractors to steal intellectual property (IP).

    Cybercriminals use various attack vectors to carry out their cyberattacks and are constantly seeking new methods and techniques for achieving their goals, while avoiding detection and arrest.

    Cybercriminals often carry out their activities using malware and other types of software, but social engineering is often an important component for executing most types of cybercrime. Phishing emails are another important component to many types of cybercrime but especially so for targeted attacks, like business email compromise (BEC), in which the attacker attempts to impersonate, via email, a business owner in order to convince employees to pay out bogus invoices.

    A list of the different types of cybercrimes

    Types of cybercrime

    As mentioned above, there are many different types of cybercrime. Most cybercrimes are carried out with the expectation of financial gain by the attackers, though the ways cybercriminals aim to get paid can vary. Some specific types of cybercrimes include the following:

    Cyberextortion:A crime involving an attack or threat of an attack coupled with a demand for money to stop the attack. One form of cyberextortion is the ransomware attack. Here, the attacker gains access to an organization's systems and encrypts its documents and files -- anything of potential value -- making the data inaccessible until a ransom is paid. Usually, this is in some form of cryptocurrency, such as bitcoin.Cryptojacking:An attack that uses scripts to mine cryptocurrencies within browsers without the user's consent. Cryptojacking attacks may involve loading cryptocurrency mining software to the victim's system. However, many attacks depend on JavaScript code that does in-browser mining if the user's browser has a tab or window open on the malicious site. No malware needs to be installed as loading the affected page executes the in-browser mining code.
