Find more about the different kinds of cyberattacks that companies encounter these days and how to protect yourself, your data, and your company from them.
Cyberattacks may be quite expensive for the people and businesses they affect. The FBI Internet Crime Report states that in 2022, cyberattacks resulted in a sharp loss of $10.4 billion. Cybercrime will remain a major worry as this figure is only predicted to rise in the upcoming years.
Cyberattacks are becoming more frequent due to a number of variables. For instance, the cost of averting cyberattacks has gone up due to inflation, making certain businesses susceptible as they struggle to integrate cybersecurity measures into their budgets. Cyberattacks with political motivations have also increased as a result of global geopolitical turmoil.
This post will discuss cyberattacks, the different kinds to be aware of, and your options for defending your company or yourself.
An attempt to steal, modify, destroy, interfere with, or disable information resources and systems found in computer networks and systems is known as a cyberattack. Insider threats and external threats are the two types of cyberattacks. Insider attacks originate from people who have authorized access to the systems they target and who take advantage of that access to maliciously or unintentionally exploit vulnerabilities. These could be carried out by a contractor having access to the company's systems or by an irate or disgruntled employee. An outsider threat comes from someone like hackers or criminal organizations who have no connection to the system they are assaulting.
Who do cyberattackers target?
Cybercriminals frequently target the healthcare, government, nonprofit, and finance sectors. Attackers have a tendency to target the healthcare sector in particular. This is a result of the fact that many people's personal data are accessible to healthcare organizations. Because the infrastructure of the healthcare industry is so important, ransomware attackers know that these companies will probably comply with their demands without delay.
Governmental institutions are also vulnerable to hackers since they handle sensitive data, including social security numbers. Because of their unique position and access to financial information from contributors and fundraising activities, nonprofits are prime targets for hackers. Because they have access to large sums of money, financial organizations like banks and insurance firms are frequently the targets of extortion and theft.
Common types of cyberattacks
Cyberattacks can be carried out for purposes other than profit. Certain cyberattacks aim to access or destroy important data.
Cyberattacks of the following categories are common and affect both individuals and organizations:
Malware
Cybercriminals gain access to your system's data by using malware, which includes viruses, ransomware, spyware, and worms. Malware can install itself and activate on your device when you click on a malicious attachment or link.
Spoofing
Cybercriminals occasionally pose as individuals or businesses to deceive you into divulging personal data. This can occur in a variety of ways. Using a phony caller ID to conceal the phony number from the recipient of the call is a popular spoofing tactic. Using a fictitious domain name, fabricating a website, or interfering with facial recognition software are some further spoofing techniques.
Backdoor Trojan
Reverse door Trojan assaults involve malicious software that can install malware or data on your computer system under false pretenses and create what's known as a "backdoor." Without the user knowing, attackers can take control of the device using the backdoor.
Ransomware
Malicious software known as ransomware is what hackers might put on your computer to prevent you from accessing it until you give them a ransom. However, paying the ransom doesn't ensure that the software will be removed, thus experts frequently suggest that people avoid doing so if at all feasible.
Password attacks
A password assault might be as easy as someone figuring out your password correctly, or it can include more sophisticated techniques like keylogging, in which hackers track the data you input and use that data to detect passwords. The previously mentioned phishing technique can also be used by an attacker to pose as a reliable website and attempt to trick you into disclosing your account information.
Internet of Things attack
Applications and software on IoT devices, as well as communication channels between linked IoT components, are vulnerable to assaults. Attackers can target a bigger attack surface since IoT devices may have weak security measures and are connected to one another through the internet.
Cryptojacking
The act of obtaining unauthorized access to a computer system, commonly via malware that permits the attacker to utilize the computer's resources for cryptocurrency mining, is known as "crypto-jacking." Attackers can circumvent the high operating costs associated with cryptocurrency mining by using cryptojacking.
Drive-by download
Quick download Attacks happen when malicious malware is downloaded to your device via a website, app, or operating system that has weak security features. This implies that even if you do nothing wrong, you could still fall prey to a drive-by download because it can happen because a website you trust to be secure has lax protection.
Denial-of-service attack
A denial-of-service attack overloads a device or operating system with so much traffic that it crashes and shuts down completely. This is not a common strategy used by attackers to obtain information. Rather, the victim must invest money and time to restore their systems to functionality. This is the approach that cybercriminals usually choose when their target is a government agency or trade association.
How to prevent cyberattacks
Being aware of the possibility of cyberattacks for yourself and other staff members at your company is a crucial first step in preventing them. Ensuring the legitimacy of the email address and exercising caution before clicking links are important steps in safeguarding your data and systems.
The following are some helpful pointers to avoid cyberattacks:
Update your software.
Modern software systems are more robust than out-of-date ones, which could be more prone to flaws. It is best to have the most recent version of the software because updates can fix any bugs and weaknesses. Additionally, think about purchasing a patch management system to keep software systems updated.
Install a firewall.
Backdoors and denial-of-service assaults are two types of attacks that firewalls can assist in avoiding. They function by managing the network traffic that passes via your system. Additionally, a firewall will halt any unusual behavior that it determines could endanger the system.
Back up data.
Data backups involve moving the data to a different, safe location for storage. This could entail using a physical device, such as a hard disc, or cloud storage. Having a data backup enables you to retrieve any lost information in the event of an attack.
Encrypt data.
Data encryption makes sure that only people with the decryption key can access data, making it a popular method of preventing cyberattacks. It is difficult to break encryption because attackers frequently have to use the brute force technique, which involves attempting a variety of keys until they figure out which one works, to successfully attack encrypted data.
Use strong passwords.
To thwart assaults, you should create strong passwords and refrain from using the same ones across several platforms and accounts. Repetitively using the same password raises the possibility of providing hackers with complete access to all of your data. You can keep your accounts safe by changing your passwords on a regular basis and creating passwords that combine capital and lowercase letters, numbers, and unusual characters.
