Common types of cyber attacks and how to prevent them
Hackers are constantly looking for ways to penetrate security systems to threaten your personal devices and data from being attacked by criminals. From web browsers to operating systems and chat applications, there is nothing that cannot be targeted. It's a never-ending game in which developers constantly have to release patches to deal with vulnerabilities that security researchers discover.
At VPN Rice, our security team is always on the lookout for new types of cyber attacks. Most of these attacks can be classified into a few fixed categories, and if you know their target in advance, you can take specific precautions to ensure the security of your system. me.
Below, we'll explain some of the common types of attacks that individuals and businesses often encounter, along with some simple suggestions for protecting your identity, financial accounts, and personal data. .
1. Fraud
In 2022, there were more than 500 million reported cases of phishing attacks, making it one of the most common types of cyberattacks. Phishing attacks often require you to reveal sensitive information, such as your credit card details or login credentials. These are diverse attacks, in which the attacker uses different tactics. For example, they may send an email that looks like it's from a company you frequently do business with, asking you to click a link to log in to your account. But in reality, that link takes you to a website controlled by hackers, whose sole purpose is to collect your personal information.
Phishing attacks can also lead to the installation of malware or other attacks. They can appear everywhere: in emails, SMS messages, on social media accounts or even through phone calls. Attackers often use a sense of urgency or panic to motivate you to click on a link or download an attachment without giving much thought to safety. Sometimes, a simple click or file download can place malware on your device.
In the past, phishing attacks were easy to detect because they often featured poor email design or grammatical errors. Recently, however, we have seen an increase in the quality of these deceptions.
2. Counterfeit
Phishing attacks often use disguising email addresses, websites, or other forms of identification as a way to deceive users and steal important information or engage in unethical behavior. They leverage this reliance on fake information sources to achieve their goals, which include stealing data, hacking into your network, or getting you to download malware. Hackers often use spoofing to carry out other cyber attacks, such as phishing or man-in-the-middle attacks.
The SMTP protocol does not integrate any authentication mechanism, which has made spoofing a common attack in the past. In response to this, email service providers have developed authentication measures such as SPF, DKIM and DMARC to flag spoofing attempts as spam or prevent them from reaching your account. However, not all email services have these measures configured or implemented.
Domain spoofing attacks often try to make you believe you are visiting a familiar website, with the aim of spreading malware or making you reveal valuable personal information.
3. Malware
Malware, or malware, is a diverse category that includes a wide range of specific types of attacks. While most software helps you, malware has the opposite goal - it's specifically designed to harm you, your devices, and your network.
Different types of malware accomplish distinct goals, including stealing sensitive information, holding data hostage, or causing damage to system infrastructure. Hackers use a variety of attack methods to spread malware, including phishing attacks, downloads via disk, and you may not even know you have it installed. malware onto your device simply by visiting a malicious website.
4. Insider threats
In a corporate environment, people with access to your systems, whether they are employees within your organization or partners and contractors, pose a major threat to your security. . They possess two factors that hackers often take advantage of: your trust and access to your computer system.
Similar to external attackers, internal attackers can also perform threatening actions, including attacking with financial targets, stealing important information, and conducting espionage. or deploy malware on behalf of others. There are many famous examples of insider threats, including Uber's CEO's attempt to steal confidential commercial information from his former employer, Google. There are also situations that involve data breaches, and some even happen accidentally, like the case of a Microsoft employee who posted credentials internally on GitHub.
5. Man-in-the-middle attack
Just as its name suggests, hackers use man-in-the-middle (MITM) attacks to coordinate between parties in online communication, with the aim of eavesdropping on information exchanged or changing the experience of the parties involved. mandarin. Attackers can use this trick to steal sensitive information, deceive victims into performing unwanted actions, or interfere with communication content. MITM attacks can be carried out both on an individual level, such as a single hacker spying on a specific victim, or on a larger scale, as in the case of authoritarian governments spying on a specific victim. and direct citizens' internet traffic.
6. Social engineering
Social engineering may seem like a scientific name, but in reality, it is a clever method of deceiving others and motivating them to take desired actions, with the goal of revealing good information. gain access to the system. In social engineering attacks, hackers often pose as IT staff and request personal information in the name of "verifying your account" or distributing free USB drives that have been infected with software toxic.
Phishing techniques are designed to take advantage of people's mental weaknesses, they target emotions that can cloud judgment, such as fear or curiosity. These attacks have been implicated in many high-profile hacks. For example, in 2020, hackers used social engineering to steal the Twitter accounts of famous figures to promote Bitcoin-related fraud.
7. Distributed denial of service
A distributed denial of service (DDoS) attack is a form of cyberattack that primarily targets the websites and systems of enterprise organizations. Hackers leverage multiple compromised computers to simultaneously attack a company's servers by sending a large number of requests, effectively causing an outage.
Often attackers use DDoS attacks to demand ransom from victims, demanding a payment to stop the attack. However, sometimes, non-professional hackers can also use DDoS as a form of activity or simply to show pride.
For individuals, DDoS attacks are usually not a major concern, unless they cause significant disruption to the service you need. In case you are concerned about downtime, you should check the reliability of the service and ensure that the company has protections in place to prevent or respond to a DDoS attack. Businesses that are experienced in dealing with DDoS attacks have often invested a significant amount in infrastructure to prevent these attacks and ensure the continuity of their services.
How to mitigate cyber security attacks
1.Use strong passwords: Passwords play an important role as a first line of defense for your online accounts. Always use unique, long, and complex passwords. Strong passwords can be created and managed using a password manager.
2.Use two-factor authentication (2FA): If hackers can get your password, 2FA is the next line of defense. Many online services allow you to enable 2FA, which requires you to provide a second authentication information, usually a temporary code from an authenticator app on your smartphone.
3. Always update your software: Cyber attacks often take advantage of vulnerabilities in the software you use. When developers discover vulnerabilities, they develop patches and release software updates. Always install updates for your device and apps promptly.
4. Be wary of phishing attacks: Phishing attacks are increasingly difficult to detect as hackers become more sophisticated. Always be vigilant and never click on links or download attachments in emails or text messages that you do not expect.
5.Use security-focused services: Using a service with strong encryption helps prevent data theft from unprotected systems. At Rice VPN, we develop products with security as a priority, ensuring that your data is always end-to-end encrypted before being sent to our servers.
