More people have access to the internet than ever before. This has prompted many organizations to develop web-based applications that users can use online to interact with the organization. Poorly written code for web applications can be exploited to gain unauthorized access to sensitive data and web servers. That is an interesting and useful information we would like to share with you. So let us go through the most popular hacking techniques for you.
Hackers can pull off many different types of hacking attacks like:
Phishing:– Phishing is a method where the attacker replicates the original website and then leads a victim to use this fake website rather than the original one. Once the victim enters their credentials into this website, all details are sent to the attacker. This method can be used to obtain payment information such as credit card data or personal information such as login credentials to important accounts and websites.
Another type of social engineering is the ‘bait and switch’ attack. In this hacking technique, attackers buy advertising spots on trustworthy and popular websites and put up seemingly legit ads. Once the ads are launched, users click on it only to find themselves inside a website that is filled with malware. These malware gets installed on the victim’s system and then the attacker has a free run within their system.
SQL Injection attacks:- SQL Injection attack is the most common website hacking technique. Most websites use Structured Query Language (SQL) to interact with databases. SQL allows the website to create, retrieve, update, and delete database records. It used for everything from logging a user into the website to storing details of an eCommerce transaction.
An SQL injection attack places SQL into a web form in an attempt to get the application to run it. For example, instead of typing plain text into a username or password field, a hacker may type in
‘ OR 1=1.
If the application appends this string directly to an SQL command that is designed to check if a user exists in the database, it will always return true. This can allow a hacker to gain access to a restricted section of a website. Other SQL injection attacks can be used to delete data from the database or insert new data.
Hackers sometimes use automated tools to perform SQL injections on remote websites. They will scan thousands of websites, testing many types of injection attacks until they are successful.
Session hijacking:– Session hijacking is an attack where a user session is taken over by an attacker. A session starts when you log into a service, for example your banking application, and ends when you log out. The attack relies on the attacker’s knowledge of your session cookie, so it is also called cookie hijacking or cookie side-jacking. Although any computer session could be hijacked, session hijacking most commonly applies to browser sessions and web applications. In most cases when you log into a web application, the server sets a temporary session cookie in your browser to remember that you are currently logged in and authenticated. HTTP is a stateless protocol and session cookies attached to every HTTP header are the most popular way for the server to identify your browser or your current session.
To perform session hijacking, an attacker needs to know the victim’s session ID (session key). This can be obtained by stealing the session cookie or persuading the user to click a malicious link containing a prepared session ID. In both cases, after the user is authenticated on the server, the attacker can take over (hijack) the session by using the same session ID for their own browser session. The server is then fooled into treating the attacker’s connection as the original user’s valid session.
DDoS:- (Distributed Denial of Service) attacks are a curious phenomenon because the malware used to perform them doesn’t really hurt the person infected by it. Instead, it turns their device into one small part of an army of bots that the hacker then uses to completely flood their target with fraudulent requests and shut their server down.
The defence mechanisms for DDoS differ for bots and targets, and we’ll primarily be discussing the bot end of the equation. For a member of the bot army, the damage actually isn’t that significant. Besides the fact that having malware controlled by a hacker on your device is highly insecure, all the DDoS bot does is gobble up a fraction of your online bandwidth whenever it’s called on by the hacker to participate in an attack. Despite this, it’s still a good idea to do the world a favor by preventing your devices from becoming part of an organized attack. Can NordVPN protect you? IT DEPENDS. NordVPN’s Cybersec feature blocks your computer from connecting to botnet command and control servers, which hackers use to mobilize their armies. This will isolate the bot from its owner and prevent it from attacking others, but you’ll still need an anti-malware program to remove any bots you might have.
