Hacking is gaining unauthorized access to a computer and viewing, copying, or creating data with the intention of destroying data or maliciously harming the computer. Nowadays, hacking is a growing threat for every business-large, medium and small. Hackers can impact any business at any time by stealing private data, taking control of a computer or by shutting down its website. It is a major concern for web development companies. Hackers can attack and threaten security of a business and its website in so many ways as follow:
DDOS Attack – Distributed Denial Of Service Attack:
- In this attack, a server or a machine’s services are made unavailable to its end-users. And then hacker proceeds to compromise the website of a business when the system gets offline.
- The example of a DDoS attack is sending many URL requests to a website in a very small amount of time. This causes overflowing at the server side because the CPU just ran out of resources.
Remote code execution Attack:
- This attack takes place as a result of either server side or client side security weaknesses. This attack is mostly seen in application development companies.
- Weak components include libraries, remote directories on a server that have not been monitored and other software modules that run on the basis of authenticated user access.
- These components which are used by applications are always under attack through things like scripts, malware, and small command lines that extract information.
DNS Cache Poisoning:
- It involves old cache data that a company might think it no longer has in its computer but it is actually there.
- Hackers identify weaknesses in a domain name system (DNS) which allow them to divert traffic from genuine servers to a fake website.
- This attack is major concern for web development companies.
- This is also known as UI Redress Attack commonly seen in Web development companies in India.
- The attacker is hijacking clicks that are not meant for the actual page, but for a page where the attacker wants you to be.
Cross-site Request Forgery Attack:
- This attack happens when a user is logged into a session and a hacker uses this opportunity to send them a fake HTTP request to collect their cookie information.
- Once the browser session of a user is compromised, the hacker can initiate requests to the application that will not be able to differentiate between a valid user and a hacker.
- Injection Attack occurs when there are flaws in SQL Database, SQL libraries or the operating system itself.
- Employees of application development companies open seemingly credible files with hidden commands or injections unknowingly.
- By doing this, employees have allowed hackers to gain unauthorized access to private data such as cardholder data or other financial data.
Cross-site scripting Attack:
- This attack is also known as XSS attack.
- It occurs when an application, URL “get request”, or file packet is sent to the web browser window and bypassing the validation process.
- Once an XSS script is triggered, it makes users believe that the compromised page of a specific website is genuine.
- It is a major threat for web development companies.
Social Engineering Attack:
- It happens when you disclose private information in good faith, such as a credit card number, through different communication ways such as chat, email, social media sites or virtually any website.
This article is helpful for web development companies to prevent them hacked by hackers. Every business should implement countermeasures for all above attacks.
