How Hackers Trick and Exploit Damaged SQL Server Systems?

Damaged SQL server systems are an open door for hackers to exploit and have direct access to your business files.

Damaged SQL server systems

Whether using a security testing tool or manual poking techniques, malicious attackers use various tricks for breaking into damaged SQL Server systems.

These systems having firewalls inside and outside are vulnerable to these hacks and attacks. The fact remains that if hackers are performing such a task, you must carry out similar attacks to test the safety and security of the existing system. For this, you must have a comprehensive understanding of hackers’ tricks for gaining access and violating the system running on SQL Server.

Direct Connection through the Internet

Direct connections help attain access to SQL Server that does not possess firewall protection and the entire world sees it. If you go by recent reports, you will understand that millions of systems lack this firewall protection, and therefore sit idle and wait for the attack. It is hard to understand the reason behind such a casual approach of users. You expose your system to critical server issues that provide direct access to the hacker using the Internet for such malicious purposes. These attacks may lead to a buffer overflow, service denial, and more. Remember that the effect of these attacks will further affect the vulnerability of the SQL Server system, and you might have to compromise on an essential database.

Vulnerability scanning

For revealing weakness in the underlying operating system, vulnerability scanning is necessary. In most cases, the database system and web applications use them. Various techniques like SQL Server patches, IIS or Internet information service, and SNMP are open to exploitation by uncovering the system through several methods. Hackers and attackers use several methods for gaining access to the database. It creates havoc in the system as they use open sources, commercial tools, and home-grown equipment for such tasks. Some of them even use the hacks manually from the command prompt. For preventing such a situation, you may use a commercial vulnerability tool. That will assess the system and provide you with relevant information. These are easy to use, provide comprehensive assessment, furnish your best results, and make the system secure.

Emulate server resolution services

If you want to discover a remote database, you can run UDP port 1434 and probe deep into the computer. There are other great tools used for looking into the SQL Server system and determining the version number. Even if you see the SQL Server not working according to the default port, these tools might be helpful. If there is a buffer overflow, you can use these current tools to address the current issue and resolve the problem.

Crack the password

Another favorite attack used by hackers is deciphering the SA password. It gives them an inlet into the SQL Server database and hampers the entire system. There are commercial products available that professionals often use to increase the capability of the system and the password. These are handy tools that are effective enough for protecting the system from these attacks.

Direct exploit attack

Tools like Metasploit help in case of direct attacks. These are known as silver-bullet hacks used by attackers for penetrating the system and undertaking code injection or gaining access to the command line. It is a commercial equivalent used for exploiting different vulnerabilities discovered during vulnerability scanning.

SQL injection

Another favorite attack of hackers is SQL injection. It gets executed through a front-end website application that does not validate the user input. Deformed SQL examinations, like SQL commands, may be inserted into the web URL, and the command gets executed. There are manual attacks if the hacker has a lot of time. To prevent such an emergency, professionals often undertake analysis of the system to discover potential SQL injection vulnerabilities. Performing these tasks is time-taking and complex as it encompasses automated tools. These dynamics only get comprehended by high-tech individuals who have the necessary knowledge and expertise in this field. They know how to discover the vulnerabilities and the best way of solving the issue.

Blind database injection

These attacks exploit backend SQL Server and web applications similarly to standard SQL injection. However, the attacker does not get feedback in the form of error messages in this case. These attacks are slow compared to SQL injection because of the guesswork involved. Hackers often use high-quality tools for introducing these attacks, which are difficult to break and resolve.

Reverse engineering

The reverse engineering method is like software exploit and memory corruption weakness. These are unique tools used for getting public accessibility to a system. Various examinations and processes help break into a system by cracking the password, playing with the vulnerabilities, employing the weaknesses of the underlying system, etc.

Pursue source code

Source code may provide information on damaged SQL or Server corruption. Specifically, developers store SQL Server essential information in the ASP script for simplifying the authentication procedure. By way of a manual assessment, uncovering the data is only a matter of a second. Hence, hackers often use this method to access the website by using source code.

If you do not compact the data periodically, it may lead to fragmented indexes and data, unpredictable queries, unreliable statistics, and much more. Try to utilize eliminated space in the PC by storing essential data and removing unnecessary statistics. These are some steps that you may take to ensure the system’s functionality.

An average computer user may not be competent enough to deal with the issue in all these situations. They do not have comprehensive know-how of technical concepts and problems. Although you have software available in the market, they may not provide you with high-quality results. If you want to assure the safety and security of your database, the best way is to get in touch with professionals. These IT professionals are reliable sources that assess the system and help you with probable solutions.

Hence, investing money in these resources will never go to waste. Hire professionals to safeguard your system and protect your data and server in the best possible manner. Hacked data can create several issues putting your enterprise at risk.
