Top Five Cyber Security Vulnerabilities

Whether you’re a business or an average user, cyber security is always a matter of concern for you. Even big corporations and governmental agencies are not immune to such vulnerabilities. Cyber-crimes can have a far more devastating impact on any organization or person than a conventional attack since you’re not even aware of the location of the attacker or even the files and info that such attackers have gained access to.

The ramifications of such attacks are enormous, as the entire economy of a country may be put to risk if attackers target governmental agencies like banks or other financial institutions.

Thus, it is important to know about the vulnerabilities prevailing in cyber-world so that you could take preventive measure to avert such an attack. So, keep reading to find out five cyber-security vulnerabilities present in the contemporary online world.

1. Buffer Overflows

Buffers are sequential section of memory. Such sections store different character strings or even a set of integers. Buffer overflows happen when there is an overflow of data in a particular buffer of a defined length. The buffers are unable to handle such huge amounts, and hence, Buffer Overflows happen.

These attacks occur when the attacker is aware of the target’s space allocation system and buffer management. He can send a code with malicious data to the target system. Since the application will not be able to handle so much of data, hence it will use more buffer than allocated to it. This info is sent back to the hacker, and he can exploit this vulnerability in his favor.

2. Injection Vulnerabilities

This is a very common flaw and is quite effective for the hackers. In such a vulnerability, an application sends untrusted data to an interpreter. SQL, XPath, XML parsers, LDAP are some of the applications that are affected by it. Though, such flaws are very easy to discover through proper analysis of the code. But they are quite difficult to find when they are in “Testing situations”. Such attacks cause data loss which ultimately leads to loss of sensitive data. Even the entire control over the target computer can be accessed.

3. Sensitive Data Exposure

This situation occurs when some unauthorized person gains access to the sensitive data of the users. Sensitive data exposure, generally, happens when an ‘unprotected’ set of data is transmitted between different cyber-entities. Although, it can even happen when the data is at rest. The attacker could hack the data, or intercept such data. The primary reason for such attacks is the lack of encryption. If your organization’s data is not properly encrypted, then you may face the dangers of exposure of such data to the entire world.

4. DDoS attacks

DDoS (Denial of Service) Attacks are one of the most annoying things on this list. Such attacks are used to flood the target’s server with so much traffic that their servers crash. DDoS attacks can also be used as a smoke screen to divert the attention of the concerned IT team and carry out something even more dreadful. The attacks are getting advanced each day, and if proper actions are not taken then, it may even lead to many companies losing their data or even their customers.

5. Social Media Attacks

Social Media attacks are rampant today. Social media contents are used by the attackers to distribute malware or steal sensitive data. The attack is dreadful in the sense that it is very easy for the attackers to spread its effect to a large section in almost no time. Such attackers are in the constant hunt to device new technique to exploit social network vulnerabilities.


The attacks listed above are some of the most cyber-threats existing in the cyber-world today. Although, the list is neither conclusive nor comprehensive. There are other susceptibilities too like Broken Authentication, Session Management, and Security Misconfiguration, but here we have included only the most common threats.
