  • Macro viruses: these are often associated with excel and word files. The virus will come with the file and the moment you execute the macro the virus takes control of the application.
  • Trojans: they are often confused with viruses, but the main difference is that Trojans do not replicate themselves like viruses. They also can create backdoors for hackers to use. The Trojan can be hard to detect because it hides behind vital programs.

Denial of Service (DoS)

In recent years this has become a common form of cyber-attacks. The most common form of DoS attacks is when the hackers flood a company’s website with requests that is becomes almost impossible to serve the legitimate customers. There instances where the overflow in traffic is legitimate – for example when there is some breaking news. Differentiating the legitimate customers from the hackers can be a herculean task. Their instances where the hackers will use various computers with different IP addresses and this can prove a challenge to find the source of the attacks. While the attackers do not directly profit from the attack the times the company’s website is offline can cause serious damage when it comes to sales. In some instances, the hackers use a DoS attack as a conduit for other cyber-attacks.

Passwords Attack

Today we need a password for almost all online transactions. The attackers use several methods to snoop online for passwords. The easiest passwords to steal are those from unencrypted data sources. Hackers can also engage is some guessing work to get a password. Most people have created passwords using their names, children’s names, home addresses, and other personal information.

SQL Injection Attack

Through SQL companies can store large amounts of data in their servers. It stands for Structured Query Language. Since data is very sensitive hackers use this technique to get access to crucial information. They will often send a malicious code to compel the servers to give them vital information. Some of the information targeted include passwords, credit card details, user names among others. SQL injection attacks have often been used with ASP or PHP applications because they use old interfaces.

Cross-Site Scripting (XSS)

These kinds of attacks target the website users. Unlike the SQL injection attack that will target the database in this case the hackers will send a malicious code to a website and this code will capture information been sent by the website visitors. This code can be a JavaScript that pops up when you are log in to the site.
