Certainly, if you are a director of a company or if you have a power of attorney at business accounts. Then you belong to the favorite targets of cybercriminals. We all know how cleverly and in an organized way fraudsters work.

These attacks are often encrypted in order to escape detection. Once their target is reached, hackers attempt to download and install malicious software on the compromised system. In most cases, the malware is used new, advanced versions that traditional anti-virus solutions are not yet able to identify.

We’ve listed below few significant strategies and tools used by cybercriminals to infiltrate your network as well as ways to fight against them.

They act as they are calling on the behave of auditors, certified public accountant or a government research service. This way, they are able to collect information about your company’s internal payment procedures. After that, they contact a staff member who has power of attorney to make large payments. They then act as the CEO or CFO of the company and invent a story about a possible foreign acquisition, a difficult tax check or other scenario for which, urgently and confidentially, a large sum of money has to be transferred to an account still never used. Employees who is use to receive a personal call from the CEO are chosen. Sometimes they even go for an external consultancy to increase their credibility.

Unfortunately, many companies do not have the right tools to deal with these attacks.

With hundreds of new malware variants developed every hour, organizations need up-to-date, real-time protection against the latest threats. An effective security solution must be continuously updated 24/7. In addition, the available memory on firewalls is insufficient to support the considerable number of types and variants of malicious software.

To be effective, firewalls need to use a network sandbox and the Cloud to provide wider visibility of threats, discover new variants, and improve detection. In addition, ensure that your security solution supports dynamic update protection not only at the firewall gateway, but also at mobile and remote endpoints and your e-mail.

In fact, new threats emerge every hour on every continent. Most hackers use an approach similar to that of burglars: they infiltrate, take all they can and go out before someone triggers the alarm. Once succeed, they reproduce this attack on another system.

Others proceed more insidiously and slowly to access larger amounts of data over a longer period of time. Some attacks arrive via the Web, others by e-mail, or enter the network via infected devices that were previously outside the network security perimeter.

Finally, while a single firewall can identify and block threats based on their origin, a sophisticated firewall incorporates botnets filtering functions to reduce exposure to known global threats.
