Incomprehensibility of the terminology

Turn to technicians in the field to try to understand what a malware, is not always the best solution, because (in most cases) the concepts expressed by the same may be so steeped in technicalities as to be absolutely incomprehensible to most people.

As soon as they use in their explanations concepts such as viruses, worms, Trojan, Spyware, Backdoor, Rootkit, Phishing, and Botnet Ransomware, users with little knowledge on the subject renounce groped to understand the content of the conversation almost on the spot.

These categorizations are still primarily useful for comparisons academic and specialist.

The two “families” of malware that most interest and involve companies and users nowadays are certainly:

  • Spyware: Malware with the intent to spy on a user’s online activities and steal credentials and other sensitive information of the user (typically bank access);
  • Ransomware: Malicious software that attack by limiting device access it infects, demanding a ransom to be paid to remove the limitation, e.g. the famous: Reventon and cryptolocker.

Malware definition

As part of the company’s information security, malware (full: malicious software) is simply a program to carry out illegal activities to the detriment of other users.

In general line such activities may, for example, result in the theft of sensitive information, access to private systems or unlawful in the possibility of disturbing and altering the operations carried out by another person’s computer.

Malicious software is a concept born in 1990 to Yisrael Radai, which identifies an activity able to illegally steal private or commercial information. Practice usually a time to cause damage to PCs and systems or to encrypt victims data extorting money for decryption.

To better understand what a malware, suffice it to say that it indicates a multitude of intrusive software that can infect files that are not malicious. Although these programs may take the most varied forms, often in the form of virus (Worm, Trojan, Spyware, etc.).

Why they are carried out this kind of action?

Although, when it comes to corporate computer security, malware is regarded as an action carried out to obtain direct profits or invade another privacy, in reality the reasons that can push someone to create malicious software are varied.

Now speak of simple piracy is totally obsolete. The two major categories in which fall the reasons are easily identifiable to the rumors: cyber crime and intelligence.

In the world “intelligence”, the malware is used in a targeted way and being spied upon by a government or, more probably by a rival company is an act “personal” but not likely for the common user but not impossible.

On the contrary, in the world of “cyber crime”, 99% of the malware is used to “trawling” of common victims, with little cost and a lot of economic performance. And an activity that is particularly adapted to the organized crime of medium-small size.

To be affected, in most cases, is therefore not a personal matter but something that falls under the law of large numbers. It is no coincidence that the first web attack on 3 hit a small business!

Of course, with the times they live in, protecting corporate IT security is not easy, but having a clearer idea of ​​the threats in circulation, you greatly reduce your chances of being victims of cyber pirates.

How to defend against malware?

Sure, a few lines cannot provide a shield against such a massive phenomenon, but we try in some places to summarize the major defenses that we can erect against malware and malicious.

Defense through software

It may sound trivial, but often it is the lack of any Antivirus the leading cause of infection, together with the use of software and outdated operating systems.

Equip each device of an antivirus software, update applications consistently and avoid using crack software (increasingly being used by malicious people to cyber attacks) can be a sufficient defense for the majority of generic attacks through malware.

Defense through knowledge and training

The speed with which new malware is produced is sometimes higher than the refresh rate of the software houses. In this case, the software is not enough defense and the only other bulwark remains the defense in person by the user. Learn to recognize potential hazards and traps is essential to avoid ending up burned.

3 The areas usually more sensitive …

  • Email management: E-mail messages are the quickest and easiest vehicle for these attacks, you must then learn to recognize the messages with malicious intent. Be wary and always think twice before you open an attachment or click on a link came from an unknown sender or suspected.
  • Download the application: Always extremely cautious when downloading software from unknown sites especially. Often malware they are also hidden in software masquerading as technical and IT solutions to problems!
  • Navigation: Even the simple web browsing can sometimes lead to fall into the trap. One of the things to which more attention is often when we are looking for an online information and that we are never given explicitly from the first source, but we are driven back with a link to another and from this to another ending in a maze of little-known web sites that may hide many traps.
