This guide, originally written for Teslacrypt, has proved to be of some use to other ransomware as well, for example AVADDON (.avdn)

I add the following information, specific to the AVADDON virus:

  • There is NO way to recover files, given the methods used to encrypt them (any updates will be written in this same article)
  • DO NOT PAY, because it appears that the criminals DO NOT give the unlock code, it seems that it really does not exist and the criminals are NOT found in any way

Ransomware Infection

Let's start by establishing how you got the ransomware. The most known and used infection mechanism is the sending of a false email in which, in some way, you are invited to click on an attachment. And there are many ways to hide malicious code in an attachment, one of them is to send a zipped file which contains inside a js file (javascript) having the same name. This way it runs right away, and you're already screwed!

I received in Facebook this advertising (in Italian, but I think a similar thing may exist in any other part of the world):

Can't you watch Netflix or play your favorite video game because your Wifi is too slow?

Thanks to Wifi Booster you can:

✅ Increase the speed of your Wifi by 97%
✅ Extend the range of your wifi to 200 meters
✅ Watch movies or play online for up to 7 people ...

And I immediately become suspicious, also because it is NOT POSSIBLE TO INCREASE the speed of the home wifi. The maximum possible speed is the one you arrive at by connecting a cable to the router and checking with a speed test site.
When you connect a wifi, a certain loss of signal is physiological, and the further you move away from the router, the more the signal loses quality and, therefore, the speed of the wi-fi drops.
What can be done is only one thing: take the signal where it is still good and repeat it in the rest of the house. And it is what this object does, infact it's just a normal wi-fi repeater.

I connected to the site to which this advertisement referred, and I did not find any Italian VAT number. I looked for who the domain was registered to, and I didn't find it.
I look at the price and understand everything. This item "with the fabulous 50% discount" is on sale at 59 € !!

I don't add anything else, you can check for yourself, on amazon or on another site, how much a good wi-fi repeater should cost. (I tell you, about 30 €, and take a good one)

In the photo below you can see the real price of the repeater in question (at least: the photo is the same)

I publish a short note to explain what it is: Social Engineering is defined as a set of actions with which one tries to obtain sets of information concerning one, or more, people, usually with illicit purposes.
For example, someone can follow your computer tracks, on various social media, and also in your other public expressions on the net (forums, comments, blogs ...). In this way he can get an idea of ​​who you are, and you can discover some of your characteristics.

By creating special fake accounts, those who do social engineering could directly talk to you, and therefore have access to further personal information.

It is not said that you are the main target of these people, but sometimes you could become one. Do you know how? I will give you an example:

The attacker could make a first generic search: he could create one or more fake accounts, create a network of friends asked at random, and from there identify the subjects less attentive to the protection of their data, Yes, because accepting friends from unknown people , denotes at least some easiness, and certainly little attention to your data. That's why this could get you into the sights of more dangerous actions, to steal your data.

In fact, every information obtained is a piece to reach other more important information.

Usually, collecting this information has illegal purposes, such as fraudulently accessing the most sensitive information, based on the data already in possession, and therefore trying to enter your e-mail / social media / profiles and everything that is possible, even in your bank accounts.
