How to Defend Against Unwanted Calls and Phone Scams

A complete and intuitive guide to block unwanted calls for ever on both your home phone number and your smartphone

For lunch, dinner and even at work. Our day is marked by phone calls. Both the home and the smartphone. In most cases they are not good news but the usual call centers that try to sell us everything. Let us see then, with this complete guide, how to defend ourselves from unwanted calls.

There are a number of ways to defend yourself on the fixed line from unwanted call center calls, but also and especially to avoid unpleasant phone scams. To stop the continuous promotional calls we can decide to subscribe to the public register of the opposition. But it’s not the only way to defend ourselves from the insistent calls of telemarketing. In fact, now even smartphones have become a target of promotional calls, and you need to install the right applications to be able to block unwanted phone calls.

How to register for the opposition

It is a service made available to the citizens that allows you to exclude your number from those available to the various call centers. To register the first thing to do is go online to the site Here we select the Subscriber Area that we find in green on the top left of our monitor.

Once entered the Subscriber Area we will notice a series of icons, five for accuracy. We have to click on the one with the word “Web”, which is also the first on the list. This way we’ll open a pop-up menu, and select the entry. Below we will read the words: “Dear subscriber, to subscribe via web your number in the public register of the opposition, you will have to fill out and send the electronic form at the following Link”. Clicking on the link we will be transported on a new page where we will fill in the necessary form. To complete the operation we will need our phone number, the VAT in case of company phone, our birth and residence data and an e-mail address. Once you have filled out the form click on the Send entry, in the lower left. At the end of the inscription display a summary page, remember to print it because it might come in handy in the future. If, in fact, after our registration continue to receive calls from the call center we can contact the guarantor for the protection of personal data and denounce the fact. To do so we download, always from the site of the register of oppositions, the file with the words “signalling receiving unwanted advertising calls – for private telephone users”. Fill it in and send it by registered mail to the address on the top right hand side of the form. Let us remember that the activation of the registration in the register of oppositions takes about 15 days.

Limitations of the Opposition Register

Registration to the register of oppositions will avoid us having to respond to different promotional and unwanted calls. But it may not solve the solution in a definitive way. Legally, in fact, even if we are enrolled in the opposition register, the companies that we have enabled to receive promotional communications can still call us. This is something that happens often when you sign up for an Internet site, participate in an online contest or subscribe to services of various kinds. We are always careful so when we release our number on the net and when we click “I agree” at the time of registration to sites, forums or social networks of various kinds.

How to block unwanted calls on smartphones

As we said the promotional calls, the unwanted and the attempts to scam now are no longer an exclusive phenomenon of landlines, but are also recurring on smartphones.

Facebook Under Attack, A Virus Steals Passwords

A software promises to steal the Facebook Passsword of your contacts, but actually installs a trojan that takes possession of your credentials.

August 14, 2017-talk of Dante’s retaliation, in cases like these, is almost an obligation. As noted by some security researchers from the Australian company LMNTRIX Labs, a Facebook malware allows hackers who have created it to steal the credentials of access to the social network of unwitting victims.

Up here there would be nothing new or exceptional: of viruses on Facebook are counted to dozens every day and are able, who more who less, to endanger the data of users enrolled in the social network of Mark Zuckerberg. The peculiarity of the discovery of Australian researchers is another and lies in the “form” with which the virus is rapidly spreading. To deceive users, the malware promises (in disguise, of course) to help steal the Facebook password of their contacts. Instead, the exact opposite happens: once installed, it steals the credentials of the infected computer. Retaliation Dante, in fact.

The virus that promises to steal Facebook password

Behind what might look like a “simple” hacker attack lurks, instead, a complex social engineering operation. The cyber criminals who created it, explain the Australian computer security researchers, have well understood that some “poorly licit” operations could attract the attention of many Internet users around the world. They have decided to “disguise” the Facebook virus from software that allows you to steal Facebook passwords and access, so, to the profile of your friends or acquaintances.

As said, instead, Facebook Password stealer – This is the name chosen for malware – installs a Trojan inside the computer that allows hackers to get hold of the credentials of the unsuspecting victim. In addition, they also put on an online marketing campaign, with advertisements on sites and forums of various kinds.

How does the virus Facebook Password stealer

Although the stratagem devised to promote the spread of the Facebook virus is rather complex, its operation is elementary (or almost). In the software screen there are three fields to fill: two dedicated to their credentials to access the social network, while the third one is used to know the URL of the profile “objective”. The truth, however, is that as soon as you click on the button “hack”, the data entered in the first two fields will be “taken over” by the Trojan Horse installed on the PC and sent to the server managed by hackers.
How to defend yourself from the Facebook virus that steals passwords

Real defense tools against this particular Facebook virus don’t seem to be there. At least for the moment. The only thing to do is to avoid downloading “abnormal” software that promise to obtain impossible results: to be able to steal Facebook password knowing only the user name of the profile “objective” is actually not possible. If you run into one of these programs – which promise to recover or steal Facebook passwords – keep yourself well away: behind it hides something unclear.
