With the income statement campaign just around the corner an attempt has been detected hacking massive that uses the Tax Agency as bait. At the moment two variants of the attack have been detected, although in both cases email is being used as a distribution system.

East campaign of hacking has been detected by Anexia Technologies that warns that despite the fact that it has been common with the start of the campaign for the declaration of income, fraudulent emails are received, This new attack is alarming because it involves not only identity theft, but also encryption of information. of computers and mobile phones.

The modus operandi: phishing and trojans

In the report, the experts who have detected the attack assure that at this time there are two variants: one that uses the phishing to steal your identity and another that installs a Trojan It encrypts your device information so you can’t access it until you pay a ransom. In both cases emails that pose as the Tax Agency are used.

In the case of TrojanAs explained by Asevera Eduard Requena, the email takes you to download a file that, once opened, encodes all the data on the computer so that its owner cannot access them. From there he is blackmailed into paying a ransom (which can go up to 1,000 ) to recover your computer. A payment that does not always end up solving the problem since, according to Requena, there are cases in which the companies that have suffered the attack end up paying for fear of losing the information and still do not receive the decryption key

In the variant of phishing It is not a question of blocking access to the information, but rather that they try to obtain all the personal information possible and then use it against the victim. There have been cases in which an email is received informing the victim of an alleged refund by the Treasury and asking for personal and bank details.
