When looking for new cyberattack forms, invaders are using artificial intelligence more and more. One of the areas of great concern is the deepfake area, which uses AI to impersonate real audio and video of real persons which can deceive or help deceive careless users.<\/p>\n\n\n\n

The term \u201cdeepfake\u201d comes from the underlying technology \u201cdeep learning\u201d, which uses machine learning and artificial intelligence to create the voice or a video of a synthetic human. Deep learning algorithms recognize patters from an extensive data bank that are then used to manipulate image, video, or audio, creating a false realistic appearance.<\/p>\n\n\n\n

How is this used and what are its dangers?<\/h2>\n\n\n\n

Although the ability to swap faces automatically to create manipulated videos with a real, trustworthy look has some positively interesting applications (such as films and gaming), this is obviously a technology that brings some problems.<\/p>\n\n\n\n

The use of deepfake to manipulate images from politicians and celebrities were the first, most controversial experiences with this technology. In 2018, for instance, a Belgian political party disseminated a video where Trump was giving a speech asking Belgium to withdraw from the Paris Agreement. Trump never gave that speech, it was deepfake. This is one of the dangers of this technology: disseminating false content as authentic content.<\/p>\n\n\n\n

In a corporate setting, deepfakes boost social engineering when used to manipulate people to get unauthorized access to systems, infrastructures, or information. By using this technology, attackers can, for example, combine e-mail phishing with fake audio messages. By using multiple vectors, they are increasing the chances of deceiving users.<\/p>\n\n\n\n

How to detect a deepfake?<\/h2>\n\n\n\n

As deepfakes become more common, society is more aware of this type of techniques and their use, being able to detect possible fraud attempts.<\/p>\n\n\n\n

To protect yourself, we recommend that you pay attention to some of these indicators that are indicators of deepfakes:<\/p>\n\n\n\n
