Are they the new weapon of mass destruction?<\/li>\n<li>This feels straight out of a Terminator movie.<\/li>\n<li>What exactly is the Internet of Things?<\/li>\n<\/ul>\n<p>There\u2019s nothing more tempting for a hacker than ruining the day for a corporate giant\u2014especially if it means making headlines and getting TV coverage.<\/p>\n<p>So, the main motivation here is fame.<\/p>\n<p>To achieve it, all they need to do is use botnets to flood the targeted websites with requests.<\/p>\n<h2>Botnets?<\/h2>\n<p>Yes, botnets\u2014the new digital warriors. They don\u2019t tire, they don\u2019t eat, and they barely use up any ammo.<\/p>\n<p>A botnet is a network of computers or devices running automated software robots. The botnet creator remotely controls all infected computers or servers.<\/p>\n<p>From the comfort of their armchair, the creator programs these botnets to infiltrate our computers and, once inside, use them like mind-controlling parasites. The trick is, we don\u2019t even notice.<\/p>\n<p><a href=\"https:\/\/codewebbarcelona.com\/wp-content\/uploads\/2016\/10\/diseno-web-barcelona-internet-de-las-cosas-03-1.png\"><img decoding=\"async\" class=\"alignnone size-full wp-image-563\" src=\"https:\/\/codewebbarcelona.com\/wp-content\/uploads\/2016\/10\/diseno-web-barcelona-internet-de-las-cosas-03-1.png\" alt=\"diseno-web-barcelona-internet-de-las-cosas-03\" width=\"640\" height=\"394\" \/><\/a><\/p>\n<p>Let\u2019s say someone builds a botnet for malicious purposes. The first step is to infect millions of computers worldwide. Once that\u2019s done, the next step is to command the bots to do whatever the creator wants.<\/p>\n<p>Servers are simple in principle\u2014they store our websites and deliver them when we request them.<\/p>\n<p>A request can be as simple as visiting the JordiEnsenyatDisseny website to ask for more information. Signing up for your favorite museum\u2019s newsletter is also a request.<\/p>\n<p>When these requests happen organically, there\u2019s usually no problem\u2014server capacity is planned based on typical human usage.<\/p>\n<p>But if millions of computers around the world make requests at the same time, it\u2019s a different story. That\u2019s why bots are used. One person with bad intentions can wield the power of millions through botnets.<\/p>\n<p>To avoid becoming part of this, it\u2019s as simple as installing a good antivirus and, ideally, a malware detection program\u2014essential to keep your computer from joining a zombie network.<\/p>\n<h2>By 2020, the number of connected devices is estimated to reach between 22 and 50 billion!<\/h2>\n<p>&nbsp;<\/p>\n<p>But what\u2019s remarkable about this attack is that it was carried out through the Internet of Things.<\/p>\n<p>The Internet of Things refers to all those everyday devices that are now connected to the Internet.<\/p>\n<p>Today, there are countless products on the market with Wi-Fi and Internet connectivity.<\/p>\n<p>Refrigerators that notify you when food is about to expire, sneakers that upload your stats to the cloud, smart toys for kids&#8230;<\/p>\n<p>These devices have huge potential, but very little protection against malware attacks. They\u2019re a double-edged sword.<\/p>\n<p>That\u2019s how the attack happened: the Wi-Fi of millions of infected video cameras was used to overwhelm Dyn\u2019s network via Mirai.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The Internet of Things This week, a news story broke that left everyone stunned\u2014the level of surprise seemed to depend on how much we know about the Internet.
