This adjustment aims to <strong>protect<\/strong> users against <strong>SMS scams<\/strong> and <strong>phishing attacks<\/strong>. <\/p>\n\n\n\n<p>The functionality, which prevents the cell phone from communicating with <strong>mobile network station simulators<\/strong>, was detailed in an article on the Google security blog, written by Nataliya Stanetsky and Roger Piqueras Jover.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"o-perigo-das-estacoes-base-falsas\">The Danger of Fake Base Stations<\/h2>\n\n\n\n<p>To the <strong>Fake Base Stations<\/strong> (FBS) or <strong>Stingrays<\/strong> are devices that create a parallel mobile network. <\/p>\n\n\n\n<p>These devices trick phones into diverting the connection that should occur with legitimate carrier towers. <\/p>\n\n\n\n<p><strong>Criminals<\/strong> use these fake networks to send <strong>scam text messages<\/strong>, exploiting older protocols, such as 2G, which have less <strong>protection<\/strong>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"como-funciona-a-fraude\">How Fraud Works<\/h2>\n\n\n\n<p>The method known as <strong>SMS Blasters<\/strong> involves exposing a fake 4G or 5G signal to downgrade victims&#039; connection. <\/p>\n\n\n\n<p>At the same time, a 2G network is activated to attract devices, taking advantage of the lack of <strong>mutual authentication<\/strong> of 2G. <\/p>\n\n\n\n<p>This allows attackers to intercept and decrypt connections, positioning themselves as a man-in-the-middle (Person in the Middle \u2013 PitM) to inject <strong>SMS payloads<\/strong>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"a-importancia-da-autenticacao-mutua\">The Importance of Mutual Authentication<\/h2>\n\n\n\n<p>THE <strong>mutual authentication<\/strong> is a security feature where the sender and recipient verify their identities. In the context of telephony, this verification occurs between the device and the operator&#039;s tower. The lack of this authentication in 2G makes it easier for attackers to act, allowing fraudulent messages to reach victims directly, bypassing the operators&#039; anti-fraud filters.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"ferramentas-nativas-no-android\">Native Tools on Android<\/h2>\n\n\n\n<p>Since the <strong>Android 12<\/strong>, released in 2021, users can disable 2G support. This option is already available on Pixel family devices, but has not yet been implemented by all manufacturers. In addition, <strong>Android 14<\/strong> introduced the option to disable null ciphers as key protection, essential to avoid connections to fake stations.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"protecao-adicional\">Additional Protection<\/h2>\n\n\n\n<p>In addition to disabling 2G, Android offers several other tools to protect devices against <strong>phishing<\/strong> and blows. The <strong>Google Play Protect<\/strong> is an example, reinforcing protection when browsing the internet and detecting phishing attacks and spam via text messages.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"concluso\">Conclusion<\/h3>\n\n\n\n<p>Disabling 2G on Android is an essential measure to <strong>protect<\/strong> users against SMS scams and phishing attacks. With the evolution of digital threats, it is crucial that users are aware of the security options available on their devices. In addition, exploring <strong>remote control apps for tv<\/strong> or <strong>apps to watch movies on your cell phone<\/strong> can offer more security and convenience in the daily use of technology.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"perguntas-frequentes\">Frequently Asked Questions<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"comodesativaro2gnoandroid\">How to disable 2G on Android?<\/h3>\n\n\n\n<p>Go to \u201cSettings\u201d &gt; \u201cNetwork &amp; Internet\u201d &gt; \u201cMobile network\u201d &gt; \u201cAdvanced\u201d &gt; Disable the \u201cAllow 2G\u201d option.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"oquephishingviasms\">What is SMS phishing?<\/h3>\n\n\n\n<p>Phishing is when someone sends you fake messages, pretending to be a trustworthy company, to steal your personal information.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"porquedesativar2gajudaaevitarfraudes\">Why does disabling 2G help prevent fraud?<\/h3>\n\n\n\n<p>2G has less security, allowing attackers to use fake networks to send fraudulent messages.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"todososcelularesandroidpodemdesativaro2g\">Can all Android phones disable 2G?<\/h3>\n\n\n\n<p>No. The feature is available from Android 12 and not all models already have this setting.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"oqueumaestaobasefalsafbs\">What is a Fake Base Station (FBS)?<\/h3>\n\n\n\n<p>It is a device used to create a fake mobile network, tricking cell phones into diverting their connections and sending fake messages.<\/p>\n\n\n\n<p><\/p>","protected":false},"excerpt":{"rendered":"<p>Disabling 2G on Android could be a powerful weapon against SMS fraud, Google has revealed.
