&lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;signal.org&amp;#x2F;blog&amp;#x2F;whatsapp-complete&amp;#x2F;&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;signal.org&amp;#x2F;blog&amp;#x2F;whatsapp-complete&amp;#x2F;&lt;/a&gt;&lt;p&gt;But of course, in this case the issue seems to be either compromise of the device(s) via zero days, whatsapp usage simply being the target matrix - and&amp;#x2F;or a leveraging a zero day in whatsapp for full device compromise.&lt;p&gt;It&amp;#x27;s unlikely signal would be immune - they didn&amp;#x27;t Crack the encryption, they cracked the app&amp;#x2F;os.&lt;p&gt;In olden times the vector might have been a font, or a gif.&lt;p&gt;The only advantage signal has is a conservative interface and small userbase. I&amp;#x27;m not sure if they do some kind of hard-line whitelisting of attachments though - if you can pack an exploit as a file, I&amp;#x27;m pretty sure you could send it via signal.</text><parent_chain><item><author>vocatus_gate</author><text>A buddy of mine is Special Forces (U.S.).
