The terrorist groups are encouraging its followers to use Telegram<\/span><\/strong><\/a> to make their propaganda invisible from law enforcement, but some security experts believe that Telegram may not be as secure as jihadi advocates may like to believe.<\/div>\n
<\/div>\n
Telegram is an end-to-end encrypted messaging<\/span><\/strong><\/a> service that has been adopted by a lot more people than ISIS \u2014 as of last year, the company claimed more than 50 Million Telegram users sending 1 Billion messages per day.<\/div>\n

Terrorists love Telegram<\/span><\/strong><\/a> because it not only provides an encrypted Secret Chat<\/b> feature that lets its users broadcast messages to unlimited subscribers but also offers self-destructing message<\/b> allowing users to set their messages to self-destruct itself after a certain period.<\/p>\n

Is Telegram Really Secure?<\/b><\/h3>\n
<\/div>\n
In a blog post published Wednesday, the security researcher known as “the Grugq<\/b>” pointed out several issues with Telegram<\/span><\/strong><\/a> that might obstruct terrorists from using it.<\/div>\n
<\/div>\n
Here’s the list of issues with Telegram:<\/div>\n
<\/div>\n

1. Error prone<\/h4>\n
Telegram’s end-to-end encrypted chat feature is not enabled by default. One has to select Secret Chat before start chatting, and it is not possible to encrypt an existing conversation.<\/div>\n

2. Contact Theft<\/h4>\n
Telegram requires you to register a working phone number and uploads the entire Contacts database to its servers, helping it create a trail of breadcrumbs for law enforcement and investigators to follow.<\/div>\n
\n

“This allows Telegram to build a huge social network map of all its users and how they know each other<\/i>,” the Grugq wrote in his blog post.<\/p><\/blockquote>\n<\/div>\n

<\/div>\n

3. Leak Voluminous Metadata<\/h4>\n
The use of a mobile phone can expose a wide range of metadata. Even if secure chat is enabled, law enforcement can collect other Metadata for sure by compromising the servers.<\/div>\n
<\/div>\n
This could help them track down who talked to whom, at what time, from which location, which will be an enough information for agencies seeking for possible suspects.<\/div>\n
<\/div>\n
For Example:<\/b> If A and B are communicating with each other on encrypted channel, and A is on the suspect list of agencies, then they can at least figure out the connection between both using this Metadata.<\/div>\n

4. Wonky Homebrew Encryption<\/h4>\n
Some security experts are also worried about the encryption that Telegram uses, although its encryption hasn’t been publicly broken.<\/div>\n
<\/div>\n
Telegram has announced<\/span><\/strong><\/a> a contest to crack the app’s encryption with a prize money of $300,000, but nobody claimed it.<\/div>\n
<\/div>\n
However, when it comes to nation-state adversary, one wouldn’t trust encryption protection in Telegram, as the app might work for the average user, but is not secure enough for terrorists.<\/div>\n
<\/div>\n
Whatever be the privacy concerns regarding Telegram, the good news is:<\/div>\n
<\/div>\n
Telegram has blocked 78 ISIS-affiliated Channels<\/span><\/strong><\/a> that the terrorist used to communicate with their members, spread propaganda and plan operations.<\/div>\n
