Question

Can your phone be hacked by just the phone number?

Dec 20, 2014 2:51PM PST

I'm kind of worried that my phone may have been hacked. I recently started working at a new job, and there is another spanish man that works there that seems kind of creepy. He's been asking me general questions over the past few weeks, name, birthday, where I live, and other stuff like that, so he has SOME general knowledge about me. Today he asked if he could have my cell phone number, and I didn't think much of it at the time, so I gave it to him. Not even an hour later, I opened my Galaxy S5 phone, and there was a text message up - that I had not even seen or read previously - that was open, and where I would type my message, it showed that I had typed "hahaha gracias". This would not be something that I would have ever typed, and I know that I had not. There were also other messages that showed that they had been read, but I had never opened them myself. I'm just a little spooked now and am wondering if this man would have been able to somehow hack my phone, even with just my phone number, my name, and some of my general information.
Thank you :/

....unless they got your phone and was able to install some malicious application. If they were able to log-in to your Google account, they may have been able to read your messages. I don't have a definitive answer for you.

Anything is possible

I found this article which was published in 2009. The article stated "CSO recently sat down with Trust Digital, a firm that specializes in mobile security, for a demonstration on how to hack a smartphone with no more information than a phone number."

http://www.csoonline.com/article/2112407/identity-access/3-simple-steps-to-hack-a-smartphone--includes-video-.html

If that was possible in 2009, imagine how much easier it could be for people to hack into other phones with just a phone number now. Not saying that this is possible for everyone to access but its just a possibility that it can happen.

Phones are pre-hacked.

Google up CIQ on Android and frankly, your phone is not yours at all. Scary.
