Everyone and their mother has a smartphone these days, but to most, security isn't even a thought in the forefront of their minds. It would be great that if every time your mobile device was hacked, you would be notified with a message on your screen. Since that isn't a thing (for now), here are a few indicators that can help you recognize if your smartphone has been hacked, and if you notice more than one of these signs occurring simultaneously, there's a good chance your smartphone has been compromised.
A first sign is that websites will often appear differently. Sometimes this can be due to a change in a company's branding, giving them a refreshed look. However if a website looks one way, then appears to be different after clicking a link, there's a good chance that link is giving a hacker access to your mobile device.
Next, look for the presence of mysterious apps. It's one thing to have a child or significant other download random apps on your phone without permission, but if an app finds it's way onto your device without you or anyone you know installing it, that's another sign someone has gained access to your mobile device and can acquire more personal information than you think.
Another sign is rapidly decreasing battery life. This sign is a little tricky because smartphone batteries are constantly being drained from apps running in the background, but if you have been hacked it's most likely an app you hadn't opened previously. In relation to a rapidly decreasing battery life, the phone itself will be hot to the touch. Think of your battery working overtime to support the data you're transferring as well as all of the data being leaked from your device, of course it's going to be a little over-worked.
One more sign is an increase in blacklisted network traffic. Look for is a lot of traffic going to a blacklisted IP address. While it doesn't happen often, this is the best way to detect if your smartphone is being hacked if you're not using mobile security software.
Last, but definitely not least, be on the lookout for sensitive data leaks. If you notice major information has somehow leaked outside of your company, and are unsure why, there's a good chance your mobile device has been hacked.
Before blaming all data leaks on a computer hack, you should also keep in mind that a mobile device could have been compromised instead. Think of how many of us use our mobile devices to check our work and personal emails, in addition to some of the websites we visit have unblocked pop-ups. While smartphones are an increasingly common threat to data security, don't let a breach go undetected by focusing solely on computers.
