WhatsApp chats are more than just simple texts. We all know it. We share photos, videos, bank account details, contacts and what not on WhatsApp. And with so much personal data, if you take privacy and security of WhatsApp for granted then its jackpot for wicked minds.
ESET advices WhatsApp users by providing top security tips to stay secure on their personal chats. WhatsApp recently announced that it has more than 700 million monthly active members, sending a combined total of 30 billion messages a month. That’s an enormous volume of personal information being communicated, and even though WhatsApp now encrypts all of its messages and data, it pays to be secure with your chats. Here are eight top WhatsApp security tips
On iPhone, it’s easy to fix: Go into your phone’s Settings menu, then ‘Privacy’, ‘Photos’, and deselect WhatsApp from the list of apps whose images are fed into the photostream.
Android users will have to get under the hood a little bit. Using a file explorer app like ES File Explorer, find WhatsApp’s ‘Images’ and ‘Videos’ folders. Create a file within each called ‘.nomedia’. That will stop Android’s Gallery from scanning the folder.
Secondly, if you exclude WhatsApp images from your photoroll, and lock the app as above, it provides another layer of security if your phone is stolen or hacked into – but it won’t be a 100% bulletproof solution.
2) Lock WhatsApp
One of the best WhatsApp security tips is to protect the app with a password or PIN. WhatsApp itself doesn’t offer such a function, but there are third-party apps that do. It might seem cumbersome but if you lose your phone, it’s going to prevent anyone else accessing your chats. Messenger and Chat Lock, Lock for WhatsApp and Secure Chat are three Android apps that do just that.
3) Restrict access to profile picture
Is your profile photo one you’ve used elsewhere – on LinkedIn, Facebook or Twitter? Maybe it’s even on your company’s website somewhere. If it is, and your WhatsApp sharing is public, anyone you’ve ever spoken to – even if you’ve just replied to an unwanted message – can download your pic from your WhatsApp profile and, using Google Image search, very quickly find out more about you. Set profile picture sharing to “contacts only” in the Privacy menu.
4) Hide ‘last seen’ timestamp
Not sure you want people to know when you’re coming on and offline? It may not seem like vital information, but if a scammer already knows some other things about you, adding that last piece of contextual information could prove useful to them – whether you’re awake or not; at home or overseas; coming out of the cinema or getting off a flight. Or you just might not want contacts – especially colleagues, or your boss – to know you’re checking WhatsApp at your desk. You can disable or restrict who sees your ‘last seen’ time in WhatsApp’s ‘Profile’; ‘Privacy’ menu, in Android, iOS, Windows or Blackberry. Be aware though, if you turn it off, you won’t be able to see other users’ ‘last seen’ times either.
5) Be careful what you talk about
Last but not least, use the same common sense you would with any form of digital communication. Don’t send personal information if you can possibly avoid it – addresses, phone numbers, email addresses – and never send your bank, social security or credit card details, or your passport or other identification details.
6) Watch out for scams
WhatsApp itself will never contact you through the app. Also, WhatsApp does not send emails about chats, voice messages, payment, changes, photos, or videos, unless you email their help and support to begin with. Anything offering a free subscription, claiming to be from WhatsApp or encouraging you to follow links in order to safeguard your account is definitely a scam and not to be trusted.
7) Deactivate WhatsApp if you lose your phone
WhatsApp offers users simple and effective security tips to keep control of your account if your phone is lost or stolen. As well as locking your SIM card through your network provider, WhatsApp recommends that you immediately activate WhatsApp with the same phone number on a different phone, with a replacement SIM. The app can only be used by one number on one device at a time, so by doing so you instantly block it from being used on your old phone. If that’s not possible, WhatsApp can deactivate your account.
8) Remember to log out of WhatsApp Web
WhatsApp recently made a lot of noise with the launch of WhatsApp Web. The mirroring service makes life easier while working on PC. However, most users are unware that they should ideally log out of WhatsApp Web on Google Chrome browser either from their mobile or the browser. Just imagine your collegues reading your chats on a large screen while you stepped out for a coffee break.
