The holiday season is here -- and you may be travelling in India or abroad. But be careful when you surf the Net
May 1 2018: The biggest concern for tourists on holiday these days is WiFi . Will they be able to access the Internet where ever they go? Many hotel rooms and lobbies, airport departure and arrival halls, coffee shops and restaurants, offer free WiFi -- sometimes you have to obtain a password . This may be OK for a quick mail check -- but many wonder : Can I do financial transactions -- rebook a ticket say? Short answer: don't. Today hackers lurk in such public places with sophisticated tools.
There was a chilling report from a Dutch magazine recently reported by Medium.com, about a hacker in a cafe with a small black device, slightly larger than a pack of cigarettes, with an antenna on it. This was all he needed to hack into every single phone or laptop that was being used in the cafe.
It is sensible to always switch to a VPN or Virtual Private Network when surfing public WiFi. VPNs make you invisible and act as a secure tunnel for your device. Instead of relaying all of your traffic to an unknown router on public WiFi, your device connects to a trusted VPN provider. Check if your browser provides the option of switching to VPN. If not--at least for your holiday -- use a browser like Opera Mini which comes with VPN. Or install a VPN tool like Norton WiFi Privacy.
The best solution is to buy an unlimited data plan for your device and stop using public Wi-Fi altogether. When abroad, buy a local SIM for your mobile phone, with a good data plan for broadband -- and do your online commerce in the privacy of your hotel room, using your own SIM.
