On receiving an email about a lucrative moneymaking scheme, Sri Kumara registered as a member for free on the website www.legend-mails.com. The idea was simple—get paid to receive emails. To maximize his profits, within a month he upgraded himself to a diamond membership on the site by paying $269 (Rs. 12,110). After the payment, he got no response to his emails. He also never received any of the money promised by the site.

If you think you will never fall for a cyber trap like Kumara, think again. Seventy-six per cent of digital Indians have experienced some form of cyber crime, according to a Norton Cybercrime Report published last month. The world average is 65%.

Though viruses and malware top the list in online crime, such phishing emails are fast catching up. If you haven’t faced a virus threat, a password attack or a genuine-looking phishing email, count yourself lucky. But there is no harm in being prepared. Here are simple tips to browse securely.

Give out information only on secure sites

Any site which asks for your personal information (login ID, password, bank account details, credit card information), be it bank sites, shopping sites or email accounts, should have secure network indicators. First, check if the site has https written before its address. “Most websites are http only. An https site means it’s secure and encrypted,” says Ankit Fadia, an ethical hacker who works with the Union government on cyber crime, is the host of MTV What the Hack and has written 14 books on computer security.

An alternative symbol for a secure site is a small yellow padlock on the bottom left of your browser. Another one is when your URL bar goes green. “These symbols mean that other people in the same network cannot tie up into your communication or conversation. One of these pointers needs to be there before you enter any personal details online,” says Fadia.

“The most common mistake people make online is yielding to greed,” says G. Sivakumar, professor, department of computer science and engineering, IIT Bombay. “Expecting to win prizes, lotteries or receive handsome amounts of money, many users give away valuable personal information and also infect their computers with malware.” There are no free lunches, he stresses. If an email, especially by a stranger, makes an offer which is too good to be true, one should simply delete it.

Stay vigilant on your browser

Tab napping, a phishing scam, targets users who open lots of tabs on their browser at the same time. It replaces an inactive browser tab with a fake page set up specifically to obtain your personal data, such as a bank site. “You won’t even realize that it’s happening,” says Fadia. So if the bank site is open on a particular tab while you are working on another one, when you return to it, double-check before you enter the data. Malicious code can replace the Web page you opened with a fake version that looks virtually identical to the legitimate one. “Always retype a website address and then add your bank account or password to it,” he adds.

Also, almost all browsers support a private browsing mode. Make use of it. “This prevents storage of cookies and other personal information on the computer and makes it less vulnerable,” says Sivakumar.

Always cross-check bank emails with the bank

Especially if it’s asking for your account information or your I-pin. “A bank will never send out an email to ask for your account information,” says Vakul Sharma, a Supreme Court

advocate who has been dealing with cases of cyber crime. If you have any doubts, call up the bank and countercheck to see if they have sent out any emails. As a rule, be as stringent online as you would be in the real world. Would you provide your ATM pin to a person who comes knocking on your door and claims to be from the bank? Treat emails from the bank the same way. “Never input any sensitive information that might help provide access to your bank accounts, even if the link shows a page which appears legitimate,” warns Sharma.

Be alert when shopping online

Online shopping is one place where having multiple identities is recommended. “Use different IDs/email

addresses and passwords for various online activities,” suggests Sivakumar. Have a credit card meant only for online transactions. It should have a small credit limit so that in case someone else uses it, your losses are not too high.

Stick to a reputed website for shopping and use the virtual keyboard to enter details wherever you have the option. “Criminals use key loggers to record your passwords so a virtual keyboard is another level of protection,” says Fadia.

Opt for a secure password

“The most common reason for identity theft online is an easy-to-crack password,” says Sivakumar. According to him, a good password is a mix of uppercase and lowercase letters, numbers and one or more symbols such as !, @, # and ,.

Be smart about your smartphone

Did you know rice can save your phone? Here are some simple ways of keeping your smartphone up and running, without repeated visits to the service centre

A harried customer came to TVS E-Service Tech because the touch screen of her HTC Touch was not working properly. N.A.N. Natesh, a service engineer at TVS E-Service, a service provider for HTC smartphones in Bangalore, looked at the screen and said, “It was the case of months of abuse of the touch screen.” The customer had used her fingers, be they wet or dirty, to operate the touch screen, which was the cause of the problem.

“Smartphones are like children,” says Satchit Gayakwad, spokesperson, Research in Motion (RIM), the makers of BlackBerry. “You need to provide yours with lots of tender love and care.”

If you don’t understand how the device works, chances are you will not be able to make the most of it without making midnight calls to smirking service centre executives. Here are three ways to keep your phone in good condition and off the service centre table.

Battery bootcamp

“The most common complaint in a smartphone is battery draining and that the software OS (operating system) hangs,” says Natesh. In a month, Natesh and his team test 200-300 handsets. “Forty per cent out of these are in warranty and on our table for mishandling,” he says.

“Many people leave Bluetooth running even though they aren’t using it. Ditto with GPS, Wi-Fi and 3G,” says Atul Chitnis, a consulting technologist who is an expert in hand-held computing. These are power-hungry features and can eat up a significant amount of battery power over the course of the day. You should keep them disabled and use them only when you need to, like when you are transferring files or using the Net. “Also, don’t cover the antenna with your fingers. This causes the phone to work harder trying to maintain a signal, which causes faster battery drain,” he adds.

Backup plan: Maximize battery capacity.

Overcharging is another mistake. A smartphone charges in 1-3 hours. You need to take it out of the socket after that. “Never charge the phone overnight because that’s a sureshot way to kill your battery over the longer run,” says Natesh. Another battery killer is charging the phone before the battery is completely drained, he says.

When you browse the Internet on a smartphone, websites rich with multimedia such as flash animation and pictures consume more battery and make the download slower. You should simply set your browser option for text-only. Another common reason for battery leaks is constant updates of your email andsocial networking applications. “You need to know immediately you’ve got mail,” says Gayakwad, “but other than that, your social service networks don’t need to constantly search for updates.”

Third-party applications for social networking sites such as Twitter, Facebook, LinkedIn, MSN, Gmail and Gtalk constantly retrieve data from the Internet. These can be set to have refresh timelines of 20 minutes to an hour. This way, there’s no constant search for data by your phone on these sites and that can help save a lot of battery. Then there are applications such as weather updates which run in the background even when you’re not using them and can use up your battery life. Uninstall these apps. You can always reinstall them if you decide you need them at a later date. Applications such as complex games, flash-based applications which use up a lot of memory and CPU to play, also drain battery.

Safeguard sensibly

You need to use a cover and a screen protector for your phone. “If you use unclean or wet hands to use the touch panel of your phone, it will start giving problems, like not responding to your touch,” says Natesh. He advises the use of stylus on a touch screen. Regularly clean the exterior with a soft microfibre cloth to get the fingerprints off the screen and body. “Oh, and never vacuum the phone,” Gayakwad adds.

In case your mobile is exposed to water or falls into water, remove the battery immediately. “Never try to turn it on as that will short-circuit all its innards,” explains Gayakwad. Use tissue or cloth and delicately wipe off the moisture. “The easiest way of drying a phone is by putting it into a bowlful of uncooked rice. Rice absorbs moisture and makes the phone dry,” he adds. After it has dried, take it to the service centre. Service centres have special devices to dry your phone and make it functional again.

Smartphones are embedded with tiny, complicated electronic materials which are heat sensitive, so do not expose them to extreme heat, such as the dashboard of a car. “Heated phone also causes greater battery drain,” says Chitnis. So avoid extreme climates for your phone. In case it heats up, you need to give the phone battery some rest by switching it off for a while.
