Pinhole Cameras in Changing Rooms of Big Bazaar, Shoppers Stop?

A few days ago, I received this text message:
Please don't use Trial room of BIG BAZAAR there are pinhole cameras to make MMS of young girls.
So, please forward to all girls. Also forward to all boys who have sisters and girlfriends.

Don't be shy in forwarding this message. Because its about protecting the integrity of all girls & ladies.

HOW TO DETECT A 2-WAY MIRROR?

When we visit toilets, bathrooms, hotel rooms, changing rooms, etc., How many of you know for sure that the seemingly ordinary mirror hanging on the wall is a real mirror, or actually a 2-way mirror I.e., they can see you, but you can't see them. There have been many cases of people installing 2-way mirrors in female changing rooms or bathroom or bedrooms.

It is very difficult to positively identify the surface by just looking at it. So, how do we determine with any amount of certainty what type of Mirror we are looking at?

CONDUCT THIS SIMPLE TEST:

Place the tip of your fingernail against the reflective surface and if there is a GAP between your fingernail and the image of the nail, then it is a GENUINE mirror.

However, if your fingernail DIRECTLY TOUCHES the image of your nail, then BEWARE, IT IS A 2-WAY MIRROR! (There may be someone seeing you from the other side). So remember, every time you see a mirror, do the "fingernail test." It doesn't cost you anything. It is simple to do.

This is a really good thing to do. The reason there is a gap on a real mirror, is because the silver is on the back of the mirror UNDER the glass.

Whereas with a two-way mirror, the silver is on the surface. Keep it in mind! Make sure and check every time you enter in hotel rooms.

Share this with your sisters, wife, daughters, friends, colleagues, etc

How to safeguard your Bank ATM card from fraudsters?


Like the news on street-side robbery, house-breaking, bank robbery etc we are used to read in the news papers few years ago, nowadays we come across lot of news on debit card (also popularly called as ATM card) frauds.
Innocent people, especially salaried class are victims in these frauds as they expose their debit cards more in the ATM to take out their salary credited in the bank.
We provide here a news published in Hindu recently on one kind of these ATM Card fraud in which fraudsters were held by police in Chennai.
A gang that robbed 64 persons in chennai of over Rs.30 lakh last month after making fake bank cards has been busted by police.
The gang members used a slim skimmer device that they placed inside the card slots of four ATMs, in different locations, to obtain details of the victim's card details, including the PIN.


Police launched investigations after Commissioner of Police receivedcomplaints from 64 persons last month stating that someone had drawn large sums of money from their bank accounts.
When the victims made enquiries with their banks, the officials told them that the money had been drawn using ATM cards.
It was found that the money was drawn from four ATMs – in West Mambalam, Kilpauk, Kotturpuram and Saidapet.
“The gang opted for the four ATMs because these facilities had neither a security guard nor a CCTV camera. We gathered information about the movement of people who visited the kiosks and details of calls made and received on mobile phones of those who came to the ATMs. During the cell phone trace, our team zeroed in on a mobile phone number, which was used at all the four ATMs,” the police said.
Fraudsters confessed to having inserted film-thin skimmer devices made in China, worth $ 2,000 each in the card slots of the four ATMs. The devices with a two-day battery life are capable of capturing card details, including the PIN, through an advanced sensor panel when a customer uses the card issued by the bank. They replaced the skimmer devices every two days and used the information to make fake cards.
Advanced skimmer devices with sensors can detect the movement of fingers on the numeric pad on the ATM.
Earlier, a pinhole camera on the skimmer placed inside the card slot was used by culprits to read the PIN number. Now the fraudsters have gone one step ahead.
The police have advised ATM users to inspect card slots for any suspicious objects and change PIN numbers of their bank cards at frequent intervals.

We also provide a slide show below issued in the interest of people by Common Wealth Bank.
This slide-show shows the possible area where skimmer device is installed by fraudsters in the ATM.
·         Though it may not be fully possible all the time by a layman to identify the illegal installation of a skimmer device in the ATM, a cautious look at the card insertion area of ATM may throw some light.
·         Even if you just suspect that the ATM is tampered with, you can go to a nearby ATM where security people are available all the time.
·         You can also avoid loss of your debit card information by frequently changing your ATM password.
·         Safest of all of these precautionary measure is not to expose your debit card linked to your main account in which you receive your salary and other payments in the ATM unless it's an emergency. Then how can we withdraw amount for our day to day expenses?  Here we have an easy solution.
·         If you have internet banking facility for your main account, then you can easily safeguard your money. You have to open another account in another bank with ATM card facility and transfer small portion of amount to this alternative account from the main account usinginternet banking. Now the ATM card of the alternative bank account can be exposed in the ATM, while you never take outside the ATM card of the main account unless it's an emergency. Whenever, the alternative bank account balance is nil you can use internet banking within no time to transfer amount to the alternative account from the main account.

Keeping your Gmail Account Safe


At Google, we take account security very seriously. To ensure that your computer and account remain safe, we strongly recommend following these steps regularly:
  1. Check for viruses and malware. Run a scan on your computer with a trusted anti-virus software. If the scan detects any suspicious programs or applications, remove them immediately.
  2. Regularly update your account recovery options. Make sure to update your account recovery options to check that they are always up-to-date.
  3. Change your password at least twice a year. Make sure you choose a password that contains a combination of numbers, characters, and case-sensitive letters to strengthen the security of your account. 
  4. Enroll in 2-step verification. 2-step verification adds an extra layer of security to your account by requiring you to sign in with something you know (your password) and something you have (a code sent to your phone).
  5. Perform regular operating system and browser updates. Whether you use Windowsor Mac OS, we recommend enabling your automatic update setting, and updating when you get a notification. To check for browser updates in Internet Explorer, select the Toolstab and click Windows Update. In Firefox, just click the Help tab and select Check for Updates. Note that Google Chrome automatically updates to a newer version when one is released.
  6. Never use your Google Account password on another website. If you enter your password in an external website and it's compromised, someone could try to sign in to your Google Account with the same information.
  7. Protect your password. Never enter your password after following a link in an email from an untrusted site. Always go directly to mail.google.com orwww.google.com/accounts/Login. Also, never send your password via email. Google will never email you to ask for your password or other sensitive information.
If you use Gmail:
  • Update your recovery email address and your security question. This will help you recover your account if you ever lose access to it. Make sure that you have access to the email address listed as your recovery, and the answer to your security question is easy for you to remember, but hard for others to guess. 
  • Use a secure connection when signing in. In your Gmail settings, select 'Always use HTTPS.' This setting protects your information from being stolen when you're signing in to Gmail on a public wireless network, like at a cafe or hotel. 
You should also be sure to:
  • Never tell anyone your password; if you do tell someone, change it as soon as possible.
  • Use a strong password, and don't write it down or send it via email.
  • Run scans and change your password immediately after noticing any changes in your account that you didn't initiate.
  • Always sign out of your account when you're using public computers. Just click Sign outin the top right corner of the screen when you're done using your Google Account.
  • Clear forms, passwords, cache, and cookies in your browser on a regular basis, especially on a public computer.
You should perform these steps more frequently if you begin to notice suspicious behavior in your computer, such as general slowness and pop-up advertisements. For more information on keeping your account secure, check out Google's Safety Center.

If you believe that your account has been compromised, please reset your password immediately.

How to easily stay secure online? Simple and easy tips!

Every single time you connect online did you know that you face dangerous Computer security hazards. Viruses, Trojans, Root-Kits, hackers, and junk e-mail await you at every turn. The truth is that these menaces are forever going to comprise a constituent of being connected and also doing business online.

There are a number of safeguards you will be able to take to make yourself and your computer systems safe.

I will now list out to you the best proven tactics to enhance your Internet security whenever you are online:

Virus Protection. Make certain you've the up-to-the-minute virus updates installed on your system and allow the software to exhaustively scan your entire computer every day to guarantee that no computer virus are successfully embedded themselves on your disk drive. Use a modern anti-virus like VIPRE Antivirus Software to scan both your computer and your email. AVG, McAfee and Norton likewise offer similar products.

VIPRE used to initially produce CounterSpy which was a leading spyware and malware protection software online from many years.

Spam Blocker. I've a junk e-mail blocking agent that I use with Microsoft Outlook called Cloudmark Desktop that fares a excellent task of assisting my Microsoft Outlook to distinguish junk e-mail.

Use a Alias E-mail address : For instance, whenever I'm signing up for a free technology mailing list / product news, I might use something like jasonblr+technology@gmail.com, which will then end up with a special label in my gmail Inbox. Therein, you do not have to divulge your "real" e-mail address, and you will be able to ascertain whenever the list holder trades or leases your e-mail address to another. Therefore, if you all of a sudden start to get emails to your jasonblr+technology@gmail.com e-mail address from a hard disk maker you have never heard of, you'll know that the technology mailing list folks traded or leased your e-mail address to others.

Firewalls: Always make certain that you are using a firewall protection. At a lower limit, to protect your computer from being hacked while you're online you can use Windows Firewall. Or, use a free firewall like COMODO. Whenever you use a wireless router, make sure to configure a password to secure it so that anyone going past your residence or office can't hijack your signal and possibly hack your computer network. I was readjusting the wireless connection on my laptop last night and came across several unsecured wireless connections in my vicinity. I reside in a residential area without any business organizations, thus I cognize that these represented insecure wireless routers in my neighbors' residences.

Be safe and enjoy the internet super highway.

Guidance for Using a Laptop Computer


Laptop computers are not ideal for continuous use. They normally have an elevated and compressed keyboard, a small display screen that is at an angle and position not ergonomically sound, even if they are at an otherwise entirely suitable workstation.

Incorrect or inappropriate use of laptop computers can cause health problems. This guidance offers some practical advice on how to avoid any problems.
Occupational Health has put this leaflet together as an additional aid for anyone who uses a laptop and it should be noted that general workstation set up etc. is covered in the guidance and code of practice documents for computer use.

The significant hazards associated with laptop use may include:

Ergonomics of use – the requirements for portability often means that the ergonomic standards developed for desktop computer workstations are largely ignored when an individual uses a laptop. Often laptops are used on laboratory benches, unsuitable desks and tables at home, on trains or in hotel rooms with limited legroom, poor seating and incorrect screen positions. There are therefore foreseeable risks of developing a wide range of health problems from such poor ergonomic environments.
Vision fatigue – often laptops are used extensively in environments, which do not have suitable lighting. Additionally, laptops often have screens that are not as clear, stable or as bright as normal computer monitors. It is possible that users may be exposed to a greater risk of developing temporary vision fatigue as a consequence.
Manual handling – laptops and their accessories are typically in excess of 5 kg. Although well within the ‘accepted normal load’, they may need to be carried in addition to other items for long periods of time when travelling.
Theft – There is also a real risk of theft and steps should be taken to avoid personal injury by being cautious whilst commuting with equipment. Brand name cases should not be used if possible as this draws attention to the value of the equipment that is being carried.

The following tips should help ensure that you can work comfortably and safely with your portable computer.

Purchasing:

Tip 1: Test the keyboard before purchase to make sure it fits your fingers - miniature keyboards are fine only if you have small fingers or do little data entry/word processing. If you must have a small keyboard and still want to type comfortably, consider fewer keys (with multiple shifts) or use a separate keyboard for such work.
Tip 2: Purchase laptops that have the largest and brightest screen you can afford. It is easier to create a more ergonomic position with such screens and they minimise the potential for vision fatigue. The angle of the screen should be approximately 90o to you line of vision to view the screen clearly.
Tip 3: If possible, buy a ‘docking station’ or attach a separate monitor and/or keyboard to a portable computer for prolonged use since the screen will inevitably be below the optimum viewing angle for comfort.
Tip 4: If you intend to work whilst travelling, make sure the pointing device (trackball, button or whatever) can cope with movement and vibration. Palm or wrist rests in front of the keyboard can help provide a stable base for use on the move, or in the office environment.

Health:

Tip 5: When using a trackball or glide pad, keep your hand relaxed with your fingers moving together. Do not screw up your fingers or hold them up in the air while working.
Tip 6: You dramatically increase strain if you twist your body or try to operate your laptop within a cramped environment, such as while travelling. Ensure comfortable working. Adjust your seat to support your back and place the laptop on a flat surface at the correct distance and angle from you.
Tip 7: If travelling, check the total weight you will need to carry. Although laptops are getting lighter, most still require external mains transformers and power leads etc. Additionally most people will also have to carry other papers, their briefcase and other articles. This can result in a number of musculoskeletal disorders over a period of time. The normal solution is a shoulder bag with a padded shoulder strap. Additionally, you can reduce the weight carried by ensuring the battery is fully charged so as to avoid carrying a spare battery.
Tip 8:  You may wish to consider purchasing a lightweight laptop stand, mouse and compact keyboard.

When Blind copy of email is always safe?


We will always want to share interesting Emails with our friends. We successfully complete this mission by just clicking the forward button in our E-mail interface and filling up email addresses of our friends in the "To" address box or "CC" address box.
This method would serve the purpose. But is it a safe way for forwarding emails?
For any novice internet user this method may be sounding good. But basically it is a not safe way of forwarding mails.

 

Significance of TO, CC and BCC:

The "To" address box is of course the text field where you have to enter the email address to which you want the mail to be sent. Multiple email addresses can be entered in this field for one to many delivery.

CC:

The "CC" stands for the term Carbon Copy. This is similar to writing a letter to somebody and mark a copy of the same to others.

When to use CC:

We have to note here that the recipients who are the owners of email addresses you entered in the TO address box as well as "CC" address will come to know about the other recipients to whom the email was sent. So you have to use "CC" address box prudently in the cases where you should ensure that all recipients should know the email details of other recipients to whom the mail is sent. To put is simply, the email message received by the recipients whose email addresses are entered in the "CC" address box will contain the email address of the sender as well as the email addresses of other recipients.

BCC:

The "BCC" stands for Blind Carbon Copy. If you enter the email address of the recipient/recipients here, they will not come know about other recipients to whom this mail was sent, the ultimate email message would contain only the sender's email and other contents of the email. The email addresses of other recipients will not be figuring in the mail.

When to use BCC:

While you are in compulsion that the recipients should know the email addresses of the other recipients you have to use CC. In all other situations it is better to use BCC because it's safe way of handling email harvesters

What is email harvesting:

It refers to manual or automated way of collecting email addresses by bulk email senders for sending spam (unwanted/unsolicited emails to advertise/propagate something-especially illicit products, obscene contents etc), virus programs to harm the computers.
Email harvesters normally tend to make automated programs to harvest mail addresses from the web.
But for an email harvester, receipt of mails that are sent using CC address boxes will be like giving bank locker keys to a robber.
A typical email received by a recipient whose email address was entered by sender in the CC address box:
From: abc@gmail.com
To: bcd@gmail.com
CC: 123@yahoo.co.in, 234@gmail.com, 456@yahoo.com, 765@yahoo.com, xyz@rediff.com
I find this mail very interesting and thought of forwarding this to you……….
It will be a cake walk as he will add more email addresses to his kitty without any difficulty so that he can send spam to more persons and harm more computers.
But when BCC address box used the recipient will receive only the sender's email address apart from the content.
A typical email received by BCC recipient:
From: abc@gmail.com
To: bcd@gmail.com

I find this mail very interesting and thought of forwarding this to you……….
So, if we use TO CC and BCC address boxes prudently by understanding the functional difference between them, it  will be great help that we do to our friends and their friends by safeguarding them from spam, virus threat etc.
