Dexter(Shopping Trojan)-Beware While Shopping Through Debit/Credit Card

No comments:

Beware While Shopping Through Debit/Credit Card

The CERT-(Nodal department to protect Indian cyberspace and software base infrastructure against any destructive and hacking activities) responsible for Cyber-Security of India, has detected a Trojan in the online debit/credit card transactions on retailers counter.This Trojan name as “DEXTER”,which steals private information of debit/credit card while swiping card on shopping counters of retails stores.

This Trojan been detected while conducting its cryptic operation at the Pos(point Of Sale) on the shopping counters of retails shops.Now PIN is imperative as per RBI guideline's on each transaction after last December while purchasing through debit/credit card.

This Trojan work on “memory dump and grabber” while swiping on the infected machine,grabs  information of card and dump the memory after steal.Trojan acquire seven aliases once it's successfully breaching security protocols of PoS terminals,it steals the confidential data like card holder’s name,expiration date,CVV Code,account number and other transactional data from your card which leads to phishing attacks on your account later.

"The malware has routines to collect and parse personal sensitive information from the running processes in memory by enumerating the PoS related processes and has procedure to exfiltrate directly without interim storing in the hard disk," the advisory said.

"The common infection vectors for PoS system malwares includes phishing emails or social engineering techniques to deliver the malware, use of default or weak credentials, unauthorised access, open wireless networks along with the methods of installing malware as a part of service," 

    latest advisory issued to the public by the Computer Emergency Response Team (CERT-India)

Trojan is so potent and suspicious that after grabbing information through machine,it exits without any instance of its existence on the infected machine.

  “working in the said while customers should be vigilant about their debit and credit cards activities at sale counters swiping, PoS terminals should also firm up their defence mechanisms so that their systems are not compromised”.

                                                                                               senior official counter-cyber attacks department

The agency have given some instruction against the malware attacks

"Keep all PoS computers thoroughly updated including PoS application software, restrict access on PoS systems to PoS related activities only, ensure the networks where the PoS systems reside are properly segmented from non-payment network and restrictive policies on usage should be deployed and enforced,"

"maintain good security policy on the PoS computers (including physical access), disable autorun or autoplay, install and scan anti-malware engines and keep them up-to-date and exercise caution while visiting links within emails received from untrusted users or unexpectedly received from trusted users while also enabling firewall at desktop and gateway level."

                                                                                 the agency recommended.

As per the after the growth in the advance payment system these type of attacks is normal because now everyone wants step-up and want things must be ease for them in the tech scenario.Using above precautions retails store can maintain their security against Trojan.

The ‘smell-o-phone’: New device sends odours through smartphones

The ‘smell-o-phone’: New device sends odours through smartphones with special Accessories' :

What do you feel if your friend is in some part of world and enjoying some food or chocolate of different odours you think “I should be also their and experience its odour's”,is now possible.In the futuristic technology communication has put another footstep to communicate with smell.Students of Harvard University are researching a new way to communicate through smartphones with odours under the direction of researchers at Paris-based facility Le Laboratoire.This technology may as easy as sending text message.

"The Ophone will permit us to send olfactory messages instantaneously and around the world,"

                                                      Le Laboratoire states in its project outline.

"The Olfactive Project is a collaboration between artists, designers, scientists and performers built on an old dream of a universal language,"

                                                                                           David Edwards, founder of Le Laboratoire.

"The idea was not just to reproduce an existing way of communicating, but to create a new language.

"We wanted to find a way of diffusing smells accurately and coupling those smells with images. It was these two ideas that formed the basis for the Ophone".

"The device therefore not only makes it possible to accurately receive and share smells but also pair them with images on the screen of an Android device."

If O’phone alive then we are able to share images of different food with their odours of cultural spices with emotions and experiences with olfactory sentences,paragraph and even essays with odours.

Scientists Have Observe First Nature Ball Lightning

No comments:

ku-xlarge

Ball lightening is the first introduced as St. Elmo’s Fire.Scientist have earlier created this ball in lab but never observe naturally,phenomenon create a moving, glowing sphere that hangs in the sky.

In the Qinghai region of China,scientist's were observing a thunderstorm in 2012 using video cameras and a spectrometer, a device that measures light and electromagnetic waves to identify elements.This sphere recorded recorded a five-meter-wide flash of ball lightning that stayed in the air for about 1.6 seconds.

Theory:

when lightning strikes the ground, it blasts a cloud of highly-energized soil nanoparticles into the air. As those energized particles calm down, they emit light.

the researchers analysed the spectrometer readings to find large indicators of silicon, iron and calcium, elements present in the soil of the region.

In the world technology all the expectations are now becoming real and the new fore step is in the way to connect the internet with the LED bulbs.According Chinese Scientists,technology of Wi-Fi will serve in the form of Li-Fi with the 1 watt LED bulb.

This micro chipped bulb can produce data speed of up to 150 Megabits per second (Mbps)

                                                                  Chi Nan, IT professor at Shanghai's Fudan University

According to scientists,1 watt LED light bulb light energy is sufficient for connectivity to four computer.There is no evidence or supporting videos for demonstrating.Li-Fi technology is also known as visible light communications (VLC),if this possible then connectivity invade in the new generation and all other fiber optics and cables may flashed not even this can give up more internet speed from conventional Chinese broadband connection.VLC technology will compensate all high cost which are burden for the netizens of China.

Professor Haas showing off his li-fi system

In 2011, Prof Harald Haas, an expert in optical wireless communications at the University of Edinburgh, demonstrated how an LED bulb equipped with signal processing technology could stream a high-definition video to a computer.

"We're just as surprised as everyone else by this announcement,"

"But how valid this is we don't know without seeing more evidence. We remain skeptical."

                                                               Nikola Serafimovski PureVLC spokesman .

Future:

Li-Fi is very cheap and efficient technology,possibilities are dynamic. In the laboratory condition data transfer may be 1 1Gbit/s per LED light frequency with  RGB LED claimed by Fraunhofer Heinrich Hertz Institute.LED visible light have 10,000 bigger electromagnetic spectrum then radio system.

She admitted that the technology was still in its infancy and needed further developments in microchip design and optical communication controls before it could go mass market.

Prof Chi's research team Shanghai Institute of  Technical Physics at the Chinese Academy of Sciences,

Possibilities:

Due to the Light Emitting possibilities of signal lost or propagation ratio became negligible and get the cen percent data without any interruption.Hacking of wireless network will quite difficult which is beneficial for security and data loss,but this may be also major drawback that if light block then your signal will also lost.

This be the great step in the connect and there is very vast future for this technology due to insufficient evidence and lack of information,quite difficult how will this work and how implemented
