Your comp can be hacked using ur electricity power line or even toilet pipe!WTF***??

Till now we have heard that hackers use phishing methods or install
trojans into the victims computer to record keystrokes and steal
account informations. There are numerous programmes and methods advised
to prevent such kind of attacks, most common of them are anti virus
programes and firewalls. Even a laymen person new to the world of
internet knows the do's and dont's to keep himself secure. Thus it is
getting difficult for the hackers to come out with new methods to play
with the privacy of their victims as people are getting more concerned
about their privacy.

Two independent researchers Andrea Barisani(Alias lcars) and Daniele Bianco(Alias danbia) at inverse path

came out with a security loophole in your keyboard, preferably ps/2 and
laptop keyboard, that can enable a hacker to record your keystroke by
just connecting to your power grid, and yes, no anti virus program or
any firewall could detect this kind of sniffing. The fact that the
vulnerability is caused due to poor standards of wires used inside the
cables of your keyboard, even an advanced computer user is vulnerable
to such attack. All the hacker requires to do is to get access to your
power grid and there is nothing you can do to prevent it with the
current hardware availability. This work of Andrea and daniele is
greatly appreciated and their presentation is invited to PH-Neutral,
Shakacon, BlackHat and DEFCON.

Lets understand what exactly is

this all about. Current keyboards, specially ps/2 and those used inside
a laptop use relatively cheaper homemade hardware insulation around the
tiny wires inside the main cable connecting the keyboard and the
computer. This is absolutely fine as far as we consider that these
insulation are enough for proper functioning of the keyboard. A normal
ps/2 cable consist of 6 pins with four of them carrying data, Ground,
+5 V current and clock, respectively. As the wires are very close to
each other and not insulated well, they cause leakage of information
from the data wire to the ground wire due to electromagnetic coupling.
The ground wire as well as the other cable shieldings are routed to the
main power adapter ground which is then connected to the power socket
and finally
the electric grid of the area. This eventually leads to
keystrokes leakage to the electric grid which can then be detected on
the power plug itself, including nearby ones sharing the same electric
lines. Now the ps/2 keyboards use very low clock frequencies as
compared to other computer components. While most of the measurements
inside the CPU is done in Mhz, the clock frequency of ps/2 keyboards
lies in 10 - 16.7 kHz range. Also the keystrokes are recorded i-bit at
a time. This makes the data routed from keyboard easily separable from
other clock signals after an deep analysis of the data recieved. The
hack can be done easily with any physical contact to the ground of the
victim with a piece of metal, like a toilet pipe, or even having access
to the same power line within the same building. It is believed that
USB keyboards are not affected by this attack as they use differential
signaling for cancelling the noise.

  1. Yêu Huyên quát nhẹ, ngọc thủ giương lên, mũi xanh bạo liệt, mười sao Đấu Tôn lúc này cũng bị đánh thành mảnh nhỏ. Tên mười sao Đấu Tôn rất mạnh, nhưng so với Yêu Huyên miễn cưỡng có thể chống lại, nhưng sự xê xích quá lớn.

    Trong tay Yến Hiểu Kỳ cũng là một mảnh hỏa hệ ma pháp nóng bỏng bổ về phía một tên cửu tinh Đấu Tôn, tên cửu tinh Đấu Tôn kịp chạy ra năm trăm thước thì bị ngã trên mặt đất.

    Lúc này Hỏa Lão đánh ra Thiên Diễm Chi Hỏa bao vây về phía tên cửu tinh Đấu Tôn, chỉ chốc lát sau đánh chết tên cửu tinh Đấu Tôn này, Hỏa Lão có thực lực một sao Đấu Thánh đánh chết một tên cửu tinh Đấu Tôn là một vô cùng chuyện dễ dàng.

    trung tâm tiếng anhg một tên mười sao Đấu Tôn cũng bị Nhạc Thành chắn ở trước người, tên mười sao Đấu Tôn này sắc hoảng sợ, những tên này thấy có mấy Đấu Thánh xuất hiện, trong đầu hắn nghĩ có lẽ tứ đại Nhân Tộc bắt đầu đối phó Hắc Ám Thần Điện sao ác ngươi là ai, tại sao đối phó ta Hắc Ám Thần Điện.

    Tên mười sao Đấu Tôn sợ hãi nhìn Nhạc Thành hỏi, thân thể hơi hơi lui về phía sau.

Olive Nexus VR-9: Your handy Wi-Fi router

As modern netizens, getting online is probably a vital part of your day. Olive's Nexus VR-9 is a portable Wi-Fi router that makes it possible to share a single connection with all your Wi-Fi enabled gadgets. All you need is a high-speed USB data card.

The idea is simple: plug in a data card into the router's USB port and it instantly creates a Wi-Fi hotspot wherever you are. At home or in office, multiple laptops can share the same data connection. You could provide wireless internet for Wi-Fi phones, iPods and tablets. On the move, your laptop and portable gadget continue to have internet access as long as your battery lasts.

It comes with a wall charger to keep plugged in at home/office. On the move, the battery is good enough to power it for a respectable 3 hours and 50 minutes (at least two devices were connected throughout this time in our testing). Aside from the portability, the biggest advantage is the savings it can offer.
Priced at 3,500, the Olive Nexus VR-9 could e…

Kingston Launches HyperX Plug and Play RAM for Intel PCs

Kingston has released its new HyperX plug and play (PnP) series which is a collection of memory kits that utilize modules which are capable of working at frequencies of either 1,600 MHz or 1,866 MHz. This memory module is designed specifically for use with desktops and laptops powered by the latest generation of Intel Core i5 or Core i7 central processing units.

There are six kits in total, all of them composed of two kits, meaning that modules of 2 GB and 4 GB are used. There are two Dual in-line Memory Module (DIMM) kits, while the other four come in the Small Outline In-line Memory Module (SODIMM) form factor.

The modules are programmed using Joint Electron Devices Engineering Council (JEDEC) compliant settings, allowing 1600MHz and 1866MHz frequency support. It is as simple as plugging in the memory and turning on the machine, as the system automatically recognizes faster memory speed with no further basic input/output system (BIOS) settings required.
