Πιστωτικές κάρτες με κενά… ασφαλείας

Φεβρουαρίου 12, 2010

Δεν είναι πρόσφατη η αποκάλυψη ότι οι νέες πιστωτικές κάρτες με ενσωματωμένο chip, έχουν προβλήματα.

Συγκεκριμένα από τον Αύγουστο του 2008, σε ποστ του ο Steven Murdoch αποκάλυψε τα κενά ασφαλείας χωρίς όμως τελικά να πάρει δημοσιότητα το θέμα και να βρεθούν λύσεις. Απόδειξη για την μη κάλυψη των προβλημάτων αποτελεί το paper των Steven Murdoch, Saar Drimer, Mike Bond, και Ross Anderson και το ποστ του τελευταίου όπου εξηγείται αναλυτικά το πρόβλημα.

Ενδεικτικά οι ερευνητές του Computer Laboratory, University of Cambridge, αναφέρουν στο δελτίο τύπου τους ότι:

Cambridge researchers show that the Chip and PIN system is vulnerable to fraud

Thursday, 11 February 2010

Steven J. Murdoch, Saar Drimer, Ross Anderson and Mike Bond, researchers at the Computer Laboratory, University of Cambridge, have shown that flaws in the Chip and PIN system allow criminals to use stolen credit and debit cards, without knowing the correct PIN.

Fraudsters can easily insert a “wedge” between the stolen card and terminal, which tricks the terminal into believing that the PIN was correctly verified. In fact, the fraudster can enter any PIN, and the transaction will be accepted.

Murdoch says, “We have tested this attack against cards issued by most major UK banks. All have been found to be vulnerable.”

Victims of this attack may have a difficult time being refunded by their bank. The receipt produced will state “Verified by PIN”, and bank records will show that the correct PIN was used. Banks may then argue that the customer must have been negligent and had allowed the criminal to know their PIN.

Drimer says, “The technical sophistication for carrying out this attack is low, and the compact equipment will not be noticed by shop staff. A single criminal can develop and industrialize a kit to be used by others who do not need to understand how the attack works.”

The Cambridge attacks call into question both the design of the Chip and PIN system, and the security of card payments. Victims of fraud are commonly told that bank systems can be relied upon. However, this attack shows that criminals are able to not only defraud customers, but cause bank systems to make the false assertion that the PIN was verified correctly.

Anderson said «Over the past five years, thousands of cardholders have had stolen chip and pin cards used by criminals. The banks often tell customers that their pin was used and so it’s their fault. Yet we’ve shown that it’s easy to use a card without knowing the pin – and the receipt will say the transaction was ‘verified by pin’ even though it wasn’t.»

Anderson continued «This is not just a failure of bank technology. It’s a failure of bank regulation. The ombudsman supported the banks and the regulators have refused to do anything. They were just too eager to believe the banks.»

The attack will be featured on Newsnight, including a demonstration of it being deployed in practice. Watch BBC Two, 10:30pm, Thursday 11 February 2010.

The Cambridge team’s results are also to be presented at the the academic conference “IEEE Symposium on Security and Privacy”, Oakland, CA, US, May 2010.

Ελπίζω ότι στην χώρα μας έχουμε πάρει τα σωστά μέτρα και ότι σύντομα θα ενημερωθούμε για τις λύσεις και βέβαια για τον τρόπο προστασίας μας από τις αδυναμίες στην ασφάλεια των νέων πιστωτικών καρτών που κυκλοφορούν σε εκατομμύρια στην Ευρώπη.

Η ΝΙΚΟΝ χθές ανακοίνωσε μια σειρά από compact ψηφιακές μηχανές με διάφορα χαρακτηριστικά.

Εγώ διάλεξα την αγαπημένη μου από αυτές P100  που στην Αμερική θα κυκλοφορήσει με επίσημη τιμή μόλις 400$ και σας παραθέτω το επίσημο δελτίο τύπου της εταιρείας.


With a 26x NIKKOR Zoom Lens, CMOS Image Sensor and Full HD Movie Recording, COOLPIX P100 Brings Compact Digital Camera Photography to a Whole New Level

MELVILLE, NY (Feb. 2, 2010) – Nikon Inc. today unveiled the new COOLPIX P100 digital camera, marking a series of firsts for Nikon with the debut of a CMOS image sensor and full High Definition (HD) movie (1080p) capabilities in the COOLPIX line. Additionally, with an expansive 26x Optical Wide Angle Zoom-NIKKOR ED glass lens and a 3.0-inch 460,000-dot vari-angle Clear Color Display LCD screen, the COOLPIX P100 delivers a compact camera fully equipped and readily able to expand a user’s photographic potential.

The COOLPIX P100 is Nikon’s first compact camera to offer full HD movie (1080p), allowing consumers to entertain audiences with movies that capture the entire impact of a scene at the touch of a dedicated movie-record button. A stereo microphone optimally mounted on top of the camera accurately captures audio to further enhance the video capture experience. Contributing to compositional freedom, both the optical zoom and autofocus functions are available while recording video. Additionally, the high-speed movie function provides the added benefit of recording movies that can be played back in slow motion or fast motion to create artistic effects. To further ease integration into an existing home theater system, an HDMI connector allows for easy playback on a compatible HDTV.

“Our portfolio of cameras is designed to ensure that any photographer, at any level, can find the camera that feels right for them,” said Bo Kajiwara, director of marketing, Nikon Inc. “The P100 blends a stellar lens with creative automatic and manual features to allow the more advanced consumer to explore the boundaries of their photographic capabilities.”

The Nikon COOLPIX P100 digital camera features a 10.3-megapixel backside illumination CMOS sensor, which enables high-speed shooting at 10 frames per second (fps) at full resolution and exceptional image quality even when shooting in low light settings.  Other functions benefitting from the lower noise and exceptional image quality of the new CMOS image sensor include an in-camera high dynamic range (HDR) function, which merges images of the same scene to achieve a single image with a broad range of tonal detail. Additionally, the Night Landscape mode combines a series of consecutive shots taken at a fast shutter speed into a single image with reduced noise when taking handheld shots in night scenes.

The versatility of the COOLPIX P100 digital camera is also attributed to its new 26x Optical Wide Angle Zoom-NIKKOR ED glass lens. This lens offers unparalleled compositional freedom, with its wide angle (26mm) to super telephoto coverage (678mm). The broad focal range lets consumers capture a variety of shots and scenes, ranging from sweeping landscapes to action shots taking place far away on a sports field. For further versatility, this extraordinary lens allows the user to take images or video as close as 0.4 inches while in macro mode. As part of the flagship Performance Series of COOLPIX compact digital cameras, the COOLPIX P100 is the ideal photographic tool for photo enthusiasts, sports and travel photographers and consumers with more advanced photography skills who crave a high performance camera.

Additional features of the Nikon COOLPIX P100 digital camera include:

  • 10.3-megapixels and Backside Illumination CMOS Sensor for stunning prints as large as 16x 20 inches, while retaining fine detail
  • In-Camera High Dynamic Range (HDR) merges multiple images of the same scene to create an image with a range of tonal detail that could not be captured in a single photo
  • Night Landscape Mode combines a series of images into a reduced noise composite for low light shooting
  • 3.0-inch Vari-Angle 460,000-dot Clear Color Display LCD and Electronic Viewfinder make it easy to compose and share pictures with friends and family.  The new LCD, with anti-reflection coating, can tilt as much as 90 degrees up or 82 degrees down. This enables photographers to shoot from higher angles or from the hip. The incorporation of the an electronic viewfinder enables consumers to see through the lens in most any lighting condition
  • 5-Way Vibration Reduction (VR) Image Stabilization System
    • Optical VR Image Stabilization by image sensor shift compensates for the effects of camera shake, producing clearer, sharper results in lower lighting or unsteady conditions
    • Hybrid VR Image Stabilization combines both sensor shift VR and Electronic VR
    • Motion Detection automatically detects moving subjects and adjusts shutter speed and the ISO setting to compensate for camera shake and subject movement
    • High ISO 3200 capability creates new opportunities to take sharper, more natural-looking photos in lower light conditions (up to 10 megapixels)
    • Best Shot Selector (BSS) automatically takes up to 10 shots while the user presses the shutter, and saves the sharpest image
  • Program, Shutter Priority, Aperture Priority and Manual Exposure modes give ultimate creative control over images
  • New Sport Continuous Scene Modefor shooting at up to 10 fps at full resolution and 120 fps for 1.1-megapixel images
  • Subject Tracking automatically activates autofocus while tracking moving subjects such as children and animals.  Even when the subject momentarily moves out of the LCD frame, the camera will restart tracking if the subject returns in the frame within 3 seconds
  • Pre-shooting Cachelets users capture up to 40 shots before shutter is released. This setting helps photographers stay ahead of the action
  • Active D-Lighting minimizes loss of details in highlights and shadows resulting in beautiful, more natural-looking images
  • Smart Portrait System integrates the following features to make it a snap to capture stunning portrait photos of friends and family:
    • In-Camera Red-Eye FixTM automatically fixes most instances of red-eye
    • Enhanced Face-Priority AF can detect up to 12 faces from a variety of angles
    • Skin Softening ensures smooth skin tone on the face of subjects by leveraging built-in face-detection technology
    • Smile Mode automatically detects when a subject smiles and releases the shutter
    • Blink Warning notifies the user when a subject has blinked in a photo
    • Blink Proof detects the subject’s face and automatically takes a series of sequential shots, then saves the image in which the subject’s eyes are open

The Nikon COOLPIX P100 digital camera will be available nationwide in March 2010 and will retail for $399.95* MSRP. For more information on the P100 and all COOLPIX cameras, please visit

HTML επιτέλους 5.0

Φεβρουαρίου 4, 2010

Όσοι γνωρίζετε ότι η HTML, η γλώσσα στην οποία ουσιαστικά χτίζεται το WWW, ολοκληρώνει την τυποποίησή της έκδοση 5.0 ίσως αναρωτιέστε αν οι φήμες για τις μαγικές της ιδιότητες που θα αλλάξουν την εμπειρία του ιντερνετ είναι βάσιμες, προτείνω να διαβάσετε το εξαιρετικό ποστ του John Herrman στο Gizmodo.

Δεν θα μοιραστώ μαζί σας τα συμπεράσματά του αλλά μόνο την  κατάληξη του άρθρου του που ουσιαστικά δίνει και την ουσία της δυναμικής της HTML 5.0

HTML5 is infiltrating the web, not tearing it down and building it back up. Like the standard itself, the HTML5 web will evolve slowly, with web technologies gradually supplanting tools you use now. You’ll notice it, but you’ll have to watch closely
