    ‘Redirect to SMB vulnerability’: Return of the credential stealer

    May 12, 2015

    Hackers always have a targeted interest in credentials. Just like a burglar would prefer to have a key to a house, credentials provide them easy access to systems. Quite often, a seemingly innocent way of working can be tweaked slightly to be used in a nefarious way. This also applies to a vulnerability called “Redirect to SMB”, which is a variation on an old attack.

    Impact on SSL from the revised PCI DSS v3.1 Standard on organisations handling cardholder data

    Apr 27, 2015

    The recently announced updates to the PCI DSS standard result in all versions of the SSL protocol and early versions of the TLS protocol (TLS v1.0) no longer meeting the PCI SSC’s definition of “strong cryptography”. Organisations handling cardholder data must seek to be compliant with these revised standards and will be required to make changes to their IT infrastructures by discontinuing the use of SSL and TLS v1.0 and moving to more suitable options by 30 June 2016. The suitable options at present are the recent versions of TLS giving preference to the latest version of TLS, v1.2 as a long term solution.

    How the ‘FREAK’ attack is affecting our devices

    Apr 08, 2015

    It looks like the security mechanisms commonly used by our web browsers are not done with getting bad press. The “Transport Layer Security (TLS)” technology and its predecessor, “Secure Sockets Layer (SSL)”, are cryptographic mechanisms designed to provide communications security over a computer network and are used literally everywhere. Recently, a group of cryptographers at INRIA, Microsoft Research and IMDEA discovered a new bug affecting this technology which is now known as the “FREAK” attack (Factoring RSA Export Keys). Devices shown to be affected by FREAK include iPhones, Android devices and Macs running OS X.
