Facebook Introduces OTP (One-time Password) Functionality

Nice to see an innovation on the security front for once rather than endless ‘feature’ updates and announcements of ‘the next big thing’. Facebook has had its fair share of security woes so it’s nice to see they are doing something which I think may be genuinely useful for it’s burgeoning user base. A lot [...]

Website Auto-complete Leaks Data Even Over Encrypted Link

I’m always fascinated by side-channel attacks where the attack is focused on the underlying architecture of the cryptosystem and the data echos it creates rather than the algorithm or implementation itself. Similar somewhat to the recent breaking of OpenSSL using power fluctuations. This time some researcher type fellas focused on the digital noise autocomplete webforms [...]

Boffins Crack OpenSSL Library Using Power Fluctuations

Now this is a very interesting technique, as far as I know I’ve not seen anything similar to this before. It’s like a rather bizarre meld of hardware hacking and software exploitation using cryptographic algorithm cracking techniques. Some rather smart fellas have found a way to extract the private SSL key from a device by [...]

Ensuring Data Security During Hardware Disposal

After our recent story about the trading of BlackBerries for data theft the issue has emerged again this time more towards the secure disposal of data stored on PC hard disks. If a company or organisation has a decent data/information security policy in place (Like ISO27001 for example) they should have a secure destruction/disposal policy [...]

THC-ePassports – THC Clones Biometric ePassport – Elvis Presley Passport

I guess most people have been led to believe this new generation of ePassports or biometric passports are more secure, will help us keep our privacy intact and help us mitigate against identity theft. Well how wrong the propaganda is! THC (famous for their tools and research in security) has just released some technical information, [...]

Hackers Crack London Tube Oyster Card

It just goes to show, having an aluminium lined wallet could really be useful! Hackers in the Netherlands found they could clone an access card using the Mifare chip, after that they traveled to London to try their technique out on the Oyster card (used on the London Underground), which uses the same chip. It [...]
