Phoney and the forensics value of Iphone chat

Phoneys is a software that allows a user to change the content of an Iphone chat thus altering the meaning of the conversation.While this is just an entertainment software, it might have some disturbing impacts on a possible criminal investigation.

Indeed, SMS, chat transcripts and messages are routinely used as a source of evidence by lawyers and prosecutors on the basis that if something is on a phone it can be hardly be faked. Of course, this is not always true, of course evidences must be corroborated by independent checks, of course the legal community is not that dumb to give face value to a text on a phone screen. But…

Phoneys allows a malicious person to create a prima facie deceiving fact, by exploiting the fact that a message has actually been sent, thus leading the investigator into thinking that a conversation took place with the intended correspondent. In an emergency context, the necessity of taking immediate action might push him to under evaluate what has been shown as “evidence”, thus jeopardizing the final result.

Maybe this is a either a minor or non-existent issue. But judicial reality has proven to be more surprising then legal-thriller. So, next time you’re confronted with a message as an evidence, why not double check?

Just in case…

Italian Digital Signature Software Exposed to Man-in-the-middle Attack?

An independent researcher compiled a list of known Apple OSX-related vulnerabilities, including one that affects the Sparkle Updater Framework.

I’ve just checked my Mac with this command

find /Applications -name Sparkle.framework

and found that DikeX, the old version of the digital-signature tool released by Infocert S.p.a., uses Sparkle. I don’t know if the software is plagued by the bug, but this is exactly the point: nobody from Infocert just warned users with a single word about.

Does SHA-7 belong to the US NSA?

As everybody knows, the SHA-n is a series of cryptographic algorithm developed by the NSA and published by the US NIST. The current SHA-n lineup includes SHA-1, SHA-224, SHA-256, SHA-384 and SHA-512.

On the contrary, SHA-7 (see this link – italian only, sorry), a “proprietary, patented encryption algorythm” developed by an Italian company doesn’t belong to the original “family”. And doesn’t have any endorsement by the scientific community.

I wonder why SHA-7 designers have choses this confusing name for their code.



Infocert, electronic signature and technology discrimination

Here we are again. Infocert – one of the biggest electronic signature provider in Italy – confirmed its technology lock-in attitude, by pushing users toward Microsoft Windows.

Infocert released  its USB based all-in-one solution named Businesskey and advertises its dongle as an “hassle-free” tool, with no installation required. This is not entirely true, because the system only works under Microsoft Windows: no Linux or Mac OSX support.  Admittedly, Infocert did release a Linux and MacOSX desktop-based version of Dike (the software client needed to handle the electronic signature), but didn’t do the same as “portable app”.

Consequences are clear and don’t need further explanation. What is astonishing is the silence of both Government and Authorities, that are allowing private entities to force citizens to pay non irrelevant monies to get public services.
