Hackers use open source tool

A new open source tool called Crapto1, which decrypts communication data between RFID chips and readers, could allow hackers free travel on the London Underground, reports PC Pro.

The software allows the access code of a Mifare chip to be decoded within two seconds on a standard PC, opening the door for manipulation of data stored on the card. This would allow hackers to gain free access to the system.

As well as powering the London Underground's ticket system, Mifare is also used in the Dutch public transport system and in numerous office secure-entry systems.

Yahoo's Zimbra messaging and collaboration software unit has released Zimbra Hosted, a software as a service version of its suite, says eWeek.

Zimbra Hosted is designed to remove the burden from colleges and universities of running software on their own hardware. It is also an open source alternative to competing cloud computing products from Google and Microsoft.

Zimbra Hosted keeps educational institutions from managing the software on their own servers, and customers will not need to implement software upgrades, pay for maintenance or add more hardware.

Aptana has released Version 1.0 of its Ajax server as well as open source Jaxer Pro, a commercially supported version of the Jaxer technology, states eWeek.

Aptana provides a Web development, deployment and management suite that includes Ajax, JavaScript, Ruby on Rails, PHP and Python support.

Kevin Hakman, director of evangelism for Aptana, says Jaxer embeds the open source Mozilla Firefox browser engine within a server so developers can have the same execution environment on the application server that they have in the Web browser.
