New MacDefender Defeats Apple Security Update 427

XxtraLarGe writes "Apple released a security update yesterday designed to rid Macs of the menacing MacDefender malware that has plagued users for nearly a month. But mere hours after the update, cyber-criminals released a new variant of the malware that easily defeated Apple's belated security efforts. That didn't take long."

Apple Keyboard Firmware Hack Demonstrated 275

Anonymouse writes with this excerpt from SemiAccurate: "Apple keyboards are vulnerable to a hack that puts keyloggers and malware directly into the device's firmware. This could be a serious problem, and now that the presentation and code (PDF) is out there, the bad guys will surely be exploiting it. The vulnerability was discovered by K. Chen, and he gave a talk on it at Black Hat this year (PDF). The concept is simple: a modern Apple keyboard has about 8K of flash memory, and 256 bytes of working RAM. For the intelligent, this is more than enough space to have a field day. ... The new firmware can do anything you want it to. Chen demonstrated code which, when you put in a password and hit return, starts playing back the last five characters typed in, LIFO. It is a rudimentary keylogger; a proof of concept more than anything else. Since there is about 1K of flash free in the keyboard itself, you can log quite a few keystrokes totally transparently."
