A hacking tool gets updated for the Mac

Hackers are making the Mac a 'first-class target' for the popular Metasploit toolkit.

Two well-known Mac hackers are updating a widely used hacking toolkit, making it easier to take control of a Macintosh computer.

Over the past few days, the researchers have been quietly adding new software to the Metasploit toolkit, used by security researchers and criminals alike. Metasploit already supported Mac attacks, but until recently the Mac code hadn't been as good as Metasploit's Windows and Linux tools, said Dino Dai Zovi, an independent security researcher who talked about the new tools with his collaborator Charlie Miller at the CanSecWest conference Friday. "Our goal was to make Mac OS X a first-class target for Metasploit."

Metasploit is an open-source toolkit that makes it easy for hackers to launch a barrage of attacks against a computer system.

Miller and Dai Zovi earned fame in previous years for hacking Macintosh computers at CanSecWest's annual Pwn2Own hacking contest. On Wednesday, Miller, a researcher with Independent Security Evaluators, won US$5,000 and a Mac laptop by using a previously unknown Safari vulnerability to hack into a Mac system.

The hack was done before contest organizers. In an interview, Miller said he had hoped to demonstrate it before an audience at CanSecWest, but was prevented from doing so because of Pwn2Own contest rules, which prohibit public discussion of bugs exploited in the contest.

Miller and Dai Zovi say their work is designed to bring attention to serious security problems in the Mac platform, which has largely avoided the wide-scale attacks that have plagued Windows for years. Dai Zovi said he considers the Mac safe, but not secure. "There's a difference between safety and security," he said. "It's like leaving your door unlocked. ... Leaving your door unlocked is always insecure, but it may or may not be safe."

At the show, the researchers demonstrated several payload programs they have developed for Metasploit, including one called "Pic the Vic," which can be used to snap a photograph of a Mac user who has been hacked, using the computer's camera.

They have also ported a Windows tool, called Meterpreter, to the Mac. Meterpreter is a stealth tool that can be used to gain information from and import more software onto a hacked computer.

In the next few days they plan to add exploit code to Metasploit for a handful of previously patched Mac software bugs. Exploit code must be used to first hack into the computer before any payload software can be installed.

Although there are still many more exploits available for Windows software than for Macs, the new payload code means there is now "more or less the same functionality if you want to target a Mac box or a Windows box," Miller said.

I've had a multifunction printer in the office going on 10 years now. It was a neat bit of kit back in the day -- print, copy, scan, fax -- when printing over WiFi felt a bit like magic. It’s seen better days though and an upgrade’s well overdue. This HP OfficeJet Pro 8730 looks like it ticks all the same boxes: print, copy, scan, and fax. (Really? Does anyone fax anything any more? I guess it's good to know the facility’s there, just in case.) Printing over WiFi is more-or- less standard these days.

I’d happily recommend this touchscreen laptop and Windows 10 as a great way to get serious work done at a desk or on the road.

Ultimately, I think the Windows 10 environment is excellent for me as it caters for so many different uses. The inclusion of the Xbox app is also great for when you need some downtime too!

For me, the Xbox Play Anywhere is a great new feature as it allows you to play your current Xbox games with higher resolutions and better graphics without forking out extra cash for another copy. Although available titles are still scarce, but I’m sure it will grow in time.
