Human RFID Data Mining

Every other year, 2600: The Hacker Quarterly throws its Hackers on Planet Earth bash in NYC, and every year, they have elaborate, hackable badges. Lately, these have been OpenAMD RFID badges, whose in-built RFID tags can be hacked, tracked, monitored, spindled, folded and mutilated.

This year’s badge sports its own API, for your hacking pleasure:

PopoutConference attendees will see first hand where human tracking by commercial and government interests may be headed when they are offered an active RFID conference badge.

Participation in RFID tracking is completely voluntary. If you wish, you can request an electronics-free “unpopulated” badge at registration, or simply remove the battery from your “populated” RFID badge at any time. There will be a limited number of the full-featured badges, so register early to be guaranteed to receive one.

Human Computer Virus!

The machines are going to take over.

And so a British scientist says he is the first man in the world to become infected with a computer virus. Dr. Mark Gasson from the University of Reading, who sadly does not have wild white hair, contaminated a computer chip which was then inserted under the skin in his hand.

The gizmo, which enables him to pass through security doors and activate his mobile phone, is a version of the ID chips used to tag your pet dog.

In trials, Dr. Gasson showed that the chip was able to pass on the computer virus to other control systems, though, hopefully, not including his nervous system. The doc thinks this has important implications for a future where medical devices such as pacemakers become more sophisticated and risk being contaminated by other human implants.

Gasson also predicts that implanted technology will spread: “This type of technology has been commercialized in the United States as a type of medical alert bracelet, so that if you’re found unconscious you can be scanned and your medical history brought up.”

We give it three weeks before Gasson begins to morph into a cyborg. Watch the video of the man looking human while you still can.

Internet Takeover by FCC

House Republican Leader John Boehner (Ohio) is using language from the just-completed healthcare debate to blast the FCC’s attempt to rein in broadband providers.

Boehner accused the agency Thursday of pursuing a “government takeover of the Internet,” just hours after FCC Chairman Julius Genachowski unveiled the plan, which would place broadband providers under some of the same rules that have long governed phone companies.

“Under this job-killing big government scheme, the Obama administration is seeking to expand the power of the federal government,” Boehner said in a statement.

“The success of the Internet is a perfect example of what happens when entrepreneurship and innovation are allowed to flourish, but today’s decision will undermine its success and hurt our economy,” the GOP leader continued. “The American people are asking ‘Where are the jobs?’  They aren’t asking for yet another government takeover that imposes new job-killing federal regulations and puts bureaucrats in charge of the Internet.

Republicans attacked the healthcare bill for almost a year as a job-killer and a government takeover of private enterprise. They’ve made similar arguments about other efforts — some of which were backed by Republicans, including the Bush administration — to bailout banks and auto companies.

The FCC, however, has explicitly sought to shed any mention that hope to regulate or takeover the Internet. Rather, the commission has framed its efforts as an attempt to store the same rules and procedures that were in place before a federal court in April invalidated the FCC’s ability to regulate broadband providers.

Two FCC officials on a conference call with reporters on Thursday declined to address Boehner’s criticisms directly. They also noted that full implementation of Genachowski’s proposal — including rules that would safeguard open Internet — was still some time away.

But Boehner on Thursday implored lawmakers to act preemptively to stop the FCC from encroaching too much on private business.

“Congress should listen to the American people and act to reverse this unnecessary federal government power grab,” he said.

Internet Explorer Finally Fades Away!

Microsoft’s Internet Explorer browser market share has dipped to a historic all-time-low in April, at under 60 percent, according the latest NetApplications statistics. Internet Explorer’s losses are at the expense of Mozilla’s Firefox and Google’s Chrome browser which continue to grow more popular.

For the first time since Internet Explorer 4 won over Netscape over 10 years ago, Microsoft’s browser has dropped in usage to 59.95 per cent market share in April this year. Internet Explorer had an 80 percent market share less than two years ago.

NetApplications browser market share statistics for April 2010.NetApplications browser market share statistics for April 2010.

According to the NetApplications statistics, Mozilla’s Firefox browser now has nearly 25 percent market share, and has been stationery for the last two months at around a quarter of the market. Firefox is still the largest threat to Internet Explorer‘s dominance.

Lower down in the NetApplication rankings was Google’s Chrome (6.7 percent), leading the WebKit-powered browsers, ahead of Apple’s Safari (4.7 percent). Chrome’s surge in use is impressive, considering it had zero percent share prior to 2009.

Opera, which has been recently in the news with their new Opera Mini browser for iPhone, commands only 2.3 percent of the market in the NetApplications statistics.

NetApplciation’s numbers are not too far off from StatCounter data either, which says that Internet Explorer has 56.5 percent of the market share, followed by Firefox with 31.3 per cent, then by Chrome and Safari with 5.3 and 3.6 percent respectively. StatCounter measures Opera at 2.2 percent.

Nielsen data on the other hand, via a BBC report, suggest that Internet Explorer has not lost much ground against its fellow rival browsers, and still commands 70 per cent of the market, while Mozilla has only 18 percent.

How to fix your McAfee-crippled computer

McAfee pushed out a malformed security patch early on Wednesday that wound up crippling computers running Windows XP, but there is a fix available. Users should note that it’s labor-intensive and must be applied manually to each computer. If you’re running Windows Vista or Windows 7, your computer shouldn’t be affected by the bad update.

As of 3 p.m. PDT, McAfee had yet to link on its front door to a fix for a false positive update with disastrous consequences that went out Wednesday morning.

If your computer is shutting down automatically, you must address that before you can fix anything else.

  • Step 1: Open a command prompt: Start menu, Run, then type cmd and hit Enter
  • Step 2: Type shutdown -a, which will prevent the shutdown from occurringMcAfee has revealed two fixes for the problem. Each one requires multiple steps, and can be confusing. If you’re not comfortable with advanced computer fixes, you should get help with this.For the first fix, go to the McAfee interface through the Start menu, and disable Access Protection and On-Access Scanner.
  • Step 1: Click Start, Programs, McAfee, and then VirusScan Console
  • Step 2: Right-click “Access Protection”
  • Step 3: Select “Disable”If you have Internet access, download the EXTRA.ZIP file provided by McAfee and unzip the EXTRA.DAT within. (Note that Nai.com is a safe site maintained by McAfee, for those who were wondering.) Once EXTRA.DAT has been extracted:
  • Step 1: Click Start, Run, then type services.msc and click “OK”
  • Step 2: Right-click the McAfee McShield service and select “Stop”
  • Step 3: Copy EXTRA.DAT to “Program FilesCommon FilesMcAfeeEngine”
  • Step 4: Then restart the McAfee McShield service by right-clicking on it and choosing “Start” from the context menu
  • Step 5: Re-enable access protection by going back to the VirusScan Console
  • Step 6: Right-click “Access Protection”
  • Step 7: Select “Enable”
  • Step 8: In the VirusScan Console, go to the Quarantine Manager Policy
  • Step 9: Click the Manager tab
  • Step 10: Right-click on each file in the Quarantine and choose “Restore”There is, of course, one massive hang-up with this McAfee-recommended solution: More likely than not, you don’t have Internet access on your McAfee-borked computer. In fact, it’s highly unlikely that you have access to much of anything, since deleting SVCHOST.EXE prevents key Windows 32-bit sub-system processes from functioning at all. To get the EXTRA.DAT on your computer, you’ll probably have to download it on an unaffected computer, then copy it to either a USB drive or a CD-ROM and use the command prompt to copy it over to your C: drive.The second workaround requires that you apply the EXTRA.DAT fix as detailed above before beginning and that you have access to a second, unaffected Windows XP computer. On that computer, go to C:WINDOWSsystem32 and copy SVCHOST.EXE to a network location or a removable media device such as a USB stick. Then copy the SVCHOST.EXE from the unaffected computer to the affected computer, and restart the McAfee-afflicted computer. There are details on applying the EXTRA.DAT via ePolicy Orchestrator at McAfee’s fix on Nai.com.Severe problems caused by buggy or false positive security updates are rare, but not unheard of. Recent instances include an update from Avast that marked hundreds of legitimate files as threats in December 2009, Computer Associates flagging a Windows system file as a virus in July 2009, and AVG marking ZoneAlarm as malware in October 2008.

    McAfee did not immediately responded to a request for comment.

    Updated at 5 p.m. PDT with additional information.

    McAfee Executive Vice President of Technical Support and Customer Service Brian MacPherson has written a blog post and a follow-up commenting on the situation, although neither addresses how the bad update made it past quality-control testing in the first place.

    Infected PC? AVG Rescue CD to the Rescue! | Business Hacks | BNET

    Infected PC? AVG Rescue CD to the Rescue! | Business Hacks | BNET.

    If a virus or spyware infection strikes your PC, you’ll know it right away. The telltale signs include suddenly sluggish performance, a hijacked Web browser, and/or pop-up warnings from sources you don’t recognize.

    What you may not know is what to do about it. Trying to cure an already infected PC is quite literally like trying to close the barn door after the horses have run out.

    Fortunately, there’s a new weapon at your disposal: AVG Rescue CD can remove viruses, spyware, and other malware from infected PCs. It’s a free, effective, and potentially life-saving tool — but there’s one catch.

    The catch: You need to create your rescue CD before your system gets infected. If you wait until after the fact, your system will probably be too choked with malware to perform the setup. So think of this as stockpiling a flu vaccine.

    As its name implies, AVG Rescue CD is a bootable CD that employs Linux for its operations, meaning it doesn’t boot into Windows (which is where the problems lie, natch). It’s also available for USB flash drives, which is my preferred method of deploying the tool — as long as the infected system supports booting from flash drives, which most modern PCs do. (The software itself requires only about 70MB of space, so even an old 128MB drive will suffice.)

    Don’t worry about out-of-date virus definitions: The software will leverage your PC’s Internet connection to retrieve the latest updates.

    I can’t say AVG Rescue CD is the most user-friendly tool I’ve used, so it behooves novice users to watch AVG’s two tutorial videos: One on creating a bootable CD or USB drive, the other on using Rescue CD to remove infections from a PC.

    I also can’t promise that the software will rescue every PC from every infection — but it’s something every user should keep in his or her toolkit. AVG Rescue CD is free; it works with most versions of Windows. [via AppScout]
