Missing in Action At BlackHat: The PC

June 3, 2013 Paul Roberts

Once the target of choice for hackers of all stripes, personal computers (PC) will be -at most- a side attraction at this year’s annual Black Hat Briefings show in Las Vegas, where presentations on ways to attack mobile devices and other networked “stuff” will take center stage. Just over ten percent of the scheduled talks and turbo talks at The Black Hat Briefings in early August (5 of 47) will be devoted to attacks against what might be considered “traditional” endpoints, like end user systems and servers running Microsoft’s Windows, Apple’s Mac OSX and Linux. By contrast, more than 30% will discuss security flaws and attacks against mobile phones or other “smart” devices including wireless surveillance cameras, home automation systems and smart meters. The dearth of PC-focused talks isn’t a new trend in and of itself. As far back as 2006, talks that explicitly discussed security issues with components of Microsoft’s […]

Update: Researchers Use Weezer Tune To Knock Defibrillators Offline

May 21, 2013 Paul Roberts

Editor’s Note: This article has been updated to include comment from Medtronic and from the researchers. A bit more on that: I spoke to the fine researchers who conducted this study. They are concerned that people might casually read the headline or first couple paragraphs and conclude that listening to Weezer will kill them. Listening to Weezer will not kill you. Listening to Weezer will not interfere with your implanted defibrillator if used under normal conditions. Their experiment (and my article) make this clear, but you do have to read down a bit in the article to get that, and I know not everyone does that. In any case, the health benefits of using an implanted defibrillator in accordance with your doctor’s instructions, far outweigh any risk from EMI or other electronic tampering. – PFR 5/22/2013. Listening to Weezer could kill you. Literally. That’s the conclusion of an unusual experiment […]

Fitbitten: Researchers Exploit Health Monitor To Earn Workout Rewards

May 2, 2013 Paul Roberts

Call it “the quantified self” – that intersection of powerful, IP-enabled personal health monitoring tools and (usually) Web based tools for aggregating, analyzing and reporting. The last five years has brought an explosion in these products. In addition to the long-popular gear like Garmin GPS watches – must have items for the exercise addicted – there’s a whole range of new tools for the merely “exercise curious” or folks interested in losing weight or just figure out what, exactly, they do all day. Count Nike’s FuelBand, Jawbone’s UP, and Fitbit in that category. Alas, a growing number of reports suggest that, when it comes to medical devices and health monitoring tools, the security of sensitive personal data isn’t a top priority. The latest news comes by way of researchers at Florida International University in Miami, Florida. A team of three researchers, composed of students and faculty, analyzed the Fitbit health monitoring device […]

Botnet Of Embedded Devices Used To Map Internet

March 19, 2013 Paul Roberts

Botnets are mostly linked with spam e-mail campaigns, denial of service attacks and data theft. But global networks of compromised hosts can be used for a variety of ends – not all of them malicious. That was the idea behind “Internet Census 2012,” a stealth project by an unnamed and unknown researcher/hacker to map the entire IPV4 Internet address space using a massive network of compromised devices. The results, published in the form of a research paper, underscore the problem of unsecured embedded devices, including set top boxes, home routers and critical infrastructure, with the hacker able to locate and compromise these systems, creating a botnet of more than 420,000 nodes. According to a copy of the report, the project grew out of an experiment to locate unprotected devices online using nmap, the open source scanning tool. By compromising each vulnerable host and then enlisting it to scan for other […]

Malware’s Future Looks A Lot Like Its Present

February 28, 2013 Paul Roberts

SAN FRANCISCO – What does the future of malicious software look like? Depressingly like the present, according to a panel of leading experts. Phishing attacks, spam and even self-propagating worms will continue to plague technology users in the years ahead, just as they have for much of the last two decades, according to experts at the RSA Security Conference in San Francisco on Wednesday. However, the malware will operate across a far more crowded landscape of mobile devices, virtual machines, cloud-based computing resources and Internet connected “stuff” – complicating the job of securing sensitive information. The panel, “50 Minutes into the Future: Tomorrow’s Malware Threats” asked the experts to look into the crystal ball and predict what malicious software would look like in the near- and distant future. The answer was: much like it looks today. Dave Marcus, the director of security research and communications at McAfee Labs, said that the […]
