John McCain’s pick for VP, Sarah Palin, knows a thing or two about retrieving evidence from a computer. The mainstream reporting calls her a “hacker” because she is able to retrieve files from the Windows recycle bin.
The Anchorage Daily News reports back in September 2004:
Sarah Palin never thought of herself as an investigator. Yet there she was, hacking uncomfortably into Randy Ruedrich’s computer, looking for evidence that the state Republican Party boss had broken the state ethics law while a member of the Alaska Oil & Gas Conservation Commission.
The next week, when Palin went back …

One of my old L0pht collegues, Peiter “Mudge” Zatko, is featured in Mass High Tech today in an article titled Bay State hackers find security holes in defibrillators, RFID.
Hackers getting a free T pass may be the least of our worries — local hackers-turned-security experts suggest RFID keycards, wireless networks and medical devices implanted in the body are also vulnerable to hacks.
At last week’s Defcon hacker convention in Las Vegas, a team of researchers showed it was possible to get information such as Social Security numbers and medical diagnoses, and change the settings on an implantable defibrillator by impersonating …

Earlier today, the US District Court dealt a victory to the MBTA hackers and the EFF, lifting the injunction issued on August 9th to prevent the three MIT students from presenting their findings at DEFCON 16. In summary:
The lawsuit claimed that the students’ planned presentation would violate the Computer Fraud and Abuse Act (CFAA) by enabling others to defraud the MBTA of transit fares. A different federal judge, meeting in a special Saturday session, ordered the trio not to disclose for ten days any information that could be used by others to get free subway rides.
“The judge …

A lot of the focus of the MBTA vs MIT case has been discussion of the CharlieCards. These are MiFare classic cards which have been known to be broken earlier this year. There is also a paper disposable card called the CharlieTicket that uses a magnetic stripe. The MIT students presentation states that these are cloneable and forgeable using a $150 magnetic stripe reader/writer.
From the Confidential Memo Prepared for the MBTA which was publicly disclosed by the MBTA is court filing:

This seems …

A hearing will be held in Boston tomorrow to decide whether or not the restraining order gagging the MIT students from talking about the vulnerabilities they have found should be lifted. Even though the Defcon presentation is widely available and the MBTA disclosed the “Confidential” memo from the MIT students in their court filings, they are seeking a permanent speech injunction. An august group of computer scientists has signed a letter which will be entered into the record for the case. This list includes: Dave Farber of Carnegie Mellon University, Steve Bellovin from Columbia University, David Wagner …

Another BlackHat has come and gone. As usual, it was a very busy week juggling customer meetings, recruiting, conference planning, vendor parties, and, oh yes, the actual BlackHat presentations. I had a fantastic time catching up with old friends and finally getting the opportunity to meet more of the Security Twits and others in the security community. I didn’t submit a talk this year, but nevertheless, fake Dan Kaminsky was still excited to see me.

My favorite talk, as expected, was the Sotirov/Dowd talk on …

It sure seems like the CharlieCard, which is used by the Boston subway system, has a serious security weakness. The MBTA has sued 3 MIT students to stop them from giving a planned talk at DEFCON.
Doesn’t this seem backwards to you? Shouldn’t the MBTA be suing the vendor who sold them the flawed system? Security problems go away by mandating independant security testing before a product is accepted, not by trying to get security researchers to be quiet. This is a good example of how the reactive approach doesn’t work. The flaws …

Three French journalists have been booted for life from Black Hat and Defcon for compromising the Black Hat press room wired network and grabbing the credentials for at least one reporter. Their goal was to publicize the risks to reporters especially current given the massive reporter presence in Bejing for the Olympics. This risk is certainly real and it is a shame that these journalists had to compromise and embarass one of their own and potentially run afoul of US Federal wiretap laws.

Sniffing, or monitoring all …

I’m not talking shipping as in boats, but shipping as in packages. David Maynor is giving a talk at Black Hat on his newest experiment: using a small and cheap WiFi platform that is remotely accessible over a WAN perform WiFi surveillance inside of a package delivered right to your victim. Guess what the cheap platform is? An iPhone of course. George Ou has some pictures and more details in his blog posting, The iPhone wireless LAN Ownage in a Box.
This new remote WiFi attack is particularly timely as a new indictment of 11 …
