●● Why Crackers Prefer Windows on Cash Machines

Summary: Windows makes a lot of money for the bad guys, who are exploiting Windows-based ATMs

ATMs that run Windows are running for criminals to take advantage of them. This is a subject that we covered many times before along with examples. See the following older posts for background:

Here is Slashdot’s summary about the latest example:

“Windows CE-based ATMs can easily be made to dole out cash, according to security researcher Barnaby Jack. Exploiting bugs in two different ATM machines at Black Hat, the researcher from IOActive was able to get them to spit out money on demand and record sensitive data from the cards of people who used them. Jack believes a large number of ATMs have remote management tools that can be accessed over a telephone. After experimenting with two machines he purchased, Jack developed a way of bypassing the remote authentication system and installing a homemade rootkit, named Scrooge,”

The machines Jack hacked were, however, based on Microsoft’s Windows CE operating system.

At the Black Hat security conference here, Jack demonstrated two different attacks against Windows CE-based ATMs — a physical attack using a master key purchased on the Web and a USB stick to overwrite the machine’s firmware; and a remote attack that exploited a flaw in the way ATMs authenticate firmware upgrades.

Glyn Moody cannot comprehend such a tactless choice of Windows CE for ATMs. He asks, “why not just leave the notes out in the open?”

It should be no surprise that Google’s vulnerabilities in Chrome are sometimes caused by Windows’ inherent insecurity and this time for a change, “Google patches Chrome, sidesteps Windows kernel bug,” reports IDG. “Microsoft was not available for comment late Tuesday.”

It it worth adding that many Firefox flaws are Windows-only as well. Sometimes GNU/Linux is also affected and this new article says that “Google also released workarounds for two vulnerabilities in external components, helping to protect from flaws in the Windows kernel and GNU glibc components.” Nothing is infallible, but Microsoft tends to fail more often than the rest and it hides this. █
