Russian Elcomsoft Finds Backdoor in Quicken Passwords

Use Netsparker

Elcomsoft is quite a well known firm when it comes to password ‘recovery’, I have used their products in the past when I was in a fix and I needed a password that had been, you know…lost.

They rose to fame in 2001 after cracking Adobe’s eBook format.

Recently they announced a fairly serious backdoor in Quicken product for accounting.

A Russian firm that provides password-recovery services says it has found a backdoor in the encryption mechanism that Quicken uses to secure password-protected files, a feature that makes millions of users of the personal finance program more vulnerable to government spooks or other highly determined snoops.

Elcomsoft, which made waves in 2001 after it circulated software that circumvented digital rights management protections in Adobe’s eBooks, said the latest version of its Advanced Intuit Password Recovery product allows users to remove password protection from Quicken files.

It’s a pretty serious case seen as though a lot of small and medium enterprises hold all of their accounting and payroll data in Quicken databases. It could lead to some serious theft, if Elcomsoft can work out the backdoor I’m sure the bad guys can too.

According to a statement issued by Elcomsoft, Intuit since 2003 has secured password-protected Quicken files using “strong encryption” that for practical purposes makes brute-force attacks impossible. But Elcomsoft said the strong encryption is accompanied by a backdoor that lets Intuit unlock encrypted files using a 512-bit RSA key that until recently was known only to Intuit. The key enabled Intuit to deliver retrieval service for customers who could no longer remember their password.

“It is very unlikely that a casual hacker could have broken into Quicken’s password protection regimen,” Vladimir Katalov, Elcomsoft’s CEO, said in a statement. “Elcomsoft, a respected leader in the crypto community, needed to use its advanced decryption technology to uncover Intuit’s undocumented and well-hidden back door, and to successfully perform a factorization of their 512-bit RSA key.”

The skeptics would indeed say the escrow or backdoor is there to allow Quicken to make more money from password recovery, the conspiracy theorists would say it’s there for FBI/CIA/Homeland access to people’s account.

I’m undecided personally.

    I agree, they probably count on the fact that a certain percentage of their customers will loose their passwords at some point.

    Its a good thing I don’t have any money to keep track of!! ;)

    Coding in a “backdoor” as a precaution for retard customers is always a bad idea. The whole notion of it is passe, you might as well be watching the movie “Hackers”. Anyway, I prefer to use OpenOffice Spreadsheet and my brain to manage what little cash I got. If I ever really need a program specifically to keep track of my funds then I’ll hire an accountant or an accounting firm.

    Remember kids, trusting other people’s code with your money/accounts/investments is like trusting a politician to tell the truth.

    Well based on the fact that ppl will legitamately loose their passwords, this is helpful. But what about those that will loose this maliciously.

    I guess it maybe too much work to put some type of 2 factor authentication into some applications, in the event that your password is cracked, you make need a file that’s physically on the machine to open the file, and it should be a file that you chose as “key file”.

    Yeah, this sucks. While it may not matter to people in lower tax brackets (me), it sucks for all those small and medium sized businesses whose accounting departments rely on this software to manage payroll, accounts receivable, etc.

    Hmmm, I would like to think that accountants and people running payroll could actually think instead of letting a program think for them. This is what happens when you let a company decide how to “think” for you. You are at their mercy. I am waiting to hear government hacks company to find out true earnings for the company. Put I’m just paranoid :P

    I agree with the other people in the commentary this is a way to make money. You forget your password you have to call support. Guess what? Support = Dollars. To Quicken dollars makes sense. :)

    Thanks Alfred

    I’ll take that as compliment… I can probably help out government in implementing new technologies in a better way…
