bitcoinA new Mac OS X trojan horse that monitors web browsing traffic in order to steal Bitcoins has been discovered by SecureMac. The trojan, called OSX/CoinThief.A, is disguised as an innocuous Bitcoin app called StealthBit that purports to send and receive anonymous payments.

The app was posted on open-source website GitHub, but the precompiled version of the app had the malicious payload installed. The malware installs browser extensions in Safari and Google Chrome looking for login credentials for a number of Bitcoin related websites including MtGox, BTC-e, and blockchain.info. When the app finds login credentials, it sends those back to the malware's developer.

Initial infection occurs when a user installs and runs an app called "StealthBit," which was recently available for download on GitHub, a website that acts as a repository for open source code. The source code to StealthBit was originally posted on GitHub, along with a precompiled copy of the app for download. The precompiled version of StealthBit did not match a copy generated from the source code, as it contained a malicious payload. Users who downloaded and ran the precompiled version of StealthBit instead ended up with infected systems. A user posting over the weekend on Reddit, the popular discussion site, reported losing 20 Bitcoins (currently worth upwards of $12,000 USD) to the thieves.

Bitcoin users who may have downloaded the app should check their browser extensions in Safari and Google Chrome for generic "Pop-Up Blocker" extensions.

GitHub blew it. They should check all packages before hosting them.
Yes, GitHub should check the million lines of code and the hunderds of packages uploaded every second to make sure there isn't any malicious code in there.

If you don't know what you're talking about, just don't say anything.

You're willingly turning over your login and pass and admin access to your computer. No operating system in the world will stop this type of thing from gain access when you hand it the keys. It's not your security systems fault if you give the burglar your alarm code.

That's about as good as NBC's "All visitors to Sochi Immediately Hacked" claim:



Their claims were thoroughly debunked in the article That NBC story 100% fraudulent (http://blog.erratasec.com/2014/02/that-nbc-story-100-fraudulent.html). If I were Putin, I would have ejected the "journalist" who filed that story. :rolleyes:
