Warning from security researchers at Malwarebytes, there is a new malware threat recently, which Bitcoin miners are bundled with third party potentially unwanted programs (PUPs) that come bundled with legitimate applications.

The malware is using ‘jhProtominer’, a popular mining software that runs via the command line. It abuse the CPUs and GPUs of infected computers to generate Bitcoins. ‘jhProtominer’ bundled with ‘monitor.exe’, which is a part of “YourFreeProxy” application. The ‘monitor.exe’ is waiting for commands from a remote server, eventually downloading the miner and installing it on the system.

“YourFreePorxy” is owned by Mutual Public AKA We Build Toolbars, it is proxy server. However, this application bundle a malware which will use users’ computer to mine Bitcoins. Actually, this feature appears in their terms of service.

COMPUTER CALCULATIONS, SECURITY: as part of downloading a Mutual Public, your computer may do mathematical calculations for our affiliated networks to confirm transactions and increase security. Any rewards or fees collected by WBT or our affiliates are the sole property of WBT and our affiliates.

One of the user reported to Malwarebytes that saw a 50% increase in processor usage when installed the toolbar. Maybe that mining software could be flagged as malware.

Showing Blank White Screen

This is one the problem I faced when using iTunes Store on Mac OS 10.6.8 Snow Leopard, My Mac iTunes Store is showing blank white screen. When I open iTunes and choose the iTunes Store. It’s showing blank white screen but it’s fine when I choose the Library. At first, I thought it’s internet problem. I decided try to access after few days. The problem is still there. I wonder that why this happen and I confirm that my internet connection is fine. I check the latest update, my iTunes version is the current version. I also tried download iTunes from Apple website and installed it. I still faced the same problem.

Safari Update

After some research, I found out what is the reason cause this. Although I had update the latest version of iTunes, but I didn’t complete all the Software Update. I need to do the Safari Update to solve this problem.

By the way, I think that this problem only happen on Mac OS 10.6.8 Snow Leopard. Do the Safari Update, and it’s worked for me.

Now, I able to access to iTunes Store without show any blank white screen.

Safari 5.1.10 for Snow Leopard

I like to share what I know and I learn. Please do hesitate to contact me if you found out any mistake.
