Bitcoin ‘Sextortion’ Malware Is Even Worse Than Thought
Bitcoin - The Currency of the Internet
A community dedicated to Bitcoin, the currency of the Internet. Bitcoin is a distributed, worldwide, decentralized digital money. Bitcoins are issued and managed without any central authority whatsoever: there is no government, company, or bank in charge of Bitcoin. You might be interested in Bitcoin if you like cryptography, distributed peer-to-peer systems, or economics. A large percentage of Bitcoin enthusiasts are libertarians, though people of all political philosophies are welcome.
My story is weird and I don't know if I'm crazy or not. I use my computer mostly for university stuff and right now quite often due to the current situation. My most used programs are Google Chrome, Word, Spotify and Powerpoint which, in my opinion, aren't video editing/ AAA game tier programs. Now here comes the weird part - whenever I open my task manager, it ALWAYS drops down from 40-30% to 10-3% CPU usage. It happens all the time, without a fail. I'm confused about this. Also when I play low-performance games, CPU usage ups to full 100%, helicopter throttle and then drops down 70-60% when I check it out. I'm mentioning bitcoin malware because I have heard about that they can be smart about what they are doing. Am I possibly overreacting or is my issue real?
How to remove a bitcoin malware that infected my computer from a game?
So i downloaded a game , which doesn't use any internet what-so-ever but whenever i play it my cpu/gpu and internet spikes a lot so this leads me to think that there is a bitcoin miner malware of some sorts , but my antivirus doesn't detect anything. Is there a way to remove the malware by itself or do i have to delete the game for sure?
The rise of Bitcoin and digital currencies has also led to an increase in theft and security issues as 99% of Bitcoin malware is targeted at Windows users. Nearly 150 types of this malware are circulating as of Feb. 2014.

The following post by Amichateur is being replicated because some comments within the post(but not the post itself) have been silently removed. The original post can be found(in censored form) at this link: np.reddit.com/ Bitcoin/comments/7kas0k The original post's content was as follows:
I downloaded an audio driver from somewhere I shouldn't have and the next thing I know was that my cpu was running at 99%. If I had not caught it as soon as I did it could have caused some serious harm to my pc. So my question is am I still vulnerable and why didn't my antiviral catch this. (I used malwarebytes to remove it)
Proposal to address Bitcoin malware | Brian Erdelyi | Jan 31 2015
Brian Erdelyi on Jan 31 2015: Hello all, The number of incidents involving malware targeting bitcoin users continues to rise. One category of virus I find particularly nasty is when the bitcoin address you are trying to send money to is modified before the transaction is signed and recorded in the block chain. This behaviour allows the malware to evade two-factor authentication by becoming active only when the bitcoin address is entered. This is very similar to how man-in-the-browser malware attack online banking websites. Out of band transaction verification/signing is one method used with online banking to help protect against this. This can be done in a variety of ways with SMS, voice, mobile app or even security tokens. This video demonstrates how HSBC uses a security token to verify transactions online. https://www.youtube.com/watch?v=Sh2Iha88agE <https://www.youtube.com/watch?v=Sh2Iha88agE>. Many Bitcoin wallets and services already use Open Authentication (OATH) based one-time passwords (OTP). Is there any interest (or existing work) in in the Bitcoin community adopting the OATH Challenge-Response Algorithm (OCRA) for verifying transactions? I know there are other forms of malware, however, I want to get thoughts on this approach as it would involve the use of a decimal representation of the bitcoin address (depending on particular application). In the HSBC example (see YouTube video above), this was the last 8 digits of the recipient’s account number. Would it make sense to convert a bitcoin address to decimal and then truncate to 8 digits for this purpose? I understand that truncating the number in some way only increases the likelihood for collisions… however, would this still be practical or could the malware generate a rogue bitcoin address that would produce the same 8 digits of the legitimate bitcoin address?

Introduction. Bitcoins have been around since 2008 but have only began gaining attention in September 2011.
