Bitcoin Forum

So much data has been stolen from so many disparate sources, and it seems a number of websites or schemes pop up with no other real purpose other than to collect data on users. Data has been taken from multiple exchanges - data on tens of thousands of users. If a reasonably funded hacking ground is collating and data mining just a fraction of this, they could zero in on the community for all sorts of nefarious campaigns.

I'm growing more wary, not only of leaving my coins on central exchanges (Bitfinex, Polo, you name it), but even signing up for a new gambling site, or enrolling in new services with little to no track record.

Have you seen evidence that one or more hacking groups is data mining our community, or compiling community-wide data in preparation for some future attack vectors?

Their window of opportunity to hack centralized exchanges is likely closing - it should close eventually - and they must be looking toward the time when their attacks will have to be along another vector.

That's an optimistic viewpoint!

Unfortunately, centralized providers are here to stay until there is some very clever on/off ramp to claim fiat.

As for your main point, about the hackers...sure, there are always nefarious sources at work. But there are probably far more hackers gathering meta data on identities with your information from the major banks and major credit cards, which all have experienced major leaks recently.

The most serious security problem right now is ransomware.
