Cryptocurrency Mining

Sponsored by:. If you've landed on this page because you saw a strange message on a completely different website then followed a link to here, drop a note to the site owner and let them know what happened. If, on the other hand, you're on this page because you're interested in reading about the illicit use of cryptomining on compromised websites and how through fortuitous circumstances, I now own coinhive.

You know how people don't like ads? Yeah, me either at least not the spammy tracky ones that invade both your privacy and your bandwidth , but I also like free content on the web and therein lies the rub; how do content producers monetise their work if they can't put ads on pages? That's a link to the last snapshotted version on archive. The website is dead. However, it's now owned by me and it's just sitting there doing pretty much nothing other than serving a little bit of JavaScript.

I'll come back to that shortly, let's return to the business model of Coinhive:. So, instead of serving ads you put a JavaScript based cryptominer on your victi They're paying for the CPU cycles to put money into your pocket - ingenious! But there were two massive problems with this and the first one is probably obvious: it's a sleazy business model that usually unknowingly exploits people's electricity bills for the personal gain of the site operator.

It might only be exploiting them a little bit how much power can an in-browser JS cryptominer really draw? The second problem is that due to the anonymous nature of cryptocurrency, every hacker and their dog wanted to put Coinhive on any sites they were able to run their own arbitrary JavaScript on. In that blog post I included the code Scott Helme had de-obfuscated which showed a very simple bit of JavaScript, really just the inclusion of a. And that's all an attacker needed to do - include the Coinhive JS, add their key and if they wished, toggle a few configurations.

That's it, job done, instant crypto! And then Coinhive was gone. The site disappeared and the domain stopped resolving. Every site that had Coinhive running on it, either by the design of the site owner or at the whim of a cryptojacker, stopped mining Monero. However, it was still making requests to the domain but without the name resolving anywhere, the only signs of Coinhive being gone were errors in the browser's developer tools. In May , I obtained both the primary coinhive.

I'm not sure how much the person who made these available to me wants to share so the only thing I'll say for now is that they were provided to me for free to do something useful with. I stood up a website and just logged requests. Every request resulted in a , but every request also went into a standard Azure App Service log. And that's where things got a lot more interesting. Firstly, the high-level stats and as I was routing through Cloudflare, it was super easy to look at the volume of requests first:.

That's a substantial number of requests; peaking at 3. But the number that really impressed me if "impressed" is the right word here More than 2 years after Coinhive was gone and the miner is still embedded in enough places to be serving more than k unique visitors per day. I wonder where they're all coming from? Just for context, Have I Been Pwned which sees about k visitors per day has a geographical distribution as follows:. I'm loath to draw stereotypical conclusions about the association of hackers to Russia and China, but it's a bit inescapable here.

Later on, when I analysed the various URLs that were injecting Coinhive, there was anecdotally a strong presence of Russian and Chinese websites. The JS file being requested is how Coinhive was usually embedded in a site. The IP is Cloudflare's remember, they're a reverse proxy so it's their IP the website receives and the response code is as there was no resource to return.

The referrer is the interesting one because this tells us where the script was requested from, in this case a website at lookedon. A quick glance at that site at the time of writing and yeah, that's a cryptominer in the HTML source:. It's only 21 minutes long and it gets straight to the point:. If you want to go much deeper, have a good read through this. Incidentally, I've been in touch with Hugo and we're discussing how to best use the data I'm logging for both research and defensive purposes.

I pulled down several days of logs beginning and imported them into a DB where I could analyse things more easily 8. I looked firstly at the content that was being requested all subsequent figures exclude the cnhv. The prevalence of the JavaScript miners is no surprise, and the Delft guys talk about the role of the WebAssembly. There were references to WASM in the original Coinhive script , but of course nobody has been loading that for quite some time so I can only assume it's being embedded by other means.

The logs don't have a referrer on any of the WASM entries either so it's not clear where the requests are originating from:. Next up is the referrer, but due to there being many different paths on the same site serving the miner, I grouped by host and reported on that:. I found more than 41k unique domains in the referrer header.

That's many tens of thousands of websites still attempting to embed Coinhive. Taking a look at webtruyenonline. Not in the page source, not requested from a downstream dependency and not on other deeper links in the referrers either. Looking closer at the log entries, a pattern emerged with the user agents, so I filtered those out and grouped them:. They're all mobile devices.

Is it tailoring the response based on the location of the requesting IP? Hugo also had some thoughts on this one:. Securing the transport layer isn't just about protecting sensitive information, it's also about protecting the integrity of the content and assuming Hugo is right here, this is a beautiful demonstration of the necessity of HTTPS everywhere.

The next host name at aahora. I don't intend to keep going through the top hits, the point is that the presence of requests in the logs doesn't always map cleanly to the presence of Coinhive on the site in the referrer. I can think of a variety of reasons for this but suffice to say there were still a heap of sites attempting to embed a cryptominer in the browser.

There was just one more thing I was interested in - what can we tell about concerted cryptojacking campaigns based on the data?

I mean how many of these log entries were from sites running the same Coinhive key which would indicate the same actor behind each site? So, I wrangled up a little crawler script and started scraping each unique site looking for the presence of Coinhive. It's a basic one it merely looks for a Coinhive key in the HTML source so misses keys embedded in another JS file or an iframe , but it's sufficient for my requirements here.

I crawled the first k URIs based on the most prevalent in the logs, pulled back the keys and recorded the number of unique URIs and host names they appeared on. I found over 3k unique keys, here's the top Doing a bit of Googling for the keys, I found 2 interesting things and the first one relates to the second key "FgW Well, that supports Hugo's earlier thesis. As prevalent as that key may be having appeared on unique hosts, it could just be a single infected router.

In this particular case there was a heavy bias towards "sahara" domains. These relate to Subarta Roy , a name I only knew after recently watching the Netflix series Bad Boy Billionaires , of which he is apparently one. Is there someone within the corrupt billionaires org running an infected router that's cryptojacking all their non-secure requests? I suspect that's just one of many curious mysteries within the data set. That third key - "w9W It's hard to draw any conclusion other than that there remains a large number of compromised websites out there hosting Coinhive even now that Coinhive is dead.

They're no longer mining crypto, of course, however these sites are still embedding JavaScript on them from a domain I control so The modal is embedded directly from script served by the site I stood up. The link goes through to this blog post and the message can be easily dismissed by folks who just want to browse the site. I thought carefully about this approach; did I really want to modify other people's websites? I want site owners to know there's a high likelihood they've been compromised, problem is how do you do that otherwise when we're talking about tens of thousands of sites?

I've done enough disclosures over enough years to know that even doing this once is painful, but if I was to write just a little bit of JavaScript instead Oh - and while we're here let's just let that sink in for a moment: I can now run whatever JavaScript I want on a huge number of websites. So, what could I do with JavaScript? I could change where forms post to, add a key logger, modify the DOM, make external requests, redirect to a malicious file and all sorts of other very nasty things.

That's the power you hand over when you embed someone else's JS in your own site and that's precisely why we have subresource integrity.

I linked earlier to my post on SRI as it related to the Browsealoud incident and this situation right here is as good a demonstration as ever as to why verifying the integrity of external assets is so important. So, what's the fix? Well, it depends, and to answer that we need to go back to the preso from Delft uni guys, in particular this slide:.

If the miner is owner-initiated then firstly, shame on them, and secondly, just remove it. If it was their conscious decision to embed the miner in the first place, they can then remove it of their own free volition.

But much more prevalent than this is malicious activity, in fact it accounts for the vast majority of instances once you consider both third-party software compromises and compromises of the primary website itself:.

The answer here is twofold, and the first part is obviously to either remove the compromised code or third-party library then, of course, fix the underlying vulnerability i.

But we also have the technology to ensure the crypto code could never have run on the site in the first place, and that brings me back to CSPs. Let's take one of the most commonly occurring websites in my logs, lookedon. This service enables you to "find interesting pictures" and like most modern web sites, it embeds all sorts of content types from different places by design.

For example, there's a bunch of the following:. There are other content types loaded from other locations but for the sake of simplicity, let's just work with this list for now. Using a content security policy, I can define the content types and locations the browser is allowed to make requests to and anything that deviates from that known good state is blocked. Here's what a policy for the 4 points above would look like:. The CSP is then returned as a response header for any pages on the website.

Cryptocurrency mining is the process where specialized computers , also known as nodes or mining rigs, validate blockchain transactions for a specific cryptocoin and, in turn, receive a mining reward for their computational effort. Rigs use the latest processors e. Using standard personal computers for mining is not advisable as most lack the computational power to handle mining-level processing. With a fleet of nodes or a pool, a group of individual miners can combine computational effort, dubbed hash rates, to win block rewards and split the earnings according to contribution. Blockchains require a protocol for achieving a decentralized consensus to verify the integrity of new blocks, and in crypto mining, this consensus mechanism is proof-of-work PoW. By contributing computational effort to validating transactions, miners receive a predefined amount of the coin for their proof of work.
