How does one actually block this?
When I visit for example https://coinhive.com/ and push the button "Start Mining" the CPU goes up to 100%.
Solved! Go to Solution.
I have found how to block this in the AntiSpyware profile.
It appears that for many of the AntiSpyware actions the default setting is alert. Even for some of the critical ones.
Not sure why this is but I will play around with the settings to see if this can be set to block.
Unfortunately there is an additional challange.
This site is SSL encrypted and although there is SSL decryption enabled on the firewall, the site itself is classified as "Financial Services" which is excluded from SSL decryption due to regulations.
So if I find the solution on how to decrypt the site, I should be able to block this.
so do you block it by your spyware filters or it is blocked by PANDB filter?
because to me it is still unclear how Palo blocks it (if it does)
I'm really surprised this is classified as low severity? This can get onto servers and spike CPU to 100% to take down applications.
Also, I don't think these mining websites should be listed as
Auctions?? coinhive malware was going around injecting user's PCs......
They're saying minexmr.com is malware because it was recently used in a malware mining injection incident, however couldn't you use any miner website with the injection?
Needs to be a new URL PAN-DB category for Cryptocurrency, in my opinon.
Clean this up PAN, this is going to be one of the biggest issues in 2018 against networks in my opinion. Make this a priority.
I feel that the Palo Alto Networks response to crypto jacking is disappointing. There is a security reaseacher that is actively tracking cryptomining domains and (as of now) is maintaining up-to-date lists of these domains. You can add the first two lists "all domains" and "all optional domains" to an External Dynamic List and then edit your exsiting Anti-Spyware policies to sinkhole those domains. As of this post, there are 3,898 domains in those two lists (combined).
Thanks @kalakai for the links. Good stuff.
What is the advantage over using a sinkhole over just using a DBL and setting the rule to block completely?
