More Than 4,000 Government Websites Infected With Covert Cryptocurrency Miner
from the whoops-a-daisy dept
The rise of cryptocurrency mining software like Coinhive has been a decidedly double-edged sword. While many websites have begun exploring cryptocurrency mining as a way to generate some additional revenue, several have run into problems if they fail to warn visitors that their CPU cycles are being co-opted in such a fashion. That has resulted in numerous websites like The Pirate Bay being forced to back away from the software after poor implementation (and zero transparency) resulted in frustrated users who say the software gobbled upwards of 85% of their available CPU processing power without their knowledge or consent.
But websites that don't inform users this mining is happening are just one part of an emerging problem. Hackers have also taken to using malware to embed the mining software into websites whose owners aren't aware that their sites have been hijacked to make somebody else an extra buck. Politifact was one of several websites that recently had to admit its website was compromised with cryptocurrency-mining malware without their knowledge. Showtime was also forced to acknowledge (barely) that websites on two different Showtime domains had been compromised and infected with Coinhive-embedded malware.
While Bloomberg this week proclaimed that governments should really get behind this whole cryptocurrency mining thing, the reality is that numerous governments already have -- just not in the way they might have intended. Security researcher Scott Helme this week discovered that more than 4,000 U.S. and UK government websites -- including the US court system website -- have been infected with cryptocurrency mining malware, a number that's sure to only balloon.
As Helme notes, attackers don't need to even attack each website individually, as they've found a way to compromise shared resources like Text Help, whose modified script files were then loaded by thousands of websites at a pop:
Hey @texthelp you've been compromised, you need to address this ASAP. Their site also has the crypto miner running: pic.twitter.com/fl0U9ssZRr

Fortunately this attack isn't particularly hard to neutralize, with a tiny modification to the share script being able to nip similar, future attacks in the bud. But Helme also notes that this entire kerfuffle could have been substantially worse:
The more I think about this the worse it becomes. Attackers had arbitrary script injection on thousands of sites including many NHS websites here in England. Just stop and think for a few moments about what exactly they could have done with that capability... 😱

Ultimately it seems like these kinds of attacks should be easy to avoid once site administrators and governments wise up to the rising threat. That said, reports by cybersecurity firm CrowdStrike have suggested things will get a little worse before they get better. Again though, the malware angle is just one conversation we need to be having. How sites can responsibly and transparently implement miners as an alternative revenue stream is going to be something we'll be talking about for a while, as Salon made evident this week as the first website to offer the option as an alternative to traditional advertising.
