Infosec writer, podcaster and community builder, content strategist and senior writer at Sophos. I like the article, I do not like the headline. I think it is wrong. I hate ads-contaminated Websites. Script-based Crypto-mining might be an alternative to paid ads.
I would definitely prefer an ad-free Website Crypto-mining with some defined percentage of my CPU against a standard Website full with ads today. Yes, we are not there. We would need Crypto-mining services paying Websites, while the Website hosts their Crypto-miner. And get rid of the ads. Of course we need the user agreement, similar to accepting proxies today. But the headline somewhat excludes this excellent opportunity to get what I think could be a better Cyberspace. We absolutely understand the idea that cryptomining programs can be a viable alternative income source to ads.
However, this is a case where Sophos had to make a decision to protect its customers. For us, the key is simple: The user must be asked for permission before their computers can be used in this manner. Anything else is a deception and amounts to theft of resources.
The key going forward is that cryptominers be used in an open and honest way.
