Hackers Hijacking CPUs to Mine Cryptocurrency Have Now Invaded YouTube Ads

Posted on by

As Ars Technica first reported on Friday, users on social media started complaining earlier this week that YouTube ads were triggering their anti-virus software. Specifically, the software was recognizing a script from a service called CoinHive. The script was originally released as a sort of altruistic idea that would allow sites to make a little extra income by putting a visitor’s CPU processing power to use by mining a cryptocurrency called Monero. This could be used ethically as long as a site notifies its visitors of what’s happening and doesn’t get so greedy with the CPU usage that it crashes a visitor’s computer. In the case of YouTube’s ads running the script, they were reportedly using up to 80 percent of the CPU and neither YouTube nor the user were told what was happening.

Thanks to “consent” buried deep in sales agreements, car manufacturers are tracking tens of millions of US and EU cars

Posted on by

Millions of new cars sold in the US and Europe are “connected,” having some mechanism for exchanging data with their manufacturers after the cars are sold; these cars stream or batch-upload location data and other telemetry to their manufacturers, who argue that they are allowed to do virtually anything they want with this data, thanks to the “explicit consent” of the car owners — who signed a lengthy contract at purchase time that contained a vague and misleading clause deep in its fine-print.

Car manufacturers are mostly warehousing this data (leaving it vulnerable to leaks and breaches, search-warrants, government hacking and unethical employee snooping), and can’t articulate why they’re saving it or how they use it.

Much of this data ends up in “marketplaces” where data-sets from multiple auto-makers are merged, made uniform, and given identifiers that allow them to be cross-referenced with the massive corporate data-sets that already exist, and then offered on the open market to any bidder.

Researchers find a way to link TOR / Silk Road BTC expenditure to people using two datasets

Posted on by

To do so, the Qatari researchers first collected dozens of bitcoin addresses used for donations and dealmaking by websites protected by the anonymity software Tor, run by everyone from WikiLeaks to the now-defunct Silk Road. Then they scraped thousands of more widely visible bitcoin addresses from the public accounts of users on Twitter and the popular bitcoin forum Bitcoin Talk.

By merely searching for direct links between those two sets of addresses in the blockchain, they found more than 125 transactions made to those dark web sites’ accounts—very likely with the intention of preserving the senders’ anonymity—that they could easily link to public accounts. Among those, 46 were donations to WikiLeaks. More disturbingly, 22 were payments to the Silk Road. Though they don’t reveal many personal details of those 22 individuals, the researchers say that some had publicly revealed their locations, ages, genders, email addresses, or even full names. (One user who fully identified himself was only a teenager at the time of the transactions.) And the 18 people whose Silk Road transactions were linked to Bitcoin Talk may be particularly vulnerable, since that forum has previously responded to subpoeanas demanding that it unmask a user’s registration details or private messages. “You have irrefutable evidence mapping this profile to this hidden service,” says Yazan Boshmaf, another of the study’s authors.
