A flaw in ostensibly untraceable cryptocurrency Monero, which has picked up steam as market leader Bitcoin has stumbled in value, may make it possible to trace transactions - and since the entire history of Monero is encoded in its blockchain in what is now known to be a semi-vulnerable method, transactions that happened years ago could potentially be analysed for information on the parties involved.

Despite periodic crashes in the cryptocurrency markets, digital currency keeps on moving out of its formerly niche space and affecting the real world. Bitcoin-mining operations are now set to gobble more electricity than domestic residential consumption in Iceland, major credit card providers are banning purchases, rumoured scams as well as proven ones are rampant, and though some regulation has already been forthcoming authorities are largely playing catch-up.
So you've heard about Bitcoin and maybe even invested a little cash into it, hoping that its price continues to skyrocket.

It's one thing to wake up and discover that you missed the boat on a cryptocurrency boom that's making a handful of people very wealthy. It's another thing to find out that your computer is making someone else rich while it gives you poor performance and jacks up your electricity bill. With the spread of cryptojacking, that infuriating scenario is happening to more people.
Over the weekend, a user on Twitter pointed out that two of Showtime's websites had a script running in the background that's used to hijack visitors' CPUs to mine cryptocurrency. Other users and outlets later confirmed that the code was present. Now it's gone, and Showtime refuses to answer questions.
This past weekend, the popular torrenting site The Pirate Bay caught some flak for testing out a new system that used visitors' CPU power to generate cryptocurrency profits for itself. This tactic has been around for years, but the high profile implementation signals that it's probably time to start blocking this crap. Here's how it's done.
When the WannaCry ransomware attack hit back in May, it was really good at causing chaos but not so great at generating ransom money. Some analysts said that the attackers were amateurish in their methods. If the people behind the malware are as clumsy as they seem, they should be worried, because they recently started moving what Bitcoin they did collect during a particularly perilous time for cyber criminals.
