Bitcoin and blockchain technology company Blockchain has raised $40 million in its second round of funding
This is the company behind online bitcoin wallet Blockchain.info. While providing convenience to average user, which may speed up the mainstream adoption, the concept of online bitcoin wallet contradicts the basic principle of crypto currency- decentralization. It's more suitable for old fashioned Paypal or egold than crypto. If the company is breached or bankrupt, you will lose your "independent" and "anonymous" coins.
South Korean web-hosting firm Nayana has agreed to pay a $1m ransom to unlock computers frozen by hackers
The ransomware - known as Erebus - targeted computers running Microsoft Windows and was also modified so a variant would work against Linux-based systems.
It appears that Nayana entered into negotiations with the hackers, lowering the fee from $4.4m to less than $500,000 although at the last minute, the hackers doubled the negotiated amount to $1m.
They are believed to have encrypted data on 153 Linux servers and 3,400 customer websites.
Is Etherium going to replace Bitcoin?
Got dumps bro?
One of the best feedbacks and recognitions of my Hacking Point of Sale book came from Facebook messenger:
"Got dumps bro?"
To whom who are not familiar with carders' terminology: "dump" means a file with credit card account numbers, expiration dates, security codes, and/or full content of credit/debit card magnetic tracks stolen from merchants' point of sale systems. So dump is the "product" of any card data breach which can be monetized. Usually, dumps are sold on darknet marketplaces (and paid by bitcoins by the way). Normally, hackers who are behind the breach -- those who actually plan and conduct the attack and steal the card data -- do not use those cards by themselves but sale them in batches ("dumps") to other groups who are in charge of monetization. Those other groups produce fake plastic cards, use them to buy merchandise in brick and mortar stores (or sometimes online), and then sell them on eBay to get cash.
Just 9 cents below $3,000... Some people say it's a bubble. I think it's just people trust more and more in digital currency, which slowly but surly enters the payment mainstream.
