An anonymous reader quotes a report from Bleeping Computer: An unknown hacker has used a vulnerability in an Ethereum wallet client to steal over 153, 000 Ether, worth over $30 million dollars. The hack was possible due to a flaw in the Parity Ethereum client. The vulnerability allowed the hacker to exfiltrate funds from multi-sig wallets created with Parity clients 1.5 and later. Parity 1.5 was released on January 19, 2017. The attack took place around 19:00-20:00 UTC and was immediately spotted by Parity, a company founded by Gavin Wood, Ethereum’s founder. The company issued a security alert on its blog. The Ether stolen from Parity multi-sig accounts was transferred into this Ethereum wallet, currently holding 153, 017.021336727 Ether. Because Parity spotted the attack in time, a group named “The White Hat Group” used the same vulnerability to drain the rest of Ether stored in other Parity wallets that have not yet been stolen by the hacker. This money now resides in this Ethereum wallet. According to messages posted on Reddit and in a Gitter chat, The White Hat Group appears to be formed of security researchers and members of the Ethereum Project that have taken it into their own hands to secure funds in vulnerable wallets. Based on a message the group posted online, they plan to return the funds they took. Their wallet currently holds 377, 116.819319439311671493 Ether, which is over $76 million.

Hacker Steals $30 Million Worth of Ethereum From Parity Multi-Sig Wallets
mikeebbbd writes: As reported in the Los Angeles Daily News, during the current heatwave various officials swooped down on streets coated with an experimental light-gray sealer that makes the old asphalt into a “cool street” — and it works, with average temperature differences between coated streets and adjacent old asphalt around 10F. At a large parking lot, the temperature reduction was over 20F. If the material holds up and continues to meet other criteria, LA plans to use it on more pavement rehab projects, which could eventually make a difference in the heat island effect. The “CoolSeal” coating is apparently proprietary to a company named GuardTop LLC, costs $25-40K/mile, and lasts 5-7 years. At that price, it’s might not be used a lot, at least at first; typical slurry seals run $15-30K/mile. Read more of this story at Slashdot.

Bitcoin jumped more than 10 percent to an all-time high of $2, 752.07, more than twice its April 30 price of $1, 347.96 according to CoinDesk. The digital currency last traded near $2, 726. At Thursday’s record, Bitcoin has now gained more than 45 percent since last Thursday and more than 180 percent for the year so far. “There is no question that we are in the middle of a price frenzy, ” said Brian Kelly of BKCM, in a note to clients Thursday. “There will be a correction and it could be severe, but it’s unclear if that correction will start from current prices of $2700 or from some place much higher.” Read more of this story at Slashdot.
