$300m in cryptocurrency accidentally stolen and lost forever due to bug | Technology




More than $300m of cryptocurrency has been lost after a series of bugs in a popular digital wallet service led one curious developer to accidentally take control of and then lock up the funds.

Unlike most cryptocurrency hacks, however, the money wasn’t deliberately taken: it was effectively destroyed by accident. The lost money was in the form of Ether, the tradable currency that fuels the Ethereum distributed app platform, and was kept in digital multi-signature wallets built by a developer called Parity. These wallets require more than one user to enter their key before funds can be transferred.

On Tuesday Parity revealed that, while fixing a bug that let hackers steal $32m out of few multi-signature wallets, it had inadvertently introduced a new flaw into its systems that allowed one user to become the sole owner of every single multi-signature wallet.

The user, “devops199”, triggered the flaw apparently by accident. When they realised what they had done, they attempted to undo the damage by deleting the code which had transferred ownership of the funds. Rather than returning the money, however, that simply locked all the funds in those multisignature wallets permanently, with no way to access them.

“This means that currently no funds can be moved out of the multi-sig wallets,” Parity says in a security advisory.

Effectively, a user accidentally stole hundreds of wallets simultaneously, and then set them on fire in a panic while trying to give them back.

“We are analysing the situation and will release an update with further details shortly,” Parity told users.

Hard fork

Some are pushing for a “hard fork” of Ethereum, which would undo the damage by effectively asking 51% of the currency’s users to agree to pretend that it had never happened in the first place. That would require a change to the code that controls ethereum, and then that change to be adopted by the majority of the user base. The risk is that some of the community refuses to accept the change, resulting in a split into two parallel groups.

Such an act isn’t unheard of: another hack, two years ago, of an Ethereum app called the DAO resulted in $150m being stolen. The hard fork was successful then, but the money stolen represented a much larger portion of the entire Ethereum market than the $300m lost to Parity.

The lost $300m follows the discovery of bug in July that led to the theft of $32m in ether from just three multisignature wallets. A marathon coding and hacking effort was required to secure another $208m against theft. Patching that bug led to the flaw in Parity’s system that devops199 triggered by accident.

Ethereum has rapidly become the second most important cryptocurrency, after Bitcoin, with its price increasing more than 2,500% over the past year. One token of Ether is now worth a little over $285, up from $8 in January.

LG G7 ThinQ Is Now Available In the US for $750



LG waited longer than normal to announce its big 2018 flagship phone, but it finally took the wraps off the LG G7 ThinQ a few weeks ago. Today, the phone is available for purchase on most US carriers. While LG has had trouble competing with the likes of Samsung, it’s still targeting the same premium space. Although, it’s got an iPhone-style screen notch now. That’s what consumers want, right?

The LG G7 ThinQ is the epitome of all things 2018 in smartphone design. It has a glass back, dual cameras, and a display notch that isn’t done particularly well. The missing bit of screen provides a place for the camera, earpiece, and some other sensors. It does seem a little excessively large for how compact these components are, though. In addition, the G7 has a “chin” at the bottom with a larger bezel than the top and bottom. This asymmetric look isn’t as striking as the iPhone X it imitates. The 6.1-inch 1440p display is also an OLED, which lacks the vibrancy of modern OLED panels.

Inside, this phone has all the current flagship hardware you’d expect with a Snapdragon 845, 64GB of storage, and 4GB of RAM. Unlike many other current smartphones, the company has opted to keep the headphone jack for the G7 ThinQ. LG also touts the G7’s unique speaker design that uses the entire chassis as a resonator to boost sound output.

You may be wondering about the name — specifically the “ThinQ” bit. Well, that’s LG’s expanded brand for all its AI technologies. What that means for the G7 is that there’s an AI mode in the camera that looks for objects it can identify and offers possible filters. It’s not very accurate or useful, but LG didn’t even develop any AI software or hardware for this phone. It just licensed a machine vision library from a third-party.

The LG G7 ThinQ is available from all major carriers in the US except AT&T. Apparently, AT&T chose to sell the LG V35 instead of the G7. This marks the third variant of the V30 that LG has sold since it debuted last year. At other carriers, the G7 ThinQ will run you $750, give or take a few dollars. Carriers offer payment plans to split the cost over two years. It will launch on Google’s Project Fi soon, as well. If you don’t want to go through carriers, the phone is also available from Amazon.

Google Doodle honors ‘Prince of Mathematicians’ Johann Carl Friedrich Gauss






Maths is the latest to receive the Google Doodle homage.

Johann Carl Friedrich Gauss, otherwise known as “The Prince of Mathematicians”, made instrumental contributions to number theory, algebra, geophysics, mechanics and statistics.

Gauss was born on April 30 in 1777 in Brunswick, a city in the north of Germany, near Wolfsburg. Despite poor working-class parents and an illiterate mother, Gauss was a child prodigy, believed to have been able to add up every number from 1 to 100 at 8-years-old.

One of his first major equations was working out his date of birth, which his mother hadn’t recorded. He used the only information she had: that it was a Wednesday, eight days before an Easter holiday.

At university when he was 19, Gauss discovered a heptadecagon, or a 17-sided polygon. He requested that a regular heptadecagon be inscribed on his tombstone, but it was too difficult for the stonemason, who said it would just look like a circle.

And remember your prime numbers? That year Gauss was involved with proving the prime number theorem, helping understand how prime numbers are distributed among the integers, or whole numbers.

Again the same year, a productive one for Gauss, he discovered the quadratic reciprocity law, which allows mathematicians to determine the solvability of any quadratic equation in modular arithmetic.

At 24, Gauss’ work on number theory, which he completed when he was 21, was published as a textbook. Not only did it involve his original work, but it reconciled that of other mathematicians. It would be considered his magnum opus and had an extraordinary impact on the field.

Oh, and add to those achievements a discovery in astronomy — in the same year, 1801, Gauss calculated the orbit of an asteroid called Ceres.

After a much-accomplished life, Gauss died aged 77 on Feb. 23, 1855.
