According to a report in Reuters, U.S. security professionals and researchers have devised and demonstrated a hack which proves that standard equipment inside computers, printers and millions of other devices can be hijacked to transmit data via sound waves.

While spy agencies and pioneers in cryptography have looked into irreverent and arcane ways for clandestine activity for decades, the researchers of today, led by Ang Cui at Red Balloon security, demonstrated the hijack to a group of assembled reporters at the annual Black Hat security conference in Las Vegas.

How it Works

Cui confirmed that he would release the “proof-of-concept” code after the conference, ensuring that other researchers and hackers (white-hat and/or malicious attackers) get to test and build on his team’s work.

Here’s how the hijack works:

  • The exploit overtakes control of the actual physical prongs on general input/output circuits within the computer.
  • After establishing control, the circuits are vibrated at a frequency chosen by the researchers. This leaves vibrations to be audible or inaudible, depending on the frequency.
  • These vibrations can then be picked up with a simple AM radio antenna that’s within a short radius of the device.

Dubbed “Funtenna” by Cui, the makeshift transmitting antenna has the means to act as an additional channel that would be hard to detect. This is fundamentally due to the lack of traffic logs or any record of data being transmitted.

Quite simply, hackers would simply require an antenna situated within the vicinity of the machine to pick up on the sound waves. They’d also need to find a way to dismantle the targeted machine and convert the required data to the format suitable for transmission, Cui added.

Cui and his team of researchers have worked on the “Funtenna” for the past two years, proving that modern devices can be manipulated and hijacked in ways that are unheard of. With devices and gadgets becoming more and more complex, attackers will inevitably find more ways to increase their advantage in the battle for cybersecurity.

    I’m beginning to suspect that the real reason why overarching security and privacy research and standards are falling way behind the ability of state and criminal hackers to innovate is because exploits like this are not original, but only represent the tip of the iceberg of state surveillance and snooping’s toolbox of tricks.

    In other words, it’s not in Obama’s (for example) interest to call for a national body to systematically collect exploits and coordinate commercial standards of hardware and software specifications that would receive a stamp of certification on any instance of system or device that meets or exceeds standards.

    Thus: How does the NSA (or the Red Army), or Mossad, or FSB spy on you if your box is proofed against the tricks you implement because the governments deliberately spilled, and shared, the beans?

Uber Is Paying Hackers to Keep Quiet

Published

on

Uber Technologies Inc. has reportedly paid hackers to delete scores of private data stolen from the company in a security breach that was concealed for over a year. The revelation provides further confirmation that, when it comes to cyber security, crime does pay.

Massive Data Breach

According to Bloomberg Technology, hackers retrieved the personal data of 57 million Uber customers and drivers at some point last year. Nobody heard about it because the rideshare company paid the hackers $100,000 to keep quiet. A purge at the front office of Uber also ensured that the massive cyber breach was kept under wraps.

The compromised data was from October 2016 and included the names, phone numbers and addressed of 50 million Uber riders globally. About seven million drivers had their personal information accessed as well.

At the time of the cyber attack, Uber was inundated with a slew of legal issues stemming from alleged privacy violations. Rather than shine even more negative spotlight on the company, Uber executives decided to pay hackers to stay quiet.

“None of this should have happened, and I will not make excuses for it,” Dara Khosrowshahi, who took over as CEO in September, said in a statement that was published by Bloomberg. “We are changing the way we do business.”

Hackers have done a masterful job infiltrating companies and governments in recent years. As a reminder, recent cyber attacks levied against Yahoo!, Target Corp and Equifax Inc. dwarf Uber’s 57 million compromised accounts.

Various reports indicate that cyber attacks are bleeding the global economy dry. One report, issued by the World Economic Forum, suggests that cyber crime cost the world economy $445 billion in 2016. If cyber crime were its own market cap, it would exceed Microsoft Inc., Facebook Inc. and ExxonMobil Corp

The Fall of Uber?

Uber revolutionized the ride-hailing business over the span of seven years by giving more power to the consumer. Several missteps later, the company finds itself in legal hot water, with its future appearing less certain than it did just one year ago.

The rideshare company faces at least five U.S. probes ranging from bribes to illicit software and right up to unethical pricing schemes. According to another Bloomberg report, Uber is under investigation for violating price transparency regulations, not to mention the alleged theft of documents for Google’s autonomous cars.

Some governments are sensing weakness in the ride-hailing service, and are moving toward banning the Uber app entirely. London is the most prominent example of a city that has taken definitive steps to outlaw the service over a “lack of corporate responsibility.”

Even with its legal troubles, Uber is a revolutionary technology that has influenced a bevy of other innovations aimed at improving the human experience.

The Pirate Bay is Hijacking PCs to Stealth-Mine Cryptocurrency

Published

on

For the second time in as many months, The Pirate Bay has been caught mining cryptocurrency on your computer without consent. The torrent platform was actually test-driving cryptocurrency mining in your browser – no doubt a lucrative revenue stream.

// -- Discuss and ask questions in our community on Workplace.

The Pirates Are At It Again

The Pirate Bay has been caught using software called Coinhive, a JavaScript library that essentially serves as a cryptocurrency miner. It basically connects to visitors’ computers to mine Monero, one of the world’s most profitable cryptocurrencies.

The news was later confirmed by Bleeping Computer, which reported that,”The Pirate Bay, the internet’s largest torrent portal, is back at running a cryptocurrency miner after it previously ran a short test in mid-September.”

Estimates indicate that the scheme has earned the pirates a total of $43,000 over a three-week period.

Users had no way to opt their computers out of being test-driven by the torrent network. Back in September, The Pirate Bay got away by telling people it was just a test. The site’s owners cannot use the same excuse this time around.

CoinHive advises websites to let their visitors  know their browser is being used to mine cryptocurrency.

“We’re a bit saddened to see that some of our customers integrate CoinHive into their pages without disclosing to their users what’s going on, let alone asking for their permission,” the company said.

The good news is most ad-blockers and antivirus programs will block CoinHive, given its recent abuses. That means not all visitors of The Pirate Pay were being used as a conduit for mining Monero.

Monero Joins Global Crypto Rally

The value of Monero (XMR) shot up nearly 8% on Friday, and was last seen trading at $94.17. With more than 15.2 million XMR tokens in circulation, the total market cap for Monero is $1.4 billion, according to CoinMarketCap. That’s enough for ninth on the global cryptocurrency list.

Twelve cryptos have now crossed the $1 billion valuation mark. A handful of others have made their way north of $500 million.

Ethereum Notches Two-Month High as Bitcoin Offspring Triggers Volatility

Published

on

Digital currency Ethereum climbed to a two-month high on Monday, taking some of the heat off Bitcoin and Bitcoin Cash, which have slumped since the weekend.

// -- Discuss and ask questions in our community on Workplace.

Ethereum Forges Higher Path

Concerns over Bitcoin created a favourable tailwind for Ethereum (ETH/USD), which is the world’s No. 2 digital currency by total assets. Ether’s price topped $340.00 on Monday and later settled at $323.54. That was the highest since June 20.

At its peak, ether was up 10% on the day and 70% for the month of August.

The ETH/USD was last down 2.2% at $315.02, according to Bitfinex. Prices are due for a brisk recovery, based on the daily momentum indicators.

Fractured Bitcoin Community

Bitcoin and its offshoot, Bitcoin Cash, retreated on Monday following a volatile weekend. The BTC/USD slumped at the start of the week and was down more than 3% on Tuesday, with prices falling below $3,900.00. Just last week, Bitcoin was trading at new records near $4,500.00.

Bitcoin Cash, which emerged after the Aug. 1 hard fork, climbed to new records on Saturday, but has been in free-fall ever since. The BTH was down another 20% on Tuesday to $594.49, according to CoinMarketCap. Its total market value has dropped by several billion over the past two days.

Analysts say that a “fractured” Bitcoin community has made Ethereum a more attractive bet this week. The ether token has shown remarkable poise over the past seven days, despite trading well shy of a new record.

Other drivers behind Ethereum’s advance are steady demand from South Korean investors and growing confidence in a smooth upgrade for the the ETH network. The upgrade, which has been dubbed “Metropolis,” is expected in the next several weeks. Its key benefits include tighter transaction privacy and greater efficiency.

Ethereum Prices Unaffected by ICO Heist

Fin-tech developer Enigma was on the receiving end of a cyber-heist on Monday after hackers took over the company’s website, mailing list and instant messaging platforms. The hack occurred three weeks before Enigma’s planned Initial Coin Offering (ICO) for September 11.

In addition to defacing the company’s website, the hackers pushed a special “pre-sale” ahead of the ICO. While many users realized it was a scam, 1,492 ether tokens – valued at $495,000 – were directed into the hackers’ cryptocurrency wallet by unsuspecting backers.

The irony in all this is that Engima is a cryptography company that prides itself on top-notch security protocols. The company issued a statement that its servers had not been compromised.
