Israeli Security Lab Using Electromagnetic Waves to Extract Private Keys

Published

Perhaps the most important role in security research is breaking security, and that’s what the researchers at Tel Aviv University’s Laboratory for Experimental Information Security are up to with their recent forays into electromagnetic attacks.

The new research resembles a more advanced and applicable version of earlier research done in Israel, discussed previously here at Hacked. Rather than simply being able to intercept keys being pressed and data being entered into the system, as researchers were able to do even with air-gapped computers months back, this new exploit will allow the researchers to actually figure out the private key of a decrypted file. Applied on a commercial scale, these techniques could nullify many forms of public/private key encryption in normal environments. But how does it work?

Using one of a few methods of interception, the devices the researchers have put together can pick up the electromagnetic signals being put off by the target computer and then decipher meaning from them. In the case of a file being decrypted, the researchers were able to detect changes that could only be attributed to the decrypting of the file, and then to extract the private key from there.

In one instance, they were able to disguise the monitoring device in a piece of bread. They call this one the PITA – Portable Instrument for Trace Acquisition. In another, the device relays the signals to a larger terminal, which then can make sense of the signals being dumped onto it.

Most forms of encryption rely on secrets being kept. An encrypted file is not encrypted if an unintended person knows how to access it; it’s just difficult to get to. Now that private keys, as well as regular keystrokes and virtually anything else a user does on a computer, can be intercepted, many people might begin to start considering what the future of computing looks like for them. If you can’t count on encryption to protect your privacy, and you can’t count on being offline to protect your data, is there any way to use computers without being compromised?

  1. Real Anti-Racist Action

    This is easy to work around. It is simple basic and cheep, physical shielding within a PC or around hard-drives to protect peoples privacy from the Zionist-supremacist. Copper is a great metal to use in this case.

      You mean like a Faraday cage?

        Yes basically, only a little stronger. Instead of the thickness of a plastic bag. I am talking the thickness of like construction paper.
        #1 graphite shielding would work the best. And it would be the thinnest.

        #2 I believe Copper would be the second best at protection.
        Manufacturers should just make this standard. It will raise the price about $4 per laptop.

          Or maybe you could put down the pipe and not worry that the Mossad is sitting outside your house waiting to steal your Bitcorns.

    I guess you could start introducing a noise algorithm, basically running meaningless computer cycles to mask the actual application’s execution. It’s a waste of CPU time but you’ve got to do what you’ve got to do.

Monero Price Analysis: XMR/USD Slips Below Crucial Daily Support Ahead of System Update

Published

on

  • Monero’s navitve token XMR is forced to breach a key area of support by the market bears.
  • XMR/USD was being support by an ascending trend line, running from 14th August.
  • The Monero foundation is scheduled for a routine network upgrade.

Monero Network Update

The Monero foundation is scheduled to update its network on 18th October, as a result this will be bringing a new hard fork to its token. They have been making it a routine process now, hard forking every six months. Their focus being on the likes of increased ring-size for more privacy, with large transactions and tweaking their proof of work algorithm.

In terms of this upgrade, the goal is to enhance efficiency and make some adjustments to the current proof of work algorithm. Ultimately, to make it resistant and curb the threat of ASIC mining. Developers at Monero will be implementing the new Bulletproofs protocol. This will see greater privacy, lower fees and faster verification. It will reduce transaction size by an estimated 80%.

Technical Review – Daily Chart

XMR/USD daily chart

XMR/USD slipped out to the downside from an ascending trend line. As a result, the market bears managed to push for a breach and daily close below on 7th October. The support had been running since 14th August, where the price hit a low of $76.739.  A retest has been seen and pressure is now gradually mounting on Monero’s XMR. In terms of support, the 50DMA has provided some initial comfort for now. Furthermore, the next major downside support is observed in a chunky demand area. This is seen tracking from $86 down to $76. Resistance will now be eyed at $116.550 area, underneath the breached ascending trend line. In proximity to the 100DMA, which may cause some difficulty for the bulls. Elsewhere, further to the north, resistance can be seen within the $125.000 territory. Finally, heavy supply is tracking from $140 up to $150.

Technical Review – 4-hour Chart

XMR/USD 4-hour chart

Despite the above-mentioned daily breakout from the supporting trend line, there is still some hope for XMR/USD in the near-term, because from looking at the 4-hour chart view, the price has been moving within a range-bound block. This narrowing area has been running since 26th September. Fortunately for the price, a fresh wave of selling pressure has been prevented for now.  The lower part of the mentioned range has proven to see some near-term support. Therefore, the protection has been observed from around $112 to the high $111 territory. Although, a breach of this area could see a fast fall back down to sub $100, last traded below here on 12th September. While further downside pressure could force a retreat back down to a firm demand zone. Eyes would be on $86-77 range for buying.

Monero Price Analysis: XMR/USD Bulls Cooking Up Big Potential Moves

Published

on

  • XMR/USD price action surprisingly this week has been generally muted.
  • Current price behavior looks more favorable to see upside surprises, rather than any heavy selling pressure.

The Monero price this trading week has been somewhat muted. This comes as quite a surprise given the recent updates from the foundation. The foundation introduced the Maleware Workgroup, a huge step in efforts to protect the Monero community. Elsewhere, the foundation was also finally able to patch the ongoing ‘burning bug’ issue, which was proving to be a big problem. Full details of both developments posted in previous Monero article.

Near-term Analysis (60-Minute Chart)

XMR/USD 60-minute chart

Looking at the 60-minute chart for XMR/USD, it is very much clear to see how tight the trading range is. The vast majority of price action, aside from a couple of spikes here and there, has been swinging between $117 down to $111. This behavior has been observed since the bull run seen on 19th September, which was then paired after 23rd September fall.

Daily Chart View

XMR/USD daily chart

Price action is being supported by an ascending trend line on the daily chart. This has been running from 13th August, proving its strength. XMR/USD is currently stuck in between the 100DMA ($116.795), which is seen above, and the 50DMA ($110.877) below.  The price has seen a bounce on several occasions in September, off the trend line.

Next Move for Monero

The above-mentioned tracking ascending trend line is going to be vital in Monero’s recovery. Market bulls will need comfort, in case of another failed break down of above chunky supply area. This is seen tracking from $140-$150. There were several occasions in July and one in September, where the bulls failed to break this down. On each time the price has come into contact with this territory, it has been hit pretty hard by the sellers.

XMR/USD daily view

A breakout to the upside from the mentioned supply, could see a fast move towards $170, where some resistance can be seen. The price most recently found difficulty within this area at the early part of June. Enough bullish momentum should see it clear this territory, with $200 being reclaimed to the upside. XMR/USD was last trading above $200 back on 21st May.

Looking to the downside, a breach in the ascending trend line to the downside, could be catastrophic. Sellers would likely pile in with a high amount of volatility, sending the price down to sub-$100. The next chunky demand area is seen down within the $90-75 range. XMR/USD traded within this zone on 14th August, where the market managed receive a firm bounce.

Crypto Market Development: South Korea’s National Policy Committee Chair Calls For ICO Legalization

Published

on

  • A member of South Korea’s governing Democratic party and the chairman of Korea’s National Policy Committee, Min Byung-Doo, is urging to ease the current regulations on Initial Coin Offerings (ICOs).
  • Min Byung-Doo wants to introduce necessary regulatory framework, allowing ICOs in the country.

Allow ICOs In South Korea

The South Korean National Policy Committee Chief, Min Byung-Doo, is calling for a regulatory framework to be explored. This would be to allow for Initial Coin Offerings (ICOs) to take place within the country. He stated that the current prohibiting of ICOs weakens the industry’s competitiveness appeal with foreign markets. Further boldly adding, this would be preventing growth.

In his statement at to lawmakers, Byung-Doo said, “We can see that the flow of investment is clearly changing compared to ICO and angel fundraising. The ICO has raised $1.7 billion for Telegram and $4 billion for Block.One, it is getting bigger and bigger.”

Further in the statement, Min Byung-Doo said, “Let the government, the National Assembly and the blockchain association quickly create a working group to block fraud, speculation, money laundering and develop the block-chain industry,”. However, he acknowledged the government’s reluctance to create the needed framework.

In September 2017, the Financial Services Commission in South Korea announced a ban on ICOs. The law has not yet been enacted.

Crypto Market Reaction

A lack of reaction has been observed for now, despite this determination to help further legitimize the digital currency market in South Korea. Crypto market developments in the country are always watched very carefully. This is given their large crypto market participation. It was reported in December 2017 that South Korea accounted for as much as 17% of all Ethereum trades occurring in cryptocurrency markets.

Market Reactions To South Korean Related News

Ripple (XRP) crashed in January, following CoinMarketCap’s decision to remove XRP price data from Korean exchange desks. This as a result largely brought down the total average.

XRP/USD Coinmarketcap update triggered drop

On 11th January, Korean crypto exchange Coinrail was hacked, and over $40 million in tokens were stolen. Bitcoin initially dropped over 11% on this.

BTC/USD Coinrail hack triggered drop

One final example, UPbit, a South Korean exchange, was investigated by authorities for illicitly moving customer funds to the account of its executives. Bitcoin initially dropped over 7% on the news.

BTC/USD UPbit investigation triggered drop

Given the above mentioned, one should keep an eye on any developments coming out of South Korea, for the foreseeable future.
