Intel Core X AMD EPYC Ethereum Core i9-7900X Cryptocurrency Vega home News Intel AMT Vulnerability’s Hijacking Horrors Revealed By Whitepaper Intel last week finally got around to plugging a security hole that existed for decades affecting platforms with Active Management Technology (AMT), Intel Standard Manageability (ISM), and Small Business Technology (SBT).Consumer systems were untouched by this bug, but otherwise systems dating all the way back to Nehalem (2008) were potentially at risk.As it turns out, the flaw was more serious than initially thought.First, the good news.Intel says it has implemented and validated a firmware update to address the problem and is collaborating with computer makers to roll it out quickly and smoothly.It is ultimately up to OEMs to provide the critical update to customers, and to that end Intel says it expects computer makers to make updates available beginning this week (and continuing thereafter).Until those updates arrive, Intel recommends that IT admins and individuals download and run the company's discovery tool to determine if a system is potentially at risk.

If it discovers a vulnerability or is unable to determine if one exists, Intel recommends the following: Until firmware updates are available, systems administrators can take the mitigation steps detailed in the mitigation guide published under our security advisory.Please note that capabilities and features provided by AMT, ISM and SBT will be made unavailable by these mitigations.Consumers or others who need support securing vulnerable systems can contact Intel Customer Support.To contact Intel Customer Support by phone in the U.S., Canada or Latin America, call (916) 377-7000.Europe, Middle East and Africa support phone numbers can be found on Intel’s support website.Asia Pacific support phone numbers can be found on Intel’s Asia support site.So there you go, Intel is on top of things.The bad news is that the threat is more serious than originally thought.The affected services are what IT admins use to configure systems remotely, even if there is not an operating system installed.

That is part of what makes this exploit so scary, though it is not the only thing.Security outfit Embedi is the one that brought all of this to attention and it has now released a whitepaper outlining the technical details.One of the things the company notes is that the AMT vulnerability is the first of its kind and that it allows an attacker to gain full control over business PCs even if they are turned off (but still plugged into an outlet)."By nature, the Intel AMT exploitation bypasses authentication.In other words, an attacker may now credentials and still be able to use the Intel AMT functionality.Access to ports 16992/16993 are the only requirement to perform a successful attack," Embedi states in its whitepaper.Once a system is compromised, a remote attacker can take control of the keyboard, mouse, and monitor to perform physical actions that users would normally do when sitting in front of a system—load and execute programs, read and write files, and so forth.The attacker would also be able to remotely change the boot device (to a virtual image, for example), power on and off a system, access the BIOS, and more.Security firm Tenable followed up on Embedi's disclosure with an investigation of its own to see how serious the vulnerability really is.

using a specially crafted requests, Tenable was able to completely bypass the authentication scheme of an AMT-enabled system and gain access without providing a proper password.Updated firmware can't come fast enough.bitcoin core forkTo that end, Fujitsu, HP, and Lenovo have each promised updates in the near future.bitcoin tax implicationsblog comments powered byhow to mine litecoin 2014Ethereum Sign up or log in to customize your list.bitcoin guadagni_ Here's how it works: Anybody can ask a question Anybody can answer The best answers are voted up and rise to the top up vote 7 down vote favorite 1 What is ether?bitcoin sukses

How does it differ from past tokens such as bitcoin and litecoin?What are all the usages of ether?ether up vote down vote Ether serves two main purposes for ethereum: Just like Bitcoin and Litecoin on their respective blockchain, ether is a fungible asset/currency on the ethereum blockchain that creates the necessary incentive for miners to maintain the network.ethereum tax ukUnlike Bitcoin and Litecoin, ether is also used to pay for the computations that you ask the network to perform.Since one can submit arbitrary code to be executed on the ethereum blockchain, this mechanism ensures that your code won't run forever and thus clog up the entire network.See the halting problem.You also need to pay ether for submitting new contracts to the blockchain, so that we won't have a million contracts using up excessive storage.When ether is used in this way, to pay for computation and storage, it is called gas.

More about gas here: https://ethereum.gitbooks.io/frontier-guide/content/costs.html up vote 6 down vote The primary use of Ether is : To pay for Gas that are required of all transactions (contracts and non contract txs).Ether is also used as a reward for miners who help secure the network through POW (though this will all change in the future when POS is implemented) And because Ether has utility, this gives it a value.Which means that it can be used for exchange of services, goods, virtual tokens.This does make it similar like a currency, although it was not designed as the primary use.up vote 1 down vote May 2017 UPDATE The role of Ether is quickly evolving beyond the original purpose for the Ethereum community, and so I want to add two emerging new uses: (1) Start-up Financing.Bitcoins and Ethers are now being used in crowsdsales of blockchain-based products and cryptocurrency ventures, as part of ICOs (Initial Coin Offerings).

Here is a list of ICOs, a number of which (like Bancor) require Ethers./icos/ (2) As a reserve currency for smart tokens.The Bancor Network has published a white paper explaining its plan to start using the Ether as a reserve currency for the Bancor (The Ether will back the Bancor in a specific given ratio, the CRR, i.e.the credit reserve ratio, still to be announced).This will help to keep the Bancor liquid, and ensure that any smart token issued on the Bancor Network can be immediately exchanged for any other.Read these to better understand these new roles for the Ether.https://bancor.network/static/Bancor_Protocol_FAQ.pdf https://bancor.network/static/Bancor_Protocol_Whitepaper_en.pdf https://blog.bancor.network/coins-are-networks-and-crowdsales-are-their-killer-app-a6ebc16bef31 up vote 1 down vote As far as I know , Ether is a element (a fuel) for operating the distributed application platform ethereum.It is a form of payment made by the clients of the platform to the machines executing the requested operation .
