A pseudonym once recollected so for the hacker of Hacker:
In June 2013, he discovers flaw hind in exchange of ten bit money, fine long hair raised all bit money without let or hindrance. After raising money, he sold these bit currency on Localbitcoins.com, that day of ready money that he earned 8000 dollars, be equivalent to the salary of 4 months, the feeling resembles be in heaven.
The bit currency value 2013, in experienced a rise and fall to lag behind, highest Ceng Sheng comes more than 1242 dollars, this one price manages to tall Yu Yiang very the price of gold.
Of bit money " digital gold " the name must come from this.
After this, the bit money fictitious money that is based on area piece catenary to be born, become a hacker to like the end of attack most.
Recently, tecent safety knows to achieve eaves to release jointly " 2018 safety of area piece catenary reports first half of the year " show, domain of area piece catenary exceeded 2.7 billion dollar because of safe problem loss first half of the year 2018, among them because the number adds close money,1.1 billion dollar is by pilfer.
"The global hacker that we trace, have 30 much person or organization are atttacking area piece catenary, basic the hacker of 90% is staring at area piece catenary, area piece catenary regards as opportunity extraction a money is same. " Beijing knows author of limited company of the IT that start house holds CEO Zhao Wei concurrently to be opposite Truth of area piece catenary says.
1/4 intelligence agreement puts hole, loss of half an year the data that 2.7 billion dollar provides according to Tecent safety, atttack incident with the hacker that adds secret number money to concern, arrive from 2013 2018 (first half of the year) increased directly about fivefold amount, annual predicted to increase 2018 about decuple.
Area piece catenary is safe in last few years incident statistic
Report of safe company Hosho shows, the Bug of agreement of the intelligence on area piece catenary exists generally. The intelligent agreement project that passes Hosho audit prepares market fund total to be as high as 1 billion dollar, these have 25% to be discovered to be put in serious flaw in the project, about 60 ％ are put in a safe problem at least.
It is before this, know to achieved eaves to also issue a very similar report.
Be in those who know to achieve eaves to release " know to achieve CheckList of audit of contract of eaves aether lane " in, announced know to start house 404 areas piece catenary safety studies the group is made public in the light of entire network in all the result that 39548 agreement code scans. The result shows, end on August 10, 2018, discovery in all 24791 (occupy involve agreement of aether lane intelligence to design blemish issue than 62%) agreement (include " conditional competition issue " , " circular DoS problem " wait for a problem) .
Among them, have " issue of Approve condition competition " agreement has 22981, and 15325 agreement still are in even trade condition, the result of flaw of Approve condition competition may cause the problem that loses money; Have " circular DoS problem " agreement has 1810, among them 1740 agreement still are in trade condition, doS of the loop in aether lane has been used up possibly because of Gas bring about greatly trade failure, agreement cannot be carried out.
The agreement of aether lane intelligence of more than 60% appears design flaw problem, also mean the digital money system that is based on these intelligent agreement to also be put in safe hidden trouble.
Hacker, be gaze at this one safe problem that adds secret number money.
Science and technology of trend of provider of network safety solution expresses in a new research, the attention of network criminal from blackmail software attack quickly to turn for slower, more resource of covert filch computer computation adds close money with mining. This research shows as a result, with annual photograph was compared 2017, detected first half of the year 2018 add close money to dug mine to increase 96% , the virus digging mine that detects and photograph comparing increased first half of the year 2017 956% .
" 2018 safety of area piece catenary reports first half of the year " medium data shows, area piece catenary because the pecuniary loss that 3 respects cause the safety of oneself mechanism, zoology safety and safety of the person that use, it is respectively 1.25 billion, 1.42 billion with 56 million dollar, add up to be as high as 2.7 billion dollar.
The actor that Nasidake lands before this is equivalent to this believes the total market prise of the company.
The loss is maximum is digital currency trades platform, it is 1.34 billion U.S. dollor in all. It is intelligent agreement next, basically be to be centered on aether lane, for instance the flaw because of code or of illicit key divulged the capital loss that waits for a reason to bring about to achieve 1.24 billion U.S. dollor. It is the attack that individual user suffers again, computer is for instance medium key of virus, illicit be waited for by filch, the episode of a few virus that includes a miner is waited a moment.
"The hacker is right the attack of area piece catenary still can last all the time, meet even increasing. " a safe personage tells area piece catenary Truth.
The whole world exceeds 300 thousand person or the organization is atttacking area piece catenary
"Because area piece catenary and digital money domain do not have a person to care about safety before, after the value that area piece catenary forms rises suddenly, to the hacker here resembles a bank, they take money casually. They take money casually..
From 2011, zhao Wei begins to pay close attention to bit money, knew to achieve eaves to begin to be the platform such as the bourse that increases field of secret number money, purse to provide the safe defence of digital asset 2013.
"Hacker " (the hacker's original idea is limit of the breakthrough on the technology) he of one's previous experience, most the method that knows a hacker.
"Now hacker area piece catenary regards as shooting range. The global hacker that we trace, have 30 much person or organization are atttacking area piece catenary, so basic the safe problem that the hacker of 90% is staring at area piece catenary. And once after breach, area piece catenary is faceless, asset was lost do not have a law to search, so hackers area piece catenary regards as opportunity extraction a money is same. " Zhao Wei says.
Basis this year the area May 30 piece chain industry safety analyses a report, the whole world produces the trend of incident of safety of area piece catenary to present ascendant state of year after year. Appeared 2011 incident of safety of money of first time bit, lose 1.02 million U.S. dollor at that time; 2014 global area piece the capital loss of catenary is 460 million U.S. dollor probably; And arrived this year first half of the year, this number achieves 1.9 billion U.S. dollor.
One of, problem of mechanism of oneself of area piece catenary. With what aether lane is a delegate agreement of intelligence of area piece catenary designs the flaw issue of existence, brought pecuniary loss is very severe. In June 2016, aether lane most The DAO of masses preparing project is atttacked, the hacker obtains money of more than 3.5 million aether, bring about aether lane bifurcate finally to be ETH and ETC. In the meantime, real division piece catenary network is opened freely, theoretic natural resources of computer of the great majority in be like a hacker to control node, can change mutual Zhang again this, final implementation 51% " double flower is atttacked " .
Secondly, problem of safety of zoology of area piece catenary. The node of rights and interests below mechanism of the mine field that PoW mechanism includes to fall in zoology of area piece catenary and mine pool, PoS, add exchange of secret number money, soft hard purse, data to dog browser, DApp application, and the area that faces prospective DApp application piece catenary gateway system. Among them, the safe event that produces around bourse is most remarkable, bourse by pilfer Yuan Chao other event type. In addition, bourse is fished, inside all sorts of have things stolen of ghost theft, purse, information data are divulged and distort, the problem such as have things stolen of bourse Zhang date, be worth to pay close attention to as much.
Thirdly, the safe problem that him person that use creates. Because the number is fictitious money purse these trading of the tool make appliance has higher threshold, the person that the requirement is used is right the computer, add safety of close principle, network to all have taller acknowledge. However, a lot of numbers are fictitious currency trades participator does not have these capacity, appear extremely easily safe problem. Because the operation is undeserved,cause acquaintance to commit the crime even, digital asset by beside person purloin.
Look in Zhao Wei, the attack ability of Chinese hacker and safe research capability are very strong, safe firm of the United States' toppest scientist is basic it is a Chinese, "Just our safe market closes compasses sex, it is governmental demand what is, among them increase chain is daedal. Among them increase chain is daedal..
This also is meant, the network of Chinese churchyard is safe, opposite relatively normative.
Destroy consensus, safe problem is aided push digital money Xiong Fu from this year first since, bit currency value falls all the way from the high point of 20 thousand dollar split 6000 dollars, total market prise of global number money drops to 300 billion dollar from the 6500 much dollars of the beginning of the year around. Money circle is experiencing endless Xiong Fu.
Look in Zhao Wei, this Xiong Fu follows safety of area piece catenary not to have nothing to do is.
"Hacker pilfer money, atttack system of area piece catenary, the greatest harm is the consensus that destroyed area piece catenary, broke faith. " Zhao Wei says.
The consensus mechanism of area piece catenary is the important regulation that its run
Look in him, the target at the beginning of bit money is born is digital gold. "Gold is not for small trade and pay, however value is saved, reach consensus quickly with mathematical algorithm. Its target is safe, so the bit money of generation, before hold measures a rank to lean is safe personnel completely. Before hold measures a rank to lean is safe personnel completely..
When hacker pass through the territory of a country, think people the safest " digital gold " after purloin, everybody discovers it is insecure, "Do not have consensus, be bungled easily dish, the hacker is here the face was to reap everybody, and the kill the goose that lays the golden eggs that is an extreme. And the kill the goose that lays the golden eggs that is an extreme..
Can say, the division that frequency gives piece catenary safety problem, help the integral ursine city that pushed digital currency.
Link bit currency actually, ever also had encountered " disaster " . On August 15, 2010, a hacker ever was in bit money height 74, the area of 638 piece go up, through a of bit money former unripe Bug created money of 184.4 billion bit overnight.
Because the price of money of the bit when those is not seductive,be probably, this hacker is being finished this one " feat " hind the attack action that did not have sequel, avoid at allowing bit money " inflation " hind break down.
Although the hacker has opened fun hind, left approvingly, but this one Bug was psyched out however bit money code safeguards a group at that time. The chief developer Wladimir Van Der Laan of bit money community is when memory speak bluntly: "This is the problem with the most serious throughout history " .
2014, ever happened one case famous " door head channel " incident, once was the bit money with the biggest whole world trades because platform Mt.Gox is gone bankrupt finally by hacker pilfer money, money of about 750 thousand bit (value 375 million dollar) Fu Zhidong flows, cause bit currency value to drop greatly.
The closest be in in March 2018, money installs bourse to be atttacked by the hacker, the hacker goes through making empty instrument field coat shows benefit. Suffer this incident to affect, bit money steeps fall 10% .
Look nowadays, almost every time of the hacker hit out, metropolis more or less those who cause bit money price drop.
"Safety of area piece catenary is the one part in Internet safety only, but because area piece chain is the biggest the characteristic is to be based on consensus, and consensus is law, agreement, fortune in the expression of real world. Once produce safe event, suffer lose opposite more serious. " Zhao Wei says.
