    @hellscream uite si optimizarea:

    optimizare.png

    Ai doua puncte: A1 si B1 de coordonate cunoscute. Punctele A, B si C le "ceri" tu coordonatele. si rezulta un triunghi ABC. Trasezi 2 cercuri: Unul cu centrul in A1 si cu raza A1-A si celalalt centru in B1 si raza B1-B. Ele se intersecteaza in doua puncte.(eu nu le-am mai denumit dar poti sa le zici C1 si C2).

    Apoi compari rapoartele (A1-A)/(C1-C) cu (A1-A)/(C2-C) si alegi punctul pentru care raportul da cel mai mic rezultat.

    E o metoda asemenatoare cu metoda triangulatiei.

    Poti sa o aplici si in script :))

    Synthesis = esti prost. Asa de usor a fost sa fac o afirmatie.. insa nu stiu daca este fondata sau nu. Banuiesc ca tot atat de usor ti`a fost si tie.. nu stiu daca este bine sa facem afirmatii gratuite, pt a parea "shmecheri" , "bazati" , hackeri etc. Nu am observat sincer.. ca este un topic de.. demult, sa zic asa.

    In fine, spor la treaba la toata lumea

    Cand o sa treci de pubertate, o sa ai dreptul sa ma faci prost. Pana atunci, stai in banca ta. Daca zici ca nu ai observat ca a fost un topic de demult, ce cautai in el? Ai auzit si tu undeva de Vladuz si gata, ai venit sa ne luminezi.

    Bai baieti.. il stie cineva de aici personal pe vladuz? Pareri.. da, de fapt un forum pe asta se bazeaza, insa ca idee, eram arestat si eu, cand l`au luat pe el. Si.. psss, baietiii, omu era cautat, si a facut o greseala, minora, de altfel majora, de a folosi un BNC cumparat de la un om care il considera prieten. Ca om, este un tip fff OK, iar ca hack.. trageti voi concuziile.

    Te-ai trezit sa faci si tu un post ca sa-ti mai cresti numarul de inutilitati aduse forumului. Nu ne intereseaza faptul ca il cunosti personal pe Vladuz si nici ca a fost prins folosind un BNC cumparat. Ne-a oferit doar o lectie Vlad si anume aceea ca sa nu folosesti hacking-ul in scopuri distructive.

  15. Anonymous a atacat site-uri guvernamentale din Turcia

    in Stiri securitate

    Atacurile cibernetice asupra unor institutii guvernamentale continua sa se produca pe plan international. Ultima "isprava" apartine celor de la Anonymous, care au anuntat lansarea de atacuri de tip DdoS (distributed denial of service) asupra catorva website-uri guvernamentale turcesti.

    Motivul il reprezinta protestul organizatiei impotriva deciziei guvernului de a introduce cenzura pe internet in Turcia. Aceasta miscare vine la numai cateva zile inainte ca in Turcia sa fie organizate alegeri parlamentare.

    Joi seara, site-ul apartinand Telekomünikasyon ?leti?im Ba?kanl?? (tib.gov.tr), institutia care reglementeaza regulile traficului pe internet si care vrea sa introduca planul de cenzura, nu mai era accesibil.

    Prin lansarea acestor atacuri, este posibil ca grupul Anonymous sa fi intrat in conflict cu alte organziatii de hackeri din Turcia, care ar fi amenintat ca vor sparge site-urile Anonymous, se arata intr-un raport.

    Nici site-ul de stiri al Anonymous, anonnews.org, nu mai era accesibil joi seara. Grupul nu a facut pana acum niciun comentariu despre acest incident. Departamentul de Informatii al Turciei, de asemenea, nu a avut nicio reactie oficiala.

    Cetatenii turci protesteaza fata de noile reguli de navigare pe internet care vor intra in vigoare pe data de 22 august si care vor obliga userii sa aleaga unul din cele patru filtre inainte de a se conecta la retea. Intr-o petitie publicata pe Avaaz.org, un forum online, protestatarii au cerut autoritatilor de la Ankara sa retraga orice filtru sau regula care impiedica utilizatorii sa navigheze liber pe internet.

  16. Spain nabs 3 suspected of global cyber attacks

    in Stiri securitate

    Posted

    MADRID – Spanish police have arrested three suspected computer hackers who allegedly belonged to a loose-knit international activist group that attacked corporate and government websites around the world, authorities said Friday.

    National Police identified the three as leaders of the Spanish section of a group that calls itself "Anonymous." All three are Spaniards aged 30 to 32, said Manuel Vazquez, chief of the police's high-tech crime unit.

    A computer server in one of their homes was used to take part in cyber attacks on targets including two major Spanish banks, the Italian energy company Enel and the governments of Egypt, Algeria, Libya, Iran, Chile, Colombia and New Zealand, Vazquez said.

    His comments backtracked somewhat from an earlier police statement that said this server was used to actually execute the attacks. The three detainees have been released without bail but face a charge that is new in the Spanish penal code — disrupting a computer system, Vazquez said. He gave no details on what effect these attacks had.

    In Spain, acting on their own, the three detainees staged cyber attacks on the website of Spain's central electoral commission a few days before local and regional elections on May 22, that of the regional police force in the northeast Catalonia region and a major Spanish labor union.

    The night before the election, the three men tried to shut down the web pages of Spain's two main political parties and that of the Spanish parliament but were thwarted by police, Vazquez said.

    "Anonymous is a network with a common idea, but it has loads of cells around the world. Using chats they agree to stage denial-of-service attacks on any page of any company or organization anywhere in the world," Vazquez said, referring to a cyber-bombardment-like technique used to shut down an Internet page.

    Vazquez said police were still analyzing computer files and other material but have no record of the three Spaniards having obtained sensitive data.

    Vazquez said members of Anonymous use a lot methods for hiding their identity.

    The statement said the only other countries to act against "Anonymous" so far are the United States and Britain. It attributed this what it called complex security measures that members use to protect their identity.

    The suspects in Spain were arrested in Barcelona, the Valencia region and the southern city of Almeria.

    Since October 2010, Spanish police specializing in cyber crime have analyzed more than two million lines of online chat and Internet pages until they finally zeroed in on the three suspects. Their names were not given.

    In January, British police arrested five young males on suspicion of involvement in cyber attacks by Anonymous, which has backed WikiLeaks.

    "Anonymous" has claimed responsibility for attacking the websites of companies such as Visa, Mastercard and Paypal, all of whom severed their links with WikiLeaks after it began publishing its massive trove of secret U.S. diplomatic memos.

    "Anonymous" accused the companies of trying to stifle WikiLeaks and rallied an army of online supporters to flood their servers with traffic, periodically blocking access to their sites for hours at a time.

    And in February, an Internet forum run by "Anonymous" directed participants to attack the websites of the Egyptian Ministry of Information and the ruling National Democratic Party.

    In a Twitter post, the group claimed credit for taking down the ministry's website and said the group was motivated by a desire to support Egyptian pro-democracy protesters.

  17. Vietnam websites hacked amid China row

    in Stiri securitate

    HANOI (AFP) – More than 200 Vietnamese websites have been attacked and some defaced with Chinese flags, an Internet security firm said Friday as a maritime dispute raises tensions between the countries.

    The ministries of agriculture and foreign affairs are among those targeted since the beginning of June, said Nguyen Minh Duc, director of the state-linked Bach Khoa Internetwork Security Centre (BKIS).

    Hackers sometimes left "information in Chinese and Chinese flags," he told AFP.

    "We don't yet know if it concerns Chinese hackers," Duc said.

    Foreign ministry spokeswoman Nguyen Phuong Nga told reporters on Thursday that "a number" of Vietnamese websites had been hacked, including one from the ministry's translation centre.

    Tensions between China and Vietnam are at their highest level in years after Hanoi accused three Chinese marine surveillance vessels of cutting the exploration cables of an oil survey ship in May inside its 200 nautical mile exclusive economic zone.

    On Thursday Vietnam alleged a similar incident, saying a Chinese fishing boat rammed the cables of another oil survey ship in its waters.

    Beijing countered by warning Vietnam to halt all activities that it says violate its sovereignty in disputed South China Sea waters.

    The two countries have long-standing disputes over the potentially oil-rich Paracel and Spratly archipelagos and surrounding waters.

    Hundreds of people held a peaceful anti-China protest outside Beijing's embassy in Hanoi on Sunday, the largest action of its kind since 2007.

    Protests are rare in authoritarian Vietnam but web users have been debating whether or not to hold another rally.

  18. Expert warns NATO of cyber arms race

    in Stiri securitate

    TALLINN (AFP) – The world is entering an era of a cyber arms race where ever-more sophisticated versions of malware are the weapons of choice of actors often impossible to trace, a top IT expert told NATO Friday.

    "We are entering the era of a cyber arms race, but the problem in this arms race is we don't know what kind of new arms the others have, so we don't have a quick, effective means to counter them," Mikko Hypponen said at a meeting on global cyber conflict organised by the Tallinn-based NATO Cyber Centre.

    "And we often don't know also who is in charge, who has these weapons," said the Finn, who works for a top global IT security firm.

    Hypponen is known for having been involved in weeding out the feared Storm and Stuxnet computer worms and has assisted authorities in the United States, Europe and Asia in cracking global cyber crime.

    He singled out defence contractors, government and non-governmental organisations as the "three main large target groups of hackers."

    "We are following daily how hackers break into computers and take them over without users having the slightest idea what is going on," Hypponen said.

    "The damage arrives usually with the attachment from a sender you know or trust fully, having been linked even to mail looking like arriving from the US Department of Defence, World Bank, United Nations etc., but having in fact nothing to do with them," he added.

    He said failures in a widely-used documents system were largely to blame.

    "Current technologies are simply failing," charged Chris Brown, an expert from US network security company NetWitness.

    "People underestimate the complexity and capability of cyber threat and are not taking proactive steps," he warned.

    A NATO official announced this week at the Tallinn conference that the alliance plans to beef up its cyber defence capabilities with the creation of a special task force to detect and respond to Internet attacks.

    The Symantec cyber security firm recently reported that web-based attacks in 2010 were up 93 percent from 2009.

    The June 7-10 NATO cyber security conference attended by 300 top IT experts from across the globe focuses on the legal and political aspects of national and global Internet security.

  22. Facebook incalca din nou confidentialitatea utilizatorilor

    in Stiri securitate

    Posted

    Facebook a extins in tacere aria de acoperire a tehnologiei de recunostere faciala, reinnoind astfel temerile referitoare la politicile de confidentialitate ale celei mai mari retele sociale din lume.

    Feature-ul, pe care Facebook l-a activat automat pentru toti userii Facebook, a fost extins de la Statele Unite la “majoritatea tarilor”, potrivit informatiei postate pe blogul retelei de socializare.

    Functionalitatea “Tag Suggestions” foloseste tehnologia de recunoastere faciala pentru a accelera procesul de “etichetare” a prietenilor si a cunostintelor care apar in fotografiile postate pe Facebook.

    Implementarea acestei tehnologii a starnit un val de ingrijorari in randul specialistilor din industrie. Compania de securitate Sophos atragea atentia pe blog ca in ultimele zile utilizatorii Facebook au raportat activarea automata a optiunii de recunoastere faciala, fara a primi in prealabil o notificare de la Facebook.

    Facebook, care si-a anuntat in decembrie planurile de a introduce acest serviciu in Statele Unite, a recunoscut ca feature-ul este acum disponibil in mai multe regiuni.

    Serviciile online ale Google si Apple, Picasa, si respective iPhoto folosesc de asemenea tehnologia recunoasterii faciale, insa folosirea unei astfel de functionalitati pe o retea sociala cu peste 500 de milioane de utilizatori ridica numeroase semne de intrebare cu privire la confidentialitate.

    In plus, software-ul iPhone de exemplu, le ofera utilizatorilor control asupra tehnologiei de recunoastere facial, oferindu-le optiunea de a folosi sau nu tehnologia recunoasterii faciale pe colectiile de fotografii personale.

    Functionalitatea oferita de Facebook functioneaza la polul opus, operand independent si analizand fetele din pozele uploadate recent.

    Specialistii in securitate sustin ca un astfel de sistem ar putea contribui la asocierea fotografiilor cu adresele de email.

    Voi ce parere aveti, noua tehnologie de recunoastere faciala constituie o amenintare la confidentialitatea informatiilor personale de pe Facebook?

  24. NATO tackles cyber security at Tallinn meet

    in Stiri securitate

    Posted

    TALLINN (AFP) – Three hundred global cyber experts gathered in Tallinn Tuesday for a NATO Cyber Conflict conference focused on the legal and political aspects of national and global Internet security amid a rise in attacks.

    "The special focus at the conference this year is on generating cyber forces (...) the technologies, people and organisations that nations require to mitigate cyber threats that have been increasing with rapid speed," Colonel Ilmar Tamm, head of NATO's Tallinn-based Cyber Defence Centre told AFP as the forum got underway Tuesday.

    According to Tamm, the Symantec cyber security firm recently reported that "web-based attacks in 2010 were up 93 percent from 2009."

    "This calls for frameworks in both legal and strategic aspects which would guide the decision makers on how to act on these cases," Tamm said.

    The Tallinn conference will coincide with a NATO defence ministers' meeting in Brussels where a new cyber defence policy for NATO will be adopted.

    Meanwhile, at the third annual Tallinn meeting, experts from 37 countries are to share cutting-edge cyber security research, Tamm explained.

    Among others, Ralph Langner, the German computer scientist who conducted much of the ground-breaking research on the Stuxnet worm, will present an analysis of what has been called the world's first cyber weapon.

    Keir Giles from the UK Conflict Studies Research Centre is to analyze global cyber attacks from Russia and whether they can be seen as acting under a so-called Russian Cyber Command.

    Talks will also focus on the recent US government decision to treat cyber attacks as military attacks and make relevant legislative changes.

    "The support the US initiative has got in many other states, including Estonia and the UK, indicates nations? increasing willingness to discuss military responses to cyber attacks," Tamm told AFP.

    "With cyber incidents becoming more and more intrusive, it is a logical step for militaries to develop capabilities to counter cyber attacks and be prepared to engage in proportional response to cyber attacks," he added.

    Though in practice, "it will be challenging to tailor a cyber response that would respect the rules of combat related to civilian objects and collateral damage," he added.
