SECURITATE  ●  Inventar al slăbiciunilor internetului
Hackerii s-au strîns în conferinţă pentru a discuta despre metode de atac pe care le au la îndemînă. Sistemele wireless, dar şi trecerea internetului la protocolul IPv6 le oferă o perspectivă încurajatoare.
E din ce în ce mai greu să Å£ii pasul cu noile ameninţări informatice care te aÅŸteaptă din momentul în care începi să navighezi pe internet. SoluÅ£ia absolut necesară, aceea a instalării unui software de securitate, nu îţi oferă nici pe departe garanÅ£ia că este ÅŸi suficientă. Vulnerabilităţile care dau hackerilor ÅŸansa unui atac de succes sînt tot mai surprinzătoare, cel mai recent exemplu fiind cel al “scăpărilor” din definirea protocoalelor de funcÅ£ionare a internetului. A fost nevoie de ÅŸase luni pentru ca o echipă de specialiÅŸti ai celor mai mari nume din industria de soft să găsească o rezolvare acelei probleme.

BREÅžE. Una dintre vulnerabilităţile care pot fi exploatate de hackeri este dată de tranziÅ£ia internetului de la protocolul de comunicaÅ£ie IPv4 la varianta mai nouă, IPv6. Aceste protocoale definesc practic felul în care se desfăşoară traficul pe net. Joe Klein, specialist pe probleme de securitate, atrage atenÅ£ia asupra faptului că multe sisteme informatice au integrate deja ambele protocoale, fără ca utilizatorii să ÅŸtie acest lucru. Problema vine din faptul că multe dintre soluÅ£iile de securitate nu sînt pregătite să monitorizeze traficul prin IPv6, lăsînd astfel cale liberă atacurilor care exploatează această “uşă deschisă” către ÅŸi de la calculatorul cu pricina. Securitatea informatică a fost discutată pe toate feÅ£ele week-end-ul trecut, în cadrul conferinÅ£ei “Hackerilor de pe Planeta Pămînt” (HOPE), din New York.
Vulnerabilitatea sistemelor Wi-FI, Bluetooth şi RFID (etichete cu radio-frecvenţă) a fost un alt subiect important de discuţie. Slaba criptare a transmisiei wireless de date, mai ales în cazul hotspot-urilor publice, breşelor de securitate ale tehnologiei Bluetooth şi uşurinţei cu care pot fi citite etichetele care folosesc RFID, folosite deja în paşapoartelor cetăţenilor americani, sînt doar cîteva puncte din inventarul slăbiciunilor pe care hackerii le pot exploata.

Până la sfârşitul lunii, şoferii pot circula fără să fie amendaţi dacă nu au cumpărat rovinietă.

Ministerul Transporturilor (MT) va suspenda, în perioada 21-31 iulie, aplicarea amenzilor în cazul şoferilor depistaţi fără roviniete, ca urmare a introducerii unor noi modele, operaţiune din cauza căreia pot exista puncte de distribuţie fără stocuri de roviniete.
„Având în vedere introducerea noilor modele de roviniete, precum şi faptul că rovinietele-ecuson şi rovinietele matcă-cupon nu pot fi eliberate simultan de punctele de lucru ale aceluiaşi distribuitor, din cauza aplicaţiilor informatice diferite utilizate la eliberarea acestora, pot exista puncte de distribuţie care nu vor dispune de stocuri de roviniete.

Din cauza acestor modificări (…), MT a luat decizia să suspende aplicarea amenzilor contravenÅ£ionale utilizatorilor depistaÅ£i fără rovinietă valabilă în perioada 21.07.2008-31.07.2008“, se arată într-un comunicat al instituÅ£iei.

Publicarea unor fotografii cu oameni care făceau plajă liniştiţi, la numai câţiva metri de cadavrele a două fetiţe de etnie romă care se înecaseră lângă Napoli, a stârnit revolta presei italiene şi internaţionale.
Povestea celor două copile a fost preluată rapid de publicaţii din întreaga lume. Agenţia de presă italiană ANSA a relatat că incidentul a avut loc sâmbătă, pe plaja din Torregaveta, la vest de Napoli (sudul Italiei), notează CNN.
Cele două fetiţie, Cristina Ibramovici şi Viola Ibramovici, de 12, respectiv 11 ani, care erau rude, dar nu surori, veniseră pe plajă pentru a cerşi şi a vinde podoabe ieftine împreună cu alte două fete de etnie romă, relevă „The Daily Mail“.
La un moment dat, copilele au intrat în apă să înoate, dar au fost surprinse de valuri mari şi curenţi puternici. Salvamarii au reuşit să le salveze însă doar pe două dintre ele. Corpurile celor două fetiţe înecate au fost scoase din apă şi duse pe plajă, după care au fost acoperite cu prosoape în aşteptarea autorităţilor care trebuiau să vină să le ridice.
Ziarele italiene au notat însă că incidentul a constituit o neplăcere minoră pentru cei care veniseră la plajă, mulţi stând la soare în apropiere de locul în care se vedeau ieşind de sub prosoape picioarele celor două fete.

Indiferenţă la malul mării
„Cadavrele au fost lăsate pe plajă pentru o oră înainte să fie ridicate, acoperite cu prosoape, în timp ce oamenii s-au întors să facă plajă sau să joace fotbal“, a povestit pentru televiziunea italiană un martor ocular, citat de „The Daily Telegraph“, „Era suprarealist. Aveai imaginea unei plaje italiene tipice, cu familii care se bucură de soare, şi numai la câţiva metri distanţă erau cadavrele a doi copii. Oamenii au fost total indiferenţi la ce s-a întâmplat“, a adăugat martorul ocular.

BELGRADE, Serbia (CNN) — Former Bosnian leader Radovan Karadzic will fight extradition from Serbia on war crime charges, his lawyer said Tuesday.

Lawyer Sveta Vujacic also disputed Serbian accounts of Karadzic’s arrest alleging the man known as the ‘Butcher of Bosnia’ was seized Friday and held in secret for three days.

Karadzic, 63, is accused of ordering the deadly siege of Sarajevo and some of the worst atrocities in Europe since World War II including the 1995 massacre of 8,000 Muslims in Srebrenica

Vujacic said Serbian authorities were not telling the truth about Karadzic’s arrest.

“Nobody seems to know who arrested him and where he has been since last Friday at 21:30 hours, when he was arrested,” he said.

“He just said that these people showed him a police badge and then he was taken to some place and kept in the room. He was blindfolded … he was kept in some room … and that is absolutely against the law what they did.”

Vujacic said he will launch criminal proceedings in addition to an appeal against Karadzic’s transfer to the International Criminal Tribunal for the Former Yugoslavia (ICTY) at The Hague.

STOCKHOLM, Sweden (AP) — Asafa Powell took on the world’s fastest man with every intention of beating him to the finish line.

Usain Bolt just couldn’t catch up in time.

Powell capitalized on Bolt’s weak start and edged the world-record holder by one-hundredth of a second, leading from start to finish in the 100 meters at the DN Galan meet on Tuesday.

Powell, the former world-record holder, won their highly anticipated rematch in 9.88 seconds. Bolt, who was slow out of the blocks, nearly caught his fellow Jamaican at the finish line. Third went to Norwegian Jaysuma Saidy Ndure in 10.06.

“I was really happy with the race,” Powell said. “My goal was to win. My start was quick and fast. And the speed stayed with me through the finish.

“I’m really looking forward to the Olympics.”

The win was a measure of revenge for Powell, after losing to his close friend Bolt at Jamaica’s Olympic Trials last month.

Bolt set the world record of 9.72 in New York on May 31, breaking Powell’s mark of 9.74.

It was Powell’s third straight win at Olympic Stadium. Last year, he won in 10.04. In 2006, he set the stadium record of 9.86.

“I needed today’s win for my confidence,” Powell said. “That is most important in order to get really good times.”

Bolt was somber.

“I’m disappointed,” he said. “My start was not good enough. That was the key tonight. I was also disturbed by the false start. I could not focus at 100 percent.”

NEW YORK (AP) – The old song had it right: Breaking up is hard to do. But a free new phone service called Slydial might make it easier to get through that and other awkward moments — without actually having to talk to anyone.

Slydial lets you connect directly with another person’s cell phone voice mail, bypassing the traditional ringing process that often results, sometimes disastrously, with someone picking up on the other end.

Users call (267) SLY-DIAL from either a cell phone or a landline and are prompted to enter another person’s cell phone number.

After playing a short advertisement — unless users pay a subscription fee or 15 cents per call to skip ads — Slydial puts callers directly into their target’s voice mail.

Recipients should then get a voice mail notification, and sometimes they will see a caller’s number show up as a missed call, too.

Gavin Macomber, co-founder of MobileSphere Ltd., the Boston-based communications company behind Slydial, thinks it can be useful not only in the dating scene but in the hectic business world.

“Everybody has gone through the scenario where they’ve called somebody and just hoped they got voice mail so they didn’t have to have a conversation,” he said.

GUANTANAMO BAY, Cuba (CNN) – Osama bin Laden’s former driver knew the target of one of the hijacked planes on September 11, 2001, prosecutors said as the military commission trial of Salim Hamdan began Tuesday.

Hamdan told U.S. interrogators the fourth plane was aimed at “the dome,” apparently a reference to the U.S. Capitol, the prosecutors said. The plane crashed in a field in Pennsylvania after the passengers fought the hijackers.

But the defense said Hamdan was a low-level driver who knew little about the workings of bin Laden’s al Qaeda network. They said he worked for wages, not to wage attacks against America.

Captured at a roadblock in Afghanistan in November 2001, Hamdan pleaded not guilty at the start of the trial, which will be closely watched as the first full test of the Pentagon’s system for prosecuting alleged terrorists.

He faces a maximum life sentence if convicted of conspiracy and aiding terrorism.

The first prosecution witness, a U.S. soldier who was present when Hamdan was captured, originally said Hamdan was driving a car that had SA-7 surface-to-air missiles intended for al Qaeda. But on cross-examination, the soldier, identified only as Maj. Smith, said he could not be sure Hamdan was the driver of one of the three vehicles carrying the missiles.

LONDON - The oldest surviving copy of the New Testament, a 4th century version that had its Gospels and epistles spread across the world, is being made whole again — online.

The British Library says the full text of the Codex Sinaiticus will be available to Web users by next July, digitally reconnecting parts that are held in Britain, Russia, Germany and a monastery in Egypt’s Sinai Desert.

A preview of the Codex, which also has some parts of the Old Testament, will hit the Web on Thursday — the Book of Psalms and the Gospel of Mark.

“Only a few people have ever had the opportunity to see more than a couple of pages of the (Codex),” said Scot McKendrick, the British Library’s head of Western manuscripts. The Web site will give everyone access to a “unique treasure,” he said.

Discovered at the Monastery of Saint Catherine at Mount Sinai by German Bible scholar Constantine Tischendorf in the mid-19th century, much of the Codex eventually wound up in Russia — just how exactly the British Library won’t say, citing lingering sensitivity over the circumstances surrounding its removal from the monastery.

SAN FRANCISCO - Yahoo Inc.’s profit slipped again in the second quarter, a recurring theme that has frustrated shareholders and raised doubts about the Internet company’s future.

While the results released Tuesday missed analyst expectations, the performance wasn’t as bad as many investors feared after Internet search and advertising leader Google Inc. disappointed Wall Street with its second-quarter earnings last week.

What’s more, Yahoo management maintained its revenue outlook for the remainder of 2008. The confident stance eased concerns about Yahoo’s financial erosion worsening amid the dreary economy in the United States and parts of Europe.

Yahoo shares rebounded 58 cents in extended trading after falling 27 cents to finish Tuesday’s regular session at $21.40.

“They did better than the worst expectations,” said Canaccord Adams analyst Colin Gillis. “It was a ‘rice-cracker’ quarter. It didn’t taste great, but it wasn’t totally horrible either.”

The Sunnyvale, Calif.-based company earned $131 million, or 9 cents per share, from April through June. That was down 18 percent from $161 million, or 11 cents per share, at the same time last year.
