Chipmaker Nvidia announced that a new supercomputer built in China, powered by over 7,000 of its graphics processor units (GPUs), is now the world's fastest. This supercomputer, constructed by the National University of Defense Technology and located at the National Supercomputing Center in Tianjin, has a processing power equivalent to 175,000 laptop computers, according to Nvidia officials. With sustained performance reaching 2.5 petaflops, this Chinese supercomputer, named Tianhe-1A, is 30% faster than the world's second most powerful supercomputer at Oak Ridge National Laboratory in Tennessee, as per Nvidia's claims. The Tianhe-1A will serve scientists in various fields and will also be available for international use. Nvidia, known for its high-end video cards favored by gamers, is now promoting its technology for diverse applications beyond graphics, including supercomputers that run complex simulations in astrophysics and other computation-heavy tasks.

Canada released its Cybersecurity Strategy this month, emphasizing the immense challenge of protecting government and corporate computer systems. “There is no simple way to detect, identify, and recover from attackers who cannot be seen or heard, who leave no physical evidence behind them, and who hide their tracks through a complex web of compromised computers.” The $90 million (Canadian) strategy focuses on three main areas: Secure government systems : The government will implement the necessary structures, tools, and personnel to fulfill its cybersecurity obligations. Create partnerships to secure non-governmental systems : In cooperation with provincial and territorial governments and the private sector, the government will support initiatives to enhance Canada's cyber resiliency, particularly in critical infrastructure sectors. Help Canadians be secure online : The government will provide Canadians with the information they need to protect themselves and the...

Today's cybercrime has far-reaching implications for security professionals. Corporate environments are increasingly targeted, with intellectual property becoming a primary focus for criminal activity. According to Uri Rivner, head of new technologies, identity protection, and verification at RSA, this trend was highlighted during a roundtable at the RSA conference in London this week. Rivner explained that in the past, cybercrime was often a one-man operation—typically a basement hacker causing mischief. Nowadays, it has evolved into an entire economy, run like legitimate businesses with a few key exceptions. "Online fraud is divided into two parts—harvesting and cashing out," he said. "This means those who steal and collect the data and those who monetize it by using the stolen credentials." Launching a Trojan attack has become remarkably easy. Rivner noted, "A Trojan costs around $700, with the famous Zeus Trojan priced at $3,000. An adware system cos...

The difference between cyber crime, cyber espionage, and cyber war is often just a matter of a few keystrokes, as they use the same techniques. Richard Clarke, chairman of Good Harbor Consulting, highlighted this during his keynote at the RSA Europe 2010 conference in London. Cyber Crime Cyber crime is not just a theory; it happens every day. Clarke explained that just two weeks ago, there were arrests of a cyber cartel in the US. However, those arrested were students acting as mules. These mules simply open a bank account and allow money to flow in and out of it, being the lowest level in the cyber crime hierarchy. Clarke elaborated that these cartels are often based in Moldova, Estonia, Belarus, or Russia. After lengthy investigations involving warrants to search computers and servers, crimes are traced back to these countries. However, cooperation from these countries is often nonexistent, making them effective cyber sanctuaries. As long as attacks happen outside their borders an...

A US court has found two Russian hackers guilty of bank fraud, involving over $1.3 million. The investigation revealed that the fraudsters broke into computer systems of various companies and used the obtained banking data to steal money from their bank accounts. Authorities believe the fraudsters were part of a larger gang that recruited Russian youngsters. These individuals opened bank accounts where the stolen funds were transferred. The Russians then withdrew the money and distributed it among their accomplices. The verdict will be delivered in 90 days. The two convicted criminals, 25-year-old Dmitry Krivosheev and 24-year-old Maksim Illarionov, face fines of about $250,000 and prison sentences of up to 20 years. The third accused, 25-year-old Aleksey Petrov, was released. This case is not an isolated incident. Recently, six other Russian youngsters were accused of a significant computer hacking scam against US banks. Some received fines, while others were sentenced to six month...
