SAN FRANCISCO, April 4 (Xinhua) -- Web exploit toolkits, or " packaged" attack frameworks that can be traded online, are rapidly growing as the top cybercrime weapon due to ease of use and high success rate, a new report has found."When it comes to conducting online crime, exploit toolkits are the weapon of choice for many cyber criminals," said the "2010 Top Cyber Security Risks Report" published by Hewlett-Packard Co. (HP) on Monday.The trend started in 2006 with the release of WebAttacker, considered by many to be the first modern day web exploit toolkit, according to the report.An emerging trend ensued and soon took off, and today the Internet is subjected to hundreds of exploits originating from these toolkits."With the ever-increasing, web-based criminal activity, the number of exploit toolkits has skyrocketed and shows no signs of slowing down," the report stated.Though protecting against attacks originated with web exploit toolkits is becoming increasingly difficult, there are ways to minimize the risk of infection, said the report, noting that one of the most effective defenses is to install patches onto host systems.The report also found that while the number of attacks against known vulnerabilities continues to rise, the number of discovered vulnerabilities has plateaued in 2010."We've discovered that rather than investing resources to uncover new exploits, attackers are focused on current, unpatched vulnerabilities in web applications, social networking sites and Web 2.0 interfaces," Mike Dausin, a manager at HP Digital Vaccine Labs, said in a statement.Data from the report showed that nearly half of all reported vulnerabilities exist in web applications, and third-party plug- ins to content management systems have become the leading cause of web application vulnerabilities.

BEIJING, May 24 (Xinhuanet) -- CT scan, a widely used heart-imaging test, is likely to result in the over treatment for patients with heart disease, according to a study published online by the Archives of Internal Medicine on Monday.CT, which produces a detailed image of the heart that reveals cholesterol buildups in the coronary arteries, is widely used in the hospital around the world."Testing might lead to more harm than good," said McEvoy, a doctor at Seoul National University Bundang Hospital in S. Korea.His team led the study, in which 2,000 healthy adults were divided into two groups. One thousand adults had CT scans and another half had standard tests, including routine checks of their blood pressure and cholesterol levels.After 18 months, the 215 people who had worrisome CT scans were advised to have additional tests and medical treatment, and some even advised to have surgery. But less than 10 percent in the group of standard test were reported to need medications.Therefore, physicians cannot easily ignore the diagnoses made by the new imaging techniques, McEvoy said, "We are left with the dilemma of what to do with the results,"According to McEvoy, doctors should focus on patients' lifestyle and traditional risk factors such as smoking and obesity.

BEIJING, Feb. 13 (Xinhua) -- Chinese State Councilor Meng Jianzhu left here Sunday for visits to the Democratic People's Republic of Korea (DPRK), Laos, Singapore and Malaysia.Meng, who is also Chinese Minister of Public Security, is traveling to the countries at the invitation of the DPRK Minister of People's Security Ju Sang Song, Lao Minister of Public Security Thongbanh Seng-aphone, Singaporean Minister for Home Affairs and Minister of Law K Shanmugam, and Malaysian Minister of Home Affairs Hishiammuddin Tun Hussein.

JERUSALEM, May 8 (Xinhua) -- Israeli researcher Jacob (Koby) Scheuer, from the Tel Aviv University (TAU) School of Electrical Engineering, has developed a nano-scale gyroscope, the Ha'aretz daily reported Sunday.Scheuer developed a new optic-fiber nano-sensor four years ago, along with an optic gyroscope that works in conjunction with the sensor. As he developed the devices, it occurred to him that his discovery could be harnessed to surgical needs, virtual reality, or communications, said the report."What we developed here is an optic gyroscope," Scheuer told Xinhua in a recent interview on Sunday, "like the others, but the breakthrough is that we found a way to measure rotation in a very, very small device using the optic sensor."Optic gyroscopes emit light when they rotate, and change its wavelength when there is any change in the speed of rotation, making it possible to measure velocity and position by the differences in light.Scheuer's gyroscope, however, is so small in comparison to the others commonly used in planes, trains and vehicles, that it can be used in cell phones or watches and does not need satellite connection like the ubiquitous Global Positioning System.The applications of this gyroscope and optic sensor are almost endless, as Scheuer puts it."It can be a pill that you swallow and can move through your body to take pictures or release drugs in a localized area," the researcher explained, "or it can be used by a doctor to operate on a patient who is thousands of kilometers away.""Our gyroscope has complete independent navigation capability, which the others don't have," he stressed.Though the new optic gyroscope works in theory, it still hasn't been tried in out in reality. "It will take some time until we can empirically demonstrate our work, I would say about three to five years," Scheuer added.Alongside the gyroscope, Scheuer continues to work on the optic sensor, whose applications can also be found in security, such as an information security system developed by Scheuer to safeguard online information that acts as a key bearer."When both parties have 'the key' it's virtually impossible to hack the information sent," Scheuer noted, terming the development as a "total paradigm change."

HARARE, Feb. 9 (Xinhua) -- The two-day visit to Zimbabwe by Chinese Foreign Minister Yang Jiechi starting Thursday is an endorsement of relations between the Southern African country and China, local figures told Xinhua.Former Zimbabwean ambassador to China Chris Mutsvangwa said in an interview on Tuesday that Yang's visit will also boost economic relations between the two countries."The visit of a foreign minister is a big banner announcement to say that relations between Zimbabwe and China are reaching for a new level," he said."This is a visit which will mark a new diplomatic high watermark in Zimbabwe's international relations because to get the visit of an important and emerging super-power like China with such economic clout is a big vote of confidence on the part of Zimbabweans who have been pummeled by sanctions" imposed by the West.Yang, who will make the visit at the invitation of Zimbabwean Foreign Minister Simbarashe Mumbengegwi, is scheduled to meet President Robert Mugabe and other senior government officials.Mutsvangwa said the Chinese veto at the United Nations in 2008 was "a landmark diplomatic decision where it basically saved Zimbabwe from punitive sanctions instigated by an irate and sulky former colonial power.""So, now this visit will give an opportunity for Zimbabweans tofinally thank China for this act. But more important, cooperation in the economic field is beginning to gather pace because we have crossed the diplomatic and political travails which have been going on in the last 10 years and come out more united because the Chinese veto also enabled Zimbabweans to find accommodation among themselves and led to the GNU and GPA," Mutsvangwa said.China, together with Russia, vetoed the British initiative for full-scale UN sanctions against Zimbabwe, saying the Southern African Development Community (SADC) and the African Union (AU) should be given a chance to resolve the country's political problems.A SADC-driven initiative led to a Government of National Unity (GNU) following the signing of the Global Political Agreement (GPA) between Mugabe and then rivals Prime Minister Morgan Tsvangirai and Deputy Prime Minister Arthur Mutambara."So there is more national unity now among Zimbabweans. It is an opportune moment for us to tighten our relations with China so that we can explore cooperation in the more rewarding material areas of agriculture, mining, tourism and industrialization."There is clearly a lot of scope for cooperation between Zimbabwe and China so that Zimbabwe can quicken its modernization pace taking advantage of the stellar achievements of the Chinese in the above areas," Mutsvangwa said.He cited areas such as telecommunications, international logistics and the internet as being led by the Chinese.China Tobacco has also been on the fore-front reviving tobacco farming in Zimbabwe for the past five years.Mutsvangwa said shortages in the global cotton sector could spur better trade relations between the two countries and lead to more opportunities for Zimbabwean farmers.
