The New York Times, the Wall Street Journal, Financial Times and some other newspapers have published articles indicating that cyber attacks targeting Google and several other U．S．companies were from China．Such accusations are biased（有偏见的）．
These articles take as evidence that hackers’ IP addresses could be traced back to two schools in China．However, it is common sense that hackers can attack by controlling computers from anywhere in the world．This fact also explains why hackers are hard to be tracked down．
Computers in China are easy to be controlled by hackers as the majority of Chinese Internet users lack security awareness and adequate protection measures．
The hackers’ IP addresses could by no means vindicate（证明正确）the newspapers’ accusations that the attacks were carried out by Chinese citizens or from within China．
The New York Times says one of the schools from which the cyber attacks were said to originate has military support．Another school “has received financing from a high-level government science and technology project．”
The New York Times went to great lengths to mention that “graduates of one of the school’s computer science department are employed by the local military each year．” The paper, however, did not care to tell its readers that a school in China does not need to have any special relationship with the military to have its graduates in uniform．It is also true in the United States, where the New York Times is based．
China’s attitude toward cyber attacks has been unequivocal and has adopted laws against such crimes, as China is one of the countries that suffer from cyber attacks．
The U．S．government, on the other hand, takes an uncertain attitude toward cyber attacks．According to media reports, the U．S．Homeland Security and Defense departments have both openly employed hackers．
People with a “blackhat perspective” and knowing how to “do threat modeling” are the best choices, said Philip Reitinger, Department of Homeland Security deputy undersecretary, at an information security conference last October．
Cyber crimes could cause immense losses to individuals, companies and nations．Effective supervision(监督) and closer international cooperation are ways to improve cyber security．Finger pointing is not．
