Il solito, bravo e ben informato, David Sanger ha pubblicato un articolo sul New York Times dal quale tra le righe traspare, a mio modesto avviso, l’effettivo ruolo del governo americano nel recente rapporto della Mandiant e, più in generale, la sua strategia di contrasto nei confronti del cyber-spionaggio “made in China”:

When the Obama administration circulated to the nation’s Internet providers last week a lengthy confidential list of computer addresses linked to a hacking group that has stolen terabytes of data from American corporations, it left out one crucial fact: that nearly every one of the digital addresses could be traced to the neighborhood in Shanghai that is headquarters to the Chinese military’s cybercommand. That deliberate omission underscored the heightened sensitivities inside the Obama administration over just how directly to confront China’s untested new leadership over the hacking issue, as the administration escalates demands that China halt the state-sponsored attacks that Beijing insists it is not mounting.[…]
Defining “enemies” in this case is not always an easy task. China is not an outright foe of the United States, the way the Soviet Union once was; rather, China is both an economic competitor and a crucial supplier and customer. The two countries traded $425 billion in goods last year, and China remains, despite many diplomatic tensions, a critical financier of American debt. As Hillary Rodham Clinton put it to Australia’s prime minister in 2009 on her way to visit China for the first time as secretary of state, “How do you deal toughly with your banker?” In the case of the evidence that the People’s Liberation Army is probably the force behind “Comment Crew,” the biggest of roughly 20 hacking groups that American intelligence agencies follow, the answer is that the United States is being highly circumspect. Administration officials were perfectly happy to have Mandiant, a private security firm, issue the report tracing the cyberattacks to the door of China’s cybercommand; American officials said privately that they had no problems with Mandiant’s conclusions, but they did not want to say so on the record. That explains why China went unmentioned as the location of the suspect servers in the warning to Internet providers. “We were told that directly embarrassing the Chinese would backfire,” one intelligence official said. “It would only make them more defensive, and more nationalistic.”[…]
In the next few months, American officials say, there will be many private warnings delivered by Washington to Chinese leaders, including Xi Jinping, who will soon assume China’s presidency. Both Tom Donilon, the national security adviser, and Mrs. Clinton’s successor, John Kerry, have trips to China in the offing. Those private conversations are expected to make a case that the sheer size and sophistication of the attacks over the past few years threaten to erode support for China among the country’s biggest allies in Washington, the American business community.

In altre parole, sempre secondo il sottoscritto, Washington – tramite la “copertura” (più o meno consapevole) di società private (in questo caso la Mandiant) e senza esporsi ufficialmente – indica il governo cinese come vero responsabile delle operazioni cyber a danno delle aziende americane. Ciò sia a fini di consenso interno (policy di cyber-security) che nell’ambito di un dialogo con la stessa Pechino.
