The US government is encouraging American companies to launch their own cyberattacks against criminal hackers, a move that certain US media claimed would bring the US closer to the practices of some of its chief cyber adversaries, including China and Russia. A Chinese expert slammed the claim as factually unfounded, saying that the US move would seriously disrupt the global cyberspace order. Washington has long projected its own conduct onto other countries, inventing adversaries to justify the militarization of cyberspace, the weaponization of artificial intelligence (AI) and even a privateer-style model of cyber piracy, said the expert.
Under a national security memorandum that US President Donald Trump signed late Wednesday, select companies would work with the Justice and Homeland Security Departments to strike foreign cybercriminal groups with hacks under certain conditions. The attacks would allow both surveillance of the criminal networks and specific types of hacking operations that could lead to disruption, manipulation or destruction of information systems and networks, including virtual and physical infrastructure, according to a report from the New York Times.
A CNN report called the move "a major policy shift that experts say could come with legal risk for the companies." It also noted that "companies can use cyber tools to surveil foreign criminals and disrupt their networks under the 'control and oversight' of the new federal program."
The US move is an attempt, under the guise of combating cybercrime, to accelerate its plan to issue "cyber privateering licenses" to private entities. Its core objective is to exploit its advantages in the cybersecurity and intelligence sectors and rapidly turn AI-enhanced cyberattack capabilities into tools for securing strategic interests and undermining the security of other nations, Xiao Xinguang, chief software architect from Chinese cybersecurity company Antiy, told the Global Times on Friday.
Analysts noted that some US media outlets routinely drag China into the frame and slander it whenever Washington unveils relevant policies, all to manufacture pretexts to legitimize America's own policies.
The New York Times report claimed that "to some extent, the new order would align the US more with some of its chief cyberantagonists, including China and Russia, where spy agencies have long relied on contract hackers working in the private sector to further their national security missions."
Xiao noted that the US has long projected its own practices onto other countries, manufacturing imaginary adversaries as scapegoats and falsely attributing to China the operational models of its own intelligence agencies, contractor networks and revolving-door system. By applying double standards and leveling unfounded accusations, Washington creates pretexts for militarizing cyberspace, weaponizing AI and even developing a cyber-privateering model.
In reality, certain US corporations have long supported US intelligence agencies in intelligence collection and offensive cyber operations, and this has been an established practice for years, Xiao said.
"Now, the US is bringing these previously covert practices into the open. As the trend develops, more US cybersecurity firms and intelligence contractors could operate under so-called privateering authorizations, posing as non-state actors while carrying out intrusions, data theft, sabotage and other disruptive cyberattacks against countries around the world," said Xiao.
。作为概念验证，研究人员最近用3D打印了一些饼干，这些饼干外表光滑，看起来很正常，但内部却有一个空隙的图案。虽然这些图案在正常照明下看不到，但当从后面照明时，从正面看饼干，它们就会显示为“剪影的窗户”。然后，一个普通的智能手机能够读取这些代码，显示出其中存储的数据。不用说，在其目前的形式下，该技术将被限制在相对较薄、有点半透明的3D打印食品中使用。

二 | 尽管如此，科学家们希望它最终能够为制造商、零售商和消费者提供一种替代方法，以取代更浪费、更昂贵的方法，如常规应用于水果的纸质标签，或应用于包装的RFID标签。此外，如果成分和营养成分等信息可以由食品本身转达，那么就需要更少的包装来显示相同的数据。“我们的3D打印方法是食品数字化转型的一个很好的例子，我们希望这将改善食品的可追溯性和安全性，”该研究的高级作者佐藤浩介说。
