阿根廷官方公报遭到黑客攻击,显示出虚假的冠状病毒决议

2020-3-22 15:46

 

据《El Cronista》报道,3月14日,阿根廷官方公报遭到黑客攻击,显示出虚假的冠状病毒决议。官方公报使用区块链系统,这是众所周知的具有挑战性的黑客。


这些错误的出版物包括有关已确诊或疑似病毒感染的国家雇员和在家工作的公务员的决议。截至撰写本文时,阿根廷已确诊128例冠状病毒病例,并已宣布在该国强制隔离。


政府宪报以某些方式刊登公众或法律公告,例如政府行政当局的报纸。在阿根廷,电子版的官方公报和印刷版的公报一样,在法律上是有效的。


在当前的全球卫生危机中,防止虚假信息是各国政府避免恐慌的首要任务之一。这次黑客攻击与上周六版的不正确版本的出版有关。


但究竟发生了什么似乎是个谜。


一位不愿透露姓名的消息人士告诉《El Cronista》:“没有人进入或改变任何东西”。这名人士还暗示说,这次攻击造成了异常高的流量,导致网站瘫痪了几个小时。


另外,该报称,错误的分辨率仍然可见,并在第二天上传了一个更新的正确版本。这可能意味着区块链系统上的信息可能被篡改,而不仅仅是网站。


如果这个网站被黑了,虚假的版本可能很快就被删除了。区块链是一个不可变的分类账,没有修改或更改数据的规定,这可能解释了需要一个补充版本。这就是为什么必须验证进入区块链的数据,以便它仍然是“真相”的单一来源。El Cronista说,虽然决议中的信息是假的,但这是一个有效的决议,表明一个节点一定是被入侵了,或者有人上传了假信息。


虽然关于区块链系统的确切细节还不清楚,但几乎可以肯定的是,它是经过私人许可的区块链。私有区块链的节点数量有限,一些或所有的节点都可以在区块链上进行写操作。因此,有可能是一个这样的节点被黑了,或者是一个未经授权的人获得了访问权限。


阿根廷正在探索区块链的各种治理角色,并建立了区块链联邦阿根廷(BFA)。最近,该公司推出了利用区块链在国内分销天然气的Gasnet。阿根廷暂停了区块链公司的注册,理由是需要加强监管控制。

On March 14, Argentina’s Official Gazette suffered a hack with false Coronavirus resolutions displayed, reported El Cronista. The Official Gazette uses a blockchain system, which is known to be challenging to hack. 

The false publications included resolutions relating to state employees that have confirmed or suspected virus infections and public servants working from home. Argentina has confirmed 128 Coronavirus cases at the time of writing and has announced mandatory quarantine in the country. 

A government gazette publishes public or legal notices in some ways like a newspaper of the government administration. In Argentina, the digital version of the Official Gazette is considered legally valid, just as the printed copy. 

With the current global health crisis, preventing false information is one of the top priorities for governments to avoid panic. The hack related to the publication of the incorrect version of last Saturday’s edition.

But precisely what happened seems to be a mystery.

An unnamed source told El Cronista: “No one entered or changed anything”. The same person implied there was an attack that generated unusually high traffic that took the website down for hours. 

Separately, the newspaper stated that the false resolution was still visible alongside an updated correct version uploaded the next day. This may imply the information on the blockchain system could have been tampered with, and not merely the website. 

If only the website were hacked, the false version could have been deleted quickly. Blockchain is an immutable ledger, with no provision to amend or change data, which might explain the need for a supplemental edition. That’s why it’s essential to verify the data that goes onto a blockchain so that it remains a single source of “truth”. El Cronista said that while the information in the resolution was false, it was a valid resolution, indicating that a node must have been compromised or someone with access uploaded false information. 

While exact details about the blockchain system are not available, it’s almost certainly a private permissioned blockchain. Private blockchains have a limited number of nodes, with some or all having access to write on the blockchain. So, it is probable that one such node with permission to write to the blockchain was hacked or an unauthorized person gained access. 

Argentina is exploring blockchain for various governance roles, and has set up the Blockchain Federal Argentina (BFA). Recently, it launched Gasnet for leveraging blockchain for natural gas distribution in the country. Argentina suspended the company registration blockchain, citing the need for increased regulatory control.
