On November 9, a statement appeared in Netta Lab’s Twitter account that the organization discovered a vulnerability in the Ethereum virtual machine that allows you to endlessly execute smart contracts without paying for gas online. The researchers also allegedly turned to the operator of the American database of vulnerabilities, where they registered the corresponding discovery.

At Netta Lab's request, Google can find the site of the netto.io project, which specializes in auditing smart contracts under the Netta Lab brand, but the Twitter accounts of the projects do not match. Note that the profile that reported the vulnerability was registered in November.

Many users expressed doubts about the authenticity of the information that appeared, but then the creator of the NEO project Da Hongwei said that he spoke with the CEO of Netta Labs and asked the researchers to audit the NEO virtual machine.

“I spoke briefly with [Netta Labs]. The vulnerability looks pretty serious , ”he stressed.

Nevertheless, Vitalik Buterin on Reddit wrote that this is a vulnerability in the Python-implementation of the virtual machine, which was first written on GitHub 9 days ago. This means that the main clients (go-ethereum; parity and cpp-ethereum) do not affect the problem.

Add that on Friday evening, Bitcoin developer Matt Odell also reported a potential vulnerability in the Ethereum protocol, which threatens funds on cryptocurrency exchanges.

The dApp developer Level K was the first to announce the risks for the infrastructure of some platforms, but details have not yet been disclosed.

Recall hardfork Constantinople in the main network Ethereum supposedly held January 16, 2019.
