Sun explains that during the period needed to upgrade to version 4.1 the Mainnet was attacked by a malicious smart contract, at 06:14 Hong Kong this morning.
The attack would have been able to use the authority of the developer of the contract, so much so that the attacker initiated malicious transactions causing the suspension of block production decided by the Super Rep.
Sun also reveals that the attacker was hoping to profit from this block production suspension, and that the Tron community responded immediately, identifying the problem and resolving it immediately by working with the Super representatives to update the nodes.
In fact, already at 08:29 the Mainnet gradually resumed the production of blocks, and finally returned to normal at 9:40.
Sun also defines Tron as „the decentralised network with the highest resilience and defence against attacks in the industry“, but to tell the truth today it does not seem to have proved to be so.
First of all, the stop to the production of blocks, and therefore to transactions, decided by the Super Representative is not really a sign of great decentralisation. Moreover, the fact that the vulnerability was probably contained in the update, or in the update procedure, does not seem to reveal a particularly high level of security.
It must be said, however, that in the past, other blockchain platforms with smart contracts, such as the Bitcoin Machine Review itself, were also victims of attacks in some ways similar to this one.
The Tron connection weighs on the TRX
The price of Tron’s native cryptocurrency, Tronix (TRX), has suffered a consequence due to the fear generated by this attack.
In fact this morning it has fallen suddenly from 25,64 thousandths of dollar to 25,04, that is a loss of 2,3% in less than an hour, to then fall further to 25,02.
In fact, it has been suffering a little bit for about a week, since on 29 October it was worth 27.23 thousandths of a dollar. In a few days she lost 8%. The price however is still largely higher than that of beginning of year, when it was around 19,6 thousandths of dollar.
