Polygon, an Ethereum-based network, has “silently fixed” a vulnerability that compromised its native MATIC tokens valued at $ 24 billion (approximately Rs.178,560). The problem came to light after a group of ethical hackers informed Immunefi, a bug bounty platform related to decentralized funding (DeFi). Immunefi hosts the bug bounty for the polygon network. Despite quick measures to resolve the case, notorious hackers were able to steal 801,601 MATIC tokens, which corresponds to about 2.4 million US dollars (approx. 17.8 billion rupees).
The vulnerability was identified in Polygon’s Proof-of-Stake (PoS) Genesis contract. The network has provided an “Emergency Bor Upgrade” to remedy this vulnerability.
“The upgrade was performed on December 5th in block # 22156660 without affecting the liveliness or performance of the network in any way. The vulnerability has been fixed and the damage has been reduced without causing any material damage to the protocol and its end users. All Polygon contracts and node implementations remain completely open source, ”says Polygon’s official blog.
The network also released a Twitter update on the fix.
