Reader Briefing

Tectonic, a lending platform on the Cronos network, suffered an economic attack where hackers manipulated the price of Tonic tokens to borrow 74 million dollars in digital assets.

•Hackers manipulated Tonic token prices 300-fold within 20 minutes to use them as collateral on Tectonic.
•Cronos network operators froze all blockchain transactions, limiting actual losses to 6 million dollars.
•PeckShield identified the cause as a risk configuration vulnerability allowing a single data source to determine loan approvals.
•The attack occurred during a period when Cronos had recently failed business negotiations with a company owned by former President Donald Trump in early August.

Overview

•Hackers exploited a risk configuration vulnerability in Tectonic by inflating the price of Tonic tokens 300 times in 20 minutes to use as collateral.
•The attack led to the borrowing of 74 million dollars in digital assets, causing Tectonic's deposited assets to drop from 122 million dollars to 3 million dollars.
•Cronos network operators temporarily froze all blockchain transactions to stop the movement of assets.
•The emergency freeze limited the actual amount moved via bridges to Ethereum to 6 million dollars.
•Kris Marszalek, CEO of Crypto.com, confirmed that customer funds on the centralized exchange are safe.
•Crypto.com is working with Cronos Labs to attempt a state rollback of the blockchain to a point before the incident.
•The price of the CRO token fell 1.4% to 5 cents, resulting in a market value of approximately 2.74 billion dollars.
