Casper Network Contains Crypto Hack

The Casper Network team detected a crypto hack, which led to the temporary closure of several parts of the system. Validators locked down transactions at block 3,329,418 era 14544, disallowing any more transactions, including transfers, minting, or even staking.

Casper Network’s official communication channels assured its community that the breach is contained and under active investigation. Once everything is settled, details about the breach will be provided.

In accordance with their telegram group, an exhaustive post-mortem report will be published, and any relevant code changes on Casper’s GitHub repository will be available for everyone.

Limited Account Impact and Community Response

This breach only impacted on very few major accounts- this is reportedly widely known. The nature of this particular attack and extent of damage are still being determined; however, all necessary actions have been taken by Casper Network to ensure malicious activities elsewhere do not affect users’ accounts any further.

Trading in $CSPR (the native cryptocurrency for the platform) continues on exchanges despite halting blockchain activities. This move ensures liquidity and continuity for token holders while the network resolves security issues. 

Efforts towards addressing and fixing this problem are being put in place through a committed participation by validators and developers among others within the wider Caspar community.

Crypto Community Hack Concerns

This incident on the Casper Network is among several recent security concerns in the broader cryptocurrency community. For example Scroll network’s lending protocol called Rho Markets recently closed due to suspicious activity linked with an Oracle control vulnerability. In this case, the attackers accessed without permission pools like USDC paired with USDT worth about $7.6million distributed over multiple chains.

WazirX, an Indian cryptocurrency exchange, has suffered a massive blow from hackers in the month of July. WazirX implemented a user compensation and recovery plan after this incident, which spread the losses among users using a unique 55/45 model. This strategy was aimed at providing users with immediate access to most of their holdings while they worked on further recovery solutions.

Meanwhile, the Casper (CSPR) price has plummeted significantly, falling to its three-week low. During the dip, CSPR price swayed between an intra-day high and low of $0.02144 and $0.01851, respectively. At press time, CSPR was trading at $0.01948, a 8% decline from the 24-hour high.
