Defi Platform Cream Finance Hacked, $29 Million Lost

Cream

Cream finance, a defi borrowing and lending protocol, has been the victim of a hack that erased more than $29 million from its vaults. The attacker took advantage of a loophole in the implementation for adding the amp token to the protocol. This is the second time the platform has been involved in a hack. The first breach happened in February, when Cream lost $37.5 million.

Cream Protocol Suffers Hack

Cream protocol, a defi lending-borrowing platform present on four different chains (Ethereum, BSC, Polygon, and Fantom), suffered a hack Monday that resulted in the loss of $29 million in several cryptocurrencies. The attacker took advantage of a bug caused by the introduction of the amp token into the protocol. According to Peckshield, a blockchain security and data analytics company, the hack was perpetrated in just one transaction, taking advantage of a reentrancy bug present in the code of the amp currency.

This allowed the hacker to re-borrow assets during the transfer before updating the first borrow. The exploit was repeated 17 times and allowed the hacker to get ahold of 418,311,571 amp (worth $25.1 million) and 1,308.09 ethereum (worth $4.15 million). The platform had been audited by Trails Of Bits, a cybersecurity research and consulting firm, prior to the inclusion of the amp token.

Cream declared it stopped the exploit by pausing supply and borrow on amp. The protocol also informed users that no other markets were affected, and that it was expecting to offer a post mortem report at a later date.

Not the First Time

This is not the first time Cream has suffered a hacking incident. Less than six months ago, the platform was also affected by a hack that allowed the attacker to withdraw $37.5 million. The hack, using an unreleased version of a contract of Alpha Finance, another defi protocol, exploited a rounding miscalculation in the code and a whitelisting function. After taking control of the funds, the attacker took them to Tornado.cash, a protocol that allows private transactions in Ethereum.

Luckily, no user funds were affected during this first hack. However, it shows that the defi environment is very complex and that even a small change in protocol (like adding a currency or whitelisting another platform) can have a big impact on security in the future.

Fidelity Discusses Bitcoin as Portfolio Insurance — Could Soon Stand in ‘Stark Contrast’ to Path Fiat Currencies Take

Fidelity Digital Assets, a subsidiary of Fidelity Investments, says that bitcoin could be considered portfolio insurance. The firm notes that the cryptocurrency “may soon stand in stark contrast to the path that the rest of the world and fiat currencies may take — namely the path of increased supply, additional currency creation, and central bank balance sheet expansion.” Fidelity Says Bitcoin Could Be Portfolio Insurance Fidelity Digital Assets, a subsidiary of Fidelity Investments, recently published a research study titled “The Rising Dollar and Bitcoin.” The research outlines “how bitcoin could be considered portfolio insurance” as the rising dollar impacts global currency markets. “The strengthening U.S. dollar is wreaking havoc among other countries and may put pressure on the Federal Reserve to soon reverse its tightening monetary actions, something that has precedent based on 1985’s Plaza Accord,” Fidelity explained. In addition, “more monetary debasement may be needed to ...

Economists Discuss Russia, China Potentially Developing Gold-Backed Currency That Could Undermine US Dollar

Economists have weighed in on reports that China and Russia may be developing a new gold-backed currency that could undermine the U.S. dollar’s status as the world’s primary reserve currency. Russia and China May Be Developing Gold-Backed Currency Several experts have shared their views on Russia and China potentially creating a new gold-baked currency, Fox Business reported Saturday, emphasizing that China has been buying up huge quantities of gold while Russia was forced off the U.S. dollar due to sanctions imposed on the country following its invasion of Ukraine. The news outlet noted that some experts have cautioned that these moves, along with the closer relationship that has developed between Moscow and Beijing, point to the likelihood of China attempting to launch a gold-backed currency. However, neither Russia nor China has officially confirmed plans for such a currency. Craig Singleton, senior fellow at the Foundation for Defense of Democracies and a former U.S. diplomat,...
