Abstract:Smart-contract audit company CertiK has been awarded the sum of $500k by Sui Foundation for the discovery of a potential attack vector on the Sui network.

Smart-contract audit company CertiK has been awarded the sum of $500k by Sui Foundation for the discovery of a potential attack vector on the Sui network.
The firm discovered a vulnerability that a malicious smart contract can trigger, leading to an endless circle for the blockchains nodes, and paralysis of the network.
According to a press release from CertiK on June 19, the HamsterWheel attack is different from traditional attacks that shut down chains by crashing nodes. Instead, it works like something running on a hamster wheel by trapping all nodes in a state of ceaseless operation without processing new transactions.
It is capable of crippling entire networks and eventually making them inoperable. Chief security officer at CertiK, Kang Li, said that “the discovery of the HamsterWheel attack demonstrates the evolving sophistication of threats to blockchain networks”.
The Sui Foundation revealed that the identification of the bug will enable a team of developers to install two main measures capable of reducing the possible effect of a similar issue in the long run. They have rolled out fixes for the bug and a full technical report will be published later, said CertiK

CMC MARKETS presents a mixed picture for forex traders, earning a moderate overall rating of 6.4 out of 10 based on 228 reviews and a "Use with Caution" designation.

These positive attributes are reflected in the sentiment distribution, where 150 reviews were positive compared to just 47 negative ones, suggesting that many traders have had satisfactory experiences with the platform. However, the 20.6% negative rate cannot be ignored, as it highlights recurring concerns that potential clients should carefully consider.

No, we are not kidding! The rupee has indeed hit this low, from 90 to 95 against the US dollar, the fastest in nearly a decade, highlighting the slump due to rising crude oil prices and global uncertainty from the series of adverse events related to the geopolitical conflict in the Middle East. It just took five months for the rupee to weaken from 90 to 95, the sharpest five-point depreciation since the 2013 taper tantrum. During this period, the rupee declined from 60 to 65 within a month amid concerns over India’s current account deficit and large capital outflows.

While it was a flat day for India’s benchmark stock indices (Sensex & Nifty), there was a sort of recovery for the rupee in the foreign exchange market on May 21, 2026.
