DeltaPrime, iVest, and Spectra Finance Lose $1.25M to Storage Collisions, Burn Abuse, and Call Injection
iVest let token burns distort price, Spectra Finance exposed wallets to arbitrary call execution, and DeltaPrime misaligned storage across upgrades, letting an attacker seize ownership. Three bugs, same lesson: validation is not optional.
In Brief
iVest suffered a $172K price manipulation attack.
Spectra Finance was targeted in a $73K attack.
DeltaPrime lost $1M due to an unauthorized ownership transfer.
Hacks Analysis
iVest | Amount Lost: $172K
On August 12th, the iVest exploit on the BNB chain resulted in a $172K loss due to a price manipulation vulnerability. The root cause of the exploit was that the attacker was able to burn the iVest tokens, reducing the total supply and artificially increasing the token price. The attacker first borrowed WBNB through flash loans and swapped the funds for iVest tokens. The attacker then executed the private _makeDonation() function which burned iVest tokens and reduced the total supply. The attacker then sold the iVest tokens at an artificially inflated price and made a profit.

Exploit Contract (on BNB): 0x786fcf76dc44b29845f284b81f5680b6c47302c6
On July 24th, the Spectra Finance exploit on the Ethereum mainnet resulted in a $73K loss. The root cause of the hack was the absence of proper input validation in Spectra Finance’s Router contract, specifically in the execute() function. The attacker drained tokens from four individual wallets by executing the private _dispatch() function with the kyberRouter and targetData variables. The Spectra Finance team acknowledged the incident and restored operations.
On July 23rd, the DeltaPrime exploit on the Arbitrum chain resulted in a $1M loss. The attacker exploited a misconfiguration to gain unauthorized access to 13 DeltaPrime contracts. They transferred ownership of these contracts to their address and repaid loans to withdraw collateral. The breach was facilitated by a critical oversight where both implementations checked for the _initialized flag, but did so using two different storage slots. This discrepancy allowed the attacker to manipulate the system by taking control of the contract initialization which allowed him to configure some variables to his will. DeltaPrime confirmed the exploit and offered a 10% bounty to the attacker for recovery of the funds.

The rich text element allows you to create and format headings, paragraphs, blockquotes, images, and video all in one place instead of having to add and format them individually. Just double-click and easily create content.
A rich text element can be used with static or dynamic content. For static content, just drop it into any page and begin editing. For dynamic content, add a rich text field to any collection and then connect a rich text element to that field in the settings panel. Voila!
Headings, paragraphs, blockquotes, figures, images, and figure captions can all be styled after a class is added to the rich text element using the "When inside of" nested selector system.
Follow-up: Conduct a follow-up review to ensure that the remediation steps were effective and that the smart contract is now secure.

Huobi | Amount Lost: $8M
On September 24th, the Huobi Global exploit on the Ethereum Mainnet resulted in a $8 million loss due to the compromise of private keys. The attacker executed the attack in a single transaction by sending 4,999 ETH to a malicious contract. The attacker then created a second malicious contract and transferred 1,001 ETH to this new contract. Huobi has since confirmed that they have identified the attacker and has extended an offer of a 5% white hat bounty reward if the funds are returned to the exchange.
