This situation has escalated with demands from the purported ethical hacker responsible for the exploit, who is insisting on a public apology and the unveiling of the Prisma Finance team before considering the return of the stolen funds.
The focal point of the breach was identified in two MigrateTroveZap contracts designed for transitioning user positions between trove managers.
Despite efforts to address the exploit, a core contributor known as “Frank” emphasized the ongoing risk to five accounts with open trove positions, collectively at risk of losing over $500,000.

Prisma Finance utilizes “troves,” or Ethereum addresses, for users to manage loans.
The most vulnerable account is reported to hold $484,380, with the remaining four accounts holding between $7,120 and $22,080.
In response to this crisis, Prisma outlined a “path forward” that includes measures to safeguard additional reserves while striving to recoup the pilfered assets.
A proposal introduced on April 1 aims to diminish liquidity from POL and vePRISMA staked revenue as part of these recovery efforts.

In a bold move, the hacker, claiming to be a “white hat” ethical hacker, criticized Prisma Finance for their alleged lack of due diligence and has laid out specific conditions for the return of the funds.
These conditions include a public session where the Prisma team must fully disclose their identities, acknowledge their errors in auditing the smart contracts, and outline plans for enhanced security measures.
The hacker’s demands highlight a contentious debate over the responsibilities and ethics involved in the aftermath of the exploit.
Following the exploit affecting a number of users individual vaults, Prisma Protocol has been paused by the emergency multisig and remaining funds are safe. mkUSD and ULTRA, as stablecoins, are overcollateralized and are not at risk.

Prisma’s retort underscores skepticism about the hacker’s intentions, noting the absence of any returned funds as a gesture of good faith.
The incident has had a profound impact on Prisma Finance, with its total value locked plummeting from approximately $220 million to $87 million.

This ongoing saga not only sheds light on the vulnerabilities within DeFi platforms but also raises critical questions about accountability, security practices, and the path to restitution following such exploits.
