K9 Finance has made a new bounty offer to the Shibarium bridge hacker, and Shiba Inu ecosystem stakeholders are urging the exploiter to take the deal this time.
“Grab free cash before the offer expires this time,” lead developer Kaal Dhairya urged in his Tuesday tweet. He encouraged the exploiter to do the right thing and take the increased bounty offer for the stolen KNINE tokens.
New Improved Offer from K9 Finance
Notably, Dhairya lent his voice to spotlight the new offer from K9 Finance, a staking affiliate of the Shiba Inu ecosystem. The platform called November 3 a “lucky day” for the Shibarium bridge hacker, as it offered an improved 20 ETH bounty to return the exploited KNINE tokens.
Dear Shibarium Bridge Hacker,

Notably, this marked a 300% increase from the earlier 5 ETH offered to the hacker. Notably, K9 Finance made the original offer a few days after the September 12 flash loan attack, noting that it would start to decay in five days.
An on-chain message from K9 developers highlighted that the 5 ETH bounty was above the standard 10% bounty offered to white-hat hackers. However, the hacker failed to respond even after the Shiba Inu ecosystem team added 50 ETH to return all stolen assets.
Now, K9 Finance has offered 20 ETH to the hacker. The project shared the bounty contract, urging the hacker to review the source code and approve the bounty to spend the KNINE tokens. Recall that K9 Finance has blacklisted and frozen the tokens but cannot retrieve them; hence, the negotiation.
Hacker Responds
Interestingly, the Shibarium bridge hacker has now responded for the first time since the hack. On Tuesday, the hacker dropped an on-chain message urging K9 Finance to increase the offer to 50 ETH to recover all KNINE tokens.
The attacker stole 248 billion KNINE, worth over $717,000 at the time of the hack and $340,256 now. At the current market price, 50 ETH is worth $165,150, meaning the hacker wants a staggering 48.5% of the stolen fund’s value.
Notably, the hacker has liquidated some of the stolen funds. Specifically, he converted some USDT and USDC to Ethereum. Late in September, he sold all stolen BAD tokens for 3.2 ETH through MetaMask.
Shiba Inu Has Tightened Security
Meanwhile, the Shibarium bridge has resumed activity despite users still feeling the impact of the hack. Developers have also recovered 4.6 million BONE tokens linked to the hack through the StakeManager.
Going forward, the ecosystem developers have promised a tighter security measure to ensure that a similar event does not occur. They migrated over 100 contracts across Shibarium, Shiba Inu Metaverse, and ShibaSwap to multi-signature wallets and introduced a blacklist feature to block malicious accounts from participating in staking activities.
