Furucombo Biweekly Update #15

It has been three weeks since our last newsletter, so much happened during the period and we finally have time to wrap it up and share the whole story with you.

In this newsletter, we will not cover new combo strategies, instead, we will outline what happened during an exploit that occurred on Saturday 27 February 2021, and our follow-up plans.

TL’DR: We have stopped the attacker, patched the vulnerability, and finalized the mitigation plan for all affected users (22 addresses).

Except that, we will kick-off a new COMBO mining campaign this Thursday to incentivize COMBO holders and supporters. Check out the details below!

# Furucombo’s Update

✅ Furucombo Post-Mortem March 2021

A sophisticated attack was launched on Furucombo, resulting in a loss of funds. We are doing everything we can to learn from this experience to make sure it doesn't happen again.

What happened during the exploit? The attacker drained funds from 22 users who had approved Furucombo’s proxy with an unlimited token allowance. We patched the vulnerability in an hour to stop the attacker. We also redeployed a new proxy contract and reset the default ERC-20 token amount of approval on Furucombo - the token amount of approval will be exactly the amount spent.

We would like to reassure you that all user funds are safe and the hacker cannot use the same method to attack again, and we are collaborating with several audit firms, including Certora, to re-examine the platform before we launch new features. For the 22 affected users, we will issue 5M iouCOMBO tokens with a 360-day linear-vesting period as compensation.
