More than $150 meg has been lost this calendar week in separate security breaches at DeFi projects MonoX and BadgerDAO.

Multi-chain decentralized commutation (DEX) MonoX (MONO) suffered a cyber attack on Tuesday leading to nigh $31 million in losses. BadgerDAO (Annoy) suffered a front end-end attack that was discovered on Th with estimates of Badger'southward losses striking more than $120 million.

The MonoX DEX platform suffered a single attack on Tuesday. In this assault, a bug in the smart contract allowed for a discrepancy to exist between prices of avails when manually changed.

Rekt News explained that hackers were able to inflate the price of MONO via the smart contract, and so purchase up other assets from the protocol with MONO.

"The hacker created a loop in which the price of tokenOut would overwrite the cost of tokenIn, pumping the cost of MONO over the form of many "swaps.'"

The MonoX squad confirmed as much in a Tuesday tweet. In a postmortem published on Th, total losses were confirmed at nearly $31 million. The team added:

"Days like yesterday are horrible, there is no sugar coating the harsh reality of a contract beingness exploited and people losing money. Our supporters put their organized religion in a new project like the states, and yesterday we allow them down."

MONO listed on Huobi only 5 days before the hack on MonoX.

The Badger security breach was an ongoing threat to users interacting with Annoy DAO's platform rather than a single large exploit.

Discord users began reporting unusual spend requests from the Badger platform and alerted admins on social media and on Discord as early as Saturday.

Admin Blackbear responded that the request was unusual, but probable caused by a beneficial bug in the front-end user interface (UI).

The bug in the UI turned out to be the malicious attacker attempting to steal funds from that user'southward withdrawal. The same tactic would exist used on random users for days or even weeks earlier it was discovered equally a security breach.

At time of writing, losses from the Badger set on amounted to over $120 million, including 2078.76 BTC, thirty.27 ibBTC, and 151.32 ETH, according to blockchain analytics company PeckShield. The Badger team has been investigating the issue and has paused all smart contracts on the protocol to avoid any further losses.
