Really stupid “smart contract” bug let hackers steal $31 million in digital coin – Ars Technica

https://arstechnica.com/information-technology/2021/12/hackers-drain-31-mil… Blockchain startup MonoX Finance said on Wednesday that a hacker stole $31 million by exploiting a bug in software the service uses to draft smart contracts. The company uses a decentralized finance protocol known as MonoX that lets users trade digital currency tokens without some of the requirements of traditional exchanges. “Project owners can list their tokens without the burden of capital requirements and focus on using funds for building the project instead of providing liquidity,” MonoX company representatives say here. “It works by grouping deposited tokens into a virtual pair with vCASH, to offer a single token pool design.” An accounting error built into the company’s software let an attacker inflate the price of the MONO token and to then use it to cash out all the other deposited tokens, MonoX Finance revealed in a post. The haul amounted to $31 million worth of tokens on the Ethereum or Polygon blockchains, both of which are supported by the MonoX protocol. Specifically, the hack used the same token as both the tokenIn and tokenOut, which are methods for exchanging the value of one token for another. MonoX updates prices after each swap by calculating new prices for both tokens. When the swap is completed, the price of tokenIn—that is, the token sent by the user—decreases and the price of tokenOut—or the token received by the user—increases.

whooo! it's 16:15 on 2021-11-24 and i know that well because i just typed a spamlogtiny where i found the broadcast rpc call for libretchingandvomiting and ... then my xorg began misbehaving such that only the menu bar would respond to keyboard and mouse input, no matter what window was focused, and then i wrote a script to dump the memory of my chrome processes, and the visible email content didn't seem to be in the memory i dumped, and then my system ran out of space, and my body froze up and started spasming ... basically when my computer gets a corruption i start thinking aliens are hacking my brain and everything goes wrong. but then i rebooted the system! the email was apparently lost, _but_ i have part of a script started for dumping process ram, so that's progress for future situations. in my imaginary world where i can do free makery stuff, i use a field probe to read the ram directly from its refresh emissions using an sdr. but we are not in this imaginary world so i use /proc/[pid]/mem and /proc/[pid]/maps . it would be good to set the kernel settings that let me use /dev/mem, be super helpful. anyway ! libtotallygrossdestroyedwaste is still seeming fun to pursue. there's also a thing in an hour i'd kinda like to try going to. my new scared habits know to hit 'save draft' over and over and over again to make life make more sense. it's 16:55 and i'm hitting 'save draft'. 16:57 i hit 'save draft' again. and here i go again. i like hitting it. in electrumx, transaction_broadcast() expects a hexadecimal string passed, and it's called in response to 'blockchain.transaction.broadcast' yay! it's 16:58 and i'm hitting 'save draft'. it's 17:00 and ................ the rpc call source reads like it would return the transaction hash after broadcast. i'm hitting save draft! it's 1701 ! 1703. omigod i wrote a broadcast wrapper! it's a 1-line function and it's so hard. i know it won't work yet (because my error density is so high) but here it is: async def broadcast(self, txbytes) -> str: return await self.request(str, 'blockchain.transaction.broadcast', txbytes.hex()) woohoo ! saving draft. and code. ok ummmm i'll use the op_return code to test it. i'll use my mobile phone to send money to a private address. the hardest part will be making the private key because th eop return code uses a local node. maybe i'll just focus on that. it's 1718. hitting 'save draft'. what a nice, friendly button. now it's 1719. anyway i've made a possible opreturn output, pending bugs. the biggest concern around craftin ga transaction is estimating a fee. maybe i'll make a quick fee estimation wrapper. 1719. i better wrap other useful things too like getting utxos. and that will mean identifying an address by its 'hashx', an electrum-specific thing. 1726 how to get a hashx is at https://github.com/spesmilo/electrum/blob/8d7370d897314d8542906aecc6a45cc94… def address_to_scripthash(addr: str) -> str: script = address_to_script(addr) return script_to_scripthash(script) or in electrumx in coin.py class Coin def address_to_hashX(cls, address): '''Return a hashX given a coin address.''' return cls.hashX_from_script(cls.pay_to_address_script(address)) 1728 1732. i guess i'll be going to my event to stay more stable. maybe switchin' gears.
