Simple vulnerability in smart contract software allows hacker to steal $ 31 million worth of digital currency

Published

An accounting error in MonoX Finance’s software allowed an attacker to raise the price of the MONO token.

Blockchain startup MonoX Finance has fallen victim to cyberattacks , during which a hacker stole $ 31 million. The cybercriminal took advantage of a vulnerability in the software that the platform uses to draft smart contracts.

The company uses the MonoX decentralized financial protocol, allowing users to trade digital currency tokens without the specific requirements of traditional exchanges. An accounting error in the company’s software allowed an attacker to raise the price of the MONO token and then use it to cash out all other deposited tokens.

The cyber attack used the same token as in tokenIn and tokenOut, which are methods of exchanging the value of one token for another. MonoX updates prices after each swap, calculating new prices for both tokens. When the swap is complete, the price of tokenIn (the token sent by the user) decreases and the price of tokenOut (the token received by the user) increases.

By using the same token for both tokenIn and tokenOut, the hacker increased the price of the MONO token significantly because the tokenOut update overwritten the tokenIn price update. The hacker then exchanged the token for $ 31 million worth of tokens on the Ethereum and Polygon blockchains. MonoX Finance management attempted to contact the attacker by sending a message via a transaction on the ETH mainnet. Recall that in October of this year, an unknown attacker hacked the Discord server of the Creature Toadz NFT project and tricked community members into sending him money. In total, the hacker managed to lure out more than 88 ETH from the victims (over $ 340 thousand at the exchange rate at the time of the crime). It is noteworthy that the hacker later returned all the money.

Nvidia lost LHR mining protection is also hacked under

Two days have passed since the NiceHash developers cracked the Nvidia LHR protection, as the NBMiner team also pleased their users with the same news. Only this time we are talking about software for Linux.

Thus, Nvidia’s protection completely fell for both Windows and Linux. Unfortunately, both programs are closed source, so it’s not clear what mechanisms the developers used to hack.

Whether the loss of Nvidia will affect the availability and prices of video cards is still difficult to say. At the moment, the cryptocurrency market continues to fall, but sooner or later it will turn around, and gamers may again face shortages and overpriced graphics cards.

These are machines for sucking out personal data Prayer and

Mental health apps have worse privacy protection than most other types of apps, according to a new analysis by Mozilla. We are talking about the entire category as a whole. In addition, things are also bad for prayer applications.

“These are machines for sucking out personal data.”  Prayer and mental health apps have poor security

The vast majority of mental health and prayer apps are exceptionally creepy. They track a variety of data, share and capitalize on users’ most intimate personal thoughts and feelings, such as mood, mental state, and biometric data.

The team analyzed 32 mental health and prayer apps. Of these apps, 29 received a Privacy not included warning, indicating that the team is concerned about how the app manages user data.

These applications collect large amounts of personal data in accordance with vague privacy policies. Most applications have also been found to have poor security practices that allow users to create accounts with weak passwords. Considering how much personal information such programs can contain, this is a bad feature.

The list of the worst programs according to the specified criteria included Better Help, Youper, Woebot, Better Stop Suicide, Pray.com and Talkspace. In particular, the Woebot chatbot claims to collect information about users and shares this data for advertising purposes, and Talkspace collects transcripts of user chats.

They work like data-sucking machines with the look and feel of a mental health app. In other words: wolves in sheep’s clothing
