Developers of MyMonero wallet published a JavaScript library for desktop and browser versions of the product.

New features:

  • Desktop: Fixed a critical issue in previous release due to insufficient testing where Contact records would not be loadable after first save (this was due to emojis being incorrectly encoded in the encryption library). If you have any Contact records which can't be loaded, please delete them from the app in the Edit modal, and add the contact info again.
  • Desktop: Added built-in software update functionality
  • Added web wallet support for Firefox after locating runtime crash on webkit CSS rule insert
  • Added support for incoming new generated_locally flag and server-supplied start_height to ensure that the correct Import Transactions button visibility persists across successive logins
  • A few minor UX and security improvements
  • Web wallet footer

The desktop application is a lightweight wallet and does not require the user to download the entire Monero blockchain.

Earlier XMR Wallet announced the successful completion of an external security audit.

Monero Team to Kill Coin Burning Bug

A scenario of a hypothetical attack described by one of the participants of Monero's subreddit helped to identify the bug

Developers of the Monero cryptocurrency have eliminated a bug that could allow intruders to "burn" funds in organizations' wallets, while sacrificing only a small amount in the form of transaction commissions. This is reported in the official announcement of the project.

A scenario of a hypothetical attack described by one of the participants of Monero's subreddit allowed to identify the bug.

Practically speaking this bug is exploited as follows. An attacker first generates a random private transaction key. Thereafter, they modify the code to merely use this particular private transaction key, which ensures multiple transactions to the same public address (e.g. an exchange's hot wallet) are sent to the same stealth address. Subsequently, they send, say, a thousand transactions of 1 XMR to an exchange. Because the exchange's wallet does not warn for this particular abnormality (i.e. funds being received on the same stealth address), the exchange will, as usual, credit the attacker with 1000 XMR. The attacker then sells his XMR for BTC and lastly withdraws this BTC. The result of the hacker's action(s) is that the exchange is left with 999 unspendable / burnt outputs of 1 XMR.

Monero developers note that this method does not allow the attack organizer to directly receive the XMR coins deposited in this way. However, an attacker can withdraw XMR through bitcoins, and the exchange will remain with 999 non-consumable or "burned" outputs from 1 XMR.

The created fix was privately distributed to exchanges and large merchants, in order not to attract unnecessary attention to the time of elimination of problems. According to the developers, the exploit was not used to perform real attacks.

In early August, because of the critical bug in the code of Monero, which allows to manipulate the amount of transactions, Livecoin suffered losses exceeding $ 1.8 million.
