Developers of the Montero crypto currency have eliminated a bug that could allow intruders to "burn" funds in organizations' wallets, while sacrificing only a modest amount in the form of transaction commissions. This is reported in the official announcement of the project: https://getmonero.org/2018/09/25/a-post-mortum-of-the-burning-bug.html.
The created fix was privately distributed to exchanges and large merchants, so as not to attract unnecessary attention to the time of elimination of problems. According to the developers, to perform real attacks, the exploit was not used.
