The miner wasn't hidden - it had to sent XMR to user's wallet, but sent it to scammer's wallet instead

In the Google Play app store, an application for the Monero mining with a "defect" was found. Monero Miner successfully coped with the stated task and really mined the crypto currency, using for this purpose the computing power of the Android devices, but their owners did not become richer from it. This is reported ESET antivirus company.

The thing is that mined XMR coins were send to the scammers addresses, not user's. 

The general mining fever helps scammers. Some of them hide the function of mining in their mobile applications for hidden mining using the users' devices. Others, on the contrary, specifically develop applications to deceive novice miners.

To date, the application has been removed from Google Play. Before that, up to 50,000 users could install it. 

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.
