New malware can literally destoy users' devices while mining XMR

Trend Micro, a company specializing in cyber security, reports a new type of malware for Android.

When installed, Malware will mine Monero using the smartphone processor until it exhausts all resources or the mobile device does not break.

In the code of HiddenMiner there is no controller, switch or optimizer, it constantly mines the Monero, right up to the mobile device overheating.

If the researchers' warnings are correct, this is not the first malicious software that can kill your smartphone: last year there was a case when Loapi Android malware exploited device so hard that the smartphone its battery swelled and cracked the back of the device, destroying the mobile device within 48 hours.

Trend Micro reports that the new malware has some similarities with Loapi. With the help of HiddenMiner, one of its operators produced 26 XMRs - about $ 5,360 - from one of the wallets.

HiddenMiner is an application on Google Play and forces users to activate it as a device administrator.

It will constantly appear until the victim presses the "Activate" button; after granting permission, HiddenMiner will start minning Monero in the background.

It is difficult to delete a miner, it blocks such user actions.

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.
