Specialists in the field of cyber security have discovered a new botnet, which instead of malicious actions searches and destroys hidden mining malware. This is reported by CoinDesk.

Botnet called Fbot is a variation of the Satori, which in turn is based on the Mirai program. The latter is often used for DDoS attacks. However, in the case of Fbot, the module for DDoS attacks is deactivated and replaced by the device search function with the software installed for hidden mining.

The new botnet was investigated in detail by the Qihoo 360Netlab team. As noted in their blog, Fbot is looking for a malicious program called com.ufo.miner, which is a variation of the Monero miner called ADB.Miner. The latter is aimed at devices under the Android operating system.

The program is distributed through open ports, and then deletes com.ufo.miner if it finds it. Fbot is programmed to scan the network, spread over it, install over malicious software, and then self-destruct.

It is noteworthy that the botnet uses a decentralized alternative to EmerDNS instead of the standard Domain Name System (DNS). Because of this, the address is harder to track and close.

The choice of Fbot using EmerDNS other than traditional DNS is pretty interesting, it raised the bar for security researcher to find and track the botnet (security systems will fail if they only look for traditional DNS names).

It is not yet clear whether Fbot was created with good intentions, or to eliminate competitors in the market.

According to Trend Micro researchers, during the first half of 2017, the number of cases of unauthorized cryptomoney detection increased by 956%.

The creator of Ethereum, Vitalik Buterin, published on GitHub a proposal on changing the reward scheme for validators after the transition of ETH to the Proof-of-Stake consensus mechanism (PoS).

According to the formula proposed by Buterin, if PoS-validators, for example, validate 1,000,000 ETH, then the annual yield will be 18.1%.

The more assets are fixed for validation, the lower the interest rate. So, 134 217 728 ETH will bring cryptoinvestors only 1.56% per annum. At the same time, the maximum annual emission volume will be 2,097,152 ETH.

Considering that the current volume of Ethereum's market offer is 105,777,585 ETH, this offer is focused on the medium and long term. Buterin also clarified that the profitability indicators are shown without taking into account proceeds from transaction fees. Consequently, the actual income of validators can be several percent higher than the values ​​indicated in the table.

According to Justin Drake, a researcher at the Ethereum Foundation, if after implementing PoS 32 million ETH will be allocated for stacking, the income of validators will be 3.2% per annum. At the same time, the annual emission indicator will be 1% (for comparison, the current indicator of Bitcoin inflation is 3.94%).

In this case, Drake notes that after the activation of EIP 1559 of the funds collected in the form of commissions, will be destroyed. Consequently, with an average gas consumption of each shard of 1000 ETH per year, inflation will drop to 0.5%.

Users left generally positive comments on the offer. However, some of them expressed fears that in the new conditions the exchange may receive significant advantages, which will be able to do stacking at the expense of clients.
