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%.

This Monday, the Chinese mining company Bitmain announced the next-generation 7-nm chip codenamed BM1397, which, according to it surpasses its predecessors in performance and energy efficiency and is suitable for mining cryptocurrencies on the SHA256 algorithm, including Bitcoin and Bitcoin Cash.

The BM1397 chip requires less energy and is able to achieve efficiency at 30J / TH, which is “higher by 28.6% than the previous 7-nm chip from Bitmain”, codenamed BM1391.

BM1397 is manufactured using TSMC, a Taiwan-based semiconductor product company, which is one of the leading suppliers in the cryptocurrency mining industry.

The BM1397 chip will be installed in the new ASIC miners of the Antminer S17 and Antminer T17 models, the release of which Bitmain promises to announce later. The company does not provide other details of the updated devices in its message.
