Morgan Stanley: GPU mining sales will fall in 2018

Joseph Moore, analyst at Morgan Stanley published a report with a forecast for 2018: GPU manufacturers can lose up to 50% of sales revenue

Analyst of American banking holding Morgan Stanley Joseph Moore published a report with a forecast for 2018 on the decline in sales of video cards, which could adversely affect the financial performance of AMD and Nvidia. This is reported by CoinDesk.

Among the factors contributing to the drop in revenue from the sale of powerful videocards, the analyst pays attention to a decline in the overall block reward on the ethereum network, from 5 to 3 ETH. In general, Moore is confident that in the corresponding segment the largest manufacturers of videocards can lose up to 50% of sales revenue.

We believe that total graphics sales for ethereum mining in 2017 will be $800 [million] or so, and will decline by 50% in 2018; we can validate the 2017 number by looking at the increased complexity of the algorithm. Unless ethereum prices rally, downside variance to our 2018 forecast is more likely than upside.

Two weeks ago, Joseph Moore published a AMD video cards sales forecast, reducing his value from "neutral" to "negative". According to the analyst, despite the fact that the company managed to get super profit for some time due to the avalanche demand for video cards for mining, this trend is unlikely to continue in the future.

Exim Mail Servers to Undergo Massive Attacks

Hackers are using fixed vulnerability, which was found last week, but still more than 3.6M mail servers in the global network remain potentially vulnerable

Cybereason security researchers warned mail server administrators about the discovery of a massive automated attack that exploits a critical vulnerability (CVE-2019-10149) of Exim that was discovered last week. During the attack, hackers seek to execute their code as root and install malware for mining cryptocurrency on the server.

According to the Shodan service, more than 3.6 million mail servers in the global network remain potentially vulnerable, and are not updated to the latest release of Exim 4.92. About 2 million potentially vulnerable servers are located in the USA, 192 thousand in Russia. According to RiskIQ, version 4.92 has already switched 70% of servers to Exim.

Administrators are advised to urgently install updates that were prepared last week (Debian, Ubuntu, openSUSE, Arch Linux, Fedora, EPEL for RHEL / CentOS). If there is a defeated version of Exim in the system (from 4.87 to 4.91 inclusive), you need to make sure that the system is no longer compromised by checking the crontab for suspicious calls and to ensure that there are no additional keys in the /root/.ssh directory. The attack can also be indicated by the presence in the log of the firewall of activity from the hosts an7kmd2wp4xo7hpr.tor2web.su, an7kmd2wp4xo7hpr.tor2web.io and an7kmd2wp4xo7hpr.onion.sh, which are used for during the malware download process.

The first attacks on Exim servers were recorded on June 9th. By June 13, the attack became widespread. After exploiting the vulnerabilities through the tor2web gateways, the Tor hidden service (an7kmd2wp4xo7hpr) downloads a script that checks for OpenSSH (if not installed), changes its settings (allows root login and key authentication) and sets the root user for the root user access to the system via SSH.

After setting up the backdoor, a port scanner is installed in the system to identify other vulnerable servers. It also searches the system for existing mining systems that are deleted if detected. At the last stage, the own miner is loaded and registered in the crontab. The miner is loaded under the guise of an ico-file (in fact, is a zip-archive with the password "no-password"), in which the executable file in ELF format for Linux with Glibc 2.7+ is packed.
