Huawei Mate 20 series comes with lots of new features and it’s powered by the flagship Kirin processor that provides immense multi-tasking and can also handle heavy tasks executions. The phone also loads a new Matrix camera system for the high-quality camera system.

In the past, Huawei Mate 20 device owners enjoyed continuous software support but now in the latest ride of this story, Huawei Mate 20 models have also received the latest EMUI 11 across China and countries across the globe.

The EMUI 11 brings a number of new features that enhance system performance and enables a better user interface for an improved user experience.

As we discussed before, not every user is satisfied with EMUI 11 upgrade because of the bugs and issues that it may bring to a few models. For example, a Huawei Mate 20 Pro user recently contacted us and informed us about a nasty bug that appeared on his smartphone following the upgrade on EMUI 11.

According to the user, after upgrading to EMUI 11.0.0.138 version, the phone started to show black screen flickering once the user starts to interact with the user interface and refreshes the whole background process. Because of this, most of the apps became inaccessible due to the continuous screen UI refresh.

The user also revealed that he can only access 6 out of 223 apps on his phone because of this issue. However, we believe that issue likely to appear only in a few models compared to a large number of device owners.

To solve this issue, we recommended the user to back up the data and roll it back to the EMUI 10.1 via using the HiSuite app on PC or Mac. Then try to upgrade again to EMUI 11 via the HiSuite with a proper installation.

Check the video below for more information about the issue.

Huawei Cloud

An advanced version of crypto-mining malware has been found lately that could be a serious threat to Huawei Cloud and users. This malware was previously reported attacking the open-source software development platform- Docker Containers.

As per the report, this new malware version has enough algorithms to dodge the firewall rules creation function. Adding to this, it leaves a network scanner behind to track API-relevant ports of the other hosts.

However, this new crypto-mining malware is currently active in cloud environments. Furthermore, it’s checking for the other ecosystem that has previously been affected by this attack.

Before discussing its other details, let’s first know what crypto-mining is-

What is Crypto-mining :

Crypto-mining or Cryptojacking is defined as an online thread or malware that holds the ability to hamper and even crash an organization’s digital environment. In addition, it worked while staying completely hidden from a user.

In Cryptojacking, the attacker can use the victim’s devices without their concerns to secretly mine cryptocurrency. Likewise, it also causes financial losses for the victim and disruption to business workings. Moreover, it mainly targets cryptocurrencies or digital money.

On a Linux system, this digital currency miner malware has to follow a procedure shown in the figure. It not only harms the system but simultaneously removes its traces.

Afterward, it replaces all users added by the other actors with the one created by them. It’s one of the basic steps follows by the cloud-targeting cryptojackers. Unlike other attackers, the cryptojackers use the Sudo programs in their accounts that provide root access to the system.

Furthermore, the attacker uses their own sh-RSA key to perform system adjustments and change the file permissions to a locked state. It restricts other users to get entire control of the vulnerable computer or device even if they gain access to the device.

Besides, the actors install the Tor proxy service that helps them in preventing from establishing a connection to other network scanning detection. For wrapping, there are binaries codes (linux64_shell, ff.sh, fczyo, xlinux) at UPX packer. Once the attack get complete control of the device, it began to execute its malicious activities.

However, there are some known vulnerabilities detected during the scan in this attack. Most of them are related to the weak password in some functions that includes

Some Known Vulnerabilities:

  1. SSH weak passwords
  2. Vulnerability in the Oracle WebLogic Server product of Oracle Fusion
  3. Middleware (CVE-2020-14882)
  4. Redis unauthorized access or weak passwords
  5. PostgreSQL unauthorized access or weak password
  6. SQLServer weak password
  7. MongoDB unauthorized access or weak password
  8. File transfer protocol (FTP) weak password

As you can see, what users can if on Huawei Cloud if this coin-mining malware has been surfed in actual. To be mention, all the describe info came from the leading data security and cybersecurity solution provider TrendMicro.

According to this firm, it has sent the acknowledgment report to Huawei Cloud to make the authorities aware of the crypto-mining malware. Now, we are waiting for Huawei to officially address this problem.
