Huawei P30 Pro is one the best smartphone that was released in 2019 and is the best camera flagship that is ever released by any smartphone maker at that timespan. If we talk about these devices, we can only say one thing – Marvellous!
From its 6.47-inch curved edge OLED panel to the Kirin 980 power center as well as the rear quad-camera system, it allows users to take mesmerizing photos with high-quality as well as Huawei P30 Pro dominates all sections.
That’s not it because it comes with a large 4200mAh battery that supports faster charging at a capacity of 40W featured with Huawei’s SuperCharge technology. Before we dive into our topic, I want to point out the device’s software capabilities.
The Huawei P30 Pro comes with pre-built EMUI 9.1 and the company took good care of the consumers by sending two more major upgrades including the EMUI 10.0, EMUI 10.1, and then EMUI 11.0.
The latest version of EMUI, EMUI 11 comes with a new set of features including smart always-on display (AOD), smoother animation effects in the user interface, and more usability through the latest tweaks made throughout the software system.
EMUI 11 surely brings a number of new improvements for the Huawei P30 Pro and it’s currently expanding for different regions around the globe. However, issues and bugs have no time and date to appear because they just occur and software updates may have the uncertainty of bringing them especially major upgrades.
Now, coming back to the topic, there a number of users that reported on Reddit that they’re facing a most common problem with most probability after any upgrade, Battery draining.
According to a Reddit user, the Huawei P30 Pro is consuming more power installing EMUI 11 and mentioned that it wasn’t the case on EMUI 10. In reply to this, some other users pointed out the same mistake, while others mentioned that their units started to provide good battery backup after a few days of using EMUI 11.
Still, the number of users reporting this problem is very limited and not everyone has the same complaints but recently, the Chinese consumers of the P30 Pro stated their encounter with such an issue.
We don’t have any insights into why this issue is occurring but we definitely think it could be related to software optimization. Still, we recommend users switch with a compatible USB and install the EMUI 11 OTA with interruption.
So, it’s time that we hear from you and get your feed on this matter. Are you facing a battery issue on your Huawei P30 Pro after upgrading to EMUI 11? Let us know in the comments.
An advance cryptomining malware could be a threat to 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:
- SSH weak passwords
- Vulnerability in the Oracle WebLogic Server product of Oracle Fusion
- Middleware (CVE-2020-14882)
- Redis unauthorized access or weak passwords
- PostgreSQL unauthorized access or weak password
- SQLServer weak password
- MongoDB unauthorized access or weak password
- 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.
HarmonyOS October security update resolves input verification issue
Huawei has released the October security 2021 patch that soon rollout for eligible smartphones and tablets running on HarmonyOS. This monthly update fixes several known issues and vulnerabilities to resolve the improper behavior of the devices.
While exploring the patch details, we have come to know about a serious issue that can cause injection attacks, memory leakage, and compromised application. However, the HarmonyOS October 2021 security release note will fix this issue in the affected devices. You can check the basic details below-
- Affected Sector: Applications
- CVE: CVE-2021-37116
- Description: It’s an input verification vulnerability
- Impact: Successful exploitation of this vulnerability may affect the data confidentiality and product availability
The input verification issue with high severity is only affecting the devices working on HarmonyOS 2.0 system. The device infected will this issue, accepts improper data or information while receiving data from an external party especially from untrusted sources.
An attacker can intentionally send malicious input into the system. Meanwhile, the affected devices aren’t able to verify the authenticity of the data and take it. It causes an application to carry out some unplanned action such as data leakage or confidential information exposers.
Moreover, the attackers relay malicious code through an application to another system that accepts it due to holes in input verification algorithms. Luckily, as the latest HarmonyOS security patch will be released for the devices, this input verification issue will be fixed.
Besides, the security update also acknowledged 2 medium levels of CVE in the framework, 2 high and 4 medium levels CVEs in the kernel, and 1 high and 5 medium to low-level system threats. In addition, 2 critical, 3 high and 6 medium levels security threats fix in the HarmonyOS 2.0 applications.
Huawei fixed a dangerous Bluetooth bug in September 2021 update
With the release of the September 2021 Security Patch details, Huawei highlights the bugs and their fixes for the Huawei and Honor devices. It’ll fix various issues in the system alongside a Bluetooth bug that could harm a user in several ways.
The latest security patch includes a medium-level bug fix identity as CVE-2021-37039 on the smartphones running on EMUI 11.0.0, EMUI 10.1.1, Magic UI 4.0.0, Magic UI 3.1.1 Android skins. Once an attacker successfully exploits cross this Bluetooth bug, it may cause a serious Bluetooth DoS.
What is Bluetooth DoS:
The Bluetooth system in any device can be the mean of DoS (Denial of service) attracts and cloud seriously harm the victim. In BT DoS, the attacker or hacker frequently requests to pair the target’s Bluetooth device with his in order to access the personal info of the soon-to-be victim.
However, Huawei has timely recognized this flaw and release the patch fix. Once it reaches the device holders, they will get input verification notice before their device is paired with the other. It’ll help them to avoid intruders.
In simple words, when someone wants to establish a BT connection with users, the device will ask for the owner’s permission before connecting the other device. If the second user is a known person, you can accept the request and can grant the permission. Furthermore, you can also deny it, if you don’t know the origin of the second device.
Although Huawei has released the patch details, the company hasn’t started the rollout process. It’s still releasing the June and July security patches not to talk about the August security release. Until the patch is available to the users, they can try to avoid enabling their BT, while not in use.
