Android malware spies while posing as a Update
New malware with extensive spyware capabilities steals data from infected Android devices and is designed to automatically trigger whenever new info is read to be exfiltrated. The spyware can only be installed as a 'System Update' app available via third-party Android app stores as it was never available on Google's Play Store. This drastically limits the number of devices it can infect, given that most experienced users will most likely avoid installing it in the first place. The malware also lacks a method to infect other Android devices on its own, adding to its limited spreading capabilities. However, when it comes to stealing your data, this remote access trojan (RAT) can collect and exfiltrate an extensive array of information to its command-and-control server. Zimperium researchers who spotted it observed it while "stealing data, messages, images and taking control of Android phones."

What happens when malicious software is installed

"Once in control, hackers can record audio and phone calls, take photos, review browser history, access WhatsApp messages, and more," they added. Zimperium said its extensive range of data theft capabilities includes:
  • Stealing instant messenger messages;
  • Stealing instant messenger database files (if the root is available);
  • Inspecting the default browser's bookmarks and searches;
  • Inspecting the bookmark and search history from Google Chrome, Mozilla Firefox, and Samsung Internet Browser;
  • Searching for files with specific extensions (including .pdf, .doc, .docx, and .xls, .xlsx);
  • Inspecting the clipboard data;
  • Inspecting the content of the notifications;
  • Recording audio;
  • Recording phone calls;
  • Periodically take pictures (either through the front or back cameras);
  • Listing of the installed applications;
  • Stealing images and videos;
  • Monitoring the GPS location;
  • Stealing SMS messages;
  • Stealing phone contacts;
  • Stealing call logs;
  • Exfiltrating device information (e.g., installed applications, device name, storage stats).

How does it work?

Once installed on an Android device, the malware will send several pieces of info to its Firebase command-and-control (C2) server, including storage stats, the internet connection type, and the presence of various apps such as WhatsApp. The spyware harvests data directly if it has root access or will use Accessibility Services after tricking the victims into enabling the feature on the compromised device. It will also scan the external storage for any stored or cached data, harvest it, and deliver it to the C2 servers when the user connects to a Wi-Fi network. Unlike other malware designed to steal data, this one will get triggered using Android's contentObserver and Broadcast receivers only when some conditions are met, like the addition of a new contact, new text messages, or new apps being installed. "Commands received through the Firebase messaging service initiate actions such as recording of audio from the microphone and exfiltration of data such as SMS messages," Zimperium said. "The Firebase communication is only used to issue the commands, and a dedicated C&C server is used to collect the stolen data by using a POST request."

Camouflage

The malware will also display fake "Searching for the update.." system update notifications when it receives new commands from its masters to camouflage its malicious activity. The spyware also conceals its presence on infected Android devices by hiding the icon from the drawer/menu. To further evade detection, it will only steal thumbnails of videos and images it finds, thus reducing the victims' bandwidth consumption to avoid drawing their attention to the background data exfiltration activity. Unlike other malware that harvests data in bulk, this one will also make sure that it exfiltrates only the most recent data, collecting location data created and photos taken within the last few minutes.

Fix Print Spooler Service Error 1068
There is one service in the Windows operating system that is responsible for managing all the print jobs as well as handles the interaction with the printer. This service is known as the Print Spooler service. However, if it stops running, then you won’t be able to print anything on your computer. In such a case, you can try to restart the Print Spooler service, and to do that, you have to open the Windows Services Manager and look for the Print Spooler Service. Once you found it, right-click on it and select Restart. If it isn’t running, select Start and if the Service starts working again, then good but if not and you got an error message instead that says, “Windows could not start the Print Spooler service on Local Computer, Error 1068, The dependency service or group failed to start”, then read on as this post will give you a couple of suggestions you can try to resolve the issue. The reason why you could not start the service is most likely because the Print Spooler service is dependent on other services which might not be properly running. If the following services are not running then it’s no wonder why you’re getting the error.
  • HTTP Service
  • Remote Procedure Control (RPC) Service
You might not see the RPC service which means that the Print Spooler Service does not recognize its dependency on the RPC service. In such a case, you have to manually configure the dependency by following the options given below.

Option 1 – Try configuring the dependency via CMD

The first thing you have to do is to configure the dependency using CMD. Refer to the steps below to do so:
  • Open an elevated Command Prompt.
  • Then type in “sc config spooler depend= RPCSS” and hit Enter.
  • After the command has been executed, restart your computer and then check if it fixed the problem. If not, proceed to the next given option below.

Option 2 – Fix dependency via the Registry Editor

You can also resolve dependency using the Registry Editor. How? Refer to these steps:
  • Tap the Win + R keys to open the Run dialog box.
  • Then type “Regedit” in the field and hit Enter to open the Registry Editor.
  • After that, navigate to this key: HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesSpooler
  • Next, right-click on the “DependOnService” entry located on the right pane and select Modify.
  • Now change its value data to “RPCSS” and click OK to save the changes made and then exit the Registry Editor.
  • Reboot your computer and see if the issue is resolved.

Option 3 – Try running the Printer Troubleshooter

Another option you can check out is the Printer Troubleshooter. This built-in troubleshooter in Windows 10 can help you fix most print issues. It checks if you have the latest printer drivers and then tries to fix and update them automatically. Aside from that, it also checks if you have connectivity issues or if the Print Spooler and the required Services are running fine. To run it, follow the steps below.
  • Tap the Win + R keys to open the Run dialog box.
  • Next, type “exe /id PrinterDiagnostic” in the field and click OK or hit Enter to open the Printer Troubleshooter.
  • Then click the Next button and follow the next on-screen instructions to fix the issue with the printer.

Fix Windows Activation Error 0xC004F212
Microsoft allows its users to download a copy of Windows to install on PCs. However, when you enter the key after the installation and you got the Activation Error 0xC004F212 instead, then it means that the license key and the Windows version you’ve just installed, do not match. When you encounter this error, you will see the following error message on your screen:
“The product key used on this PC didn’t work with this edition of Windows. Activation Error 0xC004F212.”
Every time Microsoft generates a license for a copy of Windows, it is associated with one particular Windows variant. Windows comes in many editions like Enterprise, Home, Professional, and so on. For instance, if you bought a license for Windows 10 Enterprise but you have installed Windows 10 Professional instead, then the activation will surely fail and you’ll encounter the Activation Error 0xC004F212. You will be asked to select which edition you want to install when you reinstall Windows 10 using a digital license. If you opted for an edition other than the one you are licensed to use, then you will most likely get the Activation Error 0xC004F212. If you have purchased your license key from a store or some website, you might want to check back with them about the exact version of Windows. Doing so will help you narrow down the problem. And if you have second thoughts about the license key’s validity, you can just reach out to a Microsoft Support agent to check the validity of the license key. Also, if have bought it from the store, there should be an option to get a refund. That way you can choose to buy the right version of Windows.

Option 1 – Try running the Windows 10 Activation Troubleshooter

The first thing you can do to resolve the Activation Error 0xC004F212 is to run the Windows 10 Activation Troubleshooter. To do so, follow these steps:
  • Go to Settings and then select Activation.
  • After that, click on the Windows Activation and then troubleshoot. This will help you address most of the commonly found activation issues in Windows devices.
The Windows 10 Activation Troubleshooter will determine if your license key is a valid Windows 10 digital license for an edition that is not currently installed. If it turns out that it’s not, then the troubleshooter will show you how to install the correct edition.

Option 2 – Try forcing Windows 10 ISO to use the right version

You can also try to force Windows 10 ISO to use the correct version depending on the product key. Note that this option only works between Windows 10 Home and Professional version since they both have a common ISO. So if it’s Enterprise, then this option won’t work for you.
  • Extract the Windows 10 ISO files using an extractor.
  • Then browse to the folder you created and go to the sources folder.
  • From there, you need to create a text file named “PID.txt” and make sure to follow the exact format given below:
[PID] Value=xxxxx-xxxxx-xxxxx-xxxxx-xxxxx
Note: “xxxxx” is the KEY to your Windows version.
  • Next, you need to create the ISO again or bootable media that will repack everything and then create the Media file. You can use the Media Creation tool for this.
Note: Windows will check the key during the installation and will figure out the right version of Windows.

Option 3 – Contact Microsoft Support for assistance

If you’re at your wits’ end in trying to update your Windows 10 computer, you should consider contacting Microsoft Support for help as they can offer you various options that would make fixing Windows Activation Error 0xC004F212 a lot easier and faster.

How to Fix Error Code 0x8007232B

Error Code 0x8007232B (Code 0x8007232B) – What is it?

Error code 0x8007232B (Code 0x8007232B) is an error that occurs when you attempt to activate Windows Server 2008 or Windows Vista.

Common symptoms include:

  • Attempting to activate Windows 7, Windows 8, or Windows Server 2012 and you receive an error message.
  • The error message says: “Windows could not be activated. Key management services host could not be located in domain name system, please have your system administrator verify that a KMS is published correctly in DNS”
  • The error message says “The directory name, file name, or volume label syntax is incorrect”.

Error Causes

  • Error Code 0x8007232B occurs when you attempt to use media that is volume licensed to install: Windows 8, Windows 7, Windows Vista Enterprise, Windows Vista Business, Windows Server 2012, Windows Server 2008, Windows Server 2008 R2.
  • This error code also occurs when the activation wizard is unable to connect to a Key Management Service host computer.

Further Information and Manual Repair

Error code 0x8007232B can be seen when you are trying to activate windows, on several different operating systems. This problem can usually be easily corrected, but in the event that it can't, please contact a computer repair technician. When you try to install any of the previously mentioned Windows products, they use a generic product key to install the volume-based license software. If you do have a KMS host computer configuration and see these error codes, that means the correct DNS entries are not being seen on the computer. If there is not a KMS host computer setup, you need to do this setup, otherwise switch to a MAK product key method, and activate the volume license installation that way.

Method One:

Using a Multiple Activation Key as opposed to KMS activation

  1. Click the Start icon, click on All Programs, click on Accessories, right-click on Command prompt.
  2. Click on “Run as administrator”. Type in the password or provide confirmation if prompted for administrator password or confirmation.
  3. When asked for the command prompt, enter in the following and then hit the Enter buuton: slmgr -ipk xxxxx-xxxxx-xxxxx-xxxxx-xxxxx  Note: this placeholder represents the MAK product key.

Method Two:

Configure a KMS host server for the clients to activate against.

A KMS host server needs to be configured for the clients to activate against. When there are no KMS host servers configured near you, install and activate a KMS server key. After this, configure a computer on the network to host this KMS software and publish the Domain Name System (DNS) settings.

Method Three:

When the client cannot locate a KMS host on the network for activation:

1. Verify that your computer has the KMS host installed and activated by using a KMS key that is registered in DNS. You will follow these steps to do that:

  1. Click the Start button, click on All Programs, click Accessories, and then right-click on Command Prompt.
  2. Click on Run as Administrator. Type the password or provide confirmation if you are asked for an administrator password or for confirmation.
  3. In the command prompt box, type the following command and press ENTER: nslookup -type=all _vlmcs.tcp>kms.txt
  4. Then open the KMS.txt file generated by this command. The file will contain at least one entry that relays the SRV service location.

2.  A KMS host server registers a DNS SRV record once every 24 hours by default. You should check the registry to see if the KMS host server is registering with the DNS. Follow these steps to do so:

  1. Click on Start, type in regedit, and then press Enter.
  2. Locate HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsNTCurrentVersionSL and then click on it.
  3. The KMS server does not register in DNS if the DisableDnsPublishing subkey is existing and has a value of 1. If this subkey is missing altogether, create a DWORD value called the DisableDnsPublishing. If the dynamic registration is suitable, the subkey value should be changed to 0. Right-click DisableDnsPublishing, click on Modify, enter 0 into the Value data box, and click OK.

Disabling Absolute Volume in Windows 10
As you know, Bluetooth headphones allow users to connect to their mobile devices wirelessly. This allows you to talk on your mobile device or listen to music without having to connect any cords or wires. Additionally, it even allows you to adjust the volume of a left or right speaker. However, Bluetooth headphones in Windows 10 are another story as their scope is limited. For instance, the left and right pieces can’t have different volume levels. But if you still want to change the dual control of the volume of headphones separately in Windows 10. And in this post, you will be guided on how exactly you can do that. In addition, in this post, you will also be guided on what you can do if the Windows Update messed with the Bluetooth volume control and what you can do to disable the absolute volume in Windows 10. In case you don’t know, the Absolute Volume feature is actually incompatible with a number of Bluetooth devices which can result in the inability of the Bluetooth device to adjust its volume. Thus, if you experience this kind of issue, you’ll notice that the volume slider in the taskbar and the device volume control neither have any effect in adjusting the volume. And each time you try to adjust the volume level for one speaker, the volume of another speaker also automatically changes. In such a case, it would be difficult for you to separately change the dual volume control headphones. Worry not for there is an easy registry tweak you can try to make this possible to do. But before you proceed with the instructions provided below, make sure that you create a System Restore first. Once you have that covered, follow the steps below carefully. Step_1: Tap the Win + R keys to open the Run dialog box and type “Regedit” in the field and hit Enter to open the Registry Editor. Step_2: Next, navigate to this registry path: HKEY_LOCAL_MACHINESYSTEMControlSet001ControlBluetoothAudioAVRCPCT Step_3: After that, look for the entry named “DisableAbsoluteVolume” which should be located in the right pane. But if you’re unable to find this entry, you can just create it by right-clicking on the CT key and selecting New > DWORD (32-bit) value, and then assign “DisableAbsoluteVolume” as its name. Step_4: Once done, double click on the “DisableAbsoluteVolume” DWORD and set its value from 0 to 1. Step_5: Now exit the Registry Editor and restart your computer. On the other hand, you can also disable or enable the Absolute Volume feature by executing a command in the Command Prompt.
  • If you want to disable the Absolute Volume feature, just execute this command: reg add HKLMSYSTEMControlSet001ControlBluetoothAudioAVRCPCT /v DisableAbsoluteVolume /t REG_DWORD /d 1 /f
  • If you want to enable the Absolute Volume feature, just execute this command: reg add HKLMSYSTEMControlSet001ControlBluetoothAudioAVRCPCT /v DisableAbsoluteVolume /t REG_DWORD /d 0 /f
After you execute the command, just restart your computer.

After your computer restarts.

Once you’re done executing the given instructions above, you have to right-click on the speaker icon located in the system tray and select Open Sound Settings and click on Manage device settings – the same controls will be visible to you like earlier. Now when you change the volume level for one speaker, the other speaker should now remain as it is and won’t change alongside the speaker.
