"iPhone 12 email virus" removal guide

What is "iPhone 12 email virus"?

"iPhone 12 email virus" refers to a malware-spreading email spam campaign. The term "spam campaign" is used to define a mass-scale operation, during which thousands of scam emails are sent. The deceptive letters distributed through this spam campaign concern a fake order of an iPhone 12, which has been paid for and can still be canceled within 24 hours. It must be emphasized that all of the information given by these emails is false; hence, no unauthorized order has been made with the recipients' credit card nor does it have to be cancelled. Said letters are used to trick recipients into opening the attached file (the supposed order invoice), which will begin the infection process of DUNIHI malware. This piece of malicious software is capable of receiving and executing commands on a system; thereby, allowing the cyber criminals using it - a certain level of control over the compromised machine.

iPhone 12 malware-spreading email spam campaign

The scam letters distributed via "iPhone 12 email virus" spam campaign (subject/title "Thank you for your Order No.476702"; may vary) thank recipients for the order and inform them that it will be shipped tomorrow. The emails then state that the order has been paid for with a credit card. The ordered product is allegedly an iPhone 12 Pro 256 GB and its price is listed as - 1386,86 USD. Furthermore, recipients are informed that the order can be cancelled through the attached Excel spreadsheet file. To further increase the impression of urgency, the letters state that the fake order cannot be cancelled after 24 hours. However, should the attached document be opened (whether to cancel the bogus purchase or to investigate it) - the download/installation of DUNIHI malware will be initiated. As mentioned in the introduction, this malicious program can receive and execute commands on an infected system. Some of its primary functionalities include - file extraction (download), infiltration (upload), execution and deletion. Its ability to upload and execute files allows DUNIHI to be used to cause chain infections, i.e. download/install additional malware (e.g. ransomware, cryptominers, etc.). In addition, this malicious software is capable of infecting and proliferating via storage devices (e.g. external hard drives, USB Flash drives, etc.). Therefore, a storage device that has been connected to an infected system - could infect a different machine when plugged into it. To summarize, by trusting "iPhone 12 email virus" users can experience system infections, severe privacy issues, financial losses and even identity theft. If it is known/suspected that DUNIHI (or other malware) has already infected the system - an anti-virus must be used to eliminate it without delay.

"VodaFone Email Virus", "Inditron Enterprises Email Virus", "$100 Amazon Gift Card Email Virus" and "CDP Email Virus" are some examples of other malware-proliferating spam campaigns. Scam emails can have a wide variety of disguises/thematics; they may be presented as "urgent", "priority", "important" and/or as mail from legitimate institutions, organizations, companies and other entities. However, spam campaigns are not used exclusively to spread malicious programs. Deceptive letters are also used for phishing and other scams. Due to the relative prevalence of spam mail, it is strongly recommended to exercise caution with incoming emails.

How did "iPhone 12 email virus" infect my computer?

Systems are infected via malicious files distributed through spam campaigns. These files can be attached and/or linked inside the emails. Infectious files can be in various formats (e.g. Microsoft Office and PDF documents, archive and executable files, JavaScript, etc.). When these files are executed, run or otherwise opened - the infection process (i.e. malware download/installation) is triggered. For example, Microsoft Office documents (e.g. "Invoice_24077.xlsb") cause infections by executing malicious macro commands. In Microsoft Office versions released prior to 2010 - malware download/installation begins the moment an infectious document is opened. However, newer versions have "Protected View" mode that prevents automatic execution of macros. Instead users are asked to enable macro commands (i.e. to enable editing/content); hence, infection processes can only be jumpstarted by manually enabling macros.

How to avoid installation of malware?

Suspicious and/or irrelevant emails must not be opened, especially any attachments or links found in them - as they are sources of potential system infections. Additionally, it is recommended to use Microsoft Office versions released after 2010. However, malware is also commonly distributed via untrustworthy download channels (e.g. unofficial and free file-hosting websites, Peer-to-Peer sharing networks and other third party downloaders), illegal activation tools ("cracks") and fake updaters. Therefore, it is advised to always download from official/verified sources, as well as activate and update with tools/functions provided by genuine developers. To protect device and user safety, it is crucial to have a dependable anti-virus/anti-spyware suite installed and kept updated. This software has to be used to run regular system scans and to remove detected threats. If you've already opened "iPhone 12 Email Virus" attachment, we recommend running a scan with Malwarebytes for Windows to automatically eliminate infiltrated malware.

To remove this malware we recommend using Malwarebytes for Windows. If you wish to remove malware manually, the first step is to identify the name of the malware that you are trying to remove. Here is an example of a suspicious program running on a user's computer:

manual malware removal step 5Check the list provided by the Autoruns application and locate the malware file that you want to eliminate.

You should write down its full path and name. Note that some malware hides process names under legitimate Windows process names. At this stage, it is very important to avoid removing system files. After you locate the suspicious program you wish to remove, right click your mouse over its name and choose "Delete".

locate the malware file you want to remove

After removing the malware through the Autoruns application (this ensures that the malware will not run automatically on the next system startup), you should search for the malware name on your computer. Be sure to enable hidden files and folders before proceeding. If you find the filename of the malware, be sure to remove it.

searching for malware file on your computer

Reboot your computer in normal mode. Following these steps should remove any malware from your computer. Note that manual threat removal requires advanced computer skills. If you do not have these skills, leave malware removal to antivirus and anti-malware programs. These steps might not work with advanced malware infections. As always it is best to prevent infection than try to remove malware later. To keep your computer safe, install the latest operating system updates and use antivirus software.

To be sure your computer is free of malware infections, we recommend scanning it with Malwarebytes for Windows.
