O2 Bill Email Virus
Written by Tomas Meskauskas on (updated)
What is "O2 bill Email Virus"?
Cyber criminals proliferate the "O2 bill Email Virus" scam by sending emails to many people. This method is known as a spam campaign.
The main objective of this scam is to infect computers with the Emotet, high-risk malicious program, which can cause privacy issues and infect computers with additional programs of this type. Do not trust these emails or open attachments presented within them.
This email is presented as a message from O2 (a telecommunications service provider) regarding a monthly bill. It contains a link ("Go to my bill >") that, once clicked, opens a PDF file, which is identical to the received email message - it contains identical text and a website link, however, in this instance, the presented link opens a Microsoft Word document.
If opened with MS Office 2010 or later (with Protected View mode), the software should warn users that documents downloaded from the internet can contain viruses. By clicking "Enable editing" and then "Enable content" buttons people allow this malicious document to download and install the aforementioned Emotet computer infection.
Cyber criminals use this program to steal sensitive, personal information such as logins and passwords, details relating to browsing activity, and so on. The gathered data might contain banking information that the program can use to cause financial loss.
Furthermore, this program also operates as a Trojan - it proliferates other infections, thus causing chain infections. Therefore, ignore the "O2 bill Email Virus" scam and do not open the presented link. Note that cyber criminals often use names of various well-known companies.

"O2 bill Email Virus" is a spam campaign, a scam that is very similar to many others such as "TD Bank Email Virus", "Royal Bank Of Canada Email Virus", and "Unicredit Bank Email Virus". Typically, cyber criminals use them to trick people into installing high-risk computer infections such as Adwind, Pony, FormBook, and so on.
These programs are designed to steal personal data that can be used to generate revenue for the developers and cause financial loss for the victims.
How did "O2 bill Email Virus" infect my computer?
In this case, it is not enough simply to click the link presented in this email. A link in the opened PDF file must also be clicked. Then, permission to enable macros commands (enable editing of content) must also be granted.
Once these steps are performed, a malicious document (MS Word) installs and downloads the Emotet computer infection. Generally, these emails can lead to computer infections only if the attachments presented in them are opened.
How to avoid installation of malware?
Do not download attachments or click links in emails received from unknown, suspicious addresses. These emails are often presented as official and legitimate - cyber criminals use names of popular brands/companies, however, in most cases they are irrelevant to the recipients. In these cases, they should be ignored.
Download software using official sources and avoid torrent clients, eMule, unofficial sites, third party downloaders, etc. Software cracking tools should not be used, since they often install malicious programs rather than activating any software. Furthermore, using these tools is a cyber crime.
Finally, having reputable anti-virus or anti-spyware software installed and enabled can be a very good prevention. If you have already opened "O2 bill Email Virus" attachment, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate infiltrated malware.

Types of malicious emails:
Most commonly, cybercriminals use deceptive emails to trick Internet users into giving away their sensitive private information, for example, login information for various online services, email accounts, or online banking information.
Such attacks are called phishing. In a phishing attack, cybercriminals usually send an email message with some popular service logo (for example, Microsoft, DHL, Amazon, Netflix), create urgency (wrong shipping address, expired password, etc.), and place a link which they hope their potential victims will click on.
After clicking the link presented in such email message, victims are redirected to a fake website that looks identical or extremely similar to the original one. Victims are then asked to enter their password, credit card details, or some other information that gets stolen by cybercriminals.
Emails with Malicious Attachments
Another popular attack vector is email spam with malicious attachments that infect users' computers with malware. Malicious attachments usually carry trojans that are capable of stealing passwords, banking information, and other sensitive information.
In such attacks, cybercriminals' main goal is to trick their potential victims into opening an infected email attachment. To achieve this goal, email messages usually talk about recently received invoices, faxes, or voice messages.
If a potential victim falls for the lure and opens the attachment, their computers get infected, and cybercriminals can collect a lot of sensitive information.
While it's a more complicated method to steal personal information (spam filters and antivirus programs usually detect such attempts), if successful, cybercriminals can get a much wider array of data and can collect information for a long period of time.
This is a type of phishing. In this case, users receive an email claiming that a cybercriminal could access the webcam of the potential victim and has a video recording of one's masturbation.
To get rid of the video, victims are asked to pay a ransom (usually using Bitcoin or another cryptocurrency). Nevertheless, all of these claims are false - users who receive such emails should ignore and delete them.
How to spot a malicious email?
While cyber criminals try to make their lure emails look trustworthy, here are some things that you should look for when trying to spot a phishing email:
- Check the sender's ("from") email address: Hover your mouse over the "from" address and check if it's legitimate. For example, if you received an email from Microsoft, be sure to check if the email address is @microsoft.com and not something suspicious like @m1crosoft.com, @microsfot.com, @account-security-noreply.com, etc.
- Check for generic greetings: If the greeting in the email is "Dear user", "Dear @youremail.com", "Dear valued customer", this should raise suspiciousness. Most commonly, companies call you by your name. Lack of this information could signal a phishing attempt.
- Check the links in the email: Hover your mouse over the link presented in the email, if the link that appears seems suspicious, don't click it. For example, if you received an email from Microsoft and the link in the email shows that it will go to firebasestorage.googleapis.com/v0... you shouldn't trust it. It's best not to click any links in the emails but to visit the company website that sent you the email in the first place.
- Don't blindly trust email attachments: Most commonly, legitimate companies will ask you to log in to their website and to view any documents there; if you received an email with an attachment, it's a good idea to scan it with an antivirus application. Infected email attachments are a common attack vector used by cybercriminals.

Example of a spam email:
What to do if you fell for an email scam?
- If you clicked on a link in a phishing email and entered your password - be sure to change your password as soon as possible. Usually, cybercriminals collect stolen credentials and then sell them to other groups that use them for malicious purposes. If you change your password in a timely manner, there's a chance that criminals won't have enough time to do any damage.
- If you entered your credit card information - contact your bank as soon as possible and explain the situation. There's a good chance that you will need to cancel your compromised credit card and get a new one.
- If you see any signs of identity theft - you should immediately contact the Federal Trade Commission. This institution will collect information about your situation and create a personal recovery plan.
- If you opened a malicious attachment - your computer is probably infected, you should scan it with a reputable antivirus application. For this purpose, we recommend using Combo Cleaner Antivirus for Windows.
- Help other Internet users - report phishing emails to Anti-Phishing Working Group, FBI’s Internet Crime Complaint Center, National Fraud Information Center and U.S. Department of Justice.
