"Philippine Overseas Employment Administration" email virus removal guide

What is the fake "Philippine Overseas Employment Administration" email?

"Philippine Overseas Employment Administration" refers to an email spam campaign, disguised as mail from Philippine Overseas Employment Administration (POEA). The term "spam campaign" defines a large scale operation, during which thousands of deceptive emails are sent. The letters of this spam campaign claim that recipients risk losing their licenses, if they do not fill out and submit the attached documents. However, these emails are fake and in no way associated with the genuine POEA. The files attached to the scam emails are designed to infect systems with NanoCore RAT (Remote Access Trojan).

Philippine Overseas Employment Administration malware-spreading email spam campaign

Philippine Overseas Employment Administration (POEA) is legitimate agency, dealing in opening benefits of the Philippine overseas employment program - and the scam emails are disguised as reminders from this governmental agency. The fake letters state that in compliance with the "POEA Advisory NO. 62- 2020 Series on accreditation of agencies" - accredited recruitment agencies must fill out the attached document and submit it to the POEA. This is supposedly a mandatory agency revalidation, which has to be carried until the listed date. Recipients are warned that all agencies that fail to comply will be suspended and have their licenses revoked. To further the impression of urgency and severity of this false warning, the emails have a file titled "POEA LIST OF DELISTED AGENCIES IN 2020.uue" attached to them. Upon opening the other attachment (which is allegedly the document recipients must fill out and send), it initiates the infection process (download/installation) of NanoCore. This piece of malicious software is classified as a Remote Access Trojan (RAT). This type of malware enables remote access and control over an infected machine. RATs can have a broad range of functionalities, which can be used to manipulate a compromised device in various ways and that can lead to especially severe issues. To summarize, trusting the fake "Philippine Overseas Employment Administration" emails can result in system infections, device and/or data damage, financial losses, serious privacy issues and identity theft. If it is suspected/known that NanoCore RAT (or other malware) has already infected the system - an anti-virus must be used to eliminate it immediately.

"You must go to the law court", "Inland Revenue Exchange System" and "Agenzia entrate" are a few examples of other malware-proliferating spam campaigns. This is a common method of spreading malicious programs (e.g. trojans, ransomware, cryptominers, etc.) and a variety of scam models are used to trick recipients into unwittingly infecting their devices. Scam emails are usually disguised as "official", "important", "urgent", "priority" and similar; they can also be presented as mail from genuine agencies, organizations, companies and other entities. However, deceptive letters can have other purposes, e.g. phishing and other scams. While such mail uses different deceptions, its end-goal is the same - to generate revenue to the scammers / cyber criminals behind it.

How did "Philippine Overseas Employment Administration Email Virus" infect my computer?

Spam campaigns infect systems through virulent files. These files can be attached to the deceptive emails or alternatively, the letters can contain download links of malicious content. Infectious files can be in various formats, e.g. executables (.exe, .run, etc.), archives (RAR, ZIP, etc.), PDF and Microsoft Office documents, JavaScript, etc. When they are opened - the infection process/chain is jumpstarted. In other words, upon being opened - these files begin downloading/installing malware. For example, Microsoft Office documents infect systems by executing malicious macro commands. Once an MS document is opened, users are asked to enable macros (i.e. to enable editing/content) - which triggers the infection. However, in Microsoft Office versions released before 2010 - malware download/installation starts the moment an infectious document is opened, as macro commands are executed automatically.

How to avoid installation of malware?

It is strongly advised against opening dubious and/or irrelevant emails, especially ones received from suspect/unknown senders. Any attachments or links found in suspicious letters must never be opened - as that can lead to a serious system infection. Additionally, it is recommended to use Microsoft Office versions released after 2010. The newer versions have the "Protected View" mode, which prevents macros from being executed upon a document's opening. Aside from spam campaigns, malicious software is also proliferated via untrustworthy download channels (e.g. unofficial and free file-hosting websites, Peer-to-Peer sharing networks and other third party downloaders), illegal activation ("cracking") tools and illegitimate updaters. Therefore, it is important to only use official/verified download sources, as well as always activate/update programs with tools/functions provided by legitimate developers. To ensure device and user safety, it is paramount to have a reputable anti-virus installed and kept up-to-date. Furthermore, it has to be used to run regular system scans and to remove detected/potential threats. If you've already opened "Philippine Overseas Employment Administration Email Virus" attachment, we recommend running a scan with Malwarebytes for Windows to automatically eliminate infiltrated malware.

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.
