Written by Tomas Meskauskas on (updated)
What is Escanor (Esca)?
Escanor, also known as Esca, is a Remote Access Trojan (RAT). Malware of this kind operates by enabling remote access and control over infected devices. RATs tend to be highly multifunctional and pose a wide range of threats. Escanor (Esca) is a cross-platform malware that targets both Windows and Android Operating Systems (OSes).
Significant Escanor (Esca) RAT activity has been noted in the Middle East, North America, Central America, and South-East Asia.
Escanor (Esca) malware overview
Escanor (Esca) is classified as a RAT (Remote Access Trojan). Malware within this classification enables remote access/control over infected machines. These trojans can perform a wide variety of actions that typically include manipulation of system/user data and installed applications.
RATs often have spyware (e.g., keylogging, recording audio/video via microphones and cameras, taking screenshots, etc.) and data-stealing capabilities (e.g., downloading files, extracting information from installed apps, etc.).
Escanor (Esca) targets both Windows and Android OSes. The latter is interesting, as in addition to more standard abilities like keystroke recording (keylogging), accessing cameras, and obtaining GPS coordinates, it specifically targets online banking applications. The Android version can intercept and use OTPs sent by banks - thus gaining access to the compromised bank account and the funds stored therein.
To summarize, Escanor (Esca) infections can result in serious privacy issues, significant financial losses, and identity theft. If you suspect that your device is already infected with the Escanor (Esca) RAT (or other malware), we strongly advise using an anti-virus to remove it without delay.

Remote access trojan examples
We have analyzed thousands of malware samples; VileRAT, Woody, Manjusaka, and ApolloRAT are merely a few of our latest finds of the RAT variety.
The threats posed by a malicious program depend on its capabilities and the cyber criminals' modus operandi. Remote access trojans typically have a broad range of functionalities - hence, they pose particularly varied threats. However, regardless of malware operates - its presence on a system endangers device integrity and user safety. Therefore, it is essential to eliminate threats immediately upon detection.
How did Escanor (Esca) infiltrate my computer?
Escanor (Esca) RAT's developers offer it for sale on the Web. Additionally, it is provided in malicious Microsoft Office and PDF documents - readied for distribution. Hence, it is most commonly delivered in these formats.
While this informs the potential formats used in Escanor (Esca) RAT's proliferation, it does not indicate the distribution method.
Typically, cyber criminals use phishing and social engineering tactics for this purpose. The most commonly used malware distribution techniques include: malicious attachments and links in spam emails/messages/SMSes, drive-by (stealthy and deceptive) downloads, dubious download channels (e.g., unofficial and freeware websites, P2P sharing networks, etc.), online scams, illegal software activation tools ("cracks"), fake updates, and malvertising.
How to avoid installation of malware?
We highly recommend researching software and downloading it from official/verified sources. Additionally, all programs must be activated and updated using functions/tools provided by legitimate developers, as illegal activation tools ("cracks") and third-party updaters may contain malware.
We also advise exercising caution with incoming mail. The attachments/links present in suspicious/irrelevant emails, SMSes, and other messages - must not be opened since that can result in a system infection.
It is paramount to have a dependable anti-virus installed and kept up-to-date. This software must be used to run regular system scans and to remove detected threats. If you believe that your computer is already infected, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate infiltrated malware.

Extract the downloaded archive and run the Autoruns.exe file.
In the Autoruns application, click "Options" at the top and uncheck "Hide Empty Locations" and "Hide Windows Entries" options. After this procedure, click the "Refresh" icon.
Check 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".
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.
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 Combo Cleaner Antivirus for Windows.
