What is FlawedAmmyy?

FlawedAmmyy is software that cyber criminals use for malicious purposes. FlawedAmmyy is a remote access trojan (RAT) used to access computers remotely and steal personal data/information. People who have systems infected with FlawedAmmyy might experience serious problems. Therefore, all users are strongly recommended to remove (uninstall) this program immediately.

FlawedAmmyy malware

FlawedAmmyy can be used to steal private files and credentials (such as logins and passwords of various accounts), take screenshots, and access the computer microphone and camera. Cyber criminals can use it to steal Facebook, email, and other accounts, and then use them for malicious purposes.

For example, they can send malicious files, tricking people into making money transfers, and so on. Cyber criminals can use stolen private files to blackmail victims by demanding ransom payments to prevent proliferating them on the internet and sharing the files with other parties.

The same might be applied to photos taken with the victim's camera, or recordings made with the microphone.

They can also take screenshots of personal documents or other important/sensitive information and use them to extort money from victims. Thus, programs such as FlawedAmmyy can lead to a number of problems relating to privacy, financial loss, and so on. If you suspect your computer is infected with this program, it should be eliminated immediately.

Examples of other remote access tools used by cyber criminals to generate revenue are Orcus, NetSupport Manager, and Rescoms. There are many cases whereby these tools are used to download and install malicious programs on the victims's computer. For example, ransomware or trojans. In any case, if used by cyber criminals, RATs can cause serious damage.

How did FlawedAmmyy infiltrate my computer?

To trick people into installing FlawedAmmyy, cyber criminals often use spam campaigns. They send emails that contain an attached .xls (Excel) file. If executed, this file runs macro commands that execute the msiexec.exe tool (a process which is part of the Windows Operating System).

This tool downloads an MSI archive that includes a hidden executable - this decrypts and executes another executable (wsus.exe), which installs the FlawedAmmyy RAT. Other ways to proliferate malware are trojans, untrustworthy software download sources, fake software updaters and unofficial activation tools.

Trojans install other malware only if they are already installed on the system. In summary, these programs often cause chain infections. Dubious file or software download channels include Peer-to-Peer networks (eMule, torrent clients, and so on), freeware download websites, free file hosting pages, unofficial websites, third party downloaders, and other similar sources.

Cyber criminals use them to disguise malicious files (executables) as regular files. People who download and open files through dubious download channels risk installation of malware.

Fake software updaters exploit bugs/flaws of installed, outdated software, or download and install malicious programs rather than updates and fixes. Unofficial activation tools are used to activate paid software free of charge, however, they often download and install malware.

How to avoid installation of malware?

Do not open attachments or web links that are presented in irrelevant emails and sent from unknown, suspicious addresses. Keep installed software up-to-date, however, do not use unofficial tools. The best way to update is via tools/functions provided by official software developers.

Download software and files from official, trustworthy websites and use direct download links. Avoid using third party software downloaders, unofficial, suspicious websites, or other similar channels. Activate software properly, and be aware that 'cracking' and use of other unofficial tools can be dangerous (they are used to proliferate malware) and illegal.

Have a trustworthy (reputable) anti-spyware or anti-virus software installed and keep it up-to-date. 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.

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 Combo Cleaner Antivirus for Windows.
