Retadup is a worm that has a single purpose, which is to infect a victim’s system with other malicious programs. It is not a new threat since its first versions were discovered in 2017. The hackers behind the malware continued to upgrade it and used it to spread various infections up till 2019 when cybersecurity experts teamed up and managed to deactivate the worm. If you want to know what kind of malicious applications it used to spread before its deactivation and other details about this threat, we encourage you to read our full report. At the end of this article, you can find a step by step removal guide showing how to delete Retadup manually. Of course, it might be safer and easier to erase such a threat with a reputable antimalware tool that would also help eliminate other possible infections that could have been dropped by this worm.
Retadup was most likely spread with files disguised to look harmless. As a result, the threat ended up on computers used by those who carelessly open files obtained from the Internet. If you do not want to make a mistake of getting tricked into opening malicious files, you should never launch data received from untrustworthy file-sharing websites, Spam emails, obtained via unreliable advertising content, and so on. Never forget that files, which look like text documents, pictures, or other data that you would not consider to be malicious, can be infected. What’s more, the research revealed that systems affected by this worm were not protected by antimalware tools. It would be a good idea not only to install a reputable antimalware tool, but also to use it to scan files that you do not know to be harmless for sure. That is if it is important for you to keep your device clean and secure.
The malicious application used to drop a text document and an executable file right after a victim would launch its installer. Both the document and executable had names from 21 random characters, so the titles of such data could vary from victim to victim. After getting installed, Retadup operated on a system without revealing its presence. The hackers behind this malicious application used it to drop malware they wanted to infect a victim’s computer with. It is said that Retadup carried Stop Ransomware, Monero miners, and password stealer called Arkei. The ransomware encrypted victims' files and displayed a message demanding to pay a ransom if a victim wanted his data back. The Monero miners used a victim’s computer resources to mine this particular cryptocurrency, which could have caused lag and faster device’s wear. As for the password-stealing application, it could have stolen various passcodes that might have been misused for purposes like scamming victims, taking control over their accounts, selling such data on the dark web, and so on.
Needless to say, that both the worm and the malicious applications installed by it should be erased as fast as possible to prevent more damage.
