malware installation

Cybercriminals are sending counterfeit email invitations that, when clicked, install a backdoor on the victim's computer, allowing hackers full control. The scam often involves downloading a file named “invites.msi,” which is a Windows Installer package. This file can install ScreenConnect, a legitimate remote support tool that can be exploited by attackers to monitor screens, access files, and deploy additional malware. Many security engines fail to flag this software as malicious, making it difficult to detect. If someone suspects they have fallen victim to this scam, they should disconnect from the internet, check for and uninstall any remote management software, run a comprehensive antivirus scan, change passwords for critical accounts, enable two-factor authentication, inform their IT department if applicable, and consider performing a full Windows reset. The scam originated from a compromised email account, which was used to send the malicious link to contacts. Implementing two-factor authentication and using a password manager can help prevent such incidents. Users should be cautious of any email invitations that require downloading and running installer files.
