Win32/Filecoder.Trigona.A is a type of malicious software, commonly known as ransomware. It is designed to encrypt files on a computer system, making them inaccessible to the user until a ransom is paid to the attackers. The specific details of how this ransomware infects computers can vary, but here are a few common methods:
1. Email attachments: The ransomware may be distributed through malicious email attachments. The attackers send emails pretending to be legitimate organizations or individuals, tricking the recipient into opening the attachment, which then downloads and executes the ransomware.
2. Exploit kits: Ransomware can exploit vulnerabilities in software or the operating system to gain unauthorized access to a computer. By exploiting these vulnerabilities, the malware can silently install itself on the system without the user’s knowledge.
3. Malicious websites: Visiting compromised or malicious websites can lead to the automatic download and execution of the ransomware. These websites may contain malicious scripts or exploit kits that exploit vulnerabilities in the user’s browser or plugins.
4. Infected software: Sometimes, legitimate software installers or updates can be compromised and bundled with ransomware. When users download and install these infected files, the ransomware is also installed on their systems.
Once the ransomware infects a computer, it typically starts encrypting files using a strong encryption algorithm. It may target specific file types or encrypt all files it can find on the system, including documents, photos, videos, and more. After the encryption process is complete, the ransomware displays a ransom note demanding payment in exchange for a decryption key that can restore the encrypted files.
It is important to note that paying the ransom does not guarantee that you will regain access to your files or prevent future attacks. It is recommended to take preventive measures, such as regularly backing up important files, keeping software up to date, using reputable antivirus software, and exercising caution when opening email attachments or visiting unfamiliar websites.
