How Does .rose Virus Infiltrate the System?

The A1Lock ransomware, also known as the .rose virus is distributed using different strategies. The hackers may opt to use email spam messages, one of the most widely used techniques for spreading malware. In most cases social engineering tricks are utilized that attempt to make the targets infect themselves with the virus.

They can contain dangerous hyperlinks or directly serve the malware as file attachments. Usually the body contents features images and text that pose as being sent by a legitimate company or government organization.

Other methods include infected documents and installers. Many office files (spreadsheets, rich text documents or databases) can include scripts (macros) that can deliver the .rose virus.

Web scripts, ads and browser hijackers are another widely used medium responsible for virus infections. The hacker-controlled browser extensions modify essential settings of the most web browsers to redirect the victims to a hacker-controlled site.
