Itâs quite common to hear about bank webpages being modified by malware and certain resources (e.g., antivirus-related ones) being at risk of becoming blocked. How difficult is it for cybercriminals to perform such maneuvers? Letâs take a look.
So, if we visit a website, some programs are downloaded onto our computer (as text scripts with very simple syntax), and a cybercriminal can modify those programs as they see fit.
Unfortunately, no solution exists that can help determine whether what we see displayed on website pages is exactly what the site owner wants us to see. Alas, a website can be modified on the developer side (as a result of hacking, the presence of a vulnerability in the website’s engine, or due to a trivial leak of the passwords used to access it), as well as on the user side. Banking Trojans and phishers especially like to modify website pages. To minimise the risk, it is essential that you use anti-virus software that doesn’t allow malware to penetrate your computer.
Dr.Web ShellGuard technology is an effective security tool for preventing website pages from being modified. It tracks attempts made to embed malicious code (exploits) in a browser’s running process and prevents malware or phishing modifications.
