Legitimate websites can get infected with malware, which it then spreads, in a number of ways. Buggy and unpatched software, for instance, can be full of exploits and security holes, which hackers can use to their advantage. An advertiser for a site may also program in a redirect that takes you to a page that might either infect your system with malware, or ransomware. Another way in which malware might be spread to your computer is through malicious browser extensions, that seem legitimate until it’s too late.
- Today’s attackers use automated exploit kits that seek out vulnerable websites and look for one or more vulnerabilities.
- Exploit kits get routinely updated and are rated by users so that other users can judge their exploit efficiency.
- Hackers like to compromise ad networks because they can quickly distribute malicious scripting code across the internet and hit many websites at once.
