What Is the New Malware Called Gootloader?
Gootkit malware has been in existence for about 5 or more years, distributing ransomware that encrypts people’s files until they pay a ransom. This recent addition to their family, the Gootloader malware, works by using niche Google searches to infect people’s devices.
The hackers don’t go for random sites but select top sites in specific niches, including healthcare, retail, hotel, music, and other industries, because they believe those sites will rank higher in search results. This way, more visitors to the sites can get infected. The hackers also targeted sites of English, Korean, and German businesses.
What Is the Effect of the Malware on Your Website?
