The latest ploy cybercrooks are using to spread ransomware and other types of computer malware to provide them with remote access to PCs and Macs or to steal log-in credentials: After buying domain names with a missing or misplaced letter in website addresses belonging to well-known companies, they simply wait for you to make a typo.
The biggest threat results in the most common typos — either a misplaced or missing “c” (such as typing amazonc.om or amazon.om) so a web address ends with “.om” instead of “.com,”
It will still direct you to Amazon’s website but they will have your information.
There are at least 300 of these.
