Phishers are abusing Google and Adobe open redirects to bypass spam filters and redirect users to malicious sites.
Crooks abuse Google and Adobe services to create URLs that point to malicious websites that anyway are able to bypass security filters because they appear as legitimate URLs from trusted IT giants.
“Open redirectors take you from a Google URL to another website chosen by whoever constructed the link. Some members of the security community argue that the redirectors aid phishing, because users may be inclined to trust the mouse hover tooltip on a link and then fail to examine the address bar once the navigation takes place.“ reads the post published by Google.
