There is a history of ads being injected with malicious code before being presented to the visitor and every so often articles are released about this issue. Phishing browser pop-ups are presented in different ways including those:
- Stating your device may have been infected by malware and to call a number for assistance. This attack often claims to be coming from Microsoft which it is not!
- Stating there has been a problem with your computer and to call a number for assistance. The number typically claims to be tech support.
- With a warning message and an accompanying audio message. The audio typically loops for dramatic effect and follows the script of the pop-up.
