Vision: What the hack is going on? A first look at how website owners became aware that their website was hacked

Websites are an essential part of today's business activities. Content Management Systems (CMS) are known for the fact that even laypersons can create good-looking websites with simple means and without huge costs. But if websites are not maintained regularly, they are prone to vulnerabilities. Such vulnerabilities can be abused, e.g., for third party redirects. Informing website owner about this type of attack is challenging. To gain more information about how website owners are informed about vulnerabilities on their websites, we invited 156 website owners to participate in an online survey. We asked those who had fixed the third party redirect before we could inform them, how they became aware of the attack. The participants could choose to answer the questionnaire via a link to an online platform, or to send their answers back to us via e-mail. Only 11 people answered our questionnaire, and only four people were already aware of the attack before our invitation e-mail. Based on these four answers, we assumed that we can confirm previous research with respect to the design of a vulnerability notification. Nevertheless, it would be interesting to see if -- with a bigger sample -- we can also confirm our findings that a) online surveys, even if they can only be accessed by clicking an unknown link, are preferred over responding via e-mail, b) the number of responses can be increased by sending out several reminder, and c) a sender attributed with higher authority increases the response rate. ... mehrFurthermore, we suggest that future research on vulnerability notifications examines whether recipients distinguish between credibility and trustworthiness of notifications when remediating attacks.
