Phishing is one of the most common forms of social engineering attacks and is regularly used by criminals to compromise millions of accounts every year. Numerous solutions have been proposed to detect or prevent identity thefts, but phishers have responded by improving their methods and adopting more sophisticated techniques. One of the most recent advancements is the use of browser fingerprinting. In particular, fingerprinting techniques can be used as an additional piece of information that complements the stolen credentials This is confirmed by the fact that credentials with fingerprint data are sold for higher prices in underground markets. To understand the real extent of this phenomenon, we conducted the largest study of the phishing ecosystem in the topic by analyzing more than 1.7M recent phishing pages that emerged over the course of 21 months. In our systematic study, we performed detailed measurements to estimate the prevalence of fingerprinting techniques in phishing pages. We found that more than one in four phishing pages adopt some form of fingerprinting. This seems an ever growing trend as the percentage of pages using these techniques steadily increased during the analysis period (last month doubling what detected in the first month).
