Add another case to the annals of zombie law: A federal class action says Turn Inc. used secret “zombie cookies” to track online activities of Verizon electronic device users.

Filed in San Francisco, it accuses the online ad clearinghouse of “surreptitiously” monitoring users’ activities and “thwarting industry-standard consumer safeguards of privacy” by respawning cookies that the user has deleted, reports Courthouse News.

The technology at issue in the case is discussed in detail in a Pro Publica article. It centers on an assigned Verizon tracking number that, until recently, was reportedly used by Turn to identify individuals in order to put online advertising on their device screens.

The Courthouse News article doesn’t include any comment from Turn; however, the company’s chief privacy officer told Pro Publica that “it is our absolute desire to honor people’s choices.”

Lieff Cabraser Heimann & Bernstein is representing the plaintiffs in the case.
