PiZap Data Breach (2017)

The online photo editing platform, piZap, faced a security breach in December 2017. Later, in February 2019, this compromised data appeared for sale on a dark web marketplace alongside other datasets. This breach exposed 42 million unique email addresses, as well as names, genders, and links to Facebook profiles for those who authenticated through Facebook. Furthermore, for accounts on piZap created without Facebook's authentication, passwords stored as SHA-1 hashes were also disclosed.
