The antivirus development company Bitdefender has detected this new attempt to obtain the personal data of hundreds of users, and has shared its analysis in a study. Bitdefender notes that millions of people have potentially been affected, judging by the followers of the fake pages on Facebook. These pages impersonate legitimate artificial intelligence companies or services such as Midjourney, DALL-E 3, Evoto or ChatGPT 5.

It was blocked on March 8, but not before having run massive ad campaigns since at least June 2023.
