"A hijacked journal is a legitimate academic journal for which a bogus website has been created by a malicious third party for the purpose of fraudulently offering academics the opportunity to rapidly publish their research for a fee." Butler, D. (2013). Sham journals scam authors. Nature 495, 421-422.

Note that there is no one list of predatory journals. A recent article in Nature, noted that there were some journals deemed legitimate on one list that were considered predatory on another. Image source: Public Domain Vectors.
Another category of predatory publishing to be aware of is bootlegging journals. Here, journals mimic long-standing respectable journals, and republish "copies of papers from legitimate sources, under new DOIs, without crediting the original journal, and sometimes not the original author." Siler, Kyle, et. al. Predatory Publishers' Latest Scam: Bootlegged and Republished Papers. Nature, 26 October 2021.
