Once the packages are accepted on the marketplaces, the publishers push an update that introduces the malicious code, then inflate their download counts to make them appear legitimate and trustworthy.

Also, artificially increasing download counts can manipulate search results, with the malicious extension appearing higher in the results, often very close to the legitimate projects it impersonates.
