The Zeus Sphinx banking trojan has seen a recent resurgence in the United States, sporting some modifications and using COVID-19 spam as a lure.
 
Sphinx re-emerged in December but saw a big spike in March via the use of coronavirus themes. Since April, it has been seen attacking U.S. targets with a few changed processes.
