US law enforcement officials have apprehended two suspected ZBot "mules" in Wisconsin.
The two men are linked to an international malware gang that allegedly hijacked computers around the world and stole millions of dollars from online bank accounts.
Dorin Codreanu and Lilian Adam will be transferred to NYC where they will face multiple charges of committing bank fraud.
"The men, both 21 years old, are believed by the authorities to be 'money mules,' used to transfer money from accounts, once they have been compromised through use of malware," explained senior Sophos security expert Graham Cluley.
"ZBot, also known as Zeus, is a family of malware that can hijack your computer, making it part of a criminal botnet."
To be sure, over the past few years, nefarious cybercriminals have used different versions of ZBot to steal money from online bank accounts, login details for social networking sites and email/FTP information.
