SAN FRANCISCO/WASHINGTON (Reuters) - The U.S. Federal Bureau of Investigation (FBI) has struggled to stop a hyper-aggressive cybercrime gang that's been tormenting corporate America over the last two years, according to nine cybersecurity responders, digital crime experts and victims.

For more than six months, the FBI has known the identities of at least a dozen members tied to the hacking group responsible for the devastating September break-ins at casino operators MGM Resorts International and Caesars Entertainment, according to four people familiar with the investigation.
