For the past five years, a gang of hackers known as Carbanak has been targeting banks around the world, stealing well over $1 billion in total. Now, thanks to a coordinated international investigation, the as-yet-unnamed leader of the gang has been caught in Spain. The hackers spread malware by duping bank employees with „spear phishing“ emails containing malicious attachments. It instructed ATMs to spew out money at pre-determined times, prompted the transfer of money into the gang’s accounts, and modified bank databases to inflate the balances of certain accounts. Over 100 banks in 40 states were affected.
