Four men appeared in court over an alleged attempt to take control of computers at a Santander bank branch to steal millions of pounds.
It is claimed one of the plotters posed as an engineer in an attempt to fit a computer in a London branch of Santander with a "keyboard video mouse" device that allowed them to transmit its desktop contents.
The cyber gang is alleged to have tried to use the gadget to take control of all the computers at the branch in Surrey Quays shopping centre in south-east London, but the attempt failed and the Spanish bank said they were unable to steal any money.
Lanre Mullins-Abudu, 25, Dean Outram, 34, Akash Vaghela, 27 and Asad Ali Qureshi, 35 spoke only to confirm their names and details when they appeared at Westminister Magistrates' Court charged with conspiracy to steal.
Mullins-Abudu, Outram and Quereshi were remanded in custody by District Judge Howard Riddle while Vaghela was granted conditional bail.
All four are due to appear at Southwark Crown Court on September 27.
