Sleeper Agents going unnoticed at banks
Spear phishing attack... But shouldn't there be more internal controls anyway? Situation worsened by shit-canning key staff / outsourcing???
Either way its asymmetric warfare... Hackers can afford to miss many times, but only have to get lucky once. Its the reverse of classic crime. In the movie 'Heat', DeNiro (Neil) is advised to walk away from a bank heist near the end by Voight (Nate), because the cop (Pacino) can afford to miss many times (at catching DeNiro), but DeNiro only gets one shot.
'Silence' is the total opposite if you think about it. The bad guys with their spear-phishing and / or automated-hunting-scripts can afford to miss infinite times, but the banks can't afford to screw-up even once. One gullible-user / mis-configured / unpatched server / backdoor-hack = Meltdown. That's why we're seeing so many at the moment. Not good!
