#BlueKeep attacks go live, but it isn’t as dangerous as feared Hackers have already started using BlueKeep exploit to break into Windows systems, but according to security researchers, the exploit is not as dangerous as everybody feared. For those unaware, BlueKeep affects the Remote Desktop Protocole service(RDP), which is widely used for remote control administration. May 14 is when it first came into existence and security experts at various firms labeled it as “wormable,” meaning that code exploiting this vulnerability can be self-propagating in nature, and, therefore, can spread very quickly, just like how Wannacry spread. https://mspoweruser.com/bluekeep-attacks-go-live-but-it-isnt-as-dangerous-as-feared/amp/

#BlueKeep Attacks Have Arrived, Are Initially Underwhelming The first attacks that exploit the zero-day #Windows vulnerability install cryptominers and scan for targets rather than a worm with WannaCry potential. The wave of BlueKeep attacks that security experts predicted could take down systems globally have arrived, but they are not in showing the form nor the destructive impact experts initially feared. https://threatpost.com/bluekeep-attacks-have-arrived-are-initially-underwhelming/149829/
