Graham Cluley explains:
A new cloud-based keylogger malware family is slowly but surely gaining momentum among criminals on underground web marketplaces.
The malware, dubbed "NexusLogger", appears to have first arrived on the keylogging scene at the beginning of 2017. The timing of its debut means NexusLogger's authors likely created their software over the New Year period. No wonder we haven't heard much of the keylogger until now.
Researchers at Palo Alto Networks corroborate that observation:
"The total number of attacks witnessed using NexusLogger is quite low when compared with other commodity malware families. Again, this is likely due to slow adoption by criminals. The keylogging market is quite saturated with numerous malware families, and it can be difficult for new players to enter the market."
