You have to respect that ransomware attacks let you know you’ve been attacked. You’ll have an opportunity to defend yourself and batten down the hatches.
However, a rising tide of cyberattacks is much more sneaky about things.
Called “stealth hacking,” these subtle attacks try to see your data and processes without alerting anyone that this is occurring. In the world of consumer computing, this may manifest as keystroke-monitoring malware that installs from a malicious download. The hacker hopes to remain undiscovered and gather as much data as possible until the jig is up, or perhaps never be discovered at all.
