In our industry, it is sometimes even difficult to predict what will happen in the next 30 seconds - let alone twelve months.

New ransomware tactic: partial encryption

There is a new trend in ransomware: In order to be faster and avoid detection, attackers rely on partial (intermittent) encryption of the files.
