Yes. SMBs are increasingly being targeted by ransomware gangs.
This is primarily for two reasons:
Being the perfect target: SMBs present juicier targets than individuals, they are also less secure than bigger businesses – they sit in a sweet spot.
No consequences: SMBs don’t have the power to track down or pursue hackers; even if they find out who was responsible for a ransomware attack they still won’t be able to do much about it – this encourages the attackers.
