Nope, nothing new.
And anything out there that’s “old” are thing that you’d have to download and run. Nothing that could catch you by surprise, in other words.
Here’s 4 steps to take:
1) Download wisely. Don’t run mystery programs from untrusted sites.
2) Turn on your Firewall in System Preferences
3) Find the advanced section of the firewall that enables “Stealth Mode” and turn it on
4) Go into Safari preferences and turn OFF the feature that runs downloaded programs automatically
That’s pretty much it. You should be perfecly fine if you follow those 4 rules.
