    What does this mean for security?  

    Organizations are scrambling to get newly home-bound employees up and running.  

    We’ve got anxious employees working from vulnerable home networks, and many organizations don’t have as much visibility into their remote connections and data as they’ll need. With the expanded attack surface, responding to incidents isn’t getting any easier.  

    Corporate laptops are in short supply, so organizations are making do with home systems. That’s like fighting in the dark – older or unpatched operating systems and browsers that may not be compatible with endpoint solutions.  

    We’re already seeing malicious COVID-19 links sent via email or social that lead to ransomware or browser-only attacks that threaten 365 environments. Here’s an example of a phishing attack that came in this week: 

    It’s poorly worded, but still very effective. User clicks; account or browser hijacked.
