  • Locking a company out of their systems isn’t the most lucrative part of ransomware anymore. Data exfiltration and threatening to release the data to the highest bidder is now the norm.

    Ransomware also typically sits on a system doing nothing for ~6 weeks before ever starting to encrypt and upload data. Even if companies have backups to restore from, they need to choose whether they’re going to restore entire machines quickly and risk still having the ransomware on the restored machine. Or they can take the long a painful route of spinning up new machines, then restoring just the data itself to individual apps/services to ensure you don’t still have ransomware after the restore.












  • This is specifically an issue with corporate M365 accounts when a user tries to migrate to a new phone without access to the old phone where the authenticator was setup.

    Personal MS accounts can backup their auth secret keys to cloud storage, and when signing in on a new device, it authenticates you with your cloud storage (Google/Apple) and properly restores your MS Authenticator app.

    The issue is that while MS says you can backup your corporate M365 accounts in MS Authenticator, it doesnt actually store the secret key, so it’s useless.

    Have your administrator enable TAP (Temporary Access Passwords) on the tenant. Then an M365 admin can create a TAP for your account that lets you login without a password/2FA. You can use the TAP to login and rejoin MS Authenticator app. The TAP expires in 1 hour by default.


  • The Oracle Cloud VPS only has SSH key authentication enabled by default. You can also set it to only allow SSH from your home IP in the virtual firewall before the machine is ever spun up.

    Their current free ARM offering is 1 machine with 4-cores and 24gb RAM for life. You can also add another 2 AMD machines with 1-core and 1gb RAM and still be in their free-tier.

    If you’re going to set it up and take advantage of the ARM machine, make sure you pick a home location for your account that has multiple availability zones. San Fran right now only has 1 zone, so if the shared ARM instances are all used up, you’ll have to wait a few days and try again. Phoenix I think has 3, so you can try with another zone right away.
