Mass exploitation of Atlassian Confluence CVE-2021-26084 is ongoing and expected to accelerate. Please patch immediately if you haven’t already— this cannot wait until after the weekend.
 
Holy Typo, thanks for the quick call-outs! Here's the corrected #CodebreakerTechTip: CIDR notation indicates how many bits of an IP address are part of the network prefix. For instance, 192.168.25.0/24 represents a network with 254 hosts. Ready for more? Check out Task 1.
 
In reply to @FBI
@FBI and @CISAgov shared recent trends and actions to protect against #ransomware. One step organizations can take immediately is restricting remote desktop protocol access and use. For more, read the report and strengthen your defenses against this threat.
How are your networks protected and configured to avoid exploitation? Have you built in appropriate resilience if you should become a victim?
