Alert Pack: Valid Accounts (MITRE Att&ck Technique: T1078)
Purpose
Once an attacker gets access to a valid account and uses that account for their will, then your company could have significant disruptions. Proper accounts can lead to various attacks across the MITRE framework resulting in gaining Initial Access, Persistence, Privilege Escalation, and Defense Evasion. Knowing this, Devo had to create detections to help your SOC understand when valid accounts are compromised.
These detections will help lower your MTTR for these events by providing you with real-time updates from these accounts so that the appropriate action can be taken. Download them today, and improve your coverage.

What are Valid Accounts?
Adversaries may obtain and abuse credentials of existing accounts as a means of gaining Initial Access, Persistence, Privilege Escalation, or Defense Evasion. Compromised credentials may be used to bypass access controls placed on various resources on systems within the network and may even be used for persistent access to remote systems and externally available services, such as VPNs, Outlook Web Access, network devices, and remote desktop. Compromised credentials may also grant an adversary increased privilege to specific systems or access to restricted areas of the network. Adversaries may choose not to use malware or tools in conjunction with the legitimate access those credentials provide to make it harder to detect their presence
