In January and February of 2021, the threat actor called Hafnium used a number of post-exploitation tools after gaining access to Exchange servers through a zero-day exploit. One of their persistence methods was creating new user accounts in the domain, giving them the ability to log back into the network using normal authentication rather than use a web shell or continue to re-exploit the vulnerability (which has since been patched).
If you haven’t been living under a rock for the past few weeks, you've probably come across the recent Microsoft Exchange Server vulnerabilities and its associated exploits.Stop!!! The first thing you should do is to go and patch any Exchange servers you may be running, then you can come back and finish reading this blog. Microsoft's blog provides links to various tools to help in this regard.
Every security team should utilize security frameworks in their strategy and tactics to help reduce risk from common cybersecurity threats. Security frameworks guide organizations on how they should develop, build, and maintain their IT security policies and procedures while sharing best practices for meeting compliance requirements. Healthcare operations in particular are often presented with increasing regulatory scrutiny and obligations that must be met in order to be competitive.
In the last 90 days, the news of cyberattacks on critical infrastructure has been stunning. From the unprecedented breach represented by Sunburst to the more recent bone-chilling attack at the Oldsmar water facility, the urgency to secure critical infrastructure in transportation, utilities, energy, water, critical manufacturing, telecommunications, healthcare, government facilities and the defense sector has never been higher.
Some tasks are better off automated. Paying bills on time? Automated payments. Orchestrating a coordinated response to security alerts and triaging security events? There’s Splunk Phantom for that. Monotonous tasks, in our work and personal lives, should and can be automated in order to free up time and energy to focus on the things that matter.
