Detecting and preventing malicious activity such as botnet attacks is a critical area of focus for threat intel analysts, security operators, and threat hunters. Taking up the Mozi botnet as a case study, this blog post demonstrates how to use open source tools, analytical processes, and the Elastic Stack to perform analysis and enrichment of collected data irrespective of the campaign.

SeriousSAM or CVE-2021-36934 is a Privilege Escalation Vulnerability, which allows overly permissive Access Control Lists (ACLs) that provide low privileged users read access to privileged system files including the Security Accounts Manager (SAM) database. The SAM database stores users' encrypted passwords in a Windows system. According to the Microsoft advisory, this issue affects Windows 10 1809 and above as well as certain versions of Server 2019.

Five worthy reads is a regular column on five noteworthy items we’ve discovered while researching trending and timeless topics. This week, we explore why organizations should implement Zero Trust in 2021. In 2010, John Kindervag introduced the concept of “Zero Trust” which has become a touchstone for cyber resilience and persistent security. Zero Trust is not a security product, architecture, or technology.

Continuing to ride the waves of Summer of Security and the launch of Splunk Security Cloud, Splunk Security Essentials is now part of the Splunk security portfolio and fully supported with an active Splunk Cloud or Splunk Enterprise license. No matter how you choose to deploy Splunk, you can apply prescriptive guidance and deploy pre-built detections from Splunk Security Essentials to Splunk Enterprise, Splunk Cloud Platform, Splunk SIEM and Splunk SOAR solutions.

I’m a security analyst at Orange Business Services in Paris, and one of my current projects for the Orange Group is implementing a new SIEM based on the Elastic Stack. In this blog post, I’ll share why we chose Elastic and how we were able to integrate Elastic into our existing SIEM, resulting in faster investigations and saving our engineers’ time. So follow along.

Today’s enterprise networks are heterogeneous, have multiple entry points, integrate with cloud-based applications, offer data center delivered services, include applications that run at the edge of the network, and generate massive amounts of transactional data. In effect, enterprise networks have become larger, more complex, and more difficult to secure and manage.

Multi-factor authentication (MFA) is an increasingly popular method for securing user accounts that requires users to provide two or more pieces of identifying information when logging into an application. This information can consist of unique verification links or codes sent to the user’s phone or email address, as well as time-based one-time passwords (TOTPs) generated by authenticator applications or hardware.

At the start of the pandemic, IT organizations had to undergo radical changes to support remote work. Given the urgency to shift to remote operations, IT admins opted for band-aid solutions to retain business continuity and stay connected to the core of their networks from remote locations. But now, many organizations are moving toward hybrid workforce options with employees choosing to work from both their home and office locations.

What can I say further about Ivanti’s mobile threat defense (MTD) solution for iOS, iPadOS and Android devices that has not already been mentioned in any of my previous blogs and quick video demos? If I was to state where Ivanti has a clear advantage over other unified endpoint management competitors, it is with Ivanti’s MTD solution.

We recently started using GitHub Security Advisories as part of our workflow for pushing out security releases. This post will give a brief introduction on how they work, how we use them, some of their limitations, and how we overcome them. We are still experimenting with this workflow, but the information could still be helpful for some while others might have suggestions how we could do things better.
