February 24, 2023 marks one year since Russia invaded Ukraine, starting a conflict that has killed more than 8,000, injured more than 13,300, and displaced more than 14 million people in the past year, according to the UN. Physical warfare between Ukraine and Russia has been accompanied by cyberwarfare between the two countries. This blog post focuses on cyberwar, particularly what we can learn from the past year.

This new feature automates assigning severity levels to each incident, allowing security teams to quickly identify the most critical ones and prioritize their response accordingly.

Whether you realize it or not, service accounts represent a major risk to your data security. This article explains the fundamentals of service accounts and how attackers can exploit them so you can prevent yours from being compromised.

Mimikatz provides attackers with several different ways to steal credentials from memory or extract them from Active Directory. One of the most interesting options is the MemSSP command. An adversary can use this command to register a malicious Security Support Provider (SSP) on a Windows member server or domain controller (DC) — and that SSP will log all passwords in clear text for any users who log on locally to that system.

One year ago today, Russia launched a massive combined arms ground, air, and sea assault against Ukraine, including a large cyber component designed to sow confusion among Ukrainian authorities. At the first anniversary, the initial takeaway is the role played by cyber has not been as prominent as predicted for what has turned into the largest European land war since 1945. Russia and Ukraine are still actively using their cyber troops to conduct a variety of attacks against their foe.

A critical part of an organization’s overall cybersecurity strategy, Attack Surface Management (ASM) helps organizations to: This article describes ASM is, including why it is needed and how it works. At the end, I’ll discuss how software solutions can automate attack surface management. (This article was written by Shanika Wickramasinghe. See more of Shanika's contributions to Splunk Learn.)

Kroll helps development teams build agile penetration testing programs that prioritize security posture throughout the project life cycle while maintaining a rapid release cadence. When it comes to modern application delivery, speed and agility are the name of the game. Customer demands are driving rapid release cycles, pushing development teams to create new products and to update existing ones at a much more aggressive pace.

Our increasing dependence on the internet and, specifically, email for business and personal communication has produced the perfect environment for cybercriminals to launch phishing attacks. As organization’s technical controls have advanced, cybercriminals have evolved their attacks, making them more difficult for traditional email security solutions that use signature-based detection (such as Microsoft and secure email gateways (SEGs) to detect.

This and other notable threats from the previous quarter, as well as a look ahead to potential issues in 2023, are discussed in our Q4 Threat Landscape 2022 report.
