DCShadow is a feature in the open-source tool mimikatz. In another blog post, we cover without detection once they’ve obtained admin credentials. But DCShadow can also enable an attacker to elevate their privileges. How can a Domain Admin elevate their access even higher? By obtaining admin rights in other forests. Leveraging SID History, an attacker can add administrative SIDs to their user account and obtain admin level rights in other trusted domains and forests.
The overpass-the-hash attack is a combination of two other attacks: pass-the-hash and pass-the-ticket. All three techniques fall under the Mitre category “Exploitation of remote services.” In an overpass-the-hash attack, an adversary leverages the NTLM hash of a user account to obtain a Kerberos ticket that can be used to access network resources.
This summer, we launched Investigator, Corelight’s SaaS-based network detection and response (NDR) solution that fuses rich network evidence with machine learning and other security analytics to unlock powerful threat hunting capabilities and accelerate analyst workflows.

Do a quick search for the top cybersecurity breaches thus far in 2022 and you’ll quickly be overwhelmed with reports of cryptocurrency thefts, attacks targeting multinational corporations and critical infrastructure, and nation-state backed attacks spurred by ongoing geopolitical conflict. It’s easy for individuals to let their guard down and think they’re safe because these complex attacks aren’t targeting them specifically.

It’s essential for business recovery and continuity as advanced and unknown cyber threats continue to gain ground. Most companies don’t yet have an incident response plan. Only 19% of UK businesses have a formalized response plan, while just 46% of US businesses have a specific response plan for at least one major type of cyberattack.
Snyk Security Researchers have been using dynamic analysis techniques to unravel the behaviors of obfuscated malicious packages. A recent interesting finding in the Python Package Index (PyPi) attempted to imitate a known open source developer through identity spoofing. Upon further analysis, the team uncovered that the package, raw-tool, was attempting to hide malicious behavior using base64 encoding, reaching out to malicious servers, and executing obfuscated code.
