Proactively finding and eliminating advanced threats through threat hunting is a growing necessity for many organizations, yet few have enough resources or skilled employees to do it effectively. For those who do have an active threat hunting program, the process is often manual and time consuming. With cloud security automation, however, you can implement rules that automatically adjust your security policies based on the latest threat data.
One of the most commonly used techniques is to dump credentials after gaining initial access. Adversaries will use one of many ways, but most commonly Mimikatz is used. Whether it be with PowerShell Invoke-Mimikatz, Cobalt Strike’s Mimikatz implementation, or a custom version. All of these methods have a commonality: targeting LSASS.
In an effort to stay ahead of improvements in automated detections and preventions, adversary groups continually look to new tactics, techniques and procedures (TTPs), and new tooling to progress their mission objectives. One group — known as BlackCat/ALPHV — has taken the sophisticated approach of developing their tooling from the ground up, using newer, more secure languages like Rust and highly customized configuration options per victim.
Implementing robust defense strategies helps to mitigate the risk of cyberthreats in the early stages of an attack. Threat hunting, as part of this strategy, enables organizations to find those unknown threats that manage to bypass technology-based controls by detecting abnormal behaviors. With a number of challenges associated with executing a defense approach, how are IT leaders approaching this problem? Pulse and WatchGuard surveyed 100 IT leaders to find out.
Over recent months, the CrowdStrike Falcon OverWatch™ team has tracked an ongoing, widespread intrusion campaign leveraging bundled.msi installers to trick victims into downloading malicious payloads alongside legitimate software. These payloads and scripts were used to perform reconnaissance and ultimately download and execute NIGHT SPIDER’s Zloader trojan, as detailed in CrowdStrike Falcon X™ Premium reporting.
In November 2021, a vulnerability was discovered in a ubiquitous Linux module named Polkit. Developed by Red Hat, Polkit facilitates the communication between privileged and unprivileged processes on Linux endpoints. Due to a flaw in a component of Polkit — pkexec — a local privilege escalation vulnerability exists that, when exploited, will allow a standard user to elevate to root.
