📚 Must-Reads
“Offensively Groovy” focuses on leveraging Groovy scripting for post-exploitation tasks on Jenkins servers, showcasing techniques like file access, network enumeration, and credential extraction. With Java Native Access (JNA), it enables interaction with Windows APIs, supporting actions such as process enumeration and executing code. Examples include methods for data exfiltration and system interaction, presenting Groovy as a versatile tool in red team operations, particularly for automating security tasks within Jenkins environments.

Sentinelone discusses a new macOS ransomware, NotLockBit, which mimics the LockBit ransomware group but originates from a different threat actor. It targets Intel Macs, exploiting AWS S3 for data exfiltration, and uses asymmetric encryption, making decryption difficult without the private key. SentinelOne identified multiple samples that reveal the malware’s evolution in obfuscation, feature updates, and anti-detection techniques, hinting at an active threat actor refining their approach to target macOS users.

Red Canary’s October 2024 Intelligence Insights focuses on prevalent threats, including ChromeLoader, SocGholish, and LummaC2, which remain high-risk malware affecting user environments. Notably, the report discusses “paste and run,” a technique where attackers trick users into executing malicious PowerShell scripts by pasting them into the Windows Run dialog. Additionally, payloads such as information stealers are analyzed, with tips for detection, especially through monitoring specific PowerShell commands and network connections. For a deeper dive into these findings, view the full post here.
Morphisec’s blog highlights the rise of in-memory runtime attacks, explaining how traditional cybersecurity tools often fail to detect them due to their fileless nature and ability to evade scanning. These attacks, involving threats like Cobalt Strike and RATs, exploit application memory, remaining invisible to signature-based solutions. Morphisec suggests using adaptive defenses like Automated Moving Target Defense (AMTD) to prevent in-memory compromises, effectively blocking advanced threats without performance loss.

The Microsoft blog examines the rising threat of ransomware attacks on U.S. healthcare systems, spotlighting incidents where attacks led to severe operational disruptions and patient risks. The report covers ransomware’s financial toll on healthcare, the sector’s unique vulnerabilities, and tactics attackers use, like exploiting outdated systems. Strategies for resilience include fostering security governance, implementing layered defenses, and reinforcing response plans through regional cooperation and staff training.
