Tricks and Treats: GHOSTPULSE’s new pixel-level deception
The updated GHOSTPULSE malware has evolved to embed malicious data directly within pixel structures, making it harder to detect and requiring new analysis and detection techniques.
Cups Overflow: When your printer spills more than Ink
Elastic Security Labs discusses detection and mitigation strategies for vulnerabilities in the CUPS printing system, which allow unauthenticated attackers to exploit the system via IPP and mDNS, resulting in remote code execution (RCE) on UNIX-based systems such as Linux, macOS, BSDs, ChromeOS, and Solaris.
Betting on Bots: Investigating Linux malware, crypto mining, and gambling API abuse
The REF6138 campaign involved cryptomining, DDoS attacks, and potential money laundering via gambling APIs, highlighting the attackers' use of evolving malware and stealthy communication channels.
Code of Conduct: DPRK’s Python-fueled intrusions into secured networks
Investigating the DPRK’s strategic use of Python and carefully crafted social engineering, this publication sheds light on how they breach highly secure networks with evolving and effective cyber attacks.
Elastic releases the Detection Engineering Behavior Maturity Model
Using this maturity model, security teams can make structured, measurable, and iteritive improvements to their detection engineering teams..
Linux Detection Engineering - A Sequel on Persistence Mechanisms
In this final part of this Linux persistence series, we'll continue exploring persistence mechanisms on Linux systems, focusing on more advanced techniques and how to detect them.
Linux Detection Engineering - A primer on persistence mechanisms
In this second part of the Linux Detection Engineering series, we map multiple Linux persistence mechanisms to the MITRE ATT&CK framework, explain how they work, and how to detect them.
Beyond the wail: deconstructing the BANSHEE infostealer
The BANSHEE malware is a macOS-based infostealer that targets system information, browser data, and cryptocurrency wallets.
Dismantling Smart App Control
This article will explore Windows Smart App Control and SmartScreen as a case study for researching bypasses to reputation-based systems, then demonstrate detections to cover those weaknesses.
BITS and Bytes: Analyzing BITSLOTH, a newly identified backdoor
Elastic Security Labs identified a novel Windows backdoor leveraging the Background Intelligent Transfer Service (BITS) for C2. This malware was found during a recent activity group tracked as REF8747.
Introducing a New Vulnerability Class: False File Immutability
This article introduces a previously-unnamed class of Windows vulnerability that demonstrates the dangers of assumption and describes some unintended security consequences.
GrimResource - Microsoft Management Console for initial access and evasion
Elastic researchers uncovered a new technique, GrimResource, which allows full code execution via specially crafted MSC files. It underscores a trend of well-resourced attackers favoring innovative initial access methods to evade defenses.
