Keylogger
A keylogger, also known as a keystroke logger, is a tool—either software or hardware—that records every keystroke made on a keyboard, typically without the user’s knowledge. The primary purpose of a keylogger is to capture sensitive information such as passwords, credit card numbers, messages, and other confidential data that users type into their devices. This information is often sent to a remote attacker, who can use it for identity theft, financial fraud, or unauthorized access to systems.
Types of Keyloggers
Software Keyloggers
These are malicious programs installed on a device, often through infected downloads, email attachments, or compromised websites. Once active, they run in the background, intercepting and recording keystrokes. Advanced software keyloggers can also capture screenshots, clipboard contents, and even audio or video from the device’s microphone or camera.
Hardware Keyloggers
These are physical devices connected between a keyboard and a computer, or embedded inside the keyboard itself. They record keystrokes directly from the hardware and store the data for later retrieval. Hardware keyloggers require physical access to the device to install and collect data, but they are generally harder to detect than software versions.
How Keyloggers Work
• Recording Keystrokes: Keyloggers monitor and log every key pressed on the keyboard.• Data Storage/Transmission: The captured data is saved to a file, which may be accessed locally or sent remotely to an attacker.• Additional Features: Some keyloggers can also capture screenshots, clipboard data, or even audio and video inputs
Detection and Protection
Detecting keyloggers can be challenging, especially for advanced variants that operate at the kernel level or are embedded in hardware. Specialized anti-keylogger software and regular security scans can help identify and remove software-based keyloggers. Physically inspecting hardware connections can help detect hardware-based keyloggers.
Keylogging
Keylogging (or keystroke logging) is the practice of recording every key pressed on a keyboard, usually without the user’s knowledge or consent. The primary goal is to capture sensitive information such as passwords, credit card numbers, personal messages, and other confidential data as they are typed.
Types of Keyloggers
There are two main types of keyloggers:• Software Keyloggers: Malicious programs installed on a device, often delivered through infected downloads, email attachments, or compromised websites. These can operate at various levels, such as intercepting keyboard input via system hooks, monitoring API calls, or even running at the kernel level for deeper access. Software keyloggers can also periodically send the captured data to remote attackers.• Hardware Keyloggers: Physical devices connected between the keyboard and the computer, or embedded inside the keyboard itself. These require physical access to install and cannot spread like software, but they also record keystrokes and store or transmit the data for later retrieval.
Uses of Keyloggers
Keyloggers can be used for both legitimate and malicious purposes:• Legitimate uses: Employers monitoring employee activity, parents supervising children, or IT departments troubleshooting devices.• Malicious uses: Cybercriminals use keyloggers to steal login credentials, financial information, and other private data for identity theft or fraud.
Impact and Risks
Keyloggers pose a significant security risk because they can covertly capture vast amounts of sensitive information. Advanced keyloggers may also record screenshots, clipboard contents, and even audio or video from a device’s microphone or camera.
Known Exploited Vulnerabilities
The Known Exploited Vulnerabilities catalog (KEV) is an authoritative, publicly available list of security vulnerabilities that have been actively exploited in the wild. Maintained by the Cybersecurity and Infrastructure Security Agency (CISA) in partnership with organizations like NIST and MITRE, the KEV catalog is designed to help organizations prioritize remediation efforts by focusing attention on vulnerabilities that present the most immediate and significant risks.
Key characteristics of the KEV catalog:
Includes only vulnerabilities with evidence of active exploitation by malicious actors, based on analysis from security vendors, researchers, government, and open-source reporting.
Each entry has an assigned CVE ID (Common Vulnerabilities and Exposures identifier) and clear, actionable remediation guidance, such as vendor patches or mitigation steps.
The catalog is updated regularly as new exploited vulnerabilities are identified and confirmed.
Federal civilian executive branch (FCEB) agencies are required by law (Binding Operational Directive 22-01) to remediate KEV-listed vulnerabilities within set timeframes, but CISA strongly encourages all organizations—including those in the private sector and state/local governments—to use the catalog to enhance their security posture.
Benefits and usage:
Prioritization: By focusing on vulnerabilities that are already being exploited, organizations can allocate resources more efficiently and reduce the risk of compromise.
Actionable intelligence: The catalog provides detailed information, including affected products, exploitation status (such as use in ransomware campaigns), and links to vendor advisories or patches.
Community defense: By addressing KEV-listed vulnerabilities, organizations contribute to the overall resilience of the cybersecurity ecosystem.
How to access and use:
The KEV catalog is freely available in formats like CSV and JSON for easy integration with vulnerability management tools.
Organizations are encouraged to subscribe to updates and incorporate KEV entries into their vulnerability management and patching workflows.
L2FL2F, or Layer 2 Forwarding, is a network tunneling protocol developed by Cisco Systems. Its primary purpose is to enable the creation of Virtual Private Networks (VPNs) by tunneling data-link layer frames—such as those from Point-to-Point Protocol (PPP) or Serial Line Internet Protocol (SLIP)—over public or private networks, most commonly the Internet.
L2F functions at the Data Link Layer (Layer 2) of the OSI model, encapsulating data frames for transmission across IP networks. It establishes a tunnel between a remote user’s network and a central site (such as a corporate network), making it appear as if the remote user is directly connected to the private network. L2F was specifically designed to tunnel PPP traffic, allowing ISPs or network access servers (NAS) to forward PPP frames from clients to remote nodes (often called “home gateways”). L2F is not tied to IP and can also operate over other network types, such as Frame Relay or ATM.
L2TP
L2TP (Layer 2 Tunneling Protocol) is a network protocol primarily used to support Virtual Private Networks (VPNs) and to facilitate secure data transmission over public networks such as the internet. It operates at the data link layer (Layer 2) of the OSI model, encapsulating data packets to create a tunnel between two endpoints—typically a client device and a VPN server.
The two main components in an L2TP connection are: (1) L2TP Access Concentrator (LAC): The entry point for the tunnel, usually at the client or ISP side. (2) L2TP Network Server (LNS): The endpoint that receives, decapsulates, and forwards the data to the target network.
Transport: L2TP packets are typically transmitted over UDP, which helps avoid certain network issues like TCP meltdown. L2TP does not provide encryption or strong authentication by itself. For security, it is almost always paired with IPsec (Internet Protocol Security), which adds encryption, authentication, and integrity checks. This combined protocol is commonly referred to as L2TP/IPsec
LapDogs
The LapDogs infrastructure is a covert cyber-espionage network attributed to China-nexus threat actors. It represents a sophisticated and methodically expanding Operational Relay Box (ORB) network, primarily targeting Small Office/Home Office (SOHO) routers and Internet of Things (IoT) devices globally, with a particular focus on the United States and key regions in Southeast Asia, including Japan, South Korea, Taiwan, and Hong Kong.
Key Characteristics of LapDogs
Operational Relay Box (ORB) Network• Unlike traditional botnets, ORB networks like LapDogs use compromised devices as stealthy relay points for long-term, covert infrastructure rather than for launching noisy, disruptive attacks.• These compromised devices continue to function normally, making detection and attribution challenging.
Infection and Persistence• LapDogs leverages a custom backdoor called “ShortLeash,” which is compatible with both Linux and Windows systems.• ShortLeash installs itself as a system service, often with root privileges, ensuring persistence even after device reboots.• The malware mimics legitimate services (e.g., Nginx web server) and generates unique, self-signed TLS certificates that spoof the Los Angeles Police Department (LAPD) to blend malicious traffic with legitimate activity.
Targeting and Scale• Over 1,000 devices have been identified as actively infected, with infections organized into 162 distinct intrusion sets.• The campaign is highly targeted, focusing on specific regions, ISPs, and industries such as IT, networking, real estate, and media.• Most compromised devices are older or unpatched SOHO routers, particularly from Ruckus Wireless (about 55% of infections) and Buffalo Technology.
Exploitation Techniques• LapDogs exploits known vulnerabilities in lightweight web servers and management interfaces commonly found in SOHO devices, such as CVE-2015-1548 and CVE-2017-17663.• The attackers use dual-layer encryption and UCL-like compression to conceal the malware payload and its configuration, which includes certificates, private keys, and command-and-control (C2) URLs.
Attribution and Intent• Forensic evidence, including Mandarin developer notes and region-specific targeting, supports attribution to China-nexus Advanced Persistent Threats (APTs).• The campaign is deliberate and goal-oriented, with expansion occurring in small,(...)
LARAVELLaravel is a free, open-source PHP web application framework designed to make building web applications easier and more efficient. It provides developers with a set of tools and resources—such as pre-built components, libraries, and an organized structure—that allow them to focus on building features rather than handling repetitive, low-level tasks.
Key points about Laravel:
Backend Framework: Laravel is primarily used for backend development, handling things like data storage, authentication, routing, and server-side logic.
MVC Architecture: It follows the Model-View-Controller (MVC) architectural pattern, which separates the application into three main components: models (data), views (user interface), and controllers (logic), making code more organized and maintainable.
Expressive Syntax: Laravel is known for its elegant and readable syntax, which aims to make development enjoyable and less error-prone.
Built-in Features: It includes features such as routing, authentication, database management, RESTful API support, and a command-line tool called Artisan for automating tasks.
Extensibility: Laravel can be extended with packages and integrates easily with frontend frameworks like Vue.js or React for building modern, interactive applications.
Community and Ecosystem: Laravel has a large, active community and a rich ecosystem of official and third-party packages, making it a popular choice for PHP developers.
In simple terms, if PHP is like a box of Lego bricks, Laravel is a collection of ready-made Lego structures—like doors, windows, and wheels—that help you build complex models (web applications) faster and with less effort.
Laravel is suitable for a wide range of projects, from small websites to large, enterprise-grade applications, and is widely used in the industry due to its balance of power, flexibility, and ease of use.
APT38Lazarus Group is a North Korean state-sponsored cyber threat organization attributed to the Reconnaissance General Bureau (RGB), the country’s primary military intelligence division. Active since at least 2009, Lazarus is considered one of the world’s most prolific and destructive hacking collectives, operating both as an agent of state espionage and as a tool for generating illicit revenue to support North Korea’s sanctioned regime.
Lazarus uses a wide array of custom malware (e.g., Appleseed, HardRain, Fallchill, Joanap), ransomware (WannaCry), and advanced social engineering tactics. They are adept at quickly repackaging malware, switching encryption keys, deleting logs, and employing disk-wiping malware for maximum disruption. Money laundering is conducted through decentralized platforms and mixers like Tornado Cash to obfuscate the origins of stolen cryptocurrency.
Key Motivations and Activities
• Financial Theft: Lazarus is infamous for massive financial heists, targeting banks, cryptocurrency exchanges, and fintech firms to generate revenue for the North Korean regime and fund its missile and nuclear programs.• Espionage: The group targets governments, defense contractors, critical infrastructure, and research organizations for intelligence collection.• Sabotage and Disruption: Lazarus has conducted destructive attacks, including the Sony Pictures hack (2014) and the global WannaCry ransomware outbreak (2017).
Structure and Subgroups
• Bluenoroff (APT38): Specializes in financial heists, including SWIFT and cryptocurrency attacks.• Andariel: Focuses on espionage against businesses, government agencies, and critical infrastructure.• TEMP.Hermit: Conducts strategic intelligence gathering, especially against government and defense targets.
Tactics, Techniques, and Procedures (TTPs)
• Initial Access: Spear-phishing, supply chain compromise, exploitation of zero-day vulnerabilities, and watering hole attacks.• Malware Arsenal: Custom malware families such as MagicRAT, QuiteRAT, ThreatNeedle, LPEClient, and ransomware variants.• Lateral Movement: Use of RDP, PSExec, SMB, and exploitation of vulnerabilities like Log4Shell (CVE-2021-44228).• Data Exfiltration: Exfiltration via C2 channels, cloud storage (Dropbox), and encrypted protocols.• Obfuscation: Use of VPNs (notably Astrill VPN), proxies, and anti-forensic techniques to evade(...)
LDAPLightweight Directory Access Protocol (LDAP) is an open, vendor-neutral application protocol used to access and manage directory information services over a network. In essence, LDAP provides a standardized way for applications and users to query, search, and modify information stored in directory services—these directories typically hold data such as usernames, passwords, email addresses, device locations, and more.
LDAP operates on a client-server model: clients send requests to an LDAP server, which manages the directory data and responds to queries. The protocol is designed for fast retrieval (read) of data that doesn’t change often, making it ideal for storing static information like user credentials and organizational resources. LDAP directories are often structured hierarchically, similar to a tree, with branches representing different organizational units, users, or devices. LDAP can be used for both querying information (e.g., finding a user’s email address) and authentication (e.g., verifying usernames and passwords for access control).
Least Privilege
The principle of least privilege (PoLP) is a foundational information security concept that dictates users, applications, systems, or devices should be granted only the minimum access rights or permissions necessary to perform their required tasks—nothing more. This means that every entity in an IT environment, whether human or non-human, operates with the least amount of privilege needed to function, reducing the risk of accidental or intentional misuse of sensitive resources.
LLM
A Large Language Model (LLM) is a type of artificial intelligence (AI) system designed to understand, process, and generate human language. LLMs are built using deep learning techniques—specifically, a neural network architecture called a transformer—and are trained on vast amounts of text data, often sourced from the internet, books, articles, and other large-scale datasets. Examples of LLMs include ChatGPT, Bard, Gemini, Llama, Bing Chat, and GitHub Copilot.
LLM Scope ViolationLLM Scope Violation refers to situations where an LLM (like GPT-4 or similar models) operates outside its intended or authorized boundaries. From a technical and security standpoint, a scope violation typically means the LLM is performing actions or generating outputs that exceed the permissions, use cases, or safety constraints set by its developers or users.
LLM scope violationsLLM scope violations refer to security vulnerabilities in large language model (LLM) systems where the model is manipulated into accessing or leaking information beyond its intended operational boundaries. This occurs when untrusted or malicious inputs are mixed with sensitive internal data, causing the LLM to process and reveal privileged information to unauthorized parties.
Mixing Untrusted and Trusted Data: LLMs, especially those integrated with retrieval-augmented generation (RAG) or agentic frameworks, often combine external (untrusted) inputs—such as emails, documents, or web content—with internal (trusted) enterprise data. If the system fails to properly isolate these trust boundaries, an attacker can craft inputs that trick the LLM into including sensitive information in its output.
Indirect Prompt Injection: Attackers embed malicious instructions in content that the LLM might access, such as emails or meeting notes. When the LLM processes this content, it may inadvertently execute the attacker’s instructions, leading to data leakage.
Zero-Click Exploits: Some attacks, like EchoLeak, require no user interaction. For example, an attacker sends a specially crafted email to a target. When an employee later asks the LLM (e.g., Microsoft 365 Copilot) a business question, the system retrieves and processes the email, triggering the exploit and leaking sensitive data without any clicks or explicit user actions.
LockBitLockBit is a ransomware-as-a-service (RaaS) operation that emerged in 2019 and quickly became one of the most prolific and damaging ransomware groups globally. Its business model relies on leasing ransomware infrastructure—malware, payment portals, and leak sites—to affiliates, who then carry out attacks and share ransom proceeds with the core group. LockBit’s double-extortion tactics, encrypting data and threatening public leaks, have targeted sectors including healthcare, education, and critical infrastructure.
By 2022, LockBit was responsible for 44% of all ransomware incidents worldwide and was the most widely deployed ransomware variant, according to U.S. government agencies. In the U.S. alone, LockBit was used in about 1,700 attacks from 2020 to 2023, with $91 million paid in ransoms. Its cumulative ransom demands have reached into the hundreds of millions of dollars.

Memory InjectionMemory injection is a cybersecurity attack technique where an attacker inserts malicious code into the memory space of a running process or application on a computer. This type of attack exploits vulnerabilities in software or operating systems, allowing the injected code to execute within the context of the target process. As a result, the malicious code can perform unauthorized actions, such as stealing data, installing additional malware, or gaining elevated privileges, all while potentially evading detection by security software.
Key Points about Memory Injection
Memory injection is the act of inserting malicious code into the memory address space of a legitimate process or application. The main objective is to manipulate the behavior of the target application, execute arbitrary code, or escalate privileges without modifying files on disk.
Common Techniques
DLL Injection: Forcing a legitimate process to load a malicious Dynamic-Link Library (DLL), which can then execute arbitrary code.• Code Injection: Directly writing malicious code (often shellcode) into the memory of a target process.• Heap Spraying: Filling the process’s heap memory with malicious code to increase the likelihood of execution, often used in browser exploits.• Process Hollowing: Creating a new process in a suspended state, replacing its memory with malicious code, and then resuming the process.
Impact
Memory injection can lead to data theft, system compromise, unauthorized access, and privilege escalation. It is difficult to detect because the malicious code may only exist in memory and not on disk.
Detection and Prevention
Regular updates, security software, application whitelisting, and robust memory management policies can help mitigate the risk of memory injection attacks.
How Memory Injection Works
1. Identify a Vulnerable Process: The attacker finds a process with exploitable weaknesses.2. Inject Malicious Code: The attacker uses one of the above techniques to insert code into the process’s memory.3. Execute Malicious Code: The injected code runs with the same privileges as the target process, often bypassing security controls.4. Achieve Objectives: The attacker may steal data, install malware, or gain persistent access to the system.
Memory injection is a significant threat because it allows attackers to operate stealthily and with elevated(...)
MITRE ATT&CK framework
The MITRE ATT&CK framework is a globally accessible, continuously updated knowledge base that catalogs the tactics, techniques, and procedures (TTPs) used by cyber adversaries, based on real-world observations. ATT&CK stands for Adversarial Tactics, Techniques, and Common Knowledge. Developed by the MITRE Corporation in 2013, its primary purpose is to help organizations model, detect, prevent, and respond to cybersecurity threats by understanding how attackers operate—not just what artifacts they leave behind.
Core Components of MITRE ATT&CK
• Tactics: The why—these are the adversary’s technical objectives or goals during an attack, such as Initial Access, Privilege Escalation, or Command and Control.• Techniques: The how—specific methods adversaries use to achieve their tactical objectives, such as phishing, credential dumping, or lateral movement.• Sub-techniques: More granular variants of techniques, providing detailed insight into the specific ways a technique can be carried out (e.g., different forms of password guessing).• Procedures: Real-world examples of how threat actors have used these techniques in actual attacks.
Key Features and Benefits
• Behavioral Focus: Unlike traditional models that emphasize indicators of compromise (IoCs), ATT&CK focuses on adversary behavior, enabling defenders to detect and mitigate attacks even as attackers change their tools or infrastructure.• Standardized Vocabulary: ATT&CK provides a common language for describing threats, facilitating collaboration among security teams, vendors, and researchers worldwide.• Community-Driven and Open: The framework is freely available and continuously updated with contributions from the global cybersecurity community.• Practical Applications: Organizations use ATT&CK to simulate cyberattacks, test defenses, inform security policies, guide incident response, and enhance the configuration of security technologies like SIEM, XDR, and SOAR platforms.
Multi-factor AuthenticationMulti-factor authentication (MFA) is a security process that requires users to provide two or more independent forms of verification to prove their identity before gaining access to an account, application, or system. This approach significantly increases security by adding extra layers of defense beyond just a username and password, making it much harder for unauthorized users to access sensitive information—even if they have obtained your password.
The most common categories of authentication factors are:
Something you know: Such as a password, PIN, or answer to a security question.
Something you have: Such as a smartphone app that generates one-time codes, a hardware security key, or a smart card.
Something you are: Biometric identifiers like fingerprints, facial recognition, or retinal scans.
To successfully log in with MFA enabled, a user must present at least two of these different types of evidence. For example, after entering a password (something you know), you might also need to enter a code sent to your phone (something you have) or use your fingerprint (something you are).
Mustang Panda
Mustang Panda is a China-based cyber espionage group, active since at least 2012, though some sources suggest operations may date back even earlier. The group is also known by aliases such as Bronze President, RedDelta, Earth Preta, and Camaro Dragon. Mustang Panda targets a wide range of organizations, including governments, non-governmental organizations (NGOs), think tanks, and religious groups, primarily in the U.S., Europe, and across Asia—with particular focus on regions of strategic interest to China, such as Taiwan, Hong Kong, Mongolia, Myanmar, and Tibet.
Tactics, Techniques, and Procedures (TTPs)
Mustang Panda is notorious for highly tailored spear-phishing campaigns, using lures that mimic legitimate documents and exploit current events relevant to the target. The group commonly employs remote access trojans (RATs) like PlugX, Poison Ivy, and custom backdoors such as PUBLOAD and Pubshell. In recent years, they have increasingly used intermediate payloads, stagers, and reverse shells to maintain persistence and evade detection.
Attack chains often involve benign executables used to sideload malicious DLLs, which then deploy the final payload. Mustang Panda has a history of rapidly exploiting newly disclosed vulnerabilities, such as CVE-2017-0199, to compromise systems before patches can be applied.
Motivation and Scope
The group’s primary objective is intelligence gathering to support Chinese state interests, including the Belt and Road Initiative and Made in China 2025. Mustang Panda has targeted entities in over 30 countries, including Australia, India, Russia, and many nations in Europe and Southeast Asia. Recent Campaigns Recent activities have included attacks using conference- and summit-themed lures, as well as leveraging geopolitical events such as the conflict in Ukraine and issues related to Tibetan and Mongolian diaspora organizations. The group is known for continuously evolving its tools and techniques to stay ahead of detection and maintain long-term access to victim networks.

Network-Based IDS
A network-based IDS system monitors the traffic on its network segment as a data source. This is generally accomplished by placing the network interface card in promiscuous mode to capture all network traffic that crosses its network segment. Network traffic on other segments, and traffic on other means of communication (like phone lines) can't be monitored. Network-based IDS involves looking at the packets on the network as they pass by some sensor. The sensor can only see the packets that happen to be carried on the network segment it's attached to. Packets are considered to be of interest if they match a signature.Network-based intrusion detection passively monitors network activity for indications of attacks. Network monitoring offers several advantages over traditional host-based intrusion detection systems. Because many intrusions occur over networks at some point, and because networks are increasingly becoming the targets of attack, these techniques are an excellent method of detecting many attacks which may be missed by host-based intrusion detection mechanisms.
NULL Byte
A null byte refers to the character with the value 0x00 in hexadecimal (or %00 in URL encoding). It is used in many programming languages, especially C and C-derived languages, to indicate the end of a string. This means that when a null byte is encountered, the program treats it as the end of the input, ignoring any characters that follow.
Null byte injection is an exploitation technique where an attacker inserts a null byte into user-supplied data, often to bypass input validation or filtering mechanisms. This works because some programming languages or system functions (like those in C/C++) stop processing input at the null byte, while others (like PHP, Java, or Perl) may not treat it as special and continue processing the entire string.
Attackers can use null byte injection to:
Bypass file extension checks: For example, if an application appends ".php" to a filename, supplying "malicious.txt%00" can trick the system into only considering "malicious.txt" if the underlying code stops at the null byte.
Access restricted files: By injecting a null byte, attackers can manipulate file paths to access sensitive files like /etc/passwd on Unix systems.
Circumvent input validation: Filters that don't account for null bytes may allow otherwise forbidden input through, enabling further attacks such as directory traversal or code execution.
Example scenario:If a PHP application includes a file based on user input and appends ".php" to the filename, an attacker could exploit this with:
http://example.com/page.php?file=../../../../etc/passwd%00
The underlying C function might interpret it as /etc/passwd, ignoring the appended ".php" due to the null byte, and include the sensitive file.
