Implementasi Penyembunyian Dokumen DOCX Menggunakan Enkripsi AES (Fernet) dan Teknik File Fusing Berbasis Python
type: item
description: This study discusses the implementation of a document concealment technique for DOCX files using a combination of AES (Fernet) encryption and a Python-based file fusing method. The main objective of this research is to enhance file-level data security by encrypting document content and embedding it within a host file (e.g., an image) without altering the functionality of the host file. The research methodology includes the analysis of the AES algorithm, encryption and decryption processes, the implementation of file fusing, and performance evaluation in terms of time efficiency and file size growth. The results show that this method effectively maintains document confidentiality while making the hidden data difficult to detect, with the combined file size increasing only by approximately 2–5% from the original host file. This system can be applied for securing confidential data in digital environments, particularly for online distribution of sensitive documents.

Implementasi Algoritma Least Significant Bit (LSB) untuk Penyembunyian Pesan Teks pada Media Citra Digital dan Audio Berbasis Python
type: item
description: Information security is a crucial aspect of modern digital data exchange. Conventional security techniques, such as cryptography, often raise suspicion from third parties due to the production of unreadable encrypted data. Therefore, steganography techniques are required to conceal the very existence of secret messages within other media. This study aims to design and build a Python-based steganography application capable of embedding text messages into PNG digital images and WAV audio formats. The method employed is the Least Significant Bit (LSB), which works by manipulating the rightmost bit of image pixel data or audio samples. The application is built using the Tkinter library for the interface, alongside Pillow and Wave for media processing. Black Box testing results indicate that the application successfully performs message encoding and decoding processes accurately without compromising data integrity. Perceptually, both visually and auditorily, the resulting steganographic media suffer no significant quality degradation, making it effective in deceiving human senses and maintaining information confidentiality.

Analisis Sistem Autentikasi Dua Faktor (2FA) Dan Efektivitasnya Dalam Meningkatkan Keamanan Akses
type: item
description: The rapid development of information technology has led to an increase in security threats to digital systems, particularly in user authentication mechanisms. Single-factor authentication based solely on passwords is no longer sufficient to protect system access from attacks such as phishing, brute force, and credential stuffing. Therefore, two-factor authentication (2fa) has emerged as a solution by adding an additional layer of security. This study aims to analyze the concept of 2fa and evaluate its effectiveness in improving system access security. The research method used is a literature study of various studies and implementations of 2fa in modern information systems. The results indicate that the implementation of 2fa significantly reduces the risk of unauthorized access and increases user trust in system security, despite challenges related to usability and technical implementation.

Implementasi Metode LSB (Least Significant Bit) Pada Aplikasi Steganografi Citra Untuk Pengamanan Pesan Teks
type: item
description: Keamanan informasi dalam pertukaran data digital saat ini menghadapi tantangan besar terkait risiko penyadapan oleh pihak yang tidak berwenang. Penelitian ini bertujuan untuk mengimplementasikan teknik steganografi menggunakan metode Least Significant Bit (LSB) untuk mengamankan pesan teks rahasia ke dalam media citra digital. Metode LSB dipilih karena kemampuannya menyisipkan bit data pada lapisan bit paling rendah dari piksel citra sehingga tidak mengubah kualitas visual secara signifikan (imperceptibility). Pengembangan aplikasi ini mencakup proses penyisipan (embedding) dan pengambilan kembali (extracting) pesan. Hasil pengujian menunjukkan bahwa aplikasi mampu mengekstraksi pesan dengan tingkat akurasi 100% tanpa adanya kerusakan data. Selain itu, analisis visual membuktikan bahwa citra hasil steganografi tetap terjaga kualitasnya dan sulit dibedakan dengan citra asli oleh indra penglihatan manusia, sehingga efektif dalam menjaga kerahasiaan informasi selama proses transmisi.

type: item
description: Phishing attacks continue to evolve into increasingly complex cyber threats, particularly with the emergence of Generative Artificial Intelligence (GenAI) technologies capable of producing realistic fraudulent content. This study highlights the ineffectiveness of traditional blacklist-based security methods in countering dynamic attacks that exploit both technical and psychological vulnerabilities of users. The objective of this research is to analyze the technical characteristics and masquerading patterns of current phishing attacks. Using a descriptive qualitative approach, this study examines 14 active phishing URL samples from the 2024-2025 period through URL Feature Analysis. The results indicate that 80% of the samples have adopted the HTTPS protocol to manipulate user trust. Furthermore, the study identifies a dominance of typosquatting techniques and the abuse of cheap Top-Level Domains (TLDs) that often bypass standard security detection. The research concludes that effective cyber defense requires the integration of adaptive strategies, combining intelligent Machine Learning-based detection systems with comprehensive security awareness training to mitigate risks associated with human error.

Tinjauan Literatur: Evaluasi Metode Least Significant Bit (LSB) dalam Steganografi Berdasarkan Alasan Penggunaan dan Efektivitasnya terhadap Keamanan Data Digital
type: item
description: The rapid development of information technology has facilitated the exchange of digital data, but it has also given rise to various threats to information security. Steganography is one technique used to hide confidential data, with the Least Significant Bit (LSB) method being the most widely used approach due to its simplicity. This article aims to evaluate the reasons for using the LSB method in steganography, its weaknesses, and its effectiveness in digital data security. This study uses the Systematic Literature Review (SLR) method by reviewing relevant scientific articles obtained through the Google Scholar database. The literature selection process was carried out systematically using the PRISMA protocol. The results of the study show that the LSB method is widely used because of its ease of implementation, processing speed, adequate insertion capacity, and ability to maintain the visual quality of the disguised image. However, this method has limitations, particularly low resistance to noise, lossy compression, image manipulation, and steganalysis attacks when used alone. Therefore, the LSB method is considered quite effective for visual concealment, but it needs to be combined with additional security techniques to improve digital data security.

Uji penetrasi jaringan wireless dan IoT dengan tools open - source pada lingkungan virtual
type: item
description: Wireless network security and Internet of Things (IoT) device vulnerabilities have become critical issues in the digital era, especially with the growing reliance on smart devices in household, industrial, and urban environments. Many IoT devices and Wi-Fi networks currently in use remain susceptible to various attacks such as sniffing, spoofing, and brute-force, which can be exploited by malicious actors to steal sensitive information or gain unauthorized control of devices remotely. This study aims to conduct penetration testing on wireless systems and IoT devices within a safe and controlled virtual environment to identify potential security loopholes. The methodology involves setting up a virtual testbed using VirtualBox and the Kali Linux operating system, employing open-source tools such as Aircrack-ng, Nmap, Bettercap, and Wireshark. Attack simulations were carried out on wireless network configurations and virtual IoT devices under common scenarios such as credential theft, traffic surveillance, and denial-of-service (DoS) attempts. The test results indicate that several IoT devices remain highly vulnerable to basic attacks such as sniffing and brute-force login attempts, while wireless networks using WPA2 encryption are also exploitable under certain conditions. These findings highlight the urgent need to improve network security through stronger encryption standards, network segmentation, and device hardening. This study is expected to serve as a reference for developing open-source-based cybersecurity defense systems to protect IoT ecosystems from increasingly sophisticated threats.

Perancangan Dan Implementasi Aplikasi Steganografi Gambar Berbasis GUI Untuk Keamanan Pesan
type: item
description: Steganography is one of the information hiding techniques aimed at maintaining message confidentiality by embedding secret data into digital media without causing noticeable visual changes. This research focuses on the design and implementation of an image steganography application with a Graphical User Interface (GUI) that enables users to embed and extract secret text messages from digital images easily and practically. The Least Significant Bit (LSB) method is employed as the main approach, where message bits are inserted into the least significant bits of image pixels without significantly altering the visual quality of the stego-image. The development stages include requirement analysis, system design, interface design, application implementation using the Python programming language, and functional testing of message embedding and extraction features. Experimental results show that the application is able to embed text messages into digital images successfully and the hidden messages can be retrieved correctly without data loss. In addition, the stego-images do not exhibit noticeable visual differences compared to the original images, indicating that the embedded messages are not easily detected. Therefore, the developed application is considered effective as a supporting tool for maintaining message confidentiality in digital communication.

Rancang Bangun Sistem Steganografi Multi-format LSB dan Enkripsi Fernet Berbasis Python
type: item
description: This research designs a data security system using Python by integrating Fernet Encryption and LSB Steganograph. The system features multi-format capabilities, allowing users to embed text or files into image and audio media. The process begins by encrypting data using a password-based key, which is then embedded into the least significant bits of the carrier media. Experimental results demonstrate that the system effectively maintains data confidentiality with high visual quality. However, the embedding capacity is strictly limited by the size of the carrier media; oversized files cannot be processed if they exceed the available LSB bit space. This system provides an effective solution for small to medium- scale data protection through double-layer security.

Implementasi Metode Steganografi Least Significant Bit (LSB) dalam Menyembunyikan Pesan Teks pada Citra Digital
type: item
description: In the digital era vulnerable to data security threats, Least Significant Bit (LSB) steganography emerges as an innovative technique for concealing sensitive text messages within digital images without altering visual perception. This study implements an adaptive LSB algorithm on 512x512 pixel grayscale and RGB images, employing random pixel selection based on a secret key to enhance resistance against statistical steganalysis. The embedding process converts text to binary and substitutes the LSB of the green channel, followed by reversible extraction achieving 100% accuracy under ideal conditions. Evaluation on standard datasets yields an average PSNR of 51.8 dB, MSE of 12.4, and embedding capacity up to 0.48 bpp, outperforming conventional LSB by 4-7% in imperceptibility and JPEG compression robustness (92% recovery rate). These findings affirm LSB's potential for practical information security applications, recommending hybrid cryptography integration to bolster resilience against adaptive attacks.

Implementasi Steganografi pada Citra Digital Menggunakan Metode Least Significant Bit (LSB) dengan Pengamanan Pesan Menggunakan Kriptografi Sederhana
type: item
description: Steganography is a technique used to conceal secret information within digital media in order to prevent unauthorized parties from detecting the existence of the message. One commonly used approach is the Least Significant Bit (LSB) method due to its simplicity and high imperceptibility. However, if the hidden message is successfully extracted, the confidentiality of its content may still be at risk. Therefore, this research implements a digital image steganography system using the LSB method, in which the secret message is first encrypted using a simple encryption mechanism before the embedding process. The encrypted message is then embedded into a digital image by modifying the least significant bits of pixel values. The developed web-based application allows users to embed and extract secret messages effectively. The results show that the embedding and extraction processes are successfully performed, and the stego image does not exhibit noticeable visual differences compared to the original image. These results indicate that the proposed approach can conceal secret messages while maintaining acceptable visual quality of the image.

type: item
description: Information security is a crucial aspect in the digital era, particularly in data transmission over the internet. In addition to cryptography, steganography serves as an alternative approach that conceals the existence of information itself. This study aims to design and implement a web-based digital steganography application by integrating the Least Significant Bit (LSB) method with the Advanced Encryption Standard (AES) algorithm. The LSB method is used to embed data into digital images by modifying the least significant bits, while AES encrypts the payload prior to embedding. The application is developed using PHP and a web-based interface. The results indicate that the system can embed text messages and document files into digital images without significantly affecting visual quality, and the hidden data can only be extracted using the correct password. Therefore, the integration of steganography and cryptography provides a dual-layer security mechanism for protecting digital information.

Rancang Bangun Aplikasi Steganografi Berbasis Web Menggunakan Metode Least Significant Bit (LSB) Dan XOR Untuk Enkripsi File Berbasis Citra
type: item
description: Data security is vital in digital exchange, yet standard Least Significant Bit (LSB) steganography remains vulnerable to unauthorized extraction. This study aims to develop a web-based steganography application combining LSB with Exclusive OR (XOR) encryption to enhance confidentiality. The proposed method involves encrypting secret data using XOR operations before embedding it into the cover image's LSB. The application is built on a web platform for accessibility, and the resulting image quality is evaluated using Mean Square Error (MSE) and Peak Signal-to-Noise Ratio (PSNR). The results demonstrate that the system successfully embeds and extracts data intactly. The obtained PSNR values exceed 40 dB, indicating that the stego-images maintain high visual fidelity indistinguishable from the original images, thereby offering a robust solution for secure data transmission.

Analisis Pengaruh Panjang Pesan terhadap Kualitas Citra pada Steganografi LSB
type: item
description: This study examines how variations in message length influence image quality in Least Significant Bit (LSB) steganography. Steganography embeds secret information into digital images, and LSB is one of the simplest and most widely applied techniques due to its low computational cost and ease of implementation. However, increasing the payload size may degrade the visual quality of the stego-image and make it more susceptible to detection. The objective of this research is to analyze the relationship between the amount of embedded data and the resulting image quality. The method involves embedding messages of different lengths into a set of test images using the LSB approach, followed by quantitative quality assessment through metrics such as Peak Signal-to-Noise Ratio (PSNR) and Mean Squared Error (MSE). Experimental results indicate that longer embedded messages lead to a gradual decline in visual quality, reflected by decreasing PSNR values and increasing MSE scores, although moderate payloads still maintain acceptable image fidelity. These findings highlight the trade-off between capacity and imperceptibility in LSB-based steganography and provide useful guidance for determining suitable message sizes in practical data-hiding applications.

Strategi Layanan Keamanan Siber pada Ekosistem Multi-Platform: Tinjauan Literatur
type: item
description: The rapid escalation of digital technology adoption has compelled modern organizations to operate within complex multi-platform ecosystems, integrating diverse operating systems, mobile devices, web applications, and cloud services. While this convergence enhances operational agility, it significantly expands the potential attack surface, exposing critical assets to sophisticated cyber threats. This study employs a Systematic Literature Review (SLR) methodology to evaluate and compare contemporary cybersecurity strategies. Analyzing 15 primary studies selected from reputable databases between 2018 and 2024, this research contrasts the efficacy of Perimeter-based models, Defense-in-Depth, and Zero Trust Architecture (ZTA). The findings demonstrate that traditional static security perimeters are obsolete in decentralized environments. Conversely, a hybrid approach combining Zero Trust with AI-driven threat detection offers superior resilience, reducing incident response latency and preventing lateral movement. The study concludes by proposing an integrated security framework that positions cybersecurity as a strategic business enabler rather than a technical support function.

Implementasi Teknik Least Significant Bit (LSB) dan File Injection untuk Pengamanan Data Berbasis Web
type: item
description: Keamanan pertukaran informasi di ruang siber menjadi tantangan besar seiring meningkatnya risiko penyadapan data sensitif oleh pihak yang tidak berwenang. Steganografi muncul sebagai solusi proteksi tingkat lanjut dengan menyembunyikan eksistensi pesan di dalam media digital lain sehingga tidak memicu kecurigaan. Penelitian ini bertujuan untuk merancang dan mengimplementasikan aplikasi "SteganoSafe" berbasis web yang mampu mengamankan data teks dan dokumen di dalam file gambar serta audio. Sistem ini dikembangkan menggunakan bahasa pemrograman Python dengan framework Flask, serta mengandalkan dua teknik utama: Least Significant Bit (LSB) dan File Injection. Pada metode LSB, pesan teks dikonversi menjadi biner dan disisipkan ke dalam bit paling tidak signifikan pada piksel gambar (format PNG/JPG) atau frame audio (format WAV). Proses ini memastikan bahwa perubahan pada media pembawa tidak dapat dideteksi secara visual maupun auditif oleh manusia. Di sisi lain, teknik File Injection memungkinkan penyisipan file dokumen seperti PDF atau ZIP dengan cara menggabungkan data biner file rahasia ke akhir file pembawa menggunakan separator unik sebagai penanda biner. Pengujian fungsional menunjukkan bahwa sistem berhasil melakukan enkapsulasi dan ekstraksi data dengan integritas 100% tanpa kerusakan data asli. Penggunaan antarmuka web modern dengan konsep glassmorphism memberikan kemudahan aksesibilitas dan pengalaman pengguna yang intuitif. Hasil penelitian menyimpulkan bahwa kombinasi algoritma LSB dan manajemen biner melalui platform web menyediakan mekanisme perlindungan data yang efisien, transparan, dan andal untuk kebutuhan komunikasi rahasia.

Implementasi Pengamanan Data Menggunakan Kombinasi Algoritma Kriptografi AES-256 dan Teknik Steganografi End-of-File (EOF) Pada Media Citra Digital
type: item
description: In the contemporary digital landscape, the security and confidentiality of information exchange have emerged as paramount concerns due to the increasing sophistication of cyber threats. This study proposes an integrated security framework through the development of "PrivaSel," a hybrid application that synergizes advanced cryptography and steganography to achieve dual-layer protection. The system employs the Advanced Encryption Standard (AES) with a robust 256-bit key length, implemented in Cipher Block Chaining (CBC) mode to ensure high-level data confidentiality and resistance against frequency analysis attacks. Key derivation is further strengthened using the PBKDF2 algorithm with 100,000 iterations and a random salt to mitigate brute-force vulnerabilities. For the covert layer, the system utilizes the End-of-File (EOF) steganography technique, which embeds encrypted payloads into diverse container media including images and videos without altering the spatial pixel data. Developed using a Python-based FastAPI backend and a responsive HTML5/Tailwind CSS frontend, the application facilitates seamless asynchronous processing. Empirical testing through histogram analysis confirms that the EOF method maintains absolute visual integrity, yielding a Mean Squared Error (MSE) of 0.00 and an infinite Peak Signal-to-Noise Ratio (PSNR). The results demonstrate that while the file size increases linearly relative to the payload and metadata overhead, the hidden information remains imperceptible to statistical analysis and can be flawlessly retrieved only with the authorized password, providing a reliable solution for secure multi-file data transmission.
