This guide explains how a file deleted on a Linux system can still be recovered when a running process holds an open file descriptor, detailing the use of tail, lsof, the /proc filesystem, and simple copy commands to restore the data.
This guide outlines eleven practical steps for Linux system administrators to identify signs of compromise—such as missing logs, altered password files, unusual login activity, abnormal traffic, and deleted files—and provides command examples for detection and recovery.
This article explains how deleted files remain on storage until overwritten, describes the role of the file allocation table and magic numbers, and provides step‑by‑step instructions for using TestDisk, command‑line tools, and secure‑delete utilities to recover or permanently erase files on Linux systems.
This guide explains why deleted files remain recoverable, how file allocation tables and magic numbers enable recovery, and provides step‑by‑step instructions for using TestDisk, handling device names, restoring open files, and securely erasing data on Linux systems.
This guide explains why careful file deletion matters, introduces Linux tools like lsof and extundelete for recovering mistakenly removed files, and provides step‑by‑step commands, installation instructions, and precautions to maximize recovery success while avoiding data loss.
This guide explains why careless file deletion can cause serious loss, introduces Linux tools like lsof and extundelete for recovering deleted files, and provides step‑by‑step commands for installing, locating open file descriptors, and restoring individual or all deleted data safely.
This guide explains why deleted files remain on storage, how recovery tools locate them using file system metadata and magic numbers, and provides step‑by‑step instructions for using TestDisk, handling various partition tables, recovering files from ReiserFS, and extracting open‑deleted files directly from RAM.
This guide walks Linux operations engineers through common signs of a compromised host—such as missing logs, altered password files, unexpected login events, and deleted critical files—and provides concrete command‑line techniques for detection, investigation, and recovery using tools like ll, du, lastlog, who, lsof, and tcpdump.
This guide explains why careful file deletion matters, introduces Linux tools like lsof and extundelete for recovering accidentally removed files, and provides step‑by‑step commands, installation instructions, and precautions to successfully restore data from ext3/ext4 partitions.
This guide explains why careless file deletion can be disastrous, then walks through two Linux recovery techniques—using lsof to capture still‑open deleted files and employing extundelete to restore data from ext3/ext4 partitions—complete with commands, parameters, and practical tips.
This guide explains how to restore accidentally deleted files on Linux by handling two scenarios—when the deleting process still holds an open file descriptor and when it has terminated—using lsof, /proc tricks, and the extundelete utility with step‑by‑step commands.
This guide explains how to restore mistakenly removed Linux files by first checking if the deleting process still holds the file descriptor using lsof, then copying the open file from /proc, and finally using the extundelete tool when the process has already terminated.
This guide explains how to restore accidentally deleted Linux files, covering both scenarios where the file is still held open by a running process using /proc and lsof, and where the process is gone, requiring tools like extundelete with step‑by‑step commands.
Learn how Git tracks modifications instead of files, and discover step‑by‑step techniques to discard unadded changes, revert staged edits, delete files, and restore removed or altered files using commands like git checkout, git reset, git rm, and git reflog, with practical examples and screenshots.
This guide outlines ten practical methods for Linux administrators to identify compromised machines on CentOS, including log inspection, checking /etc/passwd and /etc/shadow, analyzing login records, monitoring network traffic, and using lsof to recover deleted log files, with step‑by‑step commands and examples.
This guide walks you through preparing a Linux disk, safely protecting the partition, installing extundelete, and using it to restore both files and directories that were mistakenly removed, providing practical commands and screenshots for each stage.
This guide walks Linux administrators through common signs of server compromise, shows how to examine logs, user files, active processes, network traffic, and demonstrates using lsof and /proc to recover deleted log files, all with concrete command examples.
This guide walks Linux operations engineers through common signs of a breached machine, showing how to examine logs, verify user files, monitor login events, use lsof for deleted files, and recover critical logs with step‑by‑step commands.
