Telegram Bot is a chatbot platform that makes it easy to develop and integrate chatbots with Telegram. If you want to display the rest of the table, include the * wildcard.17 Open-source Free Self-hosted Telegram ChatGPT Bot Scripts If you wish to convert to local date and time: For example, the SQL query to convert the start_time in the downloads table to UTC time/date is shown in the following: With this logic in mind, you can convert the other timestamps in the Chrome History table to UTC or local time. To print the timestamps in last_visit_time in a UTC column and a local time column as well as printing the rest of the table, execute the following SQL command: Therefore, when executing the SQL command, the times in the last_visit_time column are divided by 1 million to convert microseconds to seconds, which are later subtracted by 11644473600 in order to get UNIX time, which is later converted to UTC. It turns out that the last_visit_time column in the urls table uses a WebKit Format time in which the timestamps are the number of microseconds since January 1, 1601. It is the number of seconds between Januand January 1, 1970. You may wonder what the number 11644473600 means. Click on the Execute SQL tab and type the following SQL query: To convert the timestamps to UTC time and date, we would need to execute SQL queries. You may notice the last_visit_time has timestamps. After opening the urls table, click on the Browse & Search tab to see the table. Īfter importing the History database file into SQLite Manager, there are nine tables, two of which are the downloads and urls tables. You can use the SQLite Database Browser, or you can use the SQLite Manager plugin for Firefox, which is what I used. This is a well-written and informative post, David! I would like to share a more efficient method of converting the visited times. Opening the History file with this Database Browser displays the structure which is also described by SANS. We know information about seconds are available from the NirSoft tools, so why doesn't ChromeForensics provide these details? I'm not sure, but taking a suggestion from the SANS post and remembering how the History file is just an SQLite database, we can just use an SQLite database browser GUI such as the one found at for free. There must be some way to get the seconds field at least, right?ĬhromeForensics can be downloaded at for free. A bigger problem for me concerns the timestamps provided not including a seconds field. One minor annoyance is a clunky GUI when manipulating column positions. History of downloaded files can be especially useful in an investigation. You can see now that even more information is provided by this tool. Quick analysis shows the f_ files are the webpage objects while the data_ and index files contain metadata apparently for the f_ files. Looking at the objects in this directory with a forensic tool will allow you to see the file signatures and contents. This directory should contain several files named data_0, data_1, and so on many files named f_000001, f_000002, and so on and a file named index. The Chrome cache can be found in the following location inside the Chrome folder: NirSoft's other Chrome specific tool is able to parse Chrome's cache of webpage objects saved from the user's browsing activity. This tool is capable of grabbing history from FireFox, Chrome, IE, and more all at once from a running system, just a user on the running system, or an evidence folder containing the evidence files. NirSoft also offers a tool called Browser History View that can be downloaded from. NirSoft Chrome History View can be downloaded from for free. You can then Ctrl + C or right click to copy and paste the data right into Excel for powerful manipulation. From this view, the data is easily selected with your favorite selection techniques including Ctrl + A, Shift + Click, and Ctrl + Click.
