This CyberChef recipe extracts information from one or more lines of an Apache HTTP access log (combined log format) and outputs it formatted with labels.
The date is converted to ISO format and the time zone is changed to UTC.

CyberChef can extract URLs and e-mail addresses from a text. To read URLs and e-mail addresses from files - even recursively - you can use console commands.
The Windows console command
findstr /S "://" *.txt > urls.txt
oder under Linux the command
grep -Ihr --include="*.txt" "://" * > urls.txt
writes the lines from all text files that may contain a URL to the output file "urls.txt". The parameter "/S" or "-r" causes the recursive search in subdirectories. The output file is now loaded into CyberChef via drag and drop or with the open function as input. The following recipe outputs the URLs without duplicates and sorted.
Extract_URLs(false,true,true)
For e-mail addresses the procedure is very similar. The console command is called with a short regular expression:
findstr /S /R ".+@[a-z0-9]" *.txt > emails.txt
Oder unter Linux:
grep -EIihr --include="*.txt" ".+@[a-z0-9]" * > emails.txt
The output file is loaded into CyberChef. The recipe below outputs all email addresses without duplicates and sorted.
Extract_URLs(false,true,true)
With the Windows console command "type *.url > urls.txt" the contents of all .url files will be written to the file "urls.txt". After that load the following recipe in CyberChef:
[{"op":"Regular expression","args":["User defined","(?:^|[\\r\\n])\\[InternetShortcut\\][^\\[]*[\\r\\n]URL=([^\\r\\n]*)(?:[\\r\\n]|$)",true,true,false,false,false,false,"List capture groups"]}]
Move the file "urls.txt" via drag and drop onto the input field in CyberChef. In the output only those data are contained, which are entered in the line "URL" of the section "InternetShortcut".
Another method would be to extract all URLs with "Extract_URLs(false,true,true)". The output of the addresses is sorted and without duplicates.
From a list of email addresses, this recipe filters out those that are so-called disposable email addresses or temporary email addresses.

This recipe extracts the time of the search query from the data structure of the ei parameter of a Google URL. The recipe accepts the value itself or the entire URL as input.
The ei parameter is encoded with Base64 and contains in the first 4 bytes an unsigned integer in little-endian. This is a UNIX timestamp that coincides with the time of the search query. There is no verified description of this value from Google.
