plaso.parsers.text_plugins.android_logcat module

Text parser plugin for Android logcat files.

Android logcat can have a number of output formats. This parser supports: * ‘threadtime’ format * ‘time’ format

The log file format is: date time PID-TID/package priority/tag: message

For example: 12-10 13:02:50.071 1901-4229/com.google.android.gms V/AuthZen: Handling delegate intent.

Where priority is: V: Verbose (lowest priority) D: Debug I: Info W: Warning E: Error A: Assert

In addition, support for the format modifiers: * date with a year * user identifier (uid) * microseconds fraction of second precision (usec) * time zone offset

This parser stores the “target_port_list” data in the “destination_list” attribute of an EventData object.

plaso.parsers.text_plugins.popcontest module

Text parser plugin for popularity contest log files.

Information updated 20 january 2014. From Debian Package Popularity Contest Avery Pennarun <apenwarr@debian.org>

From ‘https://www.unix.com/man-page/Linux/8/popularity-contest’:

The popularity-contest command gathers information about Debian pack- ages installed on the system, and prints the name of the most recently used executable program in that package as well as its last-accessed time (atime) and last-attribute-changed time (ctime) to stdout.

When aggregated with the output of popularity-contest from many other systems, this information is valuable because it can be used to deter- mine which Debian packages are commonly installed, used, or installed and never used. This helps Debian maintainers make decisions such as which packages should be installed by default on new systems.

The resulting statistic is available from the project home page https://popcon.debian.org

Normally, popularity-contest is run from a cron(8) job, /etc/cron.daily/popularity-contest, which automatically submits the results to Debian package maintainers (only once a week) according to the settings in /etc/popularity-contest.conf and /usr/share/popularity- contest/default.conf.

From ‘https://popcon.ubuntu.com/README’:

The popularity-contest output looks like this:

POPULARITY-CONTEST-0 TIME:914183330 ID:b92a5fc1809d8a95a12eb3a3c8445 914183333 909868335 grep /bin/fgrep 914183333 909868280 findutils /usr/bin/find 914183330 909885698 dpkg-awk /usr/bin/dpkg-awk 914183330 909868577 gawk /usr/bin/gawk […more lines…] END-POPULARITY-CONTEST-0 TIME:914183335

The first and last lines allow you to put more than one set of popularity-contest results into a single file and then split them up easily later.

The rest of the lines are package entries, one line for each package installed on your system. They have the format:

<atime> <ctime> <package-name> <mru-program> <tag>

<package-name> is the name of the Debian package that contains <mru-program>. <mru-program> is the most recently used program, static library, or header (.h) file in the package.

<atime> and <ctime> are the access time and creation time of the <mru-program> on your disk, respectively, represented as the number of seconds since midnight GMT on January 1, 1970 (i.e. in Unix time_t format). Linux updates <atime> whenever you open the file; <ctime> was set when you first installed the package.

<tag> is determined by popularity-contest depending on <atime>, <ctime>, and the current date. <tag> can be RECENT-CTIME, OLD, or NOFILES.

RECENT-CTIME means that atime is very close to ctime; it’s impossible to tell whether the package was used recently or not, since <atime> is also updated when <ctime> is set. Normally, this happens because you have recently upgraded the package to a new version, resetting the <ctime>.

OLD means that the <atime> is more than a month ago; you haven’t used the package for more than a month.

NOFILES means that no files in the package seemed to be programs, so <atime>, <ctime>, and <mru-program> are invalid.’

REMARKS. The parser will generate events solely based on the <atime> field and not using <ctime>, to reduce the generation of (possibly many) useless events all with the same <ctime>. Indeed, that <ctime> will be probably get from file system and/or package management logs. The <ctime> will be reported in the log line.

plaso.parsers.text_plugins.xchatlog module

Text parser plugin for XChat log files.

Information updated 24 July 2013.

The parser applies to XChat log files. Despite their apparent simplicity it’s not straightforward to manage every possible case. XChat tool allows users to specify how timestamp will be encoded (using the strftime function), by letting them specify additional separators. This parser will accept only the simplest default English form of an XChat log file, as the following:

**** BEGIN LOGGING AT Mon Dec 31 21:11:55 2001
dec 31 21:11:55 --> You are now talking on #gugle
dec 31 21:11:55 --- Topic for #gugle is plaso, nobody knows what it means
dec 31 21:11:55 Topic for #gugle set by Kristinn
dec 31 21:11:55 --- Joachim gives voice to fpi
dec 31 21:11:55 *   XChat here
dec 31 21:11:58 <fpi> ola plas-ing guys!
dec 31 21:12:00 <Kristinn> ftw!

It could be managed the missing month/day case too, by extracting the month/day information from the header. But the parser logic would become intricate, since it would need to manage day transition, chat lines crossing the midnight. From there derives the last day of the year bug, since the parser will not manage that transition.

Moreover the strftime is locale-dependent, so month names, footer and headers can change, even inside the same log file. Being said that, the following will be the main logic used to parse the log files (note that the first header must be ‘**** BEGIN …’ otherwise file will be skipped).

1) Check for ‘****’ 1.1) If ‘BEGIN LOGGING AT’ (English) 1.1.1) Extract the YEAR 1.1.2) Generate new event start logging 1.1.3) set parsing = True 1.2) If ‘END LOGGING’ 1.2.1) If parsing, set parsing=False 1.2.2) If not parsing, log debug 1.2.3) Generate new event end logging 1.3) If not BEGIN|END we are facing a different language and we don’t now which language! If parsing is True, set parsing=False and log debug 2) Not ‘****’ so we are parsing a line 2.1) If parsing = True, try to parse line and generate event 2.2) If parsing = False, skip until next good header is found

plaso.parsers.text_plugins.xchatscrollback module

Text parser plugin for XChat scrollback log files.

Information updated 06 September 2013.

Besides the logging capability, the XChat IRC client has the option to record the text for opened tabs. So, when rejoining a particular channel and/or a particular conversation, XChat will display the last messages exchanged. This artifact could be present, if not disabled, even if normal logging is disabled.

From the XChat FAQ (http://xchat.org/faq):

Q: ‘How do I keep text from previous sessions from being displayed when I join a channel?’ R: ‘Starting in XChat 2.8.4, XChat implemented the Scrollback feature which displays text from the last time you had a particular tab open. To disable this setting for all channels, Go to Settings -> Preferences -> Logging and uncheck Display scrollback from previous session. In XChat 2.8.6, XChat implemented both Per Channel Logging, and Per Channel Scrollbacks. If you are on 2.8.6 or newer, you can disable loading scrollback for just one particular tab name by right clicking on the tab name, selecting Settings, and then unchecking Reload scrollback’

The log file format differs from logging format, but it’s quite simple ‘T 1232315916 Python interface unloaded’ <T><space><decimal timestamp><space><text><n>

The time reported in the log is the number of seconds since January 1, 1970 00:00:00 UTC (from source code, time(0)). The <text> part could contain some ‘decorators’ (bold, underline, colors indication, etc.), so the parser should strip those control fields.
