osquery queries

context

dit document geeft een overzicht van enkele nuttige queries

gebruikers

gebruikers en hun groepen

SELECT usr.username, usr.uid, grp.groupname,grp.gid from users AS usr
LEFT JOIN user_groups AS usrgrp ON usr.uid = usrgrp.uid 
JOIN groups AS grp ON grp.gid = usrgrp.gid
ORDER BY usr.username;

processen

processen, pid, path en parent

SELECT datetime(p.start_time,'unixepoch','localtime') AS 'START TIME', 
p.pid AS PID,p.name AS PROCESSNAME, p.path AS PATH, 
p.parent AS PPID, p2.name AS 'PROCESSNAME PARENT' FROM processes p 
JOIN processes p2 ON p.parent = p2.pid 
ORDER BY p.start_time;

processen met hash

SELECT p.pid,p.name,u.username,p.path,h.sha1 FROM processes p 
JOIN hash h ON p.path = h.path 
GROUP BY h.sha1 
ORDER BY p.pid ASC;

Note: GROUP BY zal alle processen met eenzelfde hash samenvoegen.
Je ziet dus niet alle processen, enkel die met unieke hash

processen met hash en user

SELECT p.pid,p.name,u.username,p.path,h.sha1 FROM processes p 
JOIN hash h ON p.path = h.path 
JOIN users u ON u.uid = p.uid 
GROUP BY h.sha1 
ORDER BY p.pid ASC;

boot time

SELECT p.pid AS PID, p.parent AS PPID, p.name AS PROCESSNAME, 
p.path AS PATH, datetime (start_time, 'unixepoch','localtime') AS STARTTIME FROM processes p 
ORDER BY p.start_time ASC LIMIT 1;

laatste 10 actieve processen

SELECT p.pid AS PID, p.parent AS PPID, p.name AS PROCESSNAME, 
p.path AS PATH, datetime (start_time, 'unixepoch','localtime') AS STARTTIME FROM processes p 
ORDER BY p.start_time DESC LIMIT 10;

zoeken op procesnaam (firefox, in dit geval)

SELECT proc.pid, proc.name, usr.username, proc.path, proc.parent, proc2.name FROM processes AS proc 
JOIN processes AS proc2 ON proc.parent = proc2.pid 
JOIN users AS usr ON proc.uid = usr.uid 
WHERE proc.name like '%firefox%';
ORDER BY proc.pid;

hashing

SELECT path, sha1 from hash 
WHERE path = 'padNaarBestand';

voorbeeld:

SELECT path, sha1 from hash where path IN ('C:\windows\system32\ping.exe', 'C:\windows\system32\cmd.exe');

file

timestamps

SELECT path, datetime(atime, 'unixepoch','localtime') AS 'Acces time', 
datetime(mtime, 'unixepoch','localtime') AS 'Modified time',
datetime(btime, 'unixepoch','localtime') AS 'Created time' from file 
WHERE path = 'padNaarBestand';

voorbeeld:

SELECT path, datetime(atime, 'unixepoch','localtime') AS 'Acces time', 
datetime(mtime, 'unixepoch','localtime') AS 'Modified time',
datetime(btime, 'unixepoch','localtime') AS 'Created time' from file 
WHERE path is 'C:\Windows\System32\winevt\Logs\system.evtx';

alle bestandseigenschappen

.mode line
SELECT * from file 
WHERE path = 'padNaarBestand';

voorbeeld:

SELECT * from file 
WHERE path = 'C:\windows\system32\cmd.exe';

autorun

met target path (in geval van lnk-files)

SELECT su.name, su.path, su.args, su.username, sc.local_path, hash.md5 from startup_items AS su
JOIN hash AS hash ON hash.path = su.path 
LEFT JOIN shortcut_files AS sc ON sc.path = su.path
WHERE su.path not like '%desktop.ini%';

timestamp

 datetime(start_time, 'unixepoch','localtime') AS start_time 

netwerk verbindingen

met sha1 van process

SELECT p.pid, p.name, p.path, h.sha1, os.local_address, os.local_port, os.remote_address, os.remote_port, datetime(start_time,'unixepoch','localtime') FROM processes p 
JOIN process_open_sockets os ON p.pid = os.pid 
LEFT JOIN hash h ON h.path = p.path WHERE os.state = 'ESTABLISHED' AND os.remote_address NOT LIKE '127.0.0.1' 
GROUP BY h.sha1;
