[1301.20 --> 1301.92] or maybe they did
[1301.92 --> 1302.64] and then they wiped it
[1302.64 --> 1303.44] so there's no track.
[1303.52 --> 1304.14] So maybe they did
[1304.14 --> 1305.08] do something nefarious.
[1305.26 --> 1306.08] I have no idea.
[1306.08 --> 1306.50] I mean,
[1306.52 --> 1307.04] if your password
[1307.04 --> 1307.56] is 22,
[1307.80 --> 1310.22] maybe old Alex
[1310.22 --> 1311.14] didn't know how to check.
[1313.06 --> 1313.42] Yeah.
[1313.52 --> 1313.72] I mean,
[1313.74 --> 1314.36] back in the day,
[1314.50 --> 1316.54] that was something
[1316.54 --> 1317.90] you just didn't really think of
[1317.90 --> 1318.74] way back in the day.
[1318.82 --> 1319.32] Things were just
[1319.32 --> 1319.92] on the internet.
[1320.10 --> 1322.14] When I first got exposure
[1322.14 --> 1324.12] to TCP IP networking,
[1324.68 --> 1325.82] everything had a public
[1325.82 --> 1326.56] internet address
[1326.56 --> 1327.32] on the network.
[1327.72 --> 1328.84] And it wasn't until
[1328.84 --> 1330.18] sometime later
[1330.18 --> 1331.36] that we had firewalls
[1331.36 --> 1332.12] and NATs.
[1332.20 --> 1333.04] And so for a short period
[1333.04 --> 1333.30] of time,
[1333.34 --> 1333.90] you could basically
[1333.90 --> 1334.80] connect to everything.
[1336.30 --> 1337.58] There was some crazy stuff
[1337.58 --> 1338.32] we did back then.
[1338.88 --> 1339.58] I didn't want to put you guys
[1339.58 --> 1339.98] on the spot,
[1340.08 --> 1341.00] but I would be curious
[1341.00 --> 1343.14] about how to go about
[1343.14 --> 1344.30] detecting some of this stuff,
[1344.54 --> 1344.76] you know,
[1344.78 --> 1345.62] even from a most
[1345.62 --> 1347.00] very basic level.
[1347.68 --> 1348.00] Hmm.
[1348.18 --> 1348.42] Well,
[1348.48 --> 1348.82] I mean,
[1348.82 --> 1349.24] I'm sure Alex,
[1349.26 --> 1350.10] you probably have a few ideas.
[1350.26 --> 1351.18] My first couple
[1351.18 --> 1351.78] that come to mind
[1351.78 --> 1353.40] would be know what processes
[1353.40 --> 1353.94] should be writing
[1353.94 --> 1354.58] on your box,
[1354.72 --> 1355.60] check your logs.
[1355.96 --> 1356.46] I mean,
[1356.48 --> 1358.16] almost every single time
[1358.16 --> 1359.70] that a client machine
[1359.70 --> 1360.10] or something
[1360.10 --> 1361.56] was behaving poorly,
[1362.24 --> 1363.18] I could almost immediately
[1363.18 --> 1364.14] just suss it out
[1364.14 --> 1364.84] by running top.
[1365.10 --> 1365.54] I mean,
[1365.58 --> 1365.90] really,
[1366.18 --> 1366.40] because,
[1366.54 --> 1366.64] you know,
[1366.70 --> 1367.52] you know what that machine
[1367.52 --> 1368.40] is supposed to be doing.
[1368.60 --> 1369.58] And if there's some process
[1369.58 --> 1370.50] going crazy on there
[1370.50 --> 1371.34] that has nothing to do
[1371.34 --> 1372.28] with the responsibilities
[1372.28 --> 1373.18] of that box,
[1373.28 --> 1374.38] you got a pretty good idea
[1374.38 --> 1374.98] of what it is.
[1375.66 --> 1376.56] And then you look
[1376.56 --> 1377.18] at your logs,
[1377.26 --> 1377.42] right?
[1377.42 --> 1378.96] You look at the active users
[1378.96 --> 1380.42] that are logged onto the system
[1380.42 --> 1381.96] and you kind of start
[1381.96 --> 1382.62] tracing it back.
[1382.70 --> 1383.22] Usually you'll look
[1383.22 --> 1383.80] at the process
[1383.80 --> 1384.32] and there'll be like
[1384.32 --> 1386.08] some weird path
[1386.08 --> 1386.64] or URL
[1386.64 --> 1387.86] for a process
[1387.86 --> 1388.72] that looks normal,
[1388.82 --> 1389.92] but it's in the wrong place
[1389.92 --> 1390.68] or it's being run
[1390.68 --> 1391.56] by the wrong user
[1391.56 --> 1392.92] and you kind of track
[1392.92 --> 1393.54] it back from there.
[1394.40 --> 1395.44] Depends where
[1395.44 --> 1396.98] your expertise lies.
[1397.48 --> 1399.12] If you're a networking guy,
[1399.38 --> 1400.24] you could use something
[1400.24 --> 1401.32] like Snort,
[1401.84 --> 1402.64] which is essentially
[1402.64 --> 1404.52] a packet filter
