Modus OperandiQualification of Statistics

The statistics and information presented here are based on data collected since November 1998

Attrition began actively mirroring defaced sites in January 1999

Mirrors on the attrition site date back to 1995 Data before January ‘99 is believed to be accurate

but is not 100% confirmed

Copyright 2000. attrition.org Staff

The “Root” of the ProblemHow are These Sites Being Defaced?

Unix:– Remote buffer overflows– Sniffer / trusted path attacks– Poorly-coded CGI’s

Windows NT:– RDS / MSADC– IISHack– MS Front Page misconfigurations– Other misc. CGI/Web exploits

Copyright 2000. attrition.org Staff

DefacementsSpeculation: Why are More NT Boxes Defaced?

Compare the knowledge required to navigate the hacked system: NT : Must know basic DOS Commands.

– echo "i 0wn j00" >> c:\inetpub\index.html

Unix : Must know basic Unix commands – In many cases defacers lack the common skill to even

find the main web page on a system:– find / -type f -name index.html –print– vi /path/to/index.html (wait vi is too hard to use)

Copyright 2000. attrition.org Staff

Why Me?Why Are These Sites Being Defaced?

Tagging, electronic graffiti One-upmanship - who can hit the biggest site The ‘gov/mil’ phenomenon Delusions that what they are doing is impressive

or cool It's trendy - like baggy pants, it just won't go

away. “Hacktivism” (95% convenient excuse)

The Fine Art of MirroringThe Steps

Mail comes in (hacked@attrition.org) Goes to six people on attrition (and

mirrored off site) Staff verifies the defacement (lynx,

Netscape, etc) Run a custom mirror utility 'aget'

Copyright 2000. attrition.org Staff

The Fine Art of MirroringWhat aget Does

aget Version 4.5 - 866 lines of shell script– check to see if it has been mirrored, avoid duplication– use Netcraft (www.netcraft.com/whats/), NMAP

(www.insecure.org), and lynx to verify the Operating System of the defaced site

– If NMAP OS fingerprint is unknown, mail it to Fyodor– Do a NIC lookup based on the country/TLD– Take traceroute to record upstream provider(s)– Check to see if previously defaced– Check for hidden comments in HTML, DOS signature, etc.

Copyright 2000. attrition.org Staff

The Fine Art of MirroringWhat aget Does (Continued)

– Mail CERT based on country, mail NIPC (heh)– Mail NIC contacts– Mail attrition defaced* mail lists

http://www.attrition.org/security/lists.html– Form letter clearly explaining this is a third party

notification of a security incident on the remote machine – this is just a warning that a site has been defaced, no other information is given

Copyright 2000. attrition.org Staff

Stop Hacking My %^&&* Box!"Defaced Site Administrative Response"

80 – 90%– Friendly, appreciative, asking us for help,

thanking for notification 10 – 20%

– Hostile responses, threats, insults, blame us

Copyright 2000. attrition.org Staff

Stop Hacking My %^&&* Box!Responses

CERT– Recent addition. CERT originally asked to be

removed from notification utility– When challenged on why they exist in the first

place, they agreed to receive notifications

Copyright 2000. attrition.org Staff

Stop Hacking My %^&&* Box!Responses

NIPC– Forwarded notifications on to “the appropriate

people” approximately 20% of the time – some replies state they do not fall under infrastructure threats

– No response for other 80% of notifications

Copyright 2000. attrition.org Staff

Feds UsFederal Agency / Law Enforcement Mirror Utilization

FBI Connecticut Office –– Issued a single 2703(d) subpoena requesting

information on ‘flipz’ and ‘fuqraq’– Attrition Responded and charged $16.00 for

administrative fees– $16.00 is the extent of income from federal

agencies in all of attrition’s history

Copyright 2000. attrition.org Staff

Feds UsFederal Agency / Law Enforcement Mirror Utilization

FBI Mirror Printouts – – Several raid victims have verified that printouts

from the attrition.org mirror were used during those raids

– “Did you hack this site?”

Copyright 2000. attrition.org Staff

Forensics and Mirrors(Not Profiling)

Most defacements are sloppy Leave a nice forensics trail Many patterns in defacement activity

– Easy to match one person operating under different names

– Indications groups/individuals talk before choosing targets (wave of .edu, wave of .br, wave of...)

Copyright 2000. attrition.org Staff

Linking(Public)

Obvious signs – signatures (graphics or text)

Broken Image – pathed to local drive where HTML was created - few

geniuses pathed to c:\microsoft\office\john\doe\ or similar paths that included their real name

Meta tags – Generators, meta names, and more

Greets, misspellings, language, more

Copyright 2000. attrition.org Staff

Linking(Private)

Mail to us is more candid, more verbose Defacers use Hotmail and other freemail sites w/

X-Originating-IP– (grep, quote how many times we see x-originating)– (uniq, how many unique x-originating IPs have we

seen) In some mail the defacer takes credit

– Other times a 'friend' is reporting the hack– Occasionally arbitrary third party reports it (usually on

high profile, high traffic sites).

Copyright 2000. attrition.org Staff

LinkingAnalysis

Looking at all of the above, it is trivial to link different names and group members to each other

Several defacers change name and style for a variety of reasons– A quick check at the forensics/footprints of

their work will reveal a substantial amount

Copyright 2000. attrition.org Staff

Mail Woes

Roughly 33% of mail to hacked@ are false reports Sites are not defaced, do not answer, or show no

signs of intrusions Infrequently, we receive mail of a defacement

before it happens– Typically a minute or less before defacement. Either

way, it obligates us and potentially makes us liable if we do not report the crime before it occurs

Copyright 2000. attrition.org Staff

Blame Us(Everyone Else Does)

We are often accused of encouraging defacements– This is far from the truth

Odds are we have berated and insulted most defacers for their activities - we've questioned them, encouraged them to STOP, etc.

We are not the only mirror. If we close up shop, the other mirrors will pick up our role. This isn't a good idea because we do it better

Copyright 2000. attrition.org Staff

Disclaimer(Of Course)

Conclusions based on the mirror or statistics must be looked at carefully:

Example: Saying "defacements are increasing“ – Yes. there are more defacements today than yesterday in

general – No. roughly the same percentage compared to servers

deployed (?) Example: Saying "XX OS is more secure“

– No. it is likely the OS has not been audited/tested as much as many other OS’s. You must factor if the OS is open source, how long it has been deployed, etc.

Copyright 2000. attrition.org Staff

Why Our Mirror is Better(The Fine Art of Shameless Self Promotion)

All of our information is public (and free) We notify sites of the intrusions as we learn about

them We provide mail lists to keep you informed of

defacements We collect more information about the site We provide breakouts by group, TLD,

organization We provide comprehensive statistics

Holiday Attacks

After selecting 11 holidays per year, we found that while the average was greater than for non-holidays, the holiday average was not significantly different from the non-holiday average, though there were two holidays that when examined individually were significantly greater than non-holidays: new years eve, 1999 and July 4th, 2000.

Defacement activity is not statistically different on holidays than non-holidays

Copyright 2000. attrition.org Staff

The Future

Faster updates of the main mirror page with defacements in real-time

The introduction of dynamically generated pages via user-defined queries against our defacement database(s)

Never before seen on attrition.org, user interaction with actual pages

With the introduction of the SQL database(s), more breakouts pertaining to each defacement mirrored
