Black SEO (or Negative SEO): sabotage techniques aiming to reduce
a web site's ranking in search engine results


Introduction

SEO – Search Engine Optimisation
Search engine optimisation (SEO) is the process of improving the
volume and quality of traffic to a web site from search engines via
"natural" ("organic" or "algorithmic") search results for targeted
keywords.

TOP 10 search engines results page (SERP) = SEO industry
Some SEO terms: positioning, ranking, keywords
SEO Hats:
White Hat SEO: web promotion techniques following search
engine guidelines
Black Hat SEO: web promotion techniques not following any
guidelines


Black SEO - Definition

Black SEO Security Concept Map


Security Implications 1/2

The common perception towards black SEO:
Google: “There's almost nothing a competitor can do to harm
your ranking or have your site removed from our index”
index
General Assumption: “Black SEO is only related to SEO”
Black SEO and Security:
IT Security still does not include this category of attacks
Most
M t IT Security literature does not even mention the SEO t
S it lit t d t ti th term
The potential:
Black SEO attacks do not always involve exploitation of target
vulnerabilities
50% of the OWASP Top 10 can be used to leverage black SEO
attacks
Knowledge gap between SEO hackers and WEB hackers is
reducing - Latest web spam techniques exploit XSS

Security Implications 2/2

Black SEO security considerations:
Three elements in the security model:

Search engine internal processes are not disclosed
Real unknown variable in the black SEO security model
Black SEO attacks:
Search engines process the attack
Attack results are not direct (might be visible after 3 days, 1
( g y ,
week, 1 month or might not be processed)
Attacker needs to monitor continuously attack results
Target needs to realise if under attack

Methodology

If you know the enemy and know yourself, you need not fear the result
of a hundred battles. If you know yourself but not the enemy, for
e e y cto y gained
every victory ga ed you will also suffer a defeat. If you know
a so su e de eat o
neither the enemy nor yourself, you will succumb in every battle.

- Sun Tzu

Eliminating target resources



The neighbours target map (visual concept):

Thinking like a search engine:
A link to a page = casting a vote
p g g
Votes are related to a specific content/information
Many votes to a site indicate that the site is “authoritative” /
authoritative
“trusted” for a specific content = best value to user


Eliminating target resources:
Remove/divert links from authoritative/trusted sites to target site
Remove/divert direct incoming links to target site
/d d l k
Two main attack approaches:
Hack neighbours sites and remove links
Social engineering + direct attack
First approach not always feasible. Second approach:
Impersonate target and social engineer target resources
Motives to remove/divert link: rebranding, restructuring,
maintenance, new domain, spam links, etc.
Enforce case with new domain registered as target, XSS/SQL
injection, spam links, etc.



A possible attack scenario:

Impact:
p
Decreased quality/quantity of target neighbours
Target position and rank affected


Frontal attacks


Frontal Attacks Table

Frontal attacks classification
Scope Exploit Probability Attack Impact
Complexity of success Timeframe
Decrease: Low/Medium High/Medium Long Position/Rank
• rank decreased
• position • Reversing search • Web Spam as a • Crawling
• backlinks engines proof • Indexing
• Caching

Demonstrate: High Low/Medium Medium Target
target is: ban/penalisation
• Target vulnerable • Human review of • Tools speed
• deceitful
• Low spam reports indexing
• fraudulent quality/quantity (quantity/quality)
• spamming
p g target backlinks
• Moderate/Absent
target SEO skills

The two scopes and the techniques involved have completely
p q p y
opposite results
Attacker makes a choice depending on: available timeframe,
resources, skills and target exploitability
kill dt t l it bilit


Decreasing target positioning

Attack: Spam social bookmarks with target URL
Digg.com, Reddit.com, Onlywire.com, etc
Automatic script + social bookmarks API
lb k k
http://www.onlywire.com/api/add?url=http://targetsite&ti
tle=targetsite&comments=targetsite&tags=targetsite

Impact: Target can be banned. Target site loses links from
trusted/high PR domains

Attack: Duplicate target content in:
target site (exploit stored XSS or SQL injection)
domain with higher PR of target site (buy another site)
many sites (build network of clones)
Impact: Target penalised for duplicate content



Attack: Submit web proxy + target site to search engines
Use proxy with a higher PR and/or higher number of backlinks
than target
Use proxy that do not obfuscate target URL
http://www.zzoop.com/index.php? & http://targetsite/
http://www.zzoop.com/index.php?=&=http://targetsite/

Impact: target position may drop suddenly

Attack: Mass submissions of target to low quality web directories
Most of them are free. Low quality = n/a or PR 0
Publication can take up to 6 months. Do mass submission.
http://www.web-directories.ws
Impact: Decrease quality of neighbours. Position decreased.



Attack: Create backlinks to unused target subdomain
www.targetsite.com – 200 OK (used/promoted)
targetsite.com – 200 OK (
(not used) <- b kl k target
d) backlinks

content
Impact: Positioning affected

Attack: DoS target
Spider needs a 404 Not Found response from target
Then request removal of unavailable target pages
Impact: Target page removed from SERPS



Attack: Promote target site URL + dynamic content such as:
Session IDs
Variables with long values
bl hl l
http://targetsite/?PHPSESSIONID=a8s7d8782378273827381273821s98d&productId=a9
982938219038291832918391389218931&a2=9sa8d9as7d9a7d98sa7d8sa7d8asdsa&b2=1203
18291289381938921&login=true

Impact: positioning decreasing, pages removal or no pages caching
Attack: Promote competition of target using White Hat SEO

Impact: positioning decreased


Attack: Build fake content based on target keywords
Turn everything from the target keywords into education
content which provides real value to end user

Conclusions

And remember
remember...
Q: What can I do if I'm afraid my competitor is harming my
ranking in Google?
Google: There's almost nothing a competitor can do to harm your
ranking or have your site removed from our index. If you're
concerned about another site linking to yours, we suggest
contacting the webmaster of the site in question. Google aggregates
a d o ga es o at o published on the eb; e don't control
and organizes information pub s ed o t e web; we do t co t o
the content of these pages.
