Study Notes
Public Source-Code Repositories
- Public source-code repositories facilitate code sharing and collaboration, accelerating development.
- Popular repositories include GitHub, Bitbucket, and SourceForge.
- GitHub supports teams regardless of location, is free for basic users, and has reasonable costs for teams and enterprise users.
- Bitbucket allows inline comments, a secure workflow, and is free for small teams, with fees for larger groups.
- SourceForge is free for everyone and offers discussion forums and issue tracking.
Developer Workflow in Repositories
- Developers typically work on portions of source code and commit changes to the repository only when satisfied.
- A maintainer or project leader evaluates submitted changes and merges approved code into the main repository.
- In the 515support.com example, several applications' code is stored in a public repository.
Security Risks of Public Repositories
- Developers may inadvertently include private files in public repositories.
- Code often contains hostnames, IP addresses, database servers, and configurations, exposing systems to attack.
- Employee names and information could be used in spear phishing or credential theft attacks.
- Malicious actors can modify code causing infrastructure attacks, system shutdowns, or application crashes.
- Screenshots or comments within code might contain valuable intelligence.
- Developers may expose usernames and passwords in the code.
Google Hacking (Google Dorking)
-
A technique used in PenTesting to identify potential security weaknesses by strategically using Google search operators.
-
Precise search queries are employed to limit irrelevant results.
-
Advanced Operators such as "site," "link," "filetype," "inurl," and "inanchor" are used to filter results.
-
site: Limits the search to a specific website (e.g.,
site:comptia.org report). -
link: Locates pages linking to a specific page (e.g.,
link:comptia.org report). -
filetype: Retrieves specific file types (e.g.,
filetype:pdf report). -
inurl: Filters by URL terms (e.g.,
inurl:Certification report). -
inanchor: Targets anchor text (e.g.,
inanchor:Certification report). -
Powerful search results arise from combining multiple operators in a single query, maximizing specific information retrieval (e.g.,
site:comptia.org filetype:pdf OR filetype:docx inanchor:Certification report). -
Search engines like Google offer similar functions.
-
Archived versions of web pages are also crucial for information retrieval.
