When Standard Searches Stop, Specialized Intelligence Begins
RecOsint Research & Content Division | 9 min read
The Email That Unraveled Everything
An attorney called with a single piece of information: an email address found in encrypted communications during a fraud investigation.
nighthawk_trading@protonmail.com
It appeared in discussions about offshore accounts and asset concealment. Standard searches returned nothing. ProtonMail doesn’t disclose user information. The pseudonym “nighthawk” was too generic to trace. Dead end.
Or so it seemed.
We took that email address and began pulling threads. Seventy-two hours later, we had:
The complete picture:
- 14 online accounts registered to that email across forums and marketplaces
- A username pattern (“nighthawk” + variants) appearing on 23 additional platforms
- A phone number linked through a 2019 data breach connecting to social media profiles
- Historical website registrations showing business ventures in three countries
- Underground forum posts discussing the exact asset concealment strategies mentioned in the case
- A real identity, physical address, and network of associated individuals
One email address became a comprehensive intelligence package revealing identity, methods, associates, and a complete digital footprint.
This is what specialized OSINT research does. It answers questions conventional searches can’t touch.
After conducting over 900 custom intelligence investigations—from missing persons to corporate fraud, cyber threat intelligence to due diligence—we’ve learned that most critical intelligence exists somewhere online. The challenge isn’t whether information exists. The challenge is knowing where to look and how to connect it.
At RecOsint Intelligence Services, OSINT research capabilities integrate with social media intelligence, metadata forensics, vulnerability assessment, and corporate due diligence—enabling investigations that combine technical analysis with behavioral intelligence and business context.
When Google Stops Working
You’ve searched Google. Checked LinkedIn. Tried Facebook. But some questions require going deeper—to the 96% of the internet that standard search engines don’t index.
Questions we hear every week:
“Who actually owns this email address?”
Google shows nothing. The email provider won’t disclose user information. But that address has been used to register for accounts, post in forums, appear in data breaches, sign up for services. Each use leaves traces we can follow.
“Where did this person go?”
Social media inactive for months. Phone disconnected. Standard skip tracing hits dead ends. But digital footprints don’t disappear—new usernames emerge, gaming accounts stay active, forum posts continue, app check-ins reveal locations.
“Has our company’s data been breached?”
Your IT team monitors known incidents, but credential dumps circulate on dark web forums months before public disclosure. Employee passwords appear in paste sites. Domain-specific breaches get discussed in underground communities well before hitting the news.
“What did their website say before they deleted everything?”
The Internet Archive has some snapshots, but they’re incomplete. You need deleted pages, removed content, previous business claims, old contact information—evidence that’s been scrubbed from current online presence.
“Who’s behind this anonymous online account?”
Username: TechInvestor2023. Location: Unknown. Real name: Hidden. But usernames get reused across platforms. People maintain behavioral patterns. Cross-platform activity creates connections. Technical artifacts leave trails.
“What’s being said about us in places Google doesn’t reach?”
Not on Twitter. Not in news articles. But in closed forums, dark web marketplaces, encrypted chat logs, paste site dumps—discussions, threats, stolen data, reputation damage occurring in spaces standard monitoring misses.
These aren’t hypothetical. They’re real investigations our team handles weekly.
Standard search engines index about 4% of the internet. The other 96% requires different tools, methods, and expertise.
Email Intelligence: What One Address Reveals
The Thread That Connects Everything
Most people don’t realize how exposed their email addresses are. You use it once to register for a service in 2015. That service gets breached in 2018. Your email appears in the leaked database. Now it’s searchable, traceable, and connectable to dozens of other accounts.
What email intelligence uncovers:
Account Registrations:
Services you signed up for years ago. Some forgotten. Some you thought were private. Many platforms allow username enumeration—we can determine if an email is registered without needing to log in.
Data Breach Appearances:
Which breaches exposed this email? What other data was compromised—passwords, security questions, phone numbers, personal information? Sometimes passwords are hashed; often they’ve been cracked and published in plaintext.
Associated Usernames:
People typically use the same username across multiple platforms. If we find the username linked to your email on one site, we can track that username across hundreds of others.
Phone Number Connections:
Many breaches include phone numbers. Some platforms link email to phone for account recovery. These connections let us pivot from email intelligence to phone intelligence.
Real Identity Correlation:
Email addresses often contain name fragments. When combined with breach data, social media searches, and account activity patterns, we can establish real-world identities behind pseudonymous addresses.
Real Investigation: The Vendor Who Didn’t Exist
The Case (2024):
A company was evaluating a technology vendor for a critical project. The vendor presented professional credentials, an impressive client list, and a polished website. Standard background checks found nothing concerning—proper business registration, clean criminal record, seemingly legitimate operation.
The client requested one thing: verify the CEO’s background claims.
Our starting point: One business email address from the website contact form.
What email intelligence revealed:
Step 1: Breach Database Analysis
- Email appeared in three separate data breaches (2018, 2020, 2022)
- Associated with six different usernames across the breached platforms
- One username stood out: “fastbuck_investor”
Step 2: Username Investigation
- “fastbuck_investor” appeared on 14 platforms
- Forum posts from 2017-2019 discussing “quick flip” business schemes and aggressive sales tactics
- Online marketplace reviews showed a pattern of disputed transactions and customer complaints
- Social media posts contradicted claimed industry experience and credentials
Step 3: Domain Registration History
- CEO’s email was the admin contact for eight previous domains
- Five domains were associated with failed businesses (archived complaints still accessible)
- Two domains had been flagged for fraudulent activity by consumer protection agencies
- Clear pattern: launch venture, collect payments, disappear within 8-10 months
Step 4: Timeline Reconstruction
- Current company was only six months old (CEO claimed “10-year track record”)
- Previous ventures averaged 8-month lifespan before dissolution
- Consistent pattern of creating new business entities after each failure
Outcome:
Company declined the vendor relationship. Six months later, the vendor’s business collapsed with multiple client lawsuits for undelivered services.
One email address revealed a decade-long pattern of business fraud that saved our client from significant financial loss.
Username Investigation: Connecting Digital Identities
How Username Patterns Reveal Everything
Here’s what most people don’t think about: username consistency.
You create “TechGuru_Mike” for a forum in 2012. You like it. You use it again on Reddit in 2015. Then Twitter in 2018. Gaming platforms. GitHub. Stack Overflow. Instagram variations like “TechGuruMike” or “Mike_TechGuru.”
Each platform reveals different puzzle pieces:
- Forums: Long-term posting history, opinions, technical knowledge, interests
- GitHub: Real names in code commits, technical skills demonstrated in repositories
- Gaming platforms: Gaming habits, purchase patterns, social connections, competitive rankings
- Social media: Photos, locations, relationships, family information, real identity
- Marketplaces: Transaction history, seller reputation, buyer feedback, shipping addresses
One username becomes a thread connecting seemingly separate identities.
Our cross-platform correlation methods:
Username Enumeration:
We systematically check 300+ platforms for username existence. Tools like Sherlock, Maigret, and WhatsMyName automate initial discovery, but manual verification confirms genuine matches versus coincidental username reuse by unrelated people.
Behavioral Analysis:
Do posting patterns, language style, technical expertise, and interests align across platforms? Inconsistencies suggest different people using the same username. Consistency confirms a single identity.
Temporal Correlation:
Account creation dates, activity periods, posting frequency tell a story. If “TechGuru_Mike” is active on Platform A from 2015-2018, then appears on Platform B in 2018 right after Platform A activity stops, that’s temporal correlation suggesting the same person migrating platforms.
Biographical Consistency:
Location mentions, age ranges, occupation references, life events discussed. When someone mentions “moved to Seattle” on one platform and another account starts posting Seattle-specific content simultaneously, that’s biographical correlation.
Technical Artifacts:
Profile photos (reverse image search connects accounts), email addresses (when partially visible), linked social accounts (Twitter connected to Instagram), timezone patterns in posting history—all create connections.
Real Investigation: The Anonymous Whistleblower
The Case (2023):
A company received anonymous threats from username “CorporateWatchdog_2023” on an industry forum. The threats included claims of possessing confidential internal documents and intentions to leak them publicly unless demands were met.
The forum allowed anonymous posting. No email addresses visible. No registration information accessible. Just a username and increasingly aggressive posts.
Our username investigation:
Step 1: Pattern Analysis
- “CorporateWatchdog_2023” was newly created (same week as threats)
- The “_2023” suffix suggested this might be a variation of an existing username
- We searched for “CorporateWatchdog” across 300+ platforms
Step 2: Cross-Platform Discovery
- “CorporateWatchdog” existed on six other platforms with different contexts
- Creation dates ranged from 2019-2021 (all older than the threatening account)
- One platform showed a partially visible email:
j***@pm***il.com
Step 3: Email Intelligence Pivot
- Searched breach databases for patterns matching
j***@pm***il.com - Found candidate email
jsmith@pmmail.comin a 2020 data breach - That email was associated with username “jwatchdog” on the breached platform
Step 4: Username Expansion
- Searched “jwatchdog” variants across all platforms
- Found “jwatchdog” on a professional networking site with limited information
- Profile showed real name: John Smith (common, needed more specifics)
Step 5: Biographical Correlation
- Forum posts by “CorporateWatchdog” mentioned attending specific industry conferences
- “jwatchdog” profile showed attendance at the same conferences
- Geographic references in posts matched the company’s headquarters city
- Technical knowledge aligned with a specific department’s expertise
Step 6: Social Media Connection
- Located LinkedIn profile matching the industry background and conference attendance
- Found associated Twitter account using a username variation
- Cross-referenced photos that matched across multiple platforms
- Employment history showed this person previously worked at the client company
Step 7: Timeline Analysis
- Employment ended six months before threats began
- Post-employment activity on other platforms showed increasing hostility toward former employer
- Threatened document leak timing aligned with access windows from previous role
Outcome:
Legal counsel contacted the identified individual. Threats immediately ceased. No documents were leaked. Civil settlement reached.
One username became a verified identity through systematic cross-platform correlation and behavioral analysis.
Phone Number Intelligence: The Overlooked Identifier
What Phone Numbers Actually Tell Us
People guard their email addresses carefully. They’re cautious about usernames. But phone numbers? They share them casually—WhatsApp groups, online marketplace listings, forum signatures, business cards, public directories.
What phone intelligence reveals:
Carrier & Technical Details:
- Service provider identification (major carrier vs. VOIP)
- Number type (mobile, landline, VoIP service)
- Geographic registration area
- Porting history (when numbers transfer between carriers)
Online Account Associations:
- Social media accounts using the number for registration or account recovery
- Messaging apps tied to numbers (WhatsApp, Telegram, Signal profiles)
- Marketplace accounts (eBay, Facebook Marketplace, local classifieds)
- Service accounts requiring phone verification (banking apps, delivery services)
Data Breach Appearances:
- Breaches exposing phone numbers alongside emails and passwords
- Account credentials associated with specific phone numbers
- Two-factor authentication data in leaked databases
Public Records & Connections:
- Business registrations listing contact numbers
- Historical ownership records from directory services
- Associated addresses and names from public databases
- Connections to other phone numbers (family members, business partners)
Real Investigation: The Rental Fraud Ring
The Case (2024):
Multiple victims reported fraudulent rental listings. A scammer posted attractive apartments at below-market rates, collected security deposits, then disappeared. Payments went to prepaid debit cards or cryptocurrency wallets. The only consistent identifier: a phone number used for “landlord” communications.
Our phone intelligence investigation:
Step 1: Number Analysis
- Identified as VOIP number (red flag—legitimate property managers rarely use VOIP for business)
- No carrier registration area (consistent with internet-based phone services)
- Number active only three weeks (new number for each scheme cycle)
Step 2: Account Association Search
- WhatsApp account active (profile photo was generic stock image)
- Telegram account using same number
- Notably absent: No Facebook, Twitter, LinkedIn presence (unusual for legitimate business contact)
Step 3: Breach Database Search
- Number appeared in a 2022 marketplace breach
- Associated email:
rental_properties_usa@gmail.com - Same breach data connected this email to a second phone number
Step 4: Secondary Phone Investigation
- Second number was a mobile carrier (not VOIP)
- Registered to a specific geographic area in Florida
- Social media accounts linked to this mobile number
Step 5: Social Media Deep Dive
- Facebook profile associated with the mobile number
- Profile name matched a person named in rental fraud complaints from 2020 in another state
- Location information matched the mobile number’s registration area
- Profile showed previous business ventures with similar fraud patterns
While OSINT research identifies accounts and usernames, our specialized SOCMINT capabilities go deeper—conducting cross-platform behavioral analysis, fake profile detection, network relationship mapping, and geolocation intelligence extraction from public social media activity.
Step 6: Pattern Analysis
- Historical fraud complaints used different VOIP numbers (changed frequently)
- The same mobile number appeared in contact records of victims from previous schemes
- Pattern revealed: Scammer rotates VOIP numbers but keeps same mobile backup number
Outcome:
Evidence package provided to law enforcement across multiple jurisdictions. Pattern of fraud documented spanning three years and seven states. Scammer identified through the persistent mobile number and charged with multiple counts of wire fraud.
One phone number—overlooked as disposable—became the key that connected years of fraudulent activity.
Breach Data Analysis: Understanding Your Exposure
The Data That’s Already Out There
Most organizations ask: “Have we been breached?”
Better question: “What data about us is already circulating in breach databases and underground forums?”
Credentials leak constantly—not always through direct company breaches. Third-party service compromises affect organizations indirectly. Employees reuse passwords across personal and professional accounts. Contractors use company emails for personal services. Partners with weak security create exposure.
What breach analysis reveals:
Credential Exposure Assessment:
- Which company email addresses appear in breach databases
- Associated passwords (sometimes plaintext, sometimes hashed but crackable)
- Password patterns revealing organizational reuse behavior
- Security question answers that enable account takeover
Organizational Exposure Mapping:
- How many employees have been affected by breaches
- Which departments show highest exposure rates
- Third-party service breaches affecting company domains
- Historical timeline of credential exposure
Risk Severity Analysis:
- Current password status (are breached passwords still active?)
- Privileged account exposure requiring immediate attention
- Password reuse patterns across multiple breaches (same password appearing in multiple leaks)
- Time elapsed since breach (older breaches may have inactive credentials)
Actionable Remediation:
- Active credentials requiring immediate forced resets
- Compromised accounts with elevated privileges
- Departments requiring security awareness training
- Third-party vendor access requiring security review
Real Investigation: The Predictable Password Pattern
The Case (2024):
A company suspected executive account compromise. Their CFO’s email credentials were apparently used to authorize fraudulent wire transfers totaling $380,000. Security investigation found no evidence of phishing. No malware detected. Strong password policy enforced. Two-factor authentication enabled on all executive accounts.
How did attackers obtain credentials?
Our breach analysis investigation:
Step 1: Corporate Domain Search
- Scanned breach databases for all company domain emails
- Found 47 employee email addresses in various breaches spanning 2018-2023
- CFO’s corporate email: Not found in any breaches
Step 2: Personal Email Investigation
- Located CFO’s personal email address through LinkedIn and public records
- Personal email appeared in 2019 LinkedIn breach
- Exposed password:
Finance2019! - Pattern visible: [Word][Year][Exclamation mark]
Step 3: Password Pattern Analysis
- CFO likely used similar pattern for corporate passwords
- If pattern followed year updates:
Finance2020!,Finance2021!,Finance2022! - Current year pattern would be:
Finance2024!
Step 4: Attack Vector Reconstruction
- Attackers obtained personal email/password from 2019 LinkedIn breach
- Recognized the year-based password pattern
- Extrapolated pattern to current year
- Gained corporate account access using predicted password:
Finance2024!
Step 5: Verification
- CFO confirmed password pattern matched prediction
- Pattern had been used consistently since 2017 (before 2019 breach)
- Two-factor authentication bypass: Attackers used session token from company VPN connection
Outcome:
Password policy completely revised. Pattern-based passwords prohibited. Biometric authentication implemented for financial transactions. Additional wire transfer verification procedures established. Security awareness training focused on password pattern vulnerabilities.
A 2019 personal account breach enabled a 2024 corporate compromise—through password pattern recognition.
Dark Web Research: Beyond the Hollywood Myths
What Dark Web Monitoring Actually Involves
Movies portray “hackers” entering mysterious dark web marketplaces filled with exotic illegal goods. Reality is far different—and far more useful for intelligence purposes.
What we actually monitor:
Credential & Access Markets:
- Stolen database sales and credential dumps
- Compromised corporate account access
- Privileged account credentials for sale
- Initial access broker listings
Threat Intelligence Sources:
- Ransomware group communications and leak sites
- Attack planning discussions in closed forums
- Exploit development and vulnerability sharing
- Malware distribution networks and C2 infrastructure
Brand & Reputation Monitoring:
- Unauthorized use of company names and trademarks
- Counterfeit product sales and distribution
- Corporate impersonation attempts
- Confidential data leaks and document dumps
Underground Technical Forums:
- Industry-specific discussion boards
- Vulnerability disclosures before public release
- Adversary tactics, techniques, and procedures (TTPs)
- Zero-day exploit discussions
The reality: Most valuable intelligence isn’t “mysterious” or dramatic. It’s systematic monitoring of known platforms where threat actors operate semi-openly. No Hollywood drama. Just persistent observation and intelligence collection.
Real Investigation: The Ransomware Early Warning
The Case (2023):
A manufacturing company engaged us for ongoing threat intelligence monitoring after a wave of ransomware attacks hit their industry sector.
Dark web monitoring timeline:
Week 1 Discovery:
- Forum post seeking “access brokers” specifically for manufacturing sector
- Particular interest in companies matching our client’s technology stack
- Offer to purchase initial access credentials or vulnerability information
Week 3 Marketplace Listing:
- Private marketplace listing appeared offering “manufacturing company network access”
- Description matched client’s industry segment, approximate company size, geographic region
- Access type indicated compromised VPN credentials providing remote network access
- Asking price: $15,000 (typical for mid-sized enterprise access)
Week 4 Detailed Information:
- Seller posted additional details: company size range, location region, revenue estimates
- All details consistent with our client’s profile
- Seller claimed “verified admin-level access” with proof screenshots (intentionally blurred)
- Several ransomware operators expressed interest in purchasing
Immediate Response Protocol:
- Client notified within 2 hours of discovery
- Emergency security audit initiated immediately
- All VPN access credentials reviewed and tested
- One contractor account identified as compromised (weak password, no 2FA enabled)
Resolution:
- Compromised access revoked before exploitation
- Enhanced authentication implemented across all remote access
- Contractor vetting procedures strengthened
- Ongoing monitoring continued
Outcome:
Ransomware attack prevented before initiation. Our monitoring service cost: $5,000/month. Typical ransomware demand for similar-sized companies: $500,000-$2,000,000. Attack prevention: invaluable.
Dark web monitoring provided early warning that standard security tools completely missed.
Website Historical Analysis: Digital Archaeology
Recovering What’s Been Deleted
“Can you find what their website said before they deleted it?”
This question comes up constantly in litigation, fraud investigations, and due diligence. Companies remove incriminating statements. Individuals scrub embarrassing content. Entire websites disappear.
Our historical recovery sources:
Internet Archive (Wayback Machine):
- Snapshots dating back to 1996 for popular sites
- Not comprehensive—many sites never get archived
- Robots.txt can block archiving (sites can opt out)
- Deletion requests sometimes honored (though rare)
Search Engine Caches:
- Google Cache (when available, typically 1-2 weeks old)
- Bing Cache (sometimes preserves content longer)
- Yandex Cache (Russian search engine, often retains content after others delete)
- Archive.today (manual captures by users)
Alternative Archive Sources:
- Common Crawl datasets (massive web archives for research)
- Library of Congress web preservation archives
- National archives in various countries
- Academic web preservation projects and research databases
Secondary Preservation:
- Content quoted or embedded in other websites
- Social media posts sharing text, images, or links
- Press releases redistributed on PR websites
- Web scraping databases maintained by researchers
Technical Historical Data:
- Historical WHOIS records (domain ownership changes)
- DNS history (nameserver modifications over time)
- SSL certificate history (certificates reveal server information)
- Subdomain discovery (finding forgotten subdomains)
Real Investigation: The Product Claims That Vanished
The Case (2024):
Consumer protection lawsuit against a supplement company. The company had made specific health claims about product effectiveness that triggered legal action. After litigation began, their website underwent complete revision—all aggressive claims removed, content sanitized to conservative medical language.
Plaintiffs needed evidence of the original claims. Current website showed only careful, qualified statements. Company denied ever making the disputed health claims.
Our historical reconstruction:
Step 1: Wayback Machine Analysis
- Located 37 snapshots between 2019-2023
- Early versions (2019-2020) showed aggressive, unsubstantiated health claims
- Progressive toning down of language through 2021-2022
- Most aggressive claims completely removed in March 2023 (right after legal inquiry)
Step 2: Google Cache Recovery
- Found cached versions slightly newer than Wayback snapshots
- Captured intermediate claim revisions not in Wayback
- Dated pages demonstrated evolution of claim language
Step 3: Social Media Preservation
- Facebook posts from 2021-2022 directly quoted website claims
- Instagram promotional posts showed screenshots of original website text
- Customer reviews on Facebook referenced specific health claims no longer on site
- Twitter posts from company account repeated the disputed claims
Step 4: Press Release Archives
- Company press releases from 2020 quoted product health claims verbatim
- Third-party health and wellness websites cited the claims with direct quotes and links
- Affiliate marketing sites preserved entire promotional pages with original content
Step 5: YouTube Evidence
- Product promotional videos on company’s official YouTube channel
- Videos displayed website screenshots clearly showing original health claims
- Upload dates established clear timeline of when claims were public
- Video descriptions repeated the disputed claims
Step 6: Complete Timeline Reconstruction
- 2019-2022: Aggressive, unsubstantiated health benefit claims
- 2022-Early 2023: Gradual claim softening and hedging language
- March 2023: Major website revision removing disputed claims (immediately after legal inquiry)
- Current: Conservative language with medical disclaimers only
Outcome:
Plaintiffs presented comprehensive evidence proving company originally made all disputed claims. Historical digital evidence was irrefutable. Company settled case rather than proceed to trial.
Digital archaeology recovered evidence that no longer existed on the live website—evidence critical to the case.
Research Ethics & Legal Boundaries
Where We Draw the Line
Effective intelligence work requires clear ethical and legal boundaries. Here’s exactly where we operate:
We Never:
- Hack systems or conduct unauthorized access attempts
- Purchase stolen credentials from criminals or dark web markets
- Participate in illegal marketplace transactions
- Commission data theft or unauthorized database penetration
- Impersonate individuals to gain unauthorized access
- Social engineer targets to extract confidential information
- Exceed legal research boundaries regardless of client urgency
We Always:
- Use exclusively publicly accessible information
- Leverage legitimate breach disclosure databases used by security researchers
- Monitor dark web observationally without participation in illegal activities
- Respect website terms of service and platform rules
- Maintain strict ethical standards in all investigations
- Operate within legal frameworks of applicable jurisdictions
Dark Web Research Specifically:
When investigating dark web platforms, we remain strictly observational. We monitor threat actor communications, track credential sales, identify attack planning—but we never engage in marketplace transactions, participate in criminal conspiracy, or undertake activities that would violate laws, even when pursuing legitimate intelligence objectives.
Breach Data Analysis Limits:
We analyze only publicly disclosed breach databases and information already circulating within legitimate security research communities. We never purchase stolen credentials from criminals, commission unauthorized data extraction, or participate in markets facilitating ongoing cybercrime.
Client Confidentiality:
All investigation activities, findings, and client identities remain strictly confidential. Research is conducted with operational security preventing target awareness and prohibiting third-party disclosure of investigation activities or objectives.
The Investigation Process
How Custom Research Works
Phase 1: Intelligence Requirements Definition
Initial consultation establishes exactly what you need to know and why. We define success criteria, identify acceptable research methods, establish timeline expectations, and agree on deliverable format.
Phase 2: Research Strategy Development
We design custom methodology selecting appropriate tools, databases, platforms, and investigation techniques. Strategy considers information types, target obscurity, required verification standards, legal boundaries, and resource allocation.
Phase 3: Multi-Source Information Collection
Systematic gathering from diverse sources: public databases, archived resources, specialized search engines, dark web platforms when appropriate, breach repositories, technical infrastructure queries—using specialized tools for each category.
Phase 4: Cross-Validation & Verification
Every finding verified through independent source confirmation. Technical validation confirms accuracy. Temporal consistency checks identify anomalies. Logical correlation analysis eliminates false positives and ensures reliability.
Phase 5: Pattern Analysis & Connection Mapping
We synthesize disparate findings to identify relationships, behavioral patterns, timeline sequences, and hidden connections. Raw data transforms into meaningful intelligence supporting your decision requirements.
Phase 6: Intelligence Documentation
Comprehensive reporting with executive summary, detailed findings, complete methodology disclosure, supporting evidence, confidence level assessments, and actionable recommendations directly addressing your original intelligence questions.
Timeline varies by complexity:
Simple email intelligence might take 24-48 hours. Complex investigations involving multiple identities, historical reconstruction, and dark web research typically require 1-3 weeks.
When You Need Specialized OSINT Research
Standard searches work fine—until they don’t.
When investigations hit walls. When anonymous threats emerge. When people vanish. When fraud is suspected but evidence is hidden. When data breaches go undetected. When critical information has been deleted.
That’s when specialized research provides answers.
Our team has conducted over 900 custom intelligence investigations across:
- Corporate fraud investigations and due diligence
- Missing persons cases and skip tracing
- Cyber threat intelligence and security assessments
- Litigation support and evidence recovery
- Brand protection and reputation management
- Insider threat investigations
- Cybersecurity incident response
The questions Google can’t answer require different tools, different methods, and specialized expertise.
We find the identity behind the pseudonymous email. The real person behind the anonymous username. The exposure lurking in breach databases. The claims deleted from websites. The threats discussed on dark web forums. The connections between seemingly unrelated digital identities.
When standard searches stop working, our research begins.
