Last updated: November 2025 | Reading time: 10 minutes

Phishing Prevention

Phishing is one of the biggest threats to Mars Market users. Scammers create fake sites that look identical to Mars Market to steal login credentials and funds.

Phishing is the #1 Threat: More users lose funds and accounts to phishing than any other type of scam. Always verify you're on the correct site before entering any information.

How to Avoid Phishing

  • Verify URLs character by character: Phishing sites use similar-looking addresses
  • Only use trusted mirror sources: Bookmark our mirrors page
  • Never click links in messages: Type addresses manually or use bookmarks
  • Enable 2FA: Even if credentials are stolen, 2FA protects your account
  • Check site functionality: Phishing sites often have broken features
  • Verify PGP signatures: Official announcements should be signed

Signs of a Phishing Site

  • Slightly different URL (characters swapped, extra letters)
  • Certificate warnings or missing HTTPS on clearnet pages
  • Unusual login errors or captcha behavior
  • Requests for information the real site wouldn't ask for
  • Visual differences from the legitimate site
  • Links in unsolicited messages or emails

Exit Scam Detection

Exit scams occur when a marketplace or vendor collects money and then disappears without delivering products or services. Recognizing warning signs early can protect your funds.

Marketplace Exit Scam Warning Signs

  • Sudden policy changes favoring the platform
  • Delays in withdrawals or "maintenance" periods
  • Staff departures or reduced support
  • Reduced activity from established vendors
  • Rumors from multiple independent sources
  • Requiring new deposits or fees unexpectedly
  • Disabled dispute system or altered escrow terms

Vendor Exit Scam Warning Signs

  • Sudden increase in listings or aggressive pricing
  • Requesting FE (Finalize Early) when they didn't before
  • Reduced communication or quality
  • Recent negative feedback mentioning non-delivery
  • Offering unusual deals that seem too good
  • Long-established vendor suddenly changing behavior

Protecting Yourself

  • Never keep large balances in marketplace wallets
  • Deposit only what you need for immediate purchases
  • Monitor darknet news and community discussions
  • Be especially cautious during "crisis" periods
  • Trust patterns of behavior over single data points

Vendor Verification

Choosing trustworthy vendors is critical for safe marketplace use. Take time to research before ordering.

What to Check

  • Feedback History: Read recent reviews, not just overall rating
  • Time on Platform: Established vendors are generally safer
  • Number of Sales: More completed orders indicate reliability
  • Verification Status: Check for platform verification badges
  • Response Time: Professional vendors respond promptly
  • Terms and Policies: Clear, reasonable terms indicate professionalism

Red Flags in Vendor Profiles

  • Very new account with no history
  • Prices significantly below market rate
  • Requiring FE (Finalize Early)
  • Vague product descriptions
  • No PGP key or terms listed
  • Recent cluster of negative reviews
  • Claims that sound too good to be true

Common Scam Types

FE (Finalize Early) Scams

Scammers convince buyers to finalize before receiving products, then never ship. Remember: legitimate vendors don't require FE, and once you finalize, buyer protection is gone.

Selective Scamming

Vendors deliver to most customers but scam occasional buyers, maintaining positive feedback while stealing from some. Large orders or new buyers are common targets.

Impersonation Scams

Scammers create accounts with names similar to legitimate vendors (different characters, added numbers). Always verify exact vendor name and profile.

Private Transaction Scams

Scammers convince you to transact outside the marketplace to "save fees." Without escrow protection, you have no recourse if they don't deliver.

Harm Reduction Practices

Harm reduction focuses on minimizing negative consequences. These practices can help reduce risks when using darknet marketplaces.

General Harm Reduction

  • Start small—make small test orders before larger purchases
  • Research thoroughly—knowledge reduces risk
  • Use escrow—never pay outside the system
  • Stay anonymous—protect your identity at every step
  • Keep records—document transactions for disputes
  • Trust but verify—don't rely solely on ratings

Community Resources

Various online communities discuss marketplace safety and vendor experiences. While information should be verified from multiple sources, community knowledge can provide valuable insights. Be cautious of shills and astroturfing.

Summary: Warning Signs Checklist

Proceed with extreme caution if you observe:
  • Requests to finalize early
  • Offers to transact outside the marketplace
  • Prices that seem too good to be true
  • Pressure to act quickly
  • New accounts or unverified vendors
  • Recent negative reviews mentioning non-delivery
  • Withdrawal delays or unusual fees
  • Links from untrusted sources
  • Requests for unusual information
  • Vendors who won't communicate through proper channels

Safety Frequently Asked Questions

If you believe you've been scammed: 1) Don't finalize if you haven't already, 2) Open a dispute immediately with detailed evidence, 3) Contact marketplace support, 4) Document everything, 5) Leave honest feedback to warn others. Unfortunately, if you've finalized or transacted outside escrow, recovery options are very limited.

Generally, no. FE removes all buyer protection. Some buyers choose to FE with highly established vendors they've used many times successfully, but even these vendors can exit scam. The safest practice is to never FE regardless of vendor reputation or promises of discounts.

Verify mirrors through multiple independent sources. Check our mirrors page, community forums, and official signed announcements. Compare the address character by character. When in doubt, don't enter credentials—seek verification first. Consider keeping known-good bookmarks.

This is a major red flag. Legitimate vendors keep all communication on-platform where it's documented and escrow protection applies. Off-platform communication removes accountability and protections. Decline and consider reporting the vendor.
