Over the past 15+ years in both white and black hat cybersecurity environments, I’ve gained insights into various tools, techniques, and strategies used in the ever-evolving landscape of internet-based income—legal and otherwise. One of the most controversial and rapidly evolving niches in this space is crypto draining. This thread is not a promotion or encouragement of illegal activities—this is an educational breakdown meant to shed light on how some actors operate within the underground ecosystem. Understanding these tactics can help ethical hackers, researchers, and security professionals better protect systems, users, and assets.


What Is Crypto Draining?​


Crypto draining refers to a method where unsuspecting users approve malicious smart contracts or sign transactions that give attackers permission to drain their crypto wallets. Often, this is executed through highly deceptive scam pages that mimic real platforms, projects, or NFT launches. Once a victim interacts with such a page, they may unknowingly give access to their assets.


This tactic began gaining traction during the NFT boom about four years ago. The rapid adoption of decentralized wallets and the public's limited understanding of how wallet permissions worked created a perfect storm for widespread exploitation. In some reported incidents, individuals lost millions in a matter of seconds.


The Anatomy of a Draining Campaign​


Let’s break down the 3 core components behind any draining operation:


1. Crypto Drainer Script (The Tool)


At the heart of any crypto draining campaign is the drainer script itself. These are pre-written programs capable of mimicking legitimate wallet interactions, tricking users into approving malicious smart contracts.


Among the most talked-about tools in underground forums are names like:


  • Exogator
  • Angel
  • Inferno

Out of these, Exogator stands out for a few reasons:


  • Comes with a comprehensive guide (over 100 steps on installation and usage)
  • Offers pre-designed scam pages to mimic trending NFT and DeFi launches
  • Includes a "money cleaning" feature, so any funds transferred to the attacker’s wallet are "washed" through various steps
  • Offers credit-based page creation (useful for scaling)
  • Subscription model starts from $199/month, compared to others charging $1,500/year

This script is often updated to bypass new security measures from major wallets and blockchain platforms. Its modular design allows users to customize scam pages for different use cases or campaigns.


2. Crypto Traffic Generation (The Strategy)


A drainer script alone does nothing. What fuels it is targeted crypto traffic. The traffic strategy used will directly influence both the success rate and scale of the campaign.


Key traffic generation tactics used in draining operations include:


  • Email blasts targeting crypto users with fake airdrops or wallet alerts
  • SMS marketing campaigns crafted with urgency (e.g., “Your wallet is at risk! Connect now.”)
  • Social engineering via Discord, Telegram, Twitter, and even Reddit, where links to fake "free mint" or staking platforms are shared
  • Paid ads on shady ad networks targeting crypto audiences
  • SEO manipulation, often used to push fake pages that look like official launchpads or new DeFi tools
  • CPA/CPC campaigns run through blackhat ad networks using clickbait-style creatives

Traffic targeting is all about precision. The best campaigns focus on crypto-savvy audiences, particularly those who are active in NFT communities, trading forums, and DeFi platforms. Gaming audiences also rank high, as they often overlap with crypto adopters.


3. Targeting Projects (The Angle)


While the tool and traffic are crucial, target selection often determines success or failure. Draining campaigns thrive on hype. The most successful operations target:


  • New NFT projects
  • Launchpad token sales
  • DAO voting events
  • Staking or farming protocols with fresh buzz
  • Wallet migration notices

The idea is to ride the wave of a trending project. Timing is everything. If you clone or imitate a popular project that’s just launched—or is about to launch—you’ll have a far better chance of catching users off-guard.


For instance, if an NFT project announces a public mint scheduled for tomorrow, a drainer campaign can go live today, mimicking that mint page and luring in traffic from Discord, Twitter, or Google searches.


Targeting accounts for about 30% of the campaign’s effectiveness. If the audience doesn’t trust or recognize the project being mimicked, conversion (or in this case, wallet interaction) will remain low.


Key Takeaways from This Breakdown​


  • Drainer scripts like Exogator are highly modular and advanced, with built-in scam page templates and laundering tools.
  • Traffic is king. Without a reliable crypto-focused traffic source, no draining campaign will succeed. Skills in advertising, email, and social engineering are crucial.
  • Project selection is as important as the tool and traffic. Pick trending projects with a large, hyped community for maximum success.
  • These tactics are illegal, and running them can lead to serious legal consequences. This information is shared purely for educational and security awareness purposes.

Why Security Professionals Should Pay Attention​


If you're a developer, a DeFi project manager, or a wallet provider, knowing how these systems work under the hood is critical to improving wallet warnings, contract transparency, and community education. Anti-drain solutions must keep evolving because drainer tools like Exogator are constantly being updated to bypass existing protections.

Final Words​


Crypto draining is a powerful example of how social engineering, technical scripting, and market awareness come together in high-stakes cybercrime. By dissecting this underground industry, we empower ethical hackers and security teams to anticipate attacks, educate users, and strengthen the ecosystem.
