Industrialization of Cybercrime - The Age of the Expanding Black Market (Late 2000s)

In the late 2000s, as e-commerce and online banking became an infrastructure for daily life, and credit card transactions and personal information flowed online in large volumes, criminals with a financial motive began to organize rapidly. BBSs and dark web exchanges sprang up, and criminal activities became more efficient through the "division of labor" and "reuse," literally turning into an industry.

In the criminal supply chain, exploit kits, which automate vulnerability attacks, form the nucleus of the criminal enterprise. Once infiltrated, they are distributed en masse via botnets and evade tracking by frequently switching command servers (C2) via DGA (domain auto-generation) and Fast-Flux DNS. The division of roles has become the norm: cryptors/packers encrypt and obfuscate malware to slip past detection, and pay-per-install (PPI) and spam distributors take on the task of spreading the infection.

The main players in the theft are form grabbers/keyloggers that extract input information and banking trojans that hijack money transfer screens. From the compromised terminal, credentials stored in the browser, VPN/RDP credentials, and even email and cloud sessions are "commercialized" and sold on the black market along with phishing kits (a set of fake sites that anyone can use) and "initial access rights" to the compromised server. The "commercialized" information was sold on the black market along with phishing kits (a set of fake sites that anyone can use) and "initial access rights" to compromised servers. In addition, credit card information (CVVs) and "fulls" (names, addresses, birthdates, accounts) are traded with price lists, and bullet-proof hosting and anonymous relays are used to protect the infrastructure.

At the monetization end, a money mule network distributes and cleans remittances. Payments initially rely on the e-money ecosystem (e.g., centralized money transfer services), but the proliferation of crypto assets and mixers/tumblers eventually encouraged the "invisibility of funds. Ransomware, which sprouted around 2005, expanded through RaaS (service-as-a-service) in the 2000s, establishing a "business model" in which developers, affiliates, and negotiators divide the workload.

Law enforcement, hampered by borders, anonymity, and encryption, countered with OSINT/threat intelligence sharing, sandbox analysis, EDR, and enhanced fraud detection (behavioral analysis and machine learning) on the financial side, but this was only the tip of the iceberg in many cases. --Cybercrime thus became a "complete supply chain" of tools, personnel, infrastructure, and money laundering, and grew into a black economy that rivals the real economy.
