NEWS RELEASE SUMMARY – March 24, 2020
San Diego – A Russian-based cyber platform known as DEER.IO was shut down by the FBI today, and its suspected administrator – alleged Russian hacker Kirill Victorovich Firsov – was arrested and charged with crimes related to the hacking of U.S. companies for customers’ personal information.
DEER.IO was a Russian-based cyber platform that allowed criminals to purchase access to cyber storefronts on the platform and sell their criminal products or services. DEER.IO started operations as of at least October 2013, and claimed to have over 24,000 active shops with sales exceeding $17 million. The platform was shut down pursuant to a seizure order issued by the Southern District of California Court.
FBI agents arrested Firsov, a Russian cyber hacker, on March 7 in New York City. Firsov not only managed the DEER.IO platform, he also advertised it on other cyber forums, which catered to hackers. Firsov is next scheduled to appear on April 16, 2020, before U.S. Magistrate Judge Allison H. Goddard.
According to a federal complaint, DEER.IO virtual stores offered for sale a variety of hacked and/or compromised U.S. and international financial and corporate data, Personally Identifiable Information (PII), and compromised user accounts from many U.S. companies. Individuals could also buy computer files, financial information, PII, and usernames and passwords taken from computers infected with malicious software (malware) located both in the U.S. and abroad. Law enforcement found no legitimate business advertising its services and/or products through a DEER.IO storefront. Store operators and customers accessed the storefront via the Internet. Specifically, in this case, the FBI made purchases from DEER.IO storefronts hosted on Russian servers.
The DEER.IO platform offered a turnkey online storefront design and hosting platform, from which cybercriminals could advertise and sell their products (such as harvested credentials and hacked servers) and services (such as assistance performing a panoply of cyber hacking activities). The DEER.IO online stores were maintained on Russian-controlled infrastructure. The DEER.IO platform provided shop owners with an easy-to-use interface that allowed for the automated purchase and delivery of criminal goods and services.
Once shop access was purchased via the DEER.IO platform, the site then guided the newly-minted shop owner through an automated set-up to upload the products and services offered through the shop and configure crypto-currency wallets to collect payments for the purchased products and/or services.
As of 2019, a cybercriminal who wanted to sell contraband or offer criminal services through DEER.IO could purchase a storefront directly from the DEER.IO website for 800 Rubles (approximately $12.50) per month. The monthly fee was payable by Bitcoin or a variety of online payment methods such as WebMoney, a Russian based money transfer system similar to PayPal.
A cybercriminal who wanted to purchase from storefronts on the DEER.IO platform could use a web browser to navigate to the DEER.IO domain, which resolved to DEER.IO storefronts. DEER.IO contained a search function, so individuals could search for hacked accounts from specific companies or PII from specific countries, or the user could navigate through the platform, scanning stores advertising a wide array of hacked accounts or cyber criminal services for sale. Purchases were also conducted using cryptocurrency, such as Bitcoin, or through the Russian-based money transfer systems.
On or about March 4, 2020, the FBI purchased approximately 1,100 gamer accounts from the DEER.IO store ACCOUNTS-MARKET.DEER.IS for under $20 in Bitcoin. Once payment was complete, the FBI obtained the gamer accounts, including the user name and password for each account. Out of the 1,100 gamer accounts, 249 accounts were hacked Company A accounts. Company A confirmed that if a hacker gained access to the user name and password of a user account, that hacker could use that account. A gamer account provides access to the user’s entire media library. The accounts often have linked payment methods, so the hacker could use the linked payment method to make additional purchases on the account. Some users also have subscription-based services attached to their gamer accounts.
On or about March 5, 2020, the FBI purchased approximately 999 individual PII accounts from the DEER.IO store SHIKISHOP.DEER.IS for approximately $170 in Bitcoin. On that same date, the FBI purchased approximately 2,650 individual PII accounts from the DEER.IO store SHIKISHOP.DEER.IS for approximately $522 in Bitcoin. From those identities, the FBI identified names, dates of birth and U.S. Social Security numbers for multiple individuals who reside in San Diego County, including G.V. and L.Y.
“There is a robust underground market for hacked stolen information, and this was a novel way to try to market it to criminals hoping not to get caught,” said U.S. Attorney Robert Brewer. “Hackers are a threat to our economy, and our privacy and national security, and cannot be tolerated.”
FBI Special Agent in Charge Omer Meisel stated, “Deer.io was the largest centralized platform, which promoted and facilitated the sale of compromised social media and financial accounts, personally identifiable information (PII) and hacked computers on the internet. The seizure of this criminal website represents a significant step in reducing stolen data used to victimize individuals and businesses in the United States and abroad. The FBI will continue to be at the forefront of protecting Americans from foreign and domestic cyber criminals.”
The office extends its appreciation to the New York Division of U.S. Customs and Border Protection operating at John F. Kennedy International Airport and to private sector cyber-security company Black Echo LLC, which provided assistance throughout the investigation.
