A Russian-operated darknet marketplace, run by the group Karma Fullz, is trafficking in the identities of former U.S. visa holders who have since left the country. These synthetic identities, which include Social Security numbers, clean credit histories, and tax records, are being sold on a Telegram-based platform that exploits gaps in U.S. tracking of departed visa holders. The marketplace offers three tiers of identity packages, with the most valuable being aged ex-patriot identities priced at over $1,000 due to their rich credit histories and higher fraud success rates.
Fraudsters are using these identities to open new bank accounts, apply for credit cards, claim fraudulent tax refunds, and access public benefits, all while appearing as legitimate users within U.S. financial systems. Financial institutions often fail to detect these reactivated identities due to a lack of effective monitoring for such activity, according to experts at SentiLink. The operation highlights a significant vulnerability in U.S. fraud risk management and underscores the need for improved detection mechanisms for synthetic identity fraud.

Reporting published in December 2025 described how Karma Fullz enhanced the credibility of these identities with Experian account setups, aged email addresses, and public-record registrations, making detection harder for financial institutions. The coverage also highlighted gaps in tracking departed visa holders and calls from experts such as SentiLink's David Maimon for more targeted fraud-detection measures.
Data from former immigrants from countries including Ukraine, Lithuania, and China was used in fraudulent U.S. financial and benefits applications, including bank accounts, credit cards, tax refunds, and public benefits. The reporting says such misuse was observed as recently as July 2025.
A Russian-operated darknet marketplace run by the Karma Fullz group was established in September 2024 to sell synthetic identities built from data belonging to former U.S. visa holders who had returned to their home countries. The market operated via Telegram and offered multiple tiers of identity packages, including higher-value aged identities.
