WikiLeaks announced that it was temporarily stopping publication Monday to “aggressively fundraise” in order to stay afloat.

A financial blockade by Bank of America, VISA, MasterCard, PayPal and Western Union has destroyed 95% of WikiLeaks’ revenue, organization founder Julian Assange said.

“Our scarce resources now must focus entirely on fighting this unlawful banking blockade,” Assange said. “If this financial attack stands unchallenged, a dangerous, oppressive and undemocratic precedent will have been set, the implications of which go far beyond WikiLeaks and its work.”

Speaking in front of a backdrop that showed upside-down logos of VISA, MasterCard, Bank of America and PayPal, Assange said his organization, which facilitates the anonymous leaking of secret information, had been running off cash reserves for 11 months.

Many financial institutions stopped doing business with the site after it published a trove of confidential U.S. diplomatic cables late last year, and donations have been stymied.
