Mossack Fonseca, the beleaguered law firm at the center of the international Panama Papers scandal, has announced that it is closing its doors. The firm cited “reputational deterioration” that has caused “irreversible damage.”
Founded in 1977 by Jurgen Mossack and Ramon Fonseca, Mossack Fonseca had been perched at the top of offshore legal services providers until April 2016, when it became ground zero for a global controversy because approximately 11.5 million of the firm’s internal legal and financial documents were leaked to the media. These leaked documents – publicized primarily by the International Consortium of Investigative Journalists (“ICIJ”) – allegedly reveal a global system of undisclosed offshore accounts, money laundering and tax evasion, and how the rich and powerful around the world use shell companies to conceal assets and possible illegal activity.
The incident is the largest publicly disclosed data breach involving a law firm. Following the April 2016 publication of data, founding partner Ramon Fonseca and other public sources claimed that the firm’s network had been compromised by hackers sometime in 2015. Security researchers and other public sources identified numerous unpatched vulnerabilities in Mossack’s website and email server, which could have been very easily compromised by hackers. Approximately 2.6 terabytes of data – including 4.8 million emails, 3 million database files, and 2.1 million.pdf files – were leaked, including client documents dating back to the 1970s. Approximately one year after the alleged data theft, ICIJ published the Mossack data and set off numerous investigations into the firm and its clients.
