Leaders of the Polish government agreed to meet today to review their stance on copyright protection policies after Anonymous this weekend took down government Web sites.

The attacks were focused on the Web sites of the country's parliament, president, and prime minister, leaving them inaccessible to visitors since Sunday. Anonymous took credit for the hacks via a message on Twitter that read, "Dear Polish government, we will continue to disrupt and interfere with your government official websites until the 26th. Do not pass ACTA."

The Anti-Counterfeiting Trade Agreement (ACTA) is a proposed framework that would institute new international standards regarding intellectual property and the measures used to enforce their protection. Just a few months ago in October, major nations including the U.S., Japan, Australia, Canada, Morocco, New Zealand, Singapore, and South Korea agreed to move forward with the proposal during a meeting in Tokyo.

Just last week the Polish government announced plans to join the agreement on Jan. 26, prompting an outcry from various Internet rights groups, the most vocal being Anonymous. To date, the Anonymous attack is the most high-profile protest of the possible move by the Polish government and reportedly included an intrusion into the laptop of Michal Boni, Poland's Minister of Administration and Digitization.

In addition to the hacks, the group posted a video message on YouTube, which said, in part, "Creating legal uncertainty for Internet companies, ACTA would become a major threat to freedom of expression online and another assault against the culture of sharing on the Internet. Poland believes that they can successfully get away with passing this agreement, however this will not occur From this point until January 26th, we will disrupt and attack Polish government websites, leaking documentations and emails. We will show the government of Poland that they can't censor the people. To Polish government, this is your last chance...reject ACTA or face consequence from the people. Operation Anti-ACTA."

The various hacking incidents seem to have had the desired effect as the Polish government announced today that it will now review its stance on signing the ACTA agreement, according to the AP. When the news was made public, Anonymous updated its Twitter feed with the statement, "Thanks to our actions Michal Boni (Minister of Digitalization), has said he'll talk about ACTA with Prime Minister tomorrow."

The decision comes on the heels of the widespread last week against the Stop Online Piracy Act (SOPA) and the PROTECT IP Act (PIPA), which prompted bill sponsors to delay action on both pieces of legislation.
