PlayStation Network in the context of "Sony Interactive Entertainment"

PlayStation is a video gaming brand owned and produced by Sony Interactive Entertainment (SIE), a division of Japanese conglomerate Sony. Its flagship products consists of a series of home video game consoles produced under the brand; it also consists of handhelds, online services, magazines, and other forms of media.

The brainchild of Sony executive Ken Kutaragi, the brand began with the first PlayStation home console released in Japan in 1994 and worldwide the following year, which became the first console of any type to ship over 100 million units, which made PlayStation a globally recognized brand. Since then there have been numerous newer consoles—the most recent being the PlayStation 5 released in 2020—while there have also been a series of handheld consoles and a number of other electronics such as a media center and a smartphone. The main series of controllers utilized by the PlayStation series is the DualShock, a line of vibration-feedback gamepads. SIE also operate numerous online services like PlayStation Network, the PlayStation Store, and the subscription-based PlayStation Plus, which may also offer non-gaming entertainment services; the PlayStation Network has over 103 million active users monthly as of December 2019.

LulzSec (a contraction for Lulz Security) is a grey hat computer hacking group that claimed responsibility for several high profile attacks, including the compromise of user accounts from PlayStation Network in 2011. The group also claimed responsibility for taking the CIA website offline. Some security professionals have commented that LulzSec has drawn attention to insecure systems and the dangers of password reuse. It has gained attention due to its high profile targets and the sarcastic messages it has posted in the aftermath of its attacks. One of the founders of LulzSec was computer security specialist Hector Monsegur, who used the online moniker Sabu. He later helped law enforcement track down other members of the organization as part of a plea deal. At least four associates of LulzSec were arrested in March 2012 as part of this investigation. Prior, British authorities had announced the arrests of two teenagers they alleged were LulzSec members, going by the pseudonyms T-flow and Topiary.

At just after midnight (BST, UT+01) on 26 June 2011, LulzSec suddenly released a "50 days of lulz" statement, which they claimed to be their final release, confirming that LulzSec consisted of six members, and that their website was to be shut down. Their final release included accounts and passwords from many different sources. Despite claims of retirement, the group committed another hack against newspapers owned by News Corporation on 18 July, defacing them with false reports regarding the death of Rupert Murdoch. The group had also helped launch Operation AntiSec, a joint effort involving LulzSec, Anonymous, and other hackers.

The PlayStation 3 (PS3, initially stylized in all caps) is a home video game console developed and marketed by Sony Computer Entertainment (SCE). It is the successor to the PlayStation 2, and both are part of the PlayStation brand of consoles. The PS3 was first released on November 11, 2006, in Japan, followed by November 17 in North America and March 23, 2007, in Europe and Australasia. It competed primarily with Microsoft's Xbox 360 and Nintendo's Wii as part of the seventh generation of video game consoles.

The PlayStation 3 was built around the custom-designed Cell Broadband Engine processor, co-developed with IBM and Toshiba. SCE president Ken Kutaragi envisioned the console as a supercomputer for the living room, capable of handling complex multimedia tasks. It was the first console to use the Blu-ray disc as its primary storage medium, the first to be equipped with an HDMI port, and the first capable of outputting games in 1080p (Full HD) resolution. It also launched alongside the PlayStation Network online service and supported Remote Play connectivity with the PlayStation Portable and PlayStation Vita handheld consoles. In September 2009, Sony released the PlayStation 3 Slim, which removed hardware support for PlayStation 2 games (though limited software-based emulation remained) and introduced a smaller, more energy-efficient design. A further revision, the Super Slim, was released in late 2012, offering additional refinements to the console's form factor.
