Britain First

Britain First, also known by the abbreviation BF, is a far‑right organization headquartered in the United Kingdom. The group maintains an online presence through Twitter accounts, a YouTube channel and official websites, which it uses to disseminate its political messages and mobilize supporters. Its activities are characterized by opposition to immigration and Islam, positioning it within the broader spectrum of extremist political movements in the UK. The organization's structure and leadership are not detailed in the available sources, but its public identifiers are consistently referenced as Britain First or BF.

On 12 April 2017, Britain First suffered a coordinated cyberattack that compromised multiple digital assets simultaneously. Attackers renamed the Twitter profile of one of the group's leaders, altered web content linked to the deputy leader, and leaked the personal addresses of several key figures. The organization's YouTube channel was also targeted; one video was removed by the platform for harassment violations, while the remaining 178 videos appeared to have been deleted by user action, effectively emptying the channel. Official websites associated with the group were similarly disrupted, with content modified or taken offline during the incident.

The cyberattack resulted in a significant disruption of Britain First's online operations and exposed sensitive personal information of its members. Despite the extent of the breach, the identity of the perpetrators was never disclosed, leaving the attack unattributed. The incident highlighted vulnerabilities in the group's digital security practices and demonstrated how extremist organizations can be affected by coordinated hacking efforts. Following the attack, the group attempted to restore its online presence, though the long‑term impact on its reach and capabilities remains unspecified in the sources. The event serves as a concrete example of how far‑right entities can be targeted in the cyber domain, affecting both their communication channels and the privacy of their affiliates.
