UK schools should remove pupils’ online photos as AI blackmail threat grows, say experts

UK schools should remove pictures of pupils’ faces from their websites and social media accounts because blackmailers are using them to create sexually explicit images, experts have said.Child safety experts and the UK’s National Crime Agency (NCA) warn that criminals are using AI to manipulate photos of children and then demand cash not to publish them.They are recommending educational institutions remove identifiable pictures of children from their websites and social media accounts – or consider not using them at all.The Internet Watch Foundation (IWF) said an unnamed UK secondary school had recently been subjected to a blackmail attempt after criminals used the institution’s website or social media accounts to take photos of schoolchildren and then, using AI tools, turned them into child sexual abuse material (CSAM).The blackmailers sent the images to the school and threatened to publish them online if they did not receive money.

The IWF, which monitors CSAM online, used a digital tool to turn the blackmail images into a “hash”, or digital fingerprint, which was shared with leading tech platforms in order to prevent them from being uploaded.The watchdog said 150 of the images from the secondary school blackmail attempt could be classified as CSAM under UK law.Jess Phillips, the minister for safeguarding and violence against women and girls, said the attempted blackmailing of schools was a “deeply worrying emerging threat” and laws on use of AI to create explicit images would be updated if necessary, having announced a ban on possessing AI models designed to generate CSAM.“We will not hesitate to go further if necessary and make sure our laws stay up to date with the latest threats,” she said.The IWF said the secondary school incident, which happened late last year, is not the only blackmail attempt involving manipulated school website or social media account photos that it is aware of in the UK.

The IWF is not naming the school involved in the incident last year, or the police force that contacted it seeking help in blocking distribution of the images,A UK advisory body on tackling online harms, the early warning working group (EWWG), has issued guidance to schools on protecting pupils from blackmailers,Although the problem is not widespread, the group is concerned it is “only a matter of time” before more schools are targeted,The group recommended schools remove images that show a student face-on and instead publish images that are harder to misuse, such as pictures taken from a distance, blurred images or portraits taken from behind a pupil,The advice warned against publishing “identifiable information” that could be used to harm or blackmail an individual, such as “names or faces”.

Schools should also consider whether they need pupil photos at all, said the guidance, stating that establishments should mull over “whether using imagery without children and young people’s faces can still achieve your objectives”.This included “celebrating achievements more safely” by showcasing milestones “while minimising risks”.Avoiding the use of names or full names in labelling photos will reduce the risk of blackmail, the advice added, while applying privacy settings to a school website or social media account will limit who can view or share content.A checklist of actions recommended by the EWWG included conducting regular audits of children’s images on websites, social media accounts and promotional material and regularly seeking re-signing of image consent agreements.If an incident occurs, the group advised schools to contact the police immediately, retain any criminal images and remove from view the original images that had been tampered with.

The EWWG’s members include the NSPCC charity, the IWF, the Welsh government, Education Scotland, the Safeguarding Board for Northern Ireland and the NCA.The Confederation of School Trusts (CST), whose academy schools educate more than four million primary and secondary schoolchildren across England, said schools would “carefully consider” the guidance and find the “right balance” between “celebrating pupils … and keeping everyone safe”.“As educators we instinctively want to celebrate children’s achievements and that includes sharing photos and videos of all the good things that go on in our schools – it is deeply depressing that in doing so we potentially have to contend with threats from abusers and scammers,” said Leora Cruddas, CST chief executive.Blackmailing people over intimate images is known as sextortion and the crime has a become increasingly prevalent, with the advent of generative AI tools giving criminals a new way of extorting victims.Typically, sextortion involves manipulating a child or adult into sending intimate images or videos of themselves and then threatening to send the images to friends or relatives, or release them online, if the victim does not send money or more explicit images.

Sextortion has been linked to the suicides of several British teenagers who have killed themselves after receiving extortion threats.In 2024, the Guardian reported the threat was evolving due to advances in AI, with one teenager being sent a fake “nude” image of herself that appeared to have been taken from her Instagram account.The Report Remove service, which allows children to flag explicit images or videos of themselves that have appeared – or could appear – online, said sextortion attempts are increasing.Last year it received 394 reports from under-18s of blackmail attempts after the victims had been manipulated into sending sexual images to predators.The figure is 34% higher than in 2024.

Sextortion has been carried out by criminal gangs based outside the UK, with the NCA pointing to west Africa and Nigeria as hubs.It is understood that the secondary school sextortion attempt involved the use of terms that appear in negotiation “scripts” used by sextortion gangs.Some schools have already taken action after an increase in the threat from AI tools.Last year, the Loughborough Schools Foundation, which represents three private schools, redesigned its website to remove recognisable images of pupils.

Swinney keen to work with fellow nationalist devolved leaders in UK

John Swinney has said he plans to work with the nationalist first ministers in Wales and Northern Ireland in a coordinated opposition to Labour’s policies on the cost of living and UK government spending.The Scottish National party leader said he had spoken to Michelle O’Neill, the Sinn Féin first minister of Northern Ireland, on Friday night after she had called to congratulate him on his party’s “emphatic” victory in the Holyrood elections.Swinney, who will be sworn in as Scotland’s first minister next week, said he expected Plaid Cymru’s leader, Rhun ap Iorwerth, to be appointed first minister of Wales after winning the Senedd elections for the first time on Thursday.He said he “looked forward to making sure our respective countries’ voices are heard loud and clear in the UK”.O’Neill, who has to work jointly with the Democratic Unionist party in Stormont, so has limits to her authority, had made clear her enthusiasm for all three nationalist-led governments working in concert, Swinney added

Starmer brings in Gordon Brown and Harriet Harman to ease pressure on him to resign

Keir Starmer has brought in Gordon Brown and Harriet Harman as advisers in a move to ease the mounting pressure on the prime minister to resign after the disastrous election results for Labour.Brown, the former prime minister and long-serving chancellor under Tony Blair, has been made Starmer’s envoy on global finance, with a brief to advise on financial partnerships to help with defence-related investments, particularly with Europe.Harman, who was Labour’s deputy leader under Brown, will be the prime minister’s adviser on women and girls, focusing on tackling violence and improving economic opportunities.While the roles are part-time and unpaid, there is deliberate symbolism in Starmer gathering Labour heavyweights around him as he battles to save his job, particularly with the optics of Brown being pictured with him at Downing Street on Saturday morning.With the bulk of the votes now counted from Thursday’s series of elections, Labour lost more than 1,400 councillors across England, shedding support to Reform UK and the Greens in traditional heartlands

British leader Keir Starmer under pressure after heavy election losses

Keir Starmer, the British prime minister, is facing increasing pressure to set a date for his departure after elections across much of the country resulted in massive losses for his ruling Labour party.With the bulk of results now counted after voting on Thursday, Labour had lost more than 1,400 representatives from English councils, the local government structures that deliver many neighbourhood services.Starmer’s party also crashed to defeat in the election for the devolved parliament of Wales, where it had dominated the country’s politics for a century, and went backwards in representation in the Scottish parliament.Adding to the panic in Labour, the party lost to a series of challengers, including the rightwing populist Reform UK party, the leftwing Greens, and pro-independence nationalists in Wales and Scotland.The elections, the biggest since Starmer won power in mid-2024, showed how the UK’s traditional two-party system of Labour and the Conservatives has been smashed, with Reform taking the most votes, and the Greens, Conservatives, Labour and the centrist Liberal Democrats bunched up behind

The SNP may have won again but Scottish politics has been upended

Long before the final votes were counted in Scotland, veteran Labour politicians said it was a defeat made in Downing Street.When the Scottish Labour leader, Anas Sarwar, strode into the Glasgow count arena on Friday afternoon flanked by sombre-faced activists, the scene was a mirror image to the same venue in 2024, when his resurgent party won 36 seats from the Scottish National party, playing a significant part in Keir Starmer’s landslide victory.Two years later, Starmer’s unpopularity proved an insurmountable obstacle for Sarwar, despite record donations to Scottish Labour and a formidable electoral machine, honed over the past five years. And with only a handful of constituencies declared, he decided to concede defeat before the real scale of Labour losses across the country was known.More than 12 hours later, when the final regional results were declared after 1am, it was clear that Holyrood politics had been upended

Most Labour members think Starmer cannot revive party fortunes, poll finds

The majority of Labour members say they do not believe Keir Starmer can turn around the party’s fortunes, while 45% say the prime minister should step down.The mayor of Greater Manchester, Andy Burnham, was the first preference for 42% of members, who were asked to rank their preferred successor.Several Labour MPs – especially those who are close to Burnham – have told the Guardian that they would like to see a timetable for Starmer to stand down in an orderly and dignified way, including allowing the mayor time to seek a parliamentary seat.The poll was conducted just before Thursday’s elections, where Labour was fighting on all fronts, in local elections in England and parliamentary elections in Wales and Scotland. Nigel Farage’s Reform UK won hundreds of seats and control of more councils in England, Labour went backwards in Scotland as the SNP claimed a historic fifth victory and Plaid Cymru ended a century of Labour dominance in Wales, unseating the Labour first minister Eluned Morgan

John Swinney urges Starmer to show Scotland ‘greater respect’ after SNP victory

John Swinney, the Scottish National party leader, has challenged Keir Starmer to show “greater respect” to the Scottish government after winning the Holyrood elections by a comfortable margin.The Scottish National party secured a record fifth term in office on Friday after securing 58 of Holyrood’s 129 seats.In a dramatic conclusion to the day’s counting, Labour and Reform UK were left tied on 17 seats each after Highlands council finally finished its regional list count at 1.10am on Saturday, 16 hours after counting began.With Labour enduring its worst result since devolution in 1999, this puts the Scottish parliament in the unprecedented position of having two parties in joint second place, adding to Labour’s humiliation
