Global task force claims tech firms “blindfold themselves to child sexual abuse.”

The long-running battle over encryption between tech companies and law enforcement continues, with law enforcement agencies around the world calling on Meta to cancel plans for end-to-end encryption of Facebook and Instagram messages.

End-to-end encryption (often called “E2EE”) boosts security and privacy for all users, whether law-abiding or not. But government officials have long opposed plans to make the technology more widely available, citing the risk that terrorists, sex traffickers, child abusers, and other criminals will use encrypted messages to evade law enforcement.

The latest call to abandon encryption plans was made today by the Virtual Global Taskforce, a consortium of 15 law enforcement agencies, including two from the US: the FBI and ICE Homeland Security Investigations. The task force focuses specifically on child sexual abuse; other members include Europol and agencies from the UK, Canada, Colombia, Australia, New Zealand, Kenya, the Philippines, the United Arab Emirates, the Netherlands, and South Korea.

“The announced implementation of E2EE on Meta platforms Instagram and Facebook is an example of a purposeful design choice that degrades safety systems and weakens the ability to keep child users safe,” the global task force said in a statement on the UK National Crime Agency’s website.

“Meta is currently the leading reporter of detected child sexual abuse to NCMEC,” the task force said, referring to the US-based National Center for Missing & Exploited Children. Meta hasn’t provided any indication “that any new safety systems implemented post-E2EE will effectively match or improve their current detection methods,” according to the group.

“The abuse will not stop just because companies decide to stop looking,” the group also said, accusing Meta and other tech companies of “blindfolding themselves to child sexual abuse.”

End-to-end encryption is available in Facebook Messenger and Instagram as an option, but the law enforcement statement was likely spurred by Meta’s plan to turn the security feature on by default in Facebook Messenger sometime this year. The Meta-owned WhatsApp already has end-to-end encryption enabled by default.

National Crime Agency (UK) News:

Global law enforcement coalition urges tech companies to rethink encryption plans that put children in danger from online abusers 

The Virtual Global taskforce is calling for all industry partners to fully appreciate the impact of implementing system design decisions that result in blindfolding themselves to child sexual abuse (CSA) occurring on their platforms, or reduces their capacity to identify CSA and keep children safe.

It is time to confront these concerns and make tangible steps towards possible solutions that we know exist.

The Virtual Global Taskforce is an international alliance of 15 dedicated law enforcement agencies, of which the National Crime Agency is the chair, working alongside Affiliate members from private industry and non-governmental organisations to tackle the threat of child sexual abuse (CSA).

The VGT issued its first position statement on end-to-end encryption (E2EE) in 2021. This statement highlighted the devastating impact E2EE can have on law enforcement’s ability to identify, pursue and prosecute offenders, when implemented in a way that affects the detection of CSA on industry platforms. It is important to update the VGT position on E2EE in the context of impending design choices by industry.

As outlined in our previous statement, there is no doubt that encryption plays an important role in safeguarding privacy, however this must be balanced with the importance of safeguarding children online.

The VGT encourages industry to respond and consider the following:
Only to implement platform design choices, including E2EE, at scale alongside robust safety systems that maintain or increase child safety. 
Where the child user base and risk is high, a proportionate investment and implementation of technically feasible safety solutions is paramount. 
The abuse will not stop just because companies decide to stop looking. We all have a role to play in protecting children in online spaces and we strongly urge industry partners to take active steps toward this goal.

Current landscape
The scale of online CSA is increasing worldwide. The WeProtect Global Alliance have identified it as one of the most urgent and defining issues of our generation. The number of reports of CSA from industry continue to be staggering, but demonstrates the key role that industry plays both in protecting children online and in reporting cases to law enforcement for action.

The National Center for Missing and Exploited Children (NCMEC) received 29.3 million reports of suspected CSA in 2021, a 35% increase from 2020. Of this 29.3 million, over 29.1 million reports came from electronic service providers.

Although these reports result in a range of different outcomes globally, what is consistent is that they significantly contribute to positive outcomes for child safety. These figures demonstrate the current success of industry partners in detecting and reporting CSA occurring on their platforms, resulting in victims being identified and safeguarded.

Design and investment choices implemented in a way that interferes with the effectiveness of such safety systems threaten to undermine these successes which have been consistently built upon over previous decades.

The announced implementation of E2EE on META platforms Instagram and Facebook is an example of a purposeful design choice that degrades safety systems and weakens the ability to keep child users safe.

META is currently the leading reporter of detected child sexual abuse to NCMEC. The VGT has not yet seen any indication from META that any new safety systems implemented post-E2EE will effectively match or improve their current detection methods.

Case study
By way of an example of the impact E2EE implementation could have, the following case from the United Kingdom would not have been possible without Facebook having access to message content, an ability they will lose under E2EE.

David Wilson is one of the most prolific child sexual abuse offenders the UK’s National Crime Agency has ever investigated. Wilson used META (Facebook) to contact thousands of children, grooming hundreds of victims using fake online profiles. By pretending to be a teenage girl, he manipulated victims to send sexually explicit material of themselves and in some cases, blackmailed victims into abusing their siblings and friends. Some victims were so traumatised they spoke of wanting to end their own lives.

The successful prosecution of Wilson and the resulting safeguarding of hundreds of children was possible because law enforcement were able to access the evidence contained within over 250,000 messages through Facebook. In an E2EE environment, it is highly unlikely this case would have been detected.
