'Little weirdo' shoulder surfer teaches UK cabinet minister a lesson in cybersecurity

(2024/05/24)


In setting the date for the UK's next general election, prime minister Rishi Sunak this week essentially announced the start of open season for political reporters all hunting for the top scoop of the day by any means necessary. He may need, however, to brief his ministers on basic opsec if he's going to stop any more internal memos from reaching the front pages.

On May 22, less than 24 hours before [1]PM Sunak said July 4 would be the day UK citizens decide on their next leader, The Times published a [2]gem sourced from photos taken of veterans' affairs minister Johnny Mercer's laptop on a public train.

It's an example of shoulder surfing – a type of social engineering technique that involves peering at other people's devices to discover secrets like passwords, PINs, sensitive emails, and the like.

[3]

We're not sure what's worse here, the cyber hygiene gaffe and abject failure to protect internal party comms from the prying eyes of the British public traveling from Exeter to London, or the fact that along with his laptop Mercer was papped with his bare feet cheesing out the first-class carriage. For shame, Johnny.

[4]

[5]

For those whose interests extend beyond the mere cybersecurity aspects of this story, the photos revealed Mercer's memo criticizing Downing Street for giving the PM too much airtime and should instead be offering more public speaking gigs to more popular members of the Conservative party, such as Kemi Badenoch and Penny Mordaunt.

Among a long list of complaints, Mercer accused campaign managers of trying to "placate" Sunak and overlooking the likes of Badenoch and Mordaunt in favor of "average performers" such as transport secretary Mark Harper.

[6]

Mercer also wrote "I don't feel part of the team", presumably referring to being left out in some way by party leaders. This was after he accused special advisers of being "overpromoted and underskilled" and having "poor political judgments."

The mind baffles as to why the Tories may not be leaning more hewavily on Mercer.

Perhaps more illuminating on the current government's attitude towards voting, Mercer also appeared to suggest that the Conservatives were suppressing votes from specific demographics.

His memo states that he was upset that his attempts to let military veterans, who had previously been turned away from polling stations, use their ID cards to prove their identity when voting had been denied. Downing Street special advisers apparently blocked these proposals because it could also "open the floodgates" and allow students to also use their ID cards too.

Beware of nosy parkers

The idea of [11]shoulder surfing has been around for well over a decade but if you look around for some examples, you'll find more sources simply explaining the concept itself than real-world cases of it causing actual harm.

Mercer's case is certainly the only one this reporter has encountered affecting something as sensitive as a governing political party's internal comms.

Last year, John Roch of London's Metropolitan Police [12]issued a warning about criminals shoulder surfing people entering PINs for their [13]banking apps and then swiftly stealing the phone to drain their accounts.

[14]

While it's not common, Roch said there have been cases where criminals also try the same PIN with other finance apps, and trawl through notes apps for any other credentials of use, presumably before selling the device as quickly as possible.

Over in the US, Daniel Jermaine Usher, 26, of South Los Angeles, was previously found guilty of [15]shoulder surfing elderly ATM users and draining their accounts, and while that's undoubtedly nasty behavior, it's still not as high profile as perusing secret government memos.

We got in touch with the Cabinet Office to ask for comment and find out if ministers are briefed on the dangers of shoulder surfing, but it hadn't responded by the time of publication.

While we wait for a response from the UK gov, we can instead turn to Mercer's X account, which is where he responded to The Times' scoop by calling the public transport snapper a "little weirdo."

"So some little weirdo has gone round snapping my laptop reading private messages from a private email account," Mercer [16]Xeeted . "My shoes and socks were off because I'd just cycled across Dartmoor in the rain.

"Shoot me now. Or grow up." ®

It's been a battle making sure we don't let customers just walk into our office where they can see our screens. And I must've shouted "Windows+L" hundreds of times at people getting up from their desk.

People at my office still like me... i think...

Our head of security used to just walk into peoples offices and send emails from their unlocked machines.

I'd like to say it helped, but at least the supply of free cakes was nice.

Madness is trying the same thing again and expecting different results. Telling users repeatedly to do something and expecting them to listen.

A design or engineering solution is required. There are plenty to choose from, starting with office layout, translucent dividers, narrow-angle privacy screens, computers that detect the proximity of a work-issued ID card or mobile phone, pressure sensors in the chair, face recognition on the web cam...

Re: Situational awareness is rare

While i do agree with you on the most part, if people are willing this definitely helps with building habits. It's a small office i work at, and they mostly respond with "oh yeah i should do that". If you're just shouting angrily at people who are unwilling to change, you're not getting anywhere.

I do agree that you get the best results if the solution doesn't require interaction. I'm a huge fan of auto-locking devices, unfortunately we don't have compatible cameras at every desk, but the windows hello camera-based auto-lock is amazing. Even came across some laptops that actually detect when someone is shoulder surfing and dim the screen, or turn it off. That can get quite annoying though, sometimes you just want to show something on your screen to a colleague.

Re: Situational awareness is rare

heyrick

Easier fix - if your screens have confidential information on them, why are outsiders permitted to enter the office? Our HR has two rooms. One we go in to talk to the HR girl, and the other one where going into (*any* excuse including "the building is on fire") is an immediate sanctionable action.

Re: Situational awareness is rare

OTOH setting the building on fire is an extreme way to deal with HR.

Create a bonus pot. For instance 500 per employee (depends on how you value security).

Nominate someone to walk through the office each week and if there is unattended unlocked computer, let them take a picture (using company secure phone) or hire security person.

Remove every person with recorded violation from the bonus pool. Distribute the bonus amongst employees without the violation, after paying % the nominated employee for taking the pictures (if it wasn't done by security).

If a person gets removed from the bonus pool, they'll have to attend mandatory security training.

If they get violation again, give them final warning and sack them on third strike.

Using technology to change behaviour (IME) rarely works, either someone senior enough to have influence will object to it and become an exception which immediately dilutes the purpose of the policy, or the company implements the technology but does not include compliance with IT policies in their code of conduct so HR can't do anything to stop repeat offenders.

Used to do security audits for a firm and every year was the same, passwords blank, non-expiring, written on post-its, shared accounts all over the place, browsing habits that would even shock the people looking at "tractors" in parliament. Document it all, write it up, then a year later find the same people were doing the same things. My firm were getting very well paid to visit all their sites for this audit, but they never did anything we recommended until a password was compromised by a disgruntled former employee. Even then most of the directors wanted to be made exceptions to the new password policy.

General Purpose

A keyboard with a single key - for example at top right - that performs Windows-L. It still requires user action (and keeps the user in control) but tapping the corner of your keyboard as you stand up is simple, obvious and gets results - all good for engraining it.

[1]Privacy screens for laptops have been around for ages. They should be mandatory for anyone using a government (or indeed corporate) laptop in public places. This is not rocket surgery, so why hasn't it become the norm?

Re: Basic failure

Lurko

I'd agree, but they've still got a certain angle of view. If you've genuinely concerned about the privacy of what's on your screen then don't have that content on screen in a public place. I don't expect much of MPs, Mercer is a former soldier, he really should know better than this, and know when to take some responsibility.

Then again, this government has never taken responsibility for anything.

Re: Basic failure

Cruachan

"Then again, this government has never taken responsibility for anything."

Not defending our (soon to be ex) Government, but they are not unique in this and I'm sure their successors will be just as bad for taking responsibility, as indeed all previous administrations have been too.

Re: Basic failure

Anonymous Coward

Yup, the key point here is public space.

Re: Basic failure

0laf

I'm sure MPs and ministers are offered lots of training to avoid such situations but as is usual with people in power despite being people of interest and at high risk of targetted attacks they usually consider themselves too important to make themselves available for training or listen to training if they actually turn up.

It must be a bloody nightmare to be a parliamentary infosec manager.

Dan 55

Nice to see Mercer's taken time out from defending the nation against Carol Vorderman to warn us about little wierdos. Was he talking about the PM?

Typical reaction

ibmalone

Doesn't inspire much confidence really, well known security risk (at a university and /we/ get trained on this, Mercer makes a big deal about his army background), but the reaction is to play the 'weirdo' card as if it's somehow cheating or unforseeable. See also Trump and the overweight people in their parents' basement accusation. As if the odder (and by implication in both cases more pathetic) the person who waltzed through your security the more understandable it was.

Is it 'cheating'? Depends who defines the rules of the game. Is it utterly foreseeable? Yes. Is "I was being stupid and got caught out by some weirdo" a reasonable excuse? No.

Socks

Dave 126

Carry spare socks. Wear leather shoes. Wash and dry between your toes. Place cotton wool between your toes if you are really struggling to keep them dry. Dry your shoes when not wearing them by using a shoe tree or fans - don't use heat.

Civil service is probably getting training about security including the risk of shoulder surfing.

Do ministers also get it? If so, it may be the case "the rules for the pleb don't apply to me. Who would have dared to look at the screen of the me almighty anyway?".

It's comforting though, that soon these types will be flushed out of the system.

Re: Pride

Remember to register to vote folks!

I was shocked that voter suppression as suggested by the shoulder surfing isn't a dirty little secret but overt (caretaker) government policy. This prat was complaining about his veteran mates being suppressed not the principle itself.

So in addition to registering to vote also ensure you have the required identity documents to cast a vote.

Here in AU the toryoid* (LNP) government (at the time) unsuccessfully attempted this piece of contemptible skulduggery.

Having compulsory voting and registration makes voter id largely unnecessary.

High time the UK adopted both preferential voting and mandatory voting and ditch the lords for an elected regional representative assembly.

* like haemorhhoids but involving the genitourinary tract.

Re: Pride

0laf

I thought it was practically common knowledge that the whole policy was designed on the basis that the demographic for labour voters was less likely to hold or carry the required ID than those those people making up the Conservatve voting demographic. Therefore decreasing the Labour voting percentage via a side channel attack..

The same thing goes for redrawing constituency boundaries which practically every government does when they get in.

As for voter ID, it's always necessary. When you go to vote, how do they know if you're who you say you are? Chances are very good the voting officer doesn't know you by sight after all.
