Software bug at firm left NHS data ‘vulnerable to hackers’

The NHS is “wanting into” allegations that affected person knowledge was left weak to hacking because of a software program flaw at a non-public medical companies firm.

The flaw was discovered final November at Medefer, which handles 1,500 NHS affected person referrals a month.

The software program engineer who found the flaw believes the issue had existed for no less than six years.

Medefer says there isn’t any proof the flaw had been in place that lengthy and confused that affected person knowledge has not been compromised.

The flaw was fastened a number of days after being found.

In late February the corporate commissioned an exterior safety company to undertake a evaluation of its knowledge administration techniques.

An NHS spokesperson stated: “We’re wanting into the issues raised about Medefer and can take additional motion if applicable.”

Medefer’s system permits sufferers to guide digital appointments with docs, and offers these clinicians entry to the suitable affected person knowledge.

Nonetheless, the software program bug, found in November, made Medefer’s inner affected person file system weak to hackers, the engineer stated.

The software program engineer, who doesn’t wish to be named, was shocked by what he uncovered.

“When I discovered it, I simply thought ‘no, it could possibly’t be’.”

The issue was in bits of software program known as APIs (software programming interfaces), which permit completely different pc techniques to speak to one another.

The engineer says that at Medefer these APIs weren’t correctly secured, and will probably have been accessed by outsiders, who would have been capable of see affected person info.

He stated it was unlikely that affected person info was taken from Medefer, however that with out a full investigation, the corporate couldn’t have identified for positive.

“I’ve labored in organisations the place, if one thing like this occurred, the entire system could be taken down instantly,” he stated.

On discovering the flaw the engineer informed the corporate that an exterior cybersecurity professional needs to be introduced in to analyze the issue, which he says the corporate didn’t do.

Medefer says the exterior safety company has confirmed that it has discovered no proof of any breach of knowledge and that each one the corporate’s knowledge techniques had been presently safe.

It says the method of investigating and fixing the API flaw was “extraordinarily open”.

Medefer stated it had reported the difficulty to the ICO (Data Commissioner’s Workplace) and the CQC (Care High quality Fee), “within the pursuits of transparency”, and that the ICO had confirmed there isn’t any additional motion to be taken as there isn’t any proof of a breach.

The engineer, who had been contracted in October to check for flaws within the firm’s software program, left the corporate in January.

In a press release Dr Bahman Nedjat-Shokouhi, founder and CEO of Medefer, stated: “There is no such thing as a proof of any affected person knowledge breach from our techniques.”

Dr Nedjat-Shokouhi added: “We take our duties to sufferers and the NHS very critically. We maintain common exterior safety audits of our techniques by unbiased exterior safety businesses, undertaken on a number of events yearly.”

Cybersecurity specialists, who’ve checked out info equipped by the software program engineer, have expressed their concern.

“There’s the chance that Medefer saved knowledge derived from the NHS not as securely as one would hope it might be,” stated Prof Alan Woodward, a cybersecurity professional on the College of Surrey.

“The database is perhaps encrypted and all the opposite precautions taken, but when there’s a means of glitching the API authorisation, anybody who is aware of how may probably acquire entry,” he added.

One other professional identified that as Medefer offers with highly-sensitive, medical knowledge, the corporate ought to have introduced in cybersecurity specialists as quickly as the issue was recognized.

“Even when the corporate suspected that no knowledge was stolen, when going through a difficulty that would have resulted in a knowledge breach, particularly with knowledge of the character in query, an investigation and affirmation from a suitably certified cybersecurity professional could be advisable,” says Scott Helme, a safety researcher.

Medefer was based in 2013 by Dr Nedjat-Shokouhi, with a aim to enhance outpatient care. Since then its expertise has been utilized by NHS trusts throughout the nation.

“Particular person NHS organisations should guarantee they meet their authorized tasks and nationwide knowledge safety requirements to guard affected person knowledge when appointing suppliers, and we provide them assist and coaching nationally on how this needs to be achieved.”
