ICO probes NHS clinic's data blunder that exposed HIV+ status of 800 patients

56 Dean Street drops perhaps the worst DP clanger of all time

The ICO is looking into a data blunder at 56 Dean Street, a sexual health clinic operated as part of Chelsea and Westminster NHS Foundation Trust, after it emailed the HIV positive status of nearly 800 patients to the entire group.

The data breach was committed through the email circulation of the clinic's "OptionE" newsletter to HIV positive patients, which did not use the “BCC” field to protect those patients' identities, and instead listed all of them in the "CC" field.

A spokesperson from the Information Commissioner's Office told The Register that the watchdog was "aware of an incident regarding the 56 Dean Street clinic and is making enquiries."

A copy of the email and subsequent responses were published by beyondpositive, an online magazine for people living with HIV in the UK.

The initial email circulated the clinic's latest newsletter and revealed all of the 780 recipients' emails and names in the "CC" fields.

A second email was quickly sent out in an attempt to recall the previous missive, requesting recipients delete the previous email. However this, again, included the email addresses of all recipients in the "CC" field.

Finally, an apology email from Theresa Burns did manage to BCC the recipients, providing a helpline for the affected patients and stating:

We apologise for this error ... Clearly this is completely unacceptable. We are urgently investigating how this has happened and I promise you that we will take steps to ensure it never happens again. We will send you the outcome of the investigation.

The Register was unable to contact a representative for the clinic at time of publication, but it has seen an email sent out to patients, which explained the action taken by the NHS Trust immediately after the data gaffe had occurred.

It said it had reported the mishap to the health service's information watchdog, suspended group email messages from being sent until "human error" can be prevented and informed the Trust's board of the "serious incident".

An internal investigation is also under way, apparently.

The Guardian quoted a spokesbeing who claimed that the breach was caused by a human error and added that the particular employee responsible was distraught. ®

  • AI tool finds hundreds of genes related to human motor neuron disease

    Breakthrough could lead to development of drugs to target illness

    A machine-learning algorithm has helped scientists find 690 human genes associated with a higher risk of developing motor neuron disease, according to research published in Cell this week.

    Neuronal cells in the central nervous system and brain break down and die in people with motor neuron disease, like amyotrophic lateral sclerosis (ALS) more commonly known as Lou Gehrig's disease, named after the baseball player who developed it. They lose control over their bodies, and as the disease progresses patients become completely paralyzed. There is currently no verified cure for ALS.

    Motor neuron disease typically affects people in old age and its causes are unknown. Johnathan Cooper-Knock, a clinical lecturer at the University of Sheffield in England and leader of Project MinE, an ambitious effort to perform whole genome sequencing of ALS, believes that understanding how genes affect cellular function could help scientists develop new drugs to treat the disease.

  • Need to prioritize security bug patches? Don't forget to scan Twitter as well as use CVSS scores

    Exploit, vulnerability discussion online can offer useful signals

    Organizations looking to minimize exposure to exploitable software should scan Twitter for mentions of security bugs as well as use the Common Vulnerability Scoring System or CVSS, Kenna Security argues.

    Better still is prioritizing the repair of vulnerabilities for which exploit code is available, if that information is known.

    CVSS is a framework for rating the severity of software vulnerabilities (identified using CVE, or Common Vulnerability Enumeration, numbers), on a scale from 1 (least severe) to 10 (most severe). It's overseen by First.org, a US-based, non-profit computer security organization.

    US companies should be on the lookout for security nasties from Ukrainian partners following the digital graffiti and malware attack launched against Ukraine by Belarus, the CISA has warned.

    In a statement issued on Tuesday, the Cybersecurity and Infrastructure Security Agency said it "strongly urges leaders and network defenders to be on alert for malicious cyber activity," having issued a checklist [PDF] of recommended actions to take.

    "If working with Ukrainian organizations, take extra care to monitor, inspect, and isolate traffic from those organizations; closely review access controls for that traffic," added CISA, which also advised reviewing backups and disaster recovery drills.
