Would you open an email from one Dr Brian Fisher? GP app staff did – and they got phished

Director's account hijacked in what biz believes to be an attempted ransomware attack


GP online services app Evergreen Life has been the target of a cyber-attack attempting to access the British firm's corporate email accounts.

A malicious phishing email was sent to all the addresses in Evergreen clinical director Dr Brian Fisher's inbox – a rather unfortunate name given the circumstances – in what the company believes to be a man-in-the-middle (MITM) attack.

The original message, sent on Monday from Fisher's account and seen by The Register, read: "Did you get the documents I sent you this morning? Find attached. I will await your feedback on the highlighted items."

Mark Hindle, chief operating officer at Evergreen, told The Register that a bogus website had been registered three days before the email was sent. The threat was detected before the systems were accessed, but he believes it may have been an attempted ransomware attack.

"We have made the details available to the Information Commissioner's Office, although this was not a breach of our patient information – as our core patient systems are kept separate."

He said Fisher's address may have been used because of his large number of contacts, lobbying work and prominence within the company.

Yesterday the group issued a follow-up email with the subject line: "Important security alert: action required."

The email, also seen by The Reg, said:

You have been highlighted as a recipient of an email from Brian Fisher on Monday 21st October at around 14:15 to 14:30 with the subject line "FW: Brian Fisher has shared a document with you via OneDrive for Business."

Please do NOT:
Open the attachment
Click on the link
Fill in your username and password on the bogus site

If you have already clicked on this link and typed in your credentials, then we suggest the following:
Change your Office365/e-mail password with immediate effect.
Log onto Office
Go to your account menu (top right)
Reset your password

It continued: "Evergreen Life has already implemented a number of measures to mitigate this particular threat, including immediate steps to blacklist the bogus website. That took several hours yesterday, which is why we strongly recommend that you change your Office 365 password if you did inadvertently submit any credentials."

The email also noted that "phishing" is the most common type of cyber-attack against organisations such as Evergreen.

"Phishing attacks can take many forms, but they all share a common goal – getting you to share sensitive information such as login credentials, credit card information, or bank account details. Although we maintain controls to help protect our networks and computers from cyber threats, we rely on you to be our first line of defence."

On its website Evergreen says: "We have extensive experience in writing large software systems for hospitals – over 60 years between us. We understand how important your data is, we are used to working in very secure environments, and have taken a lot of time to do things right." ®

  • US won’t prosecute ‘good faith’ security researchers under CFAA
    Well, that clears things up? Maybe not.

    The US Justice Department has directed prosecutors not to charge "good-faith security researchers" with violating the Computer Fraud and Abuse Act (CFAA) if their reasons for hacking are ethical — things like bug hunting, responsible vulnerability disclosure, or above-board penetration testing.

    Good-faith, according to the policy [PDF], means using a computer "solely for purposes of good-faith testing, investigation, and/or correction of a security flaw or vulnerability."

    Additionally, this activity must be "carried out in a manner designed to avoid any harm to individuals or the public, and where the information derived from the activity is used primarily to promote the security or safety of the class of devices, machines, or online services to which the accessed computer belongs, or those who use such devices, machines, or online services."

  • Intel plans immersion lab to chill its power-hungry chips
    AI chips are sucking down 600W+ and the solution could be to drown them.

    Intel this week unveiled a $700 million sustainability initiative to try innovative liquid and immersion cooling technologies to the datacenter.

    The project will see Intel construct a 200,000-square-foot "mega lab" approximately 20 miles west of Portland at its Hillsboro campus, where the chipmaker will qualify, test, and demo its expansive — and power hungry — datacenter portfolio using a variety of cooling tech.

    Alongside the lab, the x86 giant unveiled an open reference design for immersion cooling systems for its chips that is being developed by Intel Taiwan. The chip giant is hoping to bring other Taiwanese manufacturers into the fold and it'll then be rolled out globally.

    The US government has recovered over $15 million in proceeds from the 3ve digital advertising fraud operation that cost businesses more than $29 million for ads that were never viewed.

    "This forfeiture is the largest international cybercrime recovery in the history of the Eastern District of New York," US Attorney Breon Peace said in a statement

    The action, Peace added, "sends a powerful message to those involved in cyber fraud that there are no boundaries to prosecuting these bad actors and locating their ill-gotten assets wherever they are in the world."
