The researchers suggested several solutions, such as enabling encryption between the hosts in the hospital’s radiology network, digital signatures with a secure mark on each scan or hidden digital watermarks

Patients’ CT and MRI scan results can be easily changed by hackers, thereby deceiving radiologists and Artificial Intelligence (AI) algorithms that diagnose malignant tumours, Israeli researchers have warned.

The researchers from the Ben-Gurion University (BGU) showed that hackers could access to add or remove medical conditions from lung cancer scans for the purposes of insurance fraud, ransom and even murder, Xinhua news agency reported.

As part of the attack, the hacker has full control over the number, size and location of the cancers while preserving the anatomy from the original, full resolution three-dimensional (3D) image.

To prove the feasibility of the attacks, the researchers broke with permission into an actual hospital network to intercept all CT (computed tomography) scans.

Although the hospital internal network is not connected to the internet, hackers can access it via the hospital’s WiFi or physical access to the infrastructure, the researchers said.

To inject and remove medical conditions, the researchers used a deep learning neural network called a generative adversarial network (GAN), which has been used in the past to generate realistic imagery, such as portraits of non-existent people.

After the “attack” the radiologists at the hospital misdiagnosed 99 per cent of the scans showing malignant tumours, and 94 per cent of altered images with cancerous images removed.

After the radiologists were informed about the attack, they still misdiagnosed 60 per cent of altered scans falsely showing tumours and 87 per cent of those falsely showing no sign of the tumour, the report showed.

The researchers suggested several solutions, such as enabling encryption between the hosts in the hospital’s radiology network, digital signatures with a secure mark on each scan or hidden digital watermarks. (IANS)

In a unique online fraud, hackers are tricking people into thinking that they own compensation after being victims of personal data frauds, and under the pretext of offering them money, are fleecing them, a new report said on Monday.

Experts at cybersecurity firm Kaspersky detected this new online fraud scheme where scammers urge users to buy ‘temporary US social security numbers’ worth around $9 each.

Victims were found in Russia, Algeria, Egypt and the UAE as well as other countries.

The scheme involves a website allegedly owned by the Personal Data Protection Fund, founded by the US Trading Commission.

The fund issues compensation to those who may have been subject to a personal data leak and is available to citizens from any country in the world.

For those interested, the site offers to check whether user data has ever been leaked.

For this, one needs to provide their specific surname, first name, phone number, and social media accounts.

Once this has been done, an alert is shown indicating that the user has experienced a leak, which can include data such as photos, videos, and contact information, entitling the user to compensation of thousands of dollars.

“However, fraudsters do not just ask for a user to enter a bank card number and wait for the payment to be credited; users inevitably need to offer their own social security numbers,” the report noted.

In any possible scenario – be it the absence of the SSN or entering the correct existing SSN – the website alerts mistakes and offers to sell a temporary one for the $9 price.

Upon agreement, the victim is redirected to this payment form in Russian or English with the purchase price specified in rubles or dollars, respectively. The specific form depends on the victim’s IP address, the experts noted.

“The scammers themselves are most likely Russian speakers, as suggested by the request for payments in rubles, plus the suspicious similarity of the scheme to other easy money offers that regularly tempt residents of Russia and the CIS (Commonwealth of Independent States),” said Tatyana Sidorina, Security expert at Kaspersky.

The e-bait in those schemes varies — giveaways, surveys, secret retirement savings, even a part-time job as a taxi dispatcher — but they tend to be in Russian (as are some of the preceding links).

The bottom line is always the same: the juicy promise of quite a bit of easy money, followed by a demand to pay for an inexpensive service, be it a commission, a ‘securing’ payment, or a temporary SSN.

“The new scheme is quite a topical one and is related to offering compensation for data leaks. Once some organizations have started to pay users, fraudsters decided there is a monetary opportunity for them as well,” Sidorina added.
