First reported death connected to misfired ransomware attack on German hospital

By Cameron Abbott and Keely O’Dowd

News reports have surfaced that a woman in Germany has died due to a delay in receiving medical care. What is most concerning about this death is the circumstances in which the woman tragically passed away.

According to reports, the woman needed urgent medical treatment and the hospital she presented to, Duesseldorf University Hospital, was unable to admit her as it was dealing with a ransomware attack.

The hackers exploited a vulnerability in a widely used commercial add-on software. This attack caused a failure in the hospital’s IT systems resulting in it being unable to access data and diverting emergency patients elsewhere. The woman was redirected to a hospital approximately 30km away from Duesseldorf University Hospital, which led to a delay in the woman receiving treatment. Unfortunately the delay proved fatal and the women passed away before she could be treated.

Can It Get Any Worse? Travel Giant CWT pays $4.5 Million USD ransom to Hackers who Stole Corporate Files and Knocked 30,000 Computers Offline

By Cameron Abbott and Max Evans

In these unprecedented times, where travel around the globe is primarily halted as nations get to grips with controlling the outbreak of COVID-19, many would think it couldn’t get any worse for travel companies. However, they would be wrong, as according to an article from ITNews, American travel management giant CWT has reportedly paid a whopping 414 bitcoin, equivalent to a value of 4.5 Million USD (approximately 6.3 Million AUD), to hackers who successfully exfiltrated over 2 terabytes of sensitive corporate files.

According to the Article, the successful hackers used a strain of ransomware referred to as “Ragnar Locker” which places computer files into a virtual prison through encryption and renders them unusable until the victim pays for the keys. Then in CWT had to negotiate in a public chat forum to pay for the release.  It gives us a rare insight into the dialogue that followed. CWT negotiated the hackers down from their initial demand of 10 Million USD. According to the Report, whilst the hackers claimed to have stolen over 2 terabytes of files including financial reports, security documents and employees’ personal data, it was not clear whether any customer data was compromised.

Interlopers in Things? IoT devices may be used as backdoors to your network

By Cameron Abbott and Karla Hodgson

This month Microsoft reported that its Threat Intelligence Center discovered that IoT (internet of things) devices – a VOIP phone, a printer and a video decoder – were used to gain access to corporate networks in April.

Microsoft have identified Strontium – also known as Fancy Bear or APT28 – as the culprit, a hacker group associated with the Russian government who appear to be targeting government, IT, military and defence, engineering, medical and education sectors. Strontium has been linked to the hacking of Hillary Clinton’s presidential election campaign and of the email accounts of researchers investigating the missile strike on MH17 and the Skripal poisonings. In the last 12 months alone Microsoft has delivered almost 1,400 notifications to those targeted or compromised by Strontium.

Hackers to take the blame for Census?

By Cameron Abbott and Rebecca Murray

The Australian Bureau of Statistics (ABS) says that the 2016 online census form was subject to “four Denial of Service attacks,” which prompted the ABS to shut down its Census website as a security precaution on Tuesday night. Read the ABS’s media release here.

While the ABS maintains that 2 million forms were successfully submitted and safely stored, thousands of Australians were prevented from taking part in the Census due to the website crash. The ABS has revealed that it believes that the attacks came from overseas and were a deliberate attempt to sabotage the census. However, we are wondering if the entire Australian population accessing the website at the same time might look like a Denial of Service attack in its own right! If ever a system should have been robust enough to cope with such an attack it was this one.

Attorney-General George Brandis has stated that the security measures in place were “more than sufficient to protect individual privacy” and that “the cyber security operations centre has been engaged overnight…and is investigating the matter.”
