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

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.

As the world grinds to a halt following the perpetuation of COVID-19, more and more businesses have turned to remote work arrangements. This has led to a sharp rise in the use of videoconferencing technology Zoom. However, as the Australian Financial Review notes, flawed data security and privacy practices mean that the use of Zoom could be disastrous for corporate and personal privacy.

Concerns surrounding the use of Zoom arose earlier this year, with critical security vulnerabilities enabling hackers to predict Meeting ID’s and therefore join active meetings, and also allowing any website to forcibly join a user to a Zoom call with their video camera activated and without the user’s permission. Whilst a number of these errors were patched up, as the article notes, Zoom refused to disable the ability for hackers to forcibly join to a call anyone visiting a malicious site, raising security red flags and undermining public confidence in Zoom’s attitude towards data security. A strange response given that part of its attraction had been a perceived stronger approach to security.
