Credential stuffing during COVID-19: Cybersecurity firm purchased over 500,000 Zoom account credentials on the dark web and hacker forums

In what could only be adding fuel to the fire that is the growing concern over Zoom’s privacy and data security risks, it has been reported that over 500,000 Zoom accounts were sold on the dark web and hacker forums earlier in April. The accounts were purchased by cybersecurity firm Cyble after it noticed free Zoom accounts were being posted on hacker forums.

Cyble was able to purchase approximately 530,000 Zoom credentials, which included a user’s email address, password, personal meeting URL, and their HostKey (a six-digit number used to host meetings on Zoom). Victims included well-known companies such as Chase, Citibank and educational institutions including the University of Colorado and the University of Florida. According to Cyble, credentials belonging to its clients in the bulk purchase were also confirmed to be correct.

Not So Zoomy: Use of Videoconferencing Technology “Zoom” on the Rise, but Privacy and Data Security Inadequacies suggest Users should Tread Carefully

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.
