Bumble: Exfiltrating a victim's exact location (to within 5m)

I used Bumble's distance feature to exfiltrate the exact location to within approx 5m of a victim. I did this by using the Bumble API to move my attacker account's location around the approximate area of the victim. I was able to obtain the exact distance between attacker and victim at 3 separate...

Extortion, precision malware, and ruthless scams. Read the State of Malware 2021 report

Last year, threat actors took advantage of the COVID-19 public health crisis in a way previously considered unimaginable, not only preying on uncertainty and fear during the initial months of the global pandemic, but retooling attack methods, reneging on promises, strengthening malware, and...

kernel: use-after-free in cdev_put() when a PTP device is removed while it's chardev is open

There is a use-after-free problem seen due to a race condition between the release of ptpclock and cdev while resource deallocation. When a high privileged process allocates a ptp device file like /dev/ptpX and voluntarily goes to sleep. During this time if the underlying device is removed, it ca...
