Robocall Results from a Telephony Honeypot

Posted on by

A group of researchers set up a telephony honeypot and tracked robocall behavior: NCSU researchers said they ran 66,606 telephone lines between March 2019 and January 2020, during which time they said to have received 1,481,201 unsolicited calls — even if they never made their phone numbers public via any source. The research team said they usually received an unsolicited… Continue reading Robocall Results from a Telephony Honeypot→

In this paper, we ask, "What are the… Continue reading Adversarial Machine Learning and the CFAA→

Fawkes: Digital Image Cloaking

Posted on by

Fawkes is a system for manipulating digital images so that they aren’t recognized by facial recognition systems. At a high level, Fawkes takes your personal images, and makes tiny, pixel-level changes to them that are invisible to the human eye, in a process we call image cloaking. You can then use these "cloaked" photos as you normally would, sharing them… Continue reading Fawkes: Digital Image Cloaking→

Hacking a Power Supply

Posted on by

This hack targets the firmware on modern power supplies. (Yes, power supplies are also computers.) Normally, when a phone is connected to a power brick with support for fast charging, the phone and the power adapter communicate with each other to determine the proper amount of electricity that can be sent to the phone without damaging the device­ — the… Continue reading Hacking a Power Supply→
