Andrew Orr ·

Researcher Fabian Bräunlein found that Apple’s Find My location network can be used to “upload arbitrary data to the internet.”

GitHub Adds Support for Security Keys Over SSH

Andrew Orr ·

GitHub announced on Monday that it enabled support for two-factor authentication security keys when members use them over SSH.

When used for SSH operations, security keys move the sensitive part of your SSH key from your computer to a secure external security key. SSH keys that are bound to security keys protect you from accidental private key exposure and malware. You perform a gesture, such as a tap on the security key, to indicate when you intend to use the security key to authenticate. This action provides the notion of “user presence.”

Finnish Mental Health Startup Vastaamo Leaked Patient Data

Andrew Orr ·

Vastaamo ran the largest network of private mental-health providers in Finland. William Ralston tells the story on WIRED, and how hackers used the data to threaten patients.

A security flaw in the company’s IT systems had exposed its entire patient database to the open internet—not just email addresses and social security numbers, but the actual written notes that therapists had taken. A group of hackers, or one masquerading as many, had gotten hold of the data.

What an incompetent company. No anonymization of patient records, no encryption of data. In other words, unfortunately common. Two developers hired at Vastaamo were even arrested in a previous security breach.

There is a portion of this cryptographic puzzle that continues to elude organizations—millions, perhaps even billions of dollars, exist within cryptowallets.

Experian’s API Exposed Credit Scores for Anyone to Discover

Andrew Orr ·

Credit bureau Experian recently fixed a flaw in its API that let anyone find a credit score of a person by typing in their name and mailing address.

Demirkapi declined to share with Experian the name of the lender or the website where the API was exposed. He refused because he said he suspects there may be hundreds or even thousands of companies using the same API, and that many of those lenders could be similarly leaking access to Experian’s consumer data.
