What Graykey Can and Can’t Unlock

Posted on by

This is from 404 Media:

The Graykey, a phone unlocking and forensics tool that is used by law enforcement around the world, is only able to retrieve partial data from all modern iPhones that run iOS 18 or iOS 18.0.1, which are two recently released versions of Apple’s mobile operating system, according to documents describing the tool’s capabilities in granular detail obtained by 404 Media. The documents do not appear to contain information about what Graykey can access from the public release of iOS 18.1, which was released on October 28.

Security Analysis of the MERGE Voting Protocol

Interesting analysis: An Internet Voting System Fatally Flawed in Creative New Ways.

Abstract: The recently published “MERGE” protocol is designed to be used in the prototype CAC-vote system. The voting kiosk and protocol transmit votes over the internet and then transmit voter-verifiable paper ballots through the mail. In the MERGE protocol, the votes transmitted over the internet are used to tabulate the results and determine the winners, but audits and recounts use the paper ballots that arrive in time. The enunciated motivation for the protocol is to allow (electronic) votes from overseas military voters to be included in preliminary results before a (paper) ballot is received from the voter. MERGE contains interesting ideas that are not inherently unsound; but to make the system trustworthy—to apply the MERGE protocol—would require major changes to the laws, practices, and technical and logistical abilities of U.S. election jurisdictions. The gap between theory and practice is large and unbridgeable for the foreseeable future. Promoters of this research project at DARPA, the agency that sponsored the research, should acknowledge that MERGE is internet voting (election results rely on votes transmitted over the internet except in the event of a full hand count) and refrain from claiming that it could be a component of trustworthy elections without sweeping changes to election law and election administration throughout the U.S…

The Scale of Geoblocking by Nation

Posted on by

Interesting analysis:

We introduce and explore a little-known threat to digital equality and freedom­websites geoblocking users in response to political risks from sanctions. U.S. policy prioritizes internet freedom and access to information in repressive regimes. Clarifying distinctions between free and paid websites, allowing trunk cables to repressive states, enforcing transparency in geoblocking, and removing ambiguity about sanctions compliance are concrete steps the U.S. can take to ensure it does not undermine its own aims.

The paper: “…

This feels important:
The Secret Service has used a technology called Locate X which uses location data harvested from ordinary apps installed on phones. Because users agreed to an opaque terms of service page, the Secret Service believes it doesn&#821… Continue reading Secret Service Tracking People’s Locations without Warrant→

Why Italy Sells So Much Spyware

Posted on by

Interesting analysis:

Although much attention is given to sophisticated, zero-click spyware developed by companies like Israel’s NSO Group, the Italian spyware marketplace has been able to operate relatively under the radar by specializing in cheaper tools. According to an Italian Ministry of Justice document, as of December 2022 law enforcement in the country could rent spyware for €150 a day, regardless of which vendor they used, and without the large acquisition costs which would normally be prohibitive.

As a result, thousands of spyware operations have been carried out by Italian authorities in recent years, according to a …

Most of 2023’s Top Exploited Vulnerabilities Were Zero-Days

Posted on by

Zero-day vulnerabilities are more commonly used, according to the Five Eyes:

Key Findings

In 2023, malicious cyber actors exploited more zero-day vulnerabilities to compromise enterprise networks compared to 2022, allowing them to conduct cyber operations against higher-priority targets. In 2023, the majority of the most frequently exploited vulnerabilities were initially exploited as a zero-day, which is an increase from 2022, when less than half of the top exploited vulnerabilities were exploited as a zero-day.

Malicious cyber actors continue to have the most success exploiting vulnerabilities within two years after public disclosure of the vulnerability. The utility of these vulnerabilities declines over time as more systems are patched or replaced. Malicious cyber actors find less utility from zero-day exploits when international cybersecurity efforts reduce the lifespan of zero-day vulnerabilities…

Good Essay on the History of Bad Password Policies

Posted on by

Stuart Schechter makes some good points on the history of bad password policies:

Morris and Thompson’s work brought much-needed data to highlight a problem that lots of people suspected was bad, but that had not been studied scientifically. Their work was a big step forward, if not for two mistakes that would impede future progress in improving passwords for decades.

First, was Morris and Thompson’s confidence that their solution, a password policy, would fix the underlying problem of weak passwords. They incorrectly assumed that if they prevented the specific categories of weakness that they had noted, that the result would be something strong. After implementing a requirement that password have multiple characters sets or more total characters, they wrote:…
