Security research on Private Cloud Compute

Private Cloud Compute (PCC) fulfills computationally intensive requests for Apple Intelligence while providing groundbreaking privacy and security protections — by bringing our industry-leading device security model into the cloud. In our previous post introducing Private Cloud Compute, we explained that to build public trust in the system, we would take the extraordinary step of allowing security and privacy researchers to inspect and verify the end-to-end security and privacy promises of PCC. In the weeks after we announced Apple Intelligence and PCC, we provided third-party auditors and select security researchers early access to the resources we created to enable this inspection, including the PCC Virtual Research Environment (VRE).

Today we’re making these resources publicly available to invite all security and privacy researchers — or anyone with interest and a technical curiosity — to learn more about PCC and perform their own independent verification of our claims. And we’re excited to announce that we’re expanding Apple Security Bounty to include PCC, with significant rewards for reports of issues with our security or privacy claims.

Ransomware Tool Matrix

This repository contains a list of the tools used by each ransomware or extortion gang.

As defenders, we should take advantage of the fact that many of the tools used by these cybercriminals are often reused.

We can threat hunt, deploy detections and block these tools to deny adversaries the ability to launch intrusions.

Mozilla is an advertising company now

Mozilla has acquired Anonym, a [blah blah blah] raise the bar for the advertising industry [blah blah blah] while delivering effective advertising solutions.

Anonym was founded with two core beliefs: [blah blah blah] and second, that digital advertising is critical for the sustainability of free content, services and experiences.

As we integrate Anonym into the Mozilla family, we are excited about the possibilities this partnership brings. While Anonym will continue to serve its customer base, together, we are poised to lead the industry toward a future where privacy and effective advertising go hand in hand, supporting a free and open internet.

Anonym was founded in 2022 by former Facebook executives Brad Smallwood and Graham Mudd. The company was backed by Griffin Gaming Partners, Norwest Venture Partners, Heracles Capital as well as a number of strategic individual investors.

no-defender

A slightly more fun way to disable windows defender.

There's a WSC (Windows Security Center) service in Windows which is used by antiviruses to let Windows know that there's some other antivirus in the hood and it should disable Windows Defender.

This WSC API is undocumented and furthermore requires people to sign an NDA with Microsoft to get its documentation, so I decided to take an interesting approach for such a thing and used an already existing antivirus called Avast. This AV engine includes a so-called wsc_proxy.exe service, which essentially sets up the WSC API for Avast.

With a little bit of reverse engineering, I turned this service into a service that could add my own stuff there.

Foxit PDF “Flawed Design” Exploitation

Check Point Research has identified an unusual pattern of behavior involving PDF exploitation, mainly targeting users of Foxit Reader. This exploit triggers security warnings that could deceive unsuspecting users into executing harmful commands. Check Point Research has observed variants of this exploit being actively utilized in the wild. Its low detection rate is attributed to the prevalent use of Adobe Reader in most sandboxes or antivirus solutions, as Adobe Reader is not susceptible to this specific exploit. Additionally, Check Point Research has observed various exploit builders, ranging from those coded in .NET to those written in Python, being used to deploy this exploit.

Lethal Injection: How We Hacked Microsoft's Healthcare Chat Bot

We have discovered multiple security vulnerabilities in the Azure Health Bot service, a patient-facing chatbot that handles medical information. The vulnerabilities, if exploited, could allow access to sensitive infrastructure and confidential medical data.

All vulnerabilities have been fixed quickly following our report to Microsoft. Microsoft has not detected any sign of abuse of these vulnerabilities. We want to thank the people from Microsoft for their cooperation in remediating these issues: Dhawal, Kirupa, Gaurav, Madeline, and the engineering team behind the service.

The first vulnerability allowed access to authentication credentials belonging to the customers. With continued research, we’ve found vulnerabilities allowing us to take control of a backend server of the service. That server is shared across multiple customers and has access to several databases that contain information belonging to multiple tenants.
