Replit is the most secure place to vibe code. Today, we're making it dramatically easier to use the Security Center to understand your security posture across all Replit projects in your business. We’re also making it possible to remediate urgent security holes, such as active critical vulnerabilities on multiple published projects, in seconds. You can reach the Security Center from the Replit Homepage, or your Settings. When you land there, the first thing we want to answer is simple: which of my projects are actually at risk right now? Start with what's urgent At the top of Security Center,…
An amazing security lapse just occurred: a journalist was accidentally included on a group chat via Signal to discuss sensitive war plans. This was wrong on so many different levels—read the article; it’s one of the msot amazing things I’ve ever read—but what I want to talk about is what “secure” means. Let’s start with what Signal is. It bills itself as a “simple, powerful, and secure messenger”. It works more or less like any other text/voice/video communication platforms, but it’s strongly end-to-end encrypted. But is it really “secure”? That depends on your definition. The first layer up…
Posted by Chrome Root Program Team Secure connections are the backbone of the modern web, but a certificate is only as trustworthy as the validation process and issuance practices behind it. Recently, the Chrome Root Program and the CA/Browser Forum have taken decisive steps toward a more secure internet by adopting new security requirements for HTTPS certificate issuers. These initiatives, driven by Ballots SC-080, SC-090, and SC-091, will sunset 11 legacy methods for Domain Control Validation. By retiring these outdated practices, which rely on weaker verification signals like physical…

Email encryption and authentication are modern security techniques that you can use to protect your emails and their content from unauthorized access. Everyone, from individuals to business owners, uses emails for official communication, which may contain sensitive information. Therefore, securing emails is important, especially when cyberattacks like phishing, smishing, etc.

I'm still on my self-hosting kick as of late, while also questioning my life choices around hosting my own git forge. The last week or so has included what appears to be a DDoS attack rather than some coordinated scraping effort by a sketchy LLM company. Open source will prevail, even if I'm being stubborn about giving in and setting up Anubis. WordPress has been its own other adventure, but this isn't meant to be a post about those security caveats. I'll save those for another week. The current dilemma is that I'm far from home, ~30 hours away up in Rhode Island. I'm sitting at Audrey's…
Lessons from building an agentic software security strategy at PalantirIntroductionPalantir’s Product Security Team began experimenting with agentic AI across a variety of security workflows over a year ago. By the time Anthropic launched Project Glasswing, we were already using an internal multi-agent review harness with AI security agents focused on different areas of security expertise. Anthropic’s Mythos model and OpenAI’s cyber program helped to accelerate that work.Today, our team has operating capabilities for multi-agent source-code review, analyst-directed vulnerability hunting,…
Or how to make naïve hosters shut down your victim’s server. Do you want to bring down your victim’s game servers? Do they host their game servers on cheap VPSes at hosters who are not that experienced with networking? Is running an actual DoS against the server too expensive and illegal for you? Just grab a server for yourself from a questionable hoster with IP address spoofing allowed on their network. Next run a port scan using nmap (man page) with a spoofed source address (-S or -D for multiple decoys) using your victim’s IP address(es). As the target of the port scan choose a university…
This post is the second in a series about logging and audit trails from a security perspective. For the first post in the series, see Lessons in Logging: Chopping Down Security Risks Using Audit Trails If you’re looking to level up your security practices, logging is a good place to focus your attention. Just as logging is a core pillar of observability, comprehensive audit trails are a core pillar of a strong security program. Logs and audit trails are separate but overlapping concepts, and most companies can improve their security posture by investing in this area.
I work on homomorphic encryption (HE or FHE for “fully” homomorphic encryption) and I have written a lot about it on this blog (see the relevant tag). This article is a collection of short answers to questions I see on various threads and news aggregators discussing FHE. Facts If a service uses FHE and can respond to encrypted queries, can’t the service see your query? How is it possible to operate on encrypted data without seeing it?
This post is the first in a series about logging and audit trails from a security perspective. For the next post in the series, see Lessons in Logging, Part 2: Mapping Your Path to a Mature Security Program with Logs and Audit Trails At Latacora, we bootstrap security practices. We partner with companies that frequently have minimally developed security programs, work with them to figure out the right security practices for their current size, and then help them evolve and scale those practices as their business matures.
AI security is an engineering problem. That means defined security requirements, enforceable controls, named owners and evidence that protections work. As AI becomes more capable, the industry must accelerate security engineering, broaden access to defensive tools and share what works faster. Technology Changes, Security Fundamentals Endure The internet and cloud computing changed how software operates, […]
Posted by Chrome Secure Web and Networking Team Today we're announcing a new program in Chrome to make HTTPS certificates secure against quantum computers.

One year from now, with the release of Chrome 154 in October 2026, we will change the default settings of Chrome to enable “Always Use Secure Connections”. This means Chrome will ask for the user's permission before the first access to any public site without HTTPS. The “Always Use Secure Connections” setting warns users before accessing a site without HTTPS Chrome Security's mission is to make it safe to click on links. Part of being safe means ensuring that when a user types a URL or clicks on a link, the browser ends up where the user intended. When links don't use HTTPS, an attacker can…

Recently I've been looking into securing my laptop a bit. By default, every single program has access to everything: filesystem, network, other programs. First, I started looking into Firejail. It allows specifying paths the program can access, as well as the network and other special things. It's not bad and I used it for a while. What I don't like about Firejail is that it's setuid: it runs as root, sets up the sandbox, then starts the program that is passed as an argument. If there is a problem in Firejail then it can even extend the blast radius. Then I learned about Landlock. It is…
