A question for #infosec practitioners. I've found an abandoned AWS bucket from a very large company. It serves all the images & fonts in their billing emails. I defensively registered it to prevent an attacker from injecting malicious content into the emails I receive. Then I emailed their security.txt contact to inform them and offering to transfer it back (for free, obviously). Was that the right thing to do? Should I have waited for a response from them before securing the bucket?

I just wrote the following on a GitHub issue. I don't understand why people have not learned this yet: ⚠️ NEVER SEND POTENTIAL SECURITY ISSUES PUBLICLY. If the security issue is concrete, it also poses all the users at risk because the maintainers might not have time to act.

The massive push for software supply-chain integrity and transparency has left organizations struggling to secure their pipelines and manage vulnerabilities. Existing tooling doesn’t support supply chain security natively and requires users to bolt on critical features like signatures, provenance, and software bills of material (SBOM). Everything you need to know about securing the software supply chain.

The story of how I could steal credentials on Infosec Mastodon with a HTML injection vulnerability, without needing to bypass CSP. Everybody on our Twitter feed seemed to be jumping ship to the infose

Infosys has a lot to say about security You can check out their website for a lot of buzwords , but it’s clear from all the stock photos that they take security Very Seriously Indeed ™️. However, from what I’ve found recently, it seems that Infosys use the following Comprehensive Management-Endorsed Proficiently Driven Cybersecurity Strategy and Framework items: Don’t use AWS roles or temporary credentials for your developers Instead, use IAM user keys and give them all FullAdminAccess permissions Never rotate these keys and store them as plaintext in git Use these keys to protect what appears to be medical data about COVID patients Have someone publish those keys and the code in a public package to pypi Keep those keys active for days after leakage Make nonsensical pull requests to try and remove all references to the leak The Leak This morning I woke up to a very strange pull request on my pypi-data project.

Public listings have made sensitive data searchable due to misconfigured third-party services

Many of us use one-time passwords (OTP) regularly to log into different services. Most probably rely on Google Authenticator and similar tools. But what about building one by ourselves?

Announcing vulnerability management for Go, to help developers learn about known vulnerabilities in their dependencies.

The other day someone claimed a hostname on a domain I own and it took me a while to track down how. After a lot of digging around, trying to figure out how the hijack was accomplished, it turns out it was via GitHub Pages.

1. Buy expired NPM maintainer email domains. 2. Re-create maintainer emails 3. Take over packages 4. Submit legitimate security patches that include package.json version bumps to malicious dependency you pushed 5. Enjoy world domination.

If you need to verify the ID of the OAuth application, check the number at the end of the url like github.com/orgs/<org>/policies/applications/145909 coming from the github.com/organizations/<org>/settings/oauth_application_policy page.

Wow, @Zoom's decision to bypass the security settings of their customers in order to boost its marketplace demand is a bold move, to put it mildly. CISOs discovering this after the fact will be fuming.

Since #Log4j you've heard how OSS vulns impact most orgs, how OSS is underfunded & we need to do more to help, but did you know OSS security has improved drastically in the last 4 years? In 2017, 35% of OSS libs used had a known flaw. In 2022 it's < 10% veracode.com/state-of-softw…

Federal government memo: "Consistent with the practices outlined in SP 800-63B, agencies must remove password policies that require special characters and regular password rotation from all systems within one year of the issuance of this memorandum." Yes!

The federal government just dropped a 29-pg memo laying out its "transition to a zero trust approach" A few surprises: ✴️ there's more in it than just zero-trust ✴️ it goes beyond what most orgs do today I read the whole thing so you don't have to... bastionzero.com/blog/i-read-th…

"Securing the (open source) software supply chain" naturally focuses attention "upstream" in the supply chain. And there is so much to do _downstream_ in how we assemble and operate software more securely. Improvements downstream don't need to wait on investments upstream.

Looks like the AWS CDK is broken because the dependency on colors.js which has a totally hilarious bug: github.com/aws/aws-cdk/is… It shows "LIBERTY LIBERTY LIBERTY".
