Security – How can an LN node acquire in-depth liquidity? Is there a systemic risk?

I once heard that LN can support channels with two funds. It does not seem so complicated, but at present I do not know any LN wallet that supports the creation of two-fund channels.

By the way, I'm also worried about security: will dual-funded channels introduce systemic risks / attack vectors? For example, if an attacker could already make a 51 percent double-spend attack, could he use the incoming liquidity to multiply his profit?

Are there any security risks in accepting HTTP / 0.9 style GET requests? (eg "GET / r n")

I write a web server for fun and add support for HTTP / 1.0. The main reference I use is RFC 1945 => Hypertext Transfer Protocol – HTTP / 1.0.

In Section 5.1 of the RFC, I learned that HTTP requests require a single row, a GET method, and a URI (for example, GET / r n). The RFC calls this a simple request.

Is there a security risk in modern HTTP servers to accept and answer a simple request? If so, what are the risks?

Internet security from SendMail

I'd like to know if there's a way to make sure emails sent by Mathematica are encrypted Transit and at rest,

Use Gmail or Yahoo account servers for Sendmail"I really want to know more details about the security of e-mail payloads sent by SendMail[] from both Mathematica and Mathematica Online accounts (Wolfram1 / Open Lab / Dev), e.g. About PGP, TLS, MFA, and more.

Links, documents or undocumented notes would be helpful.

Disclosure – How do you deal with a white hacker claiming a security hole?

To answer any of your questions:

1. Basically, how should we proceed or should we even?

I recommend to continue. You get valuable information that can be used immediately to improve the security of your business. They did not tell us what the researcher sent you, but they either have a description of the vulnerability or methods to reproduce. To continue, you need from them:

  • A description / attack scenario of the vulnerability found. Why is this a problem? What allows an attacker to do exactly what he should not do? What is the worst case / severity of the finding?

  • Reproduction steps. What steps could you give each engineer so that he can reproduce the error each time?

  • What the hacker is looking for in return. As mentioned, it may be that permission is given to publish the determination after the correction or after the money.

  • You may or want to receive correction instructions, risk assessments, etc. from the researcher.

VERY IMPORTANT: Make it clear to the researcher that you expect the issue to be kept confidential until the problem is resolved. You can use a correction window, eg. You can publish and publish articles if the problem is not resolved within 60 days. This is common practice and should be acceptable to most companies with a strong security record.

2. What is the general expectation of a white hacker?

Depends on the researcher, but he will probably want permission to publish the result as soon as it has been fixed, as well as a financial reward. The awards are based on the overall severity and scope of the bounty program. Hackerone, a large bug bounty platform, has a matrix that suggests payouts relative to the size of the company / bounty program: Determining the payout price is a subtle art. I recommend that you search Hackerone or other bug bounty platforms for similar errors and base your payoff on what other companies are paying for the same problem.

Again, researchers' common expectation is that they can publish the finding in a given time, regardless of whether it has been remedied by then. 60 days is common, but I would not agree to a time span if you're not sure your business can deliver in this window. After the issue is resolved, the hacker wants to verify that the fix has been implemented correctly.

3. How to validate?

Use the steps the hacker gave you. They should be clear enough that every engineer can follow the steps exactly and reproduce the mistake. If there are problems here, you can return to the researcher and get some clarity. It is the responsibility of the researcher to provide the company with reproduction steps that describe and identify the error.

Once the problem is resolved, you can invite the researcher to review the fix and ensure that it has been completely patched.
