How can I prevent an iframe displaying an email to load images and other email trackers?

阅读更多关于 How can I prevent an iframe displaying an email to load images and other email trackers?

问题 We have a web admin panel in which the agents can see conversations with customers. Those conversations are the result of importing normal emails thru an IMAP connection. We grab the "untouched" mailbox files and we store them in a database. Then we post-process the files to index by "from", "to", "date" and so on and so forth. Up to here, okey. We can seek all the emails involved with a client and render them at will. Then when the agent looks for a customer in the web admin panel and opens

问题 We are testing with SOAP against the test url - https://apitest.authorize.net/soap/v1/Service.asmx Curious if this is the Sandbox environment with TLS 1.0 and 1.1 disabled? 回答1: From an email from Authorize.Net last year: Dear Authorize.Net Partner: As you may be aware, new PCI DSS requirements state that all payment systems must disable early TLS by 2018. In preparation for this requirement, Authorize.Net plans to disable TLS 1.0 and TLS 1.1 on the following dates: Sandbox: April 30, 2017

Sandboxing in .net core

阅读更多关于 Sandboxing in .net core

问题 I was wondering how I can achieve sandboxing in .net core, since appdomains are not supported in .net core for this. Also, I can't use Virtualization or docket containers because these things are not available on my target machine. 回答1: Per .NET Core docs, looks like your options are a bit limited. Free of problematic tech. .NET Core doesn’t include certain technologies we decided to discontinue because we found them to be problematic, for instance AppDomain and sandboxing. If the scenario

Sandbox JVM to secure server from untrusted sources

阅读更多关于 Sandbox JVM to secure server from untrusted sources

问题 How can protecting my server from malicious activity when accepting and executing uploaded, untrusted code? The users should be able to implement my interface and given data, perform some calculations and return data. No I/O operations are required and certainly no thread/process manipulation or other tomfoolery. Using the java.policy file it is possible to deny everything (by granting nothing). $ cat test.policy grant { }; Using this policy file, operations not granted will cause a security

问题 I am making an app where it downloads mobileconfig from my server to my ios app. And I've created a server running background and used openUrl to open it in the safari so user can install the profile. But it only works in the simulator but not on my device. [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"http://localhost:12345/file.mobileconfig"]]; where file.mobileconfig is downloaded in the root(localhost). A.I ve implemented this solution: Open .mobileconfig file saved in

Is there an alternative to NSFileCoordinator for opening related files in a sandbox?

阅读更多关于 Is there an alternative to NSFileCoordinator for opening related files in a sandbox?

问题 This is a follow-up to Access sidecar files in a Mac sandboxed app. Though not covered in the answer there, the Apple docs teach us that to access a "related file" we must use an NSFileCoordinator for access (ref). This is a little heavy for my needs, and poses an architectural problem, since the actual file access is in my back-end code, away from the reaches of the Apple library facilities. I don't want to have to use the NSFileCoordinator for obtaining the related file's content, if I can

How to do Binary instrumentation of syscall brk ? (x86-64 Linux) (maybe valgrind?)

阅读更多关于 How to do Binary instrumentation of syscall brk ? (x86-64 Linux) (maybe valgrind?)

问题 I'd like to instrument syscall brk (and other calls but this in first order, it's most important to me) in given binary (preferably on actual syscall/sysenter level (x86-64 and x86) of making sys_brk call). Main goal: A part of sandbox which gives fixed amount of memory to jailed process So, I'd like to get rid of brk system calls (and most preferably others in next order) and simulate memory allocations under fixed limit . Fixed limit is memory space, available to program. (You can think
