A semi-tethered jailbreak is one that allows a handset to finish a boot cycle when being pwned, however jailbreak extensions won't load till a laptop-based jailbreak application is deployed over a physical cable association between the device and also the computer in question.
Semi-tethered jailbreaks aren't as difficult as tethered jailbreaks as a result of you'll be able to power cycle your device and expect to use it commonly thenceforth, like creating phone calls and causing text messages. On the opposite hand, jailbreak tweaks won't initialize on the freshly-booted device and jailbreak-based apps like Cydia and Filza can merely crash on launch them till the device is shod back to a jailbroken state.
Just as the name implies, a semi-'tethered' jailbreak necessitates a physical cable association between the device and also the laptop once running the jailbreak tool to patch the kernel and reinitialize the jailbroken state, however the nice issue here is that you simply will still access important core smartphone practicality in an exceedingly pinch after you don't have a laptop near .
The spic-and-span checkra1n jailbreak tool for macOS (and before long Windows) could be a prime example of a semi-tethered jailbreak, and may pwn A7-A11-equipped devices as previous because the iPhone 5s and as new because the iPhone X.

Out-of-band SQL injection occurs when an attacker is unable to use an equivalent channel to launch the attack and gather results. ... Out-of-band SQLi techniques would believe the database server's ability to form DNS or HTTP requests to deliver data to an attacker. Out-of-band SQL injection is not very common, mostly because it depends on features being enabled on the database server being used by the web application. Out-of-band SQL injection occurs when an attacker is unable to use the same channel to launch the attack and gather results.
Out-of-band techniques, offer an attacker an alternative to inferential time-based techniques, especially if the server responses are not very stable (making an inferential time-based attack unreliable).
Out-of-band SQLi techniques would rely on the database server's ability to make DNS or HTTP requests to deliver data to an attacker. Such is the case with Microsoft SQL Server's xp_dirtree command, which can be used to make DNS requests to a server an attacker controls; as well as Oracle Database's UTL_HTTP package, which can be used to send HTTP requests from SQL and PL/SQL to a server an attacker controls.
