How chaining the blocks protect against altering data?

I am confused with the block chaining, as i know a block header contains a reference to the previous block header hash with the merkle root and other fields. This header hash is related (computed) to the header and not including the block of transactions, so if the header is tampered the chain will fail. I understood that, but if the transactions in the block are edited, it will not change the header hash only if the merkle root is re-calculated.

My question is when a node receive a block, how it verifies it (just rehashing the header, or recalculating merkle root first then rehashing the header)?

D8: Altering Views Exposed Form Elements and their Associated Labels

I have a series of Views Exposed Forms across a Drupal 8 website. My goal is to generate unique template suggestions so I can theme each individual input and their labels differently as needed.

Here is my current approach. Placed into theme.theme. I’ve hit a brick wall.

function HOOK_form_views_exposed_form_alter(array &$  form, FormStateInterface $  form_state, $  form_id) {     $  form['#attributes']['twig-suggestion'] = $  form['#id']; }  function HOOK_theme_suggestions_input_alter(&$  suggestions, array $  variables) {     $  element = $  variables['element'];      if (isset($  element['#attributes']['twig-suggestion'])) {       $  suggestions[] = 'input__' . $  element['#type'] . '__' . $  element['#attributes']['twig-suggestion'];     } }  function HOOK_theme_suggestions_form_element_label_alter(&$  suggestions, &$  variables, $  hook) {     $  element = $  variables['element'];      if (isset($  element['#attributes']['twig-suggestion'])) {       $  suggestions[] = 'label__' . $  element['#attributes']['twig-suggestion'];     } } 

All input and label [#attributes] are null via Kint.
Here are the URLs I have referenced for background:




How to detect malicious actor altering DNS responses?

I am trying to detect what is causing my DNS to return fake IP addresses for domains like apple, orange, etc. which obviously don’t exist.

If I do following on my Windows machine:

  • ipconfig /flushdns – flush DNS cache
  • ping apple – invoke DNS query
  • ipconfig /display – see DNS cache

the ping command doesn’t fail and I can see DNS entry in the output.

I tried visiting http://apple on both Windows machine and Android machine (which I checked are both using the same DNS config), my Android machine can’t find the domain.

My question: What could possibly be acting maliciously between Windows’ DNS client and the DNS server, or how could I go about finding where the malware is installed?

Note: my Windows machine is connected to router via Ethernet, while Android device uses Wi-Fi.

Can i run “DemoteNewsArticle” & “CommentsEnabled” commands without altering the ModifiedBy and Modified fields and without sending users alerts

I am working on a SharePoint online classic team site. and from time to time I run these remote power-shell commands:-

1- To un-post a modern page from being shown as News:-

$  clientSidePage = Get-PnPClientSidePage -Identity "TEST-PAGE.aspx" $  clientSidePage.DemoteNewsArticle() 

2- To disable comments on a modern page:-

$  cred = Get-Credential   Connect-PnPOnline -Url hhttps://* -Credential $  cred   Set-PnPClientSidePage -Identity "test-page.aspx" -CommentsEnabled:$  false 

now the first command will cause the ModifiedBy + the Modified fields to be updated. where the second command will cause the ModifiedBy field to be updated. also both commands will cause users’ alerts to be sent (when users set the alert on every change).

so can i modify my above 2 commands, so the ModifiedBy and the Modified fields will not get updated? also to prevent users’ alerts from being sent?
