Another disadvantage of using extensions in the developer console is that it is not suited for webpage scanning,
as a website could be potentially malicious. Then an online third party scan could be the only secure option left
or using a special browser like Bobby's Malzilla for instance with a specific VM.

Malware should be studied on a stand alone offline device, one not being connected to the Internet.

So there are a couple of online scanners left.
For instance, this one: https://www.web-malware-removal.com/website-malware-virus-scanner/

Checked a site and is OK, but has some server related issue:

But before you start, study a particular subject - like for instance the ins and outs of DOM-XSS sinks and sources.
Also read from stackoverflow and other resources. A researcher/error-hunter should read-inform-read-inform
to get familiar with all the aspects of what he or she is doing.

Whenever you are into a form of particular specific scanning,
be ready to make yourself familiar with resources, for instance by using spreadsheets.

For DOM-XSS sinks and sources like these examples:
https://docs.google.com/spreadsheets/d/1Mnuqkbs9L-s3QpQtUrOkPx6t5dR3QyQo24kCVYQy7YY/edit#gid=0

Above particular spreadsheet is meant to work on a specific native jQuery version.

Next to a website address (URL or uri) one should also always check the corresponding IP (could be several) for that particular website.

IP could be on a banlist, check: https://www.dnsqueries.com/en/check_banned_ip.php
Also check here: http://www.brightcloud.com/tools/url-ip-lookup.php
or here: https://www.threatcrowd.org/ip.php?ip=216.58.208.33 (random example)
or here: https://hetrixtools.com/  or  http://webyzer.net/ip/181.224.138.136 (random example)
or here: https://www.abuseipdb.com/check/46.126.113.90 (random example)
or here: https://www.ip-tracker.org/lookup.php?ip=102.66.223.235 (random example)

Also at VT we could find a lot of information just giving in and query for a particular IP.
And where I also regularly report: https://ip-46.com/  IP v4 v6 Intelligence, (fine resources  ;) ),

Good hunt,

Before visiting a Magento wenshop website, it is a good idea to scan it at magereport.com.

Maybe some webshops might have been splendidly deveoped at first, but weren't updated in time:
random example: https://www.magereport.com/scan/?s=https://hoegl.com/  (outdated Magento version)

There are always threats around the corner: https://www.ncsc.gov.uk/news/guidance-for-retailers-to-prevent-websites-becoming-black-friday-cyber-traps

We all may have used these well-known free online website malware scanners at some moment in time:
Re: https://geekflare.com/online-scan-website-security-vulnerabilities

This is a not so well-known website privacy scanner: https://themarkup.org/blacklight?url=

For those on tor looking for "bad relays": https://metrics.torproject.org/  also: https://intelx.io/ (blocked to be used inside tor)

Enjoy, my good friends, enjoy,

Check your Word Press plug-ins for vulnerability and latest updates.

55,9% of Word Press CMS websites are being hacked through vulnerable plugins.

Hackers can run all sorts of malicious activities like stealing data, run unwanted ads, defacing websites etc.
Furthermore this may redirect visitors, leads to injected spam and content, installed malcreations (malware),
creation of roque admin accounts, all wreaking havoc on website revenues and your online reputation.

Also various bad may happen with bad configuration seen after install, that means
'user enumeration' not set as disabled, and also 'directory listing' not set as disabled.

There are over 50.000 Word Press plugins and new ones created every day,
and also some left by their developers (left vulnerable code).

Those attacked recently Duplicator, ThemeGrill Demo Importer,  Profile Builder, various WooCommerce plugins, ThemeREX,
Async JS, Modern Events Calendar, Google Maps plug-in. (info source - malware dot com dot blog).

Do a quick and dirty at https://hackertarget.com and perform a free Word Press security scan there.
Do a passive scan: https://hackertarget.com/wordpress-security-scan/

Another low-impact scanner: http://wprecon.com/

Go on testing and analyzing with a robots.txt tester and validator:
https://www.websiteplanet.com/webtools/robots-txt/?url=forum.avast.com

No results for this one, because the forum is not indexable; only links to be followed.

But here 1 error and 8 warnings: https://www.websiteplanet.com/webtools/robots-txt/?url=wordpress.com

Good informative info for website developers,

The following test page should give you an error inside the browser:
https://pinning-test.badssl.com/

This site is preloaded with a bad HPKP pin.
Checks your https-security is OK. No guv-snooping certs implemented?

Excellent test: https://www.ssllabs.com/ssltest/analyze.html?d=pinning-test.badssl.com

And for other online scanners: https://geekflare.com/ssl-test-certificate/

OK inside your browser? Re: https://www.howsmyssl.com/

In order to add Clickjacking protection, either 'frame-ancestors', 'frame-src' or 'child-src' should be strictly defined.
'frame-ancestors' directive, is more powerful and flexible than the X-Frame-Options, and considered necessary in order to properly prevent Clickjacking attacks. Can you restrict 'frame-ancestors' to 'none' or 'self'?

Hi folks on the avast support forums. From me best wishes for the coming New Year 2022.
May you stay free of any mishap both offline as well as online.

This time my question was: ""Who is behind CloudFlare?".

Whenever you do an IP look-up at a CloudFlare protected website, like for instance shodan.io,
CloudFlare may block you as a visitor. This is whenever they cannot fully identify you.
You cannot go there anonymously. No tor-users are allowed on their platform either,
even when you aren't into any mischief.
You are banned until you can give proof of who you really are as a human being (real IP).

In such cases it can be interesting to know who is behind a certain CloudFlare reversed proxy address.
You can look it up at: https://securitytrails.com/list/ip/104.18.12.238  (example for shodan.io) (random example by me, pol).

Mind to do your look-ups at securitytrails.com not from behind a proxy, else you also meet with their endless captcha,
even when you are not a bot and strictly a human anonymous. They also are CloudFlare driven.

It is a pity the extension to see whether one was safe from NSA spoofing on a particular website,
is now no longer available as a Google's or cromium extension.
Their new extension and api restricting settings will make blocking etc. much harder.
Coming to a browser near you in the forecoming months, I think May 2022.

A couple of extension developers have already thrown the towel into the developer's ring.
Well the going gets narrow, as some clamps seem to be coming down.

It is a pity really and actually a shame for the last bit of end-user-autonomy.
I use a London-based in-browser proxy by Digital Ocean in the browser
and have experienced above scenario various times.
