When and why to stray from Chrome, Edge, or Firefox, some programs and extensions to support your Internet experience, and the increasing complexity of the dangers of going online.
1) HTML5 and new web standards like Content Security Policy and cross-origin resource sharing improve security by enabling enforcement of policies like script isolation in the client instead of through server-side filtering.
2) Script injection vulnerabilities like cross-site scripting can be solved using these new client-side techniques rather than incomplete server-side simulations.
3) Mashups can be made more secure by using CORS to retrieve validated data instead of injecting code, and postMessage with isolated iframes to communicate with legacy APIs.

The web has radically changed and improved over the last 15 years. Unfortunately, the CMS technology behind a website has not. Editors still find themselves filling out complex form fields and hitting preview buttons. Do you know a single person who LIKES to work with a CMS? Problem is, currently available CMSs are known for terrible usability, ancient technologies, high maintenance – and they constantly face serious security threats. Commercial CMS are just more expensive - but not better in any way. Learn about the next generation of content management solutions, about new approaches like headless CMS and JAMstack, new technologies like ReactJS and what it takes to make your website run like it's 2019, not 2003.

In today’s world, it seems inconceivable that any business would operate without some form of online presence. And although many companies have realised the power of social media by using it as a marketing platform to present their businesses to the world, that’s no longer enough to set you apart from the competition. That’s because almost all enterprises now have a social presence – no matter how small. To really set yourself apart from the competition, the least you need is a website that displays your company information and that tells your potential customers who you are and what you do. That’s where a custom website designed and developed for your niche business sets you apart from the crowd.
Web 1.0 focused on commerce while Web 2.0 emphasizes user participation and contribution. The principles of Web 2.0 include customization for individuals, leveraging the "long tail" of less popular content, and harnessing collective intelligence by allowing users to add value through tagging, reviews, and editing. Web 2.0 applications also focus on specialized databases and perpetual beta releases with frequent updates.

Phishing with Super Bait
Jeremiah Grossman, Founder and CTO, WhiteHat Security
The use of phishing/cross-site scripting (XSS) hybrid attacks for financial gain is spreading. ItÕs imperative that security professionals familiarize themselves with these new threats to protect their websites and confidential corporate information.
This isn't just another presentation about phishing scams or cross-site scripting. WeÕre all very familiar with each of those issues. Instead, weÕll discuss the potential impact when the two are combined to form new attack techniques. Phishers are beginning to exploit these techniques, creating new phishing attacks that are virtually impervious to conventional security measures. Secure sockets layer (SSL), blacklists, token-based authentication, browser same-origin policy, and monitoring / take-down services offer little protection. Even eyeballing the authenticity of a URL is unlikely to help.
By leveraging cross-site scripting, the next level of phishing scams will be launched not from look-alike web pages, but instead from legitimate websites! This presentation will demonstrate how these types of attacks are being achieved. We'll also demonstrate the cutting edge exploits that can effectively turn your browser into spyware with several lines of JavaScript. And, we'll give you the steps you need to take to protect your websites from these attacks.

In essence, these findings underscored the holistic approach needed for sustainable growth in the clothing business, emphasizing the importance of product management, marketing strategies, customer experience, and operational efficiency.
2. Google Chrome Extensions
• Extensions are small software programs that customize the browsing
experience. They enable users to tailor Chrome functionality and behavior
to individual needs or preferences. They are built on web technologies
such as HTML, JavaScript, and CSS.
• An extension must fulfill a single purpose that is narrowly defined and
easy to understand. A single extension can include multiple components
and a range of functionality, as long as everything contributes towards a
common purpose.

3. Google Chrome Extensions

6.) Can my extension make changes to the start page, homepage, and new tab
settings?
Yes. If the purpose of your extension is to modify one narrow function of the browser
(either the start page, homepage or new tab page, for example), and it does only that,
then it would be compliant with the single-purpose policy.
Additionally, if the purpose of your extension is limited to one focus area or subject
matter, then you can have various functions related to that one area or subject matter,
including changes to start page, homepage and new tab page.
As of July 1, 2017, … If your extension modifies one of these functions, it must use the
Settings Overrides API.
4. Browser Extensions
• Extensions are installed within the files for your browser application.
• Extensions aren’t an application all on their own — their code runs as part
of your browser. Because your browser is already a trusted application, it’s
hard for antivirus software to catch malicious extensions.

18. lnkr: The New Malicious
Browser Extensions
Campaign Spreading
Across the Net
19. lnkr
https://securitytrails.com/blog/lnkr-malicious-browser-extension
This campaign targets legitimate and semi-legitimate browser extensions:
• cloning
• injecting with malicious code
• distributing them across the Google Chrome Store.
The goal is to inject scripts into web pages currently browsed by the users, to redirect them to
several websites such as lnkr.us and lnkr.fr that seem to be part of this malware campaign, as they
appear to be fully controlled by the attackers.

https://securitytrails.com/blog/lnkr-malicious-browser-extension
Some of the C2 communications masquerade and are
promoted as analytics opt-out requests, explaining to the
users that the ads are used to support the development of
these extensions. This isn’t true: the advertising revenue
doesn’t go to the real extension developers at all.

Timeline 1
February 5, 2019: installed SpeakIt!, 0.3.10, on one VM and the latest version of Hover Zoom, 6.0.40, on another
VM. No browsing activity data collection at the time of installation.
February 15, 2019: We observed each extension perform an automated Chrome extension update. Hover Zoom
was updated to version 6.0.41, and SpeakIt! to version 0.3.11. No browsing activity data collection at the time of
installation.
March 1, 2019: We observed each extension perform an automated Chrome extension update. Hover Zoom was
updated to version 6.0.42, and SpeakIt! to version 0.3.12.
March 1, 2019: Seconds after the update, GET request to cr-b.hvrzm.com (Hover Zoom) or cr-b.getspeakit.com
(SpeakIt!), with a response payload containing a data collection instruction set. Following the GET request, all
subsequent user browser activity data was collected and sent via a POST request to cr-input.hvrzm.com (Hover
Zoom) or cr-input.getspeakit.com (SpeakIt!).

Timeline 2
May 22, 2019: We installed SpeakIt! version 0.3.21 (the latest version at the time) on a VM located in a different
geographic region and at a different hosting provider.
June 1, 2019: SpeakIt! was automatically updated to version 0.3.22. After the update, we did not observe any
browsing activity data collection.
June 15, 2019: We observed an automatic update to SpeakIt! version 0.3.23.
June 15, 2019: Seconds after the update, we observed a GET request to cr-b.getspeakit.com. This GET request’s
response payload contained the data collection instruction set. Following this request, all subsequent user
browser activity data was collected and sent via a POST request to cr-input.getspeakit.com.
We repeated this experiment six times, under numerous scenarios; each time we obtained the same result. In
the past, similar tactics have been used to avoid detection of data collection. As of May 9, 2019, more than 2.29
million people use Hover Zoom and SpeakIt!.

Using a browser with a Party Y extension, we visited various sample file types, including zip and SQL database
files.
When visiting the zip file, the browser downloaded the file into the file system. It did not load them directly in
the browser. As a result, we did not observe the transmission of the zip URL to a third-party hostname.
However, the SQL files were loaded in the browser and the URL of our SQL files was transmitted to cr-
input.hvrzm.com. Three hours after it was collected by the Party Y extension, we observed a third-party visit to
our SQL file:
184.72.115.35 – – [18/May/2019:12:50:27 +0000] “GET /dataspii-sql-50000rows.sql HTTP/1.1” 200 4393501

38. Before Installing an extension…
• Double-check that the extensión you’re installing is the one you really want
• Malicious with same name
• Does the developer seem legitimate?
• Have they published other extensions?
• Do they have a website?
• Does the extension clearly explain what it will do in your browser?
• Is it recommended in reviews?
• Who are the reviews by?
• Anonymous commenter?
• New Site?
• Reputable tech Blogger
39. Before Installing an extension…
• Legitimate developers can certainly make typos, but a description that’s
riddled with spelling errors, sentences that don’t make sense, or a very
vague explanation that glosses over what the extension does, should be a
red flag.
• Be wary of words that are repeated an extreme number of times —
developers of malicious extensions may repeat keywords so that the page
shows up more readily in a search
40. But…
• Extensions can be sold
to new developers
• Malicious actors can
hijack the accounts of
legitimate developers
and push malicious
updates to safe,
previously installed
extensions
41. Block Chrome Extensions using Google
Chrome Group Policy Settings
https://www.technospot.net/blogs/block-chrome-extensions-using-google-chrome-group-policy-settings/
If you have system admin privilege, Launch the Group Policy Editor
and Navigate to:
Computer Configuration > Administrative Templates > Google > Google
Chrome.
Here look for folder name Allowed extensions. Here you have two configuration
files one which lets you whitelist or always allow an extension and another
which blocks the extension to be installed in Chrome Browser.
42. Define Chrome browser policies on managed
computers

• You can define device-level policies, which will be applied regardless of
whether people are using the Chrome browser or logged into an account.
• You can also set user-level policies for the operating system, which will be
applied when certain users logon to a device.
• You can make it mandatory to apply policies that users cannot change, or set
default preferences that users can change.
