🦑What is Capture the Flag - CTF ?
#FastTips

-CTF’s (capture the flag) are computer security/hacking competitions which generally consist of participants breaking, investigating, reverse engineering and doing anything they can to reach the end goal, a “flag” which is usually found as a string of text.


-DEF CON hosts what is the most widely known and first major CTF, occuring annualy at the hacking conference in Las Vegas. Many different competitions have branched off since then, and numerous ones are available year round. One of the best places to see when CTFs are being scheduled is ctftime, an active website with calendars and team rankings.

🦑Finding a CTF :

If you ever wanted to start running, you were probably encouraged to sign up to a 5k to keep focused on a goal. The same principle applies here: pick a CTF in the near future that you want to compete in and come up with a practice schedule. Here are some CTFs that we can recommend:


1) PicoCTF and PlaidCTF by CMU

2) HSCTF is made for high school students

3) Ghost in the Shellcode (GitS)

4) CSAW CTF by NYU-Poly

5) UCSB iCTF is for academics only

6) Defcon CTF

According to Microsoft, the execution policy is part of the security strategy of PowerShell. It determines whether you can load conguration les (including your PowerShell prole) and run scripts, and it determines which scripts, if any, must be digitally signed before they will run. It should be noted that Microsoft has gone on record saying that the ExecutionPolicy was never intended to be a security control.
In order to change the PowerShell Execution Policy you have to start PowerShell as an administrator and run the following command Set-ExecutionPolicy ExecutionPolicy RemoteSigned. You can also set the RemoteSigned to unrestricted, but it is discouraged by Microsoft.
Alright, but what if you are not an administrator yet? You have basic low privilege access to a Windows machine, and you need to upgrade your shell to something more stable, or to add some Empire persistence. How can you change the ExecutionPolicy?

🦑🖧 How to install and connect OpenVPN client on Debian-kali 2020-parrot ?

1) Installing the OpenVPN Client
OpenVPN packages are available in the default Debian repositories.

2) Open a terminal on your Debian system and update the apt cache.

3) After that, install the OpenVPN package.

4) Open a terminal and run the commands to install the openvpn client on Debian:

sudo apt update

sudo apt install openvpn -y

5) Connect to OpenVPN Server
Copy the openvpn client config file to your Debian machine.

6) You can use the –config command line parameter to provide a configuration file.

7) The command will read all the necessary data to create a vpn from this file.

8) Let's run the following command to connect to the openvpn server:

openvpn --config client.ovpn
You should see the following output:

10) Check the connection
After a successful connection, a new IP address will be assigned on the tun0 interface by the OpenVPN server.

11) You can check it with the following command:

ip a show tun0

🦑Output:

4: tun0: mtu 1500 qdisc fq_codel state UNKNOWN group default qlen 100

You can also check the OpenVPN server log to check the connection status:

12) the log file

tail -f /var/log/openvpn.log

🦑🍌 Windows 10 update removes the need to remember passwords with Windows Hello and FIDO2:

1) Last fall, we learned that Windows aims to eliminate the need to remember passwords using Windows Hello, a biometrics-based technology.

2) This makes it a little easier that there is no need to keep somewhere a separate list of all the different passwords and password versions that you use.

3) Now achieving this goal is made even more realistic as Windows Hello has achieved FIDO2 certification, which allows biometrics and PINs to be treated as secure authenticators.

Say goodbye to passwords

4) Microsoft knows what everyone thinks about passwords, noting that "no one likes passwords (except hackers)."

5) Since the advent of the computer systems that we all use, we have had to remember passwords - for computer systems, websites, applications, devices, and the like.

“People don't like passwords because we have to remember them,” Microsoft explained.

"As a result, we often create passwords that are easy to guess — making them the first target for hackers trying to gain access to your computer or network."

6) The need for confidentiality meant passwords for everything.

This increased need has led to different types of passwords.

7) Instead of your birthday, anniversary, dog name, street name, etc., you were forced to remember more complex passwords or have a password manager.

8) These are the reasons that led the company to create Windows Hello last fall.

9) This biometrics-based technology used FIDO, which allowed Windows users to authenticate secure access using only fingerprints or facial recognition.

Windows Hello has now received FIDO2 certification, which adds acceptable standards for authentication.

10) This updated method now also includes the use of PINs.

11) The FIDO Alliance explained in a press release that “FIDO2 is a set of standards that enables easy and secure access to websites and applications using biometrics, mobile devices and / or FIDO security keys.

12) FIDO2's simplified login process is provided with robust cryptographic protection that far surpasses passwords, protecting users from phishing, all forms of password theft and replay attacks. ”

Windows 10x was recently announced.

13) Here you can see if these tools and the general list of Windows 10x options will be available

Windows Hello and FIDO2 integration
You can take advantage of Windows Hello with FIDO2 by updating Windows 10 to version 1903.

14) Microsoft Edge, Google Chrome and Mozilla Firefox will support biometrics and PINs.

Other Microsoft products such as Office 365, Skype, and Xbox Live can also authenticate using Windows Hello.

15) Will you be upgrading to Windows 10 to take advantage of Windows Hello and FIDO2 technologies?

🦑What is a DNS leak and why it matters👨⚕️ ?

1) When using an anonymity or privacy service, it is extremely important that all traffic originating from your computer is routed through the anonymity network.

2) If any traffic flows outside of a secure connection to the network, any adversary controlling your traffic will be able to register your activity.

3) DNS or Domain Name System is used to translate domain names such as www.privacyinternational.org into numeric IP addresses, for example. 123.123.123.123, which are required to route data packets on the Internet.

4) Whenever your computer needs to contact a server on the Internet, for example when you enter a URL in your browser, your computer contacts the DNS server and asks for an IP address.

5) Most ISPs assign their customers a DNS server that they control and use to log and record your online activities.

6) Under certain conditions, even when connected to the anonymity network, the operating system will continue to use its default DNS servers instead of the anonymous DNS servers assigned to your computer over the anonymity network.

7) DNS leaks pose a serious privacy threat because an anonymous network can provide a false sense of security while personal data is leaked.

8) If you are concerned about a DNS leak, you must also understand DNS transparent proxy technology to ensure that the solution you choose preserves your privacy.

🦑Variations and Symptoms of the WordPress Redirect Hack :

1) Classic Redirection Hack

The hacked redirect has been around since the longest time. Every time someone visits your website, they're redirected to questionable links like pharma sites, adult websites etc.

2) Redirection via Search Results

When website is opened by entering the URL in the browser, it opens fine. But when opened by searching on Google, it redirects to malicious websites.

3) Device Specific WordPress Redirection

The website only redirects when opened from mobile device or only redirects when opened from desktop depending on what type of malware is present.


4) Push Notifications Hack

We've seen this one since last few months where hackers also show browser push notifications to your visitors. Usually these push notifications point to porn websites.


5) Geography Specific Redirection

In some cases, some visitors of yours might see a redirection and some might not. This could be because hackers program the malware to work only for certain geographies. Where exactly the malware redirects also can be tailored geography-wise by hackers.
