The OWASP Foundation Has Selected The Technical Writer For Google Season Of Docs

The OWASP Foundation has selected the technical writer for Google Season of Docs by Fabio Cerullo

The OWASP Foundation has been accepted as the organization for the Google Seasons of Docs, a project whose goals are to give technical writers an opportunity to gain experience in contributing to open source projects and to give open-source projects an opportunity to engage the technical writing community.

During the program, technical writers spend a few months working closely with an open-source community. They bring their technical writing expertise to the project's documentation, and at the same time learn about open source and new technologies.

The open-source projects work with the technical writers to improve the project's documentation and processes. Together they may choose to build a new documentation set, or redesign the existing docs, or improve and document the open-source community's contribution procedures and onboarding experience. Together, we raise public awareness of open source docs, of technical writing, and of how we can work together to the benefit of the global open source community.

After a careful review and selection process, the OWASP Foundation has picked the primary technical writer who will work along the OWASP ZAP Team for the next 3 months to create the API documentation of this flagship project.

Congratulations to Nirojan Selvanathan!

Your account is hacked. Your data is stolen. Learn how to regain access.

Hi,

I am a hacker, and I have successfully gained access to your operating system.
I also have full access to your account.

I've been watching you for a few months now.

The fact is that your computer has been infected with malware through an adult site that you visited.
If you are not familiar with this, I will explain.
Trojan Virus gives me full access and control over a computer or other device.
This means that I can see everything on your screen, turn on the camera and microphone, but you do not know about it.
I also have access to all your contacts and all your correspondence.

Why did your antivirus not detect malware?
Answer: The malware I used is driver-based, I update its signatures every 4 hours. Hence your antivirus is unable to detect its presence.
I made a video showing how you satisfy yourself in the left half of the screen, and the right half shows the video you were watching at the time.

With one mouse click, I can send this video to all your emails and contacts on your social networks.
I can also make public all your e-mail correspondence and chat history on the messengers that you use.

If you don't want this to happen, transfer $950 in Bitcoin equivalent to my Bitcoin address (if you do not know how to do this, just search "buy bitcoin" on Google).

My Bitcoin address (BTC Wallet) is: 15NCWERN56DQNf4WiPLR2txgiEF2np5Q2g

After confirming your payment, I will delete the video immediately, and that's it. You will never hear from me again.
I will give you 50 hours (more than 2 days) to pay. I will get a notice, when you open this email, and the timer will start.
Filing a complaint somewhere does not make sense because this email cannot be tracked like my Bitcoin address.

I never make any mistakes.
If I find that you have shared this message with someone else, the video will be immediately distributed.

Best regards!

Evil Limiter: Taking Control Of Your Network Bandwidth

Ever wanted to block someone from the network or limit their bandwidth without having the network admin privileges? Well Evil Limiter has got you covered then.

An amazing tool to help you control your network without having access to the admin panel.
Today I'm gonna show you how to use this interesting tool to take control of your network.

Requirements:

1. A PC or Laptop with Linux OS.
2. A Network Adapter.
3. Access to the Network you want to control.
4. sudo or root access on your Linux OS.

First of all we will download the tool from its github repository:
https://github.com/bitbrute/evillimiter

You can download and extract the zip file from the link above or you can clone evillimiter repository using git like this:

git clone https://github.com/bitbrute/evillimiter

Now lets install the downloaded tool on our machine
Step 1: Move inside the downloaded github repository

cd evillimiter

Step 2: To install type

sudo python3 setup.py install

wait for the installation to finish (May take some time)

Step 3: To run type

sudo evilimiter

Voila! That's it, you got it up and running on your machine

Now how do you control your network with it, its very easy.
It should detect your network automatically but yeah you can set it up manually as well using the command line argument -i.

After you have selected the right interface to control, you need to scan your network for live hosts. To perform the scan type

scan

you can pass an optional flag to the scan command which is range which will help you to specify the range of ip addresses you want to scan like this

scan --range 192.168.1.1-192.168.1.100

The above command will scan a total of 100 hosts from 192.168.1.1 to 192.168.1.100

Now after you have scanned your network next thing is to list the hosts that have been discovered during the scan for that you type the hosts command like this

hosts

Now you know the hosts on your network and now you should know which host you wanna block or limit based on the mac address of the host. Remember the host id of the host that you want to block or limit bandwidth of and lets do the magic.
to block a host from using the internet we simply specify the block command followed by the host id of the host that we want to block like this

block 1

if instead of blocking the host we just want to limit his internet bandwidth we can do just that by using the limit command followed by the host id and then the bandwidth that we want to allocate to that particular host like this

limit 1 100kbits

Wohooo! yeah its that easy and yes you can do all this without having the network admin role.
Now if you want to show mercy on that poor guy (blocked host), you can set him free by using the free command followed by the host id like this:

free 1

Well isn't administrating your network bandwidth so easy now.
Hope you enjoyed this tutorial.:)

TERMINOLOGIES OF ETHICAL HACKING

What is the terminologies in ethical hacking?

Here are a few key terms that you will hear in discussion about hackers and what they do:

1-Backdoor-A secret pathway a hacker uses to gain entry to a computer system.

2-Adware-It is the softw-are designed to force pre-chosen ads to display on your system.

3-Attack-That action performs by a attacker on a system to gain unauthorized access.

4-Buffer Overflow-It is the process of attack where the hacker delivers malicious commands to a system by overrunning an application buffer.

5-Denial-of-Service attack (DOS)-A attack designed to cripple the victim's system by preventing it from handling its normal traffic,usally by flooding it with false traffic.

6-Email Warm-A virus-laden script or mini-program sent to an unsuspecting victim through a normal-looking email message.

7-Bruteforce Attack-It is an automated and simplest kind of method to gain access to a system or website. It tries different combination of usernames and passwords,again & again until it gets in from bruteforce dictionary.

8-Root Access-The highest level of access to a computer system,which can give them complete control over the system.

9-Root Kit-A set of tools used by an intruder to expand and disguise his control of the system.It is the stealthy type of software used for gain access to a computer system.

Hacker Group 'Moses Staff' Using New StrifeWater RAT In Ransomware Attacks

A politically motivated hacker group tied to a series of espionage and sabotage attacks on Israeli entities in 2021 incorporated a previously undocumented remote access trojan (RAT) that masquerades as the Windows Calculator app as part of a conscious effort to stay under the radar.

Cybersecurity company Cybereason, which has been tracking the operations of the Iranian actor known as Moses Staff, dubbed the malware "StrifeWater."

"The StrifeWater RAT appears to be used in the initial stage of the attack and this stealthy RAT has the ability to remove itself from the system to cover the Iranian group's tracks," Tom Fakterman, Cybereason security analyst, said in a report. "The RAT possesses other capabilities, such as command execution and screen capturing, as well as the ability to download additional extensions."

Moses Staff came to light towards the end of last year when Check Point Research unmasked a series of attacks aimed at Israeli organizations since September 2021 with the objective of disrupting the targets' business operations by encrypting their networks, with no option to regain access or negotiate a ransom.

The intrusions were notable for the fact that they relied on the open-source library DiskCryptor to perform volume encryption, in addition to infecting the systems with a bootloader that prevents them from starting without the correct encryption key.

To date, victims have been reported beyond Israel, including Italy, India, Germany, Chile, Turkey, the U.A.E., and the U.S.

The new piece of the attack puzzle discovered by Cybereason comes in the form of a RAT that's deployed under the name "calc.exe" (the Windows Calculator binary) and is used during the early stages of the infection chain, only to be removed prior to the deployment of the file-encrypting malware.

The removal and the subsequent replacement of the malicious calculator executable with the legitimate binary, the researchers suspect, is an attempt on the part of the threat actor to cover up tracks and erase evidence of the trojan, not to mention enable them to evade detection until the final phase of the attack when the ransomware payload is executed.

StrifeWater, for its part, is no different from its counterparts and comes with numerous features, chief among them being the ability to list system files, execute system commands, take screen captures, create persistence, and download updates and auxiliary modules.

"The end goal for Moses Staff appears to be more politically motivated rather than financial," Fakterman concluded. "Moses Staff employs ransomware post-exfiltration not for financial gain, but to disrupt operations, obfuscate espionage activity, and to inflict damage to systems to advance Iran's geopolitical goals."
