Why you should not believe in Online Reviews and Social networking sites?

Most of us, before buying a product from Amazon/Flipkart, or before booking a movie ticket, we might go through the review section to see what others think about it, how good it is?, what are the pros and cons? etc.

Let me tell you a fact. Though there are genuine reviews written by genuine customers/users, majority of the reviews are paid reviews. Similarly paid opinions can be seen in forums like Quora, Yahoo Answers.When it comes to social networking websites, there are big companies working for corporate, political parties, ideological institutions.

Many of us are addicted to these social networking sites and we like and share things which we are not sure about. All want to monetize their profit and for that they will do even the worst methods to make things viral.These institutions pay millions of money to distribute and publicize their propaganda. In short, to brainwash the audience.

When thousands write a good review of a bad product, that product automatically becomes good in the public.

Most of the companies are running affiliate programs. Which means, you promote us and if someone buys a product through you, we will give a commission to you. One of the Site defines it's affiliate program as,

"You can use various promotional methods to earn easy commissions including placing banners, links, and writing product reviews on your website or blog. You will receive customized links for all the promotions, through which we will track sales. When any customer, referred by you, makes a purchase, you get paid."

There are plenty of online job sites serves over the internet. If you signup, you can see many online job offerings such as harvesting likes,up-votes, review writings, data entry etc.

It's funny that, you don't even need to find words to write a review. The review content is also provided by the marketing company and all you need to do is copy and paste it on relevant blogs, forums websites under your account (even from multiple accounts).

I have taken few screenshots from one of those site. Lets go through that and understand how companies can brainwash you with reviews and posts. When thousands write a good review of a bad product, that product automatically becomes good in the public.

The following screenshots are job advertisements , the employer is paying money to publicize their hashtag and their product.

Another job, the worker need to signup, comment and give a link to the product website.

See the instructions. Just follow this and get paid. Spread the propaganda, or publicize a product no matter how good or bad it is.

This job is to do the up-votes..lol.

Due to the large influence of Social Networking sites on common people, any one can throw money to circulate and publicize their propaganda. Even the Visual medias are also working like that.

So with this article, i remind each and everyone that Use your Brain, Think and Act. Don't blindly believe everything on the Internet. Don't blindly believe in what others says.

Everything around us are trying to brainwash our thoughts. So again, Use your Brain ! Always!

Now set the DH group to 24, which is the strongest offered as of now in the ASA. #ssl dh-group group24 An

PrintNightmare (CVE-2021-1675) PoC exploit Walkthrough

I am not an exploit developer but was interested to see how this vulnerability can be exploited. So i tried to replicate the infamous PrintNightmare vulnerability using the following PoCs ( https://github.com/cube0x0/CVE-2021-1675 ) and ( https://github.com/rapid7/metasploit-framework/pull/15385 ) However i had trouble with the new metasploit module (auxiliary/admin/dcerpc/cve_2021_1675_printnightmare) and i couldn't able to exploit the machine successfully. So i tried the second PoC from cube0x0. This one has done the magic. I just followed the guidelines with couple of tweaks. First of all, i installed the impacket (cube0x0 version) which will install the required modules and files. After that i set up a samba share with an anonymous login. This is required for hosting the dll file. I edited the smb.conf with the following settings. [global] map to guest = Bad User server role = standalone server usershare allow guests = yes idmap config * : backend = tdb s

Difference between Azure management groups, Subscriptions and Resource groups

image courtesy : https://docs.microsoft.com Azure management groups help you manage your Azure subscriptions by grouping them together. If your organization has many subscriptions, you might need a way to efficiently manage access, policies, and compliance for those subscriptions. Azure management groups provide a level of scope above subscriptions. Azure subscriptions help you organize access to Azure resources and determine how resource usage is reported, billed, and paid for. Each subscription can have a different billing and payment setup, so you can have different subscriptions and plans by office, department, project, and so on. Resource groups are containers that hold related resources for an Azure solution. A resource group includes those resources that you want to manage as a group. You decide which resources belong in a resource group based on what makes the most sense for your organization. reference : https://docs.microsoft.com

What is a Gratuitous ARP? How is it used in Network attacks?

Many of us encountered the word "Gratuitous" while exploring the network topic on ARP, The Address Resolution Protocol. Before explaining Gratuitous ARP, here is a quick review on how ARP works. ARP provides IP communication within a Layer 2 broadcast domain by mapping an IP address to a MAC address.For example, Host B wants to send information to Host A but does not have the MAC address of Host A in its ARP cache. Host B shoots a broadcast message for all hosts within the broadcast domain to obtain the MAC address associated with the IP address of Host A. All hosts within the same broadcast domain receive the ARP request, and Host A responds with its MAC address. We can see the ARP entries on our computers by entering the command arp -a . So, back to the topic on what is a Gratuitous reply, here is a better explanation. Gratuitous arp is when a device will send an ARP packet that is not a response to a request. Ideally a gratuitous ARP request is an ARP request packe

Recovery Procedure: Alcatel-Lucent Omni-Switch not booting AOS: Going to Mini-boot prompt.

Problem: Switch not booting AOS; Going to Mini-boot prompt. Model: Alcatel-Lucent OS6850 [Note:The same procedure might be applicable for different models of Omni-Switches, However, for this illustration, i have used OS-6850 ] Reason: This problem may occurs due to corrupt AOS image files or misconfigured boot parameters. Hence switch cannot boot the images properly and will go to Mini-boot prompt. Work Around: [Note: This zmodem procedure consumes a lot to time to finish the process.] 1.) Power off your OS6850 2.) When you switched it back on, stop it before the Miniboot (there is some counter counting down from 4). Press Enter to break. 3.) You will have the following prompt " => " 4.) Enter " setenv baudrate 115200 ”. Increasing baudrate helps to increase the data transfer speed using zmodem. 5.) Enter " saveenv " 6.) Enter " boot " 7.) The switch should run now in baud rate 115200 (so you have to change your clients ter
