Facebook Bullying : What to do?

In the light of recent cyber bullying incidents, i thought of writing an article that might help some of you on how to respond and what to do when you face such incidents.

First of all, let's understand what is a cyber bullying? It is the act of harassing someone using the electronic medium especially Internet. Many of us may already experienced this in one way or another. Some argue it as freedom of expression but at most of the times, it crosses all the boundaries of tolerance and patience. Bullying can happen due to ideological differences, opinions, political or even religious reasons. Now, i will get in to details of these reasons.

Most of the bullying may seems as an individual opinion or comment. But there are many groups and organizations who get paid for bullying someone. Yes, it may seems odd but it is a reality. The political parties, religious groups or organizations, ideological movements, fan groups etc have their own IT groups who are assigned to work on social media and sharing, publishing their own propaganda, opinions and last but not the least, they do cyber bullying.

For example, assume there is a political party PARTY X, and they have a a number of volunteers working at their IT cell. Their major job is to share PARTY X's political ideologies , achievements, failures as posts or even as fake news. When thousands of volunteers share something, to the more people it reach, the more impact it has in the common viewer's mind. Let's assume a person named Bob wrote a post about a fake news made by this PARTY X, then the party's IT volunteers role will be changed to Cyber Bullies. They , in groups starts writing bad and vulgar comments about Bob on his Facebook wall or even on his friends wall, eventually Bob feels frustrated and may delete the post or his profile. When these IT cell/group report abuse Bob's profile, even Facebook might think that there is something inappropriate on Bob's profile. And Facebook may send a notice to Bob instead of identifying the real culprit. Well it hard for Facebook also to identify what is right and wrong over internet, and hence they heavily depends on their users. When their users report abuse, then they may check it. Otherwise, nothing happens. Similar behaviors happens from other celebrity fan groups, religious groups, propaganda groups etc. They all works like an online mafia.

Recently , there are some cases reported on Cyber bullying against women and children. It also happened in the same way as political parties do. Some people, in groups posts many vulgar comments and harassing them on social media. Most of the victims eventually lose their peace and mental health in long term.

So if you are facing Cyber bullying, what to do? How to respond?
Well Facebook has provided their own guidelines on cyber bullying. I am sharing those links at the end of this article. This is what Facebook policy says, whenever you face or notice a cyber bullying,
  • Document and report it. Help your friend report the post to Facebook. You may also want to take screenshots of any abusive posts, comments or messages in case there's an ongoing issue or you need to show them to someone later. Your friend may also want to unfriend or block this person.
  • Offer support. Ask your friend what you can do to support them, but don’t speak for your friend unless they ask you to.
  • Stay calm. Try to help your friend avoid escalating the problem or acting aggressively. If you and your friend agree that the incident wasn’t a big deal, suggest they let it go. Bullies are often just looking for a reaction, so not giving them one may discourage this kind of behavior in the future.
  • Remind your friend they're not alone. Let your friend know that you want to help them handle this. Remind your friend that they haven’t done anything to deserve this and that bullying can happen to anyone.
  • Don’t keep it a secret. If your friend needs additional support, encourage them to reach out to someone they trust to talk about the situation. If you’re worried about your friend’s safety, tell someone immediately.
But to what extend this will help you? well the answer is, it depends on various factors. If you are living in a Country that has a good law on Cyber security and IT crime, then legally documenting and reporting may help you to stop the act to some extend. But the mental torture and stress caused by this , for that there may not have a solution.

Sadly , most of the Countries doesn't have a strong Cyber crime laws in place. So even if the police identify the cyber bullies and caught them, there is no way to give a appropriate punishment to them. First of all, weighing the effect of a cyber crime might be very hard. Though act of writing some comments or posting some photos may not seems as harmful as stealing some thing or killing someone. But since the entire world is connected over internet, writing such comments or photos may end in much wider consequences and there are cases where people even did suicide because of such bullies. This weakness in law act as a catalyst agent to those bullies because they are almost confident that nothing bad can happens to them legally.

Even though, most of the social community websites like Facebook has their own guidelines on do and don't, but those things never acts as a deterrent to the cyber bullies. They will continue to write in a vulgar and abusive way. Even Facebook cant find a way to control this. Also note that retaliating and responding to bullies never going to help you as they comes with an agenda and they are so many in numbers as well.

So control your activities in the Internet. Be sure about what you are writing and what you are sharing. Always keep in mind that, what you are going to do on sites like Facebook is going to the public. Be sure yourself. And as of now, there is no way to prevent the cyber bullying completely. But as individuals, you can keep your personal space on the internet safe and clear. Recheck your privacy settings and have a control on your profile and its content. And be vigilant and if you want to move legally against cyber bullies, all you can do is follow the Facebook guidelines and cyber crime laws in your country.

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 ...

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

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...

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...
