Is the Employee Data as Important as Customer data?

Hi guys, There is this Organization, that boasts about standards and policies. Yes, though these things are inevitable for the reputation of the company and data security, it actually matters only if it really implemented in practice.
I have seen many organizations, that creates policies only for the Audit/Compliance sake. 

Do you have a policy on data security? YES
Do you have a data security policy implemented in practice? hmmmm!!!.

Companies might be certified and meeting the regulatory standards but nothing has actually in practice. 
Let me share with you an incident.I accidentally discovered this thing in a normal google search. I searched something and i found an interesting result. Out of curiosity, i clicked on that particular Google search result and it took me to that Company's Employee directory. The Whole directory. I can search any Employee , i can see their Employee code, department and location. If you want to know how big the list is? Yes, a few thousands.

I first encounter this result more than a year back. I knew some of the Guys from that organization and i informed them. Some of them understood its importance and as per them, they escalated it. And hoped that they resolved it.

Last week, i saw that same result again in the Google search. Same database. 
They are supposed to show this information only once an employee is properly authenticated. Somehow, they are not bothered to show it directly without any authentication required. I searched about this organization and they holds certifications like ISO 27001 ,ISO 9001. Also they handles projects for various Governments and private firms. Such a big company should have some level of responsibility on keeping employee's information securely. These information can be used for social engineering and other privacy misuse. In many Countries, these info is considered as Personally Identifiable Information (PII) and breach of this can lead to million dollar fine. And its reputation will be a Question. 

So ever after 1 year of informing, they are not bothered of securing the employee info. This can be called as a Big Negligence. Despite of being an ISO 27001 certified organization, and have data security policies, they are not bothered of this data leak. So many questions will arise. 
  • What audit has actually happened and how they are certified? 
  • Do they periodically audit their information/data infra? 
  • Who is responsible if this data is misused?
  • Is their enough data security mechanisms for other information such as Customer info,Project details?

I discussed this with one person and he raised this concern with me.
Recent breaches reveals that the personal/official , financial data is not as secure as we are told... But your point put forward an open ended question: “can a company secure their client’s data when they can’t secure their employee data?” ...

So what actually matters is, Are you really practicing a Security policy? Is everyone aware of it?
Does your employee/management have that due care and due diligence?
Have the certifications, but not for an accreditation sake. Have everything in practice rather that boasting. 

Note: The data is available on web and can be searched using the google search. No manipulation or no tools needed. They reveal their employee info just like that. A technically sound person can manipulate the URL and may spill more info. This was also informed to them, sadly it seems nobody is bothered. Company Name is not mentioned due to privacy.

Cisco ASA: Disable SSLv3 and configure TLSv1.2.

For configuring TLS v1.2, the ASA should run software version 9.3(2) or later. In earlier versions of ASA, TLS 1.2 is not supported.If you are running the old version, it's time to upgrade. But before that i will show you the config prior to the change. I am running ASA version 9.6.1 Now ,set the server-version to tlsv1.2, though ASA supports version tlsv1.1, its always better to configure the connection to more secure. Server here in the sense, the ASA will be act as the server and the client will connect to the ASA.     #ssl server-version tlsv1.2 set the client-version to tlsv1.2, if required.     #ssl client-version tlsv1.2 ssl cipher command in ASA offers 5 predefined security levels and an additional custom level.     #ssl cipher tlsv1.2 high we can see the setting of each cipher levels using #show ssl cipher command. Now set the DH group to 24, which is the strongest offered as of now in the AS...

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...
