DFIR | [Fix] Cuckoo Error : Error starting virtual machine | VBoxManager error

If you are reading this, you might probably encountered the following error while performing the sample analysis in Cuckoo,  Error starting Virtual Machine / VBoxManage error.  This error happens when there is some communication issue between the guest and host or with the VM snapshot. The network configuration of the guest VM should be set as "Host only network" and verify the connectivity between the host and Guest by pinging each other. If that is fine, then check the guest VM snapshot. In my case, i had multiple snapshot and the one Cuckoo was invoking creates the issue. What i did was, i deleted all the existing snapshots and created a clean snapshot, also did a graceful shutdown of the Guest VM (Windows 7 in my case). Also noticed that, while running cuckoo, it try to load the VM snapshot named base2 . Instead of editing any configurations,  i just named the snapshot "base2". Then i put a sample on Cuckoo for analysis. The process completed without any issues.

[FIX] Fingerprint reader not working properly??

The fingerprint reader on my laptop was not working properly since last couple of month. Suspecting after some update from Microsoft. It was not completely working, sometimes it work perfectly and often sometimes not. Especially after my laptop goes sleep.

So i uninstalled and reinstalled the driver with the latest update, did some googling and couldn't get a solution. However, i though of checking the power management settings. And unchecked the "Allow the computer to turn off this device to save power" under the device's power management (From Device Manager). The issue is fixed and the fingerprint reader is working fine.

Thought of sharing this as some of my friends had the same issue. Also i can see a lot of queries in the internet regarding this fingerprint reader malfunction. Always keep your OS and the drivers up to date and don't download any third party tools to fix issues with your machine.

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 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

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

Cisco Modular Policy Framework (MPF) : A brief Introduction

Modular Policy Framework (MPF) configuration defines set of rules for applying firewall features, such as traffic inspection, QoS etc. to the traffic transiting the firewall There are 3 main components in creating a MPF. 1) Class Map Class map is used to identify the type of traffic. This can be done by creating an ACL. 2) Policy Map Policy Map specifies what action the ASA should take against the traffic identified by the Class Map. 3) Service Policy Finally Service policy specifies where to apply it.

Microsoft Windows NLB Feature for Stateful Applications

NLB is a software-based load balancer (Windows Feature) that resides on each member in the cluster. Load Balancing is based on number of client connection requests and the NLB algorithm does not dynamically respond to changes in the load on each cluster host (such as the CPU load or memory usage or Network Usage). Thus, If client population is less and/or the connections produce varying loads on the server, the load balancing algorithm of Microsoft NLB is less effective. Udacity has special offers worldwide to help anyone learn important, higher-paying job skills during this challenging time. Click here to get your offer and start learning now! To understand how NLB preserve the session state, first let me take you through the difference between a stateful and stateless connections: Stateless The application connection is said to be stateless if the server does not store any state about the client session instead the session data is saved at th client side. The server does n

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
