kandi X-RAY | ransomware Summary

ransomware is a Go library typically used in Security, Encryption applications. ransomware has no bugs, it has no vulnerabilities and it has medium support. You can download it from GitHub.

This project was developed for the Computer Security course at my academic degree. Basically, it will encrypt your files in background using AES-256-CTR, a strong encryption algorithm, using RSA-4096 to secure the exchange with the server, optionally using the Tor SOCKS5 Proxy. The base functionality is what you see in the famous ransomware Cryptolocker. The project is composed by three parts, the server, the malware and the unlocker. The server store the victim's identification key along with the encryption key used by the malware. The malware encrypt with a RSA-4096 (RSA-OAEP-4096 + SHA256) public key any payload before send then to the server. This approach with the optional Tor Proxy and a .onion domain allow you to hide almost completely your server.

MONGO_INITDB_ROOT_USERNAME and MONGO_INITDB_ROOT_PASSWORD are used to setup superuser account to manage overall databases.
You can connect as admin permission using this connection string mongodb://:@mongo:27017 and create a database myDatabase, after that you also have to create user with a role to allow query database.

This answer is no longer directly relevant, as we know the platform is Windows 10, but for future reference: When you get to Windows 11 you can have a similar problem if "Controlled Folder Access" is enabled: this can prevent applications from accessing user folders. You will need to add Dyalog APL to the list of "allowed apps", which is quite straightforward if you have admin rights on your machine.

If you start APL and get a warning about being unable to rebuild the command cache because a folder does not exist, go to the "Ransomware protection" section of Windows Security settings, select "Allow an app through controlled folder access", select "Add an app", and you should be able to select APL from a list of "recently blocked apps".

If you have not recently been blocked you will need to select dyalog.exe using a file explorer.

Why is the output not showing here?

Asked 2021-Oct-06 at 13:48

So I have an odd powershell issue that I'm not sure about here, perhaps someone with more experience than me can advise?

Basically I'm searching servers for any Services & Scheduled Tasks that are not Microsoft, then checking config files for a certain name.... The code used is slightly older because some of the servers are 2008 & powershell hasn't been updated on them (long story involving ransomware)..

If I separate the code, I get the expected results, but if I combine the code, some of the output is missing....

ANSWER

Answered 2021-Oct-06 at 13:48

I happened to have an old 2008 VM and was able to test this. Try adding -and $_.HostName -notlike "HostName" like this to the line below. I got no hits because of the -notlike filters you have but that's likely because MS didn't have as many tasks running under the user context back then, especially on servers. Adding that last -notlike strips out the headers for the nested tasks in other folders.

How to delete the exclusions from Microsoft defender Win10?

Asked 2021-Mar-18 at 10:50

I have problem deleting the following folders from the exclusions because my CPU is on 90% Usage because of these exclusions and I don't know when and why even they are on my list. I have updated windows yesterday and my CPU starts heating up... I scanned the PC and no threat detected. But suddenly I opened the exclusion list and found some garbage is in the list which is not able to delete while the Remove button is disabled. Is this a ransomware update attack or a malware attack on Microsoft server side which is providing vulnerable updates?

...

ANSWER

Answered 2021-Mar-18 at 10:50

You can do 3 things to delete this.

1: Check Log files of updates and read it what happened during update.

2: Check in Registry if the above list is available in HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Defender\Exclusions and manually delete them.

3: If the above options didn't solve your Problem, I am sure your PC is hijacked. To solve it read carefully the next part.

Reset Internet Explorer and delete all addons, Delete any new internet browser/Software you have installed after updating Windows and Search for this directory in the registry: HKLM\SOFTWARE\WOW6432NODE\Microsoft\Security Center\UACDisableNotify - "1""1" -Hijack.Security.UACDisableNotify If you find this, Just Disconnect Internet, Boot safe Mode and delete all the threats in HKLM\SOFTWARE\WOW6432NODE\Microsoft\Security Center\ You will find many of them.

ANSWER

Answered 2021-Feb-05 at 08:37

the problem is that you encrypt then decrypt. Your encryption and decryption function is working fine the issue is that you always seek to the beginning of the file to write any changes this will work fine with encryption and will work fine with decryption if the the plaintext and ciphertext is of same size(no padding) but will place decrypted plaintext that is not as same same size of ciphertext at beginning of file and leave the rest of file unchanged so you need to truncate the remainder part of ciphertext.

QUESTION

Preventing deletion of noncurrent objects

Asked 2020-Dec-16 at 05:55

I'm storing backups in Cloud Storage. A desirable property of such a backup is to ensure the device being backed up cannot erase the backups, to protect against ransomware or similar threats. At the same time, it is desirable to allow the backup client to delete so old files can be pruned. (Because the backups are encrypted, it isn't possible to use lifecycle management to do this.)

The solution that immediately comes to mind is to enable object versioning and use lifecycle rules to retain object versions (deleted files) for a certain amount of time. However, I cannot see a way to allow the backup client to delete the current version, but not historical versions. I thought it might be possible to do this with an IAM condition, but the conditional logic doesn't seem flexible enough to parse out the object version. Is there another way I've missed?

The only other solution that comes to mind is to create a second bucket, inaccessible to the backup client, and use a Cloud Function to replicate the first bucket. The downside of that approach is the duplicate storage cost.

...

To answer this:

However, I cannot see a way to allow the backup client to delete the current version, but not historical versions

When you delete a live object, object versioning will retain a noncurrent version of it. When deleting the noncurrent object version, you will have to specify the object name along with its generation number.

Just to add, you may want to consider using a transfer job to replicate your data on a separate bucket.

Either way, both approach (object versioning or replicating buckets) will incur additional storage costs.

QUESTION

HOWTO: Fix an out-of-sync TFS workspace after a restore

Asked 2020-Aug-13 at 06:35

Due to a ransomware virus, we had to restore a back-up image of the TFS server code repository that we made some days ago.

Fortunately I have an updated copy in my local workspace with the latest changes that were checked in just before the disaster. The snapshot restored does not have this latest changes. So now some files in my local workspace are newer than those in the snapshot restored, I mean my local workspace has some files which contain changes not present in the snapshot restored. Furthermore and despite of some files in my local workspace are different from those in the snapshot, they are not marked as checked-out in Team Explorer.

As the latest changes are in my local workspace (and not in the snapshot because they were lost in the restore process) I would like to check-in my local workspace into the current restored snapshot so that my local workspace gets exactly the same as the snapshot (TFS server code repository). How can I do it?

I have thought to perform a "Get Latest version" on my local workspace in order to sync it with the snapshot (code repository). I understand that "Get Latest Version" will find the differences (and conflicts to resolve) between my local workspace and snapshot and then it will automatically check-out the necessary files so that I can review and check-in them later. Is that the correct way to proceed in this situation? Am I right? Also, as far as I know, doing a "Get Latest Version" don't delete the changes locally in my workspace, right?

Take a look at Reconciling workspaces. There is also a command-line equivalent if there are a lot of changes and you seem to want to take your workspace as-is: tf resolve.
