Smokeloader
Smokeloader
Smokeloader is a very intricately designed malicious software with a multitude of a facade, hence it’s one complicated cyber threat. It comes in various disguises like bots, trojans etc. to deliver malware. That malware can further be used for launching a cyberattack on a larger scale. When bots are used to release malware on a large scale, they are generally done with the purpose of zombifying IOTs.
This class of malicious bots was first spotted around the year 2011.
Smokeloader is notorious for the speciality of self-protection, and it comes with numerous other plugins. It has several capabilities, and depending on the modules included, can deliver malware in various ways.
Some examples of smokeloader attacks are -
Smoke Loader uses HTTP for C2
Smoke Loader searches for credentials stored in web browsers.
Smoke Loader searches through Outlook files and directories.
Smoke Loader recursively searches through directories for files
Smoke Loader adds a Registry Run key for persistence and adds a script in the Startup folder to deploy the payload
Smoke Loader adds a Visual Basic script in the Startup folder to deploy the payload.
Smoke Loader deobfuscates (simplifies into readable material, i.e., high-level language) the code.
ZLoader
ZLoader
ZLoader (also known as DELoader and Terdot) can be a pernicious program disseminated through malevolent web pages that show fake error notices. Research has shown that ZLoader meddles with frameworks with some other pesky or damaging software.
A banking Trojan called Zeus that can record your keystrokes is used. Don’t open records downloaded from web pages that show this error message, or something similar.
When the malicious website is visited, it displays an error message.

It then encourages visitors to fix this error by taking the action (usually clicking a link that prompts users to download something).
ZLoader disperses Zeus, the Trojan competent for recording keystrokes and taking credentials such as logins, and passwords. Cybercriminals abuse this data to make fraudulent transactions, purchases, and so on.

Black cat
Black cat

What sets dark cat apart is that the ransomware is totally command-line driven, human-operated, and profoundly configurable. It comes with the capacity to utilize distinctive encryption schedules, spread between computers, and permanently blackout virtual machines and ESXi VMs. It is capable of naturally wiping ESXi records to avoid recuperation.
The ransomware can be configured to utilize four distinctive encryption modes. ALPHV Black Cat can be designed with domain credentials as well. It can be utilized to spread the ransomware and encrypt other IOTs on the network. The executable will at that point extricate PSExec to the %Temp% folder and utilize it to copy the ransomware to other devices on the network. After that, execute it to encrypt Windows machine located remotely. When propelling the ransomware, the partner can utilize a console-based client interface that permits them to screen the movement of the attack.
To keep users safe from such attacks, cybersecurity agencies work round the clock to collect information and analyse the received data on any new cyber threat uproar.
To avoid any cyber threat on a personal level, don’t click any suspicious links or visit sites that mimic the usual sites. (always look for the “HTTPS” extension if it’s only HTTP, better avoid it.)
