Active Directory Enumeration: PoweView
Active Directory Enumeration is a challenge for even some of the seasoned attackers and it is easy to miss some key components and lose the change to elevate that initial foothold that you might receive. In this article, we bring you methods that you can use to enumerate AD using PowerShell.

We can use this to check which user is reluctant to change their passwords. This can be configured to any of the property that was extracted in the previous. For this demonstration, we will be extracting the password last set property of all the users.Get-UserProperty -Properties pwdlastsethttps://1.bp.blogspot.com/--QwOofgRMds/YIcGnhyhL0I/AAAAAAAAvds/L5732d-iMUE5nvOve_iKlB845KAARkDSwCLcBGAsYHQ/s16000/6.png Find-UserFieldThere are times where there are so many users in the network that it becomes very difficult for the Domain Administrator to keep track of all users or their credentials. This is where they resort to some of the risky techniques to save the credentials information. A good example that I have seen more than ever in the real environment is saving the credentials or important information about the user in their description. This can be extracted by the use of Find-UserField with a search term. In this demonstration, we used the term pass to search for potential passwords. The user Yashika has their password written and saved in their description. This is not limited to this type of information. Lots of different data can also be extracted by using the right set of keywords such as built. This will extract the attacker from the accounts that are Built-in Accounts.

6U9PZWdrp3zs4fwCLcBGAsYHQ/s16000/8.png Invoke-UserHunterWhile enumerating the Domain, the attacker that has a targeted approach will be able to extract more data and that faster. The setup at home servers that we practice on doesn’t have a time constrain that attackers have to adhere to. In real-life red teaming assessments, if the attacker is taking their sweet time to extract data, they pose a risk to be detected and get thrown out of their initial access or even get captured. This is where some Reconnaissance comes in handy. During the Recon, the attacker can have a list of specific users that take priority to enumerate first and it is possible that those users will help the attacker to elevate access and they won’t need to enumerate other users. This reduces the time as well as the noise and logs that will be created when the attacker enumerates users. This is solved using the Invoke-UserHunter. It helps the attacker search or as its name suggests "hunt" for those specific users. It will accept usernames and if the attacker has a handy list of usernames, it will graciously accept it as well. It accepts the domain group and host lists as well. It uses a mix of Get-NetSessions and Get-NetLoggedon against every server and then compares the result against the target user set. Then again it raises the question of the amount of noise it will generate. But giving it a smaller number of usernames in the list or even giving it a single username will help the attacker reduce the noise significantly. It is worth noting that Invoke-UserHunter will run without any Administrator Privileges. Moving to the demonstration, the attacker runs the Invoke-UserHunter directly without any users or options. It will run against all users that it could find that usually is the Administrator. It can be observed that the information extracted is pretty basic but useful in the case of profiling a user.

It pretty much extracts the Domain data that includes the Forest Name, Domain Controllers with Children (that might be configured in a real environment server). Then there is the Name of the Parents with the RidRoleOwner which is a DC Object that holds the relative identifier (RID) master role and PdcRoleOwner another DC Object that holds the PDC emulator role for that specific Domain.Get-NetDomainhttps://1.bp.blogspot.com/-l5bcHj66ORQ/YIcHOHK-BpI/AAAAAAAAveY/9VOsUhp01nk5a4iTRbqqJF1XV0KF6gmEQCLcBGAsYHQ/s16000/11.png Get-NetDomain -domain “ignite.local”https://1.bp.blogspot.com/-V8JUnErR59c/YIcHXgkU6NI/AAAAAAAAvec/XurS8jIn0vErwjdBFIBg9s_0oU81BF-3QCLcBGAsYHQ/s16000/12.png Get-NetDomainControllerNext on the lineup, we have the Get-NetDomainCo[...]

Up until now, the attacker can extract the users and very little information about them. This was limited but this problem is solved using UserProperty. With it, the attacker can aim to those niche details about any particular property.

To procure information about the forest in the current user’s domain is to use Get-NetForest.Get-NetForesthttps://1.bp.blogspot.com/-i9zQuycM2fM/YIcIXX1VgbI/AAAAAAAAvfc/nlRrvk5pIWoIrA9KlyyhhCFsstsInK8cACLcBGAsYHQ/s16000/22.png Get-NetForestCatalogForests typically have different global catalogs that can help the attacker to get some precarious information about the domain.

This can be done by running Get-NetForestDomain as shown in the demonstration. Get-NetForestDomainhttps://1.bp.blogspot.com/-tt9DV_u74k0/YIcIiPHldOI/AAAAAAAAvfs/qD8GZuU6mOA9MRUOjWTPS3UZ5MLQ6CtTwCLcBGAsYHQ/s16000/24.png Get-NetLoggedonThat’s enough Forest, getting back to the users on the local or remote machine the attacker can take advantage of the NetLoggedon module. It should be noted that Administrative Rights are required to use this module. This module executes NetWkstaUserEnum Win32API call to extract the users that are currently logged on. If the attacker is in a bit of a hurry, they can enumerate all the uses that are logged on for all the machines in the domain by using the Get-DomainComputer and then running the Get-NetLoggedon on that data. This can be concatenated using a pipe. Get-DomainComputer | Get-NetLoggedonIn this demonstration, however, it is shown how to enumerate users that are loggedon on a particular machine with the help of the ComputerName option and providing the Name. Get-NetLoggedon -ComputerName DC1 Get-DomainPolicyAmongst other information, the Domain Policy of a Domain can also reveal some pretty good information. The attacker can use the Get-Domain to extract the policy of the current domain. It reads the default domain policy or the domain controller policy for the current domain or a specified domain/domain controller. To get more focus[...]

Telegram Platform Abused in ‘ToxicEye’ Malware Campaigns
https://www.blackhatethicalhacking.com/wp-content/uploads/2017/11/black-hat-locks-and-electronics.jpg Telegram Platform Abused in ‘ToxicEye’ Malware CampaignsPost Views: 134
Reading Time: 1 Minute
Hackers are leveraging the popular Telegram messaging app by embedding its code inside a remote access trojan (RAT) dubbed ToxicEye, new research has found.
A victim’s computer infected with the ToxicEye malware is controlled via a hacker-operated Telegram messaging account. The ToxicEye malware can take over file systems, install ransomware and leak data from victim’s PCs, according to researchers at Check Point Software Technologies.
Check Point said it tracked more than 130 cyberattacks in the last three months that leveraged ToxicEye, which was being managed by threat actors over Telegram. Attackers use the messaging service to communicate with their own server and exfiltrate data to it, according to a report published online Thursday.
Hackers are likely have targeted Telegram, which has more than 500 million active users across the world, as their distribution platform because of its widespread use and popularity, said Idan Sharabi, research and development manager at Check Point.
“We believe attackers are leveraging the fact that Telegram is used and allowed in almost all organizations, utilizing this system to perform cyber attacks, which can bypass security restrictions,” he said in an e-mailed statement.

Researcher point out that Telegram—which is known as a secure and private messaging service–has become even more popular during the pandemic and especially in recent months. That’s because of new privacy and data management policies instituted by WhatsApp raising concern among users and pushing them by the millions to alternative messaging platforms like Telegram.
This growing Telegram userbase has led to a corresponding surge by attackers pelting the Telegram platform with a slew of common malware, researchers report. According to Check Point, dozens of “off-the-shelf” malware samples have also been spotted targeting Telegram users.
Researchers said Telegram is an ideal way to obscure such activity because it isn’t blocked by anti-virus protections and allows attackers to remain anonymous, requiring only a mobile phone number to sign up, researchers noted. The app also allows attackers to easily exfiltrate data from victims’ PCs or transfer new malicious files to infected machines because of its communications infrastructure, and to do so remotely from any location in the world, they said. Infection ChainThe Telegram RAT attacks begin with threat actors creating a Telegram account and a dedicated Telegram bot, or remote account that allows them to interact with other users in various ways–including to chat, add people to groups or send requests directly from the input field by typing the bot’s Telegram username and a query.
See Also: Offensive Security Tool: ADFSBrute Attackers then bundle the bot token with the RAT or other chosen malware and spread the malware via email-based spam campaigns as an email attachment. For example, researchers observed attackers spreading malware via a file called “paypal checker by saint.exe,” they said.
Once a victim opens the malicious attachment, it connects to Telegram and leaves the machine vulnerable to a remote attack via the Telegram bot, which uses the messaging service to connect the victim’s device back to that attackers command-and-control server, according to the report. Post-infection attackers gain full control over a victim’s machine and can engage in a range of nef[...]

Researcher point out that Telegram—which is known as a secure and private messaging service–has become even more popular during the pandemic and especially in recent months. That’s because of new privacy and data management policies instituted by WhatsApp raising concern among users and pushing them by the millions to alternative messaging platforms like Telegram.
This growing Telegram userbase has led to a corresponding surge by attackers pelting the Telegram platform with a slew of common malware, researchers report. According to Check Point, dozens of “off-the-shelf” malware samples have also been spotted targeting Telegram users.
Researchers said Telegram is an ideal way to obscure such activity because it isn’t blocked by anti-virus protections and allows attackers to remain anonymous, requiring only a mobile phone number to sign up, researchers noted. The app also allows attackers to easily exfiltrate data from victims’ PCs or transfer new malicious files to infected machines because of its communications infrastructure, and to do so remotely from any location in the world, they said. Infection ChainThe Telegram RAT attacks begin with threat actors creating a Telegram account and a dedicated Telegram bot, or remote account that allows them to interact with other users in various ways–including to chat, add people to groups or send requests directly from the input field by typing the bot’s Telegram username and a query.
See Also: Offensive Security Tool: ADFSBrute Attackers then bundle the bot token with the RAT or other chosen malware and spread the malware via email-based spam campaigns as an email attachment. For example, researchers observed attackers spreading malware via a file called “paypal checker by saint.exe,” they said.
Once a victim opens the malicious attachment, it connects to Telegram and leaves the machine vulnerable to a remote attack via the Telegram bot, which uses the messaging service to connect the victim’s device back to that attackers command-and-control server, according to the report. Post-infection attackers gain full control over a victim’s machine and can engage in a range of nef[...]

Hacking Stories: Xbox Underground

David Pokora, from being an enthusiastic Xbox gamer to be the leader of Xbox-Underground, a gaming hacker group that hacked into gaming companies’ software and even tried to sell their own Xbox One, years before the Xbox One console was even available for selling.
Early years
Long before the Xbox was even released, in 1995, at just 3 years old, David Pokora, was mastering first-person shooter games on his parent’s computer. He fell in love with gaming and became fascinated with the idea of the “magical” control that he was able to exercise playing video-games.
He was living with his family in Mississauga, a city in Ontario, Canada. He took some coding lessons throughout elementary school, creating basic programs and he was seen as a “born programmer”. Programming captured his attention ten years later during a family trip in a village in Poland. A place without WIFI and little else to do, he started learning Visual Basic (.NET programming). The experience of learning without access to the Internet made him hooked with programming, upon returning to his home he was flawless and ready to learn more.
As David was already diving into the waters of programming, his parents bought him his first Xbox. He spent countless hours playing his favorite game, that was Halo. As time passed, he wanted to learn more about the console, and he managed to find a hacker community who hacked into Xbox, tweaking its functionalities.

Microsoft’s “kindergarten security.”
The hackers reverse-engineer the console and sniff data of communication between the processor, RAM, and the flash memory chip.
Cryptography expert, Bruce Schneier, called the discovery “kindergarten security.” Microsoft left the decryption key for booting the machine in the available memory area, this allowed downloading self-made programs on Xbox, making it transfer music, running Linux, and emulating other game consoles like Nintendo, the only necessary thing was to reflash the console.
As soon as he found out what he could do, David started tweaking things to his beloved Halo. He started chatting with hacker communities on IRC, learning things from how to change the physics of the game to fill out landscapes with digitized water or change the blue sky to rain.
The holy grail of Xbox hackers.
In 2005, the second generation of Xbox, Xbox-360, was released without the ridiculous security flaws of the previous version, ending the happy days for hackers who could no longer run code that was not approved by Microsoft. The only workaround at the time was a piece of equipment called the Xbox 360 development kit, known as Dev-kits.
Dev-kits are machines that were used by Microsoft developers to build the Xbox, they looked like regular consoles but they contained inside tools for game development, including debugging tools. This meant that in the hands of a hacker, a dev-kit could be used to manipulate the Xbox’s software and run code like an authorized programmer.
The dev-kits were extremely hard to find, Microsoft was sending them only to verified game development companies. In the mid-2000s some bankrupt companies were dumping the dev-kits in the recycling centers. This is where Rowdy Vav Cleve, a technology manager in California, and member of the hacker group Team Ava[...]

In attacks that Check Point observed, the ToxicEye RAT was used to locate and steal passwords, computer information, browser history and cookies from people’s devices; delete and transfer files or kill PC processes as well as take over a PC’s task manager; deploy a keylogger or record audio and video of the victim’s surroundings as well as steal clipboard contents; and use ransomware to encrypt and decrypt victims’ files.

Organizations also should monitor the traffic generated from PCs to Telegram accounts when the Telegram app is not installed on the systems in question, researchers said.
Researchers encourage hyper-vigilance when it comes to scrutinizing emails. Recipients need to always check the recipient line of an email that appears suspicious before engaging with it, Check Point said. If there is no recipient named or the recipient is unlisted or undisclosed, this likely indicates the email is a phishing or malicious message.
