Note: This is not to motivate you to hack and shut down websites but to provide a general idea of how the daily hacks are performed and to protect yourself from such incidents at least take some precautions.
The process of legal and authorized attempts to discover and successfully exploiting the computer system in an attempt to make the computer system more secure is called Ethical Hacking. This process includes a probe for vulnerability and providing proof of concept (POC) attacks to visualize that vulnerabilities are actually present in the system. A Good Penetration tester always provides a specific recommendation to remove the flaws in the system discovered during the penetration test. Penetration testing is also known by some other terms like
There is a term called Vulnerability Assessment which is quite similar to Penetration Testing. Vulnerability Assessment means reviewing services and systems for security issues. Many people use pen testing and vulnerability assessment interchangeably for each other but they are not the same. The penetration testing process is a step ahead of vulnerability assessment. Vulnerability Assessment only discovers flaws in the system but PT provides a way to remove those flaws as well.
2. Scanning: This phase includes the usage of tools like dialers, port scanners, network mappers, sweepers, and vulnerability scanners to scan data. Hackers are now probably seeking any information that can help them perpetrate attacks such as computer names, IP addresses, and user accounts. Now that the hacker has some basic information, the hacker now moves to the next phase and begins to test the network for other avenues of attacks. The hacker decides to use a couple of methods for this end to help map the network (i.e. Kali Linux, Maltego and find an email to contact to see what email server is being used). The hacker looks for an automated email if possible or based on the information gathered he may decide to email HR with an inquiry about a job posting.
Other options include creating a reverse TCP/IP shell in a PDF using Metasploit ( may be caught by spam filter). Looking at the event calendar they can set up an Evil Twin router and try to Man in the Middle attack users to gain access. A variant of Denial of Service attack, stack-based buffer overflows, and session hijacking may also prove to be great.
4. Maintaining Access: Once a hacker has gained access, they want to keep that access for future exploitation and attacks. Once the hacker owns the system, they can use it as a base to launch additional attacks.
In this case, the owned system is sometimes referred to as a zombie system. Now that the hacker has multiple e-mail accounts, the hacker begins to test the accounts on the domain. The hacker from this point creates a new administrator account for themselves based on the naming structure and tries and blends in. As a precaution, the hacker begins to look for and identify accounts that have not been used for a long time. The hacker assumes that these accounts are likely either forgotten or not used so they change the password and elevate privileges to an administrator as a secondary account in order to maintain access to the network. The hacker may also send out emails to other users with an exploited file such as a PDF with a reverse shell in order to extend their possible access. No overt exploitation or attacks will occur at this time. If there is no evidence of detection, a waiting game is played letting the victim think that nothing was disturbed. With access to an IT account, the hacker begins to make copies of all emails, appointments, contacts, instant messages and files to be sorted through and used later.
Most of the time is spent on the Reconnaissance process. Time spend gets reduced in upcoming phases. The inverted triangle in the diagram represents a time to spend in subsequent phases that get reduced.
If you think you are compromised, inform the service providers and if you are confirmed then you must report it to the cybercrime department. These days such incidents are being taken seriously. Be safe and refrain from becoming the target!!
It seems `chronod` plays a crucial role in widget functionality on macOS. My issues, in particular, were related to the Tesla widget. While a restart would have likely solved any issues related to this, I wanted to dive a bit deeper to help the next guy understand more about `chronod`. Hope this helps anyone struggling with widget issues!
I'm not a high-level person here, but my research indicates chronod is related to Widgets in macOS Sonoma. I got a popup from macOS firewall asking if I wanted to allow incoming connections to chronod. I found some Reddit posts that say it has to do with Widgets (apparently in iOS and macOS).
The bottom line is: this is a macOS process; you can safely allow chrond connections in any firewall you're running on your Mac. You can dis-allow chrond, but it will likely break some functions related to widgets (and probably some other things).
Lately, the better sources for macOS malware have been cracked apps, and obviously-sketchy downloads. The biggest mess lately has been some persistent adware that the built-in anti-malware is blocking, but is not yet removing. (details)
There have been previous cases with these add-on security apps where the app mis-detected and tried to delete parts of macOS itself. The built-in macOS anti-malware then detected and blocked these (erroneous) deletion attempts. The add-on security vendor eventually pushed out a fix for that false positive.
Don't "Allow" a program/daemon access unless you know with certitude exactly what it is. Err on the side of caution because you can always "Allow" permissions to a legitimate program after the fact which is much easier and less painful than canceling your credit card for fraud or filing a police report for identify theft.
Bad actors often create malicious programs that use legitimate and common program names to trick users into granting access. What's more difficult to fake are security signatures for legit publishers so programs such as Norton check and block programs that aren't signed. For instance "chronod" is often used by bad actors aka hackers to intercept browser data, e.g. credentials, while connected to a public wifi or hotel network that's outside of your corporate or home networks.
Today's modern macOS and even Windows include powerful built-in anti-malware capabilities. Unless you are a high-profile target for bad-actors like government security services, or you frequent very sketchy websites, you don't need any 3rd party applications. If you must have one, Malwarebytes is probably the best option, and it's designed for most people (not tech experts).
Trying to make sense of what is happening on a modern computer, iPhone, or your network takes expertise and knowledge that most people simply don't have. In this case, Norton is showing you info that you have no way to understand and make an informed decision about--that's why many people ended up here. I suspect this is part of their marketing strategy. The best advice is "get rid of 3rd party AV, and just let macOS do it's thing."
And yes chrond is part of macOS; it can't be removed or stopped. If you block it, you are breaking macOS. It is possible for malware to pretend to be chrond, but this is VERY unlikely. But you can check the program's signature and verify it is signed by Apple.
ASM consists of four core processes: Asset discovery, classification and prioritization, remediation and monitoring. Again, because the size and shape of the digital attack surface changes constantly, the processes are carried out continuously, and ASM solutions automate these processes whenever possible. The goal is to arm security teams with complete and current inventory of exposed assets and to accelerate response to the vulnerabilities and threats that present the greatest risk to the organization.
Asset discovery automatically and continuously scans for and identifies internet-facing hardware, software and cloud assets that could act as entry points for a hacker or cybercriminal trying to attack an organization. These assets can include:
Because security risks in the organization's attack surface change any time new assets are deployed or existing assets are deployed in new ways, both the inventoried assets of the network and the network itself are continuously monitored and scanned for vulnerabilities. Continuous monitoring enables ASM to detect and assess new vulnerabilities and attack vectors in real time, and alert security teams to any new vulnerabilities that need immediate attention.
A zero trust approach requires that all users, whether outside or already inside the network, be authenticated, authorized and continuously validated in order to gain and maintain access to applications and data.

Merhabalar, Windows API kullanarak bir processin sahibini değiştirmeye alışıyorum. Program ıktısında sıkıntısız alıştığı yazıyor ancak processin sahibini kontrol ettiğimde değişmemiş halde gryorum. Bu sorunun zm nedir? Kodu bırakıyorum.
Ben bir kullanıcı seviyesindeyim, bir process ağırıyorum, sonra ağırdığım process başka bir etki alanında bunu alıp bir başka yetki seviyesine ve etki alanına ekiyorum ki buna yetkim var mı emin değiliz.
Sylediklerinize gre ne demek istediğimi tam anlamamışsınız. Yapmak istediğim program tam olarak şu: Program, ynetici yetkisiyle (en azından bizim programın alabileceği en yksek yetkiyle), setiğimiz terminate edilemeyen 3. taraf bir processin sahipliğini değiştirerek bu processi terminate edecek. Burada işletim sistemine aykırı bir şey yapmak istemiyorum aslında, dll injection gibi yntemleri kullanmadan windows api ile yapılabileceğini dşnyordum. Haksız mıyım? Eğer windows api ile bunu yapmak mmkn değilse araştırabileceğim bir yntem nerir misiniz?
