Microsoft would like to thank our industry colleagues at Volexity and Dubex for reporting different parts of the attack chain and their collaboration in the investigation. Volexity has also published a blog post with their analysis.
It is this level of proactive communication and intelligence sharing that allows the community to come together to get ahead of attacks before they spread and improve security for all. HAFNIUM primarily targets entities in the United States across a number of industry sectors, including infectious disease researchers, law firms, higher education institutions, defense contractors, policy think tanks, and NGOs.
HAFNIUM has previously compromised victims by exploiting vulnerabilities in internet-facing servers, and has used legitimate open-source frameworks, like Covenant , for command and control. Microsoft is providing the following details to help our customers understand the techniques used by HAFNIUM to exploit these vulnerabilities and enable more effective defense against any future attacks against unpatched systems.
CVE is an insecure deserialization vulnerability in the Unified Messaging service. Insecure deserialization is where untrusted user-controllable data is deserialized by a program. This requires administrator permission or another vulnerability to exploit. CVE is a post-authentication arbitrary file write vulnerability in Exchange. Web shells potentially allow attackers to steal data and perform additional malicious actions that lead to further compromise.
HAFNIUM operators were also able to download the Exchange offline address book from compromised systems, which contains information about an organization and its users. Our blog, Defending Exchange servers under attack , offers advice for improving defenses against Exchange server compromise.
Customers can also find additional guidance about web shell attacks in our blog Web shell attacks continue to rise. The below sections provide indicators of compromise IOCs , detection guidance, and advanced hunting queries to help customers investigate this activity using Exchange server logs, Azure Sentinel, Microsoft Defender for Endpoint, and Microsoft Defender.
We encourage our customers to conduct investigations and implement proactive detections to identify possible prior campaigns and prevent future campaigns that may target their systems. Your resident antivirus suddenly starts reporting that backdoors or trojans have been detected, even if you have not done anything out of the ordinary.
Although hacker attacks can be complex and innovative, many rely on known trojans or backdoors to gain full access to a compromised system. If the resident component of your antivirus is detecting and reporting such malware, this may be an indication that your system can be accessed from outside.
After breaking into a system, a hacker usually attempts to secure access by planting a backdoor in one of the daemons with direct access from the Internet, or by modifying standard system utilities which are used to connect to other systems. In all cases, it is a good idea to maintain a database of checksums for every system utility and periodically verify them with the system offline, in single user mode.
Look for any suspicious usernames in the password file and monitor all additions, especially on a multi-user system. Opening a backdoor in a Unix system is sometimes a matter of adding two text lines.
Closely monitor these two files for any additions which may indicate a backdoor bound to an unused or suspicious port.

For all other countries Global. Aircrack-ng is a decryption software that aims to assess the network security of a Wi-Fi network by evaluating the vulnerabilities of the passwords that are used to secure it.
Passwords with low-to-medium complexity can easily be cracked via this software or Linux utility. Enroll in our Cybersecurity Course and gain valuable skills and competencies by deploying distinct information security structures for companies.
Kiuwan is among the most used Ethical Hacking tools in software development. Upon finding the parts of the code that could potentially make the software unsecure in practice, the development team can patch it up after finding out the workarounds or alternatives for it.
Netsparker detects security flaws, such as SQL injection vulnerabilities and cross-site scripting, in web applications and APIs. The main advantage of Netsparker is that it is percent accurate with its results, eliminating the chances of false positives.
During security assessments, this helps a tester to avoid manually testing cases to verify whether those flaws actually exist or not. Nikto is an open-source tool that is used to scan web servers to detect vulnerabilities.
It detects dangerous files, outdated server components, etc. Nikto is primarily used as a penetration testing tool. Burp Suite is an advanced web vulnerability scanner with three versions, Community free , Enterprise, and Professional.
You only get access to the manual tools with the Community edition, but with the paid versions, you get access to a higher number of features. John the Ripper is one of the best password-cracking utilities in the market.
It gives you tons of customization options according to the approach that you want to go with for the cracking job. The primary job of John the Ripper is to test the strength of an encrypted password. Its main advantage is the speed at which it can crack passwords. Metasploit provides you with a remote machine on which you can test your scripts and hacks to verify their success and strength. The framework gives hackers an idea of how to alter or upgrade the hacking software to ensure execution.
It helps them to understand the security vulnerabilities of various systems due to the cross-platform support. This framework is highly favored in the development of security tools and utilities. Ettercap has cross-platform support, so the operating systems of the target systems are not a factor in the sniffing process.
As a network administrator, these plugins can also be used to ensure content filtering and network or host analysis. Hope you enjoyed reading our blog on the Best Hacking Tools and Software and it gave you many valuable insights on various tools and programs.
