Mykhailo Dovhanych, 21, our Pentester has become a local celebrity. He made the digital world a bit safer by discovering a Zero-day vulnerability and getting his first CVE. We asked him a couple of questions to learn more about this exciting story:
UnderDefense: What is the official name of your position in the company?
Mykhailo: I’m a Penetration Tester, but personally, I prefer to call it Red Team Operator (laughing).
UnderDefense: When did you decide that you want to work in the CyberSec industry? Why?
Mykhailo: I`ve been into cybersecurity since 2019 when a couple of my friends decided to go to military universities. I planned to join them, but then I realized that cyberspace is the “5th field” of war, the most interesting for me. I felt like I could definitely make a contribution there. So I made the decision to advance in Offensive Security.
UnderDefense: What software was this vulnerability found in?
Mykhailo: I found it in Pi-hole. Pi-hole is a free, open-source software for Linux that acts as a DNS sinkhole and ad blocker. It is designed to run on a Raspberry Pi, but can also be installed on other Linux-based systems. Pi-hole blocks ads by routing DNS queries for known ad-serving domains to a “black hole” effectively preventing ads from appearing on devices that use it as their DNS server.
UnderDefense: Who uses Pi-hole? How many people could be affected?
Mykhailo: These are individuals and organizations that want to block unwanted ads and trackers on their network, including homes, small businesses, and schools. Also, it is used by individuals who want more control over their privacy and security when browsing the internet. There is no exact data regarding Pi-hole installs and active users, but approximately hundreds of thousands could have been affected, possibly even more than half a million.
UnderDefense: What is the nature of the vulnerability you found?
Mykhailo: The vulnerability is that attackers could access information about domains from these blacklists created by the administrator. These blacklists contain confidential information that should not be disclosed. Since tracking domains are constantly changing, it’s not easy to record all of them and keep the blacklists updated. So updated lists of such domains are sold on the internet and you can buy them for a few dollars. In this particular case, the client who buys and implements such a list is in danger. Attackers can obtain these lists for free by exploiting the vulnerability. When we announced it to the developer, it had a “Zero Day” status, meaning that all versions were vulnerable.
UnderDefense: Was this vulnerability fixed?
Mykhailo: With the help of search engines Shodan, ZoomEye, and special Google Dorks, it was possible to select publicly available DNS servers and get all blocked domains from them. Currently, there is an updated version of the Pi-Hole Admin Panel without this vulnerability.

Having an efficient password policy is critical to the cybersecurity of companies. Since using easy-to-identify passwords is a way to facilitate scams by malicious actors. For the same reason, repeating passwords is a risky practice.
In 2021, more than 8.4 billion passwords from people all over the world were leaked and posted under the name ‘rock you 2021‘ in an online forum. What did they have in common? They used between 6 and 20 characters, without spaces, numbers, or symbols.
Other characteristics of easy-to-steal passwords are: using birthday or algorithms with repeated numbers, proper names, numerical combinations, and the word Brazil are also often found in leaked passwords of Brazilian users, in addition to the sequence 123456.
We have prepared this article especially to help you keep your company protected. In it, we will propose positive actions for an effective password policy. They are as follows:
Read it until the end!
We know hackers take advantage of the weakness of corporate passwords in most cyber-invasions.
Therefore, regardless of the size or industry of an organization, it is essential to have a secure password policy. After all, by adopting it, one avoids invasions that generate inconvenience and financial losses, in addition to preventing the company’s credibility from coming into question.
In practice, the password policy establishes rules to be followed by the entire team, ensuring the adoption of security requirements when creating passwords for accessing corporate devices and systems.
In the next topic, we cover some criteria you should adopt when establishing a password policy for your business.
You now understand the importance of creating a secure password policy for your company. Now, let’s show you how this can be done. Keep reading our text!
It is believed that using the same password in different applications and services can facilitate the access of malicious users, and when we reduce the number of accesses with the same password, we also reduce the possibilities that they are shared and available for access by third parties.
However, the usefulness of this measure has been questioned. Microsoft itself stopped asking for the periodic change of passwords, considering this method useless. According to this report in Isto É Dinheiro, Aaron Margosis, a cybersecurity consultant at Microsoft, stated it is necessary to change the password only if it is stolen.
Despite this debate, the periodic change of passwords has still been recommended, for this reason, we explain about software that emits alerts when it is time to change them in the following topic.
There is specific software that warns about the need to change passwords. They work as follows: when you try to access the computer after some time, you see a pop-up, warning you about the need to change your password to proceed. If you don’t, you will not be able to access the system.
These pieces of software are very useful because, over time, it is very common for people to get comfortable and fail to change their passwords within a certain time.
Blocking accounts is a very important practice that prevents access after a certain number of attempts. This feature prevents the user from trying to access a system by testing multiple passwords until they reach their goal. This practice is known as brute force and is often used by malicious attackers to gain unauthorized access to these systems.
To get a sense of the importance this feature has, it is widely used by e-mail services and various websites.
If you are at the head of an organization, you should know that in addition to investing in technology to ensure information security, you need to train your employees through awareness and training to make it possible to identify and avoid threats.
Many people are unaware of the risks involved in accessing corporate systems. In these cases, it is necessary to introduce good practices and enforce them to prevent cyberattacks, including password theft.
It is also important that these pieces of training are constant, since technology advances every day, as well as the techniques used by malicious agents.
If someone manages to steal your password from social media, for example, it is very likely they will test it on your other services, causing much more damage if you use the same password to connect to different online platforms.
Therefore, when establishing a password policy, remember to recommend that your employees have a different password for each online environment they access.
It is not enough to use passwords to access systems. It is necessary to resort to strategies that make it possible to increase the security level of the passwords used. After all, hackers often analyze users and attempt the invasion by testing obvious possibilities such as birthdates, relatives’ names, and short words.
In these cases, we recommend using a minimum number of digits, combining uppercase and lowercase letters, numbers, and symbols.
If you follow the fifth and sixth tips in this article, your employees will have to remember a lot of complex passwords, which can be quite difficult. That’s where a password management solution comes into play.
This feature is capable of storing passwords, facilitating the work of users, who only need to remember the password used to access this system. What’s more, password managers still suggest codes that are unlikely to be discovered.
Of course, like all other apps, they can be breached. Therefore, it is essential to use an extremely secure master password.
One of the ways to create a secure password policy is to adopt multifactor authentication (MFA). This solution brings together different mechanisms to prevent intrusions, which are:
But remember an important detail: in the multifactor authentication, the mechanisms must be independent of each other to guarantee the protection of a system. This means that if one of the factors gives access to the other, your organization is not protected.

國際資安大廠ESET發現駭客對烏克蘭發動的網路攻擊中所使用的惡意程式,包括資料刪除程式HermeticWiper、IssacWiper,以及勒索軟體HermeticRansom
在俄羅斯攻擊烏克蘭前一日(2月23日),ESET已經偵測到對烏克蘭基礎架構的資訊戰活動,而偵測到的一波攻擊包括3項元素,分別是HermeticWizard經由WMI(Windows Management Instrumentation)和SMB協定散布的HermeticWiper,以及用Go語言撰寫的勒索軟體HermeticRansom,這波攻擊至少影響烏克蘭5個組織的數百臺系統。
而在不到24小時內,ESET又發現另一隻資料刪除程式,他們將之命名為IssacWiper,IssacWiper目前的樣本是在Windows DLL或EXE檔中發現,不具程式碼簽章憑證。研究人員推測IssacWiper攻擊者可能是利用Imapcket等工具在受害者網路內橫向移動,此外,幾臺受害機器中也看到遠端存取木馬(RAT)RemCom,可能是和IssacWiper同時植入。從其編譯時戳來看,最早可追溯到2021年10月19日,因此研究人員相信IssacWiper可能已被用於幾個月前的攻擊。
這是繼一月的WisperGate以來,第三隻攻擊烏克蘭的資料刪除程式。
這幾波攻擊來源目前尚無法得知,主要是因為HermeticWiper、HermeticWizard和HermeticRansom與ESET過去所知的惡意程式相似性甚低,故未能找到IssacWiper的來源,或是它最初的攻擊管道。
目前研究人員還在分析兩者之間關聯性,但一些未受HermeticWiper影響的機構卻有見到IssacWiper;就程式碼相似性來看,IssacWiper和HermeticWiper的程式碼幾乎沒重疊,也較為粗糙;HermeticWiper相當兇惡,濫用硬碟分割軟體EaseUS Partition Master的合法驅動程式(如下圖所示),先毁損資料再將受害電腦重新開機。在研究人員分析的一項案例中,這隻程式是經由預設的網域GPO植入系統,意謂攻擊者可能已經接管受害機構的AD伺服器。

相較而言,攻擊者釋出的新版IssacWiper有除錯紀錄,顯示舊版未能將受害電腦資料刪除掉,攻擊者試圖了解原因所在。
研究人員相信,就目前烏克蘭危機來看,不論是烏克蘭或支持它的國家,都有持續遭遇網路攻擊的風險。
