This post is part of an analysis that I have carried out during my spare time, motivated by a friend that asked me to have a look at the DDosia project related to the NoName057(16) group. The reason behind this request was caused by DDosia client changes for performing the DDos attacks. Because of that, all procedures used so far for monitoring NoName057(16) activities did not work anymore.
The new variant of bots implemented an authentication mechanism to communicate with C2 servers and their proxies. Includes IP address blocklisting, presumably to hinder the tracking of the project.
In 2023, malicious cyber actors exploited more zero-day vulnerabilities to compromise enterprise networks compared to 2022, allowing them to conduct cyber operations against higher-priority targets. In 2023, the majority of the most frequently exploited vulnerabilities were initially exploited as a zero-day, which is an increase from 2022, when less than half of the top exploited vulnerabilities were exploited as a zero-day.
Malicious cyber actors continue to have the most success exploiting vulnerabilities within two years after public disclosure of the vulnerability. The utility of these vulnerabilities declines over time as more systems are patched or replaced. Malicious cyber actors find less utility from zero-day exploits when international cybersecurity efforts reduce the lifespan of zero-day vulnerabilities.
The report shares statistics and observations from incident response practice in 2023, analyzes trends and gives cybersecurity recommendations.

he year 2023 turned out to be quite rich in events and trends in the field of cybersecurity. We witnessed a new term "white noise", the development of artificial intelligence led to increased bot activity, which significantly affected commercial companies. We detected signs of a resurgence in popularity of commercial DDoS attacks. The implementation of "remote office" technologies led to the expansion of communication channels and, as a result, increased intensity of attacks. But first things first.
DDoS Attacks by Vectors
The fourth quarter of the past year didn't bring any surprises in terms of the distribution of mixed attacks by vectors. UDP flood once again topped the list with a rate of 60.20%. IP flood came in second at 16.86%. Multivector attacks also made it into the top three with 13.36%. Overall, the distribution was as follows:
UDP flood - 60.20%
SYN flood - 7.26%
IP flood - 16.86%
Multivector attacks - 13.36%
In 2023, threat actors continued to exploit a variety of vulnerabilities — both newly discovered weaknesses and unresolved issues — to carry out sophisticated attacks on global organizations. The number of documented software vulnerabilities continued to rise, and threat actors were quick to capitalize on new vulnerabilities and leverage recent releases of publicly available vulnerability research and exploit code to target entities. However, while there was a high number of vulnerabilities released in the reporting period, only a handful actually were weaponized in attacks. The ones of most interest are those that threat actors use for exploitation. In this report, we’ll analyze the numbers and types of vulnerabilities in 2023 with a view to understanding attack trends and how organizations can better defend themselves.
Google's Threat Analysis Group (TAG) and Google subsidiary Mandiant said they've observed a significant increase in the number of zero-day vulnerabilities exploited in attacks in 2023, many of them linked to spyware vendors and their clients.
Last year, we again witnessed the power of community-driven security efforts as researchers from around the world contributed to help us identify and address thousands of vulnerabilities in our products and services. Working with our dedicated bug hunter community, we awarded $10 million to our 600+ researchers based in 68 countries.
Google on Tuesday announced that it paid out a total of $10 million through its bug bounty programs in 2023, bringing the total amount awarded by the tech giant for vulnerabilities found in its products since 2010 to $59 million.
The total paid out in 2023 is less than the $12 million handed out in 2022, but it’s still a significant amount. The money was earned last year by 632 researchers from 68 countries. The highest single reward was $113,337.
In 2023, ransomware actors intensified their operations, targeting high-profile institutions and critical infrastructure, including hospitals, schools, and government agencies. Major ransomware supply chain attacks were carried out exploiting the ubiquitous file transfer software MOVEit, impacting companies ranging from the BBC to British Airways. As a result of these attacks and others, ransomware gangs reached an unprecedented milestone, surpassing $1 billion in extorted cryptocurrency payments from victims.
Last year’s developments highlight the evolving nature of this cyber threat and its increasing impact on global institutions and security at large.
As we move further into 2024, we must be cautious (maybe even fearful!) of ransomware cases increasing even more than in previous years. Though governments around the world are taking more interest in the worldwide threat, we can see from the increase of cases that our actions have not been enough to thwart the ransomware threat. As new groups continue to form, former groups continue to evolve into new brands, and the big players continue to ramp up their efforts, we must remain vigilant and focus on our preparation and early detection capabilities.
NCSC says generative AI tools will soon allow amateur cybercriminals to launch sophisticated phishing attacks
An “unauthorized party” hijacked the cell phone number of the person running the SEC’s X account before taking over the social media feed and posting messages.
In a statement on Monday, an SEC spokesperson explained that two days after the January 9 account takeover, the government agency spoke to its telecom carrier and discovered that someone “obtained control of the SEC cell phone number associated with the account in an apparent ‘SIM swap’ attack.”
Starting January 10, 2024, multiple parties (Ivanti, Volexity, and Mandiant) disclosed the existence of a zero-day exploit chain affecting Ivanti Connect Secur…
Le CHU de Nantes est sous le coup d’une cyberattaque depuis la nuit de dimanche 14 à lundi 15 janvier 2024. Le centre hospitalier a vu son réseau internet coupé ce lundi 15 janvier, et ne peut plus recevoir et envoyer de mails en externe.
QNAP has released patches for a dozen vulnerabilities in its products, including several high-severity flaws.
This blog delves into the Phemedrone Stealer campaign's exploitation of CVE-2023-36025, the Windows Defender SmartScreen Bypass vulnerability, for its defense evasion and investigates the malware's payload.
It's been a while since I wrote an "attack of the week" post, and the fault for this is entirely mine. I've been much too busy writing boring posts about Schnorr signatures! But this week's news brings an exciting story with both technical and political dimensions: new reports claim that Chinese security agencies have developed…
Brief I may have achieved successful exploitation of a SharePoint target during Pwn2Own Vancouver 2023. While the live demonstration lasted only approximately 30 seconds, it is noteworthy that the process of discovering and crafting the exploit chain consumed nearly a year of meticulous effort and research to complete the full exploit chain.
This exploit chain leverages two vulnerabilities to achieve pre-auth remote code execution (RCE) on the SharePoint server:
Authentication Bypass – An unauthenticated attacker can impersonate as any SharePoint user by spoofing valid JSON Web Tokens (JWTs), using the none signing algorithm to subvert signature validation checks when verifying JWT tokens used for OAuth authentication.
