DSoS attacks statistics and observations
DSoS attacks statistics and observations
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%

Vulnerabilities Year-in-Review: 2023
Vulnerabilities Year-in-Review: 2023
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.

From OneNote to RansomNote: An Ice Cold Intrusion - The DFIR Report
From OneNote to RansomNote: An Ice Cold Intrusion - The DFIR Report
  • In late February 2023, threat actors rode a wave of initial access using Microsoft OneNote files. In this case, we observed a threat actor deliver IcedID using this method. After loading IcedID and establishing persistence, there was no further actions, other than beaconing for over 30 days. The threat actor used Cobalt Strike and AnyDesk to target a file server and a backup server. * The threat actor used FileZilla to exfiltrate data from the network before deploying Nokoyawa ransomware.

Ransomware Diaries: Volume 1
Ransomware Diaries: Volume 1
The LockBit ransomware gang is one of the most notorious organized cybercrime syndicates that exists today. The gang is behind attacks targeting private-sector corporations and other high-profile industries worldwide. News and media outlets have documented many LockBit attacks, while security vendors offer technical assessments explaining how each occurred. Although these provide insight into the attacks, I wanted to know more about the human side of the operation to learn about the insights, motivations, and behaviors of the individuals on the other side of the keyboard. To prepare for this project, I spent months developing several online personas and established their credibility over time to gain access to the gang’s operation.

Shc Linux Malware Installing CoinMiner
The ASEC analysis team recently discovered that a Linux malware developed with Shc has been installing a CoinMiner. It is presumed that after successful authentication through a dictionary attack on inadequately managed Linux SSH servers, various malware were installed on the target system. Among those installed were the Shc downloader, XMRig CoinMiner installed through the former, and DDoS IRC Bot, developed with Perl.

Google Online Security Blog: Vulnerability Reward Program: 2023 Year in Review
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 Paid Out $10 Million via Bug Bounty Programs in 2023
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.

Ransomware Hit $1 Billion in 2023
Ransomware Hit $1 Billion in 2023
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.

Ransomware Cases Increased Greatly in 2023
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.

SEC says X account hack was due to SIM swapping
SEC says X account hack was due to SIM swapping
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.”

Attack of the week: Airdrop tracing – A Few Thoughts on Cryptographic Engineering
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…

SharePoint Pre-Auth RCE chain (CVE-2023–29357 & CVE-2023–24955) | STAR Labs
SharePoint Pre-Auth RCE chain (CVE-2023–29357 & CVE-2023–24955) | STAR Labs
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.

Active Exploitation of Two Zero-Day Vulnerabilities in Ivanti Connect Secure VPN
Active Exploitation of Two Zero-Day Vulnerabilities in Ivanti Connect Secure VPN
Volexity has uncovered active in-the-wild exploitation of two vulnerabilities allowing unauthenticated remote code execution in Ivanti Connect Secure VPN appliances. An official security advisory and knowledge base article have been released by Ivanti that includes mitigation that should be applied immediately. However, a mitigation does not remedy a past or ongoing compromise. Systems should simultaneously be thoroughly analyzed per details in this post to look for signs of a breach.
