If the United States wishes to compete in cyberspace, it must compete against China to secure its offensive cyber supply chain.
Strategic competition between the United States and China has long played out in cyberspace, where offensive cyber capabilities, like zero-day vulnerabilities, are a strategic resource. Since 2016, China has been turning the zero-day marketplace in East Asia into a funnel of offensive cyber capabilities for its military and intelligence services, both to ensure it can break into the most secure Western technologies and to deny the United States from obtaining similar capabilities from the region. If the United States wishes to compete in cyberspace, it must compete against China to secure its offensive cyber supply chain.
This report is the first to conduct a comparative study within the international offensive cyber supply chain, comparing the United States’ fragmented, risk-averse acquisition model with China’s outsourced and funnel-like approach.

ATO’s 76th summit, which will be held June 24-25, 2025, in The Hague, Netherlands, comes at a time as the alliance’s member countries grapple with a rapidly changing global security dynamic. Russia continues to press on with its war campaign in Ukraine despite efforts to achieve a cease fire. Deep questions remain over the U.S. military commitment to Ukraine and if the U.S. would assist Europe if a conflict surfaced as required under Article 5 of NATO’s founding treaty. Israel undertook bombing strikes against Iran on the pretence that Iran was edging close to building viable nuclear weapons, which was followed by U.S. airstrikes. Since the previous summit, the leaders of European NATO countries have shown a dramatic change in rhetoric regarding the need to take on greater responsibility for security on the European continent, particularly as it pertains to increases in defense spending and military assistance to Ukraine. With an anticipated ambitious agenda, evidence of a clear rift in transatlantic relations and the alliance’s global super power distracted with other priorities, the summit could be hampered by disruption and division. This environment is ripe for cyber threats, prompting NATO member states to be on the look out for activity that could impact critical infrastructure entities. These threats could come from ideological and politically motivated attackers, who may seek to draw attention through distributed denial-of-service (DDoS) attacks, data leaks and website defacements affecting NATO nations. This blog, which draws on Intel 471’s Cyber Geopolitical Intelligence, will outline the issues at hand at the summit, the challenges facing NATO and look at the possible cyber threats.
Imperva’s Offensive Security Team discovered CVE-2025-49763, a high-severity vulnerability (CVSS v3.1 estimated score: 7.5) in Apache Traffic Server’s ESI plugin that enables unauthenticated attackers to exhaust memory and potentially crash proxy nodes. Given ATS’s role in global content delivery[1], even a single node failure can black-hole thousands of sessions. Organizations should urgently upgrade to version 9.2.11 or 10.0.6 and enforce the new inclusion-depth safeguard.
Why reverse‑proxy servers matter
Every web request you make today almost certainly travels through one or more reverse‑proxy caches before it reaches the origin application. These proxies:
This vulnerability can be exploited via two different ways:
A threat actor could exploit an Edge Side Include injection and recursively inject the same page over and over again.
exploitation via esi injection
A threat actor could also host a malicious server next to a target, behind a vulnerable traffic server proxy and take down the proxy by triggering the ESI request avalanche. (see Fig 2).
exploitation via malicious error
This results in a full denial of service on edge proxy nodes, triggered remotely without requiring authentication.
Elastic Security Labs has observed the ClickFix technique gaining popularity for multi-stage campaigns that deliver various malware through social engineering tactics.
Our threat intelligence indicates a substantial surge in activity leveraging ClickFix (technique first observed) as a primary initial access vector. This social engineering technique tricks users into copying and pasting malicious PowerShell that results in malware execution. Our telemetry has tracked its use since last year, including instances leading to the deployment of new versions of the GHOSTPULSE loader. This led to campaigns targeting a broad audience using malware and infostealers, such as LUMMA and ARECHCLIENT2, a family first observed in 2019 but now experiencing a significant surge in popularity.
This post examines a recent ClickFix campaign, providing an in-depth analysis of its components, the techniques employed, and the malware it ultimately delivers.

According to MITRE, Browser-in-the-Middle (BitM) is an attack where “an adversary exploits the inherent functionalities of a web browser, in order to establish an unnoticed remote desktop connection in the victim’s browser to the adversary’s system.” This attack has been used by many attackers to trick victims into unknowingly entering credentials and providing sensitive information on an attacker controlled window. The attack was first disclosed in a paper by researchers from the University of Salento in 2021, and we have seen many cases of BitM being used in the wild since then.
However, one key flaw of the BitM attack is that it still requires the victim to land on a malicious site and perform an action to open up the noVNC pop-up window. As the parent window still has a malicious URL in its address bar, this will likely raise suspicion among more security aware users at the point of credential entry.
SquareX’s research team has observed multiple instances of the browser’s FullScreen API being exploited to address this flaw by displaying a fullscreen BitM window that covers the parent window’s address bar, as well as a limitation specific to Safari browsers that makes fullscreen BitM attacks especially convincing. The article below will recap how BitM attacks work, explore the Fullscreen API requirements and why Safari browsers are particularly vulnerable to fullscreen BitM attacks.
Traditional Browser-in-the-Middle (BitM) Attacks
To illustrate how a typical BitM attack works, we will use a real attack that targeted Counter-Strike 2 gamers. Incentivized by cryptocurrency and skin giveaways, victims were tricked into entering their Steam credentials. These compromised accounts were then sold on the black market for up to $300,000. Here is how it works:
Note: The case study below actually used the Browser-in-the-Browser (BitB) technique, where instead of using remote desktop, the attackers uses HTML, CSS and JavaScript most commonly to mimic login pop-ups of popular SaaS or Single Sign-On (SSO) services. We chose this example as it is a well documented attack and because the social engineering and principles behind this attack can also be used in BitM attacks.
AhnLab SEcurity intelligence Center (ASEC) recently identified a phishing malware being distributed in Scalable Vector Graphics (SVG) format. SVG is an XML-based vector image file format commonly used for icons, logos, charts, and graphs, and it allows the use of CSS and JS scripts within the code. In November 2024, the ASEC Blog introduced SVG […]
Discover how to intercept data stolen by cybercriminals via Telegram bots and learn to use it to clarify related threat landscape.
While analyzing malware samples uploaded to ANY.RUN’s Interactive Sandbox, one particular case marked as “phishing” and “Telegram” drew the attention of our security analysts.
Although this analysis session wasn’t attributed to any known malware family or threat actor group, the analysis revealed that Telegram bots were being used for data exfiltration. This led us to apply a message interception technique for Telegram bots, previously described on the ANY.RUN blog.
The investigation resulted in a clear and practical case study demonstrating how intercepting Telegram bot communications can aid in profiling the threat actor behind a relatively obscure phishing campaign.
Key outcomes of this analysis include:
Examination and technical analysis of a lesser known phishing campaign
Demonstration of Telegram API-based data interception techniques
Collection of threat intelligence (TI) indicators to help identify the actor
Recommendations for detecting this type of threat
Google Threat Intelligence Group (GTIG) has identified a new piece of malware called LOSTKEYS, attributed to the Russian government-backed threat group COLDRIVER (also known as UNC4057, Star Blizzard, and Callisto). LOSTKEYS is capable of stealing files from a hard-coded list of extensions and directories, along with sending system information and running processes to the attacker. Observed in January, March, and April 2025, LOSTKEYS marks a new development in the toolset of COLDRIVER, a group primarily known for credential phishing against high-profile targets like NATO governments, non-governmental organizations (NGOs), and former intelligence and diplomatic officers. GTIG has been tracking COLDRIVER for many years, including their SPICA malware in 2024.
COLDRIVER typically targets high-profile individuals at their personal email addresses or at NGO addresses. They are known for stealing credentials and after gaining access to a target’s account they exfiltrate emails and steal contact lists from the compromised account. In select cases, COLDRIVER also delivers malware to target devices and may attempt to access files on the system.
Recent targets in COLDRIVER’s campaigns have included current and former advisors to Western governments and militaries, as well as journalists, think tanks, and NGOs. The group has also continued targeting individuals connected to Ukraine. We believe the primary goal of COLDRIVER’s operations is intelligence collection in support of Russia’s strategic interests. In a small number of cases, the group has been linked to hack-and-leak campaigns targeting officials in the UK and an NGO.
To safeguard at-risk users, we use our research on serious threat actors like COLDRIVER to improve the safety and security of Google’s products. We encourage potential targets to enroll in Google's Advanced Protection Program, enable Enhanced Safe Browsing for Chrome, and ensure that all devices are updated.
Overview: Check Point researchers have identified a new phishing campaign that exploits Microsoft’s “Dynamics 365 Customer Voice,” a customer relationship
Overview:
Check Point researchers have identified a new phishing campaign that exploits Microsoft’s “Dynamics 365 Customer Voice,” a customer relationship management software product. It’s often used to record customer calls, monitor customer reviews, share surveys and track feedback.
Microsoft 365 is used by over 2 million organizations worldwide. At least 500,000 organizations use Dynamics 365 Customer Voice, including 97% of Fortune 500 companies.
In this campaign, cyber criminals send business files and invoices from compromised accounts, and include fake Dynamics 365 Customer Voice links. The email configuration looks legitimate and easily tricks email recipients into taking the bait.
As part of this campaign, cyber criminals have deployed over 3,370 emails, with content reaching employees of over 350 organizations, the majority of which are American. More than a million different mailboxes were targeted.
Affected entities include well-established community betterment groups, colleges and universities, news outlets, a prominent health information group, and organizations that promote arts and culture, among others.
Today it was discovered that an unknown actor had managed to exploit a vulnerability in Lockbit’s PHPMyAdmin instance (on their console onion site). Apparently they were running PHP 8.1.2 which is vulnerable to an RCE CVE-2024-4577. Which uhh… lol? It probably would have been prudent to do a post-paid penetration test on their own infrastructure at some point.
Further compounding the unfortunate situation, the actor was able to dump their database. This contained, as stated by Bleeping Computer, a number of tables such as bitcoin addresses, data about their build system such as bespoke builds for affiliates, A ‘chats’ table containing negotiation messages, which we’ll go through in a later post. And finally, of interest today, the usernames and passwords of LockBit agents using the console.
Of special importance, making our work markedly easier, these passwords were not hashed. Which sure is a choice, as an organization that performs ransomware attacks.
The vast majority of the passwords in this table as reasonably secure; it’s not solely hilariously weak credentials, but there still are a number that display poor security hygiene.
The weak passwords
Before going into my standard analysis, I’ll list off all of the weak passwords in question, and then we’ll go through the statistics of the whole set. The fun to highlight passwords:
DragonForce ransomware group is targeting major UK retailers. Learn about this evolving threat and what steps can be taken to mitigate risk.
In recent weeks, the DragonForce ransomware group has been targeting UK retailers in a series of coordinated attacks causing major service disruptions. Prominent retailers such as Harrods, Marks and Spencer, and the Co-Op have all reported ongoing incidents affecting payment systems, inventory, payroll and other critical business functions.
DragonForce has previously been attributed for a number of notable cyber incidents including attacks on Honolulu OTS (Oahu Transit Services), the Government of Palau, Coca-Cola (Singapore), the Ohio State Lottery, and Yakult Australia.
In this post, we offer a high-level overview of the DragonForce group, discuss its targeting, initial access methods, and payloads. We further provide a comprehensive list of indicators and defensive recommendations to help security teams and threat hunters better protect their organizations.
Background
DragonForce ransomware operations emerged in August 2023, primarily out of Malaysia (DragonForce Malaysia). The group originally positioned itself as a Pro-Palestine hacktivist-style operation; however, over time their goals have shifted and expanded.
The modern-day operation is focused on financial gain and extortion although the operation still targets government entities, making it something of a hybrid actor, both politically aligned and profit-motivated. The group operates a multi-extortion model, with victims threatened with data leakage via the group’s data leak sites, alongside reputational damage.
Recent DragonForce victims have included government institutions, commercial enterprises, and organizations aligned with specific political causes. The group is also known to heavily target law firms and medical practices. Notably, the group has targeted numerous entities in Israel, India, Saudi Arabia, and more recently several retail outlets in the United Kingdom.
Some components of the UK retail attacks have been attributed to an individual affiliated with the loose threat actor collective ‘The Com’, with claims that members are leveraging DragonForce ransomware. Our assessment indicates that the affiliate in question exhibits behavioral and operational characteristics consistent with those previously associated with The Com. However, due to the lack of strong technical evidence and shifting boundaries of The Com, that attribution remains inconclusive and subject to further analysis.

The backend of a phishing threat actor operating at scale
The scam industry has seen explosive growth over the past several years. The types of scams and methods used are constantly evolving as scammers adapt their techniques to continue their activities. They often capitalise on new technologies and target areas where our societies have yet to build mechanisms to protect themselves.
This story begins in December 2023 when people all over the world – including a large portion of the Norwegian population - started to receive text messages about packages waiting for them at the post office. The messages would come in the form of an SMS, iMessage or RCS message. What we were witnessing was the rise of a scam technique known as smishing or SMS phishing.
Such messages have one thing in common: they impersonate a brand that we trust to create a credible context for soliciting some kind of personal information, thus tricking us into willfully giving away our information.
Some scams are easier to spot than others. Spelling errors, poor translations, strange numbers or links to sketchy domains often give them away. But even tell-tale signs can be easy to miss on a busy day. When a large number of people are targeted, some will be expecting a package. And the tactic is obviously working. If it wasn’t worth their while, the scammers wouldn’t have invested so much time, money and effort.
StealC V2 enhances information stealing, introduces RC4 encryption, and provides a new control panel for more targeted payloads.
StealC is a popular information stealer and malware downloader that has been sold since January 2023. In March 2025, StealC version 2 (V2) was introduced with key updates, including a streamlined command-and-control (C2) communication protocol and the addition of RC4 encryption (in the latest variants). The malware’s payload delivery options have been expanded to include Microsoft Software Installer (MSI) packages and PowerShell scripts. A redesigned control panel provides an integrated builder that enables threat actors to customize payload delivery rules based on geolocation, hardware IDs (HWID), and installed software. Additional features include multi-monitor screenshot capture, a unified file grabber, and server-side brute-forcing for credentials.
This blog post focuses on the recent changes in StealC V2, describing the improvements in payload delivery, encryption, control panel functionality, and the updated communication protocol.
Key Takeaways
Another day, another edge device being targeted - it’s a typical Thursday!
In today’s blog post, we’re excited to share our previously private analysis of the now exploited in-the-wild N-day vulnerabilities affecting SonicWall’s SMA100 appliance. Over the last few months, our client base has fed us rumours of in-the-wild exploitation of SonicWall systems, and thus, this topic has had our attention for a while.
Specifically, today, we’re going to be analyzing and reproducing:
CVE-2024-38475 - Apache HTTP Pre-Authentication Arbitrary File Read
Discovered by Orange Tsai
Although this is a CVE attached to the Apache HTTP Server, it is important to note that due to how CVEs are now assigned, a seperate CVE will not be assigned for SonicWall's usage of the vulnerable version.
This makes the situation confusing for those responding to CISA's KEV listing - CISA is referring to the two vulnerabilities in combination being used to attack SonicWall devices.
You can see this evidenced in SonicWall's updated PSIRT advisory: https://psirt.global.sonicwall.com/vuln-detail/SNWLID-2024-0018
CVE-2023-44221 - Post-Authentication Command Injection
Discovered by "Wenjie Zhong (H4lo) Webin lab of DBappSecurity Co., Ltd”
As of the day this research was published, CISA had added these vulnerabilities to the Known Exploited Vulnerabilities list.
Do you know the fun things about these posts? We can copy text from previous posts about edge devices:
Malware Analysis Report - LockBit Ransomware v4.0
In this blog post, I’m going over my analysis for the latest variant of LockBit ransomware - version 4.0. Throughout this blog, I’ll walk through all the malicious functionalities discovered, complete with explanations and IDA screenshots to show my reverse engineering process step by step. This new version of LockBit 4.0 implements a hybrid-cryptography approach, combining Curve25519 with XChaCha20 for its file encryption scheme.
This version shares similarities with the older LockBit Green variant that is derived from Conti ransomware. While the multi-threading architecture seems more streamlined than previous versions, it still delivers an encryption speed that outpaces most other ransomware families.
As always, LockBit is still my most favorite malware to look at, and I certainly enjoyed doing a deep dive to understand how this version works.
This Google Threat Intelligence Group report presents an analysis of detected 2024 zero-day exploits.
Google Threat Intelligence Group (GTIG) tracked 75 zero-day vulnerabilities exploited in the wild in 2024, a decrease from the number we identified in 2023 (98 vulnerabilities), but still an increase from 2022 (63 vulnerabilities). We divided the reviewed vulnerabilities into two main categories: end-user platforms and products (e.g., mobile devices, operating systems, and browsers) and enterprise-focused technologies, such as security software and appliances.
Vendors continue to drive improvements that make some zero-day exploitation harder, demonstrated by both dwindling numbers across multiple categories and reduced observed attacks against previously popular targets. At the same time, commercial surveillance vendors (CSVs) appear to be increasing their operational security practices, potentially leading to decreased attribution and detection.
We see zero-day exploitation targeting a greater number and wider variety of enterprise-specific technologies, although these technologies still remain a smaller proportion of overall exploitation when compared to end-user technologies. While the historic focus on the exploitation of popular end-user technologies and their users continues, the shift toward increased targeting of enterprise-focused products will require a wider and more diverse set of vendors to increase proactive security measures in order to reduce future zero-day exploitation attempts.
Cisco Talos discovered a sophisticated attack on critical infrastructure by ToyMaker and Cactus, using the LAGTOY backdoor to orchestrate a relentless double extortion scheme.
In this two-part series, SpiderLabs explores the malicious traffic associated with Proton66, revealing the extent and nature of these attacks.
Mass scanning and exploit campaigns targeting multiple sectors
Starting from January 8, 2025, SpiderLabs observed an increase in mass scanning, credential brute forcing, and exploitation attempts originating from Proton66 ASN targeting organizations worldwide. Although malicious activity was seen in the past, the spike and sudden decline observed later in February 2025 were notable, and offending IP addresses were investigated.
AS198953, belonging to Proton66 OOO, consists of five net blocks, which are currently listed on blocklists such as Spamhaus due to malicious activity. Net blocks 45.135.232.0/24 and 45.140.17.0/24 were particularly active in terms of mass scanning and brute force attempts. Several of the offending IP addresses were not previously seen to be involved in malicious activity or were inactive for over two years. For instance, the last activities reported in AbuseIPDB for the IP addresses 45.134.26.8 and 45.135.232.24 were noted in November and July 2021, respectively.
