У вересні 2026 року фахівцями CERT-UA виявлено майже 50 скомпрометованих вебсайтів, до сторінок яких зловмисниками додано шкідливий JavaScript-код. Під час відвідування такого сайту користувачеві демонструвалася підроблена сторінка перевірки Cloudflare, яка під приводом підтвердження того, що відвідувач є людиною, пропонувала виконати команду. Виконання команди призводило до завантаження та встановлення MSI-пакета з віддаленого сервера (техніка ClickFix).

Apple announced its first foldable iPhone on September 9, and scammers were ready to ‘deliver’ one before anyone could buy it. Most of what we found around the launch of the iPhone Duo and iPhone 18 Pro was familiar fraud. But one fake preorder page was different. The fake Apple-style page offers a $500 voucher and a ticking preorder deadline. Behind its Apple-style design and $500 voucher, the page uses the leaked DarkSword exploit chain to try to break into vulnerable iPhones. If it succeeds,…

Multiple sources reported malicious activity linked to JADEPUFFER (Storm-3168), an agentic ransomware operation, during June 2026. This attacker has been observed leveraging exposed secrets and exploiting vulnerabilities in Internet-facing software for initial access to cloud ...
We discovered an undocumented remote-access Trojan (RAT) called Kothamine Agent. It supports more than 30 commands and it gives attackers control of an infected Windows computer: they can run commands, read and change files, and add new capabilities. Some versions can also steal browser data and record through the camera and microphone. We found Kothamine linked to malicious npm packages, which could put users and developers who install those packages at risk. In recent versions, the malware…
A domain that has long appeared in software documentation, code examples, and developer test material is now being used to push a ClickFix attack against Windows users. A placeholder domain stands in for a website in an example. The best-known is probably example.com. Another, third-party[.]com, has often been used in documentation to represent an external website, API, or service. However, there is a very important difference between the two: example.com is reserved for documentation, while…
Introduction My previous post on Macfinger ClickFix was two days ago, and this campaign remains active. The more I look into the malware delivered by this campaign, the more I believe it is not a variant of Atomic macOS (AMOS) Stealer as originally reported. There are too many differences between what I've documented with recent AMOS Stealer activity and what I'm now seeing with this malware. The data collection and method of exfiltration is different between these two malware families. The…
A new botnet malware called Carbonato is targeting insecure hosts running Docker daemons to install the Hermes Agent AI framework and take control. [...]
Threat actors exploited Samsung MagicINFO to install AnyDesk, disable Defender, and compile a Monero miner directly on a victim endpoint. Learn the detection signals.
MacSync is a relatively young, rapidly evolving family of crypto/info stealers. First advertised on the dark web in 2025 as Mac.c, the stealer was later renamed to MacSync by its creators. The initial versions were implemented as AppleScripts and closely resembled the AMOS stealer family, but over time, MacSync developed distinctive features of its own, including a backdoor module. In this report, we discuss a new infection chain that differs significantly from previous variants. We first…
The "third-party.com" domain, commonly used as a placeholder in developer documentation and code examples, is serving a fake Cloudflare verification page that attempts to trick Windows users into executing PowerShell commands. [...]

Group-IB uncovers RemControl, a new Android banking trojan targeting European, Middle Eastern and Canadian banks, whose criminal infrastructure was unknowingly built by AI.
Introduction I've found several legitimate websites with injected script for a campaign using the ClickFix social engineering technique. This particular ClickFix campaign was documented earlier this month on the Ransom-ISAC Blog, but it doesn't appear to have a nickname yet. Since this campaign is targeting macOS environments through a fingerprinting process, I'm calling it the "Macfinger ClickFix" campaign. No, this is not related to the MacFinger utility from decades ago. Instead, think of…
DarkMe, an APT-linked VB6 RAT known for using zero day exploits, turned up in two Huntress incidents stripped down to a plain .pif infostealer malware.
A new Windows malware named ClosedQuorum uses Google Gemini, DeepSeek, Qwen, and Mistral AI models to autonomously determine the actions to take during post-compromise stages of an attack. [...]
Aikido found Graphalgo-linked Go malware in Terraform providers and Go Modules, using targeted triggers, Slack, and blockchain C2. Category: Vulnerabilities & Threats
CLOSEDQUORUM, a malware binary discovered through Cisco Talos’ CAIRN project, exhibits fully autonomous command and control (C2). While we do not have confirmation of in-the-wild deployment, artifacts from the binary were used to connect the developer to postings on criminal forums related to carding, dating back to 2025. This malware is a useful reference example of how attackers can collapse the decision space of a particular attack phase into a constrained set of choices, allowing AI models…
A cairn is a marker left behind on a trail, a deliberately placed stack of stones that helps hikers find their way when the path is unclear. Attackers building AI-integrated malware unintentionally (and inevitably) leave behind markers of their own: prompt templates, provider endpoints, API keys, jailbreak terms, and other artifacts embedded throughout their tooling. When we consider these strings as cognitive artifacts, or vestiges left behind from AI integration, we can enable a new, metadata…
For the latest discoveries in cyber research for the week of 21st Setpember, please download our Threat Intelligence Bulletin. TOP ATTACKS AND BREACHES Japan’s Digital Agency, which operates the Government Solution Service used by multiple ministries, has confirmed a data breach after attackers exploited a vulnerability in a VPN appliance.

On September 9, 2026, Volexity published a blog post detailing the simultaneous use of multiple chained zero-day exploits in Google Chrome (CVE-2026-85046, CVE-2026-87491) and Microsoft Windows (CVE-2026-85880) by two different Chinese advanced persistent threat (APT) actors. Shortly after that blog post was published, Volexity discovered additional campaigns—this time from a third Chinese threat actor, tracked by Volexity under the alias UTA0565—that used the same chained exploits on September…
Microsoft Security Research published an interesting blog post "TerminalFix campaign deploys a reverse tunnel through multistage intrusion" about a malware campaign. The aspect that I want to take a closer look at, is the fact that the threat actors used PNG files with steganography. I reached out to the researchers and they kindly shared the IOCs for the PNG files with me. The first image is a small PNG file (f5f1eb6d43dd61d5b069c250e5c666384f7417d0c95014773bf9edf8ff13bebe). Analysis with…
An ongoing npm malware campaign involving the 'indexed-btree' package shows how threat actors bypass supply chain defenses by hiding malicious code in a package's normal runtime behavior rather than in installation scripts. [...]
Executive Summary Following disclosure of the TraderTraitor attack against LayerZero in April 2026, SentinelOne identified an additional victim with the same macOS backdoors. Our analysis explores the mechanics of these backdoors and the expanded targeting against a victim in the IT services sector with no relationship to cryptocurrency trading. We also identified more weaponized GitHub repositories from the social engineering schemes used to target job seekers in these campaigns. This report…
Researchers at Zimperium’s zLabs have analyzed an Android Trojan that uses an automated, multi-stage infection process. What’s new is that RatHat gives a live AI assistant the keys to the accessibility tree of the infected device and uses it to determine where to tap or scroll, rather than following a hardcoded script. The variable attack path makes it harder for signature- and rule-based mobile security tools to detect this Trojan. It also abuses Android Debug Bridge (ADB), a legitimate tool…
An ongoing malware campaign uses SEO-optimized GitHub repositories to impersonate well-known software firms to push a previously undocumented information stealer called Rapuncel. [...]

Brevo confirmed that attackers stole a Cloudflare API key and used it to inject malicious ClickFix scripts into its websites and JavaScript files embedded on customer sites to distribute malware. [...]
AI has already made fundamental changes to the operating environment for cybersecurity. Cyberattackers are testing more paths, adapting their techniques, and moving across digital environments with greater speed and persistence. The weaknesses they exploit remain familiar: excessive permissions, unprotected authentication flows, unpatched systems, exposed execution paths, and gaps between controls. What has changed is how quickly these weaknesses can combine into attack paths that cross…
Questo CSIRT ha recentemente registrato, nel contesto nazionale, un aumento significativo di sfruttamenti attivi della CVE-2026-48907 – già sanata dal vendor e trattata nell’ambito dell’AL02/260615/CSIRT-ITA – ai danni di server web esposti. Tale vulnerabilità interessa il plugin Joomla Content Editor (JCE), estensione per il noto Content Management System (CMS) Joomla!.
At the end of August, a malspam message was caught in the quarantine of a mail gateway operated by one of my customers. The message was not especially remarkable – it asked the recipient to review some attached requirements and provide a price quotation for a fiber optic system and appeared to impersonate an employee of a legitimate company. The receiving gateway quarantined the message because it detected malicious content in the attachment, though even if it didn’t, the e-mail would not have…
Introduction Torrent trackers have long been abused for distributing malicious software, disguised as popular films, games, and other content. Our previous research has shown that cybercriminals repeatedly turn torrents as an initial infection vector, using trojanized cracks and installers to reach a large number of users. Installation guides for pirated software routinely instruct users to disable their antivirus, conditioning them to ignore potential threats they are inviting onto their…
