Hvězdička u CVE znamená, že jsem to číslo vytáhl z širšího textu článku.
Neukazuju u něj proto KEV, EPSS ani CVSS, a to preventivně, protože článek se na něj mohl
jen odkazovat, třeba jako na starší kauzu.
For an experiment, I created a script [1] that parses and send the TTY logs collected from actors or bots activity that run various commands after they successfully login the DShield sensor. Those TTY logs are sent daily at the end of each day to the DShield SIEM [2] to be correlated with all the data. The following ES|QL query provides a summary of all contab commands matching a TTYLog hash performed by different actors while logged in the sensor over a 90 day period. TTYLogs Correlation FROM…
Of Elastic's 2100+ prebuilt detection rules, 385 are tagged Profile: Recommended and 296 are tagged Aggressive. The rest (62% of the list) are deliberately left untagged. Prebuilt rule now carries tags like Noise: Low, Performance: Fast, and Profile: Recommended, recalculated every month from real fleet telemetry rather than fixed once and left alone. This post covers how the scoring actually works and how to use the tags to decide what to enable first. Elastic SIEM rule metadata has two jobs…
Sometimes I have to smile, or my interest is triggered, when I review new User Agent Strings in the honeypot logs. Like when I see an "authorized" scan: Or when I'm owned for the umpteenth time: I regularly see URLs or email addresses for when you want to know more, or get in touch, with the persons behind a scanner: (around the end of this list, you'll see the Belarus email address we wrote about recently) Many variants of masscan: Even a KGB variant. As you can guess, "scan" is a popular word…
Overview Rapid7 tracked a set of Linux samples that blend into the software and device conventions of the telecom environments they target. The set spans a newly observed BPFDoor variant, a BPF Rekoobe build seen against South Korean targets, a dropper, and six builds of a Linux implant we track as AVERAT, deployed against Taiwanese appliances. Additionally, we provide source code details of the Rapid7 BPFDoor controller introduced in our April 2026 blog, Stealthy BPFDoor Variants are a Needle…

Microsoft says cyberattackers are currently benefiting from artificial intelligence faster than defenders, allowing threat actors to speed up vulnerability discovery, malware development, and post-compromise activity while security teams struggle to keep pace. [...]
We found 70 websites that impersonate legitimate crypto projects that invite visitors to vote on the date of an upcoming rewards distribution. The pages copy the look of the real sites closely, and on most of them the offer is small and believable: Cast a vote, and as an active voter you get a 1.25x boost when the rewards are paid out. However, the vote is fake and clicking the Vote now button opens a wallet connection prompt. It’s the first step toward requests that could trick visitors into…
Every year, the Microsoft Digital Defense Report gives us an opportunity to step back from individual threats and look broadly at what Microsoft’s security and threat intelligence teams are seeing. Today, we released the 2026 Report, which reflects a security environment that continues to grow more interconnected. We see that across the report. Threat activity can span infrastructure, identities, applications, cloud environments, and software supply chains. AI systems and agents increasingly…
According to this year’s Microsoft Digital Defense Report, government agencies and services were the sector most impacted by cyber threats in 2026, accounting for 27% of observed activity, up from 17% in 2025. Governments are also the most frequently targeted sectors for nation-state activity. They are attractive targets because they hold sensitive information, operate essential services, and sit at the center of networks of agencies, contractors, technology providers, and critical…

Two separate investigations have raised concerns about betting site DraftKings’ marketing to target problem gamblers, including its use of AI. On September 19, the New York Times reported that the company’s machine learning model targeted people who were more likely to respond to betting promotions by gambling and losing more money. The model crunched data on each customer, including how often they bet, how much they lost, and what their daily account balances were. According to the report, it…

Written by: Robin Grunewald, Supriya Mazumdar, Kelli Vanderlee Introduction Google Threat Intelligence Group (GTIG) examines vulnerability disclosure and exploitation statistics to evaluate the impact of artificial intelligence (AI) on the vulnerability threat landscape. We found that AI is measurably changing not just the pace of vulnerability discovery and exploitation, but also the types and typical risk profiles of vulnerabilities that are being discovered. Key findings: Vulnerability…
A study testing 21 cars from 19 brands and 30 companion apps found connections to advertising and tracking companies, and evidence that some apps shared sensitive personal data. Modern cars can unlock remotely, route around traffic, stream entertainment, summon roadside help, and cool or heat the cabin before you get in. But those conveniences come with a privacy cost that drivers may struggle to see and are unable to refuse. We’ve covered cars and privacy a few times before, especially after…
Cisco Talos uncovered a cluster of activity we track as UAT-11587 targeting government and policy organizations across Asia, including in Taiwan, India, the Philippines, and Cambodia, to deliver a previously undocumented backdoor referred to as “Antino” in developer artifacts. Talos first observed UAT-11587 activity in September 2025. By July 2026, Talos had identified at least 16 affected or targeted institutional environments across eight Asian countries. Antino is a Rust-compiled Windows…
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).

Starting yesterday, our sensors picked up a small number of scans for "wordfence-waf.php". This particular script is used by Wordfence, a solution to protect WordPress sites. During the Wordfence install, the wordpress-waf.php file will be created in the site's root directory [1]. The requests themselves are unremarkable, not including any headers like User-Agent. Just the bare minimum "Host" header, which is the IP address of the targeted site. The file does not include any secrets or…
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,…
A reminder for anyone who thinks their AI chats are private: A human may see what they upload. A report from 404 Media this week describes contractors reviewing Copilot users’ photos, editing requests, and the images Copilot produces. Some of what they see is disturbing. The third-party companies hired to conduct these reviews present their workers with an original photo and a user’s request for an edit. They are also shown two potential AI edits and asked to judge each on technical merit.…

On 24 September 2026, a malicious cyber actor (MCA) used 149.104.78.141 to attempt zero-day exploitation against a Citrix NetScaler Gateway. At the time, there were no CVE-specific detections for the attack due to it occurring pre-disclosure. However, GreyNoise still detected and labeled the activity as fundamentally malicious within seconds due to behavioral detections.
In this article Attack overviewTechnical analysisMitigation and protection guidanceReferencesLearn More Microsoft Security Research has identified malicious cloud activity associated with JADEPUFFER, a threat actor discovered by Sysdig in July 2026 and reported to be the first documented agentic ransomware operation. Our investigation found an extensive Azure-focused resource destruction activity using compromised service principals and cloud credential collection that could be used to…
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…
Thanks to Malwarebytes research engineer Stefan Dasic for his help with this article. A name like ShipmentsFree suggests a way to save on shipping. The service does offer shipping rebates, but its Better Business Bureau (BBB) complaint record shows that some customers did not realize they had also signed up for recurring charges. We found a number of very similar websites (which triggered our spidey senses), so we investigated. Related shipping-themed domains use ShipmentsFree or ShipmentFree…
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…

Threat actors exploited Samsung MagicINFO to install AnyDesk, disable Defender, and compile a Monero miner directly on a victim endpoint. Learn the detection signals.
Business Email Compromise (BEC) operates on a familiar playbook. Threat actors breach a mailbox, silently monitor operations, map approval chains, and ultimately exploit that access to divert funds or exfiltrate sensitive assets.This dynamic is central to our analysis as we kick off a series around Rapid7's collaborative research with Zimbra; upcoming installments will explore technical details and broader findings based within the Zimbra Collaboration Suite. Our investigation disrupted the…
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…
Yesterday, we received a phishing email with an interesting link. At first sight, it looks like garbage, but every piece of it has been carefully crafted to confuse basic security controls. Here is the defanged link: hxxps://YKZjqa7A@gynd--[.]koncar-hr[.]com/handlers@isc.sans.edu Let's break it down... The first trick is the old "userinfo" field. According to RFC 3986[1], everything between the scheme and an "@" inside the authority is treated as credentials ("user:password@host"). Browsers…
