Cybersecurity researchers have flagged a Ukrainian IP network for engaging in massive brute-force and password spraying campaigns targeting SSL VPN and RDP devices between June and July 2025. The activity originated from a Ukraine-based autonomous system FDN3 ( AS211736 ), per French cybersecurity company Intrinsec. "We believe with a high level of confidence that FDN3 is part of a wider abusive infrastructure composed of two other Ukrainian networks, VAIZ-AS ( AS61432 ) and ERISHENNYA-ASN ( AS210950 ), and a Seychelles-based autonomous system named TK-NET ( AS210848 )," according to a report published last week. "Those were all allocated in August 2021 and often exchange IPv4 prefixes with one another to evade blocklisting and continue hosting abusive activities." AS61432 currently announces a single prefix 185.156.72[.]0/24, while AS210950 has announced two prefixes 45.143.201[.]0/24 and 185.193.89[.]0/24. The two autonomous systems were allocated in May an...

The threat actor known as Silver Fox has been attributed to abuse of a previously unknown vulnerable driver associated with WatchDog Anti-malware as part of a Bring Your Own Vulnerable Driver ( BYOVD ) attack aimed at disarming security solutions installed on compromised hosts. The vulnerable driver in question is "amsdk.sys" (version 1.0.600), a 64-bit, validly signed Windows kernel device driver that's assessed to be built upon Zemana Anti-Malware SDK. "This driver, built on the Zemana Anti-Malware SDK, was Microsoft-signed, not listed in the Microsoft Vulnerable Driver Blocklist , and not detected by community projects like LOLDrivers," Check Point said in an analysis. The attack is characterized by a dual-driver strategy, where a known vulnerable Zemana driver ("zam.exe") is used for Windows 7 machines, and the undetected WatchDog driver for systems that run on Windows 10 or 11. The WatchDog Anti-malware driver has been found to contain mu...

Cybersecurity researchers have discovered a malicious npm package that comes with stealthy features to inject malicious code into desktop apps for cryptocurrency wallets like Atomic and Exodus on Windows systems. The package, named nodejs-smtp , impersonates the legitimate email library nodemailer with an identical tagline, page styling, and README descriptions, attracting a total of 347 downloads since it was uploaded to the npm registry in April 2025 by a user named "nikotimon." It's currently no longer available. "On import, the package uses Electron tooling to unpack Atomic Wallet's app.asar, replace a vendor bundle with a malicious payload, repackage the application, and remove traces by deleting its working directory," Socket researcher Kirill Boychenko said . The main objective is to overwrite the recipient address with hard-coded wallets controlled by the threat actor, redirecting Bitcoin (BTC), Ethereum (ETH), Tether (USDT and TRX USDT), XRP...

Cybersecurity researchers are calling attention to a new shift in the Android malware landscape where dropper apps, which are typically used to deliver banking trojans, to also distribute simpler malware such as SMS stealers and basic spyware. These campaigns are propagated via dropper apps masquerading as government or banking apps in India and other parts of Asia, ThreatFabric said in a report last week. The Dutch mobile security firm said the change is driven by recent security protections that Google has piloted in select markets like Singapore, Thailand, Brazil, and India to block sideloading of potentially suspicious apps requesting dangerous permissions like SMS messages and accessibility services , a heavily abused setting to carry out malicious actions on Android devices.  "Google Play Protect's defences, particularly the targeted Pilot Program, are increasingly effective at stopping risky apps before they run," the company said. "Second, actors want t...

Cybersecurity today is less about single attacks and more about chains of small weaknesses that connect into big risks. One overlooked update, one misused account, or one hidden tool in the wrong hands can be enough to open the door. The news this week shows how attackers are mixing methods—combining stolen access, unpatched software, and clever tricks to move from small entry points to large consequences.  For defenders, the lesson is clear: the real danger often comes not from one major flaw, but from how different small flaws interact together. ⚡ Threat of the Week WhatsApp Patches Actively Exploited Flaw — WhatsApp addressed a security vulnerability in its messaging apps for Apple iOS and macOS that it said may have been exploited in the wild in conjunction with a recently disclosed Apple flaw in targeted zero-day attacks. The vulnerability, CVE-2025-55177 relates to a case of insufficient authorization of linked device synchronization messages. The Meta-owned company ...

As enterprises continue to shift their operations to the browser, security teams face a growing set of cyber challenges. In fact, over 80% of security incidents now originate from web applications accessed via Chrome, Edge, Firefox, and other browsers. One particularly fast-evolving adversary, Scattered Spider, has made it their mission to wreak havoc on enterprises by specifically targeting sensitive data on these browsers. Scattered Spider, also referred to as UNC3944, Octo Tempest, or Muddled Libra, has matured over the past two years through precision targeting of human identity and browser environments. This shift differentiates them from other notorious cybergangs like Lazarus Group, Fancy Bear, and REvil. If sensitive information such as your calendar, credentials, or security tokens is alive and well in browser tabs, Scattered Spider is able to acquire them.  In this article, you'll learn details about Scattered Spider's attack methods and how you can stop them in their ...

Cybersecurity researchers have discovered a new phishing campaign undertaken by the North Korea-linked hacking group called ScarCruft (aka APT37) to deliver a malware known as RokRAT. The activity has been codenamed Operation HanKook Phantom by Seqrite Labs, stating the attacks appear to target individuals associated with the National Intelligence Research Association, including academic figures, former government officials, and researchers. "The attackers likely aim to steal sensitive information, establish persistence, or conduct espionage," security researcher Dixit Panchal said in a report published last week. The starting point of the attack chain is a spear-phishing email containing a lure for "National Intelligence Research Society Newsletter—Issue 52," a periodic newsletter issued by a South Korean research group focused on national intelligence, labour relations, security, and energy issues. The digital missive contains a ZIP archive attachment that...

Cybersecurity researchers have called attention to a cyber attack in which unknown threat actors deployed an open-source endpoint monitoring and digital forensic tool called Velociraptor , illustrating ongoing abuse of legitimate software for malicious purposes. "In this incident, the threat actor used the tool to download and execute Visual Studio Code with the likely intention of creating a tunnel to an attacker-controlled command-and-control (C2) server," the Sophos Counter Threat Unit Research Team said in a report published this week.  While threat actors are known to adopt living-off-the-land (LotL) techniques or take advantage of legitimate remote monitoring and management (RMM) tools in their attacks, the use of Velociraptor signals a tactical evolution, where incident response programs are being used to obtain a foothold and minimize the need for having to deploy their own malware.  Further analysis of the incident has revealed that the attackers used the Wind...

Picture this: Your team rolls out some new code, thinking everything's fine. But hidden in there is a tiny flaw that explodes into a huge problem once it hits the cloud. Next thing you know, hackers are in, and your company is dealing with a mess that costs millions. Scary, right? In 2025, the average data breach hits businesses with a whopping $4.44 million bill globally. And guess what? A big chunk of these headaches comes from app security slip-ups, like web attacks that snag credentials and wreak havoc. If you're in dev, ops, or security, you've probably felt that stress—endless alerts, teams arguing over who's to blame, and fixes that take forever. But hey, it doesn't have to be this way. What if you could spot those risks early, from the moment code is written all the way to when it's running in the cloud? That's the magic of code-to-cloud visibility, and it's changing how smart teams handle app security. Our upcoming webinar, "Code-to-Clou...

Amazon on Friday said it flagged and disrupted what it described as an opportunistic watering hole campaign orchestrated by the Russia-linked APT29 actors as part of their intelligence gathering efforts. The campaign used "compromised websites to redirect visitors to malicious infrastructure designed to trick users into authorizing attacker-controlled devices through Microsoft's device code authentication flow," Amazon's Chief Information Security Officer CJ Moses said . APT29, also tracked as BlueBravo, Cloaked Ursa, CozyLarch, Cozy Bear, Earth Koshchei, ICECAP, Midnight Blizzard, and The Dukes, is the name assigned to a state-sponsored hacking group with ties to Russia's Foreign Intelligence Service (SVR). In recent months, the prolific threat actor has been linked to attacks leveraging malicious Remote Desktop Protocol (RDP) configuration files to target Ukrainian entities and exfiltrate sensitive data. Since the start of the year, the adversarial collec...
