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 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 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...

Click Studios, the developer of enterprise-focused password management solution Passwordstate, said it has released security updates to address an authentication bypass vulnerability in its software. The high-severity issue , which is yet to be assigned a CVE identifier, has been addressed in Passwordstate 9.9 (Build 9972), released August 28, 2025. The Australian company said it fixed a "potential Authentication Bypass when using a carefully crafted URL against the core Passwordstate Products' Emergency Access page." Also included in the latest version are improved protections to safeguard against potential clickjacking attacks aimed at its browser extension, should users end up visiting compromised sites. The safeguards are likely in response to findings from security researcher Marek Tóth, who, earlier this month, detailed a technique called Document Object Model (DOM)-based extension clickjacking that several password manager browser add-ons have been found vul...

Authorities from the Netherlands and the United States have announced the dismantling of an illicit marketplace called VerifTools that peddled fraudulent identity documents to cybercriminals across the world. To that end, two marketplace domains (verif[.]tools and veriftools[.]net) and one blog have been taken down, redirecting site visitors to a splash page stating the action was undertaken by the U.S. Federal Bureau of Investigation (FBI) pursuant to a warrant issued by a United States District Court. The servers were seized in Amsterdam. However, a Telegram message posted by operators on August 28, 2025, shows that they have already relaunched the service on the domain "veriftools[.]com." The domain was created on December 10, 2018, per DomainTools . It's currently not known who the administrators of the platform are. "The operators of VerifTools produced and sold counterfeit driver's licenses, passports, and other identification documents that could be u...

Google has revealed that the recent wave of attacks targeting Salesforce instances via Salesloft Drift is much broader in scope than previously thought, stating it impacts all integrations. "We now advise all Salesloft Drift customers to treat any and all authentication tokens stored in or connected to the Drift platform as potentially compromised," Google Threat Intelligence Group (GTIG) and Mandiant said in an updated advisory. The tech giant said the attackers also used stolen OAuth tokens to access email from a small number of Google Workspace email accounts on August 9, 2025, after compromising the OAuth tokens for the "Drift Email" integration. It's worth noting that this is not a compromise of Google Workspace or Alphabet itself. "The only accounts that were potentially accessed were those that had been specifically configured to integrate with Salesloft; the actor would not have been able to access any other accounts on a customer's Worksp...

Cybersecurity researchers have discovered a cybercrime campaign that's using malvertising tricks to direct victims to fraudulent sites to deliver a new information stealer called TamperedChef . "The objective is to lure victims into downloading and installing a trojanized PDF editor, which includes an information-stealing malware dubbed TamperedChef," Truesec researchers Mattias Wåhlén, Nicklas Keijser, and Oscar Lejerbäck Wolf said in a report published Wednesday. "The malware is designed to harvest sensitive data, including credentials and web cookies." At the heart of the campaign is the use of several bogus sites to promote an installer for a free PDF editor called AppSuite PDF Editor that, once installed and launched, displays to the user a prompt to agree to the software's terms of service and privacy policy. In the background, however, the setup program makes covert requests to an external server to drop the PDF editor program, while also setting...

The China-linked advanced persistent threat (APT) actor known as Salt Typhoon has continued its attacks targeting networks across the world, including organizations in the telecommunications, government, transportation, lodging, and military infrastructure sectors. "While these actors focus on large backbone routers of major telecommunications providers, as well as provider edge (PE) and customer edge (CE) routers, they also leverage compromised devices and trusted connections to pivot into other networks," according to a joint cybersecurity advisory published Wednesday. "These actors often modify routers to maintain persistent, long-term access to networks." The bulletin , courtesy of authorities from 13 countries, said the malicious activity has been linked to three Chinese entities, Sichuan Juxinhe Network Technology Co., Ltd., Beijing Huanyu Tianqiong Information Technology Co., Ltd., and Sichuan Zhixin Ruijie Network Technology Co., Ltd. These companies,...

Every day, businesses, teams, and project managers trust platforms like Trello, Asana, etc., to collaborate and manage tasks. But what happens when that trust is broken? According to a recent report by Statista, the average cost of a data breach worldwide was about $4.88 million. Also, in 2024, the private data of over 15 million Trello user profiles was shared on a popular hacker forum. Yet, most organizations and project managers still assume that their platform's built-in backups are enough until they are not. The next few paragraphs will expose some risks of relying on these platform tools alone and how to better protect yourself and your organization from data loss with cloud backup and recovery . Why are project management tools becoming a prime target for data loss? More than 95% of businesses today rely heavily on project management tools like Trello and Asana to organize tasks, collaborate with teams, and track project milestones. However, as project managers become mor...

The U.S. Department of the Treasury's Office of Foreign Assets Control (OFAC) announced a fresh round of sanctions against two individuals and two entities for their role in the North Korean remote information technology (IT) worker scheme to generate illicit revenue for the regime's weapons of mass destruction and ballistic missile programs. "The North Korean regime continues to target American businesses through fraud schemes involving its overseas IT workers, who steal data and demand ransom," said Under Secretary of the Treasury for Terrorism and Financial Intelligence John K. Hurley. "Under President Trump, Treasury is committed to protecting Americans from these schemes and holding the guilty accountable." The key players targeted include Vitaliy Sergeyevich Andreyev, Kim Ung Sun, Shenyang Geumpungri Network Technology Co., Ltd, and Korea Sinjin Trading Corporation. The latest effort expands the scope of sanctions imposed against Chinyong Informat...

The financially motivated threat actor known as Storm-0501 has been observed refining its tactics to conduct data exfiltration and extortion attacks targeting cloud environments. "Unlike traditional on-premises ransomware, where the threat actor typically deploys malware to encrypt critical files across endpoints within the compromised network and then negotiates for a decryption key, cloud-based ransomware introduces a fundamental shift," the Microsoft Threat Intelligence team said in a report shared with The Hacker News. "Leveraging cloud-native capabilities, Storm-0501 rapidly exfiltrates large volumes of data, destroys data and backups within the victim environment, and demands ransom -- all without relying on traditional malware deployment." Storm-0501 was first documented by Microsoft almost a year ago, detailing its hybrid cloud ransomware attacks targeting government, manufacturing, transportation, and law enforcement sectors in the U.S., with the thr...

Anthropic on Wednesday revealed that it disrupted a sophisticated operation that weaponized its artificial intelligence (AI)-powered chatbot Claude to conduct large-scale theft and extortion of personal data in July 2025. "The actor targeted at least 17 distinct organizations, including in healthcare, the emergency services, and government, and religious institutions," the company said . "Rather than encrypt the stolen information with traditional ransomware, the actor threatened to expose the data publicly in order to attempt to extort victims into paying ransoms that sometimes exceeded $500,000." "The actor employed Claude Code on Kali Linux as a comprehensive attack platform, embedding operational instructions in a CLAUDE.md file that provided persistent context for every interaction." The unknown threat actor is said to have used AI to an "unprecedented degree," using Claude Code, Anthropic's agentic coding tool, to automate variou...

A threat activity cluster known as ShadowSilk has been attributed to a fresh set of attacks targeting government entities within Central Asia and Asia-Pacific (APAC). According to Group-IB, nearly three dozen victims have been identified, with the intrusions mainly geared towards data exfiltration. The hacking group shares toolset and infrastructural overlaps with campaigns undertaken by threat actors dubbed YoroTrooper, SturgeonPhisher, and Silent Lynx. Victims of the group's campaigns span Uzbekistan, Kyrgyzstan, Myanmar, Tajikistan, Pakistan, and Turkmenistan, a majority of which are government organizations, and to a lesser extent, entities in the energy, manufacturing, retail, and transportation sectors. "The operation is run by a bilingual crew – Russian-speaking developers tied to legacy YoroTrooper code and Chinese-speaking operators spearheading intrusions, resulting in a nimble, multi-regional threat profile," researchers Nikita Rostovcev and Sergei Turner ...
