The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Wednesday added a critical security flaw impacting Adobe Experience Manager to its Known Exploited Vulnerabilities ( KEV ) catalog, based on evidence of active exploitation. The vulnerability in question is CVE-2025-54253 (CVSS score: 10.0), a maximum-severity misconfiguration bug that could result in arbitrary code execution. According to Adobe, the shortcoming impacts Adobe Experience Manager (AEM) Forms on JEE versions 6.5.23.0 and earlier. It was addressed in version 6.5.0-0108 released early August 2025, alongside CVE-2025-54254 (CVSS score: 8.6). Details of the two vulnerabilities were disclosed by Searchlight Cyber researchers Adam Kues and Shubham Shah in July 2025, describing CVE-2025-54253 as an "authentication bypass to [remote code execution] chain via Struts2 devmode" and CVE-2025-54254 as an XML external entity (XXE) injection within AEM Forms web services. The flaw results from the dan...

A threat actor with ties to China has been attributed to a five-month-long intrusion targeting a Russian IT service provider, marking the hacking group's expansion to the country beyond Southeast Asia and South America. The activity, which took place from January to May 2025, has been attributed by Broadcom-owned Symantec to a threat actor it tracks as Jewelbug , which it said overlaps with clusters known as CL-STA-0049 (Palo Alto Networks Unit 42), Earth Alux (Trend Micro), and REF7707 (Elastic Security Labs). The findings suggest Russia is not off-limits for Chinese cyber espionage operations despite increased "military, economic, and diplomatic" relations between Moscow and Beijing over the years. "Attackers had access to code repositories and software build systems that they could potentially leverage to carry out supply chain attacks targeting the company's customers in Russia," the Symantec Threat Hunter Team said in a report shared with The ...

U.S. cybersecurity company F5 on Wednesday disclosed that unidentified threat actors broke into its systems and stole files containing some of BIG-IP's source code and information related to undisclosed vulnerabilities in the product. It attributed the activity to a "highly sophisticated nation-state threat actor," adding the adversary maintained long-term, persistent access to its network. The company said it learned of the breach on August 9, 2025, per a Form 8-K filing with the U.S. Securities and Exchange Commission (SEC). F5 said it delayed the public disclosure at the request of the U.S. Department of Justice (DoJ). "We have taken extensive actions to contain the threat actor," it noted . "Since beginning these activities, we have not seen any new unauthorized activity, and we believe our containment efforts have been successful." F5 did not say for how long the threat actors had access to its BIG-IP product development environment, but em...

New research has uncovered that publishers of over 100 Visual Studio Code (VS Code) extensions leaked access tokens that could be exploited by bad actors to update the extensions, posing a critical software supply chain risk. "A leaked VS Code Marketplace or Open VSX PAT [personal access token] allows an attacker to directly distribute a malicious extension update across the entire install base," Wiz security researcher Rami McCarthy said in a report shared with The Hacker News. "An attacker who discovered this issue would have been able to directly distribute malware to the cumulative 150,000 install base." The cloud security firm noted in many cases publishers failed to account for the fact that VS Code extensions, while distributed as .vsix files, can be unzipped and inspected, exposing hard-coded secrets embedded into them. In all, Wiz said it found over 550 validated secrets, distributed across more than 500 extensions from hundreds of distinct publishers....

TLDR Even if you take nothing else away from this piece, if your organization is evaluating passkey deployments, it is insecure to deploy synced passkeys. Synced passkeys inherit the risk of the cloud accounts and recovery processes that protect them, which creates material enterprise exposure. Adversary-in-the-middle (AiTM) kits can force authentication fallbacks that circumvent strong authentication all together Malicious or compromised browser extensions can hijack WebAuthn requests, manipulate passkey registration or sign-in, and drive autofill to leak credentials and one-time codes. Device-bound passkeys in hardware security keys offer higher assurance and better administrative control than synced passkeys, and should be mandatory for enterprise access use cases Synced Passkey Risks Synced passkey vulnerabilities Passkeys are credentials stored in an authenticator. Some are device-bound, others are synced across devices through consumer cloud services like iCloud and Go...

Microsoft on Tuesday released fixes for a whopping 183 security flaws spanning its products, including three vulnerabilities that have come under active exploitation in the wild, as the tech giant officially ended support for its Windows 10 operating system unless the PCs are enrolled in the Extended Security Updates ( ESU ) program. Of the 183 vulnerabilities, eight of them are non-Microsoft issued CVEs. As many as 165 flaws have been rated as Important in severity, followed by 17 as Critical and one as Moderate. The vast majority of them relate to elevation of privilege vulnerabilities (84), with remote code execution (33), information disclosure (28), spoofing (14), denial-of-service (11), and security feature bypass (11) issues accounting for the rest. The updates are in addition to the 25 vulnerabilities Microsoft addressed in its Chromium-based Edge browser since the release of September 2025's Patch Tuesday update . The two Windows zero-days that have come under activ...

Cybersecurity researchers have disclosed two critical security flaws impacting Red Lion Sixne t remote terminal unit (RTU) products that, if successfully exploited, could result in code execution with the highest privileges. The shortcomings, tracked as CVE-2023-40151 and CVE-2023-42770 , are both rated 10.0 on the CVSS scoring system. "The vulnerabilities affect Red Lion SixTRAK and VersaTRAK RTUs, and allow an unauthenticated attacker to execute commands with root privileges," Claroty Team 82 researchers said in a report published Tuesday. Red Lion's Sixnet RTUs provide advanced automation, control, and data acquisition capabilities in industrial automation and control systems, primarily across energy, water, and wastewater treatment, transportation, utilities, and manufacturing sectors. These industrial devices are configured using a Windows utility called Sixnet IO Tool Kit, with a proprietary Sixnet "Universal" protocol used to interface and enable ...

Cybersecurity researchers have disclosed that a critical security flaw impacting ICTBroadcast, an autodialer software from ICT Innovations, has come under active exploitation in the wild. The vulnerability, assigned the CVE identifier CVE-2025-2611 (CVSS score: 9.3), relates to improper input validation that can result in unauthenticated remote code execution due to the fact that the call center application unsafely passes session cookie data to shell processing. This, in turn, allows an attacker to inject shell commands into a session cookie that can get executed in the vulnerable server. The security flaw affects ICTBroadcast versions 7.4 and below. "Attackers are leveraging the unauthenticated command injection in ICTBroadcast via the BROADCAST cookie to gain remote code execution," VulnCheck's Jacob Baines said in a Tuesday alert. "Approximately 200 online instances are exposed." The cybersecurity firm said that it detected in-the-wild exploitation o...

SAP has rolled out security fixes for 13 new security issues , including additional hardening for a maximum-severity bug in SAP NetWeaver AS Java that could result in arbitrary command execution. The vulnerability, tracked as CVE-2025-42944, carries a CVSS score of 10.0. It has been described as a case of insecure deserialization. "Due to a deserialization vulnerability in SAP NetWeaver, an unauthenticated attacker could exploit the system through the RMI-P4 module by submitting a malicious payload to an open port," according to a description of the flag in CVE.org. "The deserialization of such untrusted Java objects could lead to arbitrary OS command execution, posing a high impact to the application's confidentiality, integrity, and availability." While the vulnerability was first addressed by SAP last month, security company Onapsis said the latest fix provides extra safeguards to secure against the risk posed by deserialization. "The additional...

Threat actors with ties to China have been attributed to a novel campaign that compromised an ArcGIS system and turned it into a backdoor for more than a year. The activity, per ReliaQuest, is the handiwork of a Chinese state-sponsored hacking group called Flax Typhoon , which is also tracked as Ethereal Panda and RedJuliett. According to the U.S. government, it's assessed to be a publicly-traded, Beijing-based company known as Integrity Technology Group. "The group cleverly modified a geo-mapping application's Java server object extension (SOE) into a functioning web shell," the cybersecurity company said in a report shared with The Hacker News. "By gating access with a hardcoded key for exclusive control and embedding it in system backups, they achieved deep, long-term persistence that could survive a full system recovery." Flax Typhoon is known for living up to the "stealth" in its tradecraft by extensively incorporating living-off-the-l...

Every October brings a familiar rhythm - pumpkin-spice everything in stores and cafés, alongside a wave of reminders, webinars, and checklists in my inbox. Halloween may be just around the corner, yet for those of us in cybersecurity, Security Awareness Month is the true seasonal milestone. Make no mistake, as a security professional, I love this month. Launched by CISA and the National Cybersecurity Alliance back in 2004, it's designed to make security a shared responsibility. It helps regular citizens, businesses, and public agencies build safer digital habits. And it works. It draws attention to risk in its many forms, sparks conversations that otherwise might not happen, and helps employees recognize their personal stake in and influence over the organization's security.  Security Awareness Month initiatives boost confidence, sharpen instincts, and keep security at the front of everyone's mind... until the winter holiday season decorations start to go up, that is. After th...

Chipmaker AMD has released fixes to address a security flaw dubbed RMPocalypse that could be exploited to undermine confidential computing guarantees provided by Secure Encrypted Virtualization with Secure Nested Paging ( SEV-SNP ). The attack , per ETH Zürich researchers Benedict Schlüter and Shweta Shinde, exploits AMD's incomplete protections that make it possible to perform a single memory write to the Reverse Map Paging (RMP) table, a data structure that's used to store security metadata for all DRAM pages in the system. "The Reverse Map Table (RMP) is a structure that resides in DRAM and maps system physical addresses (sPAs) to guest physical addresses (gPAs)," according to AMD's specification documentation . "There is only one RMP for the entire system, which is configured using x86 model-specific registers (MSRs)." "The RMP also contains various security attributes of each that are managed by the hypervisor through hardware-mediated and...

Android devices from Google and Samsung have been found vulnerable to a side-channel attack that could be exploited to covertly steal two-factor authentication (2FA) codes, Google Maps timelines, and other sensitive data without the users' knowledge pixel-by-pixel. The attack has been codenamed Pixnapping by a group of academics from the University of California (Berkeley), University of Washington, University of California (San Diego), and Carnegie Mellon University. Pixnapping, at its core, is a pixel-stealing framework aimed at Android devices in a manner that bypasses browser mitigations and even siphons data from non-browser apps like Google Authenticator by taking advantage of Android APIs and a hardware side-channel, allowing a malicious app to weaponize the technique to capture 2FA codes in under 30 seconds. "Our key observation is that Android APIs enable an attacker to create an analog to [Paul] Stone-style attacks outside of the browser," the researchers...

Before an attacker ever sends a payload, they've already done the work of understanding how your environment is built. They look at your login flows, your JavaScript files, your error messages, your API documentation, your GitHub repos. These are all clues that help them understand how your systems behave. AI is significantly accelerating reconnaissance and enabling attackers to map your environment with greater speed and precision. While the narrative often paints AI as running the show, we're not seeing AI take over offensive operations end to end. AI is not autonomously writing exploits, chaining attacks, and breaching systems without the human in the loop. What it is doing is speeding up the early and middle stages of the attacker workflow: gathering information, enriching it, and generating plausible paths to execution.  Think of it like AI-generated writing; AI can produce a draft quickly given the right parameters, but someone still needs to review, refine, and tune it f...

Cybersecurity researchers have identified several malicious packages across npm, Python, and Ruby ecosystems that leverage Discord as a command-and-control (C2) channel to transmit stolen data to actor-controlled webhooks. Webhooks on Discord are a way to post messages to channels in the platform without requiring a bot user or authentication, making them an attractive mechanism for attackers to exfiltrate data to a channel under their control. "Importantly, webhook URLs are effectively write-only," Socket researcher Olivia Brown said in an analysis. "They do not expose channel history, and defenders cannot read back prior posts just by knowing the URL." The software supply chain security company said it identified a number of packages that use Discord webhooks in various ways - mysql-dumpdiscord (npm), which siphons the contents of developer configuration files like config.json, .env, ayarlar.js, and ayarlar.json to a Discord webhook nodejs.discord (npm...

Cybersecurity researchers have shed light on a previously undocumented threat actor called TA585 that has been observed delivering an off-the-shelf malware called MonsterV2 via phishing campaigns. The Proofpoint Threat Research Team described the threat activity cluster as sophisticated, leveraging web injections and filtering checks as part of its attack chains. "TA585 is notable because it appears to own its entire attack chain with multiple delivery techniques," researchers Kyle Cucci, Tommy Madjar, and Selena Larson said . "Instead of leveraging other threat actors – like paying for distribution, buying access from initial access brokers, or using a third-party traffic delivery system – TA585 manages its own infrastructure, delivery, and malware installation." MonsterV2 is a remote access trojan (RAT), stealer, and loader, which Proofpoint first observed being advertised on criminal forums in February 2025. It's worth noting that MonsterV2 is also calle...

Every week, the cyber world reminds us that silence doesn't mean safety. Attacks often begin quietly — one unpatched flaw, one overlooked credential, one backup left unencrypted. By the time alarms sound, the damage is done. This week's edition looks at how attackers are changing the game — linking different flaws, working together across borders, and even turning trusted tools into weapons. From major software bugs to AI abuse and new phishing tricks, each story shows how fast the threat landscape is shifting and why security needs to move just as quickly. ⚡ Threat of the Week Dozens of Orgs Impacted by Exploitation of Oracle EBS Flaw — Dozens of organizations may have been impacted following the zero-day exploitation of a security flaw in Oracle's E-Business Suite (EBS) software since August 9, 2025, according to Google Threat Intelligence Group (GTIG) and Mandiant. The activity, which bears some hallmarks associated with the Cl0p ransomware crew, is assessed to have fashio...

For 2025: What security steps and monitoring should online retailers take now to prevent similar attacks while still using the third-party tools they need? As holiday shopping traffic increases, companies strengthen their servers and networks, but a critical weak spot remains unwatched: the browser environment where malicious code r...

Malware campaigns distributing the RondoDox botnet have expanded their targeting focus to exploit more than 50 vulnerabilities across over 30 vendors. The activity, described as akin to an "exploit shotgun" approach, has singled out a wide range of internet-exposed infrastructure, including routers, digital video recorders (DVRs), network video recorders (NVRs), CCTV systems, web servers, and various other network devices, according to Trend Micro. The cybersecurity company said it detected a RondoDox intrusion attempt on June 15, 2025, when the attackers exploited CVE-2023-1389 , a security flaw in TP-Link Archer routers that has come under active exploitation repeatedly since it was first disclosed in late 2022. RondoDox was first documented by Fortinet FortiGuard Labs back in July 2025, detailing attacks aimed at TBK digital video recorders (DVRs) and Four-Faith routers to enlist them in a botnet for carrying out distributed denial-of-service (DDoS) attacks agains...

Microsoft said it has revamped the Internet Explorer (IE) mode in its Edge browser after receiving "credible reports" in August 2025 that unknown threat actors were abusing the backward compatibility feature to gain unauthorized access to users' devices. "Threat actors were leveraging basic social engineering techniques alongside unpatched (0-day) exploits in Internet Explorer's JavaScript engine (Chakra) to gain access to victim devices," the Microsoft Browser Vulnerability Research team said in a report published last week. In the attack chain documented by the Windows maker, the threat actors have been found to trick unsuspecting users into visiting an seemingly legitimate website and then employ a flyout on the page to instruct them into reloading the page in IE mode. Once the page is reloaded, the attackers are said to have weaponized an unspecified exploit in the Chakra engine to obtain remote code execution. The infection sequence culminates w...
