Cisco has confirmed that a Chinese threat actor known as Salt Typhoon gained access by likely abusing a known security flaw tracked as CVE-2018-0171 , and by obtaining legitimate victim login credentials as part of a targeted campaign aimed at major U.S. telecommunications companies. "The threat actor then demonstrated their ability to persist in target environments across equipment from multiple vendors for extended periods, maintaining access in one instance for over three years," Cisco Talos said , describing the hackers as highly sophisticated and well-funded. "The long timeline of this campaign suggests a high degree of coordination, planning, and patience — standard hallmarks of advanced persistent threat (APT) and state-sponsored actors." The networking equipment major said it found no evidence that other known security bugs have been weaponized by the hacking crew, contrary to a recent report from Recorded Future that revealed exploitation attempts inv...

A high-severity security flaw impacting the Craft content management system (CMS) has been added by the U.S. Cybersecurity and Infrastructure Security Agency (CISA) to its Known Exploited Vulnerabilities ( KEV ) catalog, based on evidence of active exploitation. The vulnerability in question is CVE-2025-23209 (CVSS score: 8.1), which impacts Craft CMS versions 4 and 5. It was addressed by the project maintainers in late December 2024 in versions 4.13.8 and 5.5.8. "Craft CMS contains a code injection vulnerability that allows for remote code execution as vulnerable versions have compromised user security keys," the agency said. The vulnerability affects the following version of the software - >= 5.0.0-RC1, < 5.5.5 >= 4.0.0-RC1, < 4.13.8 In an advisory released on GitHub, Craft CMS noted that all unpatched versions of Craft with a compromised security key are impacted by the security defect. "If you can't update to a patched version, then rota...

Freelance software developers are the target of an ongoing campaign that leverages job interview-themed lures to deliver cross-platform malware families known as BeaverTail and InvisibleFerret. The activity, linked to North Korea, has been codenamed DeceptiveDevelopment, which overlaps with clusters tracked under the names Contagious Interview (aka CL-STA-0240 ), DEV#POPPER, Famous Chollima, PurpleBravo, and Tenacious Pungsan. The campaign has been ongoing since at least late 2023. "DeceptiveDevelopment targets freelance software developers through spear-phishing on job-hunting and freelancing sites, aiming to steal cryptocurrency wallets and login information from browsers and password managers," cybersecurity company ESET said in a report shared with The Hacker News. In November 2024, ESET confirmed to The Hacker News the overlaps between DeceptiveDevelopment and Contagious Interview, classifying it as a new Lazarus Group activity that operates with an aim to conduc...

SaaS Adoption is Skyrocketing, Resilience Hasn't Kept Pace SaaS platforms have revolutionized how businesses operate. They simplify collaboration, accelerate deployment, and reduce the overhead of managing infrastructure. But with their rise comes a subtle, dangerous assumption: that the convenience of SaaS extends to resilience. It doesn't. These platforms weren't built with full-scale data protection in mind . Most follow a shared responsibility model — wherein the provider ensures uptime and application security, but the data inside is your responsibility. In a world of hybrid architectures, global teams, and relentless cyber threats, that responsibility is harder than ever to manage. Modern organizations are being stretched across: Hybrid and multi-cloud environments with decentralized data sprawl Complex integration layers between IaaS, SaaS, and legacy systems Expanding regulatory pressure with steeper penalties for noncompliance Escalating ransomware threats and inside...

PCI DSS 4.0 encourages the implementation of anti-phishing controls like DMARC! This highlights and reinforces the importance of preventative measures against email fraud, domain spoofing, and phishing in the financial space. While not a mandate or a requirement for PCI DSS compliance, DMARC and supporting email authentication technologies like SPF and DKIM play a pivotal role in protecting domain names against misuse.  Organizations can sign up for a DMARC analyzer trial to simplify their DMARC implementation, without the need for technical expertise. With more than 94% of organizations falling victim to phishing, this is the cue for businesses of all sizes to strengthen domain security and prevent the next big cyber attack. Many organizations turn to email authentication management solutions like PowerDMARC to simplify implementation, monitor authentication, and ensure continuous protection. On the flip side, it also presents a golden opportunity for MSPs to sell DMARC to th...

A previously unknown threat activity cluster targeted European organizations, particularly those in the healthcare sector, to deploy PlugX and its successor, ShadowPad, with the intrusions ultimately leading to deployment of a ransomware called NailaoLocker in some cases. The campaign, codenamed Green Nailao by Orange Cyberdefense CERT, involved the exploitation of a now-patched security flaw in Check Point network gateway security products ( CVE-2024-24919 , CVSS score: 7.5). The attacks were observed between June and October 2024. "The campaign relied on DLL search-order hijacking to deploy ShadowPad and PlugX – two implants often associated with China-nexus targeted intrusions," the company said in a technical report shared with The Hacker News. The initial access afforded by exploitation of vulnerable Check Point instances is said to have allowed the threat actors to retrieve user credentials and to connect to the VPN using a legitimate account. In the next stage,...

A malware campaign distributing the XLoader malware has been observed using the DLL side-loading technique by making use of a legitimate application associated with the Eclipse Foundation. "The legitimate application used in the attack, jarsigner, is a file created during the installation of the IDE package distributed by the Eclipse Foundation," the AhnLab SEcurity Intelligence Center (ASEC) said . "It is a tool for signing JAR (Java Archive) files." The South Korean cybersecurity firm said the malware is propagated in the form of a compressed ZIP archive that includes the legitimate executable as well as the DLLs that are sideloaded to launch the malware - Documents2012.exe, a renamed version of the legitimate jarsigner.exe binary, jli.dll, a DLL file that's modified by the threat actor to decrypt and inject concrt140e.dll, and concrt140e.dll, the XLoader payload The attack chain crosses over to the malicious phase when "Documents2012.exe...

For decades, Microsoft Exchange has been the backbone of business communications, powering emailing, scheduling and collaboration for organizations worldwide. Whether deployed on-premises or in hybrid environments, companies of all sizes rely on Exchange for seamless internal and external communication, often integrating it deeply with their workflows, compliance policies and security frameworks. However, Microsoft has officially announced that support for Exchange Server 2016 and Exchange Server 2019 will end on October 14, 2025. While this may seem like a distant concern, businesses and IT teams must start preparing now. The end of support means that Microsoft will no longer provide security patches, bug fixes or technical support, leaving organizations running on these versions exposed to security vulnerabilities, compliance risks and potential operational disruptions. So, what should businesses do now? In this article, we'll explore the impact of Microsoft's decision, the risks...

Citrix has released security updates for a high-severity security flaw impacting NetScaler Console (formerly NetScaler ADM) and NetScaler Agent that could lead to privilege escalation under certain conditions. The vulnerability, tracked as CVE-2024-12284 , has been given a CVSS v4 score of 8.8 out of a maximum of 10.0. It has been described as a case of improper privilege management that could result in authenticated privilege escalation if the NetScaler Console Agent is deployed and allows an attacker to execute post-compromise actions. "The issue arises due to inadequate privilege management and could be exploited by an authenticated malicious actor to execute commands without additional authorization," Netscaler noted . "However, only authenticated users with existing access to the NetScaler Console can exploit this vulnerability, thereby limiting the threat surface to only authenticated users." The shortcoming affects the below versions - NetScaler Cons...

No customer action is required. On the other hand, CVE-2025-24989 concerns a case of improper access control in Power Pages , a low-code platform for creating, hosting, and managing secure business websites, that an unauthorized attacker could exploit to elevate privileges over a network and bypass user registration control. Microsoft, which credited its own employee Raj Kumar for flagging the vul...

Multiple Russia-aligned threat actors have been observed targeting individuals of interest via the privacy-focused messaging app Signal to gain unauthorized access to their accounts. "The most novel and widely used technique underpinning Russian-aligned attempts to compromise Signal accounts is the abuse of the app's legitimate 'linked devices' feature that enables Signal to be used on multiple devices concurrently," the Google Threat Intelligence Group (GTIG) said in a report. In the attacks spotted by the tech giant's threat intelligence teams, the threat actors, including one it's tracking as UNC5792, have resorted to malicious QR codes that, when scanned, will link a victim's account to an actor-controlled Signal instance. As a result, future messages get delivered synchronously to both the victim and the threat actor in real-time, thereby granting threat actors a persistent way to eavesdrop on the victim's conversations. Google said UAC-...

A new variant of the Snake Keylogger malware is being used to actively target Windows users located in China, Turkey, Indonesia, Taiwan, and Spain. Fortinet FortiGuard Labs said the new version of the malware has been behind over 280 million blocked infection attempts worldwide since the start of the year. "Typically delivered through phishing emails containing malicious attachments or links, Snake Keylogger is designed to steal sensitive information from popular web browsers like Chrome, Edge, and Firefox by logging keystrokes, capturing credentials, and monitoring the clipboard," security researcher Kevin Su said . Its other features allow it to exfiltrate the stolen information to an attacker-controlled server using the Simple Mail Transfer Protocol (SMTP) and Telegram bots, allowing the threat actors to access stolen credentials and other sensitive data." What's notable about the latest set of attacks is that it makes use of the AutoIt scripting language ...
