SonicWall on Wednesday disclosed that an unauthorized party accessed firewall configuration backup files for all customers who have used the cloud backup service. "The files contain encrypted credentials and configuration data; while encryption remains in place, possession of these files could increase the risk of targeted attacks," the company said . It also noted that it's working to notify all partners and customers, adding it has released tools to assist with device assessment and remediation. The company is also urging users to log in and check for their devices. The development comes a couple of weeks after SonicWall urged customers to perform a credential reset after their firewall configuration backup files were exposed in a security breach impacting MySonicWall accounts. The list of impacted devices available on the MySonicWall portal has been assigned a priority level to help customers prioritize remediation efforts. The labels are as follows - Active –...

Cyber threats are evolving faster than ever. Attackers now combine social engineering, AI-driven manipulation, and cloud exploitation to breach targets once considered secure. From communication platforms to connected devices, every system that enhances convenience also expands the attack surface.

Token theft is a leading cause of SaaS breaches. Discover why OAuth and API tokens are often overlooked and how security teams can strengthen token hygiene to prevent attacks. Most companies in 2025 rely on a whole range of software-as-a-service (SaaS) applications to run their operations. However, the security of these applications depends on small pieces of data called tokens. Tokens, like OAuth access tokens, API keys, and session tokens, work like keys to these applications. If a cybercriminal gets hold of one, they can access relevant systems without much trouble. Recent security breaches have shown that just one stolen token can bypass multi-factor authentication (MFA) and other security measures. Instead of exploiting vulnerabilities directly, attackers are leveraging token theft. It's a security concern that ties into the broader issue of SaaS sprawl and the difficulty of monitoring countless third-party integrations. Recent Breaches Involving Token Theft A lot of real-wo...

Russian hackers' adoption of artificial intelligence (AI) in cyber attacks against Ukraine has reached a new level in the first half of 2025 (H1 2025), the country's State Service for Special Communications and Information Protection (SSSCIP) said. "Hackers now employ it not only to generate phishing messages, but some of the malware samples we have analyzed show clear signs of being generated with AI – and attackers are certainly not going to stop there," the agency said in a report published Wednesday. SSSCIP said 3,018 cyber incidents were recorded during the time period, up from 2,575 in the second half of 2024 (H2 2024). Local authorities and military entities witnessed an increase in attacks compared to H2 2024, while those targeting government and energy sectors declined. One notable attack observed involved UAC-0219's use of malware called WRECKSTEEL in attacks aimed at state administration bodies and critical infrastructure facilities in the country...

Threat actors are actively exploiting a critical security flaw impacting the Service Finder WordPress theme that makes it possible to gain unauthorized access to any account, including administrators, and take control of susceptible sites. The authentication bypass vulnerability, tracked as CVE-2025-5947 (CVSS score: 9.8), affects the Service Finder Bookings, a WordPress plugin bundled with the Service Finder theme. It was discovered by a researcher who goes by the name Foxyyy. "This vulnerability makes it possible for an unauthenticated attacker to gain access to any account on a site, including accounts with the 'administrator' role," Wordfence researcher István Márton said . The problem, at its core, is a case of privilege escalation stemming from authentication bypass due to the plugin not adequately validating a user's cookie value before logging them in through an account switching function (service_finder_switch_back()). As a result, an unauthenticate...

Cybersecurity researchers are calling attention to a nefarious campaign targeting WordPress sites to make malicious JavaScript injections that are designed to redirect users to sketchy sites. "Site visitors get injected content that was drive-by malware like fake Cloudflare verification," Sucuri researcher Puja Srivastava said in an analysis published last week. The website security company said it began an investigation after one of its customer's WordPress sites served suspicious third-party JavaScript to site visitors, ultimately finding that the attackers introduced malicious modifications to a theme-related file ("functions.php"). The code inserted into "functions.php" incorporates references to Google Ads, likely in an attempt to evade detection. But, in reality, it functions as a remote loader by sending an HTTP POST request to the domain "brazilc[.]com," which, in turn, responds with a dynamic payload that includes two component...

Threat actors with suspected ties to China have turned a legitimate open-source monitoring tool called Nezha into an attack weapon, using it to deliver a known malware called Gh0st RAT to targets. The activity, observed by cybersecurity company Huntress in August 2025, is characterized by the use of an unusual technique called log poisoning (aka log injection) to plant a web shell on a web server. "This allowed the threat actor to control the web server using ANTSWORD , before ultimately deploying Nezha, an operation and monitoring tool that allows commands to be run on a web server," researchers Jai Minton, James Northey, and Alden Schmidt said in a report shared with The Hacker News. In all, the intrusion is said to have likely compromised more than 100 victim machines, with a majority of the infections reported in Taiwan, Japan, South Korea, and Hong Kong. "The activity has been going on since at least June of 2025 but it may have been longer," Minton, ...

Three prominent ransomware groups DragonForce , LockBit , and Qilin have announced a new strategic ransomware alliance, once underscoring continued shifts in the cyber threat landscape. The coalition is seen as an attempt on the part of the financially motivated threat actors to conduct more effective ransomware attacks, ReliaQuest said in a report shared with The Hacker News. "Announced shortly after LockBit's return, the collaboration is expected to facilitate the sharing of techniques, resources, and infrastructure, strengthening each group's operational capabilities," the company noted in its ransomware report for Q3 2025. "This alliance could help restore LockBit's reputation among affiliates following last year's takedown, potentially triggering a surge in attacks on critical infrastructure and expanding the threat to sectors previously considered low risk." The partnership with Qilin is no surprise, given that it has become the most a...

Cybersecurity researchers have disclosed details of a now-patched vulnerability in the popular figma-developer-mcp Model Context Protocol ( MCP ) server that could allow attackers to achieve code execution. The vulnerability, tracked as CVE-2025-53967 (CVSS score: 7.5), is a command injection bug stemming from the unsanitized use of user input, opening the door to a scenario where an attacker can send arbitrary system commands. "The server constructs and executes shell commands using unvalidated user input directly within command-line strings. This introduces the possibility of shell metacharacter injection (|, >, &&, etc.)," according to a GitHub advisory for the flaw. "Successful exploitation can lead to remote code execution under the server process's privileges." Given that the Framelink Figma MCP server exposes various tools to perform operations in Figma using artificial intelligence (AI)-powered coding agents like Cursor, an attacker co...

Artificial intelligence is reshaping cybersecurity on both sides of the battlefield. Cybercriminals are using AI-powered tools to accelerate and automate attacks at a scale defenders have never faced before. Security teams are overwhelmed by an explosion of vulnerability data, tool outputs, and alerts, all while operating with finite human resources. The irony is that while AI has become a dominant theme in cybersecurity, many enterprises still struggle to apply it effectively within their programs.  The problem isn't access to information, as teams already have more data than they can process. It's cutting through the noise and focusing on what truly matters. AI is crucial here. Not only can it make security teams more efficient, it can generate insights that would be impossible to gather at scale or in real time without machine assistance. If adversaries are already weaponizing AI, then defenders must embed it into their strategies as well or risk falling further behind in a fi...

OpenAI on Tuesday said it disrupted three activity clusters for misusing its ChatGPT artificial intelligence (AI) tool to facilitate malware development. This includes a Russian‑language threat actor, who is said to have used the chatbot to help develop and refine a remote access trojan (RAT), a credential stealer with an aim to evade detection. The operator also used several ChatGPT accounts to prototype and troubleshoot technical components that enable post‑exploitation and credential theft. "These accounts appear to be affiliated with Russian-speaking criminal groups, as we observed them posting evidence of their activities in a Telegram channel dedicated to those actors," OpenAI said. The AI company said while its large language models (LLMs) refused the threat actor's direct requests to produce malicious content, they worked around the limitation by creating building-block code, which was then assembled to create the workflows. Some of the produced output invo...

A Vietnamese threat actor named BatShadow has been attributed to a new campaign that leverages social engineering tactics to deceive job seekers and digital marketing professionals to deliver a previously undocumented malware called Vampire Bot. "The attackers pose as recruiters, distributing malicious files disguised as job descriptions and corporate documents," Aryaka Threat Research Labs researchers Aditya K Sood and Varadharajan K said in a report shared with The Hacker News. "When opened, these lures trigger the infection chain of a Go-based malware." The attack chains, per the cybersecurity company, leverage ZIP archives containing decoy PDF documents along with malicious shortcut (LNK) or executable files that are masked as PDF to trick users into opening them. When launched, the LNK file runs an embedded PowerShell script that reaches out to an external server to download a lure document, a PDF for a marketing job at Marriott. The PowerShell script al...
