The North Korean threat actors behind the Contagious Interview campaign have been observed using updated versions of a cross-platform malware called OtterCookie with capabilities to steal credentials from web browsers and other files. NTT Security Holdings, which detailed the new findings, said the attackers have "actively and continuously" updated the malware, introducing versions v3 and v4 in February and April 2025, respectively. The Japanese cybersecurity company is tracking the cluster under the name WaterPlum , which is also known as CL-STA-0240, DeceptiveDevelopment, DEV#POPPER, Famous Chollima, PurpleBravo, and Tenacious Pungsan. OtterCookie was first documented by NTT last year after having observed it in attacks since September 2024. Delivered by means of a JavaScript payload via a malicious npm package, trojanized GitHub or Bitbucket repository, or a bogus videoconferencing app, it's designed to contact an external server to execute commands on compromis...

Security Service Edge (SSE) platforms have become the go-to architecture for securing hybrid work and SaaS access. They promise centralized enforcement, simplified connectivity, and consistent policy control across users and devices. But there's a problem: they stop short of where the most sensitive user activity actually happens—the browser. This isn't a small omission. It's a structural limitation. And it's leaving organizations exposed in the one place they can't afford to be: the last mile of user interaction. A new report Reevaluating SSEs: A Technical Gap Analysis of Last-Mile Protection analyzing gaps in SSE implementations reveals where current architectures fall short—and why many organizations are reevaluating how they protect user interactions inside the browser. The findings point to a fundamental visibility challenge at the point of user action. SSEs deliver value for what they're designed to do—enforce network-level policies and route traffic securely between en...

Microsoft Entra ID (formerly Azure Active Directory) is the backbone of modern identity management, enabling secure access to the applications, data, and services your business relies on. As hybrid work and cloud adoption accelerate, Entra ID plays an even more central role — managing authentication, enforcing policy, and connecting users across distributed environments. That prominence also makes it a prime target. Microsoft reports over 600 million attacks on Entra ID every day. These aren't just random attempts, but include coordinated, persistent, and increasingly automated campaigns designed to exploit even small vulnerabilities. Which brings us to the core question: Are Entra ID's native protections enough? Where do they fall short — and what steps should you take to close the gaps and ensure you're covered? Understanding Entra ID At its core, Microsoft Entra ID is your enterprise identity and access management system. It defines how users prove who they are, what resources...

The threat actors known as Golden Chickens have been attributed to two new malware families dubbed TerraStealerV2 and TerraLogger, suggesting continued development efforts to fine-tune and diversify their arsenal. "TerraStealerV2 is designed to collect browser credentials, cryptocurrency wallet data, and browser extension information," Recorded Future Insikt Group said . "TerraLogger, by contrast, is a standalone keylogger. It uses a common low-level keyboard hook to record keystrokes and writes the logs to local files." Golden Chickens, also known as TA4557 and Venom Spider, is the name given to a financially motivated threat actor linked to a notorious malware family called More_eggs . It's known to be active since at least 2018, offering its warez under a malware-as-a-service (MaaS) model. Campaigns distributing More_eggs entail the use of spear-phishing emails to target hiring managers using fake resumes, allowing attackers to steal confidential data. ...

Various generative artificial intelligence (GenAI) services have been found vulnerable to two types of jailbreak attacks that make it possible to produce illicit or dangerous content. The first of the two techniques, codenamed Inception, instructs an AI tool to imagine a fictitious scenario, which can then be adapted into a second scenario within the first one where there exists no safety guardrails . "Continued prompting to the AI within the second scenarios context can result in bypass of safety guardrails and allow the generation of malicious content," the CERT Coordination Center (CERT/CC) said in an advisory released last week. The second jailbreak is realized by prompting the AI for information on how not to reply to a specific request.  "The AI can then be further prompted with requests to respond as normal, and the attacker can then pivot back and forth between illicit questions that bypass safety guardrails and normal prompts," CERT/CC added. Success...

Phishing attacks remain a huge challenge for organizations in 2025. In fact, with attackers increasingly leveraging identity-based techniques over software exploits, phishing arguably poses a bigger threat than ever before.  Attackers are increasingly leveraging identity-based techniques over software exploits, with phishing and stolen credentials (a byproduct of phishing) now the primary cause of breaches. Source: Verizon DBIR Attackers are increasingly leveraging identity-based techniques over software exploits, with phishing and stolen credentials (a byproduct of phishing) now the primary cause of breaches. Source: Verizon DBIR Attackers are turning to identity attacks like phishing because they can achieve all of the same objectives as they would in a traditional endpoint or network attack, simply by logging into a victim's account. And with organizations now using hundreds of internet apps across their workforce, the scope of accounts that can be phished or targeted with s...

The China-linked cyber espionage group tracked as Lotus Panda has been attributed to a campaign that compromised multiple organizations in an unnamed Southeast Asian country between August 2024 and February 2025. "Targets included a government ministry, an air traffic control organization, a telecoms operator, and a construction company," the Symantec Threat Hunter Team said in a new report shared with The Hacker News. "The attacks involved the use of multiple new custom tools, including loaders, credential stealers, and a reverse SSH tool." The intrusion set is also said to have targeted a news agency located in another country in Southeast Asia and an air freight organization located in another neighboring country.  The threat cluster, per Broadcom's cybersecurity division, is assessed to be a continuation of a campaign that was disclosed by the company in December 2024 as targeting various high-profile organizations in Southeast Asia since at least Oct...

The Computer Emergency Response Team of Ukraine (CERT-UA) has revealed a new set of cyber attacks targeting Ukrainian institutions with information-stealing malware. The activity is aimed at military formations, law enforcement agencies, and local self-government bodies, particularly those located near Ukraine's eastern border, the agency said. The attacks involve distributing phishing emails containing a macro-enabled Microsoft Excel spreadsheet (XLSM), which, when opened, facilities the deployment of two pieces of malware, a PowerShell script taken from the PSSW100AVB ("Powershell Scripts With 100% AV Bypass") GitHub repository that opens a reverse shell, and a previously undocumented stealer dubbed GIFTEDCROOK. "File names and email subject lines reference relevant and sensitive issues such as demining, administrative fines, UAV production, and compensation for destroyed property," CERT-UA said. "These spreadsheets contain malicious code which, ...
