Cybersecurity company SentinelOne has revealed that a China-nexus threat cluster dubbed PurpleHaze conducted reconnaissance attempts against its infrastructure and some of its high-value customers. "We first became aware of this threat cluster during a 2024 intrusion conducted against an organization previously providing hardware logistics services for SentinelOne employees," security researchers Tom Hegel, Aleksandar Milenkoski, and Jim Walter said in an analysis published Monday. PurpleHaze is assessed to be a hacking crew with loose ties to another state-sponsored group known as APT15 , which is also tracked as Flea, Nylon Typhoon (formerly Nickel), Playful Taurus, Royal APT, and Vixen Panda. The adversarial collective has also been observed targeting an unnamed South Asian government-supporting entity in October 2024, employing an operational relay box (ORB) network and a Windows backdoor dubbed GoReShell. The implant, written in the Go programming language, repurp...

Find out how Reco keeps Microsoft 365 Copilot safe by spotting risky prompts, protecting data, managing user access, and identifying threats - all while keeping productivity high. Microsoft 365 Copilot promises to boost productivity by turning natural language prompts into actions. Employees can generate reports, comb through data, or get instant answers just by asking Copilot.  However, alongside this convenience comes serious security concerns. Copilot operates across a company's SaaS apps (from SharePoint to Teams and beyond), which means a careless prompt or a compromised user account could expose troves of sensitive information.  Security experts warn that organizations shouldn't assume default settings will keep them safe. Without proactive controls, every file in your organization could be accessible via Copilot. A malicious actor might use Copilot to discover and exfiltrate confidential data without having to manually search through systems. With the right prom...

Google has revealed that it observed 75 zero-day vulnerabilities exploited in the wild in 2024, down from 98 in 2023 but an increase from 63 the year before. Of the 75 zero-days, 44% of them targeted enterprise products. As many as 20 flaws were identified in security software and appliances. "Zero-day exploitation of browsers and mobile devices fell drastically, decreasing by about a third for browsers and by about half for mobile devices compared to what we observed last year," the Google Threat Intelligence Group (GTIG) said in a report shared with The Hacker news. "Exploit chains made up of multiple zero-day vulnerabilities continue to be almost exclusively (~90%) used to target mobile devices." While Microsoft Windows accounted for 22 of the zero-day flaws exploited in 2024, Apple's Safari had three, iOS had two, Android had seven, Chrome had seven, and Mozilla Firefox had one flaw that were abused during the same period. Three of the seven zero-days ...

If you invite guest users into your Entra ID tenant, you may be opening yourself up to a surprising risk.  A gap in access control in Microsoft Entra's subscription handling is allowing guest users to create and transfer subscriptions into the tenant they are invited into, while maintaining full ownership of them.  All the guest user needs are the permissions to create subscriptions in their home tenant, and an invitation as a guest user into an external tenant. Once inside, the guest user can create subscriptions in their home tenant, transfer them into the external tenant, and retain full ownership rights. This stealthy privilege escalation tactic allows a guest user to gain a privileged foothold in an environment where they should only have limited access. Many organizations treat guest accounts as low-risk based on their temporary, limited access, but this behavior, which works as designed, opens the door to known attack paths and lateral movement within the resource t...

In a new campaign detected in March 2025, senior members of the World Uyghur Congress (WUC) living in exile have been targeted by a Windows-based malware that's capable of conducting surveillance. The spear-phishing campaign involved the use of a trojanized version of a legitimate open-source word processing and spell check tool called UyghurEdit++ developed to support the use of the Uyghur language. "Although the malware itself was not particularly advanced, the delivery of the malware was extremely well customized to reach the target population and technical artifacts show that activity related to this campaign began in at least May of 2024," the Citizen Lab said in a Monday report. The investigation, according to the digital rights research laboratory based at the University of Toronto, was prompted after the targets received notifications from Google warning that their accounts had been at the receiving end of government-backed attacks. Some of these alerts we...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Monday added two high-severity security flaws impacting Broadcom Brocade Fabric OS and Commvault Web Server to its Known Exploited Vulnerabilities ( KEV ) catalog, citing evidence of active exploitation in the wild. The vulnerabilities in question are listed below - CVE-2025-1976 (CVSS score: 8.6) - A code injection flaw affecting Broadcom Brocade Fabric OS that allows a local user with administrative privileges to execute arbitrary code with full root privileges CVE-2025-3928 (CVSS score: 8.7) - An unspecified flaw in the Commvault Web Server that allows a remote, authenticated attacker to create and execute web shells "Exploiting this vulnerability requires a bad actor to have authenticated user credentials within the Commvault Software environment," Commvault said in an advisory released in February 2025. "Unauthenticated access is not exploitable. For software customers, this means your ...

What happens when cybercriminals no longer need deep skills to breach your defenses? Today's attackers are armed with powerful tools that do the heavy lifting — from AI-powered phishing kits to large botnets ready to strike. And they're not just after big corporations. Anyone can be a target when fake identities, hijacked infrastructure, and insider tricks are used to slip past security unnoticed. This week's threats are a reminder: waiting to react is no longer an option. Every delay gives attackers more ground. ⚡ Threat of the Week Critical SAP NetWeaver Flaw Exploited as 0-Day — A critical security flaw in SAP NetWeaver (CVE-2025-31324, CVSS score: 10.0) has been exploited by unknown threat actors to upload JSP web shells with the goal of facilitating unauthorized file uploads and code execution. The attacks have also been observed using the Brute Ratel C4 post-exploitation framework, as well as a well-known technique called Heaven's Gate to bypass endpoint protections. ...

Not every security vulnerability is high risk on its own - but in the hands of an advanced attacker, even small weaknesses can escalate into major breaches. These five real vulnerabilities, uncovered by Intruder's bug-hunting team, reveal how attackers turn overlooked flaws into serious security incidents. 1. Stealing AWS Credentials with a Redirect Server-Side Request Forgery (SSRF) is a common vulnerability that can have a significant impact, especially in cloud-hosted applications. If a web application fetches resources from user-supplied URLs, care should be taken to ensure attackers can't manipulate requests to access unintended resources. While assessing a home-moving app running in AWS, our team tested common SSRF bypass techniques. The attack chain was as follows: the app sent a webhook request to the attacker's web server, which responded with a 302 redirect to AWS's metadata service. The app followed the redirect and logged the response, which exposed sensitive metadat...

Government and telecommunications sectors in Southeast Asia have become the target of a "sophisticated" campaign undertaken by a new advanced persistent threat (APT) group called Earth Kurma since June 2024. The attacks, per Trend Micro, have leveraged custom malware, rootkits, and cloud storage services for data exfiltration. The Philippines, Vietnam, Thailand, and Malaysia are among the prominent targets. "This campaign poses a high business risk due to targeted espionage, credential theft, persistent foothold established through kernel-level rootkits, and data exfiltration via trusted cloud platforms," security researchers Nick Dai and Sunny Lu said in an analysis published last week. The threat actor's activities date back to November 2020, with the intrusions primarily relying on services like Dropbox and Microsoft OneDrive to siphon sensitive data using tools like TESDAT and SIMPOBOXSPY. Two other noteworthy malware families in its arsenal include r...

Cybersecurity researchers are warning about a large-scale phishing campaign targeting WooCommerce users with a fake security alert urging them to download a "critical patch" but deploy a backdoor instead. WordPress security company Patchstack described the activity as sophisticated and a variant of another campaign observed in December 2023 that employed a fake CVE ploy to breach sites running the popular content management system (CMS). Given the similarities in the phishing email lures, the bogus web pages, and the identical methods employed to conceal the malware, it's believed the latest attack wave is either the work of the same threat actor or it's a new cluster closely mimicking the earlier one. "They claim the targeted websites are impacted by a (non-existent) 'Unauthenticated Administrative Access' vulnerability, and they urge you to visit their phishing website, which uses an IDN homograph attack to disguise itself as the official WooComm...

Threat actors have been observed exploiting two newly disclosed critical security flaws in Craft CMS in zero-day attacks to breach servers and gain unauthorized access.
