SentinelOne, a cybersecurity firm, has revealed that it was the target of a year-long reconnaissance campaign by China-linked espionage groups, identified as APT15 and UNC5174. This campaign, dubbed "PurpleHaze," involved network reconnaissance and intrusion attempts, ultimately aiming to gather strategic intelligence and potentially establish access for future conflicts. SentinelOne discovered the campaign when the suspected Chinese spies tried to break into the security vendor's own servers in October 2024. The attempted intrusion on SentinelOne's systems failed, but it prompted a deeper investigation into the broader campaign and the malware being used.
The investigation revealed that over 70 organizations across multiple sectors globally were targeted, including a South Asian government entity and a European media organization. The attacks spanned from July 2024 to March 2025 and involved the use of ShadowPad malware and post-exploitation espionage activity. These targeted sectors include manufacturing, government, finance, telecommunications, and research. The coordinated attacks are believed to be connected to Chinese government spying programs. SentinelOne has expressed high confidence that the PurpleHaze and ShadowPad activity clusters can be attributed to China-nexus threat actors. This incident underscores the persistent threat that Chinese cyber espionage actors pose to global industries and public sector organizations. The attack on SentinelOne also highlights that cybersecurity vendors themselves are prime targets for these groups, given their deep visibility into client environments and ability to disrupt adversary operations. SentinelOne recommends that more proactive steps are taken to prevent future attacks. Recommended read:

SentinelOne experienced a significant service disruption on May 29th that lasted approximately seven hours, impacting enterprise customers globally. According to a root-cause analysis released by the company, the outage was triggered by a software flaw within an infrastructure control system. This flaw led to the unintended removal of critical network routes and DNS resolver rules, resulting in widespread loss of network connectivity. SentinelOne has emphasized that the disruption was not the result of a cyberattack, but rather a software glitch in an automated process.
The company explained that the flaw occurred during the transition of its production system to a new cloud-based architecture using infrastructure as code principles. A control system slated for deprecation was triggered by the creation of a new account. A software flaw in the configuration comparison function misidentified discrepancies and incorrectly applied what it believed to be the correct configuration state, overwriting existing network settings. While customer endpoints remained protected, security teams were unable to access management consoles and other related services. The incident primarily affected enterprise customers, hindering their ability to manage security operations and access important data. SentinelOne assured customers that their endpoints continued to operate without interruption and that no security data was lost. Federal customers, including those using GovCloud, were unaffected, though they were notified as a precaution. The company has provided a detailed timeline of the outage, which began at 9:37 a.m. ET and was resolved by 4:05 p.m. ET, and is taking steps to prevent future occurrences. Recommended read:

A joint investigation by SentinelLABS and Validin has exposed a massive cryptocurrency phishing operation named "FreeDrain." This industrial-scale network has been siphoning digital assets for years by exploiting weaknesses in free publishing platforms. FreeDrain utilizes aggressive SEO manipulation, free-tier web services like gitbook.io, webflow.io, and github.io, along with sophisticated layered redirection techniques to lure unsuspecting victims. The operation's primary goal is to steal cryptocurrency wallet login credentials and seed phrases, often resulting in rapid fund exfiltration.
FreeDrain operators achieve high search engine rankings by creating over 38,000 malicious subdomains on trusted platforms, including Amazon S3 and Azure Web Apps. These subdomains host lure pages that often feature AI-generated content and screenshots of legitimate wallet interfaces. When users search for wallet-related queries, they are redirected through comment-spammed URLs and custom redirector domains to highly convincing phishing clones. These phishing pages frequently include live chat widgets manned by real human operators who encourage victims to submit their credentials. Researchers believe the operators are based in the UTC+05:30 timezone (Indian Standard Time) and work standard weekday hours. The sophistication of FreeDrain lies in its scale, automation, and ability to avoid traditional phishing email delivery vectors. Victims are funneled from benign-seeming search queries directly to malicious pages ranked at the top of major search engines. Validin first became aware of FreeDrain on May 12, 2024, after a victim reported losing approximately 8 BTC (around $500,000 at the time) to a phishing site. Recommended read:

Cybersecurity firm SentinelOne has become a prime target for state-sponsored threat actors from China and North Korea. SentinelOne, which provides autonomous endpoint protection using AI and machine learning to Fortune 10 and Global 2000 enterprises, government agencies, and managed service providers, is facing persistent cyber espionage and infiltration attempts. A recent analysis by SentinelOne revealed that Chinese actors are actively targeting both the company and its high-value clients, engaging in reconnaissance activities against SentinelOne’s infrastructure and specific organizations they defend.
SentinelOne uncovered a China-nexus threat cluster dubbed PurpleHaze, which conducted reconnaissance attempts against its infrastructure and some of its high-value customers. Researchers first became aware of this group during a 2024 intrusion against an organization that was previously providing hardware logistics services for SentinelOne employees. PurpleHaze is assessed to be a hacking crew with loose ties to another state-sponsored group known as APT15 and has been observed targeting a South Asian government-supporting entity, employing an operational relay box (ORB) network and a Windows backdoor dubbed GoReShell. North Korean actors have also been targeting SentinelOne, attempting to infiltrate the company through a fake IT worker campaign. The company is tracking approximately 360 fake personas and over 1,000 job applications linked to DPRK IT worker operations applying for roles at SentinelOne and SentinelLabs Intelligence. SentinelOne has warned of threat actors targeting its systems and high-value clients, emphasizing that cybersecurity providers are attractive targets due to the potential for significant compromise and the insights into how thousands of environments and millions of endpoints are protected.
