Fast briefings on active campaigns, exploited vulnerabilities, malware shifts, ransomware activity, and attacker tactics that security teams need to triage quickly.
According to a recent Sophos report, 79% of ransomware attacks begin with stolen credentials and abuse of legitimate logins. Identity-based attacks have replaced exploit-based attacks as the most common initial intrusion method, and enterprises need to rethink their identity security strategies.
Multiple security incidents this week highlight the threats of geopolitical risks, new macOS credential-stealing malware, AI integration vulnerabilities, and supply chain attacks to enterprise security. CISA released vulnerability disclosure guidelines.
Microsoft Threat Intelligence has discovered a new modular malware called GigaWiper that combines backdoors with multiple wiper payloads, allowing attackers to flexibly choose destructive methods according to their needs, posing a serious threat to enterprise data security.
This week, several noteworthy incidents occurred in the global cybersecurity landscape: the U.S. Department of Homeland Security's (DHS) internal information sharing network (HSIN) was breached by hackers, putting sensitive but unclassified data at risk of exposure; Adobe announced it will increase the frequency of security updates to twice a month to address AI-accelerated vulnerability discovery; Canada's Communications Security Establishment (CSE) publicly disclosed for the first time that it had conducted active disruption operations against the infrastructure of foreign hacker groups, successfully blocking the operations of a ransomware gang. In addition, the guilty plea of a Russian-linked ransomware suspect, the sale of the multi-platform malware QuimaRAT on the dark web, and the cross-tenant vulnerability in Writer AI have also highlighted the complexity of the current threat landscape.
In the first half of 2026, global ransomware attacks reached an all-time high, with a 28% year-on-year increase in attacks on the retail industry. This article analyzes attack trends, corporate risks, and defense strategies.
The focus of cybersecurity attacks has shifted from disrupting devices to stealing data. This article analyzes the changes in attack methods, the risks faced by enterprises, and proposes defense recommendations based on identity security, zero trust, and data protection.
This threat briefing analyzes the dual impact of structured content in generative AI and ChatGPT GEO, exploring its security risks and defense strategies in SEO semantic poisoning, information manipulation, and AI understanding bias.
In June 2026, the integration infrastructure of SaaS provider Klue was exploited, leading to the theft of OAuth tokens and data breaches at nearly 200 downstream clients, including security vendors such as Huntress and Recorded Future. Analysis of attack methods, corporate impact, and defense recommendations.
CrowdStrike's 2026 Global Threat Report reveals that prompt injection attacks have impacted over 90 organizations in 2025, with attackers using malicious prompts to steal credentials and cryptocurrency. AI-driven adversary operations have increased by 89% year-over-year, and 82% of intrusions do not involve traditional malware. As enterprises shift from chatbots to AI agents with broad permissions, prompt injection is emerging as a new attack vector. This article provides an in-depth analysis of the technical principles behind this trend, its impact on businesses, and defense strategies.
ShinyHunters' recent attacks on several well-known companies demonstrate that attackers can cause significant damage without malware or zero-day vulnerabilities, relying solely on stolen credentials, OAuth token abuse, and social engineering. This signals that the focus of cybersecurity defense must shift from perimeter protection to identity security.
The CVE-2025-32711 vulnerability (EchoLeak) in Microsoft 365 Copilot allows attackers to achieve zero-click data theft via emails with hidden prompts. This article provides an in-depth analysis of the attack chain, enterprise impact, and mitigation measures for this vulnerability.
Google Threat Intelligence team disclosed that the UNC6508 hacking group has been conducting long-term cyber espionage activities against top medical, military, and AI research institutions in North America, with attack targets covering clinical research, defense technology, and artificial intelligence fields.
This week, multiple major events occurred in the global cybersecurity field: layoffs in Google Cloud's security division sent shockwaves through the industry; an international law enforcement operation dismantled the AudiA6 money laundering network, cutting off the ransomware funding chain; South Korea's Coupang was fined $400 million for a data breach, setting a record for fines in the country. These incidents reflect the deep-seated challenges facing corporate security.
SecurityWeek’s latest weekly report shows that AI is being used more systematically in high-risk stages of attacks, Comodo has an unpatched remote kernel-level vulnerability, and the selection of US CISA leadership has drawn attention. For businesses, these developments collectively point to three categories of steadily rising risk: automated attack capabilities, the exposed surface of edge security devices, and uncertainty in critical cybersecurity governance.
The security developments compiled by SecurityWeek show that AI-powered attacks, unpatched endpoint vulnerabilities, critical infrastructure exposure, and changes in government cybersecurity leadership are all evolving at the same time. For enterprises, this is not just a series of isolated incidents, but a reflection of systemic pressure on identity, endpoints, supply chains, and infrastructure resilience.
Based on the Munich Re 2026 Cyber Risk Trends Report, this article analyzes from an enterprise security perspective why ransomware, data breaches, business email compromise, and distributed denial-of-service attacks remain the primary loss drivers, and why the government, manufacturing, and technology sectors face higher exposure.
Fortinet’s high-risk FortiClient EMS vulnerability patched in April has once again been used in attacks, with attackers leveraging the management platform to deliver info-stealing malware to managed endpoints. This incident shows that once an endpoint management system is compromised, it can quickly escalate into a centralized intrusion risk targeting the entire enterprise endpoint fleet.
