When talking about credential security, the focus usually lands on breach prevention. This makes sense when IBM’s 2025 Cost of a Data Breach Report puts the average cost of a breach at $4.4 million. Avoiding even one major incident is enough to justify most security investments, but that headline figure obscures the more persistent problems caused by recurring credential incidents. Account lockouts and compromised credentials don’t make the news. They show up as repeated helpdesk tickets, interrupted workflows, and time pulled away from higher-value work. Individually, each incident seems minor, but collectively they place a constant burden on IT teams and the wider business. The real cost doesn’t just sit in the breach you might prevent, but in the day-to-day disruption you’re already dealing with. Repeated incidents equal repeated costs If an organization finds itself suffering from credential-based attacks or repeated account c...

New academic research has identified multiple RowHammer attacks against high-performance graphics processing units (GPUs) that could be exploited to escalate privileges and, in some cases, even take full control of a host. The efforts have been codenamed GPUBreach , GDDRHammer , and GeForge . GPUBreach goes a step further than GPUHammer , demonstrating for the first time that RowHammer bit-flips in GPU memory can induce much more than data corruption and enable privilege escalation, and lead to a full system compromise. "By corrupting GPU page tables via GDDR6 bit-flips, an unprivileged process can gain arbitrary GPU memory read/write, and then chain that into full CPU privilege escalation — spawning a root shell — by exploiting memory-safety bugs in the NVIDIA driver," Gururaj Saileshwar, one of the authors of the study and Assistant Professor at the University of Toronto, said in a post on LinkedIn. What makes GPUBreach notable is that it works eve...

A China-based threat actor known for deploying Medusa ransomware has been linked to the weaponization of a combination of zero-day and N-day vulnerabilities to orchestrate "high-velocity" attacks and break into susceptible internet-facing systems. "The threat actor's high operational tempo and proficiency in identifying exposed perimeter assets have proven successful, with recent intrusions heavily impacting healthcare organizations, as well as those in the education, professional services, and finance sectors in Australia, the United Kingdom, and the United States," the Microsoft Threat Intelligence team said . Attacks mounted by Storm-1175 have also leveraged zero-day exploits, in some cases, before they have been publicly disclosed, as well as recently disclosed vulnerabilities to obtain initial access. Select incidents have involved the threat actor chaining together multiple exploits (e.g., OWASSRF ) for post-compromise activity. Upon...

Threat actors are exploiting a maximum-severity security flaw in Flowise , an open-source artificial intelligence (AI) platform, according to new findings from VulnCheck. The vulnerability in question is CVE-2025-59528 (CVSS score: 10.0), a code injection vulnerability that could result in remote code execution. "The CustomMCP node allows users to input configuration settings for connecting to an external MCP (Model Context Protocol) server," Flowise said in an advisory released in September 2025. "This node parses the user-provided mcpServerConfig string to build the MCP server configuration. However, during this process, it executes JavaScript code without any security validation." Flowise noted that successful exploitation of the vulnerability can allow access to dangerous modules such as child_process (command execution) and fs (file system), as it runs with full Node.js runtime privileges. Put differently, a threat actor who weaponizes the flaw can execu...

An Iran-nexus threat actor is suspected to be behind a password-spraying campaign targeting Microsoft 365 environments in Israel and the U.A.E. amid ongoing conflict in the Middle East. The activity, assessed to be ongoing, was carried out in three distinct attack waves that took place on March 3, March 13, and March 23, 2026, per Check Point. "The campaign is primarily focused on Israel and the U.A.E., impacting more than 300 organizations in Israel and over 25 in the U.A.E.," the Israeli cybersecurity company said . "Activity associated with the same actor was also observed against a limited number of targets in Europe, the United States, the United Kingdom, and Saudi Arabia." The campaign is assessed to have targeted the cloud environments of government entities, municipalities, technology, transportation, energy sector organizations, and private-sector companies in the region. Password spraying is a form of brute-force attack where a...

Threat actors likely associated with the Democratic People's Republic of Korea (DPRK) have been observed using GitHub as command-and-control (C2) infrastructure in multi-stage attacks targeting organizations in South Korea. The attack chain, per Fortinet FortiGuard Labs , involves obfuscated Windows shortcut (LNK) files acting as the starting point to drop a decoy PDF document and a PowerShell script that sets the stage for the next phase of the attack. It's assessed that these LNK files are distributed via phishing emails. As soon as the payloads are downloaded, the victim is displayed the PDF document, while the malicious PowerShell script runs silently in the background. The PowerShell script performs checks to resist analysis by scanning for running processes related to virtual machines, debuggers, and forensic tools. If any of those processes are detected, the script immediately terminates. Otherwise, it extracts a Visual Basic Scri...

Your attack surface no longer lives on one operating system, and neither do the campaigns targeting it. In enterprise environments, attackers move across Windows endpoints, executive MacBooks, Linux infrastructure, and mobile devices, taking advantage of the fact that many SOC workflows are still fragmented by platform.  For security leaders, this creates a costly operational gap : slower validation, limited early-stage visibility, more escalations, and more time for attackers to steal credentials, establish persistence, or move deeper before the response fully begins. The Multi-OS Attack Problem SOCs Aren’t Ready For A multi-OS attack can turn one threat into several different investigations at once. The campaign may follow a different path depending on the system it reaches, which breaks the speed and consistency SOC teams rely on during early triage. Instead of moving through one clear validation pro...
