A proof-of-concept (PoC) exploit for a critical Microsoft SharePoint vulnerability, published by cybersecurity company Rapid7 on Tuesday, is already being used in attacks. Tracked as CVE-2026-55040, this authentication bypass security flaw in the JWT token validation pipeline can be exploited by attackers without privileges to perform operations as a SharePoint site user or administrator. Microsoft patched the vulnerability as part of the July 2026 Patch Tuesday updates, when it warned customers to patch systems running SharePoint Enterprise Server 2016 and SharePoint Server 2019. "The authentication feature could be bypassed as this vulnerability allows impersonation," it said. "Exploiting this vulnerability could allow an attacker to disclose files and modify data, but the attacker cannot impact the availability of the system."
A newly disclosed flaw in the way OpenAI, Anthropic, and Google carried hidden AI reasoning between API calls let researchers recover internal reasoning and secrets from session logs, including API keys and passwords. The weakness affected encrypted reasoning objects used by the providers' reasoning APIs, where a block created in one session could be replayed into another and, during testing,
Two malicious LiteLLM releases sat on PyPI for about 40 minutes in March carrying credential-stealing code capable of harvesting cloud keys, SSH keys, Kubernetes tokens, database passwords, and other secrets from systems that installed them. Threat intelligence firm CloudSEK now says a dataset it obtained, built from roughly 434,000 files the attackers captured, maps potential exposure to more
SAP has released patches to address a maximum-severity security flaw impacting Commerce Cloud (Data Hub Adapter) that could result in arbitrary code execution. The vulnerability, assigned the CVE identifier CVE-2026-58231, is rated 10.0 on the CVSS scoring system. It has been described as a case of insufficient authorization checks and input validation. "SAP Commerce Cloud allows an
Global supply chain and distribution giant Wesco has confirmed in a statement to BleepingComputer that it is investigating a cybersecurity incident. The company's statement comes after data extortion group ExfilSquad claimed to have stolen sensitive information from Wesco and leaked it on their data leak site. Jennifer Sniderman, Vice President of Corporate Communications at Wesco, said that the incident involves the company's cloud CRM environment. “Wesco is aware of a claim of CRM data exfiltration by a third party,” Sniderman told BleepingComputer. “We have worked with our cloud CRM vendor on the matter, and we do not believe that there is a risk to sensitive data.” The company representative added that Wesco has not experienced any business disruption, and all operations continue as normal.
AI is making phishing, credential theft, and social engineering faster and more efficient, while traditional trust signals such as passwords, MFA, IP reputation, and geolocation become easier to bypass. Specops explains why organizations are increasingly adding device trust to their Zero Trust strategies. Security research like this is a reminder that visibility into endpoints, identity, and network traffic remains the foundation of any effective defense program. Beyond patching, organizations should inventory exposed services, disable unused functionality, and require multi-factor authentication wherever it can be deployed.
A seller claims to offer Israel’s 2026 population registry, but checks show the 9.2 million records are authentic data dating back to 2005. A vendor on a well-known leak forum claims to have breached Israel’s Population and Immigration Authority and is selling the entire national registry, 9.2 million records covering essentially the whole country. Ransomnews […] The reporting underscores the importance of treating third-party software and infrastructure as part of your own attack surface, since trust in a vendor is only as strong as the vendor’s own security posture. Beyond patching, organizations should inventory exposed services, disable unused functionality, and require multi-factor authentication wherever it can be deployed.
North Korea's state hackers are no longer content to type prompts into public chatbots. One of the country's main espionage groups has begun running artificial intelligence (AI) offline on its own servers, connecting document-search tools to files in its possession, and collecting the software parts needed to build AI into its malware. South Korean security firm Genians says it uncovered the The incident highlights how adversaries continue to evolve their tradecraft, combining increasingly accessible tooling with targeted social engineering to slip past traditional perimeter defenses. Finally, maintain offline, tested backups and a clear communication plan so that business continuity decisions are made ahead of time rather than under pressure.
LexisNexis took its Diligence, Metabase API, and Newsdesk services offline as part of its response to unusual activity on servers hosted and managed by an unnamed third-party vendor. This development is consistent with broader industry trends, where threat actors increasingly reuse proven techniques and commodity tooling rather than investing in novel malware. Security teams should review their detection rules, keep threat-intelligence feeds current, and validate that incident-response runbooks are tested before an incident occurs.
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) warned that hackers are exploiting a critical-severity Progress Kemp LoadMaster command injection vulnerability. Because attacks of this type can go unnoticed for extended periods, the window between initial compromise and detection is often the deciding factor in the eventual impact. Beyond patching, organizations should inventory exposed services, disable unused functionality, and require multi-factor authentication wherever it can be deployed.
