ExfilSquad targets 13 organizations, exploiting cloud portals for data theft and using torrents to spread stolen information and amplify damage. Resecurity is tracking the activity of ExfilSquad – the group announced new victims this week. ExfilSquad is a new cybercrime group that emerged in mid-2026. Instead of using ransomware, it steals data and threatens to […]

The ransomware group known as DeadLock has been observed using decentralized infrastructure to facilitate victim communications and data leak operations in a bid to improve operational resilience. "Its recovery ecosystem combines the Session messaging network with blockchain-backed services that store and deliver resources used throughout the extortion process," the Microsoft Threat Intelligence team said. The tech giant said it observed the ransomware being deployed by multiple threat actors, including an affiliate for Lynx and INC ransomware. DeadLock was first detected in July 2025, employing double extortion tactics to encrypt victim environments and apply pressure by threatening to publicly release exfiltrated data. As of this month, the group has claimed 96 victims, with most of them located in Italy, Spain, Poland, Türkiye, and the U.S.
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 agents can improvise beyond the intended scope of a task when they are given broad access to enterprise systems and data. Token Security explains why organizations need to define agent intent and continuously enforce permissions around what each agent was actually created to do. [...]
CISA confirmed today that ransomware gangs have begun abusing a high-severity Microsoft SharePoint remote code execution vulnerability, which has been flagged as actively exploited since early July. Tracked as CVE-2026-45659, this security flaw stems from a deserialization of untrusted data weakness and allows attackers with low privileges to execute arbitrary code on unpatched SharePoint servers. It can also be exploited in low-complexity attacks because (as Microsoft explained in May when it released security updates for SharePoint Enterprise Server 2016, SharePoint Server 2019, and SharePoint Server Subscription Edition) "an attacker does not require significant prior knowledge of the system and can achieve repeatable success with the payload against the vulnerable component." The U.S. Cybersecurity and Infrastructure Security Agency (CISA) added the vulnerability to its Known Exploited Vulnerabilities Catalog (KEV) on July 1, ordering Federal Civilian Executive Branch (FCEB) agencies to secure their servers within three days.
Windows Plug and Play can be abused to fetch signed vendor software for an emulated USB device and execute privileged installation components that researchers chained to SYSTEM access on a fully updated Windows 11 machine. The same PnP path can be triggered over Remote Desktop without physical hardware when supported Plug and Play or low-level USB redirection is enabled; Microsoft says that
U.S. federal agencies and South Korea's National Policy Agency warned government and critical infrastructure organizations worldwide to secure their systems against Gunra ransomware attacks. Ransomware operators in this campaign appear to follow the double-extortion playbook, threatening to publish stolen data if the ransom demand is not met. Finally, maintain offline, tested backups and a clear communication plan so that business continuity decisions are made ahead of time rather than under pressure.
Cybersecurity and intelligence agencies from South Korea and the U.S. warned of Gunra ransomware attacks targeting critical infrastructure sectors and organizations across the world. Targets of these attacks include healthcare and public health, financial services, government services and facilities, and professional and nonprofit services.

Cybersecurity and intelligence agencies from South Korea and the U.S. warned of Gunra ransomware attacks targeting critical infrastructure sectors and organizations across the world. Targets of these attacks include healthcare and public health, financial services, government services and facilities, and professional and nonprofit services. "Gunra is another variant in the ongoing trend of ransomware attacks causing disruption and harm to U.S. and international organizations," CISA Acting Executive Assistant Director for Cybersecurity, Chris Butera, said. Attacks deploying the ransomware have leveraged security flaws in internet-facing Schneider Electric PowerLogic P5 (CVE-2024-5559) and Fortinet FortiOS and FortiProxy (CVE-2025-24472) appliances to obtain initial access, and then deploy the Gunra ransomware as part of a double extortion model that combines data exfiltration and data encryption for maximum impact.
