Market research company Klue confirmed that hackers used a credential from a 2022 limited pilot to breach its systems on June 12, stealing OAuth tokens that granted access to customer data stored in third-party clouds and databases. Affected customers include LastPass and several other cybersecurity firms. The hacking group Icarus claimed responsibility and is threatening to release stolen data unless a ransom is paid. Klue has not explained why the four-year-old credential was never revoked after the pilot ended, raising serious questions about its credential management and vendor-access controls.

LastPass xác nhận dữ liệu khách hàng trong môi trường Salesforce bị truy cập sau cuộc tấn công chuỗi cung ứng nhằm vào Klue hôm 12/6. Nhóm tống tiền Icarus đã xâm nhập hạ tầng Klue bằng thông tin đăng nhập cũ, đánh cắp token OAuth kết nối Klue với Salesforce của khách hàng. Dữ liệu bị lộ bao gồm tên, số điện thoại, email, địa chỉ, thông tin hỗ trợ và dữ liệu CRM. LastPass cho biết sản phẩm cốt lõi, dịch vụ và kho dữ liệu khách hàng không bị ảnh hưởng.

Modern phishing attacks have evolved far beyond misspelled domains and fake login pages. Attackers now use ClickFix (tricking users into running malicious terminal commands via fake CAPTCHAs), Browser-in-the-Browser (BitB) attacks that render convincing fake browser windows inside real pages, OAuth consent phishing (ConsentFix) that steals authorization codes without ever asking for a password, device code phishing that abuses legitimate OAuth flows to authorize attacker devices, and fake video conference overlays that prompt malware downloads under the guise of driver updates. Each technique systematically eliminates traditional red flags, weaponizing users' own habits and trusted infrastructure against them. Huntress SAT offers simulated scenarios replicating these exact tactics to build behavioral muscle memory before users encounter the real thing.
Market research company Klue, breached on June 12, is communicating with the hacking group Icarus and believes they are deleting stolen customer data. However, a second unnamed hacker group has emerged, claiming to have obtained Klue's customer data from Icarus and threatening to leak it unless a ransom is paid. The second group alleges 195 affected Klue customers and claims Klue paid Icarus. Klue advises customers contacted by this second group to demand a data sample as proof before taking any action. The original breach involved a 2022 third-party credential that was never revoked, which attackers used to steal OAuth tokens and access customer clouds and databases. Affected companies include Gong, Jamf, HackerOne, Huntress, LastPass, Snyk, and others.
Device code phishing abuses Microsoft's OAuth 2.0 device authorization grant flow, allowing attackers to generate device codes and trick users into authorizing them on legitimate Microsoft login pages. This bypasses MFA by stealing valid OAuth tokens directly. The attack has surged recently, with campaigns like Storm-2372 targeting governments and NGOs, and phishing-as-a-service platforms like EvilTokens and Kali365 now offering it as a commodity service. Key mitigations include enabling Microsoft Entra Conditional Access policies to block device code flow, monitoring new device registrations in Entra, watching for suspicious token exchanges in logs, and disabling device code flow where operationally feasible. Notably, around 25% of organizations that have paid for Conditional Access have not yet configured it, leaving a significant gap.
A Huntress SOC investigation uncovered an Akira ransomware affiliate using an unusual attack chain: the threat actor accessed a hypervisor, spun up a new virtual machine (bypassing installed security tooling), disabled Microsoft Defender, archived target data with WinRAR, and exfiltrated it via Easyupload.io — a file-sharing site now owned by the rebranded LimeWire platform. The VHDX image of the VM provided forensic analysts a clear timeline of attacker activity, including Active Directory enumeration, lateral movement to file servers, and rapid ransomware deployment. The incident highlights how RaaS affiliates adapt TTPs, including creating new VMs to evade endpoint security stacks, and underscores the need to monitor for new endpoint creation within environments.
Mexico's 2025–2030 National Cybersecurity Plan, published by the ATDT in December 2025, outlines a six-phase roadmap to modernize the country's cyber posture. The plan addresses top threats including ransomware, financial malware, hacktivism, state-sponsored attacks, and organized crime. Key milestones include passing a General Cybersecurity Law in 2026, establishing a National Center for Cybersecurity Operations, creating a National Cyber Range by 2027, and integrating AI for cyber defense by 2028. Mexico ranks as a Tier 2 nation in the ITU Global Cybersecurity Index but lags in institutional capacity. The 2026 FIFA World Cup co-hosted by Mexico serves as an immediate stress test for its digital infrastructure. Insikt Group recommends organizations in Mexico adopt international standards like NIST CSF or ISO/IEC 27001, conduct scenario-planning exercises, leverage threat intelligence platforms, and invest in public cyber hygiene education.
Huntress discloses it was among multiple victims of a supply chain attack targeting Klue, a market intelligence platform. The threat actor, dubbed Icarus, compromised Klue's backend systems on June 11, 2026, injecting code to steal OAuth tokens used by Klue's customers to connect their CRM tools. This allowed the attacker to directly query and exfiltrate Salesforce data from Huntress and other companies including Recorded Future, Tanium, and Jamf. The stolen Huntress data includes business contact info, pricing, subscription details, and sales communications — no product telemetry, passwords, or payment data was affected. Huntress shares IOCs (IP addresses, User-Agent strings), threat actor attribution details linking to the Icarus extortion group, and five recommended investigation steps for other potentially impacted organizations. The post is being updated in real time as the situation evolves, with a secondary unauthorized party also claiming access to breach data as of June 24.
Ransomware attacks in Europe surged 55% in the first four months of 2026 compared to the same period in 2025, with France seeing a 119% increase and Italy 92%. Researchers from Black Kite attribute the shift to US market oversaturation and AI-assisted target research pointing attackers toward European organizations. The number of active ransomware groups has grown from 60 in 2023 to 150 today, filling the vacuum left by law enforcement takedowns of major RaaS operations. Manufacturing and digital services sectors are primary targets, largely because attackers exploit supply chain leverage — breaching one vendor to access hundreds of downstream clients, as demonstrated by the Miljödata attack that exposed data from ~200 Swedish municipalities. Experts recommend organizations map fourth- and fifth-party vendor dependencies and rank vendors by risk proactively rather than reactively.
