LastPass experienced a security incident through Klue, a third-party market intelligence platform integrated with its Salesforce and Gong systems. On June 12, 2026, LastPass was notified that an unauthorized actor exploited stolen OAuth tokens held by Klue to access customer relationship management data within LastPass's Salesforce environment. The exposed information includes customer names, email addresses, phone numbers, physical addresses, support case data, and sales records. Multiple Klue customers were affected by this supply chain attack. LastPass confirmed no Gong data was accessed, and customer vaults, master passwords, and encrypted vault data remain unaffected. The company has terminated Klue access, rotated compromised API tokens, and is cooperating with law enforcement while warning customers about potential phishing attempts using the exposed contact information.

On June 11, 2026, the Icarus threat group compromised Klue's backend systems, a market intelligence platform used by hundreds of enterprises to sync competitive battlecard data with CRM environments. The attackers exploited a dormant credential from an abandoned prototype integration to harvest OAuth tokens for Salesforce and Gong. Through automated API calls using Python scripts, the group exfiltrated CRM data including business contacts, price quotes, and sales communications from multiple customer Salesforce organizations. Klue detected the anomalous activity on June 12 and revoked OAuth credentials on June 13. The attackers subsequently launched an extortion campaign starting June 16, demanding victims contact them via Session Messenger within 48 hours.

In June 2026, a compromised Klue competitive-intelligence platform integration was exploited to exfiltrate customer relationship management data from enterprise Salesforce environments. Attackers authenticated through compromised Klue service accounts, generated OAuth tokens, and executed automated Python scripts to conduct bulk data extraction via Salesforce REST API queries over approximately 24 hours. The activity included concentrated bursts of nearly a thousand queries within 15 minutes and sustained extraction windows exceeding 6 hours. This incident follows similar third-party OAuth-abuse campaigns targeting Salesforce through Salesloft Drift and Gainsight integrations throughout 2025 and 2026. While the tactics resemble operations attributed to ShinyHunters and UNC6395 threat groups, attribution remains uncertain. The initial access vector, full scope of exfiltration, and attacker intent are still under investigation, with no extortion demands observed to date.

The 2026 FIFA World Cup presents a concentrated attack surface spanning three nations, 16 cities, and billions of viewers. Cybercriminals have already launched phishing campaigns, fraudulent ticket sales, and brand impersonation schemes targeting governments, sponsors, broadcasters, transportation providers, and telecommunications companies. Financially motivated actors are exploiting tournament-related interest through credential theft and payment fraud. Hacktivist and state-aligned groups, including pro-Iranian actors like Handala and CyberAv3ngers, may conduct DDoS attacks, website defacements, or espionage operations amid heightened geopolitical tensions involving Iran, the United States, and Russia. Ransomware groups such as Qilin, DragonForce, Akira, and Play may target organizations reliant on continuous service availability. Thousands of FIFA-themed domains have been registered, many exhibiting characteristics associated with fraud campaigns. Organizations throughout the ecosystem face elevated ris...

An advanced voicemail-themed phishing campaign is utilizing HTML attachments to hijack Microsoft 365 sessions through silent OAuth exploitation. Emails arrive spoofing legitimate businesses with fake voicemail notifications containing embedded HTML files. When victims click the play button, the kit triggers a rogue OAuth 2.0 request using the prompt=none parameter to steal authentication tokens from active M365 sessions. If no active session exists, victims are redirected to credential harvesters hosted on compromised infrastructure, specifically a Turkish domain hosting over 100 active campaign directories. The operation includes multiple attack vectors: fake login portals mimicking DocuSign, Outlook and Google, OAuth device code phishing interfaces, and RMM deployment disguised as document viewers. This represents a sophisticated Phishing-as-a-Service operation deploying concurrent attack types from consolidated infrastructure.

Threat actors are increasingly leveraging the global interest in artificial intelligence by impersonating popular AI platforms such as ChatGPT, Copilot, DeepSeek, and Claude in social engineering campaigns. These operations span phishing attacks, malvertising, and search engine optimization-driven tactics that ultimately lead to credential theft, financial fraud, or malware infections. Observed campaigns include ChatGPT-themed phishing collecting credit card data targeting South Africa, Claude-themed adversary-in-the-middle attacks harvesting credentials and access tokens, malvertising campaigns distributing Vidar stealer through fake AI plugin downloads, and fraudulent DeepSeek V4 installers on GitHub. The initial access broker Storm-3075 has been identified employing AI-themed malvertising, while the financially motivated actor Fox Tempest provides malware-signing-as-a-service to enhance payload legitimacy. These campaigns combine traditional social engineering tactics with AI branding to improve success...

A significant expansion of the Kali365 phishing-as-a-service operation has been observed, now targeting multiple platforms beyond Microsoft 365. The operator abuses OAuth 2.0 device authorization flows to bypass MFA and steal authentication tokens. Key discoveries include a live command-and-control panel infrastructure, a phishing campaign impersonating MAX Messenger (Russia's state-backed messaging platform with 110 million users) through fake prize-claim flows, and a cluster of 126 malicious hosts impersonating services including Microsoft Outlook, Okta SSO, Xerox DocuShare, Mail.ru, Yandex Disk, and Odnoklassniki. The operation demonstrates a deliberate focus on Russian consumer platforms alongside Western enterprise targets, utilizing Telegram bots for credential exfiltration and employing a multi-tenant phishing platform distributed through Telegram channels.
