Multiple cloud accounts have been compromised through passkey-themed social engineering campaigns since May 2026. Attackers impersonate IT helpdesk staff via phone calls or SMS, directing victims to phishing sites that mimic Microsoft sign-in pages. After obtaining credentials through adversary-in-the-middle or device code authentication flows, attackers establish persistence by adding unauthorized MFA methods. They then conduct extensive reconnaissance using Microsoft Graph API to map users, groups, permissions, and resources. The intrusion culminates in high-volume data collection from SharePoint, OneDrive, and Exchange using automated tools, with exfiltration occurring over hours or days at controlled rates to avoid detection.

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.

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.

European governments are transitioning from encrypted messaging applications like Signal and WhatsApp to sovereign Matrix-based solutions. This shift follows successful phishing campaigns, primarily attributed to Russian intelligence services, exploiting Signal's linked devices feature to gain persistent access to political communications. While Signal was initially recommended for external communications, scope creep led to its widespread use for sensitive statecraft discussions. Matrix-based systems offer advantages including federated architecture, government-controlled identity platforms, and customizable data retention policies. However, these homegrown solutions introduce new security vulnerabilities and implementation challenges. The walled-garden nature of current sovereign systems limits their utility for international diplomacy, suggesting Signal will continue to be used for communications with external parties despite the security concerns.

In early May 2026, Instructure confirmed a breach affecting its Canvas learning platform after detecting unauthorized activity on May 1. ShinyHunters exploited the Free-For-Teacher account program, compromising the Canvas platform directly and exposing names, email addresses, student IDs, and private messages. The exposure window ran from April 30 to May 7, 2026. ShinyHunters claims 3.6 TB of data covering approximately 275 million users across 9,000 schools globally, including institutions in the US, Australia, and EU. This represents ShinyHunters' second attack against Instructure in eight months. Instructure shut down the Free-For-Teacher program permanently, rotated API keys and privileged credentials, and engaged forensic investigators. The stolen data enables personalized phishing campaigns targeting students and faculty, with attackers potentially having write access sufficient to deface login pages at multiple institutions.

This article explores the misuse of QR codes in phishing attacks, focusing on three key areas: QR codes with URL shorteners concealing malicious destinations, in-app deep links used to steal credentials and control victims' apps, and QR codes bypassing app store security via direct malicious app downloads. The research reveals an average of 11,000 daily detections of malicious QR codes, with financial services being the most targeted industry. Attackers are leveraging QR code shorteners, in-app deep links, and direct downloads to evade security controls and exploit users' trust in QR codes. The article highlights specific attack scenarios, including account takeovers through messaging apps and distribution of suspicious gambling apps.

An AWS environment was targeted in a sophisticated attack, with the threat actor gaining administrative privileges in under 10 minutes. The operation showed signs of leveraging large language models for automation and decision-making. Initial access was obtained through credentials found in public S3 buckets, followed by rapid privilege escalation via Lambda function code injection. The attacker moved laterally across 19 AWS principals, abused Amazon Bedrock for LLMjacking, and launched GPU instances for potential model training. The attack involved extensive reconnaissance, data exfiltration, and attempts to establish persistence. Notable techniques included IP rotation, role chaining, and the use of AI-generated code.

Threat actors associated with ShinyHunters-branded extortion operations are expanding their tactics, targeting cloud-based SaaS applications for data theft and extortion. The attackers use sophisticated voice phishing and credential harvesting to gain initial access, then exfiltrate sensitive data from various platforms. They employ aggressive extortion tactics, including harassment and DDoS attacks. The activity involves multiple threat clusters (UNC6661, UNC6671, UNC6240) and targets a growing number of cloud platforms. The attackers leverage social engineering to bypass MFA and use tools like ToogleBox Recall to cover their tracks. This activity highlights the effectiveness of social engineering and the importance of phishing-resistant MFA methods.

The Jingle Thief campaign, conducted by financially motivated threat actors from Morocco, targets global enterprises in retail and consumer services sectors to execute gift card fraud. Using phishing and smishing tactics, the attackers gain access to Microsoft 365 environments, exploiting cloud services for reconnaissance, lateral movement, and persistence. They focus on compromising gift card issuance systems, leveraging internal documentation and communication channels. The campaign demonstrates sophisticated techniques, including tailored phishing, internal email manipulation, and device registration abuse. The attackers maintain long-term access, sometimes over a year, making detection challenging. Their activities often align with holiday periods to maximize impact.
