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.
A phishing campaign is impersonating LastPass by sending scam emails with alarming subjects like 'We Have Been Hacked' to trick users into clicking malicious links. These links lead to fake websites hosted on domains such as lastpassdesktop.com, designed to steal credentials and secret keys, potentially compromising users' password vaults. LastPass has confirmed it has not been breached and is actively working with partners like Cloudflare to take down these fraudulent domains and warn users. Similar phishing attacks have targeted other password managers, increasing the risk to users relying on these services. The campaign leverages social engineering tactics to create urgency and exploit trust in the LastPass brand. No direct system vulnerabilities are exploited, but the threat targets user credentials through deception. European organizations using LastPass or similar password managers are at risk of credential theft if users fall for these scams. Mitigation requires user education, domain blocking, and enhanced email filtering to detect and prevent phishing attempts.
