A new phishing campaign impersonating LastPass is circulating today, October 13, 2025, aiming to deceive users into downloading malicious desktop software. Emails purporting to come from “[email protected]” or “[email protected]” carry the alarming subject line “We Have Been Hacked – Update Your LastPass Desktop App to Maintain Vault Security.”
In reality, LastPass has not been compromised; threat actors are leveraging fear and urgency to lure victims into installing malware.
The fraudulent messages mimic official LastPass communications in tone and formatting, warning recipients that their vaults are at risk unless they install an urgent “desktop app update.”
Embedded in the email body is a link that appears to point to a legitimate LastPass download page. In reality, clicking the link directs users to one of two malicious domains: “lastpassdesktop.com” (serving IP 172.67.147.36) or “lastpassgazette.blog” (serving IP 84.32.84.32).
The attackers have also pre-registered “lastpassdesktop.app” (serving IP 172.67.219.2), indicating plans for additional phases of the campaign.
These domains are hosted on NICENIC, a known bulletproof hosting provider favored by cybercriminals for resisting takedown requests.
The campaign’s timing over a U.S. holiday weekend suggests that the perpetrators hope reduced staffing at security teams will delay detection and removal of their phishing infrastructure.
Threat Actor Tactics and Technical Indicators
Social engineering remains the cornerstone of this scheme. By fabricating a security breach, the attackers exploit the innate human response to panic and urgency.
Recipients are prompted to bypass caution and execute the malicious installer, which can deploy keyloggers, backdoors, or other malware designed to harvest sensitive credentials.
Key indicators of compromise include:
- Sender Addresses: Legitimate LastPass mail servers never use “@lastpasspulse.blog” or “@lastpassgazette.blog.”
- Domain Registrations: The domains are recent registrations with minimal WHOIS information, lacking affiliation with LastPass.
- Hosting Provider: Use of NICENIC bulletproof hosting, notorious for sheltering illicit operations.
- Timing: Launch during a holiday period to exploit potential delays in monitoring and incident response.
Analysts have noted that while the phishing sites superficially resemble LastPass’s official portal, they lack proper TLS certificates signed by recognized authorities.
Visitors are greeted with generic warnings from Cloudflare alerting them to phishing content, but unsuspecting users may ignore or override these warnings if they feel pressured by the email.
Recommended Precautions
LastPass customers should remain vigilant and remember that no one at LastPass will ever ask for your master password or prompt you to download unverified updates. If you receive a suspicious email:
- Do not click any links or download attachments.
- Verify the sender’s domain and check for spelling or formatting errors.
- Hover over links to confirm the actual destination domain.
- Report the email to [email protected] for further analysis.
Meanwhile, LastPass is actively coordinating with domain registrars, hosting providers, and law enforcement to facilitate takedowns. At the time of publication, Cloudflare has already inserted warning pages in front of the malicious sites to deter victims.
Users are encouraged to review and enable multi-factor authentication on their LastPass accounts for an additional security layer. Regularly updating antivirus definitions and employing endpoint protection can also help detect and block malware installations.
By staying informed of the latest phishing tactics and exercising cautious scrutiny of unexpected security alerts, LastPass users can protect their credentials and maintain the integrity of their password vaults.
