Sophisticated Social Engineering Campaign Targets Salesforce via Malicious Apps
An advanced cyber threat group known as UNC6040 has managed to breach several corporate Salesforce environments using a cunning blend of social engineering and technical manipulation. Operating under the radar, the attackers didn’t exploit bugs in Salesforce itself. Instead, they turned employees into unwitting accomplices through targeted voice phishingâbetter known as vishing. By impersonating IT support staff, they convinced victims to approve a malicious connected app that resembled Salesforceâs legitimate Data Loader tool. Once installed, this rogue application allowed the threat actors to siphon off vast amounts of confidential business data.
The malicious campaign, uncovered by Googleâs Threat Intelligence Group (GTIG), centered on abuse of Salesforceâs connected apps functionality. Victims were led through the process of authorizing what appeared to be a standard tool, but in reality, it was linked to infrastructure controlled by UNC6040. With access granted, the attackers used the app to query and export sensitive corporate information at scale. Evidence further suggests that attackers operated from anonymized VPN services like Mullvad and hosted Okta phishing panels to harvest credentials and bypass security mechanisms such as MFA.
While traditional endpoint defenses and cloud infrastructure remained uncompromised, the human element proved to be the weakest link. Attackers employed real-time manipulation tactics during calls to obtain login credentials and authentication codes, enabling them to implant and legitimize their rogue app access. In some cases, the malicious apps were deceptively namedâlike âMy Ticket Portalââto align with the pretext used during the phishing call, increasing their success rate. Incident responders found that data exfiltration began almost immediately after the attackers gained access, with some organizations only discovering the breach months later during extortion attempts linked to other groups like ShinyHunters.
Security professionals now emphasize the need for stronger governance of third-party app permissions and stricter cloud access configurations. This breach highlights that SaaS security isnât just about the provider’s defenses, but also how organizations manage, monitor, and educate their workforce against ever-evolving social engineering strategies. With the line between trusted apps and malicious ones becoming increasingly blurred, proactive defense strategies and robust user training have never been more essential.
What Undercode Say:
This UNC6040 campaign exemplifies a paradigm shift in cyberattack methodologies, where direct exploitation of cloud platform code takes a backseat to manipulating the weakest layerâhumans. Instead of launching brute-force attacks or discovering zero-day vulnerabilities, this group leverages soft skills like persuasion, impersonation, and timing. The use of voice phishing indicates a move toward more analog, low-tech vectors that bypass even the most sophisticated digital defenses.
Salesforceâs connected apps are not inherently insecure. However, the campaign cleverly repurposes the platformâs flexibility and user configurability against itself. By mimicking Salesforceâs own Data Loader, attackers turned a legitimate tool into a Trojan horse. This raises the importance of tightly controlling what apps are authorized in any enterprise SaaS ecosystem.
From an operational security perspective, the use of VPNs like Mullvad and phishing panels shows UNC6040âs capability to anonymize operations and delay detection. The attackersâ agility in harvesting real-time MFA codes reflects a disturbing rise in hybrid attack strategies that blur the line between technical and social engineering.
Additionally, the presence of a delayed extortion phase indicates that stolen data isnât always weaponized immediately. It suggests a layered criminal operation where data exfiltration is passed along to monetization groups like ShinyHunters. That collaboration between separate threat actors shows increasing professionalism and modularity within cybercriminal circles.
The breach is also an indictment of the current state of user training and incident response. If attackers can walk an employee through approving a malicious app over the phone, then the organizationâs onboarding, security awareness, and app governance protocols are either lacking or unenforced.
Security recommendations stemming from this incidentâsuch as IP-based access control, continuous activity monitoring, and least-privilege app permissionsâare vital but often difficult to implement without friction. Yet, the consequences of neglect are becoming increasingly expensive.
Organizations must adapt by implementing behavioral analytics and automated anomaly detection for app authorizations. More importantly, companies should adopt a ânever trust, always verifyâ mindset, especially for internal IT interactions. Voice authentication or callbacks for IT support requests can thwart real-time social engineering efforts.
This case reaffirms the growing trend of abusing cloud platforms through indirect manipulation rather than code-level attacks. Cloud environments offer immense power but also complexityâand this complexity can be weaponized. The lesson is clear: in the era of SaaS, the user is the new perimeter, and securing that perimeter requires both technological controls and human resilience.
Fact Checker Results:
â
Was the breach caused by a software vulnerability? No â
â
Was social engineering the primary method of compromise? Yes â
â
Was sensitive corporate data exfiltrated during the attack? Yes â
Prediction:
As more companies adopt SaaS platforms like Salesforce, threat actors will increasingly target connected apps and user trust rather than platform vulnerabilities. Expect to see a rise in malicious app authorizations and tailored phishing campaigns that align with legitimate workflows. Enterprises that fail to educate users and monitor third-party integrations in real time will remain prime targets for campaigns like UNC6040. đŠď¸đđ
