In recent months, a financially motivated cybercriminal group known as UNC6040 has been using sophisticated vishing attacks to exploit vulnerable organizations, particularly those using Salesforce platforms. This method, which relies on social engineering and voice-based phishing, has led to the theft of vast amounts of data. UNC6040’s campaign highlights a major gap in cybersecurity defenses—many companies still fail to recognize the dangers posed by social engineering tactics like vishing.
the Original
Google’s threat intelligence group recently uncovered a malicious campaign carried out by UNC6040, a financially motivated threat group targeting organizations that use Salesforce. The attackers pose as IT support staff and use voice phishing (vishing) to manipulate employees into granting them access to their company’s Salesforce environment. Once access is granted, UNC6040 installs a malicious version of Salesforce’s Data Loader app. This modified app allows the attackers to access, query, and steal sensitive company data from Salesforce platforms without triggering any alarms.
This type of social engineering attack bypasses traditional security measures, relying solely on human error rather than technical vulnerabilities. Vishing scams like these can involve phone calls impersonating a variety of trusted entities, from CISA staff to bank employees, further tricking employees into compromising their organizations’ security. After initial access, the attackers often exfiltrate data and may wait months before demanding ransom, making it harder for companies to immediately detect the breach.
Moreover, the attackers often move laterally across the network to other platforms such as Okta and Microsoft365. They then attempt extortion using the stolen data, sometimes claiming affiliation with high-profile hacking groups like ShinyHunters to increase pressure on the victims. Despite the simplicity of the attack method, it has proven to be remarkably effective, with many organizations unaware of the risks posed by malicious versions of legitimate apps like Salesforce’s Data Loader.
What Undercode Say: Analyzing the Vishing Threat to Salesforce Platforms
Undercode has followed and analyzed the growing trend of vishing-based attacks targeting SaaS (Software-as-a-Service) platforms like Salesforce. Unlike traditional cyberattacks that exploit software vulnerabilities, UNC6040’s tactics depend entirely on social manipulation. This shift emphasizes the increasing need for employee education and awareness regarding cybersecurity best practices.
One critical vulnerability in many organizations’ cybersecurity strategies is the over-reliance on automated or technical defenses without considering the human element. While tools like firewalls and MFA (Multi-Factor Authentication) offer strong protection, they can only go so far when employees are unaware of the risks posed by seemingly benign interactions. In the case of Salesforce, many employees cannot tell the difference between a legitimate IT support call and a malicious one. This makes them prime targets for attackers.
Moreover, the growing complexity of SaaS platforms themselves presents additional opportunities for attackers. Platforms like Salesforce are not only highly integrated but also contain various configuration settings that, when mismanaged, can leave organizations vulnerable to unauthorized access. Attackers can exploit these misconfigurations to steal data or install malicious applications, as seen in the case of UNC6040. Yoni Shohet, CEO of Valence Security, points out that organizations must take responsibility for securing their SaaS environments and not solely rely on the provider’s security measures.
The delay between initial data theft and extortion attempts is another worrying trend. This long latency can give attackers more time to move undetected within the compromised networks, exfiltrate more data, and even target other services. As companies continue to focus on immediate breach detection, they may overlook the need for long-term surveillance and response strategies to prevent these stealthier, more insidious attacks.
In response to this growing threat, Salesforce and Google have recommended several protective measures, including restricting access to Data Loader and other critical tools, implementing least-privilege access policies, and enabling multi-factor authentication. However, these steps must be paired with a strong focus on employee education and ongoing monitoring to reduce the risk of social engineering attacks.
Fact Checker Results ✅
Vishing remains a top method for data theft: The attack method used by UNC6040, vishing, has been proven effective in stealing sensitive information from organizations. This is a growing concern that cybersecurity experts warn about.
Social engineering outpaces traditional cyberattacks: Attackers are increasingly bypassing technical vulnerabilities and instead manipulating individuals into compromising security. This trend is on the rise.
MFA and least-privilege access are critical defenses: Experts agree that multi-factor authentication and restricting access to essential tools are key defenses against these types of attacks.
Prediction 📊
As more organizations migrate to cloud-based platforms like Salesforce, the risk of vishing and other social engineering attacks will continue to grow. Attackers are becoming more adept at manipulating individuals into unknowingly granting them access to sensitive systems. This will likely lead to an increase in data breaches, especially as attackers refine their tactics. Companies will need to invest more in educating employees about social engineering and enhancing their cybersecurity training to prevent these types of scams from succeeding. Moreover, with the growing complexity of SaaS platforms, businesses will have to focus on both technical defenses and human factors to better protect their data from malicious actors.
