Tenable & More Cyber Vendor’s Impacted by Third Party Salesforce Breach

Proofpoint, Tenable, CyberArk are other Third-Party vendors impacted by Salesforce Breach.

In an advisory released Tenable disclosed that it “was among the many organizations impacted” in the Salesloft Drift attacks, during which “an unauthorized user had access to a portion of some of our customers’ information stored in our Salesforce instance.”

Impacted data includes “subject lines and initial descriptions provided by our customers when opening a Tenable support case” as well as standard contact information such as name, business email address, phone number and location reference.

Tenable products and data stored in the vendor’s products, were not affected, the company said. CRN has reached out to Tenable for further comment.

Tenable stated that standard business contact information, such as customer names, email addresses, phone numbers and location details, was also accessed. At this point, the company stated there is no evidence that this information has been misused.

The information accessed by the unauthorized party was limited to data within Tenable’s Salesforce environment. This included:

  • Commonly available business contact information, such as customer names, business email addresses, and phone numbers.
  • Regional and location references associated with customer accounts.
  • Subject lines and initial descriptions that customers provided when opening a support case.

Third party vendor’s prime target of cyber attack increase Enterprise Cyber Risk

Targeting vendors indicate how critical it is to maintain third-party risk and be cautious while managing security risks associated with these external partners, focal point of target and critical for any organization’s data security.

The Tenable and other vendors being targeted increase the responsibility of enterprise based Third-party cyber risk associated as vendors can be targets for cyberattacks.

If their security measures are weak, your company’s data could be compromised. Ensuring vendors have strong cybersecurity protocols is essential to protecting sensitive information.

Enterprise security posture indicate how third-party security is a set of practices that can identify these risks and protect your organization from security threats associated with any third-party entity.

Risks arising from third-party vendors, contractors and business partners who have access to your data and systems is more then critical.

Three more well-known cybersecurity vendors have joined the lengthy list of companies impacted in the recent breach of a third-party Salesforce application, with Proofpoint, Tenable and CyberArk disclosing they were affected in the widespread Salesloft Drift attacks.

CyberArk, a publicly traded identity security vendor that Palo Alto Networks has a deal to acquire for $25 billion.

In similar pattern an unauthorized actor accessed Proofpoint’s Salesforce tenant through the compromised Drift integration and viewed certain information stored in our Salesforce instance,” the company said.

Attack module

The attacks involved stolen authentication tokens for Salesloft-owned workflow automation app Drift, which threat actors have used to steal data from Salesforce CRM systems. It’s unclear how threat actors obtained the tokens.

As per researchers, breach at Tenable was not an isolated attack but is linked to a wider, sophisticated campaign that security experts have been tracking. This campaign specifically exploits a vulnerability in the integration between Salesforce and Salesloft Drift, a popular sales engagement platform.

Fake Govt & Banking Apps Spreading Android Droppers Evolved as Malware

Security Advisory:  

Cybersecurity researchers have discovered a major shift in how Android malware is being delivered. Dropper apps, which were earlier used mainly to distribute banking trojans.

The Malware’s being used to deliver simpler threats like SMS stealers and basic spyware as official government or banking apps, primarily targeting users in India, Southeast Asia, and some parts of Europe. 

ThreatFabric researchers warn of a shift in Android malware: dropper apps now deliver not just banking trojans, but also SMS stealers and spyware, mainly in Asia.

Vulnerability Details 

The recent surge in Android dropper apps introduces a critical security vulnerability affecting mobile users globally. These droppers are impersonating as banking apps, government services, or trading platforms,, bypass Google Play

Pilot Program by initially requesting minimal permissions to avoid detection, making them appear as legitimate applications.

Once installed, they fetch malicious payloads like spyware, SMS stealers, cryptocurrency miners, and banking trojans from remote servers. Attackers also exploit malvertising campaigns on social media to spread fake apps widely. This evolving tactic enables cybercriminals to switch payloads dynamically, making traditional security measures less effective and increasing the risk of data theft and device compromise.

Attack Flow 

Step Description 
1. Craft Attackers create malicious dropper apps disguised as government schemes, banking apps, or trading tools. These apps are designed to look harmless and request only minimal permissions initially. 
2. Send The droppers are distributed through third-party APK sites, malicious ads (e.g., Facebook), or fake update prompts, bypassing initial detection. 
3. Trigger The victim downloads and installs the dropper app, often believing it’s legitimate due to its official-looking design and branding. 
4. Execution When the user clicks “Update” or interacts with the app, the dropper fetches the real malicious payload (spyware, SMS stealer, or banking trojan) from a remote server. 
5. Exploit The installed malware requests high-risk permissions, such as SMS access or notification access, allowing attackers to steal data, track activities, or control the device remotely. 

Proof-of-Concept 

Once the user interacts, the dropper initiates an HTTPS request to a remote server

Why It’s Effective 

Dynamic Payload Delivery – Attackers hide the real malicious file inside a harmless-looking dropper app. The payload is only downloaded after user interaction, making it harder to detect. 

Permission Evasion – Droppers initially request minimal or safe permissions and only ask for high-risk permissions (like SMS or accessibility access) after installation, bypassing Google Play Protest’sProtects initial scans. 

Fake Update Screens – Many droppers display legitimate looking “Update Required” prompts to trick users into downloading malware, increasing their success rate. 

Recommendations: 

Download Apps Safely  

  • Install apps only from trusted sources like Google Play Store, Apple store etc. 
  • Avoid third-party APKs, unknown links, or apps promoted through social media ads. 

Check Permissions Carefully  

  • Do not grant unnecessary permissions like SMS, notifications, or accessibility dependent on the app services. 
  • Always review requested permissions before installing or updating an app. 

Keep Devices Secure  

  • Enable Google Play Protect and keep your Android security patches up to date. 
  • Use a reliable mobile security solution for real-time malware detection. 

Stay Alert and Aware  

  • Be aware of fake update prompts; apps, and malicious sites. 
  • Stay updated on the latest tactics used by Android malware 

Conclusion: 

  • Android droppers are evolving fast, making them more flexible and harder to detect, increasing risks for both individuals and organizations.
  • Droppers started as tools for advanced banking malware, but now they’re used to install all kinds of harmful apps and sneak past local security.  
  • It is always recommended to stay vigilant, keep your phone and software updated from the original source  and avoid unverified apps installation to minimize the risk of infection.
