Learning from corporate espionage case

A new lawsuit in the HR services industry accuses HCM provider Deel of planting a rogue employee in competitor Rippling’s Dublin office. By exploiting proprietary company information within Slack, the mole accessed trade secrets, sales leads and other intellectual property over several months, according to the suit. Rippling then exposed the scheme using a carefully orchestrated “honeypot” trap within Slack, the suit says.

The implications are clear: Communication tools like Slack and Microsoft Teams, though indispensable for collaboration, are attractive targets for insider threats and cyberattacks. Without robust security protocols, organizations risk exposing their sensitive data to catastrophic breaches.

Slack has revolutionized workplace communication. Nearly half of Fortune 500 companies rely on Slack to manage their daily operations, thanks to its convenience and efficiency.

However, centralized data repositories and the extensibility of its open API also make it highly vulnerable to exploitation by bad actors. Every Slack workspace contains valuable assets, including intellectual property, financial documents and strategic discussions, making it a prime target for insider threats and external breaches.

The Rippling case demonstrates just how easily Slack’s convenience can be turned into a liability. Across industries, these vulnerabilities demand vigilance and a commitment to proactive security measures, including monitoring internal messaging alongside email. These measures help security professionals ensure that data is being properly shared to minimize risk exposure.

Lessons from corporate espionage

Rippling’s honeypot trap reveals how easily communication platforms like Slack can be weaponized. According to the lawsuit, the company identified suspicious activity after its employee planted at Deel began searching Slack for mentions of competitors, sensitive payment information and confidential sales pitches. The lawsuit reports that Deel used this information until legal action was taken.

Other organizations have suffered severe consequences from insider threats and cyberattacks. The most famous example is Disney’s Slack data breach: The hacktivist group NullBulge infiltrated Disney’s Slack system, exfiltrating more than a terabyte of data, including unreleased projects and employee information. NullBulge claimed that an insider facilitated the breach by providing access to the company’s Slack channels, which led to Disney transitioning away from Slack.

These examples illustrate the far-reaching consequences of communication platform exploitation, whether through employee misconduct or external attacks. At the same time, security professionals can’t bury their heads in the sand—it’s incumbent on them to investigate all employee communications for various reasons, such as a data breach, insider threat event, HR complaint or a legal violation.

Common vulnerabilities of workplace collaboration tools

To understand the potential risks, organizations need to evaluate key vulnerabilities within Slack, Teams and similar environments. These are:

1. Insufficient or misconfigured access controls. Misconfigured user permissions and inadequate oversight of guest access leave critical channels exposed to unauthorized individuals.
2. Third-party integrations. Integrating third-party apps can streamline workflows, but it also expands the attack surface by introducing new entry points for cyberattacks.
3. Endpoint security gaps. Employees’ use of personal devices or unsecured connections can compromise Slack ecosystems, allowing attackers to gain entry.
4. Lack of data retention and auditing policies. Without clear policies in place, malicious activities often go unnoticed in the constant flow of communication on Slack.
5. Weak credential management. Practices such as reusing passwords and failing to use multi-factor authentication (MFA) heighten the risk of account takeovers that would expose sensitive information.

Solutions to protect these environments

Organizations seeking to mitigate these risks require advanced, highly adaptive cybersecurity solutions, including:

1. Enhanced threat detection. This includes continuous monitoring of Slack for abnormal activities such as unauthorized downloads or attempts to breach private channels.
2. Data loss prevention (DLP). DLP policies empower businesses to secure sensitive data, ensuring it is only accessed or shared on authorized terms.
3. Integration security. This strengthens the security of third-party integrations by closely monitoring API interactions and detecting potential exploits.
4. Advanced malware protection. Blocking malicious links, malware and phishing attempts within Slack conversations helps protect data before attackers can act.
5. Granular compliance management. This will simplify compliance with regulatory standards such as GDPR or HIPAA by providing tools for auditing channel activity and managing access controls effectively.
6. Backup and recovery solutions. Whether addressing accidental deletions or targeted attacks, organizations need a seamless recovery of lost data to minimize business disruption.

Preparing for the future of workplace communication

The Rippling-Deel case highlights how seemingly secure communication platforms can expose critical weaknesses when they are not proactively safeguarded. Forward-thinking organizations must learn from these lessons to prioritize the security of tools central to their operations.

Key takeaways

• Rippling, a fast-growing HR software company, accused its competitor Deel of corporate espionage involving long-term IP theft within Rippling’s Slack channels.
• This case is a wake-up call for business leaders across industries. The Rippling lawsuit against Deel is a stark reminder of the vulnerabilities hidden within modern communication tools.
• It underscores the pressing need for effective security measures to safeguard sensitive workplace communication platforms.
