What is Slack?

Slack is known as a company communication tool that can facilitate collaboration between people within a company. Its simplicity of use, real-time capabilities, and relatively lower cost have made it an attractive option for businesses of all sizes to use. 

However, Slack faces increasing competition and pricing pressure as other companies launch similar services, making it important to understand the security challenges you may face if your business decides to adopt Slack.

Is Slack Secure?

Slack security worries have lingered since the platform’s security incident in 2015. Hackers gained access to Twitter’s internal systems through the firm’s Slack account in early 2015, where the attacker discovered “Twitter credentials” that “allowed him access to the corporate servers.” To fix the issue, Twitter had to be briefly taken down. In June 2021, hackers utilized Slack to dupe an EA Games employee by obtaining a login token, which they then exploited to steal data.

Slack continues to be a popular target for hackers who utilize a mix of social engineering and traditional malware to get access to user data. Here’s everything you need to know about Slack security and how to keep your critical data safe.

Slack Security

With private messages, groups, and channels, Slack enables end-to-end encryption for all users. While this is a positive move, firms must also assess their own security procedures to ensure that staff has the knowledge and skills to successfully utilize these security measures. Furthermore, conversations between Slack’s servers and users may be intercepted, posing an additional degree of danger.

Clients can manage users and groups, simplify authentication, and provide roles and permissions using Slack. The security elements of the platform are grouped into three categories:

  • Management of user identities and devices
  • Data security
  • Information management

Risks of Using Slack

Slack has proven to be an extremely popular tool for businesses. The company is aware of the threats that are coming from competitors and hackers, but not necessarily from the users themselves. It is important to consider how your business would cope if one of your channels got hacked by a competitor or an outsider. Here are some risks you need to know before using Slack: 

Vulnerabilities of Known and Unknown Systems

 Slack has a weakness in its code, but Its security risks come from user error. That’s the case with the proper on-boarding and off-boarding of Slack user accounts for both internal employees and external guests. If long-term data is left in the workspace after affiliations with the company have ended, the users may retain access to confidential or sensitive information. 

This is a risk for any tool that has an employee directory. However, the more use your team has of Slack, the higher the challenge becomes to keep their information up-to-date and secure. In addition, for guest users (non-employees), you have to manage their user accounts on your company’s Slack, which can be time-consuming with potential risks.

Open Communities and Phishing attacks

Slack’s ‘open communities’ feature allows large groups of people to connect with ease. Channels may be made with anybody, and all a user needs is a username to verify the identity of the person with whom they’re chatting.

As a consequence, Slack has grown into a medium where users must be aware of phishing attacks and spam messages, similar to email. Users believe that since Slack is invite-only, their workplace is secure, however, this is not always the case. One phishing incident to note includes a group of hackers who used a fake ‘Slackbot account to carry out a phishing effort that led users to a fake website where their financial information was taken.

Insider Threat

There’s a lot of mystery around which Slack team members have access to user data and when they may do so. Slack claims to have technological, audit, and policy measures in place to prevent unauthorized access, but they also admit that it did not design an app to prevent workers from accessing information without permission.


Slack does not have built-in message monitoring. Because the bulk of security threats are supplied via message content in the form of infected links, attachments, and photos, this is a serious security weakness. Businesses and individuals that use Slack must be aware of security concerns and take steps to reduce them. It’s also not a good idea to send sensitive information through Slack. 

Slack is a highly important and efficient communication channel for businesses, despite the security risks it may have. Businesses will continue to use Slack despite security concerns, just as they will continue to use email. All firms should think about Slack’s security, as well as the safeguards they may take to protect the safety of their employees, sensitive data, and financial information sent through Slack.
