How to Work Together Without Endangering Your Safety Using Slack

Lax Security Procedures

The programme known as Slack is quite popular. In 2020, it turned out to be an absolute need for many businesses to be able to conduct remote work, and it will continue to play an important role in people's daily lives in the workplace for many years to come.

However, the fact that it is a beneficial software for business does not imply that it is problem-free. This software, like many others, is susceptible to being hacked, which may result in the theft of data and mayhem.

In order for businesses to get the most of Slack, they need to ask themselves the following questions: Is it Safe to Use Slack?

We'll go through the problems that are built into the software as well as some solutions that your firm may use to make Slack more secure. Slack Security is a goal that can be attained with our solution.

Concerns About Lax Safety Measures

Slack does not provide any security precautions by default for its users. That implies that anything you provide, including files, information, and data about your firm, is vulnerable to being hacked.

There is a widespread misconception that everything that is spoken on Slack—given that the platform is only accessible by invitation—is subject to confidentiality restrictions.


An employee on any plan has the ability to generate an external link, which transforms a file that is attached to an organisation into a URL that is accessible to the public. Anyone who is already a member of Slack has the ability to establish and update user groups, add applications and integrations, invite new members, and even invite a multi-channel visitor to a private channel.

It also implies that the potential for anarchy is considerable since anybody can establish groups, add applications, and invite members.

Slack Data Security Companies share anything on Slack, including files, budgeting spreadsheets, corporate announcements, and confidential papers. Slack is designed to protect sensitive information. They post hilarious GIFs in addition to absolutely everything else:

However, the capacity to share may result in a number of undesirable results, including the following:

The transmission of confidential information outside of the company with the click of a mouse, either accidentally or on purpose.

Members from the outside of a corporation, who are able to quickly and simply join its channel, have unrestricted access to the complete repository of information.

Any data or information that is shared on Slack may be quickly distributed to other users. This may be done on purpose or inadvertently; many users assume Slack to be an internal tool, but they forget that external partners may also have joined a channel in which they are communicating.


Users of Slack have the potential to unknowingly spread malware or links to websites containing dangerous content since the platform offers no safeguards against such activity. And since most workers trust the platform, it is possible for anybody working for your organisation to inadvertently download malware or click on a link that leads to a dangerous website.


Joining a channel on Slack is a very simple process. Any user, regardless of their permission level, may invite other people to join, regardless of whether they work for the firm or not. The approval procedure is often lax and its requirements are very loosely followed.

Because of the rapid increase in the number of people using Slack, unknown users are more inclined to believe what they see and to accept permissions in bulk.


Email is often the medium via which the first hacked account is discovered. In order to avoid being discovered, subsequent "east-west" compromises will often avoid communicating over email. As more businesses migrate their internal communication to Slack, cybercriminals will inevitably follow suit.

Best Practices for Lax Internet Security

The aforementioned information may seem to be overwhelming, but there are methods to safeguard your firm.

The solution may be explained as follows:

Before being downloaded, each file is put into a sandbox. A file that has been found to contain zero-day malware or ransomware is placed in quarantine by Avanan, which then conducts threat extraction and notifies the user. The user then has the choice to ask for the file to be restored.

PCI, HIPAA, FERPA, PII, and other sensitive information may all be detected and stopped by using DLP security technologies. When it is required, Avanan will append the suffix -classified to the end of any messages or files that are considered to be secret. It is up to the flexible workflows to decide if the material should be quarantined, whether the user should be notified, or whether the file should be encrypted using IRM.

The anomaly engine keeps a close eye on all logins and activities in Slack, looking for any unusual behaviour. In order to prevent sensitive data, malware files, and phishing URLs from being shared further, Avanan notifies the Slack administrator, disables the hacked account, and notifies the accounts that have been impacted.
