Slack's free plan limits users to viewing and searching only the most recent 10,000 messages. Users can add emoji buttons to their messages, on which other users can then click to express their reactions to messages. Content, including files, conversations, and people, is all searchable within Slack. Slack offers many IRC-style features, including persistent chat rooms (channels) organized by topic, private groups, and direct messaging. After 3 PM, most of the core features became operational, except for push notifications, email, and third-party integrations including Google Calendar and Outlook Calendar. From 10 AM ET until 3 PM ET users could not log-in, send or receive messages, place or answer calls, and use Slack connections. On January 4, 2021, Slack suffered a large outage which lasted several hours. In response to the attacks, Slack added two-factor authentication to its service. In March 2015, Slack announced it had been hacked over four days in February 2015, and that some data associated with user accounts had been compromised, including email addresses, usernames, hashed passwords, phone numbers, and Skype IDs. On January 1, 2021, Slack and Salesforce announced an agreement for Salesforce to acquire Slack for a value of approximately $27.7 billion. In June 2019, Slack went public through a direct public offering to reach a market value of US$19.5 billion. Slack was previously compatible with non-proprietary Internet Relay Chat (IRC) and XMPP messaging protocols, but the company closed the corresponding gateways in May 2018. Īccording to Butterfield, "Slack" is an acronym standing for "Searchable Log of All Conversation and Knowledge," which he chose in 2012 to replace the previous codename, "linefeed." Slack launched to the public in August 2013. Thankfully, that wasn't the case this time.Slack began as an internal tool for Stewart Butterfield's company Tiny Speck during the development of Glitch, an online game. Slack now does appear to be offering higher payouts for significant exploits such as this - an important move, as a less noble researcher could have sold this "critical" vulnerability to a malicious buyer. However, as Mashable explains, many members of the security community feel that this wasn't enough.Ī spokesperson for Slack responded to these comments, explaining: "We deeply value the contributions of the security and developer communities, and we will continue to review our payout scale to ensure that we are recognizing their work and creating value for our customers." The spokesperson added that an initial fix for this exploit was implemented in February. For his efforts, the researcher was awarded a fee of $1,750. An independent security researcher notified Slack via bug bounty platform HackerOne earlier this year. The vulnerability wasn't identified by Slack's security team, however. It's clear that a huge amount of sensitive information could have been maliciously captured using the security exploit. What's more, it was possible to make the attack "wormable," allowing it to be passed on from one account to a whole group of users, thereby compromising an entire Slack team.

In the wrong hands, the exploit would have allowed remote code execution, making it possible for a hacker to access passwords, internal network access, and files. A security vulnerability in the service's desktop app, which is now fixed, could have caused major problems.

In the current age of remote working, more people are relying on team collaboration tools and Slack is one of the top services in the category. But members of the security community are arguing that the fee paid by Slack wasn't nearly enough. A security researcher identified the bug, posted it through a bug bounty platform, and was compensated for his efforts. In context: Slack has fixed a "critical" vulnerability in its desktop app that could have posed a significant threat for users of the messaging service.
