Nikkei’s Slack Attack: When One Employee’s Virus Spills 17,000 Secrets!
Nikkei Inc. suffered a data breach exposing 17,368 Slack accounts due to a single compromised account. The Japanese media giant, owner of the Financial Times, is no stranger to cyberattacks, having lost $29 million in a previous email scam. So much for “slacking” on security!

Hot Take:
Looks like Nikkei’s Slack workspace just got a little too “social,” as unwanted guests crashed the chat and took home some party favors. With over 17,000 employee accounts exposed, it seems like the only thing tighter than their chatrooms is their belt-tightening response to yet another cyber mishap. Maybe it’s time for Nikkei to invest in some digital locks and throw away the keys, eh?
Key Points:
- Nikkei Inc. disclosed a data breach affecting over 17,000 employee Slack accounts.
- The breach occurred due to a virus on an employee’s personal computer.
- Exposed information includes names, email addresses, and chat histories.
- No journalist source data was leaked, says Nikkei.
- This isn’t Nikkei’s first rodeo with cyberattacks; they’ve faced BEC and ransomware hits before.
