Summary
WK Kellogg suffered a data breach in December 2024, impacting employee data due to vulnerabilities in Cleo, a third-party file transfer software. The Clop ransomware group is suspected to be behind the attack, and Kellogg’s is offering affected individuals identity theft protection. This incident highlights the increasing risk of third-party software vulnerabilities.

** Main Story**
Okay, so you heard about the WK Kellogg data breach, right? It’s a stark reminder that even the biggest companies aren’t immune to cyberattacks. And this one really stings because it involved sensitive employee data. I mean, who wants their Social Security number floating around out there?
Apparently, back in December 2024, Kellogg’s got hit with a data breach that compromised employee info. The culprit? A vulnerability in file transfer software made by a third-party vendor called Cleo. It’s a classic case of supply chain risk, something we’re seeing more and more of these days. Honestly, it keeps me up at night thinking about all the vendors we rely on and how secure they really are.
The Breach: A Timeline
Let’s break down the timeline because, frankly, it’s a bit concerning:
- December 7, 2024: The bad guys get in by exploiting weaknesses in Cleo’s software.
- February 27, 2025: Kellogg’s figures out they’ve been breached – almost three months later! That’s a long time to be compromised.
- April 4, 2025: Affected employees finally get notified, and they get a year of identity theft protection.
Three months to discover you have been breached! I mean imagine that. You’d think detection times would be quicker, especially given all the security tools available these days. A long dwell time like that just gives the attackers more opportunity to cause damage.
The Cleo Connection and Clop’s Involvement
So, what was Cleo’s role in all this? Well, it turns out their Harmony, VLTrader, and LexiCom software had some pretty serious vulnerabilities. One of them, CVE-2024-50623, allowed anyone to upload and download files without permission. Another, CVE-2024-55956, let attackers run commands remotely, effectively giving them the keys to the kingdom.
Even though Cleo released a patch, it clearly didn’t do the trick, did it? Honestly, its never a good sign when the patch doesn’t fix the problem.
The prime suspect behind the attack is the Clop ransomware group. These guys are notorious for targeting file transfer tools. Remember the MOVEit Transfer hack in 2023? Or the Accellion fiasco in 2021? It’s basically their MO: find a weakness, steal data, and then hold companies hostage for ransom. And in February 2025, Clop listed WK Kellogg on their dark web leak site, turning up the heat. It wasn’t a good look for anyone.
The Fallout: Impact and Response
What kind of data are we talking about? Employee names and Social Security numbers – the kind of stuff that can ruin lives. The full scope of the breach is still a bit hazy, but we know at least one person in Maine had their info stolen.
Kellogg’s offered affected individuals a year of identity theft protection, but is that really enough? It helps, sure, but it doesn’t undo the potential damage. It really highlights the need to make sure vendors are up to scratch security wise. Think about what due diligence procedures they have, regular security assessments and a good plan in case of a breach.
Lessons Learned and the Bigger Picture
This Kellogg’s breach is a wake-up call. It’s a reminder that:
- The cybersecurity landscape is constantly evolving. We need to stay ahead of the curve.
- Third-party risk is a HUGE deal. You’re only as strong as your weakest link.
- Zero-day exploits are scary. You can’t defend against what you don’t know, but you can have a plan in place to respond quickly.
It’s a tough situation, but it’s not hopeless. By prioritizing security throughout our supply chains and staying vigilant, we can minimize the risk of becoming the next Kellogg’s. It’s all about continuous improvement and being proactive, wouldn’t you agree? I mean, we can’t just sit back and wait to be attacked, can we?
Three months to discover the breach? Were they using carrier pigeons to monitor network traffic? Perhaps a better solution would be to hire a bloodhound! On a serious note, what’s the average detection time for breaches of this scale? Just curious.
That’s a great question! Industry averages vary, but for breaches of this scale, a lot of reports suggest the median dwell time is still around a month, which is still far too long. Early detection is key, and better tooling is essential! What detection strategies do you think are most effective?

Given the Clop ransomware group’s history of targeting file transfer tools, what proactive measures beyond patching can organizations implement to mitigate risks associated with vulnerabilities in these widely used systems?
That’s a crucial point about proactive measures. Beyond patching, I think robust access controls and network segmentation are key. Regular penetration testing specifically targeting file transfer systems can also reveal weaknesses before attackers do. What other non-patching strategies have you found effective in your experience?

The Clop group’s repeated targeting of file transfer tools underscores the need for organizations to diversify their security strategies, moving beyond solely perimeter-based defenses to incorporate robust internal monitoring and data loss prevention measures.
That’s a really important point about diversifying security strategies! I agree that internal monitoring and data loss prevention are crucial layers of defense, especially given the Clop group’s focus. What specific internal monitoring techniques have you found most effective in detecting suspicious file transfer activity?

So, Kellogg’s offered identity theft protection. A year? Really? Seems like a lifetime subscription to a therapist might be more useful after having your SSN leaked. What’s the going rate for emotional distress these days? Asking for a friend… whose data might also be compromised someday.
That’s a hilarious, and sadly, very valid point! A lifetime subscription to a therapist might indeed be more fitting! It really highlights how the impact of these breaches goes far beyond just financial risk. The emotional toll is significant and often overlooked. Perhaps companies should start factoring that into their response plans.

The Clop group’s pattern of targeting file transfer tools highlights the need for more stringent vendor risk management. Regular security audits and penetration testing of third-party software should be a mandatory component of any organization’s security posture. What specific contractual clauses can ensure vendor accountability in the event of a breach?
