In August 2023, Clorox says, someone phoned its outsourced Cognizant help desk pretending to be two different employees. Agents reset their passwords and MFA, phone number for SMS codes included, without checking who was calling. Operations were disrupted for weeks. Clorox wants $380 million from Cognizant. That's a claim, not a proven loss, and a March 25, 2026 ruling let three of its four claims go ahead.

Clorox filed the complaint on July 22, 2025, in Alameda County's branch of the Superior Court of California. It quotes from recordings of the service-desk calls themselves. Everything below comes from that complaint. It's Clorox's side of the story, not something a court has found.
| Call and identity claimed | What the caller asked for | What the agent did |
|---|---|---|
| 1 (August 11, 2023), as Employee 1 | A password, saying they could not connect; then help because their Microsoft MFA was not working | Read out a new password and reset Microsoft MFA, with no identity checks |
| 2 (same day), as Employee 1 | Another MFA fix | Reset Microsoft MFA a second time |
| 3 (about 20 minutes later), as Employee 1 | Another credential reset | Reset the Okta credential again |
| During the Employee 1 calls | A new phone number for SMS-based MFA | Changed the number, handing the caller the second factor |
| 4 and 5, as Employee 2, a member of Clorox's IT security team | Password and MFA resets | Reset the password and both the Okta and Microsoft MFA; one agent offered to reset "two MFA applications" |
The excerpts are striking for how little effort the caller needed. No emergency, no dropping an executive's name. Just an everyday story about being locked out. On the first call the agent replied, "So let me provide the password to you ok?" and read out a password beginning with "Welcome."
Nobody on the desk asked why one employee kept needing resets so close together, according to the complaint. And the agent handling the Employee 1 calls never sent the confirmation emails to the employee and their manager that Clorox's procedure called for.
Help-desk vishing is a con where someone rings the IT support line, claims to be an employee, and talks the agent into resetting their credentials or MFA. Here's how the Clorox intrusion played out, in six stages.
| Date | Event | Source |
|---|---|---|
| August 11, 2023 | The help-desk calls happen. Clorox later says it caught the intrusion within roughly three hours. | Clorox complaint |
| August 14, 2023 | Clorox tells the SEC it's found unauthorized activity on some IT systems and that operations will keep being disrupted. | SEC Form 8-K |
| September 18, 2023 | Disruption has been widescale, Clorox says. It hopes to restart automated order processing the week of September 25 and calls the hit to first-quarter results material. | SEC Form 8-K |
| Quarter ended September 30, 2023 | About $24 million in incremental expenses gets booked, and net sales are down 20% on the year before. | Form 10-Q |
| August 8, 2024 | In its fiscal 2024 annual report, Clorox puts costs at about $29 million after $30 million in insurance recoveries. | Form 10-K, fiscal 2024 |
| July 22, 2025 | Clorox sues two Cognizant entities for about $380 million. Cognizant pushes back the same day. | Clorox complaint; Reuters |
| August 8, 2025 | The fiscal 2025 annual report adds $70 million in further insurance recoveries and says that's the last of them. | Form 10-K, fiscal 2025 |
| March 25, 2026 | The judge tosses the intentional misrepresentation claim. Breach of contract, breach of the implied covenant, and gross negligence survive. | Law360 |
| May 12, 2026 | A law firm's write-up says the court wouldn't strike the damages claim, because the 2013 contract's liability cap excluded gross negligence. | Hunton Andrews Kurth |
You'll see three different figures quoted, and each measures something else. Here they are, with what each one is based on.
| Figure | Amount | Basis and source |
|---|---|---|
| Damages sought in the lawsuit | About $380 million, including over $49 million in remedial costs | It's a claim. Nobody has awarded or audited it. Source: Complaint, July 22, 2025 |
| Incremental costs, first quarter of fiscal 2024 | About $24 million | Booked expense; no insurance recognized that quarter. Source: Form 10-Q |
| Incremental costs, fiscal 2024 | About $29 million net of $30 million in insurance recoveries (roughly $59 million gross, implied) | Annual financial statements. Source: Form 10-K, fiscal 2024 |
| Further insurance recoveries, fiscal 2025 | $70 million, of which $65 million was business-interruption cover | Money coming back, not money spent. Source: Form 10-K, fiscal 2025 |
| Total insurance recoveries | $100 million | Company-reported; no more expected. Source: Form 10-K, fiscal 2025 |
| Lost sales | Not booked as a charge; net sales fell 20% year over year in the quarter of the attack | Indicator, not a loss figure. Source: Form 10-Q |
Because they're built on different bases, don't add them together or net one against another. Most of the $380 million claim is business interruption, which turns up as lost sales, not as a cost line.
Some widely shared coverage treats the claim as if it were the cost of the attack. Ars Technica headlined its story "After $380M hack." Nothing in Clorox's own filings comes close to that amount.
Most summaries stop at the reset calls. The second half of the complaint is about what happened after the intrusion was spotted, and for incident-response planners it's the more useful part. Cognizant disputes every point.
By Clorox's account, it spotted the intrusion within roughly three hours and had the attacker out within five days. Whoever turns out to be right, there's a planning lesson here. The vendor running your front door is often the one you'll need to reach at night to shut it.
Clorox pleaded four causes of action: breach of contract, breach of the covenant of good faith and fair dealing, gross negligence, and intentional misrepresentation. In a statement to reporters, Cognizant's chief communications officer said "Cognizant did not manage cybersecurity for Clorox." Its argument is that it was hired for a narrow slice of help-desk work.
The March 25, 2026 ruling threw out the misrepresentation claim and kept the other three alive. According to the Hunton Andrews Kurth analysis, the court treated credential handling and MFA management as critical security functions rather than low-level administrative tasks. As of September 1, 2026, there's been no finding of liability, no damages award, and no settlement or trial date made public.
Every stage of the chain had a control that could have broken it. Several were already written into Clorox's own procedure.
| Stage | Control | What it would have broken |
|---|---|---|
| First reset call | Point callers to the self-service reset tool. Or check the manager's name and internal username, then email both the employee and the manager (Clorox's own January 2023 procedure) | Call 1 and every call after it |
| Repeat resets | If one account asks for several password or MFA resets in a short space of time, a supervisor looks first | Calls 2 and 3 |
| Phone-number change | Changing the SMS-MFA number counts as its own high-risk action, needing a callback to the old number or a manager's sign-off | Takeover of the second factor |
| Privileged second target | Same checks for every account, tougher ones for IT security staff | Calls 4 and 5 |
| First login after reset | Conditional access that flags an unfamiliar device, place, or time, even after MFA passes | Initial use of the stolen account |
| Vendor oversight | Contract terms covering incident-response times and audit rights, plus the occasional test call to the outsourced desk | The gap between what the policy said and what agents did |
Switching to phishing-resistant MFA (FIDO2) only helps if enrolling a replacement key takes the same proof of identity as the first enrollment did. If it doesn't, the reset path is still the weakest point.
Every credential or MFA reset is a security event. Don't let it disappear into the ticket queue. If an account gets a password reset, an MFA reset, and a new phone number on the same day, someone should be alerted.
Score agents on how well they check who's calling, not just on how fast they close the call. An agent who volunteers to reset "two MFA applications" is following a speed incentive, not a security one.
Reset procedures, incident-response timelines, and audit rights belong in the outsourcing contract itself. As the Clorox ruling shows, what's carved out of a liability cap can matter as much as the cap does.
The published transcript excerpts make good service-desk training material. They show that the dangerous call is the dull one, a lockout with no drama at all. The same pattern appears at MGM Resorts, at Caesars Entertainment, and in the 2020 Twitter phone-phishing breach.
Clorox has never said so. Its complaint against Cognizant doesn't use the words ransom, extortion, or exfiltration. Its SEC filings talk about damaged IT infrastructure and systems taken offline, but they don't name any malware. A few vendor write-ups call it ransomware. None of the primary sources in this case file back that up. So for now, treat the ransomware label as unconfirmed.
Reuters and other outlets attribute the intrusion to Scattered Spider, the group also linked to the 2023 MGM Resorts and Caesars Entertainment breaches. Clorox's complaint calls the attacker only a cybercriminal and does not name a group, so the attribution rests on press reporting rather than on a court filing.
That depends on which number you mean. Clorox's fiscal 2024 annual report records about $29 million in costs after $30 million of insurance recoveries, implying about $59 million gross. Its lawsuit seeks about $380 million, mostly for business interruption. Total insurance recoveries reached $100 million, and the company says it expects no more. Don't add any of these figures together.
Clorox says Cognizant ran the service desk for about a decade under a 2013 agreement and failed to follow the identity checks Clorox specified before resetting credentials. It also blames Cognizant for a slow incident response. Cognizant says it performed a narrow help-desk role reasonably and did not manage Clorox's cybersecurity. The court hasn't decided who's right.
Not by itself. The attacker didn't break MFA. The service desk reset it and changed the phone number that got the SMS codes. Phishing-resistant keys only help if replacing one takes strong proof of identity. For the prompt-flooding version of this problem, see how to prevent MFA fatigue.

Social Engineering Examples. “Clorox Help-Desk Vishing Hack (2023): Five Calls, Two Accounts, and a $380M Claim”. Accessed 3 November 2026. https://socialengineeringexamples.com/clorox-cognizant-helpdesk-vishing-2023
Clorox's complaint does not detail how the attacker learned employee names, but Scattered Spider, the group press coverage attributes this intrusion to, is widely reported (Reuters, CSO Online) as specializing in researching target-company staff and identifying which outsourced IT vendor or help desk a company uses, likely how the attacker identified at least two real Clorox employees, a general staffer and a named IT security team member, plausible enough to impersonate convincingly by phone.
Employee-facing OSINT exposure (roles, org charts, and knowledge of which vendor runs a company's help desk) is very hard to eliminate at enterprise scale; the realistic control assumes attackers already have this and hardens the reset process it gets used against, rather than trying to hide employee identities.
Per the complaint and the call transcripts quoted in it, the caller phoned Cognizant's outsourced Clorox Service Desk posing as "Employee 1," claimed to be locked out without a VPN or Okta password, and a Cognizant agent reset the password immediately and read it aloud, with none of the identity-verification steps Clorox says it had specified (the MyID self-service tool, or manager name plus MyID username followed by confirmation emails to the employee and manager).
Mandatory use of a self-service verification tool before any human agent performs a manual reset, or, when self-service is unavailable, a hard requirement to verify manager name plus internal username and send simultaneous confirmation emails to the employee and manager, would have stopped the very first call.
On that same first call, after the password reset, the caller said his Microsoft MFA was not working and the agent reset it. Posing as the same employee, the caller phoned a second time and had the Microsoft MFA reset again, then twenty minutes later called a third time and had the Okta credential reset again. Per the complaint, no agent asked why one employee needed repeated resets in such a short window.
Rate-limiting or automatically flagging multiple credential or MFA reset requests for the same account within a short window, and routing them to mandatory supervisor review, closes off the escalation pattern the attacker relied on.
The caller pushed further and asked the agent to change the phone number tied to Employee 1's SMS-based MFA, which the agent also did, giving the attacker full control of both the password and the second authentication factor.
Treating any change to the phone number or device tied to SMS-based MFA as a separate, higher-scrutiny action, such as requiring an out-of-band callback to the previously registered number or manager sign-off, keeps a single phone call from fully taking over both authentication factors.
With Employee 1's password and both MFA factors under attacker control, the intruder logged into Clorox's Okta-federated network and, per the complaint, used that access to identify a second, more privileged target working in Clorox's IT security group.
Conditional-access policies that flag logins from unfamiliar devices, locations, or times even after valid credentials and MFA are presented can catch the moment initial access is used, before an intruder can browse for a second target.
The attacker called the Cognizant service desk again posing as "Employee 2," and across two calls obtained a password reset plus resets of two separate MFA applications, with an agent proactively offering to reset both after noticing two MFA methods on the account, again with no identity verification.
The same help-desk verification controls from Stages 2 through 4 apply regardless of which employee is targeted; treating every reset request as equally high-risk, rather than assuming an IT-security employee's account merits less scrutiny, prevents a repeat of the same playbook against a more privileged target.
Using Employee 2's compromised IT-security-team credentials, the intruder established persistence and moved laterally inside Clorox's environment, expanding from a single compromised account to broader network reach.
Network segmentation and least-privilege access limiting what a single compromised account, even one belonging to IT security staff, can reach, plus monitoring for anomalous lateral movement and privilege use, narrows what an intruder can do even after two accounts are fully compromised.
The intrusion "paralyzed" Clorox's corporate network, per the complaint, forcing systems offline, pausing manufacturing, and requiring weeks of manual order processing. Neither the complaint nor Clorox's SEC filings state whether the ultimate goal was data theft, extortion, or disruption itself: the complaint never uses the words ransom, extortion, or exfiltration, and never names a threat-actor group. Clorox alleges the business impact was severe enough to underlie a $380 million damages claim, a pleaded figure rather than an awarded or audited one.
Rapid detection and containment, which Clorox says it achieved (detecting the intrusion within roughly three hours and ejecting the attacker within five days), plus tested business-continuity and manual-fallback procedures, limits how long a disruptive intrusion can persist; contractual security SLAs, audit rights over outsourced vendors, and periodic vishing red-team testing of the help desk are what would keep the Stage 2 through 6 controls actually enforced by a third party.
