*1023OPINION
FRIEDLAND, Circuit Judge:
In January 2012, hackers breached the servers of online retailer Zappos.com, Inc. ("Zappos") and allegedly stole the names, account numbers, passwords, email addresses, billing and shipping addresses, telephone numbers, and credit and debit card information of more than 24 million Zappos customers. Several of those customers filed putative class actions in federal courts across the country, asserting that Zappos had not adequately protected their personal information. Their lawsuits were consolidated for pretrial proceedings.
Although some of the plaintiffs alleged that the hackers used stolen information about them to conduct subsequent financial transactions, the plaintiffs who are the focus of this appeal ("Plaintiffs") did not. This appeal concerns claims based on the hacking incident itself, not any subsequent illegal activity.
The district court dismissed Plaintiffs' claims for lack of Article III standing. In this appeal, Plaintiffs contend that the district court erred in doing so, and they press several potential bases for standing, including that the Zappos data breach put them at risk of identity theft.
We addressed standing in an analogous context in Krottner v. Starbucks Corp. ,
I.
When they bought merchandise on Zappos's website, customers provided personal identifying information ("PII"), including their names, account numbers, passwords, email addresses, billing and shipping addresses, telephone numbers, and credit and debit card information. Sometime before January 16, 2012, hackers targeted Zappos's servers, stealing the PII of more than 24 million of its customers, including their full credit card numbers.
In these suits, Plaintiffs alleged an "imminent" risk of identity theft or fraud from the Zappos breach. Relying on definitions *1024from the United States Government Accountability Office ("GAO"), they characterized "identity theft" and "identity fraud" as "encompassing various types of criminal activities, such as when PII is used to commit fraud or other crimes," including "credit card fraud, phone or utilities fraud, bank fraud and government fraud."
The Judicial Panel on Multidistrict Litigation transferred several putative class action lawsuits alleging harms from the Zappos data breach to the District of Nevada for pretrial proceedings. After several years of pleadings-stage litigation, including a hiatus for mediation, the district court granted in part and denied in part Zappos's motion to dismiss the Third Amended Consolidated Complaint ("Complaint") and granted Zappos's motion to strike the Complaint's class allegations. The court distinguished between two groups of plaintiffs: (1) plaintiffs named only in the Third Amended Complaint who alleged that they had already suffered financial losses from identity theft caused by Zappos's breach, and (2) plaintiffs named in earlier complaints who did not allege having already suffered financial losses from identity theft.
The district court ruled that the first group of plaintiffs had Article III standing because they alleged "that actual fraud occurred as a direct result of the breach." But the court ruled that the second group of plaintiffs (again, here referred to as "Plaintiffs") lacked Article III standing and dismissed their claims without leave to amend because Plaintiffs had "failed to allege instances of actual identity theft or fraud." The parties then agreed to dismiss all remaining claims with prejudice, and Plaintiffs appealed.
II.
We review the district court's standing determination de novo. See Maya v. Centex Corp. ,
a plaintiff must show (1) it has suffered an "injury in fact" that is (a) concrete and particularized and (b) actual or imminent, not conjectural or hypothetical; (2) the injury is fairly traceable to the challenged action of the defendant; and (3) it is likely, as opposed to merely speculative, that the injury will be redressed by a favorable decision.
Friends of the Earth, Inc. v. Laidlaw Envtl. Servs. (TOC), Inc. ,
III.
We addressed the Article III standing of victims of data theft in *1025Krottner v. Starbucks Corp. ,
A.
Before analyzing whether Krottner controls this case, we must determine whether Krottner remains good law after the Supreme Court's more recent decision in Clapper v. Amnesty International USA ,
As a three-judge panel, we are bound by opinions of our court on issues of federal law unless those opinions are "clearly irreconcilable" with a later decision by the Supreme Court or our court sitting en banc. Miller v. Gammie ,
The plaintiffs in Clapper challenged surveillance procedures authorized by the Foreign Intelligence Surveillance Act of 1978-specifically, in 50 U.S.C. § 1881a (2012) (amended 2018).
The Court then held that the plaintiffs' theory of injury was too speculative to constitute a "certainly impending" injury.
*1026
(1) the Government will decide to target the communications of non-U.S. persons with whom they communicate; (2) in doing so, the Government will choose to invoke its authority under § 1881a rather than utilizing another method of surveillance; (3) the Article III judges who serve on the Foreign Intelligence Surveillance Court will conclude that the Government's proposed surveillance procedures satisfy § 1881a's many safeguards and are consistent with the Fourth Amendment; (4) the Government will succeed in intercepting the communications of respondents' contacts; and (5) respondents will be parties to the particular communications that the Government intercepts.
Unlike in Clapper , the plaintiffs' alleged injury in Krottner did not require a speculative multi-link chain of inferences. See Krottner ,
And although the Supreme Court focused in Clapper on whether the injury was "certainly impending," it acknowledged that other cases had focused on whether there was a "substantial risk" of injury.
For all these reasons, we hold that Krottner is not clearly irreconcilable with Clapper and thus remains binding.
*1027B.
We also conclude that Krottner controls the result here. In Krottner , we held that the plaintiffs had "alleged a credible threat of real and immediate harm stemming from the theft of a laptop containing their unencrypted personal data."
Plaintiffs allege that the type of information accessed in the Zappos breach can be used to commit identity theft, including by placing them at higher risk of "phishing" and "pharming," which are ways for hackers to exploit information they already have to get even more PII. Plaintiffs also allege that their credit card numbers were within the information taken in the breach-which was not true in Krottner .
Indeed, the plaintiffs who alleged that the hackers had already commandeered their accounts or identities using information taken from Zappos specifically alleged that they suffered financial losses because of the Zappos data breach (which is why the district court held that they had standing). Although those plaintiffs' claims are not at issue in this appeal, their alleged harm undermines Zappos's assertion that the data stolen in the breach cannot be used for fraud or identity theft. In addition, two plaintiffs whose claims are at issue in this appeal say that the hackers took over their AOL accounts and sent *1028advertisements to people in their address books.
Zappos contends that even if the stolen data was as sensitive as that in Krottner , too much time has passed since the breach for any harm to be imminent. Zappos initially contended on appeal that the relevant time at which to assess standing was the present. But it could not offer any support for that contention. After our opinion was initially filed, Zappos sought rehearing on this issue, urging us to read Rockwell International Corp. v. United States ,
Plaintiffs also specifically allege that "[a] person whose PII has been obtained and compromised may not see the full extent of *1029identity theft or identity fraud for years." And "it may take some time for the victim to become aware of the theft."
Assessing the sum of their allegations in light of Krottner , Plaintiffs have sufficiently alleged an injury in fact based on a substantial risk that the Zappos hackers will commit identity fraud or identity theft.
C.
The remaining Article III standing requirements are also satisfied. Plaintiffs sufficiently allege that the risk of future harm they face is " 'fairly traceable' to the conduct being challenged"-here, Zappos's failure to prevent the breach. Wittman v. Personhuballah , --- U.S. ----,
That hackers might have stolen Plaintiffs' PII in unrelated breaches, and that Plaintiffs might suffer identity theft or fraud caused by the data stolen in those other breaches (rather than the data stolen from Zappos), is less about standing and more about the merits of causation and damages. As the Seventh Circuit recognized in Remijas v. Neiman Marcus Group, LLC ,
The injury from the risk of identity theft is also redressable by relief that could be obtained through this litigation. See Lujan ,
IV.
For the foregoing reasons, we REVERSE the district court's judgment as to Plaintiffs' standing and REMAND .
We address an issue raised by sealed briefing in a concurrently filed memorandum disposition.
Although Zappos asserts in its briefs that the hackers stole only the last four digits of customers' credit card numbers, it has presented its arguments as a facial, not a factual, attack on standing. See Safe Air for Everyone v. Meyer ,
Plaintiffs did not provide a precise cite but appear to be referring to the description of identity theft in a report entitled Personal Information , which explains that "[t]he term 'identity theft' is broad and encompasses many types of criminal activities, including fraud on existing accounts-such as unauthorized use of a stolen credit card number-or fraudulent creation of new accounts-such as using stolen data to open a credit card account in someone else's name." U.S. Gov't Accountability Office, GAO-07-737, Personal Information: Data Breaches are Frequent, but Evidence of Resulting Identity Theft is Limited; However, the Full Extent is Unknown 2 (2007).
50 U.S.C. § 1881a authorizes electronic surveillance of foreign nationals located abroad under a reduced government burden compared with traditional electronic foreign intelligence surveillance. Compare
The Court noted that the plaintiffs in Clapper had not alleged a substantial risk because their theory of injury relied on too many inferences. Clapper ,
Our conclusion that Krottner is not clearly irreconcilable with Clapper is consistent with post-Clapper decisions in our sister circuits holding that data breaches in which hackers targeted PII created a risk of harm sufficient to support standing. For example, the D.C. Circuit held in Attias v. Carefirst, Inc. ,
Plaintiffs include in the Complaint some emails sent to Zappos from other customers saying that their credit cards were fraudulently used following the breach.
We use the terms "identity fraud" and "identity theft" in accordance with the GAO definition Plaintiffs rely on in the Complaint. See supra note 3 and accompanying text.
The district court held that these plaintiffs nonetheless lacked standing because they had not suffered "additional misuse" or "actual damages" from the data breach.
Zappos's reliance on these cases is also unconvincing, as these cases do not actually address whether standing is measured at the time of an initial complaint or at the time of an amended complaint, as opposed to whether the allegations in an amended complaint may sometimes be considered in evaluating whether there was standing at the time the case was originally filed or whether an amended complaint may be considered a supplemental pleading under Federal Rule of Civil Procedure 15(d).
Plaintiff Robert Ree does not clearly allege a risk of future identity theft. But even assuming Ree would not have had standing on his own based on his original Complaint, only one Plaintiff needs to have standing for a class action to proceed. See Bates v. United Parcel Serv., Inc. ,
Of course, as litigation proceeds beyond the pleadings stage, the Complaint's allegations will not sustain Plaintiffs' standing on their own. See Lujan v. Defs. of Wildlife ,
This conclusion is consistent with the Fourth Circuit's decision in Beck v. McDonald ,
Clapper is not to the contrary. In Clapper , the Supreme Court held that, even assuming the plaintiffs were going to be surveilled, any future surveillance could not be traced to the challenged statute because the risk of being surveilled did not increase with the addition of the new statutory tool.
Plaintiffs need only one viable basis for standing. See Douglas Cty. v. Babbitt ,
