The filing of data breach and other cybersecurity incident-related shareholder derivative lawsuits against corporate boards is nothing new; plaintiffs’ lawyers have been filing these kinds of claims now for several years. However, in recent months, the plaintiffs’ lawyers have shown an increasing inclination to file these claims based on allegations of breach of the duty of oversight. The latest example of this type of claim is the shareholder derivative suit filed this week against the board of T-Mobile USA. Although the plaintiff’s complaint does not expressly use the words “breach of the duty of oversight” or refer to “Caremark duties,” the complaint does refer to the board’s alleged “failure to monitor” and to the board’s alleged failure “to heed red flags” – the very kind of allegations that are at the heart of breach of the duty of oversight claims. A copy of the plaintiff’s complaint in the November 29, 2021 lawsuit can be found here.

Cybersecurity-Related Securities Suit Dismissed
In an interesting development, the U.S. District Court Judge overseeing the cybersecurity-related securities class action lawsuit pending against title insurance company First American Financial Corp. has granted the defendants’ motion to dismiss. The dismissal in the case is interesting because the company had in June 2021 agreed with the SEC to enter a cease-and-desist order and to pay a modest civil penalty to settle charges related to the same cybersecurity incident. The dismissal is also interesting because it shows how plaintiffs’ lawyers have struggled to get traction with cybersecurity-related securities suits. A copy of the Court’s September 22, 2021 order granting the motion to dismiss in the First American securities suit can be found here.

Guest Post: First There was Litigation; And Then There Was Standing
When companies are hit with cybersecurity incidents, class action privacy litigation often follows. However, claimants in these kinds of cases face a threshold challenge of showing they have suffered a sufficient “injury in fact” to establish that they have standing to assert their claims. The following guest post, written by Paul Ferrillo, Kristine Argentine, Emily Dorner, and Alexandra Drury of the Seyfarth Shaw law firm, provides a survey of the current state of play for the standing requirements in this type of litigation. I would like to thank the authors for allowing me to publish their article as a guest post on this site.

SEC Charges Company Over Misleading Cybersecurity-Related Disclosures
In the agency’s latest move underscoring its emphasis on cybersecurity disclosure, the SEC has filed settled charges against the U.K. educational publishing and services company Pearson plc, alleging that the company misled investors about a 2018 data breach. The company, which neither admitted nor denied the charges, agreed to pay a $1 million civil money penalty. The administrative enforcement action, while not the first of its type, does highlight the agency’s heightened focus on cybersecurity disclosure issues. The agency’s August 16, 2021 cease and desist order can be found here. The agency’s August 16, 2021 press release about the order can be found here. Pearson’s statement about the proceeding can be found here.

Two More Chinese Companies Hit with U.S. Securities Suits Following Post-IPO Crackdown by Chinese Regulator
After the news emerged last week that Chinese cybersecurity regulators had cracked down on the ride-sharing firm DiDi Global shortly after the company completed its U.S. IPO, the company was hit with a U.S. securities class action lawsuit. However, DiDi was not the only Chinese company that recently completed a U.S. IPO that was targeted by the Chinese regulator. Two other Chinese companies that completed U.S. IPOs in June – Full Truck Alliance Co. Ltd. and Kanshun Limited – were both also notified that their companies were under review by the cybersecurity regulator. And now both of these companies have also been hit with U.S. securities class action lawsuits, as discussed below.

Chinese Ride-Hailing Firm DiDi Hit With Securities Suit Related to Its Recent IPO
On July 6, 2021, after the Wall Street Journal reported that prior to DiDi’s June 30, 2021 U.S. IPO, government authorities had urged the Chinese ride-hailing firm to postpone the offering, but that the company, under pressure from investors, had gone ahead with the IPO anyway, it seemed that it would only be a matter of time before DiDi would be hit with a U.S. securities lawsuit. Indeed, as it turned out, the same day the Journal article appeared, an investor filed a U.S. securities class action lawsuit against the company. As discussed below, the lawsuit is based on cybersecurity and privacy concerns relating to the company’s ride-hailing app. A copy of the investor’s July 6, 2021 complaint can be found here.
