In this week's combined Torah portion, Parashat Nitzavim-Vayeilech, Moses gathers the entire nation for a dramatic final assembly. He doesn't just address the leaders. He explicitly includes everyone: "your heads, your tribes, your elders, your officers... from the woodcutter to the water drawer" (Deuteronomy 29:9-10). He then takes it a step further, extending the covenant to "those who are not here with us today" (29:14). Rashi explains that future generations were included in this covenant as well, reinforcing the idea that Jewish identity is not merely an individual credential. It is a continuous chain of trust and mutual responsibility linking past, present, and future.
This ancient concept of a shared chain of trust highlights a major real-world security failure that recently unfolded between Dropbox and Lenovo. Many technology systems rely on "federated login," where one organization trusts another to verify a user's identity so they can access services without creating separate credentials. In this case, Dropbox trusted Lenovo's system to verify user email addresses. The problem was that Lenovo's verification process was not actually confirming ownership of the email addresses being provided. Attackers exploited that weakness by creating Lenovo accounts using email addresses that already existed in Dropbox. Dropbox accepted Lenovo's assertion and granted access to thousands of Dropbox accounts without requiring a password. The attackers did not break encryption or defeat advanced security controls. They simply exploited a trust relationship that was never properly verified.
This breakdown echoes a subtle teaching in Deuteronomy: "The hidden things belong to the Lord our God, but the revealed things belong to us..." Rashi, citing the Talmud, explains that a community is not held responsible for wrongdoing committed entirely in secret. Once a problem becomes visible, however, responsibility shifts to the community to address it. In the digital world, blindly accepting another organization's assurances without verification treats security weaknesses as someone else's problem. Modern cybersecurity has largely moved away from that mindset through what is known as Zero Trust. Even when a trusted partner says, "This user is legitimate," systems still require additional verification before granting access. Trust may begin the process, but verification completes it.
Toward the end of the portion, in Vayeilech, Moses writes down the Torah and entrusts it to the Levites, instructing that it be publicly read every seven years so that the entire nation, including children, can hear it (Deuteronomy 31:10-13). The goal was not simply to preserve a document. It was to create a transparent, repeatable process that ensured everyone understood the covenant and that its contents could not quietly be altered or forgotten.
Following the incident, Dropbox disabled the vulnerable Lenovo integration, reset compromised sessions, and required users to authenticate directly. While those actions were a necessary first step toward repair, what Rambam would describe as the beginning of teshuvah, the deeper lesson remains: true security depends on verifying every link in the chain. Whether in technology, governance, or communal life, trust is important, but trust without verification is often where problems begin.
Good Shabbos!
