Marriott International Inc.
Breach
Rankiteo Explanation
Attack with significant impact with customers data leaks
Description: Marriott International Inc. faced a major data breach involving its Starwood-branded hotels, exposing the personal information of up to 383 million guests. The breach, which led to consolidated litigation, included sensitive customer data such as names, addresses, passport numbers, and payment details. The city of Chicago filed claims against Marriott, but the case was dismissed with prejudice after a settlement was reached. The incident underscores the severe consequences of large-scale data leaks, particularly in the hospitality sector, where trust and data security are critical. The breach not only risked financial fraud and identity theft for affected guests but also damaged Marriott’s reputation, leading to legal repercussions and regulatory scrutiny. The scale of the exposure affecting hundreds of millions highlights the systemic vulnerabilities in handling customer data across global operations.

Marriott International, Inc.
Breach
Rankiteo Explanation
Attack with significant impact with customers data leaks
Description: The California Office of the Attorney General disclosed a major data breach at Marriott International, Inc. on November 30, 2018, stemming from an unauthorized access to the Starwood guest reservation database. The breach, which began on or before September 10, 2018, exposed the records of approximately 500 million guests, with 327 million individuals having sensitive personal data compromised. This included names, mailing addresses, email addresses, and encrypted payment card numbers, though the encryption status of the latter was not confirmed to be broken. The incident originated from a vulnerability in Starwood’s systems, which Marriott had acquired in 2016, highlighting a failure in post-merger cybersecurity integration. The breach posed severe risks of identity theft, financial fraud, and reputational damage, given the scale and sensitivity of the exposed data. Regulatory investigations followed, with Marriott facing significant legal and financial repercussions, including fines under GDPR and other data protection laws. The incident underscored critical gaps in third-party risk management and the protection of customer data in large-scale corporate acquisitions.

Description
nimiq/core-rs-albatross is a Rust implementation of the Nimiq Proof-of-Stake protocol based on the Albatross consensus algorithm. Prior to version 1.3.0, two peer-facing consensus request handlers assume that the history index is always available and call blockchain.history_store.history_index().unwrap() directly. That assumption is false by construction. HistoryStoreProxy::history_index() explicitly returns None for the valid HistoryStoreProxy::WithoutIndex state. when a full node is syncing or otherwise running without the history index, a remote peer can send RequestTransactionsProof or RequestTransactionReceiptsByAddress and trigger an Option::unwrap() panic on the request path. This issue has been patched in version 1.3.0.
