Supply chains, AI, and the cloud: The biggest failures (and one success) of 2025
In a roundup of the top stories of 2024, Ars included a supply-chain attack that came dangerously close to inflicting a catastrophe for thousands—possibly millions—of organizations, which included a large assortment of Fortune 500 companies and government agencies. Supply-chain attacks played prominently again this year, as a seemingly unending rash of them hit organizations large and small.
For threat actors, supply-chain attacks are the gift that keeps on giving—or, if you will, the hack that keeps on hacking. By compromising a single target with a large number of downstream users—say a cloud service or maintainers or developers of widely used open source or proprietary software—attackers can infect potentially millions of the target’s downstream users. That’s exactly what threat actors did in 2025.

If you’re online, you’re generating a constant stream of information about yourself — sometimes voluntarily, sometimes unwittingly — that is assembled and used to craft your online experience. And generate wealth for data brokers. Meanwhile, designers and managers of the digital infrastructure on which the world depends are engaged in a never-ending effort to thwart attempts, by both criminal enterprises and state actors, to exploit vulnerabilities in those systems.
