Supply-chain attack using invisible code hits GitHub and other repositories
Attackers used invisible Unicode in supply-chain compromise of GitHub and other repositories.
Unicode that's invisible to the human eye was largely abandoned—until attackers took notice (https://arstechnica.com/security/2026/03/supply-chain-attack-using-invisible-code-hits-github-and-other-repositories/). The supply-chain attack leveraged invisible Unicode to target GitHub and other repositories (https://arstechnica.com/security/2026/03/supply-chain-attack-using-invisible-code-hits-github-and-other-repositories/). Attackers revived previously abandoned invisible Unicode techniques in source code (https://arstechnica.com/security/2026/03/supply-chain-attack-using-invisible-code-hits-github-and-other-repositories/). Multiple code repositories were hit according to the report (https://arstechnica.com/security/2026/03/supply-chain-attack-using-invisible-code-hits-github-and-other-repositories/).
AXIOM: This means the everyday apps and tools we download could quietly carry hidden risks from code we thought was safe, making software updates feel less trustworthy for regular people. It also hints at a messier future for AI, since these sneaky poisons could slip into the massive code piles that train new models.
