Discussion on the show
In episode 007’s chapter “安全风险集中爆发：漏洞、证书与补丁” (Security risks erupt: vulnerabilities, certificates and patches), Xiangyang Qiaomu says “还有塔塔之前不是把苹果各种都泄露了” (Tata also leaked all sorts of Apple stuff before) (see the line in the Chinese transcript), and Guizang adds “泄露了，都是印度工厂泄露的” (it leaked, from factories in India) (see the line). These are the hosts’ retellings of media reports; details of any leak should follow reliable reporting, and the group versus Tata Electronics should be distinguished by context. See episode 007’s chapter, linked transcript is in Chinese.
Common confusions
- Tata Group vs. Tata Electronics: the former is the parent group; the latter is its electronics and semiconductor manufacturing company established in 2020. “Indian factories” in the show’s topic refers to manufacturing businesses of this kind.
- The certificate incident vs. Tata: the weak-randomness Indian certificate issue discussed in the same chapter concerns certificate issuers and is unrelated to Tata.
