Sichuan Changhong Electric Ltd. — 11 prefixes (MA-L)

Sichuan Changhong Electric Ltd. is one of China's largest consumer-electronics manufacturers, founded in 1958 and headquartered in Mianyang, Sichuan, best known internationally under its CHiQ television brand. The IEEE MA-L registry lists eleven separate 24-bit OUI blocks assigned to the exact organization string "Sichuan Changhong Electric Ltd.", split across two slightly different registered-address strings — a larger group of eight prefixes anchored on East MianXin Road and a smaller group of three on East Mianxing Road / a High-Tech Park address — which read as successive registration batches rather than distinct subsidiaries. Changhong's network-facing product line centers on Android-based CHiQ/NeoNet smart TVs and DVB-C/S/S2/T2/IPTV set-top boxes, sold domestically and exported to India, Indonesia, the UK, Germany, and Pakistan. A January 2016 press-reported Android backdoor campaign (abusing CVE-2014-7911) named Changhong alongside several other smart-TV/STB brands, though the underlying flaw was a platform-level Android issue rather than a Changhong-specific firmware vulnerability. Two adjacent but legally distinct registrants — "Sichuan Changhong Network Technologies Co., Ltd." and "Changhong (Hongkong) Trading Limited" — hold their own separate OUI blocks under similar names and should not be merged into this entry.

Security context

named (with Konka, Mi, Philips, Panasonic, Sharp) in January 2016 press coverage of an Android smart-TV/STB backdoor campaign abusing CVE-2014-7911, distributed via malicious "H.TV"-branded apps targeting US/Canada viewers; this is an ecosystem-level Android privilege-escalation flaw, not a Changhong-specific firmware CVE — the vendor link comes from press coverage of the malware campaign, not the CVE record itself [Likely] — https://www.securityweek.com/backdoors-infiltrate-android-powered-smart-tvs/; https://threatpost.com/authentication-bug-android-smart-tv-data-theft/160025/; https://www.trendmicro.com/en_hk/about/newsroom/press-releases/2016/20160120073644.html

Dates

Unknown / not applicable — IEEE's cached MA-L CSV publishes no assignment/registration date for any of these 11 rows. A third-party aggregator (maclookup.app) displays bookkeeping fields "First registration: 07 April 2005 / Last updated: 03 April 2020" — this is a database artifact of the aggregator's own crawl, not an IEEE fact, and is not recorded as a date here [Confirmed absence of an IEEE date; third-party figure noted only as a caveat, not attributed] — the IEEE MA-L registry; https://maclookup.app/vendors/sichuan-changhong-electric-ltd

Related-but-distinct entities (do not conflate)

"Sichuan Changhong Network Technologies Co., Ltd." — separate legal entity, same city, OUIs 24:D9:04, A0:C0:16; "CHANGHONG (HONGKONG) TRADING LIMITED" — Hong Kong entity, OUIs AC:AC:E2, E8:C6:E6; several Shenzhen-registered orgs (SDMC/CP, Lemon Network Technology, XGTEC Technology) whose registry address is a building literally named "Changhong Science & Technology Mansion" — unrelated tenants, not Changhong Electric itself

[Confirmed] — the IEEE MA-L registry

IANA reference

blank — not applicable to OUI/MA-L registry entries (IANA references apply to ASN/RIR entries, not IEEE MAC assignments) [Confirmed]

Analyst note

an OUI match on any of these 11 prefixes identifies genuine Sichuan Changhong Electric hardware (smart-TV / STB class devices); don't conflate with the same-name-adjacent Shenzhen tenant orgs or with the distinct "Sichuan Changhong Network Technologies" sibling entity noted above.
