Security Evaluation

1. Device Security

Criterion	Value	Proof	Comment
Known hardware tampering	Rare	🔗 Proof	No documented hardware tamper shortcut, but the bulb is a sealed unit whose flash can be dumped after physical disassembly.
Known vulnerabilities	Very common	[1] [2] [3] 🔗 Proof	Four CVEs cover this exact model: replayed session key (7.5), auth code leak over UDP, TSKEP authentication leak and static IV in AES-128-CBC.
Prior attacks	Rare	🔗 Proof	Researchers demonstrated taking over the bulb to reach other household devices, but no in-the-wild campaign or KEV entry.
Updatability	Very common	🔗 Proof	All four issues are fixed in firmware 1.2.4; the bulb updates through the Tapo app.
Category Score	Score: 2 / 3

2. System Security

Criterion	Value	Proof	Comment
Authentication with other systems	No	🔗 Proof	There is no device-to-device authentication model; trust rests entirely on a cloud session key that can be replayed.
Communications	Encrypted with obselete encryption	🔗 Proof	Traffic is AES-128-CBC encrypted but with a static IV and a replayable session key, which is obsolete use of a sound cipher.
Storage	No encryption	🔗 Proof	No local storage and no secure element; credentials sit in app storage and are recoverable through the TSKEP flaws.
Category Score	Score: 3 / 3

3. User Authentication

Criterion	Value	Proof	Comment
Account management	Absent	🔗 Proof	The bulb has no account management of its own; it inherits the single Tapo cloud account with no roles or separation.
Authentication	Absent	🔗 Proof	No authentication on the local control protocol, so any host on the same network that knows the message format can drive the bulb.
Brute-force protection	Absent	🔗 Proof	No brute-force protection on the local protocol and the UDP authentication code can be captured rather than guessed.
Event logging	Absent	🔗 Proof	No access log on the device and no export of authentication events; the app only shows on/off history.
Passwords	Default/Common/Easy to guess	🔗 Proof	No local credential at all; the device depends on the cloud account password, which never rotates per device.
Category Score	Score: 3 / 3
