 **Need #3: Resiliency to exploits**
 
-A vulnerability in any application can be targeted with exploits - a severe vulnerability can allow an adversary to hack your system, such as by permitting [Remote Code Execution](https://en.wikipedia.org/wiki/Arbitrary_code_execution). Cwtch does [fuzz testing](https://openprivacy.ca/discreet-log/07-fuzzbot/) to find bugs.

 Signing up for a Signal account is difficult to do anonymously. The account is tied to a phone number that the user must retain control of - due to [changes in "registration lock"](https://blog.privacyguides.org/2022/11/10/signal-number-registration-update/), it is no longer sufficient to register with a disposable phone number. An anonymous phone number can be obtained [on a burner phone or online](https://anonymousplanet.org/guide.html#getting-an-anonymous-phone-number) and must be maintained  as long as you’re using it, which takes some technical know-how and likely some money, limiting the amount of people who will do this. 
 
-Another barrier to anonymous registration is that Signal Desktop will only work if Signal is first registered from a smartphone. For users familiar with the [command line](/glossary/#command-line-interface-cli), it is possible to register an account from a computer using [Signal-cli](http://wmj5kiic7b6kjplpbvwadnht2nh2qnkbnqtcv3dyvpqtz7ssbssftxid.onion/about.privacy/messengers-on-tails-os/-/wikis/HowTo#signal). The [VoIP](/glossary#voip-voice-over-internet-protocol) account used for registration would have to be obtained anonymously.

 These barriers to anonymous registration mean that Signal is rarely used anonymously. This has significant implications if the State gains [physical](/glossary/#physical-attacks) or [remote](/glossary/#remote-attacks) access to the device. One of the primary goals of State surveillance of anarchists is [network mapping](https://www.notrace.how/threat-library/techniques/network-mapping.html), and it's common for them to gain physical access to devices through [house raids](https://www.notrace.how/threat-library/techniques/house-raid.html) or arrests. For example, if police bypass your device's [authentication](https://www.notrace.how/threat-library/techniques/targeted-digital-surveillance/authentication-bypass.html), they can identify Signal contacts (as well as the members of any groups you are in) simply by their phone numbers, if those contacts haven't changed their settings to hide their phone number.
