Exploiting vulnerabilities in Cellebrite UFED and Physical Analyzer

They are implying that future versions of Signal will drop random files on your phone that "may or may not" cause damage to Cellebrite systems.

They are basically putting the threat out that if you use Cellebrite on Signal in the future, you might not get the data you expect, and at worst, it may corrupt the report/evidence.

This also brings into question the chain of custody, as an untrusted device being imaged can alter reports of unrelated devices.

Damn, a chain of custody where the thing in evidence is also part of not only its own chain but also those of other evidence acquired afterwards? I can't imagine what kind of case law exists around that, but I'm sure it's hilarious!

> also those of other evidence acquired afterwards

And prior extracts on the device.

Which is what I don't really understand - it seems like Cellebrite could spin this in their favor so law enforcement would need to purchase a new kit for each device?
