[QUOTE="Andy Ful, post: 929557, member: 32260"] There are two conclusions after watching this video: [LIST=1] [*]The test shows the well known potential weakness of cloud solutions that can be used by malware. [*]The test is useless for most home users in the world because this weakness is exploited very rarely in the wild. [/LIST] It could have some value for Enterprises, but WD free is not used there. In the home environment, the coincidence of losing the Internet connection and running something malicious is thousands of times smaller than running malware when being connected. Who would care about such an improbable event ??? Another possibility is the scenario as follows: Fresh malware or a 0-day exploit (FM) ----> FM downloads/drops the encrypted older malware (OM) ------> FM breaks the Internet connection -------> FM decrypts and runs OM The advantage of such an attack is that initial malware can be simple and performs only a few suspicious actions. So it can be missed by an AV with an Internet connection. But, such malware samples are rare (so far). Furthermore, malware likes Internet connection to call home. Anyway, this could be an alternative to malware polymorphism and obfuscation. In any scenario, the test results cannot have a visible impact on the security of the home users (so far). We will see what can happen in the future. [/QUOTE]
