> If you installed a Linux system with disk encryption more than a couple of years ago, there's a decent chance it's using a weak key derivation function and someone who cares enough would be in a position to brute-force it. https://mjg59.dreamwidth.org/66429.html has more details and instructions on how to update to a better KDF.
@administrator @aab I'm just guessing, but it could be related to an exploit someone launched against #Mastodon and #Misskey yesterday. From what I read, it brought several instances to their knees. Misskey released a #security patch yesterday.
Tagging this thread with #Fediverse #Security ... whomever made the script obviously read some protocol docs and some source code. With just a little #JavaScript, they were able to knock some #Misskey and #Mastodon instances to their knees.
This isn't the first, and it won't be the last. Remember when someone posted a humongous image and locked up any #GNUSocial instance that tried to download the image? Remember when someone's instance was replaced by some sort of cryptocurrency site and PuSH es from your site to theirs would crash your site because of their site's response? (I'll bet I still have that domain blocked at the firewall.)
We have to stop being naive about the intentions of those in the current migration. The overwhelming majority will have benign, if not good, intentions. But a select few will have bad intentions. Among those intentions is to colonize the Fediverse with #Twitter's culture, to come here and impose that culture of anger and disrespect upon the inhabitants here ... which already happened once with the first wave of people joining #Mastodon instance, except it was Twitter and #Tumblr at that time.
> Researchers have unearthed a discovery that doesn’t occur all that often in the realm of malware: a mature, never-before-seen Linux backdoor that uses novel evasion techniques to conceal its presence on infected servers, in some cases even with a forensic investigation.
> On Thursday, researchers from Intezer and The BlackBerry Threat Research & Intelligence Team said that the previously undetected backdoor combines high levels of access with the ability to scrub any sign of infection from the file system, system processes, and network traffic. Dubbed Symbiote, it targets financial institutions in Brazil and was first detected in November.
