Destructive KillDisk Malware Turns Into Ransomware (securityweek.com)
wiredmikey writes from a report via SecurityWeek: A recently discovered variant of the KillDisk malware encrypts files and holds them for ransom instead of deleting them. Since KillDisk has been used in attacks aimed at industrial control systems (ICS), experts are concerned that threat actors may be bringing ransomware into the industrial domain. CyberX VP of research David Atch told SecurityWeek that the KillDisk variant they have analyzed is a well-written piece of ransomware, and victims are instructed to pay 222 bitcoins ($210,000) to recover their files, which experts believe suggests that the attackers are targeting "organizations with deep pockets." From the report: "The ransomware is designed to encrypt various types of files, including documents, databases, source code, disk images, emails and media files. Both local partitions and network folders are targeted. The contact email address provided to affected users is associated with Lelantos, a privacy-focused email provider only accessible through the Tor network. The Bitcoin address to which victims are told to send the ransom has so far not made any transactions. Atch pointed out that the same RSA public key is used for all samples, which means that a user who receives a decryptor will likely be able to decrypt files for all victims. According to CyberX, the malware requires elevated privileges and registers itself as a service. The threat terminates various processes, but it avoids critical system processes and ones associated with anti-malware applications, likely to avoid disrupting the system and triggering detection by security products."
My meme folders aren't worth $210,000!
Color me shocked.
222 BTC ~ 216K US dollars
and climbing fast
So can every KillDisk user upgrade now, to fix the deleted-files problem? Or does the ransom change need to be pulled by a bunch of different branch maintainers first?
"Believe me!" -- Donald Trump
Writing a program that encrypts files is pretty straightforward. Getting it to run on the victim's computer is the tricky bit. Can anyone provide more information about how the payload is delivered?

These things all have the same solution: restore from your daily backup, which should not be pushed from the machine in question, and should be well tested for recoverability. Even for personal in-home computing, the refrain since the 1970's has been "make backups". If you are still not doing t his in 2016, you deserve what you get. It isn't just malicious hackers that are a threat, it's hardware failures, accidents, and more.
There is no reason to ever consider paying such ransom.
And also, secure your systems so it doesn't happen to you again in the future.
I get mails all the time that require me to rename z_p, piz, txt and whatever else to zip to open them because things are so locked down that the administrators can't even do their jobs to get security patches for their products due to some overzealous corporate firewall that tries to block any info from getting in. Try to loosen the rules and you're looking at a month spent on a change request that will probably never go anywhere. Some of them have somehow added their own vendors' sites to blocklists and not even public ones so we have no idea who to even appeal to. This is quite common in the military where some McAfee product will always be causing severe harm and I'm sure they pay out their rear ends for "support" that doesn't amount to anything. Or perhaps they suffer breakage based on ridiculous settings that got added to a STIG.

"I know of three popular sites that use ClarityRay-like scripts: WIRED, the INQUIRER, and The Atlantic. All three of them admit that they can't tell the difference between tracking blockers, such as Ghostery, Disconnect, and Firefox Private Browsing, from ad blockers" - by tepples ( 727027 ) on Wednesday December 28, 2016 @09:58PM (#53569297)
Detecting browser addons = trivial & here's the proof (dumping them via script) https://webdevwonders.com/detecting-firefox-add-ons/
Thus, If clarityray wants to detect ANY browser addons?? That's how EASY it is to block them!
Can't do that to hosts that way (not an addon running in SLOWER usermode clotting up browsers w/ messagepassing, ram/cpu & other forms of I/O overheads - hosts are kernelmode FASTER & do the job BEFORE addons work!)

No. I use resources for results. Saving 60MB of RAM by turning of my extensions is not a 'saving'.
REAL attacks stalled by h0sts & not 'edge'
I'm calling your DNS protection (poisoned, down, request tracking) 'edge'. Learn to read.
and ... your file stopped a bunch of stuff. One of which you claim in the list was Stegano. Which went undetected for 2 years. Your 'solution' was useless and what kept you safe was preventing scripts from running. But you go ahead and gloss over that because it doesn't fit your narrative.
PROOF ads = up to 40% of a site's pages via bandwidth analysis
Do you _ever_ read anything you link to, or do you just skim?
The study looked at the effect of Adblock Plus (win for extensions!). The 40% figure was arrived at by considering video only. More, the page itself was not 40% ads (as you originally claimed). Looking at the study, the increase in sessions suggest that the ads were spawned as separate pages/connections.
Gb's of RAM = DNS
The last time you referenced this you seemed to link to a list of problems with Windows Server 2008 running a DNS server. Is this what you are talking about? I've run DNSmasq on routers with a total of 32MB or RAM. Orders of magnitude my ass.
You think people here =e STUPID to fall for weak "jedi mind tricks" when ORDERS OF MAGNITUDE are a difference
No. I don't think you are stupid, either. I do think you are obsessed and unable to argue rationally or evaluate evidence that contradicts the position you are so heavily invested in. OK, to be fair, I've just called you a crank.

Yup and you've got the awards from a decade ago to prove it.

Man - must be one hell of a case of indigestion (butthurt is more like it) that you keep coming to your dismay (let alone MALNUTRITION as "eating your words" != good nutrition - hopefully you die of starvation soon if not shame)... apk
You use bs: Hosts use many orders of magnitude less vs. addons & DNS. Using more = better (doing less)? Avg. 6mb hosts = FAR LESS vs. 64mb UBlock (or 128mb Adblock) & hosts do more for less.
Your "illogic logic" astounds, lol!

Like the script blocker that's stopping them from running? Tell me how that works,again.
And you are still avoiding providing an example of ClarityRay in use. Tell me again how I'm failing.

I know. It's creepy. And then you claim that people stalk _you_.
I have YET to attack you 1st
Lie. I criticise your off-topic or 'spammy' posts. That's not attacking you. You, on the other hand, never fail to call me names, mock me, or wish that I were dead. That's attacking me. Not my arguments. Not my words or ideas. Me. I have not attacked you. I've attacked your ideas. I've attacked your posts. But not you. Do you understand? Can you read? Have you read this, or are you just skimming it so you can 'beat' me with some off-topic link or 'proof'?
There's a difference. It's important to me. Perhaps not so much with you.
facts!
Right. Like your 6 year old code snippet that only runs if I allow scripts that you offer as 'proof' when I ask for an example that ClarityRay is in use.
Yeah. Great work.
YT
60MB memory is trivial on a machine with 4GB RAM. You fail to address this and just keep parroting 'more for less'. Boring.
I can run DNSmasq on a router with 32MB of memory, but you keep going on about errors on Windows 2008. You don't even bother addressing this. Weak.
You didn't post a bandwidth analysis. You made a claim. It was exaggerated. You corrected and posted a summary of a study which looked at bandwidth. Which you still haven't read. And which recommended Adblock. Exaggeration. Citation fail.
DNS ... linking to a spam of other links that are an undifferentiated mess of everything you can find that has the word 'DNS' and 'problem' in it is neither an argument nor proof/disproof. I made specific criticisms of your position. I read, tried to understand and replied. If you cannot do the same, then there is little point in continuing this.
Another time, APK. We'll see if you are capable of a realy argument, yet.

Don't use software written by a forum spammer who stalks anyone who criticizes his software or advertising methods.

Why even risk it when there's better open source software out there anyway written ny people that won't stalk your forum posts with nonsense?
