Stung By File-Encrypting Malware, Researchers Fight Back
itwbennett (1594911) writes "When Jose Vildoza's father became the victim of ransomware, he launched his own investigation. Diving into CryptoDefense's code, he found its developers had made a crucial mistake: CryptoDefense used Microsoft's Data Protection API (application programming interface), a tool in the Windows operating system to encrypt a user's data, which stored a copy of the encryption keys on the affected computer. Vildoza and researcher Fabian Wosar of the Austrian security company Emsisoft collaborated on a utility called the Emsisoft Decrypter that could recover the encrypted keys. In mid-March Vildoza had launched a blog chronicling his investigation, purposely not revealing the mistake CryptoDefense's authors had made. But Symantec then published a blog post on March 31 detailing the error."
The myth that the 'security' industry is at the root of the problem
Senior NCO in the fight against entropy. I've seen things, man. Things no one should have to see.....
does not want these problems to be solved, they want to keep selling virus scanning software. Ensuring the encrypting guys fix their mistake works in Symantec's favour.
CAPTCHA: tyrant
It's in Symantec's interest that the authors mitigate the weakness in their malware so the threat will permeate through media and people will continue to be terrified into buying copious amounts of security software that in most cases won't even mitigate the risk.
I'd wager most of the encryption attacks bring their own encryption tools with them. Otherwise your target would be able to just block file encryption altogether and prevent the attack from working.
At first Symantec's actions sounded dismaying, but in the long run using every opportunity to publicize the folly of using that API is probably beneficial. I've spent years trying to dissuade people from using (old) Excel's password "protection" due to the false sense of security. That Win API has the same effect—convinces the masses they're employing secure means when in fact they're not.
The so-called security industry is big part of the problem.
While they continue to peddle their snake oil and sticking plaster solutions that the underlying problem. Microsoft and company will continue to peddle insecure crap ware.
kinda off topic but I saw some fake law enforcement /FBI popup that asks for a money order on my browser. I couldn't close Google Chrome normally. I ended up using the Windows task manager to terminate the process.
Not sure how the browser loaded the website. I even scaned the PC for viruses and malware.
They can't keep up with the known threats

Outmaneuvered at Their Own Game, Antivirus Makers Struggle to Adapt
Conventional security software is powerless against sophisticated attacks like Flame, but alternative approaches are only just getting started.
Some of them even get it, Eugene Kaspersky admits :
The contemporary antivirus industry and its problems
Symantec are the dumbest bunch of dumbfucks ever.
Combine that with shit software and the worst customer support in the business and the only conclusion is that Symantec can't die fast enough. Die Symantec, Die.
You can have my SIG when you pry it from my cold, dead hands.
One of the probably reasons they store the key on the box is because it's easier than having it on a remote server. A remote server can be taken out, unreachable, and you have the extra added problem of associating the decryption key with a specific box. That's a pain if the box isn't connected to the public network (i.e. it was infected through another vector).
If the key is local it's easier. You can even mail them a USB stick with the decryption application if you wanted to.
Future victims of this criminal organization should sue Symantec.
Class action lawsuit.
I also think that criminal charges for aiding and abetting would apply as well.

Okay, stupid question time...
If someone took a disk image during the time when the virus was in the process of encrypting files, would it be possible to find the key in the paging file?
This is excellent evidence to advocate shutting down bitcoin and all it's kin.
The only use of these 'currencies' seems to be criminal activity, and frankly, malware of this nature probably wouldn't even be feasible if it wasn't for bitcoin and it's kin. There'd be no way to anonymously extort money from victims.
Security through obscurity is a long-debunked myth. You people need to get over it - hiding an exploit only guarantees its continued effectiveness (obsecurity works both ways, protecting the exploit as well as the exploited). Exposing an exploit causes people to work to close the exploit and put it out of business. There's a short-term loss as every script-kiddie takes advantage of their newly discovered toy, but a greater long-term advantage in securing systems against said exploit.
To be sure, secrecy can be used to add to security - but the secret should be what you've done to close the holes, not the fact that those holes exist.
In Bitcoins! :D
Somebody (I assume with a personal agenda or an ax to grind) has downmodded a reasonably intelligent post.
Simple: What I can't touch, can't hurt me - Hosts do more w/ less (1 file) @ a faster level (ring 0) vs redundant browser addons (slowing up slower ring 3 browsers) via filtering 4 the IP stack (coded in C, loads w/ OS, & 1st net resolver queried w\ 45++ yrs.of optimization):

Summary:

A. ) Hosts do more than AdBlock ("souled-out" 2 Google/Crippled by default) + Ghostery (Advertiser owned) - "Fox guards henhouse", or Request Policy -> http://yro.slashdot.org/commen...
B. ) Hosts add reliability vs. downed or redirected DNS + secure vs. known malicious domains too -> http://tech.slashdot.org/comme... w/ less added "moving parts" complexity + room 4 breakdown,
C. ) Hosts files yield more speed (blocks ads & hardcodes fav sites - faster than remote DNS), security (vs. malicious domains serving mal-content + block spam/phish), reliability (vs. downed or Kaminsky redirect vulnerable DNS, 99% = unpatched vs. it & worst @ ISP level + weak vs FastFlux + DynDNS botnets), & anonymity (vs. dns request logs + DNSBL's).

* Addons are more complex + slowup browsers in message passing (use a few concurrently - you'll see) - Addons slowdown SLOWER usermode browsers layering on MORE: I work w/ what you have in kernelmode, via hosts ( A tightly integrated PART of the IP stack itself )
