French Researchers Find Last-ditch Cure To Unlock WannaCry Files (reuters.com)
French researchers said on Friday they had found a last-chance way for technicians to save Windows files encrypted by WannaCry, racing against a deadline as the ransomware threatens to start locking up victims' computers first infected a week ago. From a report: WannaCry, which started to sweep round the globe last Friday and has infected more than 300,000 computers in 150 nations, threatens to lock out victims who have not paid a sum of $300 to $600 within one week of infection. A loose-knit team of security researchers scattered across the globe said they had collaborated to develop a workaround to unlock the encryption key for files hit in the global attack, which several independent security researchers have confirmed. The researchers warned that their solution would only work in certain conditions, namely if computers had not been rebooted since becoming infected and if victims applied the fix before WannaCry carried out its threat to lock their files permanently.

From TFA:
"This is not a perfect solution," Suiche said. "But this is so far the only workable solution to help enterprises to recover their files if they have been infected and have no back-ups"
If an "enterprise" didn't already have a backup solution in place, their CIO - and relevant members of their IT staff - should be fired.

No, I'm afraid this is an instance of the American's surrendering and the French fighting. In other words, this reflects more of reality as America fails at not just its international obligations but even its intra-national ones. In contrast France actively fights terrorist groups in Mali and Niger so that they don't link in Nigeria and create a greater problem for the western world.
Topically, this is a sign of the strength of the French university system superseding the American system in one of the most important fields for future security.
"If computers had not been rebooted since becoming infected" -- It's a Windows computer. It's been rebooted LOTS of times, if just to install the Windows Updates pushed out by Microsoft.
They are toast.

This one is a backup in case the first one gets encrypted!
More to point: the old method worked only for WinXP, this one also for Win7.

P.S.=> For a SINGLE 'standalone' non-networked PC (no home network/LAN but TCP/IP connected online) turn off Server & Workstation services.
That shuts off any "handles" (port 445) this thing propogates thru + turn off NetBIOS over TCP/IP in your internet connection & uncheck/disable Client for Microsoft Networks + File and Print Sharing. Port 139 & 445 always pop up issues over time. It also makes your packet trains smaller (no encapsulation of LanMan)
I covered all this 11++ yrs. ago in a security guide I wrote for users with a single system & apparently, its advice STILL STANDS THE "TEST OF TIME" https://www.google.com/search?hl=en&source=hp&biw=&bih=&q=%22HOW+TO+SECURE+Windows+2000%2FXP%22&btnG=Google+Search&gbv=1/ vs. even today's threats like this one.
* This effectively makes this threat a non-issue + saves you CPU cycles/RAM & other I/O wasted on services you don't NEED as a single PC user only... & you don't. They're just wastes with a single PC really. Many services are (covered in guide above based on CIS Tool guidance (who took fixes to their ware from "yours truly" too, no less)) & again, no more encapsulated packet bulk.
AND?
Don't be STUPID & click on attachments in bogus malicious emails this thing propogates thru also (Chrome/Opera/Webkit users - BEWARE of the ShellControlFile issue that just popped up (.scf file) noted here-> http://www.theregister.co.uk/2017/05/17/chrome_on_windows_has_credential_theft_bug/ ) ... apk
'if the computer hasn't been rebooted since the infection'.
If it has been a week since infection, that has long since passed, I would say the first thing someone would do on seeing this is try to reboot. I would guess there is a flag the ransomware sets somewhere that tells it the machine has been restarted, I would say the chances of this are almost zero, knowing that most users reboot windows anyway to 'fix' most problems, or that it is the standard desktop support answer for most problems, having been on the receiving end of support occasionally.
All signs point to this being another attempt by Microsoft to get people to upgrade to Windows 10, not an actual piece of malware to produce money from the malware itself.
agreed
I'm German you fucking idiot - go troll somewhere else. Look up, I replied to the idiocy of another poster with information from reality. If you consider that a problem then perhaps you need some mental health treatment. Reality isn't flexible, and it is what it is.
Just for kicks last weekend I put a completely unpatched Windows 10 machine, installed from a June 2016 RTM, on the Internet, 100% exposed. No NAT firewall. No Windows Firewall. No AV. No anti-malware. No nothing. Public IP. I even went so far as to enable insecure RDP and install a VNC server with NO authentication on the standard port.
Almost a week later, there is nothing unusual happening on that machine. No unusual network traffic (almost none at all, actually). File checksums for all windows components are still the same. No new DLLs on the system. No record of anyone even connecting to the completely open and unprotected VNC server.
I figured after the scary story about Windows machines being infected by WannaCry in MINUTES, I could have some fun with it. But no. This machine is still sitting there perfectly fine. None of the random documents I put on it have been encrypted. No signs of infection by anything.
Sad!
... I see that /. has now added a link to that earlier /. story to the summary.

No, I'm afraid that the reason the US did not come up with a solution is because it is illegal under the DMCA. They could be sued by the perpetrators for bypassing encryption.

You aren't entirely wrong but I think it's important to remember that the US was hit very hard by this virus. There is no glory to be had and no incentive to continue working on the problem.
In contrast France actively fights terrorist groups in Mali and Niger so that they don't link in Nigeria and create a greater problem for the western world.
I think it's hilarious that you think we aren't doing enough to fight terrorism because we've practically destroyed ourselves with the level of military investment we've made just to kill some jerks in caves.

FTFY

But not in the Paris banlieues.
Regardless this is still a sign of the US isolationism causing it to fall in status and capability despite the growing need for information security response. Expense and effectiveness are different things. The French mission in Mali has succeeded through well organized management and brought greater stability and safety to the region. It started 4 years ago and continues even now as a unilateral mission, and the French have a military budget less than 2% of their GDP. That article is about the need to increase it to 2% over a few years. With much smaller budget France maintains its own nuclear powered aircraft carrier, nuclear arsenal, and expeditionary military force fighting across multiple fronts and producing measurable gains. Largely this is through ferreting all corruption out of military procurement, and if similar efforts are made then the US could achieve comparable results for cost and do more with the same budget.
Accusing a person of something he didn't say.
Claiming that he offers no solutions where actually the entire post was about an example which could be followed.
Accusing the person of affecting all humanity right after suggesting he only hates Americans for talking up someone else.
Claiming to have a false sense for sorrow for reasons unknown.
Accusing a foreigner that it's their fault for Trump being in office.
Then claiming you made a point.
Actually you made 5 points. None of them made sense.
One more point. You claim we think you're a "hater" when in fact the correct word would probably be "stoner". Lay off the weed when posting on slashdot man.
Wait what? Fixed That For Who? :-)

I agree completely. However, I think that our money would be better spent raising the standard of living and education globally than eternally fighting a small number of people. People don't get sucked into murdering others when their life is great and the future is hopeful. If you think it's an intrinsic part of the religion itself then you are an advocate for genocide.

It seems there are a large number of security researches. How do they make money, for examining malware day in and day out for a majority of their time ? Take the people mentioned in the article they are spending weeks and yet they will make nothing from their public service. After all this is over who will need or hire them ?
He just needs a Snickers.
The victims might be watching the timer, but the researchers can change the BIOS clock and create backups for their research.
