Cybersecurity researchers at Symantec Corp. and FireEye Inc. have uncovered more evidence tying this month's WannaCry global ransomware attacks to North Korea.
The cyberattack that infected hundreds of thousands of computers worldwide was "highly likely" to have originated with Lazarus, a hacking group linked to the reclusive state, Symantec said. The software used was virtually identical to versions employed in attacks earlier this year attributed to the same agency, the company said in a report late Monday. FireEye on Tuesday agreed WannaCry shared unique code with malware previously linked to North Korea. "The shared code likely means that, at a minimum, WannaCry operators share software development resources with North Korean espionage operators," Ben Read, a FireEye analyst, said in an emailed statement.
[...] The initial attack was stifled when a security researcher disabled a key mechanism used by the worm to spread, but experts said the hackers were likely to mount a second attack because so many users of personal computers with Microsoft operating systems couldn't or didn't download a security patch released in March labeled "critical."

WannaCrypt Ransomware Variant -- Lacking Kill Switch -- Seen in Wild [Updated]
Decryption Utility for WannaCry is Released
According to an article on DarkReading.com, ransomware will remain king in 2017.
2016 was the year of ransomware, with hackers focusing their attentions on exploiting Internet users and businesses around the world for profit. According to the FBI, cyber-extortion losses have skyrocketed, and ransomware was on track to become a $1 billion a year crime in 2016.
Our research shows no sign of this security nightmare slowing down in 2017. Hackers are becoming more advanced, and ransomware remains an incredibly easy, lucrative way for them to make money. Unfortunately, the security community has only started to develop defenses that can protect Internet users from ransomware.
With the new year around the corner, security researchers at Malwarebytes Labs have compiled a list of predictions for new ransomware threats, developments, and opportunities that they expect consumers and businesses will face in 2017.
NSA-created cyber tool spawns global ransomware attacks
Leaked alleged NSA hacking tools appear to be behind a massive cyberattack disrupting hospitals and companies across Europe, Asia and the U.S., with Russia among the hardest-hit countries.
The unique malware causing the attacks - which has spread to tens of thousands of companies in 99 countries, according to the cyber firm Avast - have forced some hospitals to stop admitting new patients with serious medical conditions and driven other companies to shut down their networks, leaving valuable files unavailable.
The source of the world-wide digital assault seems to be a version of an apparent NSA-created hacking tool that was dumped online in April by a group calling itself the Shadow Brokers. The tool, a type of ransomware, locks up a company's networks and holds files and data hostage until a fee is paid. Researchers said the malware is exploiting a Microsoft software flaw.
One or more anti-virus companies may have been hacked prior to WannaCrypt infecting 75000 Microsoft Windows computers in 99 countries. First, anti-virus software like Avast fails to make HTTP connections. Second, five million of ransomware emails are rapidly sent. Although many centralized email servers were able to stem the onslaught, many instances of anti-virus software had outdated virus definitions and were defenseless against the attack. Indeed, successful attacks were above 1%. Of these, more than 1% have already paid the ransom. Although various governments have rules (or laws) against paying ransom, it is possible that ransoms have been paid to regain access to some systems.
Also, file scrambling ransomware has similarities to REAMDE by Neal Stephenson. Although the book is extremely badly written, its scenarios (offline and online) seem to come true with forceful regularity.
Telefónica reportedly affected. NHS failed to patch computers which affected US hospitals in 2016. 16 divisions of the UK's NHS taken offline with aid of NSA Fuzzbunch exploit. The fun of a public blockchain is that ransom payments of £415,000 have been confirmed. Cancellation of heart surgery confirmed. Doctors unable to check allergies or prescribe medication. Patient access to emergency treatment denied in part due to hospital telephone exchange being offline.
It also appears that one of the affected parties refused to answer a Freedom of Information request in Nov 2016 about cyber-security due to impact on crime detection. Similar parties provided responses to the same request.
[Update at 20170515_022452 UTC: Instructions for what to do on each affected version of Windows can be found at: https://www.askwoody.com/2017/how-to-make-sure-you-wont-get-hit-by-wannacrywannacrypt/ -- I've had excellent luck in the past following his advice on when and how to update Windows. Clear, hands-on instructions are a big win in my book. --martyb]
tl;dr: If you have not already patched your Windows computer(s), you may be at risk from a new variant of the WannaCrypt ransomware worm which lacks a kill switch and was seen over the weekend. Sysadmins are preparing for a busy Monday when countless other users return to work and boot up their PC.
WannaCrypt (aka WCry), is a ransomware worm that wreaked havoc across the internet this past weekend. It disabled Windows computers at hospitals, telecoms, FedEx, and banks (among many others). Files on user's machines were encrypted and the worm demanded $300 or $600 worth of Bitcoin to decrypt (depending on how quickly you responded). Reports first surfaced Friday night and were stopped only because a researcher discovered a domain name in the code, which when registered, caused the malware to stop infecting new machines.
We're not out of the woods on this one. Not surprisingly, a variant has been seen in the wild over the weekend which has removed the domain check. Just because you may not have been hit in the initial wave of attacks does not necessarily mean you are immune.
Back in March, Microsoft released updates to Windows to patch vaguely-described vulnerabilities. Approximately one month later, a dump of purported NSA (National Security Agency) hacking tools were posted to the web. The WannaCrypt ransomware appears to be based on one of those tools. Surprisingly, the Microsoft patches blocked the vulnerability that was employed by WannaCrypt.
In a surprising move, Microsoft has just released emergency patches for out-of-mainstream-support versions of Windows (XP, 8, and Server 2003) to address this vulnerability.
Sources: Our previous coverage linked above as well as reports from the BBC Ransomware cyber-attack threat escalating - Europol, Motherboard Round Two: WannaCrypt Ransomware That Struck the Globe Is Back, and Ars Technica WCry is so mean Microsoft issues patch for 3 unsupported Windows versions.
What actions, if any, have you taken to protect your Windows machine(s) from this threat? How up-to-date are your backups? Have you tested them? If you are a sysadmin, how concerned are you about what you will be facing at work on Monday?
Various news outlets report the release of
Wannakey, a decryption utility for files encrypted by the WannaCry ransomware. According to the author of the software, it "has only been tested and known to work under Windows XP."
From the Wired article noted below:
Now one French researcher says he's found at least a hint of a very limited remedy. The fix still seems too buggy, and far from the panacea WannaCry victims have hoped for. But if Adrien Guinet's claims hold up, his tool could unlock some infected computers running Windows XP, the aging, largely unsupported version of Microsoft's operating system, which analysts believe accounts for some portion of the WannaCry plague.
[...] Guinet says he's successfully used the decryption tool several times on test XP machines he's infected with WannaCry. But he cautions that, because those traces are stored in volatile memory, the trick fails if the malware or any other process happened to overwrite the lingering decryption key, or if the computer rebooted any time after infection.
A report suggests that North Korean hackers are looking for money to steal as harsher sanctions are implemented against the country:
North Korean hackers are increasingly trying to steal cash rather than secrets, a South Korean government-backed report suggests. Cyber-criminals are targeting financial institutions as Pyongyang faces tough nuclear sanctions, the Financial Security Institute (FSI) claims. Suspected hacking attempts were until recently thought to be aimed at causing disruption or accessing data.
North Korea has routinely denied involvement in cyber-attacks. The FSI analysed cyber-attacks between 2015 and 2017. The impoverished country is now facing even tougher international sanctions aimed at stopping the flow of money that would support the development of its weapons programme.
Attacks cited include the "WannaCry" ransomware attacks, an attack on the Bangladeshi central bank, attacks by a group called "Andariel", and the 2015 attacks against South Korean banks that led to the formation of the Financial Security Institute.
A derivative of Microsoft Windows ransonware, Wannacry, has hit a Boeing production plant in Charleston, South Carolina. An internal memo from Mike VanderWel, chief engineer of Boeing Commercial Airplane production engineering, warned that the company's production systems and airline software were "at risk".
Wannacry was based on Microsoft Windows' CVE 2017-0144 which is used in the EternalBlue exploit kit. EternalBlue was initially utilized in apparent coordination with Microsoft's long delay in patching. Despite massive media spin, Wannacry was found to have hit all recent versions of Microsoft Windows.
