Razer is a very popular computer peripherals manufacturer that designs, develops, and sells consumer electronics, financial services, and gaming hardware, including gaming mouses and keyboards. Upon plugging in a Razer device into Windows 10 or Windows 11, the operating system will automatically download and install the Razer Synapse driver and the Razer Synapse software on the computer that allows configuring the devices. The flaw was discovered by the security researcher jonhat that disclosed it via Twitter:. Need local admin and have physical access? So here's a freebie pic. The expert decided to publicly disclose the issue because he did not receive a response from Razer, he also published a video PoC of the attack:.

Security Risks in Zero Knowledge Proof Cryptocurrencies

This screenshot is just one example: The IT systems of around 40 National Health System hospitals across the UK were affected by this ransomware attack. Non-emergency operations have been suspended and ambulances are being diverted as a result of the infection.

Cybersecurity experts have long used the phrase " where bits and bytes meet flesh and blood," which signifies a cyberattack in which someone is physically harmed. M ikko Hypponen, chief research officer at the Helsinki-based cybersecurity company F-Secure, called the attack "the biggest ransomware outbreak in history.

In the Jan 3 issue of CyberheistNews, we predicted that would be the year where we'd see a ransomworm like this. Unfortunately, it's here. I suggest you send the following to your employees, friends, and family. You may have seen the news this weekend. Criminal hackers have released a new strain of ransomware that spreads itself automatically across all workstations in a network, causing a global epidemic.

If you or a co-worker are not paying attention and accidentally open one of these phishing email attachments, you might infect not only your own workstation, but immediately everyone else's computer too.

Be very careful when you get an email with an attachment you did not ask for. If there is a. Remember: "When in doubt, throw it out! Optional if you use the free KnowBe4 Phish Alert Button : When you see a suspicious email, click on the Phish Alert Button, which forwards this email to the IT team and safely deletes it at the same time.

The source is Kaspersky's Securelist , note that this is just the early days, and their visibility is likely limited. This monster has infected hundreds of thousands of systems in more than countries. Monday morning when people get back to work, these numbers will only go up. Check out an early animated map created by the NYTimes. Here is an infection map based on data from MalwareTech. Bleepingcomputer said: "Whoever is behind this ransomware has invested heavy resources into Wana Decrypt0r's operations.

In the few hours this ransomware has been active, it has made many high-profile victims all over the world. Despite the fact that this strain is hyper-aggressive, the criminals behind the code do not seem to be all that sophisticated, they are using only a limited amount of static bitcoin wallets. Could even be that they are relative newbies at ransomware, and that the NSA worm-code has run amok scaring the daylight out them, afraid to be caught. The Ransom Deadline Is Short. If you don't pay within a week then the ransomware threatens to delete the files altogether.

Note the social engineering aspect here too: a sense of urgency is created to prompt people into action. A sense of hope is granted by virtue of the ability to decrypt a sample selection of the files. As everybody keeps calling it "Wana Decrypt0r," this is the name we'll use in this article, but all are the same thing, which is version 2.

Kaspersky Lab also reports that the Wana strain has numerous languages available and was designed to affect multiple countries. According to CrowdStrike's vice president of intelligence Adam Meyers, the initial spread of WannaCry is coming through phishing , in which fake invoices, job offers and other lures are being sent out to random email addresses. Within the emails is a password protected. Microsoft confirms this in a blog post. But the most concerning aspect of WannaCry is its use of the worm-like EternalBlue exploit.

It's widespread. Department of Homeland Security said in a statement released late Friday. After the initial infection, the malware spreads like a worm via SMB, that is the Server Message Block protocol used by Windows machines to communicate with file systems over a network. The file tasksche. The malware then checks for files with a file extension as listed in the appendix and encrypts these using bit RSA encryption.

From what we have been able to learn, Wana spreads through SMB so when we're talking about machines behind firewalls being impacted, it implies ports and being open and at-risk hosts listening to inbound connections. It'd only take one machine behind the firewall to become infected to then put all other workstations and servers at risk due to it being a true worm. In the meantime, harden yourselves against this Windows Network Share vulnerability and ensure that all systems are fully patched with the "MS" security update link below and remind all staff to Think Before They Click when they receive any out of the ordinary emails.

Note, the patch is included in the Monthly Quality rollups. Spent a panicky 10 minutes when I saw the article looking for Security update on my PC and then on our WSUS server only to discover that it is included in - Besides installing these out-of-band updates — available for download from here — Microsoft also advises companies and users to outright disable the SMBv1 protocol , as it's an old and outdated protocol, already superseded by newer versions, such as SMBv2 and SMBv3.

Y ou can use Group Policy for Clients and Servers. Here is a script to check the complete Active Directory for systems that miss the WannaCry related hotfixes. According to an experiment carried out by a French security researcher that goes online by the name of Benkow. WannaCry infected the honeypot in a mere three minutes after it was reset, showing the aggressive nature of the ransomware's scanning module, which helps it spread to new victims. Noteworthy: three minutes is about the same amount of time IoT malware will infect a vulnerable home router left connected to the Internet without patches.

This will give you access to flows and packet payloads so you can see who is connecting to what and if there is anything suspicious moving around. Check out this blog post if you use Cisco switches, it explains how you can monitor multiple network segments without the need to remember what is connected to what switch port.

There is one caveat though, this infection moves out like lightning from patient zero, and all vulnerable machines are literally locked in less than two minutes so monitoring alone would not be enough to be stop this monster. Here is a video showing a machine on the left infected with MS worm, spreading WCry ransomware to machine on the right in real time. This ransomware strain cannot be decrypted with free tools. R esearch shows the encryption is done with RSA encryption. That means that decryption will be next to impossible, unless the coders have made a mistake that has not been found yet.

Your best bet is to recover from backups, and if your backup failed or does not exist, try a program like Shadow Explorer to see if the ransomware did not properly delete your Shadow Volume Copies.

If a user did not click Yes at the UAC prompt, then there is a chance those are still available to start the recovery. Here is How to recover files and folders using Shadow Volume Copies. As a last resort and all backups have failed, you could decide to pay and get the files decrypted. It appears to work. It's possible but difficult. Some bitcoin has reportedly been paid into hackers' accounts and investigators can track the money and see where the bitcoin ends up. H owever, hackers are still able to hide and launder the bitcoins in many different ways.

Investigators will also examine the code itself as hackers often leave identifiable traces of their work. You can watch as some of these wallets are receiving money in real time. There is an international manhunt underway. Cisco Talos has confirmed the information. However, this is just a temporary deterrent.

For the bad guys, it's just one line of code to fix this and the infection process starts again. You can hope that your endpoint protection blocks it, but do not count on that. The way to prevent this infection is the 8 steps above, and of course it helps to have your users trained within an inch of their lives to spot phishing red flags.

Round Two: WannaCry Is back. As expected, that was only a temporary fix. Over Friday and Saturday, samples of the malware emerged without the kill switch, meaning that attackers have resumed their campaign even though the MalwareTech security researcher accidentally cut off the original wave. However, there seems to be some controversy if the new version uses the NSA worm or not. I say better be safe than sorry, because there will be copycats.

This attack has hit the press internationally. China states more than a million machines were affected. Pundits are now pointing at Microsoft's code, who in turn point at the NSA for allowing this out of the bottle. Of course Snowden blames the NSA as well. And then there is victim blaming, because auto-updates were turned off which would have fixed this 2 months ago. Enough blame to go around for everyone. Ultimately this is a shared responsibility, but IT people are carrying the heavy load here and often do not get enough budget to get the job done right.

Predictions are the infection is going to get worse, because now machines will be turned on that aren't patched, like MRI machines in hospitals and other medical devices that still run XP and have not been patched.

A North Korean hacking group is suspected to be behind WannaCry. The companies claim to have found some code in an earlier version of the WCry ransomware that had also been used in programs deployed by the Lazarus Group, which is reportedly run by the Hermit Kingdom.

Symantec has determined that this shared code is a form of SSL. This SSL implementation uses a specific sequence of 75 ciphers which to date have only been seen across Lazarus tools including Contopee and Brambul and WannaCry variants. Despite earlier confirmations from several sources , it looks that phishing is not the primary infection vector.

An employee could have taken a business laptop to a coffee shop or hotel and logged onto their insecure Wi-FI without using a VPN and a hacker could have slipped WannaCry onto the device. When the employee brought the laptop back to the office and connected it to the network, WannaCry would get inside the network, spreading itself via port More important, it also appears the first infections were in south-east Asia which points to North Korea as a possible culprit.

Researchers assumed early on that the outbreak began with an email link or attachment, but SophosLabs VP Simon Reed said this looks like a worm from start to finish:. There were no outlook. In other words, this outbreak was a throwback to those of the early s.

Only this time, instead of mere noise and network downtime, a much more damaging payload of ransomware ground many organizations to a halt. As expected, The WannaCry ransomware attack that took out the United Kingdom healthcare service also hit at least two Bayer medical devices in the U. An image received by the business magazine shows the now-familiar WannaCry ransom message obscuring the display of a Bayer radiology system.

Hackers return nearly half of the $600 million they stole in one of the biggest crypto heists

In this week's feature interview we're chatting with Dave Jorm, our resident North Korea watcher. Some of you might remember Dave, he was on the show a couple of years ago talking about his OSINT satellite data analysis of North Korea and more recently he popped by to talk about software defined networking security. Well, some recent analysis of North Korea's official Red Star OS has found it has a nasty habit -- it watermarks media files that users open with a unique ID. This will of course help the North Korean regime to track down the smugglers of digital media, whether that's activist material or South Korean soaps, which are most definitely verboten in the hermit kingdom. This week's show is brought to you by Intralinks -- these guys do secure document exchange and storage. Intralinks very own Todd Partridge drops by to talk about how their customers are actually customising these types of document services.

If you have time or struggle to understand anything I highly recommend checking out the slides and watching the video. I also recommend our free interactive CORS labs. It's frequently used by web APIs in particular, but in a modern complex website it can turn up anywhere. The server can enable credential transmission using the following header:. This creates a trust relationship - an XSS vulnerability on example. Trusting a single origin is easy. What if you need to trust multiple origins?

How To Detect And Mitigate Zero-Day Attacks

A zero-day attack also referred to as Day Zero is an attack that exploits a potentially serious software security weakness that the vendor or developer may be unaware of. The software developer must rush to resolve the weakness as soon as it is discovered in order to limit the threat to software users. The solution is called a software patch. Zero-day attacks can also be used to attack the internet of things IoT. A zero-day attack gets its name from the number of days the software developer has known about the problem.

By John Martineau. Category: Ransomware , Unit While REvil which is also known as Sodinokibi may seem like a new player in the world of cybercrime, Unit 42 has been monitoring the threat actors tied to this group for three years. We first encountered them in when they were working with a group known as GandCrab. At the time, they were mostly focused on distributing ransomware through malvertising and exploit kits, which are malicious advertisements and malware tools that hackers use to infect victims through drive-by downloads when they visit a malicious website.

There has been another reported incident of a hacker selling stolen personal information on the dark web. There are four databases on offer, which includes patient details such as names, addresses, dates of birth, social security numbers, and health insurance information. The largest batch, containing over 9. Motherboard was provided with a sample of records from the Georgia database. The vast majority of phone numbers connected to the correct person, and one individual confirmed that their details were correct.

Yesterday, we wrote about a vaguely mysterious zero-day patch pushed out by Apple. An additional patch, watchOS 7. Was the new bug the secret heart of a new jailbreak that got leaked to Apple ahead of time? Was it an exploit built for a cybercrime attack that never took place? That statement has a fair amount of distance in it: not that it was exploited, but that it may have been; and not first-hand experience but merely awareness of a report about it. Of course, none of that really matters given that Apple made it clear that this was a dangerous vulnerability a likely code execution hole with kernel privileges , and pushed out patch to fix it.
