Suggested December 2023 What You Need To Know About Osx/Dok Malware
A new type of man-in-the-middle attack has been detected in the wild, targeting Apple’s Mac. Dubbed OSX/DOK, it relies on a new strain of macOS malware which leverages a bogus security certificate to bypass Apple’s Gatekeeper protection. Popular anti-virus programs are currently unable to detect OSX/DOK.
The Hacker News and researches at CheckPoint explain that the malware affects all versions of macOS by using a valid developer certificate signed by Apple. Here’s what OSX/DOK does, how it works, how to tell if you’re affected and what you can do to protect yourself and avoid these kinds of attacks in the future.What is OSX/DOK?
OSX/DOK is a new type of malware distributed via an email phishing campaign.
It’s been designed to specifically target Mac owners. OSX/DOK affects all macOS versions and can avoid detection by most anti-virus programs. It’s signed with a valid developer certificate authenticated by Apple, meaning it avoids detection by macOS’s Gatekeeper security feature.How does OSX/DOK infest your Mac?
The malware bundle is contained in a .ZIP archive named “Dokument.zip.”
Once executed, the malware first copies itself to your Mac’s /Users/Shared/ folder before executing itself from that location. It then proceeds to install a new root certificate which lets it intercept your traffic with a man-in-the-middle attack. To ensure the malware finishes installing its payload before a reboot, it adds itself as macOS Login Item named “AppStore”.
Next, the user is greeted with a persistent window designed to look like a valid macOS warning, as you’re seeing on the screenshot below. The window informs the user of a supposed security issue in their Mac which requires an update. The message prevents the user from doing anything on their computer until they accept the fake update prompt.
Once the password is supplied, the malware gains administrator privileges on your Mac.
Using those privileges, it installs command-line tools that allow connection to the dark web. It then changes your Network Settings to redirect all outgoing connections through a malicious proxy server which lets the attacker eavesdrop on your communications.
Some phishing messages used to spread the malware appear to mostly target users in Germany, but that doesn’t mean that only European users are at risk. For what it’s worth, the malware code supports messages in both German and English.What damage does OSX/DOK do?
OSX/Dok redirects your traffic via a malicious proxy server, giving nefarious users access to all your communication, including that encrypted by SSL. Because it installs a compromised root certificate on the system, the attacker is able to impersonate any website to fool users into providing their passwords for banking apps and popular online services.How to know if you’re affected?
If you’ve recently opened a ZIP file in an email message you weren’t expecting, and are now seeing suspicious-looking prompts asking for your Mac password, your system may have been infected with OS X/DOK. Because the malware redirects your network traffic to a rogue proxy server, you should venture into System Preferences → Network.
If Automatic Proxy Configuration has been enabled in the lefthand column and the field underneath the heading Proxy Configuration File points to the URL that begins with “127.0.0.1:5555”, the malware is already routing all your traffic through a rogue proxy server.
The malware installs two LaunchAgents that will start with system boot:
If you find these files in the above locations, delete them immediately.
If the certificate is installed on your Mac, delete it.How to protect yourself?
OSX/DOK is the first major-scale malware to target Mac users via a coordinated email phishing campaign.
The first point of attack relies on the user opening a maliciously-crafted attachment in an email message. Don’t open suspicious attachments, especially if the attached file is named “Dokument.ZIP”. Beware of phishing messages bearing animated GIFs or those regarding supposed inconsistencies in your tax returns.
Always check the headers to confirm the validity of the sender.
If the malware file has found its way on your system, do not interact with and suspicious-looking prompts pretending to be valid macOS dialogs, especially if they ask for your root password for no apparent reason. Apple never puts up warning messages if your Mac requires a software update. All macOS software updates are distributed exclusively via Mac App Store.
If you use an anti-virus app, update its signature database manually.
At the time of this writing, no anti-virus vendor has updated their signature database with DOK OS X malware, but that will change soon. This malware issue will be fully resolved as soon as Apple revokes the bogus security certificate that its author has abused to bypass the Gatekeeper security feature.

What is web3? What do you need to know about web3 technology? Its features and layers
Web 3 or Web 3.0 has the potential to be disruptive and usher in a significant paradigm shift like Web 2.0 did. Web 3 is formed due to the fundamental ideas of decentralization, increased consumer usefulness, and openness. Web 3 technology plays the next step in the development of the internet.
Web 3 accurately translates and understands what you type through text, voice, or other media. The technology also understands what you say. In this article, we have discussed what is web3 and what all you need to know about web3 including its features of web3. Read to know about web3 technology.What Is Web 3.0 Technology?
Web 3.0 or Web 3 is a third-generation world wide web built on top of blockchain developments and technologies in the Semantic Web. Web 3 is meant to be decentralized, and open to everyone which describes the web as a network of meaningfully linked data.Key Features of Web3
Web3 has several distinguished features.
Decentralization: In web 2.0 computers search for the data that is kept at a fixed location mostly in a single server using HTTP in form of a web address. Information could be stored in multiple locations at the same time and become decentralized with Web 3.0 because it would be found based on its content rather than a single location. This would give people more power by destroying the massive databases that internet behemoths like Meta and Google currently maintain.
With the help of web 3, users will be able to sell their data through decentralized data networks, ensuring that they retain control of their ownership. This information will be generated by a wide range of powerful computing resources, including mobile phones, desktop computers, appliances, automobiles, and sensors.
Decentralization and open-source software-based Web 3.0 will also be trustless (i.e., participants will be able to interact directly without going through a trusted intermediary) and permissionless (each individual will be able to access without the permission of any governing body). This means that Web 3.0 applications, also known as dApps, will run on blockchains, decentralized peer-to-peer networks, or a hybrid of the two. DApps are decentralized apps.
Connectivity and ubiquity: With Web 3.0, content and information are more accessible across applications and an increasing number of commonplace internet-connected devices.How Does Web 3 Work?
Your data is saved in web3 on your cryptocurrency notecase. On web3, you’ll interact with apps and communities via your wallet, and when you log out, your data will follow you. Because you own the data, you can theoretically decide whether to monetize it.
After we’ve established our guiding principles, we can look at how specific web3 development features are supposed to achieve these goals.Data Ownership:
When you use a platform such as Facebook or YouTube, these companies collect, own, and recoup your data. Your information is saved in web3 on your cryptocurrency wallet. On web3, you’ll interact with apps and communities via your wallet, and when you log out, your data will follow you. Because you own the data, you can theoretically decide whether to monetize it.Pseudonymity:
Privacy, like data ownership, is a feature of your wallet. On web3, your wallet serves as your identification, making it difficult to link it to your actual identity. As a result, even if someone observes wallet activity, they will not be able to identify your wallet.
Some services of web 3 assist customers in connecting to cryptocurrency wallets used for illegal activity.
Although wallets improve the level of privacy for bitcoin transactions, privacy coins such as Zcash and Monero provide complete anonymity. Observers can track transactions on blockchains for privacy coins, but they cannot see the wallets involved.
Giving a factory tour to your clients or investors can be just what you need to build a closer relationship with them. Once your visitors see where your products are made and meet your staff, your company will no longer be another faceless corporation. Thanks to that, they’ll be more inclined to stay loyal to your brand.
But a disorganized, unprofessional company tour can hurt your reputation far more than help it. And in a noisy, chaotic environment such as your factory, things can go wrong rather quickly. One of the biggest issues you’ll face is ensuring your visitors hear the presentation they came for.What Exactly Is a Tour Guide System?
A tour guide system is a network of devices whose main purpose is to make communication in high-noise environments easier. Those devices typically include:
Charging stations or cases. Since the devices we mentioned are portable and wireless, they rely on batteries to power them. Obviously, those batteries need charging, which is why charging stations are necessary. They often come in the form of a case, allowing you to store your equipment and charge it at the same time.
Aside from these units that every tour guide system must have, there are more complex kinds with additional functionalities. For instance, some communication systems offer simultaneous translation, noise reduction and canceling, and volume control. Thanks to that, they can have various applications — factory and plant tours, audio services for the visually impaired, and translation services during an international conference, just to name a few.Types of Tour Guide Systems
Typically, you’ll encounter two types of tour guide systems on the market. Those are one-way systems and two-way systems. Each has its own applications, benefits, and drawbacks, so think carefully before deciding which one is right for you.
How Does a Tour Guide System Work?
After finding out what devices it includes and what it’s used for, there’s one thing you still may be wondering — how does a tour guide system work, exactly? Luckily, we’re here to resolve that mystery and give you a quick rundown.
Once you turn on your wireless equipment, all units are connected to one another using the so-called MHz frequency bands. These bands are used for radio, television, and other terrestrial broadcasting, and they allow for quick and easy transmission of voice. Thanks to them, there’s no need for wires of any kind — you just need to set up your devices so they are on the same frequency.
After that, there’s nothing to worry about. Simply speak into your microphone as you take your guests on tour. As long as they’re within range, they’ll hear you as if you were standing right next to them. The noise-reducing feature will ensure no background noise drowns out your voice, yet at the same time, you won’t be entirely deaf to your surroundings. And that’s essential in a potentially dangerous environment that a factory can be — you want to be ready to respond to any warning or commotion.
Other Applications a Tour Guide System Can Have in Your Factory
Tour guide systems are excellent for factory tours, but that’s not their only application. In fact, even within your company, there are still a few more uses you can find for them. For example:
Use them when training your future employees and showing them around their new workplaces.
Give them to factory workers so they can interact without shouting and straining their voices.
Have walking meetings and conferences in the factory without having to stop any activities or production.
If you’ve been thinking of getting a tour guide system for your factory tours and other needs, don’t hesitate. Now you have enough information to understand why you should have one and what it entails. So go ahead — we’re sure you won’t regret it.Rick Farrell

Indian Point Energy Center, an aging nuclear power plant located just 25 miles away from New York City, recently detected elevated amounts of radiation in groundwater near the plant, according to news alerts published on Saturday by the facility’s parent company Entergy and by New York Governor Andrew Cuomo.
It sounds scary, and in some ways it is — figuring out how the radiation got into the groundwater is a mystery that needs solving. But there isn’t any immediate danger to public health.
Gov. Cuomo’s statement tried to strike a balance between concern and reassurance:
He also said he directed the New York Commissioners of Environmental Conservation and Health to begin an investigation into the incident.
Tritium is a radioactive isotope of hydrogen. It’s present in the environment naturally in very small amounts, but can also be created by nuclear power plants. It can’t travel very far in air, but it can combine with oxygen to create water, just like normal hydrogen. This resulting water is called tritiated water, and can mix with regular water easily. That’s what was found in the monitoring wells at Indian Point.
The water in the wells isn’t used for drinking, but even if it was, tritiated water isn’t considered a huge health concern, especially in extremely low doses. Because it acts just like other forms of water: it goes into soft tissues, and is generally expelled from the body quickly, in a matter of days.
That doesn’t mean that people aren’t paying attention to the issue. Nuclear power plants aren’t supposed to leak. Even if they aren’t leaking glowing green sludge, it’s something that people want to monitor. But tritium leaks happen more often than you might think. Of the 65 nuclear power plants (past and present) in the United States, 46 have reported tritium leaks into groundwater in excess of the 20,000 picocurie per liter limit set by the EPA as the safe amount in drinking water. There are 13 total power plants that are currently reporting levels of tritium larger than the EPA limit, but none have detected that amount in any drinking water.
A picocurie is one-trillionth of a Curie, a measure of radioactivity. For comparison, a routine thyroid test uses about one millionth of a curie, a much larger dose.
The cause for the urgency at Indian Point is that the amount of tritium in the water suddenly increased, jumping from 12,300 picocuries per liter, to over 8 million picocuries per liter. Again, that isn’t in any drinking water supplies, and hasn’t been detected outside of the power plant property. But given that water generally doesn’t observe property boundaries or “no trespassing” signs, the plant managers and government officials do need to be keeping an eye on the situation.
The Indian Point power plant has two currently operating nuclear reactors, which went online in 1974 and 1976 respectively. They provide 25 percent of all the power used in New York City and Westchester county. To give a sense of scale, a total of 9.37 million people live in New York City and Westchester combined.
Another nuclear reactor at the Indian Point site operated from 1962 to 1974 before being shut down due to a cooling system that didn’t meet regulatory standards. In the past, leaks of tritium and strontium-90 into the groundwater have both been traced to this now-defunct reactor. Spent fuel was removed from the reactor forty years ago in 1976, but Entergy is still monitoring the building near where the spent fuel was stored.
After making the crowd go WOW for a few minutes, Steve-o, loyal to himself, started the presentation about iPhone OS 4.
Here is everything you need to know about iPhone OS 4 (all images are compliments of gdgt):
iPhone OS 4, will come with many many new features. With over 1,500 new APIs for devs, chances are there will be a little something for everyone.
Although iPhone OS 4 will come with hundreds of new features, the presentation was focused on 7 of them.1. Multitasking
This is a given one that I had predicted since last year (hey no applause for me here, please hehe). As steve Jobs said, “We weren’t the first to this party, but we’re going to be the best”, and I believe him.
Dudes from Pandora and Skype came up on stage and demo’d their apps in action, running in the background. If you’ve seen Backgrounder and Proswitcher, you won’t be amazed by that. I guess the real asset of Apple’s new multitasking is that it’s been developed to not feel sluggish or drain the battery, which you might have experienced with apps like Proswitcher.
Apple will be providing seven multitasking services:
Fast app switching2. Folders
Very much inspired from the jailbreak app Categories, Folders will give people the ability to organize their apps better.
Apple added a beautiful UI that allows you to drag and drop your apps in folders. The folder name is automatically created but can of course be edited. Up to OS 3.X, you were able to have 180 apps on your iPhone over 11 pages. If you replace every one of those with a folder, you’re now going to be able to see 2,160 apps!
3. Enhanced Mail
This is another big one that I’ve wanted to see for a while: the unified inbox.
You can now have all your emails from different accounts come in one unified inbox. Obviously, you can still switch to a specific inbox if you wish too. Additionally, iPhone OS 4 allows you to add multiple Exchange accounts (no more hack needed).
Finally, Apple added the ability to sort your emails by thread, pretty much like Gmail does.
This is one I really don’t care about. I guess many people do though, and that’s yet another opportunity for Apple to sell you something (ebooks).
Not much was said about iBooks. Basically they brought it from the iPad. Nothing exciting…
5. Enterprise Features
A bunch of features for companies that no one except businesses really care about. My favorite is wireless app distribution which allows a company to wirelessly distribute an application anywhere in the world with their own servers.6. Game Center
Again, nothing really groundbreaking here. Apple added a social gaming network that does automatic matchmaking, find others with a similar ability and match them against you.
This is the big fish of the day. While you probably won’t give a damn about iAd, let me tell you this: iAd is the reason why I bought a crap load of Apple stocks…
One thing I forgot to add in there is that you’ll now be able able to add custom backgrounds to your home screen. That’s not really the theming many of us expected, but that’s a start.
Apple will be releasing a developer preview of iPhone OS 4 today at chúng tôi
iPhone OS 4 will be release to the rest of us this summer for the iPhone 3GS and iPod Touch 3G. They will run pretty much everything. The iPhone 3G and iPod Touch 2G will run many of these new features, but not everything (ie. multitasking) because the hardware just can’t do it. iphone OS 4 won’t be released until this fall for the iPad.
All in all, I’m not impressed by this presentation as I expected much more from iPhone OS 4 but let’s not forget this is just a developer presentation and there is still a few months until the launch of the next iPhone. Like the teaser said, this was just a sneak peek at the future of iPhone OS. Something tells me there is much more to come in the next few months.
Thanks to gdgt for the amazing live blogging and for the images.
Are free press release websites worth using?
The question of whether to use free press release websites is a common one amongst many hands-on marketers trying to get a benefit for SEO and PR… Quickly followed by how many of these should we use and is it worth paying?What are Free PR websites?
Such websites exist as content hubs for press releases from all manner of business. View them as a press release repository. Usually organised by industry and sorted by features / date stamp these websites carried multiple benefits for marketeers :
A place to monitor activity in a particular industry
A vehicle to get content in-front of journalists and other such authors / influencers
A way to drive traffic to a website
A method of creating inbound links to your own site
However, there are now inherent problems with such websites as the report by Vitis PR highlights:
There are many of them so journalists couldn’t possibly look at them all even if they wanted to!
The content on many of them is no longer news worthy or relevant
They are often filled with spammy poor quality content
The links they generate are of little quality (Thanks Panda)
While this is a review and listing of over 60 sites, the Vitis report is useful in calling out the most useful sites. We contacted Vitis as part of writing this review and they said they will be updating the report, so watch this space.
Research finding 1. Only 5% of Free PR Sites will get you featured in Google NewsBest free press release site for Google News
Online PR News got three of our four releases on Google News. PR Fire only got one release onto Google News while Open PR got two of them there. Many, many others didn’t manage any.Research finding 2. Only half of sites are guaranteed to get the release in Google Search
Having brand content on outposts that not owned properties (your own site or your own Facebook etc) it is a fundamental part of content marketing. The more opportunities you can create to for your brand to appear in relevant places the better. This stat I have to say surprised me, the fact that some pr sites are not even indexed by Google I find fascinating. With this data in mind I would genuinely suggest you take a loo at the Google doc on the Vitis site to establish whether you are currently utilising some of these sites…Best free press release site for appearing in Google web searches
Appearing in web searches may be valuable as a way of trying to put your news in front of people searching for your target phrases – though it is unlikely this will be effective where the target phrases are more than moderately competitive.
Interestingly, of the three releases that PR Fire accepted, all three appeared on page one of Google search results for the phrases we searched on.Research Finding 3. 29% of sites generate followed inbound links
In the past (2+ years ago) press and article sites were valuable places to receive inbound links from, they showed a brand was active and the keywords used meant they were relevant for particular searches etc… This however due to the abuse of such channels is no longer the case, most article sites for example do not carry any credibility anymore so their links are almost worthless. While the % of sites that allow followed links is relatively high, the quality they carry is minimal so I wouldn’t, personally be distracted by these sites.Best free press release site for building links
Vitis say in their report: “Given that none of the releases was picked up by any site that might be considered to be the source of a valuable link, it seems that there is little value in using these services for link building. However, some of the sites do provide links and a few allow you to tailor the anchor text. (If you’re not familiar with ‘dofollow’ or ‘nofollow’ links, a good rule of thumb is that the ‘dofollow’ or ‘followed’ links are the kind that usually give some SEO benefit and ‘nofollow’ links generally don’t.) Most sites either didn’t give a link or gave a ‘nofollow’ link”.
To get a feel for which sites might be best for links, we could use how highly each press release page ranks in search results as a rough indicator of how much link juice that page might be able to pass. When one of our releases appeared on page one of Google web search (and the free release site provided a link) we rated that site highly for link building (note, this is a very simplistic approach, but good enough to get a feel for the sites; a more detailed analysis might give slightly different results).Summary
In short, I think the free websites hold relatively little value in marketing campaigns. I believe think time spent thinking how to be a thought leader, create something remarkable (campaign or product), really focussing on how to be news worthy is a much more valuable use of time than trying to sell a story to the press. However, that said, I appreciate things do need a helping hand and its not always as easy as – “just be remarkable”. With that in mind I think testing some of the premium services could well be worthwhile exercise and they should probably be built into any content marketing processes. The free sites I don’t think deserve any attention based on these findings?!
A recent blog post by Dan Bosomworth on the social radar highlights other opportunities for distributing content to valuable outposts, it is well worth reading in light of the above.
