• How to use public Wi-Fi networks safely? Bank plastic cards How can you determine whether a public Wi-Fi network is safe or not?


    Five tips for virtual travel without fear.

    Don't connect without knowing the risks.
    Whether it's a local bar, a city-owned network, or a hotspot from your mobile operator, public Wi-Fi networks continue to proliferate. Especially in business districts, where you will instantly find a high-speed network to connect to.
    However, network access is usually granted with the requirement of some personal information. Once connected, you find yourself sharing the network with many other people - and some of them may be willing to spy on your activities.
    Below are five tips for using public Wi-Fi safely while protecting your information.


    1. Consider the risks

    Don't stay online longer than you have to.
    Public Wi-Fi is inherently less secure than your home network because you're sharing the network with dozens, sometimes thousands of strangers, rather than a small group of people you trust. So if you want absolute, 100% privacy and security from public Wi-Fi, just don't use it. And if you absolutely need to make this contact, then keep in mind that you are taking on the risk that a complete stranger can spy on your Internet session.
    How will this knowledge help you? With this in mind, using common sense and caution, you will ensure that the session does not become dangerous. If possible, avoid making bank transactions or viewing business emails. Choose neutral activities—watching sports or news sites or something similar—where it doesn't matter whether your actions are being observed.
    In addition to being careful in your actions, try to follow these rules: stay online as little as possible, disconnect immediately after you're done, and make sure your laptop and phone's antivirus software remains up to date.

    2. Read the fine print

    Don't ignore security policy pop-ups.
    We all believe that we need to read the fine print, but we don't actually follow that advice. Doing this is especially important when connecting to a public Wi-Fi network. What exactly do you provide instead of wireless Internet? How is your email, phone number, or anything else going to be used?
    You are essentially putting your trust in the company or individual not to spy on you. Take a popular chain of coffee shops: the brand is unlikely to covertly monitor customer activity on the Internet, but rather collect insignificant information for marketing purposes. Therefore, weigh the options and make a choice.
    For completeness, you can read the Wi-Fi access rules set by the brand in advance. Before going out into the city, if you know your future route, you can identify establishments where it seems safer to connect.

    3. Opt for an HTTPS connection

    The green “HTTPS” beginning in the link text indicates increased connection security.
    When your browser navigates to a site whose URL begins with “https://,” a green padlock icon appears in the address bar. This means you're on a site that uses Hyper Text Transfer Protocol Secure, or HTTPS, jargon for using an encrypted connection to that site.
    In fact, HTTPS mechanisms encrypt all of your activity on a given site. This makes it difficult for someone sitting behind you in a cafe, or the owner of a hotel router, to track the data you share. If possible, only visit sites that use this protocol.
    As we said above, it is better to visit sites with general information when using public Wi-Fi, rather than browsing through social networks or email.
    However, if you need to visit a site with more sensitive information, pay attention to the green padlock and “HTTPS” to ensure security. Luckily, most popular sites that require authentication, from Google to Facebook (and Orbios among them), now use HTTPS.

    4. Install a VPN

    Choose a VPN, but choose wisely.
    Installing a VPN (Virtual Private Network) application is perhaps the most effective way to safely use public Wi-Fi, accessible to everyone. But even this does not provide a complete guarantee of safety. While providing the ability to spoof your location or watch foreign TV, a VPN also encrypts all data sent and received through your computer or phone. Like working with HTTPS, the program will make it much more difficult for other people on the same network to spy on what you're doing.
    You'll have to spend some time choosing a quality VPN because, essentially, you'll be entrusting all your Internet traffic to its developers. As a rule, reliable and fast work implies payment. If you intend to use a reliable and proven service, pay attention to this regularly updated rating of VPN applications. We wrote in more detail about VPN.

    5. Select a network

    Not all Wi-Fi networks are configured the same.
    The operating principles of different Wi-Fi networks are not the same. Since there are usually several networks to choose from to connect to, you should make the best choice. Any network that has a complicated connection to it, such as buying a coffee, asking the staff, or paying a small fee, will be significantly more secure than a completely open network that anyone can use.
    For security reasons, you should also choose a network created by a well-known company or brand, and avoid networks that appear out of nowhere. Finally, we recommend that you still connect to the same networks at the same establishments. The more access points you use, the more companies you give away your personal data to be torn to pieces.
    Orbios uses all technologies that increase the security of your session, but you should not neglect the described rules when working with any sites.

    Everyone knows from childhood that electrical appliances require special attention, but annoying troubles involving them arise with enviable regularity. Expert advice based on an analysis of the causes of fires and injuries due to the incorrect use of electrical appliances will warn you against such troubles.

    1. Under no circumstances should you use any electric heating devices that are made using a “handicraft” method for heating.

    2. The devices should not have any damage or malfunctions that could lead to fires, for example, damaged insulation, faulty thermostats, unstable stands.


    3. Do not leave electric heating devices plugged in unattended. This will not only save electricity. Note that the main role of a device such as a thermostat is to turn the heating device off and on. In general, the temperature controller allows you to solve a lot of different problems. It is especially convenient to use it in apartments where they use the “Warm Floor” system.


    4. Do not use any electric heating devices to dry clothes or linen.


    5. When using an iron, electric stove, electric kettle, electric fireplace, you need to install them at a distance of at least 0.5 meters from flammable objects.


    6. It is imperative to constantly monitor the serviceability of electrical wiring, the condition of insulation and the integrity of all electrical products in the house. If there is any doubt that you can install the wiring correctly or repair the damage, contact an electrician. Saving can be costly.

    How I safely visit ANY website and run virus-infected programs without infecting my PC. Do not use Internet Explorer.

    • How to safely use keygens (even if they contain Trojans)? - running them in a virtual machine or in Sandboxie (paid, but there is a trial)!
    • How to use different software without installing it on your computer? How to check your PC with another (two, three) antivirus?
    • How to safely download using torrent programs? How to safely download from a hacker site (just visiting which should have infected your PC) and get away with it, then you are welcome to read this article to the end.

    Having become acquainted with the Virtualbox program, you will agree that it has a lot of useful aspects, so I now call it Pandora's chest (for greedy software manufacturers).

    How to use keygens safely.

    I’ll make a reservation right away. Some keygens hack the program during operation - these require “physical contact” and we launch them in a virtual machine only to hack the software that you install in this very virtual machine. Others select a code based on date and other data and give it to us. These can be run in a virtual machine, and the software can be installed on your PC. Why all this? The fact is that some cracks install a Trojan at the same time as hacking the software. It is impossible to determine which of them will do this “by face”, therefore, for the safe use of keygens, it is good to isolate them all in a virtual machine. And I heard that sometimes antiviruses say “TROJAN” to a keygen that does NOT install a Trojan! That’s why it’s not always easy to figure out which crack has a Trojan and which doesn’t.

    How to use a bunch of software without installing it on your PC?

    By putting it in a virtual machine! In summary, we have that some of the cracks are installed by Trojans. So let these Trojans live in a virtual machine... Of course, putting games there is not always good. For example, Starcraft 2 and similar monsters cannot be played in a virtual machine. Although in Diablo 2 it is possible. All sorts of photoshops can be placed there. You can then send the pictures to yourself by mail. It is better not to share shared folders with such an infected machine. But it’s easier to install a trial Photoshop, directly from the offsite, using the eternal trial technology. Which has some differences for Photoshop. Here's Photoshop for free! How to scan your computer from Virtualbox with another antivirus.< И наконец, как защититься от интернет вирусов и хакерских сайтов? Как безопасно качать по торрент протоколу?

    You already understand that by installing OS Ubuntu in a virtual machine, we can organize a secure Internet. Most dangerous sites work something like this. When your browser accesses the site, it downloads files to your hard drive. To the folder Temp. And if there is a virus among them, then you will be infected. Or Windows vulnerabilities that have not yet been fixed by updates are used. Or something else. I offer two options on how to use the Internet safely.

    • Visit not the sites themselves, but a copy of them saved in the Yandex and Google cache. There are no Internet threats or Internet viruses. Pay attention to WOT's reputation. ATTENTION! Scammers are already doing this trick - having created 50 fake accounts in WOT, they make the icon color green through fake votes. But if you go to the reviews about the site, you will see statements from real people (and not really - they betray themselves with too loud praises for the site). This will help you get an idea of ​​the site.

    • Visit sites through proxy servers. For example, http://www.4proxy.de/, http://biglu.ru/ - malicious scripts are not designed to “pierce” the PC of the proxy server sitting behind the “mighty back”. A large collection of such “convenient” proxies opens on the 2ip.ru website in the Anonymizer section.

    • If the above options do not apply, visit sites whose content may contain Internet threats using a virtual machine. The same method is needed for safe torrent downloading.

    A method for safely visiting web pages and downloading files using the torrent protocol.

    When downloading a torrent, the program receives a list of participants. Those. the IP and operating system versions of those exchanging files are known. To all participants - and hackers too. Then it's a matter of technology. Using the IP address, which is clearly visible in the torrent downloader window, we scan the ports and attack the user’s PC. Result - the file is downloaded and the Trojan is installed as a gift.

    If we go to such a site from a virtual machine running a different operating system, then hacking either will not happen (most often such sites are designed for Windows users), or Ubuntu will be hacked. Which is not very critical. Why? Because the procedure for using such a virtual machine for safe Internet surfing looks like this.

    1. Install Virualbox on your PC.
    2. Turn off the virtual machine running Ubuntu OS and copy the virtual hard disk from drive C to drive D.
    3. We download torrents inside the virtual machine, and then upload them from the virtual machine to ex.ua or Yandex disk. Then we turn off the virtual machine and calmly download the files using the more secure http protocol.
    4. After an intensive search for something like this on the Internet, having copied all the necessary data from the virtual machine to our hard drive, we replace the virtual disk with Ubuntu installed with a clean copy from drive D.

    And our dearest Windows will remain intact.

    On June 25, a large fire in one of the two-story houses was extinguished on Kharkovskaya Street in the city of Ulan-Ude. Presumably, a gas cylinder exploded, which contributed to the rapid spread of the flame.

    What can cause gas to explode in a house?

    This can happen if gas has entered the premises due to a faulty gas pipeline or the carelessness of residents. For this, a small source of fire is enough - from a match or from sparks from a light switch.

    Users of gas samples should know and strictly follow the following rules for their use and care:

    • The gas cylinder must stand level on a hard surface, at an angle of 90 degrees. The cylinder must be at least 1.5 meters away from the stove, stove or radiator;
    • Do not change the gas cylinder if there is a fire nearby or electrical appliances are turned on. Each time with such a replacement, it is also necessary to change the gasket between the cylinder tap and the regulator;
    • Remember that you cannot store more than two cylinders in one room. It is also prohibited to store them in a room where the temperature rises above 40-45° and in direct sunlight;
    • Keep children away from gas appliances;
    • Use only serviceable and properly functioning gas appliances; in no case should you use homemade gas appliances, incompletely equipped ones, or home-made appliances;
    • Follow the sequence of turning on gas appliances: first light a match, and then open the gas supply;
    • If the gas supply stops, immediately close the shut-off valve at the burner and the spare valve on the gas pipeline;
    • Do not use gas stoves to heat your apartment;
    • To avoid gas leakage, make sure that when cooking, boiling liquids do not spill over the fire;
    • Clean burners regularly;
    • Do not tie ropes to gas pipes, stoves, taps, or hang laundry or other things on them;
    • Do not store cylinders with flammable gases in individual residential buildings, apartments and living rooms, as well as in kitchens, on escape routes, in basements, basements and attics, on balconies and loggias;
    • Refill gas cylinders only at specialized points;
    • Do not connect or disconnect gas stoves in apartments yourself;
    • When leaving home, do not forget to turn off the gas stove and close the valve on the cylinder.

    This is especially important for summer residents who leave their homes for a long time.

    How to check for gas leaks?

    There is a simple method for detecting leaks - this is an ordinary soap solution. You will also need a brush - you can use a shaving brush or a thick paint brush. Wet the brush in the soapy solution and coat the gas pipeline. If there is a gas leak, you will notice small soap bubbles where the gas escapes.

    Never check a leak using lighters and matches - this is very dangerous! Better yet, call a gas technician.

    It smells like gas. What to do?

    1. Stop using the gas appliance: turn off the gas on the stove, close the gas pipe.
    2. Eliminate the appearance of ignition sources: open flames and sparks (matches, cigarettes, lighters, electrical switches, electrical appliances, electric bells, telephones).
    3. Immediately remove all family members from the premises, warn neighbors about the incident and urgently ventilate all premises, including basements.
    4. Call the emergency gas service by phone “04” or firefighters and rescuers by phone “01”, from a mobile phone “101”, “010”.
    5. Leave the gas-contaminated room until emergency services arrive and the accident is eliminated.

    A domestic gas explosion in a room can cause the collapse of a building or part of it, causing a fire, injury and death.

    The ease with which people can steal your personal information is the cost of banking, shopping and communicating online. To use the Internet safely, use the following strategies.

    Method 1: Protect your personal information

    1. Don't use simple passwords. Using the word “password” or the set of numbers “1234” as a password is like putting a house key in front of the entrance. Fraudsters can easily guess and crack the password. Instead, create a long password that contains both letters and numbers (signs). It is advisable that the password relates to something important to you. For example, if you had a pet goldfish as a child and his name was Mr. Bubble, you might come up with a very good and complex password, such as “mr1pozyr736,” that only you can understand. Write down all your passwords.

    2. When subscribing to the mailing list, downloading files, signing agreements, always read the fine print. If you do not want to receive junk mail or be put on telephone agent lists, please note the small box at the bottom of the page that asks if you want to receive information and offers from other companies.

    The best sites themselves state that they will not sell your data to other companies (although they themselves may send you a lot of junk mail). Some sites require you to provide all your information in order to receive their product. Fill in only required fields marked *. If the information field does not have an asterisk, then filling it out is optional and you can leave it blank.

    3. Do not give your full name, address or telephone number to anyone online unless you trust and know the person personally. This is especially important in chat rooms or when negotiating for work or on sites designed to meet or find people with common interests. Beware of letters that give very vague answers and there is no clear answer to any of the questions you asked, as well as letters that talk about non-cash payment or the conclusion of any business agreement while the representative is “abroad”, or o receiving gifts or inheritance from an unknown source.


    4. Be careful and don’t fall for online scams. Beware of fraudulent emails claiming to be from eBay, PayPal, a bank or a company you trust. These emails request personal or confidential information. This is called phishing. This email may notify you that there is a problem with your account or password. The email may contain a link that you need to click.

    Forward any of these letters to the name of the company on behalf of which it claims to have been sent. They will confirm whether the email message you received was real or not. Also, keep in mind that some email services such as Yahoo!, MSN, Hotmail. Gmai, Mail.ru never specify your email password. Don't fall for scammers.

    Method 2: Protect your data and connections


    1. Make sure that you use (and regularly update) anti-virus, anti-Shionware programs and an access restriction system (firewall). You can use, at your discretion, either an access restriction system (firewall) purchased with your operating system or a program purchased from other suppliers. Do not use the two systems together as they may interfere with each other.


    2. When you use a public wireless connection, turn off file sharing and network discovery features. Both of these features put your files, messaging, and system at risk of being opened by anyone over the air, not just hackers. On Windows, these features can be disabled via Control Panel > Network and Internet > Network and Sharing Center. On Macintosh, features can be disabled through System Preferences > Sharing.

    If there are many wireless sources around you but you do not need to use the Internet, turn off all your wireless devices. On some devices this is just an on/off switch, on some devices you will need to configure this yourself, for example on a Macintosh you need to click on the Wi-Fi icon and turn off AirPort.


    3. Always verify information about secure transactions. The best companies have many safety features. You can see a gold padlock at the bottom of the page which indicates the site is secure. When you provide any bank details or other information, please ensure that the connection is secure (the URL should start with "https://" instead of "http://") and that the site is trustworthy. Not every site that runs HTTPS or accepts payments is trustworthy, even if it has the required secure connection.


    4. Set your browser to block inappropriate information, especially if you have children.

    1. Download files or software from sites that have been rated or verified by reliable sources. Use download resources that have high ratings and verified prices, and that carefully review the files they provide for download (for example, download.cnet.com). If you doubt the security of a site, then either simply search the name of the site in search engines, or search along with the word “scam” to see if the search engine returns any results. Do not illegally download copyrighted products without paying for them.


    2. Never open attachments in email received from unknown recipients, unless you trust them and you have security settings on your computer. Some unwanted emails may contain viruses or spyware that can harm your computer. Such emails may be automatically marked as "spam" or "junk", but virus-infected emails from unsuspecting friends can also slip into your inbox.

    • If you use email programs such as Outlook or Thunderbird, then disable the attachment preview feature. Since with this function you cannot decide for yourself whether to open the attached file or not. Look in the settings of your email program and disable options such as “Show Attachment Previews”, “Display Attachments Inline"s” and so on.

    Adviсe

    • It is best to have three email accounts. One for friends and websites, another only for work issues, the third for personal clients, banking correspondence, job searches and other things that require increased protection. Use a suitable name and a strong password for your last two email addresses. Some companies may keep your work email address after you leave, so make sure you have a backup copy of all the documents you need.

    Warnings

    • Keep a backup of important emails and documents on a flash drive, in hard copy, or both.
    • Use good test questions that only you know the answers to.
    • Abandon your email or any accounts that have been hacked after you have copied any data that can be saved. Immediately notify your bank or workplace about such changes. You may have to change all passwords or account numbers and similar information immediately (if it was ever mentioned in your email). Complain about the problem directly to the representative of the organization providing your email services.
    • If your computer is hacked via the Internet, then all your information may be at risk. Update your virus protection and remove the virus. If important documents or information have been stolen, notify your bank and place of business. Report the crime to law enforcement.
