Soluții pentru problemele tale IT
If you regret not making a backup of your phone, you should enable the option right now to avoid further data losses in the future. Setting up an automatic Google Drive backup is not difficult and only takes a few taps.
[mai mult...]You probably shouldn’t be too paranoid about these attacks. We haven’t seen widespread reports of charging ports causing problems. However, many possible attacks could happen over a USB port, and avoiding the risk is easy enough that it won’t inconvenience you.
The main problem is that USB doesn’t just transmit power—it sends data. That’s why you can plug your phone into your computer to transfer files back and forth, update the phone’s operating system, and back up its contents.
A correctly behaving USB charging port wouldn’t even try to access your phone’s data. But there’s nothing stopping it from trying after you plug in a USB cable. A charging port could try to access private data on your phone or exploit a security vulnerability and run dangerous code on your device. This type of attack is known as “juice jacking.”
While older phones just made your photos and other data accessible whenever you plugged in a cable, current iPhones and Android phones usually require your permission to share things. Your iPhone will prompt you to “Trust This Computer” when a device you’re plugged into wants access. On Android, you must enable transferring files over the connection. Even if you have USB debugging enabled, you must permit the device to access it.
If you don’t give your phone those permissions, it will still allow charging over the port but not allow data transfer.
With an iPhone, you’re probably safe unless the charger attacks your phone through an unknown security hole. Of course, Apple just added “USB Restricted Mode” to the iPhone and iPad to prevent them from being attacked by password-cracking tools connected to the Lightning data port.
If you have an Android phone, there are bigger risks. Most Android phones run outdated operating systems, which could easily have unpatched security holes that could be attacked through a USB port. They could be attacked in other ways, too. Many current Android devices from eight different manufacturers including Samsung, LG, and HTC are vulnerable to AT commands be sent over a USB cable. As usual, you’re safest if you have a Google Pixel device that’s up-to-date, but even that could theoretically be attacked.
[mai mult...]The internet is home to roughly 1.7 billion websites. Unfortunately, many of these websites live only to scam you out of your personal data or money. Here are a few signs to look out for to spot a fraudulent website.
The first thing you should do before visiting a site is ensure that the domain name is the one you intend to visit. Fraudsters create fake sites masquerading as an official entity, usually in the form of an organization you would likely recognize, such as Amazon, PayPal, or Wal-Mart. Sometimes the difference between the real site’s name and the fraudulent site’s name is almost unnoticeable. For example, the cybercriminal may build a site using rnicrosoft.com (note the “r” and “n” at the beginning of that address, which looks similar to an “m”), but you think you’re visiting microsoft.com.
There are two basic ways the cybercriminal, or “threat actor,” gets you to visit the fraudulent site. The first way is by a method known as “phishing.” Phishing is a form of cyberattack that is delivered mainly by email. The threat actor tries to entice you to click a link in the email that will then redirect you to a fraudulent copy of the real website.
Another way the threat actor may get you to visit the fraudulent site is by a method known as “typosquatting.” Typosquatting uses common misspellings of domain names (for example, amazom.com) to trick users into visiting fraudulent websites. You think you entered the domain name correctly, but you’re actually visiting a fraudulent copy of the genuine site. If you’re lucky, your web browser will warn you.
Regardless of how you get to the site, once you log in to this fraudulent website, the threat actor will harvest your login credentials and other personal data, such as your credit card information, and then use those credentials themselves on the actual website or any other website where you’re using the same login credentials.
The first and most basic method of spotting a fraudulent website is to make sure the domain name is the one you truly intend to visit.
When you visit a website, look for the padlock to the left of the URL in the address bar. This padlock indicates that the site is secured with a TLS/SSL certificate, which encrypts data sent between the user and the website.
If the website hasn’t been issued a TLS/SSL certificate, an exclamation mark ( ! ) will appear to the left of the domain name in the address bar. If a site isn’t TLS/SSL certified, any data you send is at risk of being intercepted. The downside to this is that not all SSL certificates are authentic. These sites are usually caught pretty quickly, but it’s still best to look a little harder at the padlock just to be sure. Unfortunately, you can only dig deeper if you’re browsing the web using a desktop.
While this won’t always protect you from fraudsters, the padlock (and the certificate information) is a good indicator that you’re visiting a legitimate site.
Fraudulent websites generally don’t go to the extent that genuine websites go to concerning privacy and return policies, if at all. For example, Amazon has a pretty thorough return policy and privacy policy that details everything the customer needs to know about each respective policy.
If a site has a poorly written return or privacy policy, that should raise some red flags. If a site doesn’t have these policies stated on their website at all, avoid them at all costs, as the site is likely a scam site.
A spelling or grammar mistake is likely to happen now and again, even on the most authoritative of websites. However, most websites have teams of professionals creating these websites. If a website looks like it was created in a day by one person, is riddled with spelling and grammar errors, and has a questionable user interface (UI), there’s a chance that you’re visiting a dangerous website.
If you’d like to add another layer of protection between you and fraudulent websites (and also give you a heads up if you may be visiting one), then use a site scanner such as McAfee SiteAdvisor.
These tools crawl the web and test sites for spam and malware. If you visit a dangerous (or potentially dangerous) site that the program determines may contain dangerous content that could harm your PC, you’ll be notified and asked to confirm you still want to proceed to the site when you try to visit.
While site scanners are helpful in spotting a potentially fraudulent website, not all fraudulent websites will be flagged. While you use them as an extra layer of protection, still be conscious of the sites you visit.
If you’re a victim of an online scam, there are a few measures you can take to protect yourself (and potentially protect others). What you need to do next depends on what type of information you believe the scammer may have on you.
If you purchased something using your credit or debit card from the fraudulent site, the first thing you should do is call your bank immediately and report to them what happened. They’ll freeze your accounts and cards so that the threat actor can no longer purchase anything with your details. If you believe the threat actor may also have your personal information, such as your Social Security Number, date of birth, address, and so on, you’ll want to freeze your credit so that the fraudster can’t take out any loans or open any accounts in your name.
Once that’s taken care of, file a report with your local police, notify the Internet Crime Complaint Center (IC3), and report the site to Google.

It’s a pretty cool trick to know. iOs 15 introduced a feature in the Photos app called “Visual Lookup.” After you take a photo, the app can identify various objects.
