Or soups?  TikTok claims it wasn't attacked after all

TikTok refutes recent cyberattack news. Recall that a group of hackers published an image allegedly taken from the application’s database.

according to edgethe hackers in question say they gained access to the TikTok server, which held two billion records and the equivalent of 790GB of users’ personal data, as well as the platform’s statistics and code.

The AgainstTheWest group claimed responsibility for the attack, and while the name might seem like a hacker group targeting Western countries, the attackers claim to only target countries and companies hostile to Western interests.

TikTok says it “found no evidence of a cyberattack” and that the data the hackers are referring to was already publicly available. “We confirm that the data samples in question are public and do not involve compromising TikTok systems, networks or databases. We believe that users do not need to worry or do anything, and we remain committed to the safety of our global community.”

There is an idea in the images that the hackers posted that WeChat was also under attack at the same time. The application has not yet made any public statements about this.

Although WeChat and TikTok are owned by Chinese companies, they are not owned by the same company; the former is owned by Tencent and the latter by ByteDance. So finding two in the same database indicates that this was not a direct hack on every platform.

Troy Hunt, creator of the HaveIBeenPwned data breach notification service, confirmed on his official Twitter account that some of the data shown is correct. Nonetheless, Hunt also found no information that is not publicly available on TikTok..

Gmail: How to Detect a Viral Attachment and Avoid It

When it comes to email, there are several ways an attack can reach a victim. Dangerous links, persuasive language, and infected attachments are all elements used to scam people. In the same way, confidential data and money are stolen. So how do you avoid becoming a victim? In this article, we will explain how to detect and avoid virus attachment in Gmail, which actually applies to any email client.

Gmail: How to Detect a Viral Attachment and Avoid It

Receive attachments daily very often. The documents, audio files and images are often attached to these emails. But not all attachments we receive are necessarily good.

Malicious attachments are those that are used to spread malware onto someone’s device. Cyber ​​attacks need vectors to spread these dangerous programs. This can be done in several ways. Dangerous investments – the most popular way.

However, when a victim downloads a malicious attachment, they are actually downloading malware onto the device. Depending on the type of malware, it can affect the machine in different ways. Some less bad, some worse. However, the consequences of downloading a malicious attachment are severe in most cases.

Signs of a Dangerous Attachment

For everything he can do, it is important to identify threats.

First, it is important to analyze the type of files

When we receive any attachment via email, we can see the extension or suffix of the file. There are many different file types, most of which are .jpg, .zip, or .pdf. While there are no definitively malicious file types, there are some that are most commonly used to spread malware.

The main types of suspicious file attachments are .exe, .vbs, .scr, .cmd, and .js. It is these types of files that can be used to spread malware.

Pay attention to the content of the email

The content of the email may also indicate whether a particular attachment is malicious. For example, if you receive an email where the sender claims to have attached a document but an MP3 attachment, then you are most likely dealing with a false attachment. This is to put it mildly.

check sender

The key step is to verify the sender’s email address. An attacker cannot replicate and use a trusted source address, but will try to create very similar addresses.

For example, an attacker might slightly change the name of the company in the address (for example, “w0rten” instead of “worten”). When receiving any type of email from a new sender, be sure to take a close look at the address.

Will smartphones do away with cameras?

Published

on

How many people do you see on the street with a special camera in their hands? Probably very few, especially since smartphones have begun to offer shooting quality at least comparable to a DSLR.

However, in terms of quality, despite the great strides made by Apple, Samsung, Xiaomi, Huawei, Vivo, Oppo, etc., the truth is that a good camera still outperforms any high-end smartphone. At least for a while!

Do smartphones have what it takes to complete the cameras?

Thus, Sony is no longer the only giant in the mobile technology world who believes that smartphones have what it takes to surpass the image quality of digital SLR cameras in the near future. After all, Judd Heap, VP of Camera Product Management at Qualcomm, seems to share a very similar sentiment. You know why?

Because the capabilities of sensors continue to grow, and in fact the level of development and innovation in this area is much higher than in the rest of the photographic industry.

What’s the secret?

S22 Ultra, Vivo, X80 Pro

Apparently, the potential lies in the level of processing that exists in the world of smartphones, especially in the higher ranges. After all, compared to the most powerful cameras on the shelves, be it Sony, Canon or Nikon, any high-end smartphone is at least 10 times more powerful in terms of processing power.

Computing power, which, as you understand, has only increased.

Big brands don’t want to fight smartphones.

As you may know, Canon has already announced the end of its DSLR lineup, and it looks like Nikon is joining the same train with its focus on mirrorless cameras.

In short, the greats of this world know that it is impossible to fight the practicality that smartphones offer.

So what about the megapixel war? This is an obstacle to evolution!

A Qualcomm expert believes that this new numbers war in the world of smartphones is useless, and that for a good development of the market, it would be a good idea to bet on sensors between 40 and 50MP.

A curious proposition, as Samsung will make a big and ugly 200MP bet from next year on its top of the range Galaxy S23 Ultra. Here we must take into account that more megapixels does not necessarily mean larger sensors. Pixels will be smaller, and for this reason, they may have difficulty getting light through. In the near future, it is very likely that the maximum sensor size for smartphones will not exceed one inch (1 inch).

Besides, what do you think of all this? Do you think that cameras will die, remaining only for professionals? Share your opinion with us in the comment box below.
