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.

A black hole has swallowed a star and is spewing a jet at us

A black hole has swallowed a star and is spewing a jet at us

One Black hole it swallowed a star and fired relativistic jets at some corner of the universe far from our galaxy — enough to be the most distant black hole food astronomers have ever observed. The discovery became possible only because the jets were directed in our direction.

When a star gets too close to a black hole, a powerful gravitational force begins to tear it apart. stretching your matter like spaghetti🇧🇷 This is a one-way process. Although it has not yet passed through the event horizon (a point from which not even light can escape), the star is broken.

This event, dubbed AT2022cmc, was discovered in February this year by ZTF, an autonomous system that tracks and extracts information about unusual phenomena in the universe in visible light. Therefore, scientists sent several telescopes around the world to observe the source of radiation at other wavelengths.

Many wavelengths have been detected in the radiation released from this event, from gamma rays to radio waves, in addition to visible light itself. This was possible because the plane was directed in our direction (although without any threat), which is very rare.

The advantage of having the jet pointing towards the Earth is that in this way its brightness becomes much more intense, which allows it to be observed at different wavelengths and better calculate the distance to it. This led the team to calculate that the black hole was feeding when the universe was only a third of its current age, about 4 billion years old.

To get this result, the team needed to collect data from 21 different telescopes and compare the information to theoretical models of several types of known extreme events, such as stellar collapses and kilonova explosions.

The only scenario that explained the findings was a phenomenon called “tidal disruption,” where a black hole devours a star, stretching it like chewing gum. Other events from tidal disturbances have been observed beforebut this happened much closer to us and without jets directed in our direction.

Astronomers are constantly looking for these extreme events to better understand how these jets form, how they get so much energy, and why so little tidal disruption forms them. This is the first time an event of this type has been detected using visible light, so astronomers should invest even more in instruments like the ZTF.

This study was published in the journal Nature.

Google extends to all models

This list of updates from Google also has a few gems like Chromecast Audio that aim to bring the concept to the audio part. The Chromecast Ultra also now sees its updated version and gets the same bug fixes and other improvements.

To check your device version, Google recommends that you open the Google Home Google Home app, press and hold the device tile. Then click "Settings" and then "Device Information". In the "Technical Information" section, find the Cast firmware: "X.XXX.XXXXX".

How to access new software

Updating devices is extremely simple. It usually downloads updates automatically. To manually download the latest update, follow these steps:

  • Accessing the Chromecast Home Screen with Google TV
  • Select Settings, then System, then About, then System Update.
