If you're a WhatsApp user, you'll have to share your personal data with Facebook's empire from next month – or stop using the chat app

 If you don't agree then, well, you'll just have to use the infinitely better Signal...


WhatsApp users must agree to share their personal information with Facebook and its wider empire if they want to continue using the messaging service from next month, according to its terms and conditions.

“As part of the Facebook Companies, WhatsApp receives information from, and shares information with, the other Facebook Companies,” its privacy policy, updated this week, states.

“We may use the information we receive from them, and they may use the information we share with them, to help operate, provide, improve, understand, customize, support, and market our Services and their offerings, including the Facebook Company Products.”

Said information includes your personal data. Thus, WhatsApp users who want to keep using the software must agree to allow their personal info to be shared with not only Facebook but also its subsidiaries as and when decided by the tech giant.

Users will be presented with the following choice in the app: accept this arrangement by February 8, or be blocked from using the end-to-end encrypted chat app.

Windows 10 update kills Adobe Flash

We have issued an article related to Flash RIP back in May 2020


Microsoft has rolled out an optional update for Windows 10 that permanently removes Adobe Flash from the operating system and prevents it from being re-installed.

Ahead of the long-awaited end-of-life date for Adobe Flash, which will fall on 31 December 2020, Microsoft has released a tool for Windows 10 and Window Server that strips out all elements of the software.

The company has released the removal tool in advance of this cut-off point to help customers test and validate their environments for any impact that might occur by the removal of Adobe Flash Player.

Adobe decided in 2017 to retire its Flash Player due to the diminished usage of the technology, and the availability of better and more secure options including HTML5, WebAssembly and WebGL.

Flash Player updates and patches will continue to be rolled out between now and the end of 2020, although will cease once 31 December is reached. Disruption shouldn’t be too severe, however, given just 5% of websites were still using the environment as of 2018.

Ransomware Attacks are not problem for us

 


If there is one characteristic that defines cybercrime today, it is the capacity to evolve and adapt to new environments and the ability to find ways of evading the cybersecurity measures taken by victims. 

Ransomware is no exception. One of the main features of ransomware as a threat, in addition to kidnapping data, is that it is constantly reinventing itself to persist over time and ineffectiveness.

This type of malicious software has evolved greatly since it began, and today there is a wide variety of families in existence, giving rise to new, more sophisticated strains.

Did you know that?

  • 65% of ransomware infections are delivered via phishing 
  • A ransomware attack will take place every 11 seconds by 2021 
  • 85% of ransomware attacks target Windows systems. 
  • The average cost of a ransomware attack in 2019 was $133,000 
  • 50% of IT professionals don’t believe that their organization is ready to defend against a ransomware attack.  
  • Hackers attack  every 39 seconds or an average of 2,244 times a day 
  • Between January 1st and June 30th, 2020, ID Ransomware received 100,001 submissions relating to attacks that targeted companies and public sector organizations. 
  • 90 % of IT pros had clients that suffered ransomware attacks in the past year 
  • Ransomware costs will reach $20 billion by 2021 
  • 51% of businesses have been impacted by ransomware in the last year

What is Grep Command in Linux? Why is it Used and How Does it Work?

 Grep is a command-line utility in Unix and Linux systems. It is used for finding search patterns in the content of a given file.

With its unusual name, you may have guessed that grep is an acronym. This is at least partially true, but it depends on who you ask.

According to reputable sources, the name is actually derived from a command in a UNIX text editor called ed. In which, the input g/re/p performed a global (g) search for a regular expression (re), and subsequently printed (p) any matching lines.

The grep command does what the g/re/p commands did in the editor. It performs a global research for a regular expression and prints it. It is much faster at searching for large files.

grep command meaning

This is the official narrative, but you may also see it described as Global Regular Expression (Processor | Parser | Printer). Truthfully, it does all of that.

The interesting story behind the creation of grep

Ken Thompson has made some incredible contributions to computer science. He helped create Unix, popularized its modular approach, and wrote many of its programs including grep.

Thompson built grep to assist one of his colleagues at Bell Labs. This scientist's goal was to examine linguistic patterns to identify the authors (including Alexander Hamilton) of the Federalist Papers. This extensive body of work was a collection of 85 anonymous articles and essays drafted in defense of the United States Constitution. But since these articles were anonymous, the scientist was trying to identify the authors based on linguistic pattern.

The original Unix text editor, ed, (also created by Thompson) wasn't capable of searching such a large body of text given the hardware limitations of the time. So, Thompson transformed the search feature into a standalone utility, independent of the ed editor.

If you think about it, that means Alexander Hamilton technically helped create grep. Feel free to share this fun fact with your friends at your Hamilton watch party. 🤓

What is a Regular Expression, again?

A regular expression (or regex) can be thought of as kind of like a search query. Regular expressions are used to identify, match, or otherwise manage text.

Regex is capable of much more than keyword searches, though. It can be used to find any kind of pattern imaginable. Patterns can be found easier by using meta-characters. These special characters that make this search tool much more powerful.

Regular Expression aka regex

It should be noted that grep is just one tool that uses regex. There are similar capabilities across the range of tools, but meta characters and syntax can vary. This means it's important to know the rules for your particular regex processor.

Adobe FLASH RIP


Adobe posted on the 25th of July 2017 the forthcoming death of Flash player.


Adobe has long played a leadership role in advancing interactivity and creative content – from video, to games and more – on the web. Where we’ve seen a need to push content and interactivity forward, we’ve innovated to meet those needs. Where a format didn’t exist, we invented one – such as with Flash and Shockwave. And over time, as the web evolved, these new formats were adopted by the community, in some cases formed the basis for open standards, and became an essential part of the web.

But as open standards like HTML5, WebGL and WebAssembly have matured over the past several years, most now provide many of the capabilities and functionalities that plugins pioneered and have become a viable alternative for content on the web. Over time, we’ve seen helper apps evolve to become plugins, and more recently, have seen many of these plugin capabilities get incorporated into open web standards. Today, most browser vendors are integrating capabilities once provided by plugins directly into browsers and deprecating plugins.

Given this progress, and the collaboration of several technology giants – including Apple, Facebook, Google, Microsoft and Mozilla – Adobe has planned to 'switch off' Flash. Specifically, they will stop updating and distributing the Flash Player at the end of 2020. They encourage content creators to migrate any existing Flash content to these new open formats.

Firefox and Chrome keep notifying users when visiting flash enabled sites that they will stop working at the very same date. Thus get prepared, any site you depend on, is using Flash, you will not be able to open or run (if you are the owner/hoster) by the end of this year.

Critical Flaw in Windows Preview Pane

Microsoft on 23/3/2020 issued Security Advisory ADV200006 for a "Critical"-rated remote code execution vulnerability in both supported and unsupported Windows systems.

Microsoft updated its security advisory on March 24 to indicate that the vulnerability is just rated "Important" for Windows 10, Windows Server 2016 and Windows Server 2019 systems. It's still rated "Critical" for older systems, though. "We do not recommend that IT administrators running Windows 10 implement the workarounds described below," the advisory explained.

The vulnerability, associated with the Adobe Type Manager Library in Windows systems, has been exposed to "limited, targeted attacks," per the advisory. The library "improperly handles a specially crafted multi-master font." This flaw can be exploited by "convincing a user to open a specially crafted document or viewing it in the Windows [Explorer] Preview pane."

There's no patch currently available. Microsoft's advisory offered three "workarounds" to implement, but they all have limitations.
