I wrote on Medium in November 2019. I still remember the first story was written at the Suvarnabhumi Airport (BKK) in Thailand. I typed on my Pixel 2XL, using the on-screen keyboard when I was waiting for my girlfriend's arrival.

Not many people use Medium in Hong Kong, but I like reading on medium. Since the last US election, I gave up Facebook. Unlike Facebook, I post on Medium to share what I learned and enjoyed. Before I realized it, my English improved! (I know it still sucks).

When preparing my presentation, the flow and the arrangement of contents secretly…

I Passed!

I just passed the exam of ISSAP® — Information Systems Security Architecture Professional from (ISC)2®. It was one of the most challenging exams I took in my life. All the answers to the multiple choices are correct, but it is required to choose the best answer in most cases. I checked the member count from the official website. There are 25 active holders in Hong Kong and 2061 worldwide.

Here is my addition to extend the topic:

Most of us will not click on the email claiming we are a lottery winner nowadays. However, phishing attacks evolved and remained the most dangerous cyberattack for individuals or enterprises since the first phishing attack in 1995.

According to a report by email security company Valimail, over three billion spoofing messages are sent each day, nearly 1% of all email traffic. And this is costing quite costly damage to our society. …

“As bad as we are at remembering names and phone numbers and word-for-word instructions from our colleagues, we have really exceptional visual and spatial memories.”

Assuming you read my previous article and learned how to limit your exposure online. You set up a password manager and enabled multi-factor authentication for your accounts. There is more to be done to keep you safe. You might think your ID number or bank account numbers are the most sensitive digits. Sadly, with only your cell phone number, hackers can do far more damage with little effort.

Privacy | Technology

Unlike what we did in the past, we need a computer to be the digital self, most people spend most of the time online with their mobile nowadays. A few years ago, if you want to protect privacy with apps, you do not have much choice. But now, multiple options are available and so of them are also open-source and free of charge.

This time, I would focus on 5 areas for people to start with:

• Authenticator Apps
• Privacy-Focused Browser
• Password Manager
• Encrypted Messager
• Device Location Tracker

At the beginner level, let’s try them yourself and share them with people…

Facebook’s Ireland data supervisor (Helen Dixon) in the EU has opened an investigation into whether Facebook violated data protection rules regarding the leak of data reported earlier this month.

Again, the tech giant did not provide a statement afterward. Even if they did, I am sure there would be nothing pleased. On Monday, the EU Commission intervened. They pressured Ireland’s data protection commissioner on this case, according to the tweet of Justice commissioner of the EU, Didier Reynders:

There would not be a solution soon. Next would possibly be the repeating and useless PR stunt from Facebook and, if…

Facebook, Linkedin, Clubhouse

Since the invite-only and audio-only social media app launch in March 2020, Clubhouse became popular and attracted millions of users. Users enjoy the audio community with various topics in “rooms.”

I talked about the privacy and security risk of the app in February. If you still remember, Elon Musk helped Clubhouse leap during the frenzy of Gamestop, Wallstreetsbets, and Dogecoin. While the risks are still valid and not fixed, the personal data of 1.3 million Clubhouse users has been posted online on a popular hacker forum, according to a Saturday report from Cyber News.

The scraped data of Clubhouse users…

“Privacy is not something that I’m merely entitled to, it’s an absolute prerequisite.”
― Marlon Brando

One thing that steals my focus of this “Facebook Leak” is that no one contacted you about the hack or telling you what to do, unlike other companies. Therefore, instead of apologizing for failing to keep our data safe, Facebook’s product management director Mike Clark began his blog post by:

“It is important to understand that malicious actors obtained this data not through hacking our systems but by scraping it from our platform prior to September 2019,”

A few days later, after I shared…
