Update EVERYTHING

Settings -> Firmware
Update Firmware

Go to the terminal and use commands -

sudo apt update

sudo apt upgrade

You can also update ur stuff from Pop!_shop Image
Enable the firewall (search for gufw) ImageImage
Check for open ports -

Identifying open connections to the internet is a critical mission. Use the following command to spot any hidden open ports:

netstat -antp Image
Setup your VPN

Recommended: @ProtonVPN, @mullvadnet, @ivpnnet, @MozillaVpn

Make sure to download their Linux client. In my case - it's Proton VPN.

Download your secure messengers from Pop!_shop

My tools: @signalapp, @session_app, @element_hq

A good resource for comparison:
securemessagingapps.com
Change the default apps as per your preference -

My toolbox default:

Browser: @brave
Email Client: @mozthunderbird
Music, Video: VLC Media Player Image
Password manager - Get it from Pop!_shop.
I use the @Bitwarden premium plan to store all my passwords. This helps me generate different passwords for different accounts. It also helps me to use it as a TOPT authenticator.

Make sure you regularly update OS Recovery and change the settings of System and Application Settings as shown in the pic. Image
Secure your laptop using @Yubico

Privacy in #Monero (with FCMP) vs. #Zcash Shielded

When focusing solely on cryptographic theory, two major privacy engineering marvels emerge: Zcash $ZEC, using advanced zero-knowledge proofs & Monero $XMR, moving towards Full-Chain Membership Proofs (FCMPs).

🧵

Disclaimer: I’m a security & privacy researcher, not an official representative of these projects. The following is a theoretical exploration based on public knowledge and cryptographic assumptions. I could be wrong on some details.Image
@zcash uses high-level zero-knowledge proofs—originally zk-SNARKs, now the Halo2 architecture—to obscure sender, receiver, and amounts in shielded transactions.

The theoretical end-goal: make every note indistinguishable, enabling a truly private ledger.
Halo2 uses polynomial commitments (like KZG) and inner-product arguments for succinct, recursive proofs. With O(log n) scaling in verification, it manages large ledgers efficiently, without the need for a post-hoc trusted setup. This sets a robust foundation for theoretical privacy at scale.

iOS vs. GrapheneOS

In terms of #privacy and #security, GrapheneOS absolutely crushes iOS on so many levels. A few awesome features are listed here.

🧵
@GrapheneOS is an #opensource operating system based on AOSP, focused on #security and #privacy. It is designed to be used on mobile devices, and includes features such as verified boot, sandboxing, and exploit mitigations.
It also includes the ability to use different encryption methods, and the ability to use VPNs and the Tor network to enhance #privacy.

GrapheneOS is geared more towards security-conscious and privacy-conscious users and has a #opensource ecosystem.

Be safer online in 2023 by following these basic tips.

#CyberSecurityAwareness #cybersecurity #privacy

🧵
Check if your emails, phone numbers, passwords, etc. have been breached on @haveibeenpwned / Firefox Monitor.

More info -

Use secure passwords that are unique for every account you have. Do not include PII in your passwords, such as your name or birthdate.

I suggest using a passphrase with at least five words or a complex password with at least 25 characters. A password manager can come in handy.

Why is data so important? Well explained by @harari_yuval

More data, more power.

Where is our data going? Who’s handling our data? Do they have our consent to use it in a particular way?
Value of data is increasing as we speak.

Twitter vs. Mastodon - how do they work?
Credit: @alexxubyte Alex Xu ,@bytebytego

Centralized vs. #Decentralized Social Network

#TwitterTakeover #TwitterMigration #mastodon

🧵 Twitter vs Mastodon
Trump's brand-new social network 'Truth Social' used Mastodon's code. @joinmastodon

Reference: blog.joinmastodon.org/2021/10/trumps…
Mastodon's revenue is not dependent on advertisers like other social media companies like Facebook, Instagram, Twitter, Snapchat, Tiktok, etc. The ad-based revenue model isn't necessarily good in all cases as ads=tracking leads to the users -> product and advertisers -> customers Credit: Four Week MBA

My humble suggestions to improve @Twitter

@elonmusk
🧵
- Twitter algorithm #opensource
(What does the algorithm do exactly? Is it harmful or actually doing any good? No algorithm - sort by timeline)

- Try our best to achieve free speech (not a fan of censorship, but we also have to follow the law of the land)
- Give users more privacy options so it can also be a platform for highly targeted individuals like journalists, whistle-blowers, activists, etc.

- Community guidelines to be run by the Twitter community, not by a small group of people at the top (decentralized decisions)
