MUST KNOW Social Media Safety Tips for all

#cybersecurity #privacy #SecurityAwareness

🧵
Don't share too much Personally Identifiable Information(PII).

Hackers tend to make customized profiles for their victims so that they can perform social engineering attacks on them. It can also lead to identity theft. Think twice before sharing anything online.
Use a strong password/passphrase for all your accounts. This should not contain any words from the dictionary and should not be linked to your personal information. It is highly recommended to use a good password manager like @Bitwarden. Going #passwordless is even better.
Best option: Use @Yubico

Why YubiKey?
- Hardware Authentication + Biometric/Pin => super secure
- Phishing Resistant
- Crush and IP68 Water Resistant

Using an authenticator app is much more secure than SMS for your OTPs.

Twitter-specific security tips:

- Enable Two-Factor Authentication

- Disable Direct Message (depends on how you want to handle it, usually recommended for accounts having lot of followers)

- Enable Quality Filter

- Review Apps and Sessions regularly

- Disable Tweet Location
LinkedIn-specific security tips:

- Turn off third-party data sharing

- Enable Two-Step Verification

- Review Partners and Services regularly

- Do not reveal your personal or business email and phone numbers
YouTube-specific security tips:

- Enable Restricted Mode

- Pause the data collection for YT i.e., search and video history

- Disable the quick purchases feature

- Filter comments for your YT videos
Its better to avoid all Meta products. Delete your accounts if you can. But if you are still using it, follow the must use security tips.

Facebook-specific security tips:

- Make your profile private

- Check 'Where you are Logged In' regularly

- Enable 'Unrecognised Login Alerts'

- Enable Two-Factor Authentication

- Add 3-5 trusted friends for account recovery

- Review Apps Permissions
Instagram-specific security tips:

- Make your account private

- Enable Two-Factor Authentication

- Review & Revoke Third-Party Access

- Block Unknown Followers
Beware of Fake Social Media Friends

- Never accept friend request / follow request from someone you don't know (usually happens in Facebook and Instagram)

- Never click on Links sent by someone you do not trust

- Keep location services turned off
Save yourself from Identity Theft

- Do not use Social Media or do any financial transaction while using Public WiFi, if you had to - use a VPN like @ProtonVPN, @mullvadnet, @ivpnnet

- Never use unencrypted sites (http, should be https)

- Do not share confidential information
Bonus tips for Apple users:

- Use Apple Login wherever possible
[More secure]

- Hide your email id while signing in (generates random email id with iCloud)

- Use Do Not Track Feature

Settings -> Privacy -> Tracking -> Switch off Request to Track

There are Login with Google and Facebook too. But I do not trust them. Try to reduce your dependence on companies that have bad track record in protecting user #privacy.

This is called "OAuth Authentication"

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?

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

- 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)
