VPN used for VR game cheat sells access to your home network
- Teenagers have found a way to cheat in the virtual reality game Gorilla Tag by using a VPN to change their location and gain an advantage.
- The VPN app, Big Mama VPN, is not only used for in-game cheating but also sells access to users' home internet connections.
- Buyers of Big Mama VPN can hide their online activity by piggybacking on the VR headset's IP address.
- While the cheating itself may be relatively harmless, the selling of users' home internet connections raises privacy concerns.

AES Encryption Keys (password hashing)
- AES Encryption Keys (password hashing) relies on a password of sufficient length and the non deterministic factor of indistinguishable random data. However, passwords as user inputs do not make for good encryption keys. To use passwords for encryption, a key derivation function must be applied which generates derived keys. Key derivation functions work by utilizing unique random salt to make pre-calculated rainbow tables infeasible. Furthermore, the salt should be stored with the password to ensure it is public, thus rendering the hash with the same password looking different. Weak keys refer to cryptographically secure generated keys, which makes an encryption algorithm vulnerable to an exploit.
- For good encryption keys, a minimum length, determined by the AES encryption algorithm, is required. AES+CBC encryption necessitates a minimum length of 16 bytes, while AES+GCM can work with 12 bytes, although 16 bytes is suggested. To use passwords for encryption, a Key Derivation Function (KDF) is required to generate derived keys like argon2, bcrypt, and scrypt. Key derivation functions must be slow and some like argon2 are designed to take up a substantial amount of memory such that calculations on GPUs are not possible, to deter brute force attacks against offline stolen data.
- Argon2 is considered the best KDF to use for password key derivation, with Argon2id being its most secure mode. Unfortunately, allot of encryption starts with user-supplied passwords, which are not random inputs of sufficient length making them 'easily' guessed by a bruteforce attack. To protect passwords from such attacks, the password's hash must not be stored and must be encrypted with the hash itself. Although offline bruteforce attacks on remote login systems are improbable, offline attacks on stolen data can be quite effective.
- Weak keys, although generally not a concern in AES encryption, can pose a problem in the AES+GCM mode, which has several published papers on weak keys and can make the encryption algorithm vulnerable to an exploit. Ultimately, the GCM mode would best be used for anything with short-lived keys and not for disk encryption where keys and ciphers live longer. Another noteworthy point is that although salts are not secret and are public, they make pre-calculated rainbow tables infeasible and as such the salt should be stored with the password.
- In conclusion, the use of derived keys in KDFs is a more secure way to encrypt data since passwords as user inputs do not make for good keys. However, even with a decent hashing algorithm and a random unique salt, it is still a possibility that your hash and salt may be exposed. As such, unique and strong passwords are recommended to prevent such password cracking attempts.

Tips to keep your smartphone just as safe as a government official’s
- The Cybersecurity and Infrastructure Security Agency (CISA) has issued a set of guidelines to protect smartphones. Here are some tips from CISA to keep your smartphone just as safe as a government official.
- CISA’s first general advice for communications is to use end-to-end encrypted services. iPhone’s default iMessage pipeline and the RCS protocol championed by Google for its Messages app on Android are both end-to-end encrypted.
- Enabling hardware-based or on-device authentication for identity verification is the next line of defense. Go ahead and enable them if carrying a physical FIDO hardware key, like one from Yubico, sounds like too much of a hassle.
- Another crucial suggestion by CISA is that you should ditch SMS-based multi-factor authentication, as they are prone to various kinds of attacks. Instead, switch to authenticator apps.
- If an authenticator app is not an option for your work or productivity flow, rely on a password management app instead of the inconvenient (and hack-prone) route of remembering a dozen passwords.
- Moreover, if you live in a country where carrier accounts form the backbone of your cellular usage, set up a strong password for that SIM account.
- Use a VPN for your internet surfing activities.If possible, pay for one instead of going the free VPN route. We have detailed the steps to keep your app permissions in check for both Android and iOS.
- If you sense malware activity on your iPhone, enable Lockdown Mode and reach a law enforcement authority.
- Google offers a Security Checkup dashboard for all connected devices. I suggest that you spend a few minutes flicking some toggles and clearing the security alerts in there.
- Taking the time to follow a few tips can drastically reduce your risks.
