Ghost ransomware actors, identified as operating from China, have been targeting unpatched systems and stolen credentials to infiltrate networks, encrypt data, and demand ransom payments. Patching and vulnerability management Apply timely security updates to operating systems, software, and firmware.
Encryption scrambles data to make it unreadable to those without decryption keys. Proper use of encryption preserves secrecy and radically lowers the potential damage of a successful cybersecurity attack. Encryption algorithm types will provide an overview of the mathematical algorithms used to encrypt data (AES, RSA, etc.),
HideezKey- This is a deep-dive into a nice concept for a security token & passwordmanager that turned into a horrible product due to lack of proper R&D and Threat Modeling. This will help me later in the case I will be able to obtain a firmware that eventually is encrypted (i.e. known-plaintext attack).
When creating passwords, use at least 12 characters, combining uppercase and lowercase letters, numbers, and special symbols. Using a passwordmanager can help you generate and store complex passwords without remembering each one. Use encrypted messaging apps like Signal or WhatsApp for private communications.
In the case of the Nvidia breach, LAPSUS$ claimed it was mainly after the removal of the lite hast rate (LHR) limitations in all GeForce 30 series firmware—apparently all to help out gamers and the mining community. If you recognize one or more of them we would encourage you to not only change them, but also to start using a passwordmanager.
When your phone or computer alerts you to an available software or firmware update, pay attention and do what you’re asked to do immediately (as opposed to clicking “Remind me later”) because many of these patches are security-related. Consider using a passwordmanager. Or use a passwordmanager.).
update, Apple introduced “Advanced Data Protection,” which finally introduced end-to-end encryption (E2EE) for most items backed up or stored in iCloud. Enabling end-to-end encryption (Advanced Data Protection for iCloud). encrypted email providers. Enabling end-to-end encryption (Advanced Data Protection for iCloud).
To protect against those threats, a Wi-Fi Protected Access (WPA) encryption protocol is recommended. WPA2 is a security protocol that secures wireless networks using the advanced encryption standard (AES). WEP and WPA are both under 4%, while WPA2 commands a 73% share of known wireless encryption connections.
Encryption: End-to-end encryption isn’t enabled by default for doorbells but should be activated. Privacy and Passwords: Two-step verification is done by default, but multi-factor authentication (MFA) is recommended. Encryption: What’s the deal? Is Ring secure for UK users?
Because LDAP extends to IoT devices, of which there are many more than IT devices, organizations running LDAP need to encrypt traffic using TLS certificates on IoT devices, keep the firmware up to date, and apply proper passwordmanagement. Make sure that you sanitize any input before it gets passed to the daemon.
Use the administrator account only for maintenance, software installation, or firmware updates. Opt for strong, hard-to-crack passwords. Consider using dedicated passwordmanager apps. Attention should be paid to protecting routers and updating their firmware.
Ensure all backup data is encrypted, immutable (i.e., Use long passwords (CISA says 8 characters, we say you can do better than that) and passwordmanagers. Store passwords using industry best practice password hashing functions. Implement password rate limits and lockouts.
Control Inbound and Outbound Traffic: Configuring firewall rules to manage both incoming and outgoing traffic is an important defense against cyber threats, preventing unauthorized access and malicious software from stealing data. Regularly update router firmware to patch vulnerabilities and close potential avenues of attack.
Both use the.kitty or.crypted file extension for encrypted files. Ensure all backup data is encrypted, immutable (i.e., Use long passwords (CISA says 8 characters, we say you can do better than that) and passwordmanagers. Store passwords using industry best practice password hashing functions.
A VPN provides a secure internet connection, ensuring your browsing data is encrypted for maximum privacy and security. Keep them organized by writing them down and storing them in a safe place offline and offsite or use a passwordmanager. Most manufacturers of IoT enabled devices update their firmware frequently.
Encrypt backup data to ensure the data infrastructure’s immutability and coverage. Password Policies: Enforce NIST password policy requirements, such as lengthier passwords and the use of passwordmanagers. Password suggestions should be disabled, and frequent password changes should be avoided.
Improved Passwords: Organizations seeking improved security will typically increase password strength requirements to add complexity or more frequent password rotation. Passwordmanagers aid users in meeting more stringent requirements, and can enable centralized control as well.
Additional security all organizations should consider for a modest investment include: Active directory security : Guards the password storage and management system against attack for Windows, Azure, and other equivalent identity management systems. CrowdStrike: Observed politically affiliated ransomware attacks against Israel.
Phishing attacks: Deceptive techniques, such as fraudulent emails or websites, trick individuals into revealing sensitive information like credit card and payment information, passwords, or login credentials. This often causes significant disruptions and data loss to the company.
A pivotal moment came when the FBI obtained over 7,000 decryption keys, allowing victims to unlock their encrypted data for free. Despite these setbacks, LockBit attempted to maintain its operations, quickly adapting by changing encryption methods and shifting its leak site strategy.
firmware (hard drives, drivers, etc.), However, some patches, particularly for infrastructure, firmware, or less common software may not be automatable. While this eliminates many headaches, it does not scan for misconfigurations and may not support other critical updates such as IT infrastructure (routers, firewalls, etc.),
Have regular conversations about cybersecurity in manager and employee one-on-one meetings. Install software like passwordmanagers to help employees manage their credentials safely. It’s critical for network administrators to patch firmware vulnerabilities immediately after learning of them.
