What Is A Randomness Beacon?

A decentralized randomness beacon is a service that generates unbiased random numbers by aggregating randomness from multiple independent high entropy sources, providing a public source of randomness. It periodically emits fresh random outputs, known as pulses, which are timestamped and include cryptographic elements for security. The ideal randomness beacon, as formalized by Rabin, aims to regularly produce unpredictable random values that cannot be manipulated by any party.

The Interoperable Randomness Beacons project at NIST seeks to enhance the availability of trusted public randomness as a public utility, facilitating transparency and auditability in services reliant on random processes.

Drand, a distributed randomness beacon daemon written in Golang, enables participating servers to collaboratively produce publicly verifiable random values. Each drand pulse, broadcasted every minute, commits to a 512-bit random string that is time-stamped and signed by NIST. This infrastructure serves as a foundational service for applications, analogous to how Network Time Protocol (NTP) provides timing information.

Overall, decentralized randomness beacons play a crucial role in creating verifiable randomness for numerous real-world applications, including smart contracts and audits, while ensuring integrity in the randomness generation process even in the presence of potentially untrustworthy participants.

Why Is Random Not Cryptographically Secure?

Standard pseudo-random number generators (PRNGs) are inadequate for cryptographic applications; they can be attacked due to their predictable outputs. Computers inherently lack true randomness, leading to insecure randomness when unsuitable functions serve as random sources in critical contexts. For example, JavaScript's Math. random() generates a floating point value from 0 to 1, but it is not cryptographically secure, as it relies on weak algorithms.

Consequently, it should not be used in security-sensitive applications. Issues arise from poor RNG API designs; developers often implement insecure versions inadvertently. Without a cryptographically secure random number generator (CSPRNG), an attacker could exploit predictable output to gain unauthorized access. Secure alternatives, like the JavaScript Crypto Library’s Fortuna or Java’s SecureRandom, are recommended for generating secure random values.

In many applications, such as cryptography or security protocols, reliable randomness is essential. A suitable CSPRNG offers stronger security by generating a higher range of potential outputs, making it harder for attackers to determine initial states. Many libraries, operating systems, or individuals might implement their own RNG functions, which can lead to vulnerabilities. Overall, it is crucial to use cryptographically secure mechanisms for random number generation in contexts where security is paramount.

Is Random.Org Cryptographically Secure?

When it comes to generating cryptographic keys, relying on services like RANDOM. ORG is not recommended for those concerned about security. While fetching numbers via secure HTTP protects them during transit, it doesn’t ensure their integrity or unpredictability. Cryptographically secure alternatives exist, such as cryptographically secure pseudo-random number generators (CSPRNGs), which produce numbers that are extremely hard for third parties to predict.

Despite the issues flagged by RANDOM. ORG, computers possess capabilities to mitigate these concerns effectively. CSPRNGs are considered secure if a computationally-limited attacker lacks an advantage in distinguishing generated outputs. Additionally, standard random number generators, like JavaScript’s Math. random(), are not cryptographically secure. While RANDOM. ORG can generate true random numbers via atmospheric noise, the use of SSL is essential to prevent eavesdropping.

Ultimately, for secure applications involving passwords and tokens, utilizing tools that ensure cryptographic strength is crucial, avoiding reliance on less secure services or methods without ensuring their robustness against potential threats.

Are Online Random Number Generators A Secret Key?

Online random number generators, particularly those based on radioactive or quantum sources, provide high entropy and are unpredictable. However, their lack of guaranteed privacy prevents them from being directly used as secret keys. It's possible to generate up to 500 encryption keys online, supporting 124 cipher types, with options for base64 and hash representations, and results available for download. In cryptography, randomness (or entropy) plays a crucial role, as many algorithms depend on unpredictable numbers for secure key generation.

If an attacker acquires the random numbers used to generate a key pair alongside the public key, they could easily compromise security. Key generation often employs Random Number Generators (RNGs), also referred to as Random Bit Generators (RBGs), which are essential in producing strong keys. Cryptographically Secure Pseudo-Random Number Generators (CSPRNGs) are vital in secure communications like SSL/TLS. For example, in the Diffie-Hellman key exchange, parties generate random nonces to derive a shared secret key.

While Pseudo-Random Number Generators (PRNGs) create a non-truly random sequence from a seed, their predictability poses risks. To enhance security, utilizing hardware wallets that leverage RNGs for private key creation is recommended, alongside ensuring a reliable source of entropy.

What Is Beacon Malware?

Beaconing refers to the process by which malware communicates periodically with a Command-and-Control (C2) server to receive instructions or exfiltrate data. This C2 server contains commands that the malware can execute on the infected machine once it checks in. Essentially, beaconing acts as an indicator of successful malware infection, allowing hackers to issue commands and launch attacks. One notable form of beaconing is linked to Cobalt Strike's "Beacon," which is employed to gain remote access to devices, facilitating ransomware deployment or data theft.

Scammers are increasingly exploiting this technology through extortion scams, claiming to have infected devices with this malware and demanding payment to prevent the release of sensitive information. The beacon, or payload, serves as the implant that gives attackers an entry point into the victim's system, making it an essential element of the malware toolkit and attack strategy. Moreover, beaconing could be a precursor to Distributed Denial-of-Service (DDoS) attacks and is a telltale sign of botnet or peer-to-peer malware infections.

Notably, as this specific malware communicates over various channels, it can disguise its data transfers as innocent traffic. Google has addressed these malicious activities by releasing YARA detection rules for variants of the legitimate Cobalt Strike framework misused by hackers. Overall, understanding malware beaconing is crucial for identifying, protecting against, and responding to these cyber threats effectively.
