Fun with Timing Attacks: Exploiting Subtle Timing Differences to Crack Passwords

2025-01-18

This article unveils a clever attack technique known as a timing attack. By repeatedly calling a seemingly secure function, `checkSecret`, and precisely measuring its execution time, an attacker can infer the secret value. Even if `checkSecret` has no obvious vulnerabilities, its internal 'early exit' mechanism causes partially matching guesses to take longer, leaking information. The article details how to exploit this timing difference, combining Thompson Sampling and a Trie data structure to efficiently guess passwords, and discusses handling the complexities of network noise. Ultimately, the article stresses the importance of avoiding direct comparison of sensitive data, recommending the use of hashes or other secure algorithms, and implementing robust rate limits.

Superbloom: How Connection Technologies Tear Us Apart

Superbloom: How Connection Technologies Tear Us Apart

Nicholas Carr's new book, *Superbloom*, examines how modern connection technologies—cell phones, the internet, social media, etc.—impact individuals and society. Carr argues these technologies aren't inherently evil but cause negative consequences due to our misconceptions about communication and ourselves. He uses the 2019 Los Angeles poppy bloom event to illustrate how information overload and social media's amplification effect lead to chaos and negativity. The book traces the history of communication technologies, highlighting how they've always been accompanied by supernatural imaginings, and raises concerns about anonymity, power, and information veracity. Carr critiques technological optimism, arguing that information overload hasn't led to a more democratic or rational society but has instead exacerbated social divisions. He contends that social media's design leverages cognitive biases, exacerbating information fragmentation and fast-paced thinking, ultimately resulting in a 'hyperreality' where truth is indistinguishable from falsehood. Carr calls for a return to reality, resisting information overload, and proposes potential solutions, such as increasing the friction cost of information dissemination.

Sophisticated Phishing Attack Leverages VPN Access

2025-01-29

The University of Toronto's Computer Science department was hit by a highly sophisticated phishing attack. The attacker spoofed a departmental email address, successfully phishing a user's password. Alarmingly, the attacker used the stolen credentials to quickly register the user for the department's VPN, then used the internal-only SMTP gateway to send spam. This demonstrates pre-attack reconnaissance of the target's VPN and email environment, highlighting increasingly advanced attack techniques and the need for robust cybersecurity defenses.

Embedding User-Defined Indexes in Apache Parquet Files: No More External Indexes!

2025-07-15

It's a common misconception that Apache Parquet is limited to basic statistics and Bloom filters. This post reveals how to embed custom indexes directly into Parquet files without breaking compatibility. By leveraging footer metadata and offset-based addressing, you can add indexes like distinct value lists for specific columns, dramatically improving query performance, especially for highly selective predicates. The authors detail the mechanism and provide a practical example using Apache DataFusion, showing how to serialize, store, and read these custom indexes. Say goodbye to the complexities and risks of external indexes!

Egyptian Fractions: A Journey Through Ancient Mathematics

2024-12-18

This article explores the fascinating world of Egyptian fractions, a unique mathematical system used by ancient Egyptians. Unlike modern fractions, Egyptian fractions only use unit fractions (fractions with a numerator of 1) and all denominators must be distinct. The article traces the history of Egyptian fractions, focusing on the Rhind Mathematical Papyrus, and examines their practical applications, such as fairly dividing resources. It introduces the greedy algorithm for finding Egyptian fractions and methods for finding the shortest ones, also exploring related unsolved mathematical problems, including the Erdős–Straus conjecture.

Intel Quietly Slashes Xeon 6 CPU Prices by Up to $5,340

Intel Quietly Slashes Xeon 6 CPU Prices by Up to $5,340

Intel unexpectedly slashed prices on its latest Xeon 6 'Granite Rapids' processors, just four months after their release. The flagship model now costs $12,460, a $5,340 drop. This makes Intel's Xeon 6 CPUs cheaper than AMD's EPYC processors, both in absolute terms and per-core. While unannounced officially, the price cuts are reflected in Intel's online database. Reductions vary by model, reaching up to 30% for some, with certain models undercutting AMD's per-core pricing. This move may be a response to declining market share or an attempt to boost sales. However, these prices are based on Intel's Recommended Customer Price (RCP) for 1,000 units; large-scale buyers will likely have negotiated different prices.

The Secret Weapon for Diffusing Toxic Meetings: Naming What's Happening

This article reveals a powerful technique for resolving conflict in meetings: simply stating what's happening in the room. The author argues that many meetings devolve into unproductive arguments due to clashing priorities, emotions, and unspoken tensions. Instead of engaging in the conflict, the solution is to directly name the collective experience, e.g., "I'm sensing a lot of frustration in the room." This disrupts negative patterns, creates shared awareness, and paves the way for more productive communication and problem-solving. The article provides tactical tips, including using "I" statements, avoiding singling out individuals, and knowing when to escalate.

Stop Chasing Tech Trends: Focus on What Matters

Programmers often get bogged down in technology choices, debating which language or framework is superior. But the truth is, users don't care! They won't notice those extra 10 milliseconds you saved, nor will their experience magically improve because you're using the latest JavaScript framework. What truly matters is your focus on the product and user needs. Every programming language and framework excels in specific contexts, but technical decisions alone won't define your product's success. Instead of chasing hype, choose technologies you're familiar with, enjoy working with, and that challenge you to improve daily. Finding the right balance between tech choices and product value is key to building something truly impactful.

America's Healthcare System: A Total Breakdown, Beyond Insurance Companies

The American healthcare system is broken, and the problem extends far beyond insurance companies. An oncologist argues that pharmaceutical firms, PBMs (pharmacy benefit managers), the FDA, CMS, hospitals, and doctors all share responsibility. Pharmaceutical companies push unproven drugs, PBMs profit excessively, regulators are lax, hospitals charge exorbitant fees and engage in predatory practices, and doctors order unnecessary tests and treatments. While insurance companies are frustrating, they are a scapegoat for a larger systemic issue. The author calls for sweeping reforms of the FDA and CMS to end corporate capture of regulatory agencies, addressing the high costs and inefficiency of the US healthcare system. The recent assassination of an insurance CEO highlights public frustration with the system.
