INTRODUCING SUPPLY CHAIN ATTACK CAMPAIGNS TRACKING IN THE SOCKET DASHBOARD

Socket launched a Threat Intel page with campaign tracking that identifies whether organizations are affected by active supply chain attack campaigns targeting package registries like npm. The feature groups related malicious packages under single campaigns (such as Shai-Hulud and Contagious Interview), displays Safe/Impacted status for each organization, and provides direct links to affected repositories with ecosystem filtering for npm, PyPI, and Maven. Security teams can immediately assess exposure to coordinated attacks without cross-referencing advisories or running custom scripts.

HONG KONG ISSUES CODE OF PRACTICE UNDER THE PROTECTION OF CRITICAL INFRASTRUCTURES (COMPUTER SYSTEMS) ORDINANCE

Hong Kong's Office of the Commissioner of Critical Infrastructure issued a Code of Practice on January 1 that translated the Protection of Critical Infrastructures Ordinance into specific compliance requirements for critical infrastructure operators. The CoP establishes criteria for Critical Computer System designation (including SCADA and industrial control systems), defines material change notification triggers, mandates security audits and management plans, and clarifies incident reporting timelines—12 hours for serious incidents affecting service levels or causing data breaches, and 48 hours for other security incidents. Critical infrastructure operators should treat the CoP as the operative compliance benchmark and implement structured governance programs aligned with its technical baselines, security audit requirements, and incident response protocols to meet supervisory expectations.

A NOVEL SIDE-CHANNEL ATTACK THAT UTILIZES MEMORY RE-ORDERINGS

Memory DisOrder is a timerless side-channel attack that exploits memory re-orderings in relaxed memory models to infer cross-process activity on mainstream CPUs (X86/Arm/Apple) and GPUs (NVIDIA/AMD/Apple). The technique demonstrated covert channels achieving up to 16 bits/second with 95% accuracy on Apple M3 GPU, reliable DNN architecture fingerprinting, and potential throughput of nearly 30K bits/second on X86 CPUs when exploiting low-level system details. Organizations should monitor for emerging mitigations as this vulnerability class, which affects parallel processing units, becomes better understood.

PHISHING CAMPAIGN ZEROES IN ON LASTPASS CUSTOMERS

An ongoing phishing campaign targeting LastPass customers began around January 19, using LLM-crafted emails with plausible subject lines urging users to "back up their vaults" before scheduled maintenance. The phishing emails direct victims to credential-harvesting sites designed to capture master passwords, potentially compromising entire password vaults. Organizations should alert users to verify email sender addresses, enable MFA on password managers, and report suspicious LastPass-branded emails.

MY FAVORITE NEW SOCIAL NETWORK

People are moving away from public feeds toward small, intentional email networks known as ‘Heartbeat Emails'. These are periodic, semi-personal updates sent to a curated group of people you genuinely want to stay connected with. They're designed to invite replies rather than broadcast status.

CONSUMERS SPENT MORE ON MOBILE APPS THAN GAMES IN 2025

Consumers spent more on non-game apps than games for the first time last year. App spending reached $85B, up 21% YoY, as AI app revenue more than tripled and usage surged. Users spent far more time in these apps rather than simply downloading more of them. AI assistants led the charge, dominated by ChatGPT, Gemini, and DeepSeek. Mobile emerged as the primary access point for AI, especially in the US. AI has moved from novelty to daily utility.

RESULTS FROM UNGATED CONTENT

After spending $15K to generate just 106 low-quality ebook leads, a team realized gated content was blocking real engagement. Only 3% of visitors filled out the form, so they ungated everything and stopped reporting on leads. They measured cost per engagement and focused on pipeline and revenue. One year later, demo requests rose 265%, pipeline grew 242%, and cost per engagement dropped 90%. By letting people opt in only when they wanted the content, the team showed ungating drives far more business impact than chasing low-quality leads.

LET PEOPLE KEEP THEIR RETURNS

Letting customers keep low to moderately-priced items while issuing a full refund increases repeat purchase intent and brand sentiment, making customers up to 2x more likely to buy again. Across 9 experiments, returnless returns drove 24.6% higher ratings, up to 30.1% more positive reviews, and 30% higher perceived value compared to standard return policies. The effect is stronger when it is framed as customer convenience or an environmental choice and when customers are encouraged to donate items, but it weakens if proof is required, causing 20% less positive word of mouth. The approach works best for frequently repurchased and lower-cost items, while profitability depends on category, price, and fraud controls.

HOW TO MANUALLY TRACK SENTIMENT

Understanding brand sentiment does not require expensive tools. Collect 100 comments from influencer posts, reposts, and related social channels like Reddit, Facebook groups, or TikTok. In a spreadsheet, create columns for positive, neutral, and negative. Positive includes intent to buy, or tagging friends. Neutral covers mentions or facts. Negative includes skepticism, complaints, or comparisons. Count comments in each column and divide by the total to get a sentiment score.

YOUTUBE CEO NEAL MOHAN'S BIG IDEAS FOR 2026: MORE SUPERSTAR CREATORS AND TRANSPARENCY, LESS AI SLOP

Neal Mohan frames the year as an inflection point. He's drawing a clear line against low-quality “AI slop”, spam, and deepfakes. YouTube plans to increase transparency through labeling and likeness protections and continue treating creators as full-fledged studios rather than casual users. The goal is to balance openness and innovation with a viewing experience people actually want to spend time in.

UX STRATEGIST: THE ONLY JOB WHERE SAYING ‘IT DEPENDS' IS CONSIDERED EXPERTISE

UX strategy often stalls product progress because it avoids hard decisions and defaults to more research. Many UX strategists charge $120 to $180 per hour to produce frameworks and PDFs that conclude further validation is needed. In contrast, direct fixes based on obvious user pain points cut support tickets by 68% in one case and raised activation by 23% in another. The real cost is not just money but months of delay while products stay broken and teams wait for clarity that never arrives.

Musk, an OpenAI co-founder, is seeking up to $134 billion in damages, with a jury trial scheduled for this Spring. The files reveal how Microsoft pursued, rebuffed, and backed OpenAI at various moments over the past decade. The previously undisclosed emails, messages, slide decks, reports, and deposition transcripts show how Microsoft ultimately shaped the course of the lab that launched the generative AI era.

I'M ADDICTED TO BEING USEFUL

AGENTIC AI AND THE MYTHICAL AGENT-MONTH

The concept of 'Scalable Agency', where a developer could theoretically spin up thousands of agents to complete tasks faster, relies on a flawed assumption that software engineering is an embarrassingly parallel task. Context loading is not the same as common knowledge, and reading tokens is not the same as understanding the causal chain of changes across a system. Adding manpower to a late software project makes it later. Multi-agent systems do not escape this law, they simply hit the wall of state-space explosion faster than humans do.

DEEPMIND CEO SAYS CHINESE AI FIRMS ARE 6 MONTHS BEHIND THE WEST

Google DeepMind's CEO, Demis Hassabis, says that Chinese AI companies remain around six months behind the frontier AI of the leading Western labs. He says the response to DeepSeek's R1 model last year was a massive overreaction and that while Chinese firms are very good at catching up to the frontier, they have yet to show they can innovate beyond that. Some of the barriers to Chinese AI development are set to come down as the Trump administration is easing a ban on advanced AI chip exports to China. Sales of the most advanced AI processors will remain blocked on national security grounds.
