Welcome to this week’s edition of the Threat Source newsletter. Our goal is to get accurate threat intelligence to our audience as quickly as possible, with all the context you need to ask the right questions of your own environment: How at risk are we from this threat? Are we prepared for it? And what can we do about it? What you don’t often see is all the... well, frankly, “mess” involved in producing it. All the dead ends we followed until we could confirm those ends were as dead as a…
Infostealers can expose far more than passwords, including authenticated sessions that may let attackers bypass MFA. Flare explains how defenders can prioritize compromised identities, determine whether stolen access is still usable, and respond before it leads to account takeover. [...]
CISA and the Group of Seven (G7) Cyber Security Working Group released Preparing for the Post-Quantum Era: A Call to Action highlighting the urgent need for organizations and governments to begin transitioning to post-quantum cryptography (PQC) to protect sensitive data, authentication systems, and critical assets from emerging quantum computing threats. The G7 Cyber Security Working Group’s call to action outlines five priorities for a successful transition to PQC: Raising awareness of quantum…
First, the good news: If you use a Linux-based operating system, you may not be asked your age in a few months. The bad news is that Windows, macOS, iOS, and Android users in California will be. California has passed a law that requires a range of operating systems to start collecting your age when you first set them up. Under the state’s Digital Age Assurance Act (DAAA), signed into law in October 2025, Windows, macOS, iOS, and Android will all have to do this from January 1, 2027. Operating…
[This is a Guest Diary by Frank Igbokwe, an ISC intern as part of the SANS.edu BACS program] Honeypot-Omaha is a DShied Sensor located at the Internet Storm Center (ISC) that is set up as a decoy for the original target and deployed over the internet. It is a flawed and very vulnerable system that was intentionally designed to attract threat actors with malicious intents. I view it as a massive log aggregator that collects data that an analyst like myself can then analyse, hypothesize,…
In a tech support scam, criminals pretend to work for a trusted technology or security company. They claim there is a problem with your device, software, subscription, or account, then try to persuade you to pay them, share personal information, or give them remote access to your computer. These scams used to rely mainly on browser locks and fake virus warnings. Now, scammers use many more ways to reach people, including websites and platforms they trust. How tech support scams reach you As…
Ransomware resilience requires more than backups or endpoint detection alone. Acronis outlines six capabilities MSPs should test across client environments, from reducing exposure and detecting attacks to preserving recovery points and restoring operations quickly. [...]
Developed by CISA, the Federal Bureau of Investigation, and international partners, this guidance describes how organizations can plan and execute clear, timely, accurate, and audience-appropriate communications during IT and operational technology (OT) outages. Whether caused by cyber threat actors, human error, equipment failure, or natural hazards, service outages can create disruption and societal panic even without speculation from end users and the public as added factors. Outages at one…
You might tell an AI chatbot secrets that you wouldn’t divulge to your closest friends. If you do, though, beware: They could end up as evidence in court. An article in the Washington Post this week highlighted several cases in which people had discussed sensitive information with AI systems like Claude and ChatGPT, only to have their conversations obtained by prosecutors or opposing lawyers. Lawyers can get access to your chatbot conversations from AI services like ChatGPT because they aren’t…

In this article What is the Cybersecurity Incident Response Readiness Workshop?Our approach: How we assess your maturityLearn more Cybersecurity incidents can unfold in hours, but response plans often fail at the point of execution: ownership is unclear, investigation findings is difficult to access, and critical decisions are delayed. That is why incident response cannot be something your organization figures out in real time. The Detection and Response Team (DART) – the Microsoft team that…
File servers remain a critical part of many IT environments, but managing access securely can become complex as permissions accumulate. tenfold Software outlines five best practices for simplifying file server administration and maintaining least-privilege access. [...]
Svaki put kada pristupimo internetu (pretražujemo, komuniciramo, plaćamo online, objavljujemo fotografije ili se prijavljujemo u neku aplikaciju) ostavljamo za sobom trag podataka. Taj trag naziva se digitalni trag i on nas prati mnogo dulje nego što bismo možda željeli. Povratak u školske klupe dobar je trenutak da se podsjetimo kako svjesno upravljati onim što o nama govori internet. Što je digitalni trag i zašto je važan Digitalni trag čini skup svih podataka koje ostavljamo svojim…
Most of a container's vulnerabilities come from the base image. How to harden Docker images, why hardening is ongoing, and how to patch the base you already run. Category: Guides & Best Practices
When quantum computers become generally available, they’ll be able to crack current public-key cryptographic algorithms, putting digitally stored and transmitted data at risk. But the threat already exists, as attackers use the "harvest now, decrypt later" tactic. Discover why building a comprehensive cryptographic inventory and executing a phased operational strategy are critical for protecting your data against quantum computing attacks.Key takeawaysQuantum computing risks are an operational…
Get ready for a phishing trip! Learn about the strategy behind phishing simulations and how it can help your organization build resilience against real phishing threats.
WhatsApp announced on August 25 that more than one billion people now use passkeys to log back into the app. The announcement included two other security upgrades: a stronger two-step verification method and more context for incoming calls from unknown numbers. It marks one of the largest passwordless authentication rollouts to date. Passkeys are now firmly mainstream, with the FIDO Alliance estimating that 5 billion are in use worldwide and 75% of consumers have enabled one on at least one…
Uživatelé iPhonů se stávají terčem nového podvodu vydávajícího se za technickou podporu, který se je snaží oklamat pomocí falešného upozornění na platbu přes Apple Pay.
