“The new normal” as cyber-spies navigate pandemic

The Covid crisis has reshaped the cyber-threat landscape around the globe.

There may not have been a significant increase in the volume of cyber-attacks, but countries have pursued new targets, pushed boundaries and taken advantage of their adversaries working from home, according to cyber-security experts.

Intelligence analysts say some of the normally less active states have begun using cyber-espionage more aggressively and they have seen allies target each other for information for the first time. “It’s a free-for-all out there – and with good reason – you don’t want to be the intelligence agency that doesn’t have a good answer for what’s going on,” says John Hultquist, director of threat analysis at Mandiant

Home workers are regarded as particularly vulnerable to cyber attacks

Book of the month

Learn Security Engineering

Security engineering, to me, is the discipline of building secure systems. Ultimately, I hope to learn how to systematically secure anything — whether it’s a computer network or medieval castle.

I tried for several years to read Ross Anderson’s book, and eventually I realized it wasn’t structured correctly for me. This learning path is, and hopefully it is for you, too

Babylon Health admits GP app suffered a data breach

Babylon Health has acknowledged that its GP video appointment app has suffered a data breach.

The firm was alerted to the problem after one of its users discovered he had been given access to dozens of video recordings of other patients’ consultations.

A follow-up check by Babylon revealed a small number of further UK users could also see others’ sessions.

The firm said it had since fixed the issue and notified regulators

Here’s what that Capital One court decision means for corporate cybersecurity

When a judge ruled last month that Capital One must provide outsiders with a third-party incident response report detailing the circumstances around the bank’s massive data breach, the cybersecurity world took notice.

The surprise decision, in effect, determined that Capital One would need to provide the forensic details — warts and all — about the hack to attorneys representing a group of customers suing the bank. It’s the kind of report that, if made public, could highlight technical and procedural failures that made it possible for a single suspect to allegedly collect gigabytes of data about 100 million people from a bank with $28 billion in revenue

Updated Specification Available for Universal Plug-and-Play Protocol Vulnerability

A flaw in the Universal Plug-and-Play Protocol (UPnP) protocol could be exploited to launch distributed denial-of-service (DDoS) attacks, exfiltrate data, and scan internal ports. Dubbed CallStranger by the researchers who created proof-of-concept exploit code, the issue affects billions of Internet of Things (IoT) devices. An updated specification is available.

Research of the week

Featuring – Availability Attacks against Neural Networks

Energy-Latency Attacks on Neural Networks shows how to find adversarial examples that cause a DNN to burn more energy, take more time, or both. They affect a wide range of DNN applications, from image recognition to natural language processing (NLP). Adversaries might use these examples for all sorts of mischief — from draining mobile phone batteries, though degrading the machine-vision systems on which self-driving cars rely, to jamming cognitive radar.

So far, our most spectacular results are against NLP systems. By feeding them confusing inputs we can slow them down over 100 times. There are already examples in the real world where people pause or stumble when asked hard questions but we now have a dependable method for generating such examples automatically and at scale. We can also neutralize the performance improvements of accelerators for computer vision tasks, and make them operate on their worst case performance

Backstabber’s Knife Collection: A Review of Open Source Software Supply Chain Attacks

A software supply chain attack is characterized by the injection of malicious code into a software package in order to compromise dependent systems further down the chain. Recent years saw a number of supply chain attacks that leverage the increasing use of open source during software development, which is facilitated by dependency managers that automatically resolve, download and install hundreds of open source packages throughout the software life cycle. This paper presents a dataset of 174 malicious software packages that were used in real-world attacks on open source software supply chains, and which were distributed via the popular package repositories npm, PyPI, and RubyGems. Those packages, dating from November 2015 to November 2019, were manually collected and analysed. The paper also presents two general attack trees to provide a structured overview about techniques to inject malicious code into the dependency tree of downstream users, and to execute such code at different times and under different conditions. This work is meant to facilitate the future development of preventive and detective safeguards by open source and research communities

Vulnerabilities of various severity levels, by industry

  • Hackers can attack users in 9 out of 10 web applications. Attacks include redirecting users to a hacker-controlled resource, stealing credentials in phishing attacks, and infecting computers with malware.
  • Unauthorized access to applications is possible on 39 percent of sites. In 2019, full control of the system could be obtained on 16 percent of web applications. On 8 percent of systems, full control of the web application server allowed attacking the local network.
  • Breaches of sensitive data were a threat in 68 percent of web applications. Most breachable data was of a personal nature (47% of breaches) or credentials (31%).
  • 82 percent of vulnerabilities were located in application code.
  • The average number of vulnerabilities per web application fell by a third compared to 2018. On average, each system contained 22 vulnerabilities, of which 4 were of high severity.
  • One out of five vulnerabilities has high severity

A survey of recent iOS kernel exploits

I recently found myself wishing for a single online reference providing a brief summary of the high-level exploit flow of every public iOS kernel exploit in recent years; since no such document existed, I decided to create it here.

This post summarizes original iOS kernel exploits from local app context targeting iOS 10 through iOS 13, focusing on the high-level exploit flow from the initial primitive granted by the vulnerability to kernel read/write. At the end of this post, we will briefly look at iOS kernel exploit mitigations (in both hardware and software) and how they map onto the techniques used in the exploits

Security Analysis of the Democracy Live Online Voting System

Democracy Live’s OmniBallot platform is a web-based system for blank ballot delivery, ballot marking, and (optionally) online voting. Three states — Delaware, West Virginia, and New Jersey — recently announced that they will allow certain voters to cast votes online using OmniBallot, but, despite the well established risks of Internet voting, the system has never been the subject of a public, independent security review.

We reverse engineered the client-side portion of OmniBallot, as used in Delaware, in order to detail the system’s operation and analyse its security. We find that OmniBallot uses a simplistic approach to Internet voting that is vulnerable to vote manipulation by malware on the voter’s device and by insiders or other attackers who can compromise Democracy Live, Amazon, Google, or Cloudflare

##Securing Your GraphQL API from Malicious Queries

With GraphQL you can query exactly what you want whenever you want. That is amazing for working with an API, but also has complex security implications. Instead of asking for legitimate, useful data, a malicious actor could submit an expensive, nested query to overload your server, database, network, or all of these…

##Thoughts On Zero Trust

By Petko Petkov

I strongly believe that regardless of our level of technology and security maturity, every decision must be tested by removing all assumptions and thinking in terms of first principles. In other words, before we take an action we must test our assumptions first. Only then, once we face the ultimate and indisputable truth, we are safe to proceed
