Word of the Week Special

“Cloud Snooper”

Attack Bypasses Firewall Security Measures

In the course of investigating a malware infection of cloud infrastructure servers hosted in the Amazon Web Services (AWS) cloud, SophosLabs discovered a sophisticated attack that employed a unique combination of techniques to evade detection and that permits the malware to communicate freely with its command and control (C2) servers through a firewall that should, under normal circumstances, prevent precisely that kind of communication from reaching the infected server.

We have published an in-depth report on the attack, which we have named Cloud Snooper.

Though we discovered the technique in use on AWS, the problem is not an AWS problem per se. It represents a method of piggybacking C2 traffic on a legitimate traffic, such as normal web traffic, in a way that can bypass many, if not most, firewalls.

The complexity of the attack and the use of a bespoke APT (Advanced Persistent Threat) toolset gives us reason to believe that the malware and its operators were an advanced threat actor, possibly nation-state sponsored.

The compromised systems were running both Linux and Windows EC2 instances

-Remember: “Developers – The Lucrative Target for Social Engineers” – Stuart Peck (@cybersecstu)

Developers are a lucrative target for attackers, especially those with public profiles, active on social media, and working on either high profile application and open source projects. The recent attack against an NPM package with malicious code that targeted a popular Bitcoin wallet was subject to a social engineering attack, where the attacker was able to trick the maintainer to hand over ownership, is one of the many examples this is an ever increasing vector This talk looks to explore how exposed some developers are and the impacts this can have either through the supply chain and/or directly to organisations. During this talk will we will demonstrate and discuss:

Open Source Intelligence- recon techniques;

Profiling targets, repos, developer backgrounds, coding style, digital footprint;

If your web server is running on Apache Tomcat, you should immediately install the latest available version of the server application to prevent hackers from taking unauthorized control over it.
Yes, that’s possible because all versions (9.x/8.x/7.x/6.x) of the Apache Tomcat released in the past 13 years have been found vulnerable to a new high-severity (CVSS 9.8) ‘file read and inclusion bug‘—which can be exploited in the default configuration.
But it’s more concerning because several proof-of-concept exploits (1234 and more) for this vulnerability have also been surfaced on the Internet, making it easy for anyone to hack into publicly accessible vulnerable web servers

We issued our billionth certificate on February 27, 2020. We’re going to use this big round number as an opportunity to reflect on what has changed for us, and for the Internet, leading up to this event. In particular, we want to talk about what has happened since the last time we talked about a big round number of certificates – one hundred million.

One thing that’s different now is that the Web is much more encrypted than it was. In June of 2017 approximately 58% of page loads used HTTPS globally, 64% in the United States. Today 81% of page loads use HTTPS globally, and we’re at 91% in the United States! This is an incredible achievement. That’s a lot more privacy and security for everybody

GAO: Critical Infrastructure Must Adopt NIST Cyber Framework
According to a report from the Government Accountability Office (GAO), federal agencies that have the lead in protecting critical infrastructure sectors (sector specific agencies, or SSAs) have for the most part not taken adequate steps to ensure that the sectors they oversee have adopted the National Institute of Standards and Security’s (NIST’s) Framework for Improving Critical Infrastructure Cybersecurity. There are nine SSAs overseeing 16 critical infrastructure sectors. Two SSAs have developed strategies for determining framework adoption in their designated sectors; two others have taken steps toward developing methods. Most of the SSAs have encouraged their sectors to adopt the framework. GAO recommends that NIST develop time frames for completing initiatives, and that the SSAs gather and report in improvements made from framework adoption.
This is urgent. While the SANS Top Twenty are more applicable to the scale of many enterprises, the NIST Cyber Framework is essential for large enterprises that are part of the economic or national security infrastructures

Featuring – Phishing – still a problem, despite all the work

Free NCSC webinar explains how to protect your organisation from scam email campaigns

A wall of fishing lures

Phishing is a threat that most people know about. Emails designed to trick you into clicking a malicious link or divulge passwords and other credentials have become an everyday occurrence. Despite this familiarity, and the multitude of tools and techniques which purport to stop it, phishing remains the number one initial attack vector affecting organisations and individuals.

Unfortunately, there is no silver bullet. Phishing can only be dealt with using multiple complementary measures. This fact leads to some questions: Which measures are most (cost) effective? How should they be implemented? Can they be automated?


The top four Office 365 security pain points

Many novice Office 365 (O365) shops do not know where platform-specific security vulnerabilities lie, or even that they exist. The threats that you are unaware exist do not cause pain until they rise up and bite – then the agony is fierce


Detecting Lateral Movement with WinSCP

RDP is a common way for an attacker to move laterally within an environment. Forensically, when an attacker uses RDP we can use artefacts such as shell bags, link files and jump lists on the remote system to see what was accessed while the attacker was RDPed into the system.
Another way an attacker can access a system remotely is to use a program called WinSCP.  Using
WinSCP, they can browse folders and files on a remote system, copy folder and files back to the system they are currently on, and even search the remote system for files!


Web Browser Privacy: What Do Browsers Say When They Phone Home?

We measure the connections to backend servers made by six browsers: Google Chrome, Mozilla Firefox, Apple Safari, Brave Browser, Microsoft Edge and Yandex Browser, during normal web browsing. Our aim is to assess the privacy risks associated with this back-end data exchange. We find that the browsers split into three distinct groups from this privacy perspective. In the first (most private) group lies Brave, in the second Chrome, Firefox and Safari and in the third (least private) group lie Edge and Yandex

##Securing Firefox with WebAssembly

Protecting the security and privacy of individuals is a central tenet of Mozilla’s mission, and so we constantly endeavor to make our users safer online. With a complex and highly-optimized system like Firefox, memory safety is one of the biggest security challenges. Firefox is mostly written in C and C++. These languages are notoriously difficult to use safely, since any mistake can lead to complete compromise of the program. We work hard to find and eliminate memory hazards, but we’re also evolving the Firefox codebase to address these attack vectors at a deeper level. Thus far, we’ve focused primarily on two techniques:



##Micro Frontends

Good frontend development is hard. Scaling frontend development so that many teams can work simultaneously on a large and complex product is even harder. In this article we’ll describe a recent trend of breaking up frontend monoliths into many smaller, more manageable pieces, and how this architecture can increase the effectiveness and efficiency of teams working on frontend code. As well as talking about the various benefits and costs, we’ll cover some of the implementation options that are available, and we’ll dive deep into a full example application that demonstrates the technique

##And finally, Murdering reality: the spurious spies of fiction

Hollywood lacks the wit and the will to convey the complexities of the secret world.

I recently watched the second season of Amazon’s series Jack Ryan. To be accurate: I managed only the first few episodes. As a career CIA officer, I found the disconnect between my experience running espionage operations and the Hollywood portrayal too fanciful to stomach.

The screen version of the intelligence world displays a perplexing interest in getting a few, small details right while otherwise throwing common sense to the wind. Why hire some ex-intelligence officer to assure that Ryan’s badge looks real and the file folders are the right colour, if the basic story has no connection with reality whatsoever? The handful of people who know what a real burn bag for classified papers looks like will also be those most critical of the show’s other failings
