-Thick Client Penetration Testing Methodology

Thick client pentesting involves both local and server-side processing and often uses proprietary protocols for communication.
Simple automated assessment scanning is not sufficient and testing thick client applications requires a lot of patience and a methodical approach. Moreover, the process often requires specialized tools and custom testing setup.

Thick client testing can be exciting for pentesters because the attack surface of these applications can be significant. Unlike web applications or infrastructure pentests, thick client pentests have a more notable success rate because the client is available locally and, hence, critical vulnerabilities may be found during the engagements

NCSC Weekly Threat Report

Ransomware attack brings down college IT

A college in Scotland fell victim to an apparent ransomware attack last week with the incident bringing down its IT systems.

Ransomware is a type of malware that makes data or systems unusable until the victim makes a ransom payment. Students of Dundee and Angus School were subsequently kept away and told that they would need to reset their passwords following the attack

Attackers using the Coronavirus as a phishing trap

The coronavirus outbreak is being used in phishing attacks according to researchers at Proofpoint.

Attackers are taking advantage of the widespread concern about the virus to lure people into phishing traps using conspiracy theories about “unreleased” cures. One example describes a ‘confidential cure solution’ before giving users the option to follow a link through to a fake website asking for credentials. Proofpoint’s report has other examples of phishing traps being utilised

Incidents & events detail

The intelligence coup of the century

A screenshot of a cell phone Description automatically generated

For decades, the CIA read the encrypted communications.

The Swiss cryptography firm Crypto AG sold equipment to governments and militaries around the world for decades after World War II. They were owned by the CIA:

But what none of its customers ever knew was that Crypto AG was secretly owned by the CIA in a highly classified partnership with West German intelligence. These spy agencies rigged the company’s devices so they could easily break the codes that countries used to send encrypted messages.

This isn’t really news. We have long known that Crypto AG was backdooring crypto equipment for the Americans. What is new is the formerly classified documents describing the details:

The decades-long arrangement, among the most closely guarded secrets of the Cold War, is laid bare in a classified, comprehensive CIA history of the operation obtained by The Washington Post and ZDF, a German public broadcaster, in a joint reporting project.

The account identifies the CIA officers who ran the program and the company executives entrusted to execute it. It traces the origin of the venture as well as the internal conflicts that nearly derailed it. It describes how the United States and its allies exploited other nations’ gullibility for years, taking their money and stealing their secrets.

The operation, known first by the code name “Thesaurus” and later “Rubicon,” ranks among the most audacious in CIA history

Escaping the Chrome Sandbox with RIDL

Vulnerabilities that leak cross process memory can be exploited to escape the Chrome sandbox. An attacker is still required to compromise the renderer prior to mounting this attack. To protect against attacks on affected CPUs make sure your microcode is up to date and disable hyper-threading (HT).

In my last guest blog post “Trashing the Flow of Data” I described how to exploit a bug in Chrome’s JavaScript engine V8 to gain code execution in the renderer. For such an exploit to be useful, you will usually need to chain it with a second vulnerability since Chrome’s sandbox will limit your access to the OS and site isolation moved cross-site renderers into separate processes to prevent you from bypassing restrictions of the web platform

Mitigations are attack surface, too

This blog post discusses a bug leading to memory corruption in Samsung’s Android kernel (specifically the kernel of the Galaxy A50, A505FN – I haven’t looked at Samsung’s kernels for other devices). I will describe the bug and how I wrote a (very unreliable) exploit for it. I will also describe how a second vulnerability, which had long been fixed in the upstream kernel, the upstream stable releases, and the Android common kernel, but not in Samsung’s kernel, aided in its exploitation

Hypervisor Necromancy

Reanimating Kernel Protectors

Until recently, to compromise an entire system during runtime attackers found and exploited kernel vulnerabilities. This allowed them to perform a variety of actions; executing malicious code in the context of the kernel, modify kernel data structures to elevate privileges, access protected data, etc. Various mitigations have been introduced to protect against such actions and hypervisors have also been utilized, apart from their traditional usage for virtualization support, towards this goal. In the Android ecosystem this has been facilitated by ARM virtualization extensions, which allowed vendors/OEMs to implement their own protection functionalities/logic

Ghost in the shell: Investigating web shell attacks

Recently, an organization in the public sector discovered that one of their internet-facing servers was misconfigured and allowed attackers to upload a web shell, which let the adversaries gain a foothold for further compromise. The organization enlisted the services of Microsoft’s Detection and Response Team (DART) to conduct a full incident response and remediate the threat before it could cause further damage.

DART’s investigation showed that the attackers uploaded a web shell in multiple folders on the web server, leading to the subsequent compromise of service accounts and domain admin accounts. This allowed the attackers to perform reconnaissance using net.exe, scan for additional target systems using nbtstat.exe, and eventually move laterally using PsExec

Attacking Driverless Cars with Projected Images

A close up of a sign Description automatically generated

The absence of deployed vehicular communication systems, which prevents the advanced driving assistance systems (ADASs) and autopilots of semi/fully autonomous cars to validate their virtual perception regarding the physical environment surrounding the car with a third party, has been exploited in various attacks suggested by researchers. Since the application of these attacks comes with a cost (exposure of the attacker’s identity), the delicate exposure vs. application balance has held, and attacks of this kind have not yet been encountered in the wild. In this paper, we investigate a new perceptual challenge that causes the ADASs and autopilots of semi/fully autonomous to consider depthless objects (phantoms) as real. We show how attackers can exploit this perceptual challenge to apply phantom attacks and change the abovementioned balance, without the need to physically approach the attack scene, by projecting a phantom via a drone equipped with a portable projector or by presenting a phantom on a hacked digital billboard that faces the Internet and is located near roads. We show that the car industry has not considered this type of attack by demonstrating the attack on today’s most advanced ADAS and autopilot technologies: Mobileye 630 PRO and the Tesla Model X, HW 2.5; our experiments show that when presented with various phantoms, a car’s ADAS or autopilot considers the phantoms as real objects, causing these systems to trigger the brakes, steer into the lane of oncoming traffic, and issue notifications about fake road signs. In order to mitigate this attack, we present a model that analyzes a detected object’s context, surface, and reflected light, which is capable of detecting phantoms with 0.99 AUC. Finally, we explain why the deployment of vehicular communication systems might reduce attackers’ opportunities to apply phantom attacks but won’t eliminate them
