Weekly Threat Briefing • June 21, 2019

The Good

We’re back with the most interesting threat intel of the week. The past week witnessed several cybersecurity advancements, security incidents, as well as the emergence of new threats. Let’s first glance through all the positive developments that have emerged over the past week. Instagram is testing a new in-app account recovery process to help its users recover their hacked accounts. Google has announced the release of its open source multi-party computation (MPC) tool named ‘Private Join and Compute’. Meanwhile, CSIRO’s Data61 has developed a technique dubbed ‘Vaccination’ to protect artificial intelligence and machine learning algorithms from adversarial attacks.

  • Instagram is testing a new in-app account recovery process to help its users recover their accounts which have been hacked by attackers. This recovery process method would help users recover their accounts even if the hacker has changed the user name and contact details.
  • Google has announced the release of its open source multi-party computation (MPC) tool named ‘Private Join and Compute’. This tool is designed to help organizations collaborate together with confidential data sets. The tool is a cryptographic protocol that helps two parties encrypt data before sharing any confidential data for research purposes.
  • The Commonwealth Scientific and Industrial Research Organisation's (CSIRO) Data61 has announced that its researchers have developed a technique dubbed ‘Vaccination’ to protect AI and machine learning algorithms from adversarial attacks. This technique is currently used to identify spam emails, diagnose diseases from X-rays, and predict crop yields.
  • MIT researchers have presented a paper about their cryptographic system that automatically generates optimized cryptography code. This system is widely used by Google and other tech firms. The paper demonstrates how automated methods can be implemented to prevent human-made errors in generating crypto code.

The Bad

Several data breaches and security incidents were witnessed in the past week. Canada’s largest credit union Desjardins suffered a data breach compromising the personal information of almost 2.9 million customers. An unprotected database belonging to a job searching platform ‘Talanton’ has exposed the personal information of almost 1.6 million employers and job seekers.

New Threats

The past week also witnessed the occurrence of several new malware strains and vulnerabilities. A new variant of Ryuk ransomware that blacklists IP addresses to avoid encrypting already infected computers has been spotted in the wild. A critical vulnerability has been uncovered in Outlook for Android app that impacts over 100 million users. Meanwhile, a free decryptor tool for the infamous GandCrab ransomware has been released.

  • A cybersecurity firm has published the details about two zero-day vulnerabilities impacting two Facebook WordPress plugins. The two vulnerabilities are cross-site request forgery (CSRF) flaws that impact ‘Messenger Customer Chat’ and ‘Facebook for WooCommerce’ WordPress plugins. These vulnerabilities could allow authenticated users to alter WordPress site options.
  • Researchers have uncovered a new variant of the Mirai botnet dubbed Echobot. This new variant uses a total of 26 exploits to target IoT devices. Its targets include network-attached storage devices (NAS), routers, network video recorders (NVR), IP cameras, IP phones, and wireless presentation systems.
  • Researchers have observed an external script redirecting visitors to several random sites. This script is widely used by various webmasters to provide easy Lightbox functionalities on their websites. The redirected sites include pages related to viral apps or just random tech articles.
  • A security researcher has uncovered a critical remote code execution vulnerability in the TP-Link WiFi extender that could an attacker to take complete control over the device.

  • Multiple fake apps of well-known brands have been found distributing malware dubbed Android-FakeApp.174. When launched, the trojan loads a website in Google Chrome. The website asks the target to allow notifications under the guise of verifying that the user is not a bot. Once the targets have verified themselves, web push notifications are enabled in the background. This enables the spammers to spam a victim’s mobile with dozens of notifications.
  • A modular backdoor named Backdoor.Win32.Plurox has been identified spreading over a local network via an exploit. The malware is capable of installing miners and other malicious software on victims’ computers. The malware is written in C and compiled with Mingw GCC.

The security flaw is a spoofing vulnerability that could allow attackers to conduct cross-site scripting(XSS) attacks on devices installed with the app. The flaw is the result of an issue with email parsing. This vulnerability has impacted older versions prior to 3.0.88 of Outlook for Android.
  • Researchers uncovered a new JavaScript-based trojan dubbed ‘MonsterInstall’ which is distributed in the form of game cheats via websites owned by the attackers. Its capabilities include stealing system information and sending back to its C&C server, and downloading cryptomining module. It will gain persistence by adding itself to the infected system’s autorun.
  • Researchers spotted a new variant of DanaBot that comes with a new ransomware module. On top of this, the updated variant also has new plugins, configuration files, string encryptions, file name generation algorithms as well as a different communication protocol.
