The Good

We’re back with our weekly dose of the most insightful threat intel. The past week witnessed several cybersecurity advancements, security incidents, as well as the emergence of new threats. To begin with, let’s first glance through all the good that has happened in cyberspace over the past week. Amazon is introducing a new feature dubbed ‘Alexa Guard’ which transforms the Echo smart speaker into a smart home security system. PEO STRI is setting up a “national cyber range” where US forces and their allies can conduct “in-the-box” exercises in a simulated cyber realm. Meanwhile, researchers are developing a technology inspired by fitness trackers that could prevent cyber attacks.

  • The Persistent Cyber Training Environment PEO STRI is setting up a “national cyber range” where US forces and their allies can conduct “in-the-box” exercises in a simulated cyber realm. This will provide US forces with realistic virtual training to combat cyber threats.
  • Researchers from the University of Bath and Goldsmiths and the University of London are developing a technology inspired by fitness trackers that could prevent cyber attacks. This technology would signal when someone is resetting a password or updating anti-virus software with sound, lights, and vibration.
  • Amazon is introducing a new feature dubbed ‘Alexa Guard’ which transforms the Echo smart speaker into a smart home security system. Alexa Guard feature will send alerts to users via their mobile devices if any problem is suspected at home. This feature is compatible with the Amazon Echo, Echo Dot, Echo Plus, Echo Show, Echo Spot, and Echo Input.

The Bad

Several data breaches and security incidents were witnessed over the past week. Attackers hacked the webcast of the first Eurovision semi-final to display faked explosions along with a warning about a missile attack. Magecart threat group injected its card skimming script on Forbes’ subscription website in order to steal the credit card data that customers enter on the checkout page. Last but not least, the names of the major antivirus companies that were breached by ‘Fxmsp’ hacking group have been revealed, which includes Symantec, McAfee, and Trend Micro.

New Threats

In the past week, the occurrence of several new malware strains and vulnerabilities were detected. Researchers have spotted Emotet distributing third-party payloads such as Qbot, Trickbot, IcedID, and Gootkit. Whatsapp had a critical vulnerability in its audio call feature that could allow attackers to install spyware on mobiles via a WhatsApp call. Meanwhile, researchers uncovered a flaw in Intel’s hardware that could allow attackers to extract sensitive data from a computer’s CPU.

Researchers also noted that this new version of Emotet loaded its modules for spamming, credential stealing, email harvesting, and spreading on local networks.
  • A North Korean cyber-espionage group has developed a new strain of malware that is designed to harvest information about Bluetooth devices connected to Windows systems. This malware uses Windows Bluetooth APIs to collect data from victims. The Bluetooth data that is harvested includes the name of Bluetooth-connected devices, device class, device address, and whether the device is currently connected/authenticated/remembered, or not.
  • A serious buffer overflow vulnerability was identified in the audio call feature of WhatsApp. This vulnerability could allow attackers to install spyware on mobiles via a WhatsApp call. The buffer overflow vulnerability (CVE-2019-3568) has been patched in WhatsApp versions v2.19.134 (Android), v2.19.51 (iOS), v2.18.348 (Windows Phone) and v2.18.15 (Tizen).

Attackers behind this banking malware have implemented a new technique dubbed ‘FileDelete’ to remove security software belonging to antivirus programs. This driver component ‘FileDelete’ is digitally signed with a valid certificate and is installed via the group Golang loader, leveraging PowerShell, to the local directory “C:\G DATA Security Software.
  • Google announced that its discovery of a misconfiguration flaw in the Bluetooth version of Titan Security Key that could allow nearby attackers to either communicate with the security key or with the device it’s paired with. The flaw could thereby allow attackers to ultimately hijack the Titan Security key. Google is advising users to get a free replacement device that fixes the vulnerability.
  • Researchers have uncovered security flaws in Intel’s hardware that could allow attackers to siphon sensitive data from a computer’s CPU. The series of vulnerability and exploits are classified as MDS attacks (Microarchitectural Data Sampling attacks) which include RIDL (Rogue In-flight Data Load), ZombieLoad, and Fallout.
