The Good
With another week coming to an end, let’s take a quick glance at all the positive developments that happened this week. The Cybersecurity and Infrastructure Security Agency (CISA) came up with new strategies to strengthen the cyber ecosystem of government agencies. One of them includes the release of six Cyber Essentials toolkits that will improve the level of security awareness among organizations. The other is related to a new Domain Name System(DNS) resolver that will enhance the resiliency of online systems of federal agencies.
- As a follow-up to the November 2019 announcement of Cyber Essentials, the DHS’ CISA has released the first set of Cyber Essentials toolkits to address cybersecurity risks in government agencies and small businesses. It consists of six toolkits that are aimed at developing security awareness, protecting critical assets, and more.
- The CISA has also planned to roll out a new Domain Name System (DNS) resolver service to ensure online systems are resilient. The service will also enable CISA to gain insights into active cyber threats to analyze and protect federal agencies.
- A group of academics has developed a prototype of security and privacy labels for IoT devices to increase cybersecurity awareness among users. The labels have been created after consulting a diverse group of privacy and security experts.

New Threats
Talking about new threats, security researchers discovered a new BazarBackdoor malware operated by the gang behind the TrickBot trojan. Another new malware, dubbed USBCulprit, associated with the Cycldek APT group was also found stealing data from air-gapped systems.
- An attack campaign that distributed malicious LNK files between May 12 and May 31, is believed to be associated with the Higaisa APT group. These files were disguised as CV and International English Language Testing System (IELTS) exam results to trick users.
- Google removed two barcode reader apps - Barcode Reader and QR & Barcode Scanner - from its Play Store after they started showing unusual behavior. These apps requested ads in every 15-minutes interval, causing the screen of phones to crash.
