Several weeks ago, my good friend Katie Nickels (Director of Intelligence at Red Canary extraordinaire) and I were chatting about Ransomware. She was super interested and passionate about some new uses of a ransomware variant named “Ryuk” (first detected in 2018 and named after a manga/anime character) [1]. I was, to be honest, much less interested. It turns out, as usual, Katie was right; this was a big deal (although as you will see, I’m right too… still dull stuff!).

Cybersecurity Infrastructure Security Agency (CISA) released Alert (AA20-302A) on October 28th called “Ransomware Activity Targeting the Healthcare and Public Health Sector.” This alert details TTPs associated with ongoing and possible imminent attacks against the Healthcare sector, and is a joint advisory in coordination with other U.S. Government agencies.

The Cybersecurity and Infrastructure Agency (CISA) of the U.S. Department of Homeland Security recently announced that activity in LokiBot, a form of aggressive malware, has increased dramatically over the last two months. The activity increase was discovered by an automated intrusion detection system referred to as EINSTEIN, which the Department of Homeland Security uses for collecting and analyzing security information across numerous government agencies.

First identified as active in November 2012, 'njRAT', also known as 'Bladabindi' or 'Njw0rm', is a well established and prevalent remote access trojan (RAT) threat that was initially created by a cybercriminal threat group known as 'Sparclyheason' and used to target victims located in the Middle East. Undoubtedly following the source code leak, reportedly in May 2013, njRAT has become widely available on the cybercriminal underground with numerous variants being released over the years.

Kovter is a fileless malware that attempts to remain invisible and targets the Windows operating system. Kovter avoids detection as it relies on the host registry to store its configuration data, thus avoids traditional endpoint protection (anti-virus) file scanning.

Historically targeting the financial sector, and first observed in 2014 as a banking trojan, Emotet remains an active and credible threat to organizations across all industries worldwide and, whilst retaining some core data stealing capabilities, has evolved to act as a downloader for secondary malicious payloads.

Since stepping into the cybercriminal arena in September 2020, the Egregor group has penetrated over 71 businesses globally, including recruitment giant Randstad and US retailer Kmart. But who is the Egregor group and how have they managed to rise up as a significant cyber threat in just a few short months? Egregor is a cybercriminal group specializing in a unique branch of ransomware attacks.

Since ransomware was founded in 1996, many ransomware gangs have attempted and failed to quake the cybersecurity landscape. But some have broken through and even rearranged it with their obfuscatory cyberattack methods. Netwalker ransomware is an example of such a success. Within its first six months of operation, the ransomware gang received more than $25 million in ransom payments. What is Netwalker ransomware and why is it so lethal? To learn more, read on.

Cybersecurity is in the news again with the disclosure that Tesla, working in conjunction with the FBI, prevented a ransomware attack from being launched at its Gigafactory in Nevada. The cybercriminals targeted Tesla through one of its employees, whom they allegedly promised to pay $1 million in order to help them infect the company’s system with malware.

Emotet originally arrived on the scene as a new banking trojan in 2014. In the past 12 months, however, it has evolved from a standalone threat into a prolific distributor of other trojans, including TrickBot, Zeus Panda Banker, IcedID, Qakbot, and Dridex.
