Threat Awareness – Emotet Up to its Old Trick(bot) and Some New Ones Too

Since last month’s re-emergence of Emotet – Everybody’s Email Enemy #1 – we’ve observed its rekindling with Trickbot to spread and propensity for proliferating ransomware attacks. However, the last 10 months since its global takedown effort appear to have been time well-spent for the malware as it has come up with some new tricks.

Google Disrupts Large Botnet, Files Lawsuit against Russian Threat Actors

On Tuesday, Google took significant steps to disrupt and degrade the Glupteba botnet, which now controls over 1 million Windows PCs worldwide. Glupteba is a blockchain-enabled modular malware that has targeted Windows devices globally since at least 2011. Threat actors can then use the infected devices for malign purposes, such as stealing credentials or personally identifiable information.

Ransomware Awareness – New Decryption Key for STOP Ransomware Released

The cybersecurity firm G DATA just released a vaccine for the STOP ransomware variant. This decryption tool is notable given that STOP ransomware is one of the most active ransomware variants in the wild that no one talks about. In fact, of the thousands of ID Ransomware submissions received every day, during active ransomware periods, 60 to 70 percent are STOP ransomware submissions. The vaccine does not prevent an initial infection of the ransomware.

Security Awareness – Cybercrime Services and Supply Chain Fueling Cyber Attacks

New research from Trend Micro sheds light on the potential factors behind the recent surge in ransomware attacks, namely, cyber-criminal marketplaces offering initial access to threat actors. Over the past two years, demand for initial access has grown so much that many dark web markets now have a dedicated “Access-as-a-Service” section. The researchers divided access brokers into three categories: opportunistic sellers, dedicated brokers whose services are often used by smaller ransomware groups, and online shops that provide RDP and VPN credentials.

Colorado Rural Electric Cooperative Suffers Ransomware Attack

A small electric cooperative was the apparent victim of a ransomware attack that caused significant disruption and damage last month. On November 7, Delta-Montrose Electric Association (DMEA) discovered a breach on its internal enterprise network. As a result of the attack, the utility lost 90 percent of its enterprise network functions and large amounts of data, including saved documents and spreadsheets.
