Morphisec Labs has been tracking FIN7 (Carbanak Group) activity for the past several years. Morphisec’s ability to collect rich forensic data from memory has provided unique visibility into multiple FIN7 campaigns that our researchers were proud to share with MITRE and the InfoSec community at large. Fin7 is a well-funded financially motivated cybercrime group. Their advanced techniques and tactics were even emulated in the third round of the MITRE ATT&CK evaluations.

An Infostealer is a trojan that is designed to gather and exfiltrate private and sensitive information from a target system. There is a large variety of info stealers active in the wild, some are independent and some act as a modular part of a larger task such as a Banking Trojan (Trickbot) or a RAT.

Introduction

The Agent Tesla information stealer has been around since 2014. During the last two to three years, it's also had a significant distribution growth factor partially due to the fact that cracked versions of it have been leaked.

The Morphisec Labs team has prevented on our customers’ sites a massive Trickbot and Emotet phishing campaign during the 10th and 11th of September. Trickbot is one of the most advanced malware frameworks active today; it constantly evolves with more innovative methods to achieve its goals.

Morphisec Labs has tracked a massive maldoc campaign delivering the QakBot/QBot banking trojan, starting earlier this month. Qakbot leverages advanced techniques to evade detection and hamper manual analysis of the threat. In this post we will mention two of those interesting techniques.

Garmin has confirmed that the recent outage its users experienced was indeed the result of a successful ransomware attack. However, the extent of the damage done is still unclear. The attack, which compromised Garmin’s servers for five days, impacted millions of users globally and will likely end up costing Garmin millions of dollars in lost productivity and reputation alone. While Garmin says that no customer data was leaked, Garmin's call centers, web site, and cloud-based services such as Garmin Connect and FlyGarmin (a commercial aviation navigation service) were either taken offline or negatively impacted as a result of the attack.

Since early March, the team at Morphisec Labs has been supporting enterprises as they shift to distributed workforces in response to COVID-19. From assisting hospitals with securing their remote workers to uncovering new weaknesses in collaboration applications that could pose a threat to business continuity, we’ve been working hand-in-hand with customers, counterparts at security companies, and authorities to stay ahead of defending against a rapidly evolving cyberattack landscape.

The Morphisec Labs team has tracked an obfuscated VBScript package in campaigns since March 2020. Initially, the malware campaign was focused on targets within Germany, but has since moved on to additional targets--excluding any IP address within Russia or North Korea.

As part of a rapid change in the work environment during the COVID-19 pandemic, Morphisec Labs has been tracking the change in the attack trend landscape. This has included the evolution of adware, PUA, and fraudulent software bundle delivery beyond a consumer problem into a significant attack vector on enterprise employees.

Ursnif/Gozi Introduction:

Morphisec has been tracking an uptick in the delivery of Ursnif/Gozi during the COVID-19 pandemic. Specifically, we have noticed a significant spike both in numbers and sophistication. The latest delivery methods will many times involve old-school Excel 4.0 macro functionality, which historically is a blind spot for AV detection as it has nothing to do with the VBA macro engine and is integrated as part of the workbook. INQUEST reported the use of similar techniques as part of a Zloader delivery campaign. Interestingly, in the latest campaign, it looks like the malware writers removed the image from the Excel document to avoid OCR heuristic detection following the INQUEST article.
