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.

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.

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.

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.

Guloader is a downloader that has been widely used from December 2019. Several security researchers have identified the downloader in the wild, signifying that it has quickly gained popularity among threat actors. When it first appeared, GuLoader was used to download Parallax RAT, but has been applied to other remote access trojans and info-stealers such as Netwire, FormBook, and Tesla.

Following the increase in Parallax RAT campaigns -- the new RAT on the block, Morphisec Labs decided to release more technical details on some of the latest campaigns that the Morphisec Unified Threat Prevention Platform intercepted and prevented on our customer’s sites.

The Trickbot trojan is one of the most advanced malware delivery vehicles currently in use. Attackers have leveraged it to deliver a wide variety of malicious code, in many different methods. Just yesterday, Bleeping Computer reported that news articles from President Trump’s impeachment trial have been used to hide Trickbot from antivirus scanners.

A whopping 186.4 million Americans shopped in stores and online between Black Friday and Cyber Monday this year, according to the National Retail Federation. On average, these shoppers spent $361.90 per person over the five-day Thanksgiving weekend.

Last week, a new strain of ransomware hit dozens of targets across Germany. The categorization as ransomware is really a misnomer as, while the attackers do demand a ransom, by that time the victim’s data has already been irreversibly wiped, even if the ransom is paid.
