These days, most malware employs a long attack chain with anti-analysis techniques to make it more difficult to detect the payload and harder to analyze by security researchers. More and more frequently, they are also incorporating coin miners in attacks. Such is the case with a newly observed variant of the Dofoil (also known as Smoke Loader) trojan, which includes a resource-draining cryptocurrency-mining payload. This latest Dofoil strain entered the scene earlier this month and is currently still active.

On February 22, 2018, Morphisec Labs spotted several malicious word documents exploiting the latest Flash vulnerability CVE-2018-4878 in the wild in a massive malspam campaign. Adobe released a patch early February, but it will take some companies weeks, months or even years to rollout the patch and cyber criminals keep developing new ways to exploit the vulnerability in this window

GandCrab Ransomware

These days, most malware employs long chain attack and anti-analysis techniques to make it more difficult to detect the payload and harder to analyze by security researchers. Such is the case with GandCrab, a new ransomware strain that entered the scene late last month and is currently active.

Before diving into the analysis of CVE-2018-4878, a quick reminder that this is the continuation of our previous post, which provided background on CVE-2018-4878, including a  video of how Morphisec prevents any attacks leveraging this Flash vulnerability. Morphisec prevents the attack at all phases and components in the attack chain – during the exploit, the shellcode, as well as the malware which is executed using wbscript.exe with additional in-memory command control code.

At the time of the previous post, the vulnerability was still a zero-day. Adobe released a new version that fixed the flaw yesterday. With that fix available, Morphisec is now free to release technical details of the attack.

A report co-authored by Michael Gorelik, CTO and VP R&D, and Roy Moshailov, Malware Research Expert at Morphisec.

Fileless malware is a type of a malicious code execution technique that operates completely within process memory; no files are dropped onto the disk. Without any artifacts on the hard drive to detect, these attacks easily evade current detection solutions.

This report was authored by: Michael Gorelik and Assaf Kachlon.

Last week’s malware news was filled with the CCleaner backdoor exposed by Morphisec’s security solution. This week Morphisec uncovered another ongoing malware campaign, this one a drive-by-download attack that uses a modified version of the old (in hacker time) favorite, the RIG exploit kit.

First appearing in 2014, RIG generally uses gates to redirect victims from a compromised website to a landing page that contains the EK, exploiting vulnerabilities in JavaScript, Flash and VBscript in the infection chain.

Over the past 10 days, Morphisec's Threat Prevention Solution stopped a modified RIG exploit kit distributed to a large number of customers in a major drive by download campaign. Upon customer notification about the web-borne attack, we immediately identified the type of exploit kit and the delivered exploits. We reported the abuse of the registered domains to Freenom.com, the domain registration entity.

As widely reported today, the Avast-owned security application CCleaner was illegally modified by hackers to establish a backdoor to the hackers’ server. According to Avast, some 2.27 million users were running the weaponized version 5.33 of CCleaner. In addition, the CCleaner cloud version 1.07 was affected. Morphisec was first to uncover the CCleaner Backdoor and notify Avast. 

Morphisec identified and prevented malicious CCleaner.exe installations on August 20 and 21, 2017 at customer sites. On September 11, 2017, some customers shared their logs of the prevented attacks with Morphisec, which our team immediately started to investigate.

INTRODUCTION

On June 7, 2017, Morphisec Lab identified a new, highly sophisticated fileless attack targeting restaurants across the US. The ongoing campaign allows hackers to seize system control and install a backdoor to steal financial information at will. It incorporates some never before seen evasive techniques that allow it to bypass most security solutions – signature and behavior based.
