During the period of March to May 2019, Morphisec Labs observed a new, highly sophisticated variant of the ShellTea / PunchBuggy backdoor malware that attempted to infiltrate a number of machines within the network of a customer in the hotel-entertainment industry. It is believed that the malware was deployed as a result of several phishing attempts.

Hworm/njRAT is a Remote Access Tool (RAT) that first appeared in 2013 in targeted attacks against the international energy industry, primarily in the Middle East. It was soon commoditized and is now part of a constantly evolving family of RATs that pop-up in various new formats. Today we see this attack employed on a regular basis as part of widespread spam phishing campaigns - if successful, Hworm gives the attacker complete control of the victim’s system. Morphisec Labs recently observed a new version with a minor modification to its obfuscation technique.

Introduction

This week, Kaspersky Lab reported initial details of a new supply chain attack on systems by computer giant ASUS. Dubbed ShadowHammer by Kaspersky, the attack leveraged a malicious version of ASUS Live Update,

A new, highly sophisticated campaign that delivers the Orcus Remote Access Trojan is hitting victims in ongoing, targeted attacks. Morphisec identified the campaign after receiving notifications from its advanced prevention solution at several deployment sites.

Let’s face it – there are a lot of threat reports and threat data floating around. What makes the Morphisec Labs Threat Report different is the type of threats it analyzes. It focuses on the threats that pose a real risk to organizations, the ones that get past standard and next-generation AI antivirus.

Over the past three days, Morphisec Labs researchers have discovered a widespread cyber campaign hitting multiple targets. Morphisec researchers dubbed the campaign “Pied Piper”as it delivers various Remote Access Trojan (RAT) payloads via phishing, across multiple countries.

It seems like the rumors of FIN7’s decline have been hasty. Just a few months after the well-publicized indictment of three high-ranking members in August, Morphisec has identified a new FIN7 campaign that appears to be targeting the restaurant industry.

Over the past year, Morphisec and several other endpoint protection companies have been tracking a resurgence in activity from the Cobalt Group. Cobalt is one of the most notorious cybercrime operations, with attacks against more than 100 banks across 40 countries

After more than four years with no weaponized exploits for Adobe Acrobat Reader, researchers at ESET identified a weaponized PDF that allows attackers to execute arbitrary code on the targeted machine and eventually assume full system control. The PDF exploits two previously unknown vulnerabilities, Acrobat Reader vulnerability CVE-2018-4990 and a privilege escalation vulnerability in Microsoft Windows, CVE-2018-8120.

Adobe Reader has a built-in sandbox feature that usually makes exploitation difficult. By combining vulnerabilities, this attack achieves code execution and then bypasses the sandbox protection to fully compromise the targeted system.
