On March 21,2018, Morphisec Labs began investigating the compromised website of a leading Hong Kong Telecommunications company after being alerted to it by malware hunter @PhysicalDrive0. The investigation, conducted by Morphisec researchers Michael Gorelik and Assaf Kachlon, determined that the Telecom group's corporate site had indeed been hacked. Attackers added an embedded Adobe Flash file that exploits the Flash vulnerability CVE-2018-4878 on the main home.php page.

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.

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.

How an organization handles the time between the unleashing of a zero-day and the availability of a patch is telling. There are basically two kinds of companies – those that try to mitigate the risk as best they can while they wait for a patch and those that have a security tool able to prevent zero-days. The latest Flash-Player zero-day CVE-2018-4878 is yet another example.

Towards the end of 2017, a group of researchers at Embedi discovered a Microsoft Office vulnerability that’s been quietly putting systems in danger for about 17 years.

With a turbulent 2017 finally behind us, what’s the cybersecurity forecast for 2018? Some predictions need no crystal ball – the cyber labor shortage will continue, spending on security solutions will go up, the breaches that do occur will be bigger and messier. But what else is in store for 2018? Morphisec’s VP Sales Arthur Braunstein, VP Product Netta Schmeidler and our co-founder Dudu Mimram weigh in.

Two days ago, researchers at TarLogic published a proof-of-concept APT that leverages CVE-2017-11826, a Microsoft Office 0-day vulnerability existing in all Office versions. Microsoft issued a patch for the vulnerability in October, however many systems still remain at risk.

The annual holiday season has arrived. The air grows crisp (at least in the Northern hemisphere), new, cool gadgets are released and cyberattacks, along with cologne ads, proliferate. Cyber threats aren’t deterring shoppers though: The National Retail Federation expects online holiday sales to increase by 7 to 10 percent over last year, reaching as much as $117 billion. With e-commerce attacks in Q3 2016 increasing by 60 percent over the previous year, shopping hazards can hit from all sides. From phishing sites to online card skimming to compromised terminals in stores; even gifts themselves pose security risks. Still, there is much both consumers and retailers can do in order to make an all around safer shopping experience.

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.
