Check Point’s latest Global Threat Impact Index revealed more than one in four organizations globally was affected by the Fireball or Wannacry attacks during May-- in the company’s latest Global Threat Impact Index.   The top three malware families that impacted networks globally were zero-day, previously unseen attacks.  Fireball impacted one in five organizations worldwide, with second-placed RoughTed impacting 16% and third-placed WannaCry affecting nearly 8% of organizations globally.   The most prevalent malware highlight cyber-criminals are utilizing and impacting all stages of the infection chain with a wide range of attack vectors and targets.  Fireball ...

Anatomy of the Jaff Ransomware Campaign

 
Last month, Check Point researchers were able to spot the distribution of Jaff Ransomware by the Necurs Botnet. The ransomware was spread using malicious PDF files that had an embedded docm file, which in its turn downloaded an encoded executable. After the downloaded file was decoded, the ransomware encrypted the user’s files. In the last weeks, however, we were able to detect a new spam campaign delivering the ransomware and altering the chain of infection to use malicious WSF files.  New Campaign On May 28, Check Point SandBlastZero-Day Protection solution caught 8,000 messages delivering the ransomware, titled “Scanned Image from a Xerox WorkCentre," a title which was in use ...

FIREBALL – The Chinese Malware of 250 Million Computers Infected

 
Check Point Threat Intelligence and research teams recently discovered a high volume Chinese threat operation which has infected over 250 million computers worldwide. The installed malware,  Fireball, takes over target browsers and turns them into zombies. Fireball has two main functionalities:  the ability of running any code on victim computers--downloading any file or malware, and  hijacking and manipulating infected users’ web-traffic to generate ad-revenue. Currently, Fireball installs plug-ins and additional configurations to boost its advertisements, but just as easily it can turn into a prominent distributor for any additional malware. This operation is run by Rafotech, a ...

BROKERS IN THE SHADOWS: Analyzing vulnerabilities and attacks spawned by the leaked NSA hacking tools

 
Background Rarely does the release of an exploit have such a large impact across the world. With the recent leak of the NSA exploit methods, we saw the effects of powerful tools in the wrong hands. On April 14, 2017, a group known as the Shadow Brokers released a large portion of the stolen cyber weapons in a leak titled, “Lost in Translation.” This leak contained many exploits, some of which were already patched a month earlier in the Microsoft SMB critical security update (MS17-010). However, many users were unable to update their systems. Even before WannaCry hit, more than 400,000 computers in approximately 150 countries were infected with one of the tools, called DoublePulsar. ...

The Judy Malware: Possibly the largest malware campaign found on Google Play

 
Check Point researchers discovered another widespread malware campaign on Google Play, Google’s official app store. The malware, dubbed “Judy”, is an auto-clicking adware which was found on 41 apps developed by a Korean company. The malware uses infected devices to generate large amounts of fraudulent clicks on advertisements, generating revenues for the perpetrators behind it. The malicious apps reached an astonishing spread between 4.5 million and 18.5 million downloads. Some of the apps we discovered resided on Google Play for several years, but all were recently updated. It is unclear how long the malicious code existed inside the apps, hence the actual spread of the malware ...

Hacked in Translation – from Subtitles to Complete Takeover

 
Check Point researchers revealed a new attack vector which threatens millions of users worldwide – attack by subtitles. By crafting malicious subtitle files, which are then downloaded by a victim’s media player, attackers can take complete control over any type of device via vulnerabilities found in many popular streaming platforms, including VLC, Kodi (XBMC), Popcorn-Time and strem.io. We estimate there are approximately 200 million video players and streamers that currently run the vulnerable software, making this one of the most widespread, easily accessed and zero-resistance vulnerability reported in recent years.     What is it? Perpetrators use various ...

April’s Most Wanted Malware: Exploit Kit Attacks Continue, While Slammer Worm Resurfaces Again

 
Check Point’s latest Global Threat Impact Index detected a continued increase in the number of organizations being targeted with Exploit Kits, as Rig EK became the most prevalent form of attack, while there was also a resurgence in the Slammer worm detected, with 4% of businesses impacted.   Slammer resurfaced following a short hiatus, jumping back into the top three most popular malware families. The Slammer worm first emerged in 2003 and spread extremely rapidly.  It was developed to target Microsoft SQL 2000, and propagated so quickly that it was able to cause a denial of service condition on some affected targets. This is the second time the worm has entered the malware ...

Check Point Reveals Global WannaCry Ransomware Infection Map at CPX Europe 2017

 
Check Point researchers have been investigating the ransomware campaign in detail since it was first reported. With a new Check Point WannaCry Ransomware Infection Map, the researchers were able to track 34,300 attack attempts in 97 countries. The average pace as of today is one attempt in every three second – indicating a slight decline since the original pace registered two days ago, of one attempt per second. The top country from where attack attempts were registered is India, followed by the USA and Russia.   Maya Horowitz, Threat Intelligence Group Manager at Check Point said, “Although we see it slightly slowing down, WannaCry still spreads fast, targeting organizations ...

CRYING IS FUTILE: SandBlast Forensic Analysis of WannaCry

 
Using the NSA exploit EternalBlue released by the Shadow Brokers, the WannaCry ransomware developers have added their names to malware lore. Given the number of institutions hit and the amount of media generated, it seemed appropriate to show what the ransomware actually does on a system through our SandBlast Agent Forensics product. The WannaCry outbreak has been a good test case for the recently launched SandBlast Anti-Ransomware. AR and Forensics work together as part of our SandBlast Agent product. As we had expected, Anti-Ransomware was up to the task and has successfully blocked all WannaCry samples we’ve thrown at it, without requiring any signatures or updates. For this ...
