“The Next WannaCry” Vulnerability is Here – Let’s Stop it before it’s too Late

 
This Tuesday, Microsoft released a security patch including 48 fixes, 25 of which are defined as “critical”. While Microsoft updates happen every month, this one reveals an especially dangerous vulnerability – CVE-2017-8620. Behind this dull name hides a severe flaw affecting all current versions of Windows, which enables attackers to spread a contagious attack between computers in the network. It is not very often that such a volatile vulnerability, providing hackers with full control over entire networks, is discovered. The last time such a vulnerability was disclosed was in March 2017, when another Microsoft security patch fixed the “EternalBlue” exploit. Two months after ...

Are You Prepared for the Next Attack?

 
A WAKE-UP CALL From WannaCry and Petya to the most recent attacks today, #LeakTheAnalyst and HBO—it is now apparent that anyone or any organization is a target for cyber criminals. Attacks continue to grow at an alarming rate – in volume, sophistication and impact. As of May 2017, Check Point products are detecting over 17 million attacks each week, more than half of these attacks include payloads which are unknown at the time of detection and cannot be detected by conventional signature-based technology. These attacks serve as a wake-up call, illustrating how fragile and vulnerable organizations have become in recent years. In response to the many recent outbreaks, organizations ...

Re-Thinking the Cyber Consolidation Paradigm

 
The Battle of Consolidation vs. Best-of-Breed, does more security mean better security? You’re probably frequently scrutinizing whether or not your own organization’s cyber security is being properly managed. We’re constantly being bombarded with news of the latest cyber security attacks and hoping there are no gaps in our own organization’s security. With every new ransomware or phishing attack, the red flags start to wave. The immediate reaction is to ramp up our security and increase the number of vendors with the assumption that with these new products will keep us better protected. In reality, this unfortunately isn’t the case. In a recent survey, executives were asked ...

JavaScript Lost in the Dictionary

 
Check Point threat Intelligence sensors have picked up a stealth campaign that traditional anti-virus solutions are having a hard time detecting. On July 17th SandBlast Zero-Day Protection started showing a massive email campaign which was not caught by traditional AV solutions. Even today, on the fourth day of this campaign, when Check Point has already blocked 5,000 unique samples of the campaign, there are still only a handful of samples on VirusTotal, half of which are not detected by any AV scan engine and the others with just a handful of detections.   The campaign is related to the “BlankSlate” spam campaign which sends emails with blank body and in this case ...

Hacked in Translation – “Director’s Cut” – Full Technical Details

 
Background Recently, Check Point researchers revealed a brand new attack vector – attack by subtitles. As discussed in the previous post and in our demo, we showed how attackers can use subtitles files to take over users' machines, without being detected. The attack vector entailed a number of vulnerabilities found in prominent streaming platforms, including VLC, Kodi (XBMC), PopcornTime and strem.io. The potential damage the attacker could inflict is endless, ranging anywhere from stealing sensitive information, installing ransomware, mass Denial of Service attacks, and much more. After our original publication appeared, the vulnerabilities were fixed, which allows us to tell ...

BROKERS IN THE SHADOWS – Part 2: Analyzing Petya’s DoublePulsarV2.0 Backdoor

 
Background In the wake of WannaCry, a new cyber threat has emerged from the NSA leak. Making use of previously exposed tools, Petya once again is engaged in another large scale attack. Important distinctions in this case, however, are that the attacks targeted mainly a specific country, and are used solely for destruction. While Petya may look like ransomware, it appears that despite a victim paying the ransom, there is no way to decrypt the files afterward. Petya was first seen in 2016, as a very different attack. Compared to its first appearance, in 2017 it targeted fewer file types in order to proliferate more quickly. Another difference is that the current Petya sample, which would ...

Preventing Petya – stopping the next ransomware attack

 
Check Point’s Incident Response Team has been responding to multiple global infections caused by a new variant of the Petya malware, which first appeared in 2016 and is currently moving laterally within customer networks.  It appears to be using the ‘EternalBlue’ exploit which May’s WannaCry attack also exploited.  It was first signaled by attacks on financial institutions in the Ukraine, but soon started spreading more widely, particularly across Europe, the Americas and Asia. The ransomware is propagating fast across business networks in the same way WannaCry did last month.  However, unlike other ransomware types including WannaCry, Petya does not encrypt files on infected ...

Securing the Cloud: Ward Off Future Storms

 
A recent incident has left the voting records of 198 million Americans exposed. The data included the names, dates of birth, addresses, and phone numbers of voters from both parties. It also included voter’s positions on various political issues and their projected political preference. Although it is not unusual to collect this type of information, it should raise alarm bells that the platform hosting this data was not secured. This is the largest known data exposure in the United States, leaving the sensitive information of millions of Americans unprotected.   When it comes to protecting personal information and sensitive data, extensive measures should be taken to keep the ...

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 ...
