2017-11-15 13:50:59 | Executive Insights: Stopping Threats Starts with Getting Back to the Basics (lien direct) | The majority of these breaches have one thing in common. IT teams are failing to practice basic security hygiene. Cybercriminals target known vulnerabilities because they know that most organizations will have failed to patch or replace their vulnerable devices. WannaCry targeted a vulnerability for which a patch had been available for months. Shame on them. But Petya followed a month later and targeted the exact same vulnerability. And millions of devices were still affected. So, shame on us. | Wannacry | ||

2017-10-27 12:50:59 | Why ICSA Advanced Threat Defense for Email is So Important (lien direct) | Verizon's 2017 Data Breach Investigations Report found that two-thirds (66%) of all installed malware that successfully made its way past established defenses were delivered by email. This is particularly concerning as our weekly FortiGuard Labs Threat Intelligence Brief lists ransomware downloaders –typically delivered via email – as consistently among the top 5 pieces of malware in most weeks. {Update chart and excerpt closer to publication date} The reality is that while brand new attacks like WannaCry and Petya... | Wannacry | ||

2017-07-30 21:00:00 | NSE Experts Academy CTF (lien direct) | At the end of this past June, Fortinet ran the NSE Experts Academy which featured for the first time a Capture The Flag (CTF) session. We welcomed close to 60 participants, and feedback was extremely positive. We congratulate the top 2 winners, with very close scores, teams YouMayNotWannaCry and ACSN. Our CTF had two specifications: While it included challenges on Fortinet products it was not limited to them - this was not a sales session but a technical one! For instance, while we had challenges on FortiSandbox, FortiCam, and FortiGate,... | Wannacry | ||

2017-07-11 12:58:00 | Outsmarting the Next Ransomware with Advanced Threat Protections (lien direct) | Ransomware has recently reasserted itself into the public eye in a big way. The May cyberattack carried out by the malware WannaCry was one of the worst ransomware attacks ever, affecting over 300,000 computers operating MS Windows around the world. Unfortunately, the attack has once again demonstrated that far too many organizations do not have an effective security protocol in place, or do not take it seriously until after disaster strikes. In this case, the Microsoft vulnerability exploited by WannaCry had been patched in March, but many users... | Wannacry | ||

2017-07-06 20:00:00 | WannaCry and Petya: The Circus Comes to Town (lien direct) | By now, you will have all heard about the rampant spread of ransomware through countless press pieces, blog articles, and far too often, the outrageous claims of some security vendors. But let's stop and think for a minute or two. How did these attacks happen? Are companies focusing on valid threats, fixing the right problems, or developing correct processes? Have so-called disruptive technologies disrupted our thinking? Let's not go tactical. Instead, we need to consider, “what is our best strategy?†Ever since the... | Wannacry | ||

2017-07-03 12:58:00 | Byline: Petya, Wannacry, and Mirai - Is This the New Normal? (lien direct) | This past year, cybercriminals have upped the stakes once again with the high profile, global attacks of Mirai, Wannacry, and Petya, launched one after the other. Of course, large-scale attacks aren't new. Attacks like the ILOVEYOU worm and Code Red and Nimda were massive attacks, some of which affected exponentially more devices and organizations that this latest round of attacks. The spread of WannaCry and Petya were quickly curbed unlike these worms of the past. But this isn't just about scale. Unlike in years past, the new digital... | Wannacry | ||

2017-06-28 18:05:00 | A Technical Analysis of the Petya Ransomworm (lien direct) | Yesterday, a new ransomware wreaked havoc across the world. This new malware variant, which combines the functionality of ransomware with the behaviors of a worm, is being called Petya, Petrwrap, and even NotPetya, since researchers are still investigating as to whether its ability to modify the Master Boot Record of a targeted machine is based on the Petya family of malware. Fortinet has designated this new hybrid form of malware as a ransomworm, and this outbreak was reported to use the same worm mechanism to spread across the Internet as WannaCry,... | NotPetya Wannacry | ||

2017-06-27 17:00:00 | New Ransomworm Follows WannaCry Exploits (lien direct) | We are currently tracking a new ransomware variant sweeping across the globe known as Petya. It is currently having an impact on a wide range of industries and organizations, including critical infrastructure such as energy, banking, and transportation systems. This is a new generation of ransomware designed to take advantage of timely exploits. This current version is targeting the same vulnerabilities that we exploited during the recent Wannacry attack this past May. This latest attack, known as Petya, is something we are referring to as... | Wannacry | ||

2017-06-14 13:02:02 | Evolving towards a Homogenous Society: The Risk of the New Digital Economy (lien direct) | The recent WannaCry attack was interesting for a couple of reasons. First, the speed and scale of the attack was impressive. Over the course of a couple of days, hundreds of thousands of systems were affected and disrupted. Second, it also unveiled a disturbing trend. The attack malware exploited a known vulnerability that not only had been revealed through the highly public release of stolen cyber tools, but Microsoft had also released a patch for the targeted vulnerability over two months before. Which means that the scale of the attack was... | Wannacry | ||

2017-05-31 08:48:31 | Byline: WannaCry is Part of a Bigger Problem (lien direct) | The most important question related to the recent WannaCry attacks isn't who the attackers were, or how big the attack was. The question is, “How did this happen in the first place?†The vulnerability exploited by this attack had been patched by Microsoft months before. That patch was part of a widely publicized update that was issued in response to the massive set of NSA cyberespionage tools leaked by the secretive group known as Shadow Brokers. Everyone knew about it. Yet, apparently, few did anything about it. Failure... | Wannacry | ||

2017-05-23 15:37:42 | Automating Security Operations: What It Takes to Defend Against Something Like WannaCry (lien direct) | A major challenge facing security vendors today is that most solutions and products are developed based on knowledge of previous threats that already exist. This makes many security solutions reactive by their very design, which is not a tenable strategy for facing the volume of new attacks and strategies arising today. This arms race of identifying new threats, then reacting has been the primary strategy since the dawn of malware: A new virus is identified and then security vendors write the antivirus signature to block it; a polymorphic virus... | Wannacry | ||

2017-05-18 15:01:24 | Perspective: The Aftermath of the WannaCry Attack (lien direct) | A perspective blog with Derek Manky, Global Security Strategist, Fortinet. We asked Derek to put WannaCry into context. Is this just the eye of the storm? | Wannacry | ||

2017-05-17 19:15:57 | WannaCry FAQ - Take-aways and Learnings (lien direct) | WannaCry FAQ: How does WannaCry spread? WannaCry has multiple ways of spreading. Its primary method is to use the Backdoor.Double.Pulsar backdoor exploit tool released last March by the hacker group known as Shadow Brokers, and managed to infect thousands of Microsoft Windows computers in only a few weeks. Because DoublePulsar runs in kernel mode, it grants hackers a high level of control over the compromised computer system. | Wannacry | ||

2017-05-15 19:22:50 | Critical Update: WannaCry Ransomware (lien direct) | On May 12th, 2017 the ransomware WannaCry disrupted hundreds of organizations in dozens of countries. The ransomware encrypts personal and critical documents and files and demands approximately $300 USD in BitCoin currency for the victim to unlock their files. | Wannacry | ||

2017-05-15 15:33:01 | No Tears for WannaCry: Five Steps Every CISO Should Consider for Protecting Your Organization from Ransomware (lien direct) | Â Over the past few days WannaCry malicious malware variants affect hundreds of organizations across the world. This cyberattack spread primarily by exploiting a vulnerability whose manufacturer had issued a critical security update for over two months ago. While there are certainly reasons why it may take an organization some time to patch vulnerable systems, including the risk of updating live systems, two months should be plenty of time for any organization to take appropriate steps to secure their environment. With the recent malware... | Wannacry | ||

2017-05-15 11:31:45 | WannaCry: Evolving History from Beta to 2.0 (lien direct) | The WannaCry malware was responsible for a massive infection beginning that affected organizations and systems around the world. FortiGuard Labs has been monitoring this malware carefully. We have provided an analysis of this attack, along with how to protect your organization here. Â In this blog post I'll briefly describe some of the distinct characteristics of each version of this malware, from beta to the latest 2.0 version, and share some interesting findings. Beta Version: We discovered this beta version around Feb 9th,... | Wannacry |
