Ransomware: contemporary threats, how to prevent them and how the FBI can help In April 2021, Dutch supermarkets faced a food shortage. The cause wasn't a drought or a sudden surge in the demand for avocados. Rather, the reason was a ransomware attack. In the past years, companies, universities, schools, medical facilities and other organizations have been targeted by ransomware threat actors, turning ransomware into the internet's most severe security crisis. The Ransomware Landscape Ransomware has existed for more than 30 years, but it became a lucrative source of income for cyber actors and gangs in the past decade. Since 2015, ransomware gangs have been targeting organizations instead of individuals. Consequently, ransom sums have increased significantly, reaching millions of dollars. Ransomware is effective because it pressures victims in two, complementary ways. First, by threatening victims to destroy their data. Second, by threatening to publicize the attack. The s...

Remember NotPetya ? The Ransomware that shut down thousands of businesses, organisations and banks in Ukraine as well as different parts of Europe in June this year. Now, Ukrainian government authorities are once again warning its citizens to brace themselves for next wave of "large-scale" NotPetya-like cyber attack. According to a press release published Thursday by the Secret Service of Ukraine (SBU), the next major cyber attack could take place between October 13 and 17 when Ukraine celebrates Defender of Ukraine Day (in Ukrainian: День захисника України, Den' zakhysnyka Ukrayiny). Authorities warn the cyber attack can once again be conducted through a malicious software update against state government institutions and private companies. The attackers of the NotPetya ransomware also used the same tactic—compromising the update mechanism for Ukrainian financial software provider called MeDoc and swapping in a dodgy update including the NotPetya computer v...

Here are three of the worst breaches, attacker tactics and techniques of 2022, and the security controls that can provide effective, enterprise security protection for them. #1: 2 RaaS Attacks in 13 Months Ransomware as a service is a type of attack in which the ransomware software and infrastructure are leased out to the attackers. These ransomware services can be purchased on the dark web from other threat actors and ransomware gangs. Common purchasing plans include buying the entire tool, using the existing infrastructure while paying per infection, or letting other attackers perform the service while sharing revenue with them. In this attack, the threat actor consists of one of the most prevalent ransomware groups, specializing in access via third parties, while the targeted company is a medium-sized retailer with dozens of sites in the United States. The threat actors used ransomware as a service to breach the victim's network. They were able to exploit third-party creden...

By now I am sure you have already heard something about the WannaCry ransomware , and are wondering what's going on, who is doing this, and whether your computer is secure from this insanely fast-spreading threat that has already hacked nearly 200,000 Windows PCs over the weekend. The only positive thing about this attack is that — you are here — as after reading this easy-to-understandable awareness article, you would be so cautious that you can save yourself from WannaCry, as well as other similar cyber attacks in the future. Also Read — Google Researcher Finds Link Between WannaCry Attacks and North Korea . Since this widely spread ransomware attack is neither the first nor the last one to hit users worldwide, prevention is always the key to protect against such malware threats. What is WannaCry? How to Protect your Computer from WannaCry Ransomware? Follow These Simple Steps. TWEET THIS In this article, we have provided some of the most important primary secu...

China has something very impressive that we are not aware of. The country has a powerful and previously unknown weapon that its government is using to bolster their cyber attack capabilities: Dubbed " The Great Cannon. " INTERNET CENSORSHIP IN CHINA When I talk about Internet censorship, it is incomplete if I don't mention China. China is famous for its Great Wall of China and Great Firewall of China . The censoring of Internet access and blocking an individual website in China by its government, known as the Great Firewall of China. But, why the Chinese government does that? The answer is very simple: The Chinese government restricts those contents it deems sensitive for its country's so-called democracy. It illegalize certain online speech and activities, block selected websites, and filter keywords out of searches initiated from computers located in Mainland China. The worse: Those Chinese citizens who offend authorities against Int...

Medieval castles stood as impregnable fortresses for centuries, thanks to their meticulous design. Fast forward to the digital age, and this medieval wisdom still echoes in cybersecurity. Like castles with strategic layouts to withstand attacks, the Defense-in-Depth strategy is the modern counterpart — a multi-layered approach with strategic redundancy and a blend of passive and active security controls.  However, the evolving cyber threat landscape can challenge even the most fortified defenses. Despite the widespread adoption of the Defense-in-Depth strategy, cyber threats persist. Fortunately, the Defense-in-Depth strategy can be augmented using Breach and Attack Simulation (BAS), an automated tool that assesses and improves every security control in each layer. Defense-in-Depth: False Sense of Security with Layers Also known as multi-layered defense, the defense-in-depth strategy has been widely adopted by organizations since the early 2000s. It's based on the assumption th...

Incident response (IR) is a race against time. You engage your internal or external team because there's enough evidence that something bad is happening, but you're still blind to the scope, the impact, and the root cause. The common set of IR tools and practices provides IR teams with the ability to discover malicious files and outbound network connections. However, the identity aspect - namely the pinpointing of compromised user accounts that were used to spread in your network - unfortunately remains unattended. This task proves to be the most time-consuming for IR teams and has become a challenging uphill battle that enables attackers to earn precious time in which they can still inflict damage.  In this article, we analyze the root cause of the identity of IR blind spots and provide sample IR scenarios in which it acts as an inhibitor to a rapid and efficient process. We then introduce Silverfort's Unified Identity Protection Platform and show how its real-time MFA and ident...

Security researchers have revealed a new attack to steal passwords, encryption keys and other sensitive information stored on most modern computers, even those with full disk encryption. The attack is a new variation of a traditional Cold Boot Attack , which is around since 2008 and lets attackers steal information that briefly remains in the memory (RAM) after the computer is shut down. However, to make the cold boot attacks less effective, most modern computers come bundled with a safeguard, created by the Trusted Computing Group (TCG), that overwrites the contents of the RAM when the power on the device is restored, preventing the data from being read. Now, researchers from Finnish cyber-security firm F-Secure figured out a new way to disable this overwrite security measure by physically manipulating the computer's firmware, potentially allowing attackers to recover sensitive data stored on the computer after a cold reboot in a matter of few minutes. "Cold boot...

Not every risk looks like an attack. Some problems start as small glitches, strange logs, or quiet delays that don't seem urgent—until they are. What if your environment is already being tested, just not in ways you expected? Some of the most dangerous moves are hidden in plain sight. It's worth asking: what patterns are we missing, and what signals are we ignoring because they don't match old playbooks? This week's reports bring those quiet signals into focus—from attacks that bypassed MFA using trusted tools, to supply chain compromises hiding behind everyday interfaces. Here's what stood out across the cybersecurity landscape: ⚡ Threat of the Week Cloudflare Blocks Massive 7.3 Tbps DDoS Attack — Cloudflare said it autonomously blocked the largest distributed denial-of-service (DDoS) attack ever recorded, which hit a peak of 7.3 terabits per second (Tbps). The attack, the company said, targeted an unnamed hosting provider and delivered 37.4 terabytes in 45 seconds. It origi...
