2021-09-12 00:00:00 | Règlements et ransomwares: un aperçu rapide de la vue d'ensemble de ce que les entreprises doivent savoir sur les ransomwares et les réglementations connexes. Regulations & Ransomware: A Quick OverviewAn overview of what enterprises need to know about ransomware and related regulations.Read More (lien direct) |
As cybersecurity threats continue to evolve, ransomware has recently come into focus as one of the more prominent and challenging types of attacks to deal with. Not only do companies need to face the security implications of having their data fall into the hands of cybercriminals, but there can be significant costs around paying ransoms and/or recovering systems and files. Plus, paying ransoms can raise some ethical if not legal issues. There are already several existing regulations that enterprises need to keep in mind if hit with a ransomware attack. And as the risk grows, a number of new regulations are under consideration around the world.In this brief overview, weâll explore what enterprises need to know about ransomware and related regulations.What Is Ransomware?Before diving into what to do about ransomware and what regulations to follow, itâs important to understand what ransomware is.âRansomware is a form of malware designed to encrypt files on a device, rendering any files and the systems that rely on them unusable. Malicious actors then demand ransom in exchange for decryption,â explains the U.S. Cybersecurity & Infrastructure Security Agency (CISA).In other words, ransomware can lock a user out of their own files/systems, which can bring work to a halt. Even if the ransom is paid and everything gets unlocked, itâs possible that the cybercriminals stole data meanwhile. While some of the more headline-grabbing attacks have been at large, well-known companies, ransomware can essentially affect anyone, regardless of size, industry or location.How to Reduce the Risk of RansomwareAlthough ransomware is on the rise, there are still several steps organizations can take to reduce the risk of a ransomware attack or at least mitigate the damage.âAs with all risks posed by external actors, the likelihood that a ransomware attack is successful can be drastically reduced by tightening the security of the data controlling environment,â notes the European Data Protection Board (EDPB).From updating software and systems with appropriate security patches, to using anti-malware software or related monitoring services, there are many cybersecurity best practices that can potentially keep ransomware out, as the EDPB highlights.If ransomware does take hold, having complete backups can help. As the EDPB notes, the impact of ransomware âcould effectively be contained,â by resetting systems to wipe out the ransomware and then âfixing the vulnerabilities and restoring the affected data soon after the attack.âOrganizations can also get a better handle on ransomware risk via cyber risk quantification (CRQ), such as through Kovrrâs insurance-validated risk models. CRQ works by analyzing factors such as past cyber events and the technologies and service providers that a company uses to then quantify what companies might lose if a cyber attack like ransomware occurs. Part of being prepared means knowing how much is at stake financially, and CRQ can help organizations focus on the areas that present the largest financial risk. âWhat Ransomware Regulations Exist?Current ransomware regulations differ around the world, so the specific rules an enterprise needs to follow depends on factors like what markets they operate in and whether they fall under certain jurisdictions.Communicating AttacksOne of the more notable rules that relates to ransomware is the EUâs General Data Protection Regulation (GDPR), which can still apply to companies outside Europe, such as those that have customers in the EU. Under GDPR, explains the EDPB, a personal data breach needs to be reported to relevant authorities and potentially to the people whose data gets exposed. So, for example, if a ransomware incident involves a cybercriminal locking up files that contain personal information, such as financial or medical records, then the affected company may need to report that to those affected.In the U.S. the | Ransomware Data Breach Malware Vulnerability Prediction Medical | ★★★ | |

2021-04-22 00:00:00 | Travailler à domicile: une année en revue les entreprises sont obligées de permettre à leurs employés de travailler à distance, la surface d'attaque devient plus large. Working From Home: A Year in ReviewAs companies are obliged to allow their employees to work remotely, the attack surface becomes broader.Read More (lien direct) |
Cyber Trends, Risks and the Global PandemicAs we mark a year of working from home through the global pandemic, this is a good time to discuss and delve into the IT changes and trends in our day-to-day work environment and their implications for user privacy, corporate cyber security and cyber insurance. The 3 main categories of software and applications that saw a significant increase in usage over the past year include:Video Conferencing and online communication platformsVPNs and Remote Desktop (RDP) softwaresTwo Factor (2FA) and Multiple Factor Authentication (MFA) applicationsWorking from home has increased the usage of the aforementioned technologies as well as other similar applications, broadened the attack surface and provided new opportunities for various malicious actors as there are more external-internal connections compared to the past, meaning more types of services to keep track of and monitor. This also implies a heavier traffic load due to video streaming, database connections and more. âEasier communication, but at what cost?Away from our colleagues and offices, employees have had to adapt quickly to various methods of online communication and meetings in order to keep things running, whether itâs Zoom, Webex, Microsoft Teams, Google meet or any other platform, co-workers are now able to chat, share video and documents easily from computers and phones. Right from the start of the pandemic, Zoom solidified itself as the dominant platform for video conferencing with an increase of 67% in usage between January and the middle of March 2020. By April 2020 it already had more than 300 million daily Zoom meeting participants in comparison to 10 million meeting participants in December 2019.(1)Number of daily Zoom users, December 2019 - April 2020This convenience comes with significant underlying risks to users and corporate networks, as poorly implemented encryption protocols and other security measures can result in unauthorized participants access to otherwise personal or confidential calls. This sort of intrusion, commonly referred to as âZoom Bombingâ, can be at best innocent trolling and cause annoyance but at worst allow access to a malicious actor who can gather sensitive information on the company for espionage purposes(2), harvest participants\' credentials and other PII and leak the callâs content and video as well as use the meeting chat to send phishing links which could escalate to a full-blown ransomware attack on the company\'s network(3). This sort of attack can be carried out by an attacker exploiting vulnerabilities such as (or similar to) CVE-2019-13450(4) which would allow them to forcefully join a meeting. âMultiple Factor Authentication - double the safety but not without risks Multiple Factor Authentication (MFA) and Two Factor Authentication (2FA) have been adopted in recent years as an additional security tool to ensure the safety of oneâs accounts and personal information. As previously mentioned, the migration to a remote work routine necessitated a secure and verified method for each employee to access their companyâs assets online on a daily basis. This basic work necessity came with restrictions and guidelines such as remote desktop applications to create a virtual work environment and 2FA applications in an attempt to strengthen the companyâs cybersecurity posture. By May 2020, around 70% of British businesses were already using some type of MFA and a VPN for better cyber security risk management of the changed work environment(5).There are numerous ways by which MFA or 2FA methods can be bypassed, either through brute force (if the requested code is between 4-6 numbers), social engineering or a conventional session management in which attackers use the password reset function. This is due to the fact that 2FA is often not implemented on the systemâs login page after a password reset.VPNs and RDPs - work from anywhere and be attacked from anywhereVi | Ransomware Data Breach Malware Tool Vulnerability | ★★★ | |

Modeling a Cyber CatastropheâCounting the Cost of a Major Email Service Provider Outage in the UKExecutive SummaryThe cyber books of many (re)insurers may be modest; however, their potential exposure to a cyber catastrophe could be very large. Even though overall cyber premiums are significantly lower than property in the UK, this report demonstrates that the potential for a multi-billion dollar insured loss is similar to the risk of floods catastrophes covered by property insurance.IntroductionEvery day 290 billion email messages are sent worldwide by 3.9billion users, facilitating a $15 trillion global economy comprised of over 150 million organizations. Email is an integral critical business service for organizations operating in the digital age. Businesses use email to communicate internally with staff and externally with their customers, clients, partners, and supply chain. Behind these huge numbers are a small number of email service providers (such as Microsoft, Google, and Rackspace) that account for the majority of all emails sent. This presents a potentially disastrous risk to the availability of this essential service if one was to suffer an outage as the result of a cyber-attack.A cyber-attack on an email service provider lasting hours, days or weeks and the resulting outage would lead to a substantial financial impact on a (re)insurance carrier. The key characteristics of this type of cyber catastrophe are high severity and low frequency, meaning, an event that does not occur regularly but entails great damage potential, effecting numerous businesses and leading to multiple claims on a (re) insurance carrier at a single point in time.âThe financial damage caused by a cyber catastrophe, such as an email outage, could also manifest through silent risk. Regulators are increasing requirements to quantify this potential silent cyber risk. In January 2019 the PRA(Prudential Regulation Authority) that regulates the UK Financial Services market (inc. the insurance market) demanded that UK insurance firms should seek risk models and expertise to estimate the potential silent (non-affirmative) cyber exposure across their portfolios and introduce robust mitigation strategies for limiting any potential risks.âThis report examines an attack on an email service provider in the UK leading to a service outage resulting from a single point of failure, an event that can lead to financial damage and claims due to affirmative cyber coverage. In this report the authors utilized Kovrrâs ability to quantify potential exposure to cyber catastrophes based on the composition of specific portfolios. Kovrrâs predictive modeling platform was used to map the underlying technologies and services used by the insured companies, enabling an understanding of the potential accumulation risks that are derived from the aggregation of their network of utilized technologies and service providers.âData Wipe Case Study: VFEmail.netOn the 11th February, 2019, hackers breached the servers of the email provider VFEmail.net and deleted all the data from its US servers, destroying all US customers data in the process. Users withVFEmail accounts were faced with empty inboxes and left with no recovery backup options. This was not the first occasion that VFEmail had been targeted. In 2015, VFEmail suffered a DDoS (DistributedDenial of Service) attack after the owner declined to pay a ransom demand from an online extortion group. The company was also forced to find a new hosting provider after a series of DDoS attacks in 2017.âAnatomy Of An AttackAn attack on an email service provider, larger thanVFEmail, could result in critical data being held hostage, altered or destroyed for multiple organizations. This analysis reflects the financial loss resulting from this large-scale business interruption event and the insured loss due to insurance claims that would be triggered in the event of an email service provider outage.
