IntroductionIn this report, Kovrr collected and analyzed data to better understand one of the most common initial access vectors (1) - the use of compromised credentials (Valid Accounts - T1078) (2) to access internet-exposed assets (External Remote Services - T113) (3). The toxic combination of these two initial access vectors can allow malicious actors to gain a foothold in company networks before moving on to the next stage of their attack, which can be data theft, ransomware, denial of service, or any other action. There are numerous examples of breaches perpetrated by many attack groups that have occurred using this combination, for example, breaches by Lapsus (4) and APT39 (5), among others. âThis report seeks to demonstrate which industries and company sizes have the highest percentage of compromised credentials and number of internet-exposed assets and face a higher risk of having their networks breached by the toxic combination of the initial access vectors mentioned above.âIt should be noted that having an asset exposed to the internet does not inherently pose a risk or indicate that a company has poor security. In our highly digitized world, companies are required to expose services to the internet so their services can be accessed by customers, vendors, and remote employees. These services include VPN servers, SaaS applications developed by the company, databases, and shared storage units. However, there are some common cases when having an asset exposed to the internet can be extremely risky, for example:âWhen a company unintentionally exposes an asset due to misconfiguration.When a malicious third party obtains compromised credentials of a legitimate third party and accesses an exposed asset.  âTo limit unnecessary internet exposure, companies should employ the following possible mitigations:âUse Multi-Factor Authentication (MFA) for any services or assets that require a connection so that compromised credentials on their own will not be enough to breach an exposed asset.Limit access to the asset to only specific accounts, domains, and/or IP ranges.Segment the internal company network and isolate critical areas so that even if a network is breached through access to an external asset, attackers will not be able to use that access to reach wider or more sensitive areas of the company network. âSummaryâThe following are the main findings from the collected data:âThe Services industry is by far the most exposed to attackers. Companies from that industry have the highest percentage of compromised credentials (74%). However, they have a relatively low amount of internet-exposed assets per company (34%). However, given that an average cyber loss in this industry has been shown to be about $45M, this is highly concerning (6). The Services industry (SIC Division I) is followed by Division E (Transportation, Communications, Electric, Gas, and Sanitary Services, with an average loss of around $58M), which is followed by Division D (Manufacturing, with an average loss of around $25M). The revenue range for companies with the highest number of compromised credentials is $1M-$10M, followed by $10M-$50M. A similar trend is also observed when evaluating company size by the number of employees. Indeed, companies with fewer employees have a higher share of compromised credentials. On average, the larger the company (both in terms of revenue and number of employees (7)), the greater the number of internet-exposed assets.There is a correlation between the industries and revenue ranges of companies targeted by ransomware and those with the highest share of compromised credentials.   âMethodologyâThe data for this research was collected as follows:âData regarding compromised credentials was first collected from Hudson Rock, a provider of various cybercrime data. Data was collected for the previous six months, beginning March 2023. This data | Ransomware Threat Studies Prediction Cloud | APT 39 APT 39 APT 17 | ★★★ |

IntroductionâIn this comprehensive report, Kovrr collected and analyzed data on all known ransomware attacks reported during the first two quarters of 2023. The data was collected from multiple sources, all aggregated and updated regularly in Kovrrâs Threat Intelligence Database. The database includes data on many different types of cyber incidents, but this report includes only data on ransomware attacks, excluding data on any other type of attacks. The ransomware groups covered in this report all operate as a RaaS (Ransomware as a Service), a business model through which the ransomware binary and operation are sold or leased to operators, called affiliates. This means that a ransomware operation is composed of many different individuals, with separate roles, and the extortion profits are divided between them. Some individuals are responsible for initial access to the targets, others to lateral movement to interesting and profitable areas in the victim network, while others are responsible for the ransomware infection itself, and others negotiate with the victim after infection. âSummaryâThese are the main insights from the collected data:There is a 32% drop in attack amounts in H1-23 compared to H2-22. It is important to note that this drop can also be due to delayed reporting of cyber incidents by attacked companies.The top ten most active groups observed during the first half of 2023 are AvosLocker, Bianlian, BlackBasta, BlackCat, Clop, Lockbit 3.0, MedusaLocker, Play, Royal, and ViceSociety. All 10 actors accounted for 87% of attacks during this period, while the top 3 groups (Lockbit 3.0, BlackCat, and Clop) accounted for 53% of all claimed attacks during this period. The average lifespan of a ransomware group is 262 days, while the median is 167 days. In an average month, 18.3 different ransomware groups are active.The most targeted industry is the Services industry, while companies with a revenue of $10M-$50M are the most common targets. âData Collection Methods and Possible BiasesâThe data for this research was collected from Kovrrâs Threat Intelligence Database, that collects data from multiple sources, and includes information on different types of cyber incidents. Specifically for this report, data was collected mainly from ransomware leak sites, public filings of attacked companies, and news reports on ransomware attacks. The data from ransomware leak sites was collected mainly from Double Extortion (https://doubleextortion.com), a data source providing up to date information from ransomware leak sites. The rest of the data was collected using proprietary sources and methods. This data was then combined with additional sources to collect company business information and is limited to ransomware attacks that occurred and were reported in the first two quarters of 2023, between January 1st 2023 and June 31st 2023. There are several possible biases in the data that may affect the results presented in the report. Data collection for this research relied either on a company filing a notification on a ransomware attack, or a ransomware group uploading information about a victim. Therefore, in the case that a company decided not to file a notice of a ransomware attack, for example due to not being legally required to do so, it will not be included in our data. This means that companies located in countries that require data breach notifications, such as companies in the United States or the European Union, are expected to have a higher representation in our data. This is also true for companies in more regulated industries, such as healthcare. Regarding data retrieved from ransom group sites, there may be cases where an attacker did not upload data on the attack victim, as the victim paid the ransom, or for other reasons. This means that some victims that have quickly paid ransoms following an attack might not appear in our data. Additionally,, we have previously researched | Ransomware Data Breach Vulnerability Threat Cloud | APT 17 | ★★★ |

2022-07-28 00:00:00 | 2022 semble être sur la cible de l'année la plus basse des violations signalées par les grandes sociétés américaines dans les six premiers mois de 2022, les grandes sociétés américaines [de revenus> 2 milliards] ont déclaré le moins de violations de données au cours des cinq dernières années. 2022 seems to be on target for the lowest year of reported breaches by large US corporationsIn the first six months of 2022, large [Revenue >2bn] US corporations reported the fewest data breaches in the past five years.Read More (lien direct) |
âThe number of data breaches reported in the first 6 months of 2022 has put this year on track to be the lowest year of reports in the last 5 years for large [Revenue >2bn] US corporations. By looking at the rate at which data breach events have been reported so far this year, we predict that the number of events reported is expected to be15-20% of the number of breaches reported in 2021âPossible causes:Increased reporting delays: But the time to report has shown a decreasing trend over the last 4 yearsGenuine improvement in cyber defenses preventing data exfiltration Reduction in reporting requirements, or public disclosure preventionIn this analysis we look at all the reported cyber events which involve data exfiltration (data breach), allocated to the year in which the event started. Comparing the number of events reported at each point during the year then gives us an indication for the rate which can be compared between years.The data and populationThe data collected represents public reports of data breaches from US companies with an annual revenue above $2bn (Excluding public services).The data used includes breach events reported up to end of Q2 2022It is this area where the cyber reporting requirements are highest, there is a high level of data available. It is important to note that this will not be all events which occur, only those disclosed, but by looking for changes in the behavior we can look at the potential causes.Overall Breach CountAs of the end of Q2 2022, we have seen 18 breach reports of events occurring in 2022 compared to the 160 cyber events reported from 2021, and 292 from 2020. While we are only 50% through 2022, the number of events reported so far from the first half is 25% of the 2021 total reported at the same point through 2021. To fully compare 2022 against prior years we need to take into account a number of factors:Events not yet reported: some events have occurred but have not yet been reported either because they have not yet been discovered, or because the have been discovered but not publicly disclosedEvents not yet occurred: events which have yet to occur, in the second half of 2022 (and have not yet been reported)âââHow the year unfoldsTo explore how 2022 is emerging, we can look at the rate at which events are being reported. That is to show not just the total report to date, but how the total number of events reported in a year has emerged from the start of the year. To do this we plot the cumulative number of events reported vs the number of days from the start of each incident year.What we see is an indication of how many incidents have been reported from each year have been reported after the same number of days. A steep curve indicates a greater number of incidents reported per month.** Note that the event counts are lower because we do not have exact disclosure dates for all events.ââFrom the chart we can see that the number of reported cyber incidents after 6 months (180 days) of experience is low for 2022 compared with all other years since 2015. This leads us to believe that 2022 is on track to have a very low number of overall incidents reported.There could be a few explanations for thisReporting Delay: The time taken to report incidents has increased in 2022, and there will be a correction in the later part of the yearCybersecurity Investment: The overall number of incidents reported will be lower due to improvements in security postureRegulatory Action: the overall number of incidents reported will be lower due to changes in how the events are reported (or required to be reported)âReporting DelayTo consider if the low reported number of events in 2022 is being driven by an increase in a delay between a cyber event starting and it being reported, we have looked at the trend over the last 10 yearsThe chart below shows the trend over the last 10 years.âââThere has been a steady reduction in median reporting delay from 204 days in 2017 to 63 days | Data Breach Prediction Cloud | ★★★ | |

2022-01-19 00:00:00 | Quelles tendances émergentes de cybersécurité devraient-elles être conscientes? Alors que le monde devient plus connecté numériquement, les entreprises doivent être conscientes des risques croissants de cybersécurité. What Emerging Cybersecurity Trends Should Enterprises Be Aware Of?As the world becomes more digitally connected, enterprises need to be aware of the growing cybersecurity risks.Read More (lien direct) |
As the world becomes more digitally connected every year â and with the pandemic further accelerating digital transformation â all types of enterprises need to be aware of the growing cybersecurity risks that come with this shift. In Europe, for example, significant attacks on critical sectors more than doubled in 2020 compared to 2019, according to data from the European Union Agency for Cybersecurity, as reported by CNN. In 2021, the picture arguably became even bleaker around the world, with major ransomware attacks causing disruption to companies in industries ranging from energy to meat processing.In the first six months of 2021 alone, ransomware-related reported activity in the U.S. had a higher total value ($590 million) than all ransomware-related reported suspicious activity in the U.S. in 2020, according to the U.S. Department of Treasury\'s Financial Crimes Enforcement Network (FinCEN). The total number of suspicious events filed in the first six months of 2021 in the U.S. also exceeded all of what occurred in the country in 2020 by 30%, the agency reports. Yet itâs not just ransomware thatâs wreaking havoc. Enterprises also need to be prepared for cyber threats like denial of service (DoS) attacks, where a flood of network activity can interrupt servers, thereby causing business interruption. Cisco predicts that distributed denial of service (DDoS) attacks (a subset of DoS, which involves using multiple devices to send a flood of traffic, as opposed to just using one device with a DoS attack) globally will roughly âdouble from 7.9 million in 2018 to 15.4 million by 2023.âIn addition to preparing for these types of cyberattacks, enterprises will also increasingly need to be aware of and comply with privacy-related regulations. As governments around the world try to bolster their cybersecurity responses, they are passing or at least considering new rules and guidance around how companies need to handle sensitive data and privacy issues. Amidst this preparation, enterprises also need to recognize that cybersecurity plans arenât foolproof, especially as attacks evolve. That means assets could be at risk even with solid defenses in place. So, enterprises increasingly need to think about not just how to prevent cyber attacks but also consider the dollar-value cost of risk, given that events will inevitably occur. This process, known as cyber risk quantification â a form of financial quantification â helps enterprises think about and discuss cyber risk in definitive business terms. Knowing how much money is at stake and how different cyber events could affect revenue and profit can help businesses prioritize defenses and take mitigating action like securing cyber insurance. In this report, weâll take a closer look at these emerging cybersecurity trends that enterprises should be aware of. Understanding these areas can help organizations potentially improve their risk management, both from a cybersecurity and overall governance standpoint. ââEvolving Ransomware RisksWhile ransomware is not a new type of threat, the scale and intensity of ransomware continue to broaden. Enterprises large and small, across all types of industries, need to be prepared for these cyber attacks.For one, ransomware-as-a-service, âwhere ransomware variants are licensed to individuals and accomplices to execute attacks,â as Reuters explains, has been on the rise. Based on suspicious activity reports, FinCEN identified 68 ransomware variants in the first half of 2021.âThe resulting emergence of new attackers has led to increased uncertainty and volatility for companies in responding to attacks due to the lack of information on the growing number of ransomware threat actors,â adds Reuters.Part of the problem is also that ransomware attacks arenât just being launched on an ad-hoc basis by individuals.

2020-11-17 00:00:00 | CRIMZONâ¢: The Data Behind the FrameworkA report that highlights a subset of the empirical validation for the CRIMZON⢠framework.Read More (lien direct) | âAbstract The CRIMZON⢠framework defines the minimal elements needed to provide a view of accumulated cyber risk. For natural catastrophe risk, individual policy exposures can be aggregated within geographic zones.Similarly, cyber exposures can be aggregated using CRIMZONâ¢. Location also holds importance when assessing cyber catastrophe risk, however, two additional elements must be taken into account to properly assess cyber risk accumulation: industry and company size. Insured companies with common characteristics related to location, industry, and entity size tend to be exposed to similar types of cyber events because these elements also correspond to technologies or service providers used. Based on an analysis of millions of cyber events in the last 20 years, Kovrr conducted extensive research, to serve as the core empirical validation for the CRIMZON framework. Below is a subset of the research, in which a study group of 120 CRIMZON was determined by selecting CRIMZON with the highest relevance to the cyber insurance market(he research group was compiled according to criteria detailed in (Appendix A) The total number of unique companies in the study group is 20,000, with an average number of 152 companies within a CRIMZON, and a median of 86 companies. The research criteria focused on companiesâ location industry, entity size, and the hosting and mail technology and service providers used by companies. The results showed a concentration of technologies and services when grouping by location, and further concentration when adding the additional elements of the CRIMZON, entity size and industry to the analysis. The research shows that companies within the same CRIMZON have the tendency to use the same service providers and technologies, and that different compositions of service providers and technologies can be found across CRIMZON. When trying to estimate accumulations of potential losses from cyber, insurance and reinsurance companies face two main challenges: identifying which policies are exposed to the same cyber events and determining how many policies will be affected at the same time. The former is related to the problem of enumerating all technologies and service providers each insured relies upon, the latter is equivalent to estimating the footprint of a cyber event. Analyzing accumulations by CRIMZON enables risk professionals to make sense of the size and extent of potential losses from cyber, without necessarily needing to collect detailed information about technologies and service providers for each insured. The framework is completely agnostic to the line of business, therefore unlocking a full range of possible applications across both silent and affirmative cyber coverages. Among these applications is the development of aggregate models. This research shows it is possible to estimate the two key ingredients needed for the development of industry loss curves, the hazard and the exposure, using the CRIMZON as the atomic unit of aggregation. By identifying the correlation across CRIMZON, an aggregate model can then be developed.âIntroduction - What are CRIMZONâ¢? The Cyber Risk Accumulation Zones (CRIMZONâ¢) framework defines the minimal elements needed to provide a view of aggregated cyber exposure. Kovrr launched CRIMZON during participation in the fourth cohort of the Lloydâs Lab, the insurance technology accelerator operated by Lloydâs of London. CRIMZON is an open framework created to facilitate better communication across players in the cyber insurance value chain. The framework allows users to overlay their data pertaining to loss, cyber attack frequency, as well as additional data onto the CRIMZON for additional insights of risk per zone and to detect correlations between different zones. The framework was created to support efforts for setting a standard for data collection for cyber risk management.The CRIMZON are composed of the following three elements:Location - country-level worldwide a | Vulnerability Studies Cloud | ★★★ |
