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 | ★★★ |
