Kaspersky offers various services to organizations that have been targeted by cyberattackers, such as incident response, digital forensics, and malware analysis. In our annual incident response report, we share information about the attacks that we investigated during the reporting period. Data provided in this report comes from our daily interactions with organizations seeking assistance with full-blown incident response or complementary expert services for their internal incident response teams.

Kaspersky Incident Response in various regions and industries

In 2022, 45.9% of organizations that encountered cyberincidents were in Russia and the CIS region, followed by the Middle East (22.5%), the Americas (14.3%), and Europe (13.3%).

From an industry perspective, we offered help to government (19.39%), financial (18.37%), and industrial (17.35%) organizations most frequently.

In 2022, attackers most often penetrated organizations’ infrastructure by exploiting various vulnerabilities in public-facing applications (42.9%). However, compared to 2021, the share of this initial attack vector decreased by 10.7 pp, while the share of attacks involving compromised accounts (23.8%) grew. Malicious e-mail sharing among the initial attack vectors continued to go down and comprised 11.9% in 2022.

In 39.8% cases the reported incidents were related to ransomware attacks. Encrypted data remains the number-one problem that our customers are faced with. However, compared to 2021, the number of ransomware-related incidents dropped, and not every attack involving file encryption was aimed at extracting a ransom. In some of these incidents, ransomware was used to hide the initial traces of the attack and complicate the investigation.

Expert recommendations

To protect your organization against cyberattacks, Kaspersky experts recommend the following:

  • Implement a robust password policy and enforce multifactor authentication
  • Remove management ports from public access
  • Establish a zero-tolerance policy for patch management or compensation measures for public-facing applications
  • Make sure that your employees maintain a high level of security awareness
  • Use a security toolstack with EDR-like telemetry
  • Implement rules for detection of pervasive tools used by adversaries
  • Continuously train your incident response and security operations teams to maintain their expertise and stay up to speed with the changing threat landscape
  • Back up your data on a regular basis
  • Work with an Incident Response Retainer partner to address incidents with fast SLAs

  • Reports

    For more than five years, the Global Research and Analysis Team (GReAT) at Kaspersky has been publishing quarterly summaries of advanced persistent threat (APT) activity. These summaries are based on our threat intelligence research; and they provide a representative snapshot of what we have published and discussed in greater detail in our private APT reports.

    We continued to track Tomiris as a separate threat actor over three new attack campaigns between 2021 and 2023, and our telemetry allowed us to shed light on the group. In this blog post, we’re excited to share what we now know of Tomiris with the broader community, and discuss further evidence of a possible connection to Turla.

    The Lazarus group is a high-profile Korean-speaking threat actor with multiple sub-campaigns. In this blog, we’ll focus on an active cluster that we dubbed DeathNote.

    A DLL named guard64.dll, which was loaded into the infected 3CXDesktopApp.exe process, was used in recent deployments of a backdoor that we dubbed “Gopuram” and had been tracking internally since 2020.
