Ransomware programs
Quarterly trends and highlights
Attacks on Linux and VMWare ESXi servers
An increasing number of ransomware families are extending their attack surfaces by adding support for operating systems other than Windows, which they have targeted traditionally. In Q1 2023, we discovered builds from several ransomware families intended for running on Linux and VMWare ESXi servers, namely: ESXiArgs (new family), Nevada (a rebranding of Nokoyawa, which is written in Rust), Royal, IceFire.
Thus, the arsenals of most professional extortion groups today include ransomware builds designed for several platforms, thus maximizing the damage they can cause to their victims.
Progress in combating cybercrime
Europol and the U.S. Department of Justice announced that as a result of a joint operation with the FBI that started in July 2022, the FBI penetrated networks belonging to the Hive group and obtained decryption keys for more than 1,300 victims. The law enforcement agencies also obtained information about 250 Hive affiliates and seized several servers belonging to the group.
The Netherlands Police arrested three individuals suspected of stealing confidential data and extorting €100,000 to €700,000 from each victim company.
Europol announced it had arrested two suspected core members of DoppelPaymer during a joint operation with the FBI and the law enforcement agencies of Germany, Ukraine, and the Netherlands. The team also seized hardware, which the law enforcement agencies will inspect during further investigation.
Conti-based Trojan decrypted
Kaspersky analysts released a utility for decrypting files affected by a Trojan known to researchers as MeowCorp. The malware was compiled from Conti source code, which was published last year. An archive containing the secret keys, 258 in all, was posted on an online forum. We added these, along with data decryption code, to the latest version of RakhniDecryptor.
Most prolific groups
This section looks at ransomware groups that engage in so-called “double extortion”, that is stealing confidential data in addition to encrypting it. Most of these groups target large companies, and many maintain a DLS (data leak site), where they publish a list of organizations they have attacked. The diagram below reflects the most prolific extortion gangs, that is, the ones that added the largest numbers of victims to their DLSs.

Number of new modifications
In Q1 2023, we detected nine new ransomware families and 3089 new modifications of the malware of this type.

Vulnerable applications used in cyberattacks
Quarterly highlights
Q1 2023 saw a number of Windows vulnerabilities remediated and published. Some of those were the following:
- CVE-2023-23397: probably the most high-profile vulnerability, which provoked much online debate and discussion. This Windows vulnerability allows starting automatic authentication on behalf of the user on a host running Outlook.
- CVE-2023-21674: a vulnerability in the ALPC subsystem that allows a malicious actor to escalate their privileges to system level.
- CVE-2023-21823: a Windows Graphics Component vulnerability that allows running commands in the system on behalf of the user. This can be reproduced both in Windows desktop versions of Microsoft Office and in mobile (iOS and Android) versions.
- CVE-2023-23376: a Common Log File System Driver vulnerability that allows escalating privileges to system level.
- СVE-2023-21768: a vulnerability in the Ancillary Function Driver for WinSock that allows obtaining system privileges.
A Microsoft fix for each of the vulnerabilities is out, and we strongly encourage you to install all the relevant patches.
The main network threats in Q1 2023 were brute-force attacks on MSSQL and RDP services. EternalBlue and EternalRomance remained popular exploits for operating system vulnerabilities. We detected notably large numbers of attacks and scans that targeted log4j-type vulnerabilities (CVE-2021-44228).
Vulnerability statistics
In Q1 2023, Kaspersky products detected more than 300,000 exploitation attempts, most of these using Microsoft Office exploits. Their share was 78.96%, down by just 1 p.p. from the previous quarter. The most-exploited vulnerabilities in that category were the following:
- CVE-2017-11882 and CVE-2018-0802: Equation Editor vulnerabilities that allow corrupting application memory during formula processing to then run arbitrary code in the system.
- CVE-2017-0199 that allows using MS Office to load malicious scripts.
- CVE-2017-8570 that allows loading malicious HTA scripts into the system.
The second most-exploited category were browser vulnerabilities (7.07%), their share growing by 1 p.p. We did not discover any new browser vulnerabilities exploited by malicious actors in the wild. Q2 2023 might bring something new.
Distribution of exploits used by cybercriminals by type of attacked application, Q1 2023 (download)
Android (4.04%) and Java (3.93%) were third and fourth, respectively. Android exploits lost 1 p.p. during the period, whereas the share of Java exploits remained unchanged. The fifth- and sixth-place scores — Adobe Flash (3.49%) and PDF (2.52%) — were very close to the previous quarter’s figures as well.
Attacks on macOS
The first quarter’s high-profile event was a supply-chain attack on the 3CX app, including the macOS version. Hackers were able to embed malicious code into the libffmpeg media processing library to download a payload from their servers.
Worth noting is the MacStealer spy program, also discovered in Q1 2023, which stole cookies from the victim’s browser, as well as account details and cryptowallet passwords.

* Unique users who encountered this malware as a percentage of all users of Kaspersky security products for macOS who were attacked.
Adware remained the most widespread threat to macOS users. In addition to that, we frequently came across all kinds of system “cleaners” and “optimizers”, many of these containing highly annoying ads or classic scams, where users were offered to buy solutions to problems that did not exist.

Attacks via web resources
The statistics in this section are based on Web Anti-Virus, which protects users when malicious objects are downloaded from malicious/infected web pages. Cybercriminals create these sites on purpose; they can infect hacked legitimate resources as well as web resources with user-created content, such as forums.
Countries/territories that serve as sources of web-based attacks: TOP 10
The following statistics show the distribution by country/territory of the sources of internet attacks blocked by Kaspersky products on user computers (web pages with redirects to exploits, sites hosting malicious programs, botnet C&C centers, etc.). Any unique host could be the source of one or more web-based attacks.
To determine the geographic source of web attacks, the GeoIP technique was used to match the domain name to the real IP address at which the domain is hosted.
In Q1 2023, Kaspersky solutions blocked 865,071,227 attacks launched from online resources across the globe. A total of 246,912,694 unique URLs were detected as malicious by Web Anti-Virus.

Countries/territories where users faced the greatest risk of online infection
To assess the risk of online infection faced by users in various countries/territories, we calculated the percentage of Kaspersky users on whose computers Web Anti-Virus was triggered at least once during the quarter in each country/territory. The resulting data provides an indication of the aggressiveness of the environment in which computers operate in various countries.
Note that these rankings only include attacks by malicious objects that fall under the Malware class; they do not include Web Anti-Virus detections of potentially dangerous or unwanted programs, such as RiskTool or adware.

On average during the quarter, 9.73% of internet users’ computers worldwide were subjected to at least one Malware-class web attack.
Local threats
In this section, we analyze statistical data obtained from the OAS and ODS modules of Kaspersky products. It takes into account malicious programs that were found directly on users’ computers or removable media connected to them (flash drives, camera memory cards, phones, external hard drives), or which initially made their way onto the computer in non-open form (for example, programs in complex installers, encrypted files, etc.).
In Q1 2023, our File Anti-Virus detected 43,827,839 malicious and potentially unwanted objects.
Countries and territories where users faced the highest risk of local infection
For each country/territory, we calculated the percentage of Kaspersky product users on whose computers File Anti-Virus was triggered during the reporting period. These statistics reflect the level of personal computer infection in different countries/territories.
