Quarterly trends and highlights
Law enforcement successes
- Several members of the REvil ransomware crime group were arrested by Russian law enforcement in January. The Russian Federal Security Service (FSB) says it seized the following assets from the cybercriminals: “more than 426 million rubles ($5.6 million) including denominated in cryptocurrency; $600,000; 500,000 euros; computer equipment, the crypto wallets that were used to perpetrate crimes, and 20 luxury cars that were purchased with illicitly obtained money.”
- In February, a Canadian citizen was sentenced to 6 years and 8 months in prison for involvement in NetWalker ransomware attacks (also known as Mailto ransomware).
- In January, Ukrainian police arrested a ransomware gang who delivered an unclarified strain of malware via e-mail. According to the statement released by the police, over fifty companies in the United States and Europe were attacked by the cybercriminals.
HermeticWiper, HermeticRansom and RUransom, etc.
In February, new malware was discovered which carried out attacks with the aim of destroying files. Two pieces of malware — a Trojan called HermeticWiper that destroys data and a cryptor called HermeticRansom — were both used in cyberattacks in Ukraine. That February, Ukrainian systems were attacked by another Trojan called IsaacWiper, followed by a third Trojan in March called CaddyWiper. The apparent aim of this malware family was to render infected computers unusable leaving no possibility of recovering files.
An intelligence team later discovered that HermeticRansom only superficially encrypts files, and ones encrypted by the ransomware can be decrypted.
RUransom malware was discovered in March, which was created to encrypt files on computers in Russia. The analysis of the malicious code revealed it was developed to wipe data, as RUransom generates keys for all the victim’s encrypted files without storing them anywhere.
Conti source-code leak
The ransomware group Conti had its source code leaked along with its chat logs which were made public. It happened shortly after the Conti group expressed support for the Russian government’s actions on its website. The true identity of the individual who leaked the data is currently unknown. According to different versions, it could have been a researcher or an insider in the group who disagrees with its position.
Whoever it may have been, the leaked ransomware source codes in the public domain will obviously be at the fingertips of other cybercriminals, which is what happened on more than one occasion with examples like Hidden Tear and Babuk.
Attacks on NAS devices
Network-attached storage (NAS) devices continue to be targeted by ransomware attacks. A new wave of Qlocker Trojan infections on QNAP NAS devices occurred in January following a brief lull which lasted a few months. A new form of ransomware infecting QNAP NAS devices also appeared in the month of January called DeadBolt, and ASUSTOR devices became its new target in February.
Master decryption keys for Maze, Sekhmet and Egregor ransomware were made public in February. The keys turned out to be authentic and we increased our support to decrypt files encrypted by these infamous forms of ransomware in our RakhniDecryptor utility. The decryptor is available on the website of our No Ransom project and the website of the international NoMoreRansom project in the Decryption Tools section.

Vulnerable applications used by criminals during cyberattacks
In Q1 2022, a number of serious vulnerabilities were found in Microsoft Windows and its components. More specifically, the vulnerability CVE-2022-21882 was found to be exploited by an unknown group of cybercriminals: a “type confusion” bug in the win32k.sys driver the attacker can use to gain system privileges. Also worth noting is CVE-2022-21919, a vulnerability in the User Profile Service which makes it possible to elevate privileges, along with CVE-2022-21836, which can be used to forge digital certificates.
One of the major talking points in Q1 was an exploit that targeted the CVE-2022-0847 vulnerability in the Linux OS kernel. It was dubbed “Dirty Pipe”. Researchers discovered an “uninitialized memory” vulnerability when analyzing corrupted files, which makes it possible to rewrite a part of the OS memory, namely page memory that contains system files’ data. This in turn opens up an opportunity, such as elevating attacker’s privileges to root. It’s worth noting that this vulnerability is fairly easy to exploit, which means users of all systems should regularly install security patches and use all available means to prevent infection.
When it comes to network threats, this quarter continued to show how cybercriminals often resort to the technique of brute-forcing passwords to gain unauthorized access to various network services, the most popular of which are MSSQL, RDP and SMB. Attacks using the EternalBlue, EternalRomance and similar exploits remain as popular as ever. Due to widespread unpatched versions of Microsoft Exchange Server, networks often fall victim to exploits of ProxyToken, ProxyShell, ProxyOracle and other vulnerabilities. One example of a critical vulnerability found is remote code execution (RCE) in the Microsoft Windows HTTP protocol stack which allows an attack to be launched remotely by sending a special network packet to a vulnerable system by means of the HTTP trailer functionality. New attacks on network applications which will probably also become common are RCE attacks on the popular Spring Framework and Spring Cloud Gateway. Specific examples of vulnerabilities in these applications are CVE-2022-22965 (Spring4Shell) and CVE-2022-22947.
Q1 2022 saw an array of changes in the statistics on common vulnerability types. For instance, the top place in the statistics is still firmly held by exploits targeting vulnerabilities in Microsoft Office and their share has increased significantly to 78.5%. The same common vulnerabilities we’ve written about on more than one occasion are still the most widely exploited within this category of threats. These are CVE-2017-11882 and CVE-2018-0802, which cause a buffer overflow when processing objects in a specially crafted document in the Equation Editor component and ultimately allow an attacker to execute arbitrary code. There’s also CVE-2017-8570, where opening a specially crafted file with an affected version of Microsoft Office software gives attackers the opportunity to perform various actions on the vulnerable system. Another vulnerability found last year which is very popular with cybercriminals is CVE-2021-40444, which they can use to exploit through a specially prepared Microsoft Office document with an embedded malicious ActiveX control for executing arbitrary code in the system.

Exploits targeting browsers came second again in Q1, although their share dropped markedly to just 7.64%. Browser developers put a great deal of effort into patching vulnerability exploits in each new version and closing a large number of gaps in system security. Apart from that, the majority of browsers have automatic updates as opposed to the distinct example of Microsoft Office, where many of its users still use outdated versions and are in no rush to install security updates. That could be precisely the reason why we’ve seen a reduction in the share of browser exploits in our statistics. However, this does not mean they’re no longer an immediate threat. For instance, Chrome’s developers fixed a number of critical RCE vulnerabilities, including:
- CVE-2022-1096: a “type confusion” vulnerability in the V8 script engine which gives attackers the opportunity to remotely execute code (RCE) in the context of the browser’s security sandbox.
- CVE-2022-0609: a use-after-free vulnerability which allows to corrupt the process memory and remotely execute arbitrary codes when performing specially generated scripts that use animation.
Similar vulnerabilities were found in the browser’s other components: CVE-2022-0605which uses Web Store API, and CVE-2022-0606 which is associated with vulnerabilities in the WebGL backend (ANGLE). Another vulnerability found was CVE-2022-0604, which can be used to exploit a heap buffer overflow in Tab Groups, also potentially leading to remote code execution (RCE).
Exploits for Android came third in our statistics (4.10%), followed by exploits targeting the Adobe Flash Platform (3.49%), PDF files (3.48%) and Java apps (2.79%).
Attacks on macOS
The year began with a number of interesting multi-platform finds: the Gimmick multi-platform malware family with Windows and macOS variants that uses Google Drive to communicate with the C&C server, along with the SysJoker backdoor with versions tailored for Windows, Linux and macOS.
TOP 20 threats for macOS
* Unique users who encountered this malware as a percentage of all users of Kaspersky security solutions for macOS who were attacked.
The TOP 20 threats to users detected by Kaspersky security solutions for macOS is usually dominated by various adware apps. The top two places in the rating were taken by adware apps from the AdWare.OSX.Pirrit family, while third place was taken by a member of the Monitor.OSX.HistGrabber.b family of potentially unwanted software which sends users’ browser history to its owners’ servers.

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 such sites on purpose and web resources with user-created content (for example, forums), as well as hacked legitimate resources, can be infected.
Countries and territories that serve as sources of web-based attacks: TOP 10
The following statistics show the distribution by country or 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 2022, Kaspersky solutions blocked 1,216,350,437 attacks launched from online resources across the globe. 313,164,030 unique URLs were recognized as malicious by Web Anti-Virus components.
