Ransomware programs

In the second quarter, the Lockbit group launched a bug bounty program. The cybercriminals are promising $1,000 to $1,000,000 for doxing of senior officials, reporting  web service, Tox messenger or ransomware Trojan algorithm vulnerabilities, as well as for ideas on improving the Lockbit website and Trojan. This was the first-ever case of ransomware groups doing a (self-promotion?) campaign like that.

Another well-known group, Conti, said it was shutting down operations. The announcement followed a high-profile attack on Costa Rica’s information systems, which prompted the government to declare a state of emergency. The Conti infrastructure was shut down in late June, but some in the infosec community believe that Conti members are either just rebranding or have split up and joined other ransomware teams, including Hive, AvosLocker and BlackCat.

While some ransomware groups are drifting into oblivion, others seem to be making a comeback. REvil’s website went back online in April, and researchers discovered a newly built specimen of their Trojan. This might have been a test build, as the sample did not encrypt any files, but these events may herald the impending return of REvil.

Kaspersky researchers found a way to recover files encrypted by the Yanluowang ransomware and released a decryptor for all victims. Yanluowang has been spotted in targeted attacks against large businesses in the US, Brazil, Turkey, and other countries.

Number of new modifications

In Q2 2022, we detected 15 new ransomware families and 2355 new modifications of this malware type.

Vulnerable applications used by criminals during cyberattacks

Quarterly highlights

During Q2 2022, a number of major vulnerabilities were discovered in the Microsoft Windows. For instance, CVE-2022-26809 critical error allows an attacker to remotely execute arbitrary code in a system using a custom RPC request. The Network File System (NFS) driver was found to contain two RCE vulnerabilities: CVE-2022-24491 and CVE-2022-24497. By sending a custom network message via the NFS protocol, an attacker can remotely execute arbitrary code in the system as well. Both vulnerabilities affect server systems with the NFS role activated. The CVE-2022-24521 vulnerability targeting the Common Log File System (CLFS) driver was found in the wild. It allows elevation of local user privileges, although that requires the attacker to have gained a foothold in the system. CVE-2022-26925, also known as LSA Spoofing, was another vulnerability found during live operation of server systems. It allows an unauthenticated attacker to call an LSARPC interface method and get authenticated by Windows domain controller via the NTLM protocol. These vulnerabilities are an enduring testament to the importance of timely OS and software updates.

Most of the network threats detected in Q2 2022 had been mentioned in previous reports. Most of those were attacks that involved brute-forcing  access to various web services. The most popular protocols and technologies susceptible to these attacks include MS SQL Server, RDP and SMB. Attacks that use the EternalBlue, EternalRomance and similar exploits are still popular. Exploitation of Log4j vulnerability (CVE-2021-44228) is also quite common, as the susceptible Java library is often used in web applications. Besides, the Spring MVC framework, used in many Java-based web applications, was found to contain a new vulnerability CVE-2022-22965 that exploits the data binding functionality and results in remote code execution. Finally, we have observed a rise in attacks that exploit insecure deserialization, which can also result in access to remote systems due to incorrect or missing validation of untrusted user data passed to various applications.

Vulnerability statistics

Exploits targeting Microsoft Office vulnerabilities grew in the second quarter to 82% of the total. Cybercriminals were spreading malicious documents that exploited CVE-2017-11882 and CVE-2018-0802, which are the best-known vulnerabilities in the Equation Editor component. Exploitation involves the component memory being damaged and a specially designed script, run on the target computer. Another vulnerability, CVE-2017-8570, allows downloading and running a malicious script when opening an infected document, to execute various operations in a vulnerable system. The emergence of CVE-2022-30190or Follina vulnerability also increased the number of exploits in this category. An attacker can use a custom malicious document with a link to an external OLE object, and a special URI scheme to have Windows run the MSDT diagnostics tool. This, in turn, combined with a special set of parameters passed to the victim’s computer, can cause an arbitrary command to be executed — even if macros are disabled and the document is opened in Protected Mode.

Distribution of exploits used by cybercriminals, by type of attacked application, Q2 2022 (download)

Attempts at exploiting vulnerabilities that affect various script engines and, specifically, browsers, dipped to 5%. In the second quarter, a number of critical RCE vulnerabilities were discovered in various Google Chrome based browsers: CVE-2022-0609, CVE-2022-1096, and CVE-2022-1364. The first one was found in the animation component; it exploits a Use-After-Free error, causing memory damage, which is followed by the attacker creating custom objects to execute arbitrary code. The second and third vulnerabilities are Type Confusion errors associated with the V8 script engine; they also can result in arbitrary code being executed on a vulnerable user system. Some of the vulnerabilities discovered were found to have been exploited in targeted attacks, in the wild. Mozilla Firefox was found to contain a high-risk Use-After-Free vulnerability, CVE-2022-1097, which appears when processing NSSToken-type objects from different streams. The browser was also found to contain CVE-2022-28281, a vulnerability that affects the WebAuthn extension. A compromised Firefox content process can write data out of bounds of the parent process memory, thus potentially enabling code execution with elevated privileges. Two further vulnerabilities, CVE-2022-1802 and CVE-2022-1529, were exploited in cybercriminal attacks. The exploitation method, dubbed “prototype pollution”, allows executing arbitrary JavaScript code in the context of a privileged parent browser process.

As in the previous quarter, Android exploits ranked third in our statistics with 4%, followed by exploits of Java applications, the Flash platform, and PDF documents, each with 3%.

Attacks on macOS

The second quarter brought with it a new batch of cross-platform discoveries. For instance, a new APT group Earth Berberoka (GamblingPuppet) that specializes in hacking online casinos, uses malware for Windows, Linux, and macOS. The TraderTraitor campaign targets cryptocurrency and blockchain organizations, attacking with malicious crypto applications for both Windows and macOS.

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.

TOP 10 countries and territories that serve as sources of web-based attacks

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 Q2 2022, Kaspersky solutions blocked 1,164,544,060 attacks launched from online resources across the globe. A total of 273,033,368 unique URLs were recognized as malicious by Web Anti-Virus components.
