Vulnerable applications used by cybercriminals

In 2020, most vulnerabilities were discovered by researchers before attackers could exploit them. However, there was no doing without zero-day vulnerabilities, of which Kaspersky found:

  • CVE-2020-1380, a use-after-free vulnerability in the Jscript9 component of Microsoft’s Internet Explorer browser caused by insufficient checks during the generation of optimized JIT code. This vulnerability was most likely used by the APT group DarkHotel at the first stage of system compromise, after which the payload was delivered by an additional exploit that escalated privileges in the system;
  • CVE-2020-0986 in the GDI Print/Print Spooler component of Microsoft’s Windows operating system, enabling manipulation of process memory for arbitrary code execution in the context of a system service process. Exploitation of this vulnerability gives attackers the ability to bypass sandboxes, for example, in the browser.

The first quarter of 2021 turned out to be rich not only in well-known vulnerabilities, but also in zero-day ones. In particular, both IT security specialists and cybercriminals showed great interest in the new Microsoft Exchange Server vulnerabilities:

  • CVE-2021-26855 — a Service-Side Request Forgery vulnerability that allows an attacker to make a forged server request and execute arbitrary code (RCE);
  • CVE-2021-26857 — insecure object deserialization by the Unified Messaging service, which can lead to arbitrary code execution on the server side;
  • CVE-2021-26858 — allows an attacker to write data to server files, which can also lead to remote code execution;
  • CVE-2021-27065 — similar to CVE-2021-26858, this vulnerability allow an authorized Microsoft Exchange user to write arbitrary code to system files.

These vulnerabilities were found in-the-wild and had been used by APT and ransomware groups.

One more constellation of vulnerabilities that appeared in the infosec sky was a threesome of critical bugs in the popular SolarWinds Orion Platform – CVE-2021-25274, CVE-2021-25275, CVE-2021-25276. Successful exploitation of any of them can cause infection of the system where the platform is installed (mostly, enterprise and government PCs).

Distribution of exploits used in attacks by type of application attacked, May 2020 – April 2021 (download)

The rating of vulnerable applications is based on verdicts by Kaspersky products for blocked exploits used by cybercriminals both in network attacks and in vulnerable local apps, including on users’ mobile devices.

Network attacks were the most common method of system penetration, and a significant portion of them is made up of brute-force attacks on various network services: RDP, Microsoft SQL Server, etc. In addition, the year gone by demonstrated that everything in the Windows operating system is cyclical, and that most of the detected vulnerabilities exist in the same services, for example, in the drivers of the SMB (SMBGhost, SMBBleed), DNS (SigRed) and ICMPv6 (BadNeighbor) network protocols. Two critical vulnerabilities (CVE-2020-0609, CVE-2020-0610) were found in the Remote Desktop Gateway service. An interesting vulnerability, dubbed Zerologon, was also discovered in the NetLogon service. In Q1 2021, researchers found three new vulnerabilities in Windows network stack code related to IPv4/IPv6 protocols processing — CVE-2021-24074, CVE-2021-24086 and CVE-2021-24094. Lastly, despite the fact that exploits for the EternalBlue and EternalRomance families are old, they are still used by attackers.

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 that are sources of web-based attacks

The following statistics show the distribution by country of the sources of Internet attacks blocked by Kaspersky products on user computers (web pages with redirects to exploits, sites containing exploits and other malicious programs, botnet C&C centers, etc.). Any unique host could be the source of one or more web-based attacks.

To determine the geographical source of web-based attacks, domain names are matched against their actual domain IP addresses, and then the geographical location of the specific IP address (GeoIP) is established.

Kaspersky solutions in the EU blocked 115,452,157 attacks launched from online resources across the globe. Moreover, 89.33% of these resources were located in just 10 countries.

Countries where users faced the greatest risk of online infection

To assess the risk of online infection faced by EU users, for each country we calculated the percentage of Kaspersky users on whose computers Web Anti-Virus was triggered during the reporting period. The resulting data provides an indication of the aggressiveness of the environment in which computers operate in different countries.

This rating only includes attacks by malicious programs that fall under the Malware class; it does not include Web Anti-Virus detections of potentially dangerous or unwanted programs such as RiskTool or adware. Overall, during the reporting period, adware and its components were registered on 89.60% of users’ computers on which Web Anti-Virus was triggered.

Local threats

Statistics on local infections of user computers is an important indicator. They include objects that penetrated the target computer through infecting files or removable storage media, or initially made their way onto the computer in non-open form (for example, programs in complex installers, encrypted files, etc.). These statistics additionally include objects detected on user computers after the first system scan by Kaspersky’s Anti-Virus application.

This section analyzes statistics produced by Anti-Virus scans of files on the hard drive at the moment they were created or accessed, as well as the results of scanning removable storage media.

Countries where users faced the highest risk of local infection

For each country in the EU, we calculated how often users there encountered a File Anti-Virus triggering during the year. Included are detections of objects found on user computers or removable media connected to them (flash drives, camera/phone memory cards, external hard drives). These statistics reflect the level of personal computer infection in different countries.

Phishing in the EU

  • Cloud phishing

    We observed that the number of EU-targeted phishing resources on cloud platforms and hosting sites approximately doubled during the reporting period.

  • Cryptocurrency

    The number of cryptocurrency-related phishing detections tripled. This category consists of fraudulent sites somehow linked to cryptocurrencies: in most cases, they are fake crypto exchanges that require users to invest money to gain access to an account that allegedly already contain complimentary currency. In fact, users just lose their own money if they try to buy access to such sites.

    Another particularly interesting type of phishing we observed in the EU is a mixture of cryptocurrency and COVID-19 themes: fake sites offering COVID-19 vaccines for cryptocurrency.

    Example of fake COVID-19 vaccine offer

  • Targeted extortion

    In late August 2020, we saw some unusual extortion messages. In them, cybercriminals claimed to have planted TNT somewhere in the recipient’s office, saying it would be detonated unless a ransom was paid or if police activity was observed near the building.

    Whereas individuals are asked to cough up the equivalent of $500–1,000 in bitcoin (the maximum we saw was around $5,000), for companies supposedly rigged with explosives the amount rises to roughly $20,000. The bulk of the scam e-mails are written in German, but we found English versions as well.

  • Microsoft Office spear phishing

    The trend for harvesting Microsoft 365 credentials through spear phishing continues to evolve. Such phishing e-mails normally contain a hyperlink to a fake website. Sure enough, once many people had absorbed that simple precaution, phishers began replacing the links with attached HTML files, the sole purpose of which is to automate redirection. Clicking on the HTML attachment opens it in a browser. As far as the phishing aspect goes, the file has just one line of code (javascript: window.location.href) with the phishing website address as a variable. It forces the browser to open the website in the same window.

Phishing attacks

In total, 86,584,675 phishing attempts were blocked by Kaspersky solutions in the EU, representing 21.89% of all phishing attacks around the world during the reporting period.

Organizations under attack

The rating of organizations targeted by phishers is based on the triggering of the deterministic component in the Anti-Phishing system on user computers. The component detects all pages with phishing content that the user has tried to open by following a link in an e-mail message or on the web, as long as links to these pages are present in the Kaspersky database.

Pandemic-related events affected the distribution of phishing attacks across the categories of targeted organizations. However, the largest categories remained unchanged as they have done for several years: in the EU during reporting period, these were Global Internet portals (16.08%), Online stores (15.73%) and Payment systems (13.67%).
