Internet Threat Rating: The Most Active Malware in 2021

Ranking of the most common cyber threats in 2021

ESET, a leader in information security, presents a ranking of the most common cyber threats in 2021. In particular, according to ESET telemetry, the tactics of extortion programs have become more aggressive, and the number of attacks by selecting passwords and phishing emails has increased.

In addition, ESET found DevilsTongue spyware targeting activists and journalists, as well as new activity by Gamaredon and APT Dukes in Europe. The latter has spread phishing messages to diplomats, think tanks, and international organizations in at least 12 countries.

Extortion programs

Such threats have often made headlines in recent times, attacking critical infrastructure and large IT vendors. The level of detection of this malware remained stable with several periods of significant growth.

In particular, in the last 4 months, three main waves of the spread of extortion programs have been recorded. These included an attack that shut down Colonial Pipeline, the largest pipeline company in the United States, and an attack on a supply chain using a vulnerability in the Kaseya VSA software.

In both cases, the attackers targeted financial gain, not cyber espionage. In particular, the cybercriminals who attacked Kaseya demanded a ransom of $70 million, which is the highest known to date.

The tactics of extortionist programs have become more aggressive. This led to the involvement of law enforcement agencies, which in turn exposed several groups. However, the same cannot be said of TrickBot, whose number of detected samples has doubled since last year’s disposal.

Threats to information theft

The number of such threats increased by 15.7%. Such growth is quite predictable because, in the age of the Internet, information is a commodity that can easily be monetized by attackers. Among the 10 most common threats in this category were spyware, which took the first 6 places in the list, and backdoors, which took the next 4 steps.

Although banking malware is not in the top ten most common this time, the number of detected samples of this type has also increased.

Threats that spread through e-mail

The number of harmful e-mails also increased during the analyzed period. Among them were mostly phishing and fraudulent reports. E-mail threats peaked in the second half of August 2021, with the most common threat being the DOC/Fraud Trojan. This threat was mainly spread through e-mails in which fraudsters blackmailed recipients with videos of adult content.

The Microsoft brand was most often used in phishing emails. Attackers also often impersonated the DocuSign electronic signature service and the WeTransfer file sharing service, indicating in a letter that they were sending documents to the recipient for download.

Fake payment requests, followed by counterfeit banking communications and delivery of goods, continued to be the most common topic in malicious emails.

At the same time, the topic of COVID-19 was also used in spam emails, and fraudsters pretended to be government agencies and health care organizations to force recipients to share confidential information.

Threats to macOS and iOS

In 2021 the level of threat detection for macOS increased by almost 10%. This is due to an increase in the number of detected Trojans by almost half compared to the previous period. Their activity even outpaced the potentially unwanted programs (PUAs) that previously predominated among the threats to macOS.

The largest number of detected samples fell on the program OSX/Mackeeper PUA, which displays unwanted advertising. It is worth noting that this malware is the first in the ranking of threats to macOS for the second year in a row.

Threats to Android

The activity of such threats increased by almost 33% due to the growing proliferation of spyware, advertising, and banking malware. In particular, the activity of the latter species continued to grow since the beginning of the year, increasing by almost half between May and August.

In addition, the activity of malicious applications for cyberbullying has increased. During the analysis of 86 programs with such functionality, ESET specialists revealed numerous vulnerabilities that could endanger not only the data of the victims but also the spies themselves.

Top 4 Best Antivirus for Windows in 2020

Top 4 Best Antiviruses for Windows in 2020

It is worth noting that all antivirus programs in this list are completely free and, above all, safe. The list of the best antivirus programs changes regularly, as developers change and improve something every time, and sometimes completely refuse to provide services for free.

It should be noted that all of these antiviruses have paid versions. We did not consider them. The selection includes only free solutions without time limits. In other words, selected antivirus that does not ask for payment after a few weeks or months of use.

Avira Free Antivirus

Avira Free Antivirus is a comprehensive solution for protecting your computer from any malware. The complex checks not only files, but also potentially dangerous Internet connections, and thanks to the extension for popular browsers – even malicious websites.

The best part is that Avira doesn’t put a lot of strain on your computer. After installing a full set of security, the computer does not begin to spend 90% of its resources to support the life of the antivirus, which is especially important for owners of budget computers and laptops.

AVG AntiVirus Free

AVG AntiVirus Free is an excellent antivirus, the developers of which have made the main bet on protection against phishing. And this is very commendable. Despite the increase in computer literacy, more and more Internet users are becoming victims of phishing attacks. By installing AVG, you will most likely protect yourself from scammers.

However, both regular viruses and Trojans are successfully detected by the antivirus – the database is updated regularly. The only downside to AVG is the forced installation of the extension for the AVG SafePrice browser. If you are installing AVG, be sure to keep this in mind and remove the extension if necessary.

Panda Free Antivirus

Panda Free Antivirus is very different from most other antivirus programs. First of all, the interface. Here it is unusual but attractive and easy to use.

Panda has a built-in free VPN – a trifle, but nice. But the main thing, Panda has a special emergency mode. It is activated if the computer has been affected by viruses or by the user and has stopped turning on. In this case, the antivirus allows you to perform a recovery.

Avast Free Antivirus

One of the best free antivirus Avast is not going through the best of times. This is largely due to the fact that the antivirus has become frequent and intrusive to request the transition to the paid version. Of course, not everyone likes it.

However, like an antivirus, Avast is still good and as easy to use as possible. The user only needs to give permission to conduct intelligent scanning once in a certain period of time and that’s it. Then Avast will figure it out itself, including it will automatically and quietly check files for potential threats in real-time. Another plus of Avast is a large number of additional features.

Rootkits are serious risks simply because they function in the cheapest quantity of a operating-system, causing them to be tough to identify. For instance, some rootkits hook the file system motorists to cover malicious files.

Others even operate outdoors the OS, providing them with a lot more treatments for machine. They are known as bootkits simply because they infect a partition’s Master Boot Record (MBR) and, based on Avast, they have the effect of 62 percent of rootkit infections.

The very best MBR rootkit family is called Alureon, TDL or TDSS. The most recent variant, TDL4, is capable of doing self-propagation and may infect 64-bit versions of Home windows Vista and Home windows 7.
