“Malware” describes any malicious program created to wreak havoc or mischief on a computer system. It’s also an ever-evolving ecosystem thanks to the constant push-and-pull between security professionals and cybercriminals. Shifts in the malware environment change every year, although long-term trends are identifiable in year-over-year data reports.
Despite numerous anti-malware measures, cybercriminals and hackers aren’t ones to give up easily, especially not as long as there’s money to be made in malware. Even still, some traditionally-popular forms of malware appear to be losing favor in 2021 as hackers and cybercriminals change their tactics to attack new or underutilized vulnerabilities.
Signs currently point to hackers shifting their focus more toward discrete infections through IoT and email, with a continued focus on enterprise businesses and governments versus average web users, especially when it comes to ransomware infections.
Here’s a rundown of the most interesting malware statistics:
1. Employees with infected machines are spreading viruses more broadly
In 2019, 71% of organizations experienced malware activity that spread from one employee to another. In 2020, that number fell to 60%, its lowest for the last three years. The decrease in the employee-to-employee spreading of malware could be one of any number of reasons; for instance, organizations may have a better awareness of the techniques attackers use, or perhaps they’ve simply shored up their digital defenses now that so many of us are working from home.
2. Business-disrupting ransomware attacks nearly doubled
In its 2020 State of Email Security Report, Mimecast found that 51% of organizations experienced a ransomware attack that led to at least a partial disruption of business operations. The previous year, 53% of organizations reported experiencing these types of malware attacks, so the number has fallen slightly.
3. Organizations in the US report the largest number of ransomware attacks, followed closely by those in the UK
Organizations worldwide report ransomware attacks impacting business, but it seems businesses in the US and UK have been hit the hardest in the past year, with 55% and 54% of companies impacted, respectively. This is a significant reduction since last year, though, when 62% of American businesses were victim to a ransomware attack. However, in 2019, only 39% of UK businesses report being impacted by ransomware.
4. Over 60% of organizations may have understaffed cybersecurity teams
In its 2020 State of Cybersecurity report, ISACA found that 62% of cybersecurity professionals believe their organization’s cybersecurity team is understaffed. Understaffing among organizations, including business and government, could create a strain on existing staff and lead to an increased risk from malware threats.
Almost half (47%) reported their organizations were “somewhat” understaffed, while 15% reported they were “significantly” understaffed. A further 31% reported that their organization is “appropriately” staffed, while just 3% reported being either “somewhat” or “significantly” overstaffed.
The demand for workers is also increasing year-over-year. From C-suite executives to technical and contributors, jobs across the cybersecurity industry continue to go unfilled at demand outpaces the growth in the number of workers with the requisite skills.
5. Some types of malware are on the decline
A collection of recent data and research points to a change in how consumers and businesses experience and receive malware. The SecureList IT Threat Evolution Report for Q3 of 2020 shows that both miners and ransomware are rarer (reduced by 47% and 31%, respectively) than they were at the same time last year.
6. Traditional malware attack vectors taking a huge hit
The number of websites serving up malware is at its lowest point since 2007, according to Google’s Transparency Report. Instead, consumers are increasingly dealing with phishing websites that seek to glean passwords, credit card numbers, Social Security Numbers, and other private information directly from visitors without requiring any direct malware downloads. In fact, phishing sites have seen an increase of more than 750% since 2007.
Google’s data shows the number of malware sites detected per week continues to fall every year. As of January 2021, Google detected around 600-800 malware-infected sites per week. By contrast, Google was detecting 3000+ malware sites weekly between January and March of 2019, and between 5000-7000+ during that same time period in 2018.
7. Phishing sites are now an incredibly popular attack method
Phishing sites are typically designed to look like the official version of other websites. PayPal is a commonly-mimicked site, for example, as gaining access to users’ PayPal credentials can be distinctly profitable for hackers. Banking and social media sites are also fairly common targets.
8. Google removing far fewer malware-infected sites
According to Google’s Transparency Report, 2.195 million websites made its list of “Sites Deemed Dangerous by Safe Browsing” category, as of January 17, 2021. The vast majority of those (over 2.1 million) were phishing sites. Only 27,000 of Google’s removed sites were delisted because of malware. That’s more than a 800 percent difference in favor of phishing sites, which have seen a year-over-year increase of 28 percent.
9. China remains a malware hotspot with 2% of scanned sites hosting malware
Google’s Safe Browsing tool automatically scans websites across the world to help detect which sites are infected with Malware. As of April 2020, China and Russia were the worst off with 2% of scanned sites hosting malware. Fewer than 1% of scanned sites in the US, UK, and Germany, and Spain were found to contain malware (although Spain did spike to 3% briefly earlier in the year).
10. The number of malware attacks declined for the first time since 2016
The number of new malware attacks declined for the first time since 2015. According to SonicWall’s 2020 Cyber Threat Report, the company detected 9.9 million malware attacks in 2019, compared to 10.5 million in 2018.
11. New malware variants decreasing year-over-year
SonicWall reported almost 10 billion malware attacks took place this past year, which sounds bad but actually represents a small decrease from last year. For contrast, there were 10.5 billion attacks in 2018 and just 8.6 billion in 2017.
12. Domain Generation Algorithms are still hampering malware mitigation efforts
Domain Generation Algorithms, or DGAs, allow malware architects to automatically generate a large number of domain names which then serve as rendevous points to help control and collect data from the active malware infections. DGAs make investigation and analysis efforts difficult, which in turn makes it difficult to shut down botnets.
Over 40 malware families employ DGAs, including well-known malware including CCleaner, Emotet, and Mirai. SonicWall identified over 172 million randomly-generated domains in 2019.
13. Malware attacks on non-standard ports rose, and then fell, in 2019
Sonic Wall’s 2020 report found that attacks on the tens of thousands of non-standard ports available increased to 19% of all attacks in Q2 2019, only to fall down to 11% by Q4 2019. The vast majority of attacks still (and likely will remain) a problem for standard ports, such as HTTP (port 80).
14. Malware and ransomware attacks down, but IoT malware is up
IoT devices are proliferating, and many come with far more limited malware protection than devices operating more common operating systems. In 2019, SonicWall found ransomware was down 9% and malware was down 6%, but IoT malware was up 4.8%.
Still, there were 9.9 billion malware attacks as a whole, with 34.3 million coming against IoT devices.
15. Over 439,000 new malware variants were detected in 2019
SonicWall identified 439,854 “never-seen-before” malware variants. Although less malware was detected in 2019 versus 2018, a larger portion of the malware detected was new variants. There were 12.3% more new variants detected in 2019.

16. PDFs and Microsoft Office files were used in nearly 38% of new malware detections
Their ubiquity across devices makes PDFs and Office files, such as Word and Excel documents, extremely popular as payload mechanisms for malware authors. SonicWall found over 20% of “never-before-seen” malware files were couched in Office files. Over 17% were carried in PDF files.
17. As cryptocurrencies rebounded, so did cryptojacking
Cryptojacking actually fell overall in 2020, but first, it experienced an unprecedented spike in March. Now, you may be tempted to blame the pandemic for this, but as SonicWall observes, there’s usually a spike at around this time; the worldwide lockdowns likely only enhanced the severity of this one.
The chaotic ups and downs in cryptojacking activity highlight just how much cybercriminals respond to market demands. Malware has always been about achieving the best possible outcome (stolen information and money) with the least amount of effort. An increase in the use of website malware blocking technologies is why phishing sites are far more popular, but cryptojacking also makes for an easy money-making venture for cybercriminals who, for all intents and purposes, follow the same principle as Wall Street brokers: “buy low, sell high”.
18. Coinhive’s shutdown revealed its startling contribution to cryptojacking
Although the Coinhive cryptocurrency mining service was legitimate, it was quickly co-opted by cybercriminals who installed it surreptitiously onto websites to collect cryptocurrency revenue.
Originally launched in 2017, Coinhive voluntarily shut down in March 2019. SonicWall found that after the Coinhive shutdown, cryptojacking hits on its cybersecurity monitoring network fell by 78%.
19. Cerber takes the lead in hackers’ favorite ransomware tool
Notably, Cerber is part of what’s known as “Ransomware as a Service” or RaaS. Cybercriminals can hire others to launch attacks using the Cerber malware, and receive around 40 percent of the paid ransom. In 2017, SophosLabs investigated 5 RaaS kits and found that some can be extremely inexpensive (less than $40), while others can exceed several hundred dollars to purchase and employ. However, they’re highly customizable, and hackers appear to operate their ransomware services with a surprising degree of professionalism.
20. The Cerber ransomware family accounted for 33% of all ransomware attacks in 2019
There were over 189 million ransomware signatures detected in 2019. Of that, 77 million were part of the Cerber family. The many different Cerber ransomware variants were responsible for 33% of ransomware attacks last year.
21. 3.7 million malware attacks were sent using encrypted traffic
A growing number of threat actors are sending malware attacks over encrypted SSL/TSL traffic. Encrypted channels make detection and mitigation more difficult, resulting in higher success rates for the malware packages in question. SonicWall detected 3.7 million malware attacks of this nature in 2019, which marked a 27% increase compared to 2018.
22. Symantec’s data confirms malware variant declines
Symantec also recorded a strong decline in malware. The security company found a 61 percent year-over-year decrease in new malware variants between 2017 and 2018. For its part, WatchGuard reported that zero-day malware accounted for over 50 percent of all malware blocked in Q3 2020, an increase of 14% year on year.
23. “Formjacking” is a growing problem for websites
Symantec identified an average of 4,800 websites compromised with formjacking code each month in 2018. The security company also blocked 3.7 million formjacking attacks that year, highlighting the growing threat. There’s little data related to formjacking to draw upon prior to 2018, which helps indicate the rapid growth of this malware attack vector.
Overall, it appears cybercriminals have massively switched their tactics from trying to get web users to download malware directly from infected web pages and instead now prefer alternative malware delivery methods. Even formjacking, which is in effect a type of malware, doesn’t require the user to download a file. Hackers appear to now prefer more discrete methods.
24. The City of Baltimore suffered a major ransomware attack
In May 2019, news reports rolled in covering the Baltimore City government’s painstaking (and embarrassing) efforts to recover from a major ransomware infection. It took Baltimore City’s government 36 days to loosen hackers’ grip on its data, and even longer to fully recover all of the systems that were locked down. The city spent over $18 million recovering from the attack.
Although—to our knowledge—Baltimore did not pay a dime of that money to the hackers who held the city’s files hostage, many ransomware victims do choose to pay instead of eating such high costs associated with recovery.
As with most malware, ransomware isn’t a guaranteed income source for cybercriminals, but it’s far more successful than most traditional malware attempts. As a result, some ransomware avenues are still on the rise in 2019, even as security companies develop more effective mitigation methods and tools.
25. Enterprises are the main target for ransomware
Symantec noted a 12 percent increase in enterprise ransomware in 2018, for example, although it also recorded a 20 percent decline in ransomware overall that year. The company also identified a 33 percent rise in mobile ransomware, which highlights a new trend of criminals targeting mobile users with file-encrypting malware.
Worringly, Postive Technologies found that there’s a growing “access for sale” market on the dark web. In fact, hackers were advertising access to the networks of major US service sector and industrial companies, with some buyers offering up to 30% commission on the proceeds of any hack performed.
26. The “Cerber” ransomware family is leading the rise in ransomware attacks
Other reports show a a 20 percent increase in ransomware attacks in the first half of 2020, and payments doubling on average, with the Cerber family of ransomware identified as the largest group. SonicWall also noted nearly 40 million Cerber hits in the first half of 2019. Comparatively, the volume of Cerber-family ransomware hits soared to over 101 million in 2018. The next closest ransomware family in 2018, BadRabbit, had fewer than 8 million hits the whole year.
27. Ransomware payment demands are increasing in size
One of the biggest reasons hackers appear to prefer ransomware versus more traditional viruses and malware is because of the payoff. Ransomware payments are now totaling around $1 billion per year, making them far more lucrative than traditional malware operations. Ransomware is so financially-viable, in fact, that hackers have upped the amounts they’re asking for in ransom payments. According to Beazley, the criminals’ asking price for ransomware removal increased 93 percent in Q1 2019.
Malware projections for 2021 and beyond
Based on what we’ve seen so far in 2020, we can expect to see a few key takeaways for the remainder of 2021:
- Malware-infected sites will likely continue to fall out of favor and decrease in volume
- Cybercriminals will continue to target larger enterprises with malware in the hopes of securing a large, one-off payment
- The demanded ransomware payment amount will continue to increase
- Formjacking may continue to increase, although security professionals may start paying more attention and stem its growth into 2021
- The cryptojacking threat to IoT devices will grow, in no small part thanks to the growing number of unsecured IoT devices that consumers purchase in ever-increasing numbers
There’s no telling what new threats may emerge, and how the malware landscape may shift. As major security companies have reported in the past, a fair amount of activity tends to increase in Q4 in most years, which is often associated with the holiday shopping season.
As ever, hackers tend to be reactive instead of proactive, going for low hanging fruit whenever possible, or easily-exploited vulnerabilities in systems where they can be found. Their tactics tend to change only when their efforts become unprofitable.
It’s also hard to ignore the ever-present danger posed by state-sponsored malware attacks, which are rarely profit-driven and tend to be politically-motivated. Such attacks will likely increase into 2020 and 2021, with all eyes on China, Russia, and North Korea, and a keen focus toward the US as the 2020 election season rolls in.
