4、 PC Risk Report 2021 It has been more than a year since Covid-19 started spreading and, in that time, the virus has defined the entire world, both online and offline. Avast observed cybercriminals using the pandemic to their advantage, spreading scams and phishing attacks to exploit peoples natural

5、thirst for information during unprecedented times. During this time, ransomware attacks continued to thrive, especially targeting medical institutions and critical infrastructure. Certain types of mobile threats, including stalkerware and adware, flourished due to people being forced into lockdown a

6、nd likely spending more time on their smartphones and tablets. It seems like cybercriminals specifically targeted the most vulnerable groups of our society, some of whom were forced to use online tools and services for the first time. Cybercriminals began to promote mobile adware more heavily to you

7、nger audiences via popular social platforms, and performed ruthless technical support scams targeting the elders and the less digitally savvy. This PC Risk Report takes a snapshot of 30 days in the first half of 2021 vs. the same time period in 2020, and specifically looks at Windows-threats targeti

8、ng home and business users. It reveals that the pandemic did not slow down cybercriminals as, globally, online threats still increased year over year. Home users have a 29.39% chance of encountering any type of malware, which represents an increase of around 5% compared to the same timeframe the pre

9、vious year (28.08%). Business users have a 13.9% chance of encountering malware; this number has increased by almost 24% compared to the previous year (11.25%). Businesses generally often have more layers of protection in place than home users, making them a bit less prone to encountering malware. N

10、onetheless, enabling the workforce to work from home has posed serious challenges to business security and this can be seen in the increased risk ratio. With hundreds of millions of users worldwide, Avast has one of the largest threat detection networks in the cybersecurity industry. The attacks on

11、these devices provide valuable insights and knowledge of the most prevalent threats and those who have been most affected by them. This report provides an overview of cyberattacks that happened within one month, giving a picture in time of the general risk users and businesses face globally and in d

12、ifferent countries. Cyber threats are not all the same, but for this report, we group the threats into two high level categories: simple threats and advanced threats.4 ContentsIntroductionAAvast Global PC Risk Report 2021 Simple ThreatsSimple threats are malware, often produced by script kiddies, th

13、at do not contain advanced packers, anti-emulation features, and other types of self protection. These threats tend to use tried and tested methods to scam users or infect their devices, such as viruses, trojans, phishing or sextortion scams and spyware. These attacks aim to reach as many people as

14、possible, to maximize return for cybercriminals.Advanced ThreatsAdvanced threats include malware spread by nation states, malware with custom packers and hardcore anti-emulation features. These often come from criminal groups that focus on successful infection rates, making sure that the malware the

15、y create circumvents most security solutions users have in place. We define these more sophisticated threats as advanced threats. Advanced threats are new, not yet before seen threats, designed to bypass common protection technologies included in security software, such as signatures, heuristics, em

16、ulators, URL filtering, mail scanning, etc. APT campaigns such as the one targeting governmental agencies in East Asia and the many ransomware attacks which made the headlines the past year, are some examples of this type of threat. In most cases, these advanced threats are freshly new, tested to ma

17、ke sure they are not detected when scanned by an antivirus.MethodologyThe data included in this report is collected from Avasts threat detection network, and represents a data snapshot, constructed with the threats Avast protected its PC users from during March 16, 2021 and April 14, 2021. In order

18、to provide statistically relevant data, this report includes data from countries, territories and regions with a sample size of at least 10,000 computers belonging to home users that encountered threats during the month we collected the data, and at least 1,000 computers used by businesses. The data

19、 looks at total threats and advanced threats, evaluating the risk ratio for home and business users around the world. To calculate the risk ratios for this report, we divided the number of computers where Avasts protection layers stopped at least one threat, by the total number of computers Avast ac

20、tively protected within the 30-day period. When comparisons to the previous year were made, this refers to data from the exact same period of time, March 16, 2020 to April 14, 2020.Global Risk RatioBAvast Global PC Risk Report 2021 According to our data, the worldwide chance of infection from any ty

21、pe of malware - this includes simple and advanced threats - for a business computer is 13.9% (11.25% in the previous year). For home users, on the other hand, the risk of encountering any type of malware is double, with a 29.39% chance of infection (28.08% in the previous year). The chances of users

22、 being targeted by an advanced threat are lower, but the proportion is similar to all threats, with consumers having a 5% chance of encountering an advanced threat (4.61% in the previous year) and businesses having a 2.29% chance (1.98% in the previous year).Global Home User Risk Ratio: All Threats6

36、vast Global PC Risk Report 2021 There has been an increase in the risk ratio from both types of users and both types of threats. With the pandemic, home users started to spend more time at home and had to rely more prominently on their devices to connect with the outside world in ways they didnt nee

37、d to before - staying in touch with their loved ones, studying, enjoying entertainment, and doing fitness workouts. Some less tech-savvy users were for the first time introduced to, for example, virtual meeting tools, online banking, online streaming and online shopping. With screen time increasing,

38、 so has the exposure to threats and the chances of falling victim to them grown.In general, home users are at higher risk of encountering threats, as they are typically solely responsible for protecting their computers. Additionally, home users interact with different content than business users. Cy

39、bercriminals create threats that take advantage of the activities carried out by home users, regardless of age, and exploit their potential lack of cybersecurity awareness and cautiousness. The majority of computer users, whether it be business or home users, are often blindly attacked, meaning they

40、 arent specifically targeted with personalized attacks.Nonetheless, what we can say is that most cybercrime is money driven, and thats one of the main factors cybercriminals consider when choosing victims. With that in mind, it would be logical to think that most attacks would go after users in coun

41、tries where the population has more buying power, but this sometimes poses some limitations for cybercriminals. For example, developed countries tend to have more robust security practices than others, and have the ability of filtering attacks before they even reach users PCs. Sometimes, cybercrimin

42、als also face language barriers and this can limit the reach or the success of their campaigns. Attackers sometimes also filter out certain user groups in their code, so some wont attack the population from their own country or its allies.The numbers included in this report are average figures and i

43、ts important to remember that correlation is not causation when taking the data included in this report into account. 12 ContentsThe State of Cybersecurity CAvast Global PC Risk Report 2021 Security risk of employees working from homeThe pandemic also forced many companies around the world to send e

44、mployees home to work remotely. Employees took their company devices home which broadened the attack surface for companies. Not every company was prepared to have their employees work from home on such short notice, and not all home networks infrastructure were as secure as enterprise networks, leav

45、ing companies at risk.Businesses, especially larger businesses, often have additional security layers in place, blocking threats before they even enter a business network, set up by dedicated IT teams or external IT administration partners. Businesses usually offer training and education around curr

46、ent threats and also have more restrictive policies in place. When at work, users browsing activities may be more limited and therefore less risky than at home, where they might shop online, take care of their finances, visit video streaming and gaming sites that can potentially harbor risks, withou

47、t the benefit of additional layers of protection they have in their work environment.This, however, doesnt mean businesses, including government agencies, are immune to cyber attacks. Ransomware attacks have become especially prevalent. In the beginning of 2020, Avast saw an increase in ransomware a

48、ttacks in the early pandemic months. Ransomware grew by 20% during March and April in comparison to January and February. And these attacks have continued during the rest of the year and the beginning of 2021. Since the start of the pandemic, the average ransom payment has also continued to climb, u

49、p 43% from the last quarter of 2020 to an average of over US$200,000. Companies like Colonial Pipeline, AXA, Garmin, Jack Daniels, Travelex and the Ritz London were hit with ransomware throughout the past year. Cybercriminals also didnt refrain from attacking hospitals around the world during the pa

50、ndemic.13 ContentsAvast Global PC Risk Report 2021 The State of Cybersecurity CHigher risk ratio in conflict regionsIf we take a look at the countries with the highest risk ratio, both for home users and business users, we can see that geographies with more conflictive socio-political situations see

51、m to be facing more risk in the online world as well (Middle East, Asia, Africa, and Eastern Europe). If we take a look at the top ten safest countries, meaning the ones with the lowest risk ratio, we can find some differences in terms of home users and business users. When looking at the safest cou

52、ntries for home users, we can see that those listed all belong to the OECD (Organisation for Economic Co-operation and Development), in addition to Puerto Rico. This organization is made up of 36 countries that work together to improve the economic and social well-being of people around the world. T

53、hese countries are among the early technology adopters, which means the broad mainstream of users in these countries, for the most part, may be more aware and better informed when it comes to PC security best practices. Even so, this correlation is not completely conclusive. The same is true regardi

54、ng the list of lowest risk countries for all types of threats for business users, in addition to the Dominican Republic. This changes, though, when looking at advanced threats for business users, where the common denominator seems to be the size of the countries. The list combines countries from Nor

55、th America and the Caribbean, Asia Pacific, Western Europe, Central Europe and Eastern Europe, but all ten countries have populations smaller than 11 million citizens. Considering that advanced threats involve sophisticated and complex attacks, these may be targeting bigger businesses or countries w

56、ith big offices or global companies and organizations.14 ContentsAvast Global PC Risk Report 2021 ConclusionDWhat we can conclude is that the pandemic did not slow down cybercriminals. Instead they seized the opportunity of people spending more time online to adapt old tricks to spread various types

57、 of fakes, scams, and to target major businesses with ransomware. Cybercrime today is a professionalized business and threat actors are constantly looking for new and effective ways to attack people around the world. Cybercriminals take advantage of trends, to make sure they attract as many potentia

58、l victims as possible. Both home and business users need protection, regardless of where they find themselves in the world. Cybercrime is a profitable business that is only expected to grow and cybercriminals dont discriminate when it comes to who they target. There is one clear conclusion, the risk

59、 ratio has increased worldwide for all threats, including advanced threats. The number of connected devices is increasing dramatically, and even though this report just focuses on threats encountered by PC users, the fact is that there are more devices that can be used to launch attacks from, as wel
