Between July and October, Acronis found that the proportion of phishing attacks has risen by 1.3x, accounting for 76% of all attacks – an 18% increase earlier this year.
Phishing and the use of MFA (Multi-Factor Authentication) fatigue attacks, an extremely effective method used in high-profile breaches, are on the rise. Threats from phishing and malicious emails have increased by 60%, and the average cost of a data breach is expected to reach $5 million by next year, according to a recent report on latest cyberthreats and trends report for the second half of 2022 by Cyber protection solution provider Acronis.
The research team who authored the report also saw social engineering attacks jump in the last four months, accounting for 3% of all attacks. Leaked or stolen credentials, which allow attackers to easily execute cyberattacks and ransomware campaigns, were the cause of almost half of all reported breaches in the first half of 2022.
Highlights: Threat landscape sees new challenges
As security tactics and the technologies associated with them evolve, so do the threat actors trying to break into organizations and their ecosystems. The constant feed of ransomware, phishing and unpatched vulnerabilities demonstrates how crucial it is for businesses to reevaluate their security strategies.
Ransomware continues to be the top threat
- Ransomware threats to businesses including government, healthcare, education and other sectors is generally getting worse
- Each month in the second half of this year, ransomware gangs added 200-300 new victims to their combined list.
- The market of ransomware operators was dominated by 4-5 players. By the end of Q3, the total number of compromised targets published for the main operators in 2022 were as follows:
- LockBit - 1157
- Hive - 192
- BlackCat - 177
- Black Basta - 89
- There were 576 publicly-mentioned ransomware compromises in Q3, a slight increase from Q2. The overall number of ransomware incidents decreased slightly in Q3, following a summer high from July to August when Acronis observed a 49% increase in blocked ransomware attacks globally but was then followed by a decrease of 12.9% in September and 4.1% in October.
- As the main threat actors are continuing to professionalize their operations, Acronis notes a shift towards more data exfiltration with most of the large players expanding their targets to MacOS and Linux systems, and consideration of cloud environments.
Phishing and malicious emails remain highly successful for threat actors
- Between July and October 2022, the proportion of phishing attacks rose by 1.3x against malware attacks reaching 76% of all email attacks (up from 58% in H1'2022).
- Spam rates increased by over 15% — reaching 30.6% of all inbound traffic.
- The United States led as the country with the most clients experiencing malware detections at 22.1% in October 2022, followed by Germany with 8.8% and Brazil with 7.8%. These numbers represented a small increase for the US and Germany, especially in financial trojans.
- South Korea, Jordan, and China ranked as the most attacked countries in terms of malware per user in Q3.
- Analyzing the 50 most email-borne-attacked organizations revealed the top targeted industries including:
- Real estate
- Professional Services (Computers & IT)
During this period, an average 7.7% of all endpoints tried to access malicious URLs in Q3 2022, a small reduction from 8.3% in Q2 2022.
Malicious actors continue to seek out and target unpatched systems
While software vendors release patches regularly or often, it is still not enough. Many attacks succeed due to unpatched vulnerabilities.
New zero-day vulnerabilities and old unpatched ones are the top vector of attack to compromise systems.
- A phishing campaign targeted Microsoft users in September by using the news coverage of the passing of Queen Elizabeth II and impersonating "the Microsoft team" to bait recipients into adding memo text onto an online memorial board in September.
- Another large-scale phishing campaign was spotted targeting Microsoft M365 email service credentials, specifically at fin-tech, lending, accounting, insurance, and Federal Credit Union organizations in the US, UK, New Zealand, and Australia.
