The variety of tried ransomware assaults on Microsoft clients globally have grown dramatically within the final yr, in keeping with Microsoft’s Digital Protection report, launched on Oct. 15. Nevertheless, developments in computerized assault disruption applied sciences have led to fewer of those assaults reaching the encryption stage.
Microsoft reported 600 million cybercriminal and nation-state assaults occurring each day. Whereas ransomware makes an attempt elevated by 2.75 instances, profitable assaults involving knowledge encryption and ransom calls for dropped by three-fold.
Important assault varieties embody deepfakes, e-commerce theft
Microsoft says it “tracks greater than 1,500 distinctive menace teams — together with greater than 600 nation-state menace actor teams, 300 cybercrime teams, 200 affect operations teams, and a whole lot of others.” The highest 5 ransomware households — Akira, Lockbit, Play, Blackcat, and Basta — accounted for 51% of documented assaults.
Based on the report, attackers most frequently exploit social engineering, id compromises, and vulnerabilities in public-facing functions or unpatched working techniques. As soon as inside, they usually set up distant monitoring instruments or tamper with safety merchandise. Notably, 70% of profitable assaults concerned distant encryption, and 92% focused unmanaged units.
Different main varieties of assaults included:
- Infrastructure assaults.
- Cyber-enabled monetary fraud.
- Assaults on e-commerce areas, the place bank card transactions don’t require the cardboard to be bodily current.
- Impersonation.
- Deepfakes.
- Account takeover.
- Id and social engineering assaults — most (99%) of which have been password theft assaults.
- SIM swapping.
- Assist desk social engineering, the place attackers impersonate clients to reset passwords or join new units.
- Credential phishing, significantly by phishing-as-a-service initiatives. Usually these are triggered by HTML or PDF attachments containing malicious URLs.
- DDoS assaults, which brought about a world outage earlier this yr.
Antivirus tampering was additionally a significant participant within the earlier yr: Over 176,000 incidents Microsoft Defender XDR detected in 2024 concerned tampering with safety settings.

Nation-state, financially motivated actors share techniques
Each financially-motivated menace actors and nation-state actors more and more use the identical data stealers and command-and-control frameworks, Microsoft discovered. Apparently, financially-motivated actors now launch cloud id compromise assaults — a tactic beforehand related to nation-state attackers.
“This yr, state-affiliated menace actors more and more used prison instruments and techniques — and even criminals themselves — to advance their pursuits, blurring the strains between nation-state backed malign exercise and cybercriminal exercise,” the report acknowledged.
Microsoft tracks main menace actor teams from Russia, China, Iran, and North Korea. These nation-states could both leverage monetary menace actors for revenue or flip a blind eye to their actions inside their borders.
Based on Tom Burt, Microsoft’s company vice chairman of buyer safety and belief, the ransomware subject highlights the connection between nation-state actions and financially motivated cybercrime. This downside is exacerbated by international locations that both exploit these operations for revenue or fail to take motion towards cybercrime inside their borders.
Skilled Evan Dornbush, former NSA cybersecurity professional, provides views on the matter:
“This report alerts one development presently getting little consideration and more likely to outline the way forward for cyber: the amount of cash criminals can earn,” he stated in an e mail to TechRepublic. “Per the Microsoft report, authorities, as a sector, solely makes up 12% of the aggressors’ concentrating on units. The overwhelming majority of victims are within the non-public sector.”
The sectors most focused by nation-state menace actors this yr have been:
- IT.
- Training .
- Authorities.
- Assume tanks and NGOs.
- Transportation.
Each attackers and defenders use generative AI
Generative AI introduces a brand new set of questions. Microsoft recommends limiting generative AI’s entry to delicate knowledge and guaranteeing that knowledge governance insurance policies are utilized to its use. The report outlines AI’s important impacts on cybersecurity:
- Each attackers and defenders more and more use AI instruments.
- Nation-state actors can generate misleading audio and video with AI.
- AI spear phishing, résumé swarming, and deepfakes are actually widespread.
- Typical strategies of limiting overseas affect operations could not work.
- AI insurance policies and rules can mitigate some threat related to the usage of AI instruments.
- Though many governments agree on a necessity for safety as an vital issue within the improvement of AI, totally different governments pursue it in several methods.
“The sheer quantity of assaults have to be decreased by efficient deterrence,” Burt defined, “and whereas the trade should do extra to disclaim the efforts of attackers by way of higher cybersecurity, this must be paired with authorities motion to impose penalties that additional discourage essentially the most dangerous cyberattacks.”
How organizations can stop widespread cyberattacks
The Microsoft report accommodates actions organizations can take to forestall particular varieties of assaults. TechRepublic distilled some actionable insights that apply throughout the board:
- Disrupt assaults on the method layer, which suggests implementing insurance policies corresponding to for multi-factor authentication and assault floor discount.
- Equally, use “secure-by-default” settings, which make multi-factor authentication necessary.
- Use sturdy password safety.
- Check pre-configured safety settings, corresponding to safety defaults or managed Conditional Entry insurance policies, in report-only mode to grasp their potential affect earlier than going stay.
- Classify and label delicate knowledge, and have DLP, knowledge lifecycle, and Conditional Entry insurance policies round high-risk knowledge and high-risk customers.
Microsoft put its Safe Future Initiative in place this yr, after the Chinese language intrusion into Microsoft authorities e mail accounts in July 2023.
