The extensive the greater part (80%) of ransomware attacks can be traced again to frequent configuration glitches in computer software and units, according to Microsoft.
The tech giant’s most recent Cyber Indicators report focuses on the ransomware as a service (RaaS) model, which it statements has democratized the skill to launch attacks to groups “without sophistication or highly developed expertise.”
Some RaaS packages now have over 50 affiliate teams on their books, Microsoft claimed.

For defenders, a important challenge is making certain they really don’t depart programs misconfigured, it additional.
“Ransomware attacks require decisions based on configurations of networks and vary for every single victim even if the ransomware payload is the similar,” the report argued.
“Ransomware culminates an attack that can include things like information exfiltration and other affect. Mainly because of the interconnected nature of the cyber-criminal financial system, seemingly unrelated intrusions can develop upon each other.”
Though every single attack is diverse, Microsoft pointed to lacking or misconfigured security items and legacy configurations in business applications as two vital parts of risk publicity.
“Like smoke alarms, security products need to be set up in the correct areas and examined frequently. Validate that security resources are functioning in their most secure configuration, and that no part of a network is unprotected,” it urged.
“Consider deleting duplicative or unused apps to do away with risky, unused products and services. Be aware of exactly where you allow distant helpdesk apps like TeamViewer. These are notoriously qualified by menace actors to attain express accessibility to laptops.”
Despite the fact that not named in the report, a different process consistently misconfigured and hijacked by ransomware actors is the remote desktop protocol (RDP), which typically is not shielded by a strong password or two-factor authentication. It’s greatly believed to be 1 of the top rated 3 vectors for attack.
The negative information for network defenders is they never have a great deal time following initial compromise to include an attack. Microsoft claimed the median time for an attacker to commence relocating laterally inside of the network following device compromise is 1 hour, 42 minutes.
The median time for an attacker to entry personal data subsequent a phishing email is one hour, 12 minutes, the business added.
Amid Microsoft’s tips for mitigating the ransomware risk are:
- Greatly enhance credential cleanliness
- Audit credential exposure
- Decrease the attack area
- Harden the cloud
- Prevent security blind spots
- Cease initial access
