Ransomware attacks double since 2017, and now target business critical systems
Ransomware attacks are a key cybersecurity threat for global organizations, warns Verizon’s 2018 Data Breach Investigations Report (DBIR). It is the most common type of malware, found in 39 percent of malware-related data breaches – double that of last year’s DBIR, and accounts for over 700 incidents. What’s more, Verizon’s analysis show that attacks are now moving into business critical systems, which encrypt file servers or databases, inflicting more damage and commanding bigger ransom requests.
DBIR analysis also flags a shift in how social attacks, such as financial pretexting and phishing, are used. Attacks such as these, which continue to infiltrate organizations via employees, are now increasingly a departmental issue. Analysis shows that Human Resource (HR) departments across multiple verticals are now being targeted in a bid to extract employee wage and tax data, so criminals can commit tax fraud and divert tax rebates.
“Businesses find it difficult to keep abreast of the threat landscape, and continue to put themselves at risk by not adopting dynamic and proactive security strategies,” says George Fischer, president of Verizon Enterprise Solutions. “Verizon gives businesses data-driven, real-life views on the cyber-threat landscape, not only through the DBIR series but also via our comprehensive range of intelligent security solutions and services. This 11th edition of the DBIR gives in-depth information and analysis on what’s really going on in cybercrime, helping organizations to make intelligent decisions on how best to protect themselves.”
