The LockBit 3.0 ransomware variant is arguably the most threatening ofmalware in recent times. With no regard for a victim's industry, the ransomwarehas undergone several evolutions to arrive at an adaptable and evasive variantwhich has been a menace to governments and organisations, recently infiltratingAdvanced Computer Software group. Previous LockBit studies mostly concentratedon measuring the impact of the ransomware attack, prevention, encryptiondetection, decryption, or data recovery, thereby providing little or no benefitto the less tech savvy populace as a detailed breakdown of the mode of attackis rarely examined. This article analyses the LockBit 3.0 attack techniqueswith a contextual illustration of the attack on Advanced Computer Softwaregroup. With the NHS being a major client of the organisation, and its servicesalongside 15 other clients being crippled for hours during the attack,attention is drawn to how dreadful such disruption may be in criticalorganisations. We observed that the upgrade of Lockbit based on releasing newerversions is in a bid to continuously ensure the malware's efficiency - a virtuethat keeps it at the zenith - by staying ahead of improved defenses. Our studyhighlights social engineering as a vibrant portal to Lockbit's maliciousnessand indicates an investment in detection systems may profit more than inprevention systems. Therefore, further research should consider improvingdetection systems against Lockbit 3.0.
