Analysis Summary
LAPSUS$ data extortion is a new and emerging ransomware and extortion group that has successfully attacked major conglomerate. Like most ransomware groups, LAPSUS$ also infiltrates organizations with a phishing attack. From there on, they exploit vulnerabilities like privilege escalation to get hold of administrative rights and blatantly display their abilities. The City of London Police arrested seven teenagers suspected to be members of the data extortion gang. From those seven, two have been charged.
“Both teenagers have been charged with: three counts of unauthorised access to a computer with intent to impair the reliability of data; one count of fraud by false representation and one count of unauthorised access to a computer with intent to hinder access to data. The 16-year-old has also been charged with one count of causing a computer to perform a function to secure unauthorised access to a program.” – City of London Police
