Sudo is a utility that allows a system administrator to give certain users (or groups of users) the ability to run commands in the context of any other user – including as root – without having to log in with a different profile. Sudo also logs all commands and arguments in a centralized audit trail system, so admins know which user performed which command and in which context.

In September of 2018, a major textbook rental and online tutoring services company Chegg reported it had suffered a data breach affecting the data of 40 million customers. The data involved in this breach includes user’s names, email addresses, passwords, and shipping addresses. This is one of the largest breaches of data affecting college and university students to date. While Chegg took action in 2018 by resetting user passwords on their site, the stolen data is now in the hands of cyber-criminals and it’s possible that students and former students may have used the same or similar passwords for other account logins across other websites.

The hackers made a ransom demand of $5.3 million in bitcoin in order to decrypt their files. City officials attempted to negotiate with the hackers to reduce the ransom amount and to gain more time as they attempted to recover and restore encrypted files.

None of the 22 Texas towns and municipalities that were victims of a massive ransomware attack in mid-August of 2019 paid the $2.5 million ransom demanded of them by the hackers. Texas officials based the decision not to pay largely on public sentiment that tax-payer money should not go to pay hackers. Many people believe paying the ransom incentivizes cyber-criminals to launch more ransomware attacks.

On August 16, 2019, hackers launched a large-scale "coordinated" ransomware attack on 22 towns in Texas. The cyberassault began Friday morning and mainly affected city business and financial operations. Interrupted services include processing utlity payments, issuing permits, as well as birth and death certificates. Officials say this attack is the first of its kind where one individual or hacking group has targeted multiple cities at once. It is being viewed as a wake-up call for small towns in rural areas.
