$6.$ A batch of $73$ time sheets was sent to the payroll department for weekly processing. Somehow, one of the time sheets did not get processed. The mistake was not caught until payday, when one employee complained about not receiving a paycheck.

$7.$ Attackers broke into the company$$s information system through a wireless access point located in one of its trading branches. The wireless access point had been purchased and installed by an office manager without informing central IT or security.

$8.$ To facilitate working from home, an employee installed a modem on his office workstation. An attacker successfully penetrated the company$$s system by dialing into that modem. Again, due to the diligent efforts of Tommy Lew, sensitive customer information was not compromised, according to internal sources.

$9.$ An attacker gained access to the company$$s internal network by installing a wireless access point in a wiring closet located next to the elevators on the fourth floor of a high$-$rise office building that the company shared with seven other companies.

$10.$ A fictitious invoice was received and a check was issued to pay for small supplies that were never ordered or delivered.

$11.$ On the job, Michelle got a call from the local police asking why she was sending a caller multiple adult text messages and sexually explicit emails per day. After further investigation, Michelle$$s account records proved the calls were not coming from her phone or email. Neither she nor her mobile company could explain how the messages were sent. After finding no way to block the unsavory messages, she changed her mobile number and quit STI to avoid further embarrassment by association.
