Read the following passage and choose the best answer to each of the following questions from 23 to 30.

1. A group of teenagers and young adults from the U.S. and the U.K. are among the most common cyber attackers today, according to Charles Carmakal, the CTO of Mandiant Consulting. He shared this information during a media briefing at the RSA Conference. They typically speak English as their first language and are very skilled at tricking people, also known as social engineering.

2. These young hackers were responsible for some of the biggest cyber attacks last year, including breaches at companies like Twilio, Uber, and Okta. The attack on Twilio affected at least 163 other victims, making the damage even worse. Carmakal said, "We've seen very young individuals break into some of the biggest organizations by leveraging these techniques that are so hard to defend against."

3. These attackers use personalized tricks to convince people to visit harmful websites and share sensitive information, like passwords and multi-factor authentication codes. Carmakal explained, "It's all traversing through the cellular network so enterprises aren't able to even monitor this and detect it," making it harder for companies to protect themselves.

4. Groups like Oktapus and Lapsus$ are known for using threats and harassment in their attacks. They target not only companies but also the families of employees. Carmakal shared, "It's a very different story if you're an executive of the company, and your daughter is being harassed by a threat actor." These personal attacks often make it more likely for victims to pay the ransom, as Carmakal said, "Your desire to pay or your willingness to pay shoots up tenfold when you're dealing with personal attacks."

A.

B.

Their attacks extend beyond businesses, reaching the employee's relatives as well.

C.

The families of their employees suffer greatly as a result of the businesses they attack.
