This year, there were some reports that social activists, journalists, and politicians were being spied through spyware named Pegasus. This spyware was prepared by the Israeli company NSO Group. Pegasus spyware is used to hack smartphones, including the iPhone. After these reports came to the fore, the US has banned companies from working with the NSO group. Apart from this, Google has also sued NSO. This assignment 1 helps me know and reflect on what I understand about the introduction of statistics. Now the US company Google has explained how Pegasus used to attack the iPhone.
Google has explained that NSO works on zero-click exploration technology through a blog post. The hacker does not send any phishing messages or suspicious links in a zero-click attack. Instead, it works peacefully in the background. Google’s Project Zero team, which analyzes cyber security threats, said, “Protecting zero-click exploits is nothing less than not using the device. It is a weapon against which there is no protection.’ Google said about the iPhone that here Pegasus starts with the message. If the attacker has an Apple ID username or phone number, they can target the user.
Fake gif prop
A user who is a victim of hacking can get a GIF file, but in reality, it is not a GIF file. Then even if .gif is written at the end of it. Hackers can target users by using fake GIFs. According to Google, Apple has completely removed the GIF code path in iOS 15, leading to such attacks.
Use of compression
There are no longer issues with bandwidth or storage as before. The compression used in the 90s continues to be used today. Google says that the JBIG2 image codec compressed images in the 90s, where pixels could only be black or white. Many PDF files were likely to contain the JBIG2 stream in PDF a few years back. Many such old algorithms continue to be used today, used for attacks such as Pegasus.
