Apple :
has
released two critical security updates for four of its core products in
response to a flaw that would have allowed the Pegasus spyware to infect a
device. On Thursday, the last-minute bug fixes were rolled out for the iPhone,
iPad, Apple Watch, and Mac just days ahead of Apple's 2023 launch event on
September 12.
The vulnerability
was
discovered and reported to Apple by The Citizen Lab, an academic research lab
that analyzes security threats and other risks.
Credited
by Apple for the discovery:
the lab issued a report in which it described the flaw as an exploit
chain, that it dubbed Blastpass, capable of compromising iPhones running the
latest version of iOS (16.6) without any interaction from the user. The bug
could be exploited by an attacker sending PassKit attachments
with malicious images via Apple's iMessage.
In
response to the vulnerability, Apple issued two separate fixes for the iPhone
and iPad labeled CVE-2023-41064 and CVE-2023-41061. The Citizen Lab urged all
users to apply the fixes immediately via the latest updates to affected
devices.
For iPhone and iPad users:
iOS 16.6.1 and iPadOS 16.6.1 are
now available to be installed on the iPhone 8 and later, all models of the iPad
Pro, the iPad Air 3rd generation and later, the iPad 5th generation and later,
and the iPad mini 5th generation and later. Head to Settings > General >
Software Update. Tap Download and Install to apply the update.
Fixes
for other Apple devices are available as well.
For
Apple Watch wearers:
WatchOS 9.6.2 is
now waiting to be installed on the Apple Watch Series 4 and later. Open the
Watch app on your iPhone, go to General and then Software Update, and then tap
Download and Install.
And
for Mac users, MacOS Ventura 13.5.2 is ready. For this one, click the
Apple icon and select System Settings. Click General and then Software Update.
Click the button to install the update.
In
its report, The Citizen Lab revealed how it found the vulnerability: "Last
week, while checking the device of an individual employed by a Washington
DC-based civil society organization with international offices, Citizen Lab
found an actively exploited zero-click vulnerability being used to deliver NSO
Group's Pegasus mercenary spyware."
A
spyware tool used by Israel-based NSO Group, Pegasus has gained a level of
infamy for targeting government officials, political activists, and
journalists. The software works by remotely accessing a device to collect
handset data, monitor conversations through messaging apps such as WhatsApp and
Facebook, snoop on email exchanges and browser activity, and spy on people
through a device's camera and microphone.
The
NSO Group has continually maintained that Pegasus is used for legitimate
purposes by governments to track criminal and terrorist activity and monitor
local and global threats. But The Citizen Lab, Amnesty International, and other
groups claim that the spyware is used to target innocent people.
Potential
victims of Pegasus who believe they're being actively targeted are urged to put
their iPhones or iPads into Lockdown Mode. An option available to all
users, Lockdown Mode disables
or limits key features and settings on a device to prevent spyware and malware
from capturing sensitive data.
Pushing
out updates just days in advance of a launch event is rare for Apple, which
speaks to the critical nature of the vulnerability and the need to apply these
fixes.
Next
Tuesday, September 12, Apple is expected to raise the curtain on its new iPhone,
Apple Watch, AirPods, and potentially other products. Along with the new products
will be brand new versions of iOS/iPadOS, watchOS, macOS, and tvOS. Apple
typically releases new versions of its respective operating systems about a
week after the launch event, so expect them around September 19.
