The three zero-day flaws addressed by Apple on September 21, 2023, had been leveraged as a part of an iPhone exploit chain in an try to ship a adware pressure known as Predator concentrating on former Egyptian member of parliament Ahmed Eltantawy between Might and September 2023.
“The concentrating on came about after Eltantawy publicly acknowledged his plans to run for President within the 2024 Egyptian elections,” the Citizen Lab mentioned, attributing the assault with excessive confidence to the Egyptian authorities owing to it being a recognized buyer of the business spying device.
In response to a joint investigation carried out by the Canadian interdisciplinary laboratory and Google’s Risk Evaluation Group (TAG), the mercenary surveillance device is alleged to have been delivered by way of hyperlinks despatched on SMS and WhatsApp.
“In August and September 2023, Eltantawy’s Vodafone Egypt cell connection was persistently chosen for concentrating on by way of community injection; when Eltantawy visited sure web sites not utilizing HTTPS, a tool put in on the border of Vodafone Egypt’s community routinely redirected him to a malicious web site to contaminate his cellphone with Cytrox’s Predator adware,” the Citizen Lab researchers mentioned.
The exploit chain leveraged a set of three vulnerabilities – CVE-2023-41991, CVE-2023-41992, and CVE-2023-41993 – which might enable a malicious actor to bypass certificates validation, elevate privileges, and obtain distant code execution on focused gadgets upon processing a specifically crafted internet content material.
Predator, made by an organization known as Cytrox, is analogous to NSO Group’s Pegasus, enabling its prospects to surveil targets of curiosity and harvest delicate information from compromised gadgets. A part of a consortium of adware distributors known as the Intellexa Alliance, it was blocklisted by the U.S. authorities in July 2023 for “enabling campaigns of repression and different human rights abuses.”
The exploit, hosted on a website named sec-flare[.]com, is alleged to have been delivered after Eltantawy was redirected to a web site named c.betly[.]me by way of a complicated community injection assault utilizing Sandvine’s PacketLogic middlebox located on a hyperlink between Telecom Egypt and Vodafone Egypt.
“The physique of the vacation spot web site included two iframes, ID ‘if1’ which contained apparently benign bait content material (on this case a hyperlink to an APK file not containing adware) and ID ‘if2’ which was an invisible iframe containing a Predator an infection hyperlink hosted on sec-flare[.]com,” the Citizen Lab mentioned.
Google TAG researcher Maddie Stone characterised it as a case of an adversary-in-the-middle (AitM) assault that takes benefit of a go to to a web site utilizing HTTP (versus HTTPS) to intercept and drive the sufferer to go to a special web site operated by the menace actor.
“Within the case of this marketing campaign, if the goal went to any ‘http’ web site, the attackers injected visitors to silently redirect them to an Intellexa web site, c.betly[.]me,” Stone defined. “If the person was the anticipated focused person, the positioning would then redirect the goal to the exploit server, sec-flare[.]com.”
Eltantawy acquired three SMS messages in September 2021, Might 2023, and September 2023 that masqueraded as safety alerts from WhatsApp urging Eltantawy to click on on a hyperlink to terminate a suspicious login session originating from a purported Home windows machine.
Whereas these hyperlinks do not match the fingerprint of the aforementioned area, the investigation revealed that the Predator adware was put in on the machine roughly 2 minutes and 30 seconds after Eltantawy learn the message despatched in September 2021.

He additionally acquired two WhatsApp messages on June 24, 2023, and July 12, 2023, through which a person claiming to be working for the Worldwide Federation for Human Rights (FIDH) solicited his opinion on an article that pointed to the web site sec-flare[.]com. The messages had been left unread.
Google TAG mentioned it additionally detected an exploit chain that weaponized a distant code execution flaw within the Chrome internet browser (CVE-2023-4762) to ship Predator on Android gadgets utilizing two strategies: the AitM injection and by way of one-time hyperlinks despatched on to the goal.
CVE-2023-4762, a sort confusion vulnerability within the V8 engine, was anonymously reported on August 16, 2023, and patched by Google on September 5, 2023, though the web big assesses that Cytrox/Intellexa might have used this vulnerability as a zero-day.
In response to a quick description on the Nationwide Vulnerability Database (NVD), CVE-2023-4762 considerations a “sort confusion in V8 in Google Chrome previous to 116.0.5845.179 [that] allowed a distant attacker to execute arbitrary code by way of a crafted HTML web page.”
The most recent findings, in addition to highlighting the abuse of surveillance instruments to focus on the civil society, underscores the blindspots within the telecom ecosystem that may very well be exploited to intercept community visitors and inject malware into targets’ gadgets.
“Though nice strides have been made in recent times to ‘encrypt the net,’ customers nonetheless often go to web sites with out HTTPS, and a single non-HTTPS web site go to may end up in adware an infection,” the Citizen Lab mentioned.
Customers who’re liable to adware threats due to “who they’re or what they do” are really helpful to maintain their gadgets up-to-date and allow Lockdown Mode on iPhones, iPads, and Macs to stave off such dangers.
