Cybersecurity researchers have turned the spotlight on a new
wave of offensive cyberattacks targeting Palestinian activists and
entities starting around October 2021 using politically-themed
phishing emails and decoy documents.

The intrusions are part of what Cisco Talos calls a longstanding
espionage and information theft campaign undertaken by the Arid Viper hacking group[1] using a Delphi-based
implant called Micropsia dating all the way back to June 2017[2].

The threat actor’s activities[3], also tracked under the
monikers Desert Falcon and the APT-C-23, were first documented in
February 2015[4]
by Kasperksy and subsequently in 2017, when Qihoo 360 disclosed
details of cross-platform[5]
backdoors[6]
developed by the group to strike Palestinian institutions.

Automatic GitHub Backups

The Russian cybersecurity company-branded Arid Viper the “first
exclusively Arabic APT group.”

Then in April 2021, Meta (formerly Facebook), which pointed out
the group’s affiliations to the cyber arm of Hamas[7], said it took steps to
boot the adversary off its platform for distributing mobile malware[8] against individuals
associated with pro-Fatah groups, the Palestinian government
organizations, military and security personnel, and student groups
within Palestine.

Decoy document containing text on
Palestinian reunification

The raft of new activity relies on the same tactics and document
lures used by the group in 2017 and 2019, suggesting a “certain
level of success” despite a lack of change in their tooling. More
recent decoy files reference themes of Palestinian reunification
and sustainable development in the territory that, when opened,
lead to the installation of Micropsia on compromised machines.

Prevent Data Breaches

The backdoor is designed to give the operators an unusual range
of control over the infected devices, including the ability to
harvest sensitive information and execute commands transmitted from
a remote server, such as capturing screenshots, recording the
current activity log, and downloading additional payloads.

“Arid Viper is a prime example of groups that aren’t very
advanced technologically, however, with specific motivations, are
becoming more dangerous as they evolve over time and test their
tools and procedures on their targets,” researchers Asheer Malhotra
and Vitor Ventura said.

“These [remote access trojans] can be used to establish
long-term access into victim environments and additionally deploy
more malware purposed for espionage and stealing information and
credentials.”
