A longstanding risk actor affiliated with Hamas has been conducting espionage towards governments throughout the Center East and damaging wiper assaults in Israel.
“Wirte” is a 6 1/2-year-old superior persistent risk (APT) working to help Hamas’ political agenda. Examine Level Analysis identifies it as a subgroup of the Gaza Cybergang (aka Molerats), which can be thought to overlap with TA402.
In current weeks and months, Wirte has leveraged the Gaza conflict to unfold phishing assaults towards authorities entities unfold throughout the area. It has additionally been finishing up wiper assaults in Israel. “It exhibits that Hamas nonetheless has cyber capabilities, even with the continued conflict,” says Sergey Shykevich, risk intelligence group supervisor at Examine Level.
Wirte’s Spying and Wiping Assaults
Wirte assaults are usually not notably distinctive or refined. A PDF in an e mail would possibly include a hyperlink directing targets to a file for obtain, named indirectly to lend it legitimacy (e.g., “Beirut — Developments of the Conflict in Lebanon 2”). The file will include a lure doc, a number of official executables, and the malware.
To improve this an infection chain, Wirte has typically made use of the IronWind loader, beginning in October 2023. IronWind makes use of a posh, multistage an infection chain to drop malware, with the objective of irritating evaluation. It employs geofencing, and reflective loaders that run code straight in reminiscence, relatively than on the disk, the place it’d in any other case be noticed by antivirus software program.
In an espionage-focused assault, the top of this chain would possibly deliver the open supply penetration testing framework “Havoc.” Havoc permits persistent entry to a compromised machine, helpful for establishing distant management, performing lateral motion, stealing knowledge, and extra.
In February and October 2024, in contrast, Wirte campaigns climaxed with the deployment of a wiper known as “SameCoin.”
Final month, Wirte puppetted the e-mail deal with of a official Israeli reseller of ESET software program. Its lure message — despatched to hospitals, municipal governments, and others — warned recipients that “Authorities-based attackers could also be attempting to compromise your system!” and included a obtain hyperlink. The hyperlink first tried to hook up with the web site for Israel’s Residence Entrance Command, a wing of the Israel Protection Forces (IDF) accountable for defending civilians. Its web site is accessible solely to these inside Israel, so if the redirection succeeded, the assault would proceed.
Subsequent, a downloaded zip file dropped and decrypted a pro-Hamas wallpaper JPG, a propaganda video, a software designed to allow lateral motion inside focused networks, and the SameCoin wiper.

What Wirte Needs
Wirte spying has crossed into Egypt and Saudi Arabia, however its favored targets look like from Jordan and the Palestinian Authority (PA), the federal government entity that oversees elements of the West Financial institution and is managed by Fatah, Hamas’s major political rival inside Palestine. For essentially the most half, this has remained constant in its half-dozen-year historical past.
Wirte has developed considerably is in its method to Israel. And on this manner, it has additionally mirrored different Palestinian risk actors.
“Earlier than the conflict, it was centered totally on espionage, and stealthy persistence in networks,” Shykevich explains. That is in stark distinction to its newest wave of loud wiper assaults, for instance, which have been timed to start on Oct. 7, the one-year anniversary of Hamas’s Operation Al-Aqsa Flood, the fear assault that killed greater than 1,000 Israelis and led to the seize of almost 250 extra.
“Now, it has change into an increasing number of about making [breaches] public, exhibiting the info, the destruction. The main target is an increasing number of on hack-and-leak operations, and the way they’ll use cyber capabilities to attempt to form a story.”
