In current weeks and months, Wirte has leveraged the Gaza struggle to unfold phishing assaults in opposition to authorities entities unfold throughout the area. It has additionally been finishing up wiper assaults in Israel. “It reveals that Hamas nonetheless has cyber capabilities, even with the continuing struggle,” says Sergey Shykevich, menace intelligence group supervisor at Verify Level.
Wirte’s Spying and Wiping Assaults
Wirte assaults aren’t notably distinctive or refined. A PDF in an e mail may comprise a hyperlink directing targets to a file for obtain, named ultimately to lend it legitimacy (e.g., “Beirut — Developments of the Struggle in Lebanon 2”). The file will comprise a lure doc, a number of reputable executables, and the malware.
To improve this an infection chain, Wirte has generally made use of the IronWind loader, beginning in October 2023. IronWind makes use of a fancy, multistage an infection chain to drop malware, with the purpose of irritating evaluation. It employs geofencing, and reflective loaders that run code instantly in reminiscence, somewhat than on the disk, the place it would in any other case be noticed by antivirus software program.
In an espionage-focused assault, the tip of this chain may 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 information, and extra.
In February and October 2024, in contrast, Wirte campaigns climaxed with the deployment of a wiper referred to as “SameCoin.”
Final month, Wirte puppetted the e-mail deal with of a reputable 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 gadget!” 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) liable 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 Desires
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 advanced considerably is in its method to Israel. And on this method, it has additionally mirrored different Palestinian menace actors.
“Earlier than the struggle, 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 had 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 turn out to be an increasing number of about making [breaches] public, exhibiting the info, the destruction. The main focus is an increasing number of on hack-and-leak operations, and the way they will use cyber capabilities to attempt to form a story.”
