A longstanding menace actor affiliated with Hamas has been conducting espionage in opposition to governments throughout the Center East and harmful wiper assaults in Israel.
“Wirte” is a 6 1/2-year-old superior persistent menace (APT) working to help Hamas’ political agenda. Examine Level Analysis identifies it as a subgroup of the Gaza Cybergang (aka Molerats), which can also be thought to overlap with TA402.
In current weeks and months, Wirte has leveraged the Gaza conflict to unfold phishing assaults in opposition to authorities entities unfold throughout the area. It has additionally been finishing up wiper assaults in Israel. “It shows that Hamas still has cyber capabilities, even with the ongoing war,” says Sergey Shykevich, menace intelligence group supervisor at Examine Level.
Wirte’s Spying and Wiping Assaults
Wirte assaults should not notably distinctive or subtle. A PDF in an electronic mail would possibly comprise a hyperlink directing targets to a file for obtain, named not directly to lend it legitimacy (e.g., “Beirut — Developments of the War in Lebanon 2”). The file will comprise a lure doc, a number of respectable 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 objective of irritating evaluation. It employs geofencing, and reflective loaders that run code immediately in reminiscence, slightly than on the disk, the place it’d in any other case be noticed by antivirus software program.
In an espionage-focused assault, the tip of this chain would possibly convey 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 tackle of a respectable Israeli reseller of ESET software program. Its lure message — despatched to hospitals, municipal governments, and others — warned recipients that “Government-based attackers may be trying to compromise your device!” and included a obtain hyperlink. The hyperlink first tried to hook up with the web site for Israel’s House 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 instrument 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 main 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 strategy to Israel. And on this means, it has additionally mirrored different Palestinian menace actors.
“Before the war, it was focused mostly 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 become more and more about making [breaches] public, showing the data, the destruction. The focus is more and more on hack-and-leak operations, and how they can use cyber capabilities to try to shape a narrative.”
