A longstanding menace actor affiliated with Hamas has been conducting espionage in opposition to governments throughout the Center East and damaging 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 latest 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 continued struggle,” says Sergey Shykevich, menace intelligence group supervisor at Examine Level.
Wirte’s Spying and Wiping Assaults
Wirte assaults are usually not significantly distinctive or subtle. A PDF in an electronic mail would possibly include a hyperlink directing targets to a file for obtain, named in a roundabout way to lend it legitimacy (e.g., “Beirut — Developments of the Struggle in Lebanon 2”). The file will include a lure doc, a number of professional 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 posh, 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, fairly 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 would possibly convey the open supply penetration testing framework “Havoc.” Havoc allows persistent entry to a compromised machine, helpful for establishing distant management, performing lateral motion, stealing knowledge, and extra.
In February and October 2024, against this, Wirte campaigns climaxed with the deployment of a wiper referred to as “SameCoin.”
Final month, Wirte puppetted the e-mail deal with of a professional 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 making an attempt to compromise your machine!” and included a obtain hyperlink. The hyperlink first tried to connect with the web site for Israel’s House Entrance Command, a wing of the Israel Protection Forces (IDF) chargeable for defending civilians. Its website 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 Needs
Wirte spying has crossed into Egypt and Saudi Arabia, however its favored targets seem 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 strategy to Israel. And on this means, 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 phobia assault that killed greater than 1,000 Israelis and led to the seize of almost 250 extra.
“Now, it has turn out to be increasingly more about making [breaches] public, exhibiting the information, the destruction. The main target is increasingly more on hack-and-leak operations, and the way they’ll use cyber capabilities to attempt to form a story.”
