New BiBi-Windows Wiper Targets Windows Systems in Pro-Hamas Attacks

Cybersecurity researchers have warned about a Windows version of a wiper malware that was earlier observed concentrating on Linux programs in cyber attacks aimed at Israel.

Dubbed BiBi-Windows Wiper by BlackBerry, the wiper is the Windows counterpart of BiBi-Linux Wiper, which has been place to use by a pro-Hamas hacktivist team in the wake of the Israel-Hamas war previous month.

“The Windows variant […] confirms that the threat actors who produced the wiper are continuing to establish out the malware, and suggests an enlargement of the attack to focus on stop person machines and application servers,” the Canadian organization claimed Friday.

Slovak cybersecurity business is monitoring the actor powering the wiper underneath the name BiBiGun, noting that the Windows variant (bibi.exe) is created to overwrite information in the C:Buyers listing recursively with junk knowledge and appends .BiBi to the filename.

The BiBi-Windows Wiper artifact is claimed to have been compiled on October 21, 2023, two months immediately after the onset of the war. The exact method by which it is dispersed is at this time unfamiliar.

In addition to corrupting all files with the exception of people with .exe, .dll, and .sys extensions, the wiper deletes shadow copies from the process, correctly preventing the victims from recovering their information.

A different noteworthy similarity with its Linux variant is its multithreading functionality.

“For the speediest possible destruction motion, the malware operates 12 threads with eight processor cores,” Dmitry Bestuzhev, senior director of cyber risk intelligence at BlackBerry, explained.

It truly is not immediately apparent if the wiper has been deployed in serious-world attacks, and if so, who the targets are.

The development will come as Security Joes, which 1st documented BiBi-Linux Wiper, said the malware is section of a “much larger campaign focusing on Israeli corporations with the deliberate intent to disrupt their working day-to-working day functions making use of knowledge destruction.”

The cybersecurity firm mentioned it determined tactical overlaps amongst the hacktivist team, who simply call on their own Karma, and one more geopolitically determined actor codenamed Moses Staff (aka Cobalt Sapling), which is suspected to be of Iranian origin.

“Despite the fact that the campaign has generally centered all-around Israeli IT and authorities sectors up to this place, some of the participating teams, such as Moses Staff members, have a background of at the same time concentrating on companies throughout various company sectors and geographical areas,” Security Joes said.
