Opposition activists in Belarus as well as Ukrainian military and government organizations are the target of a new campaign that employs malware-laced Microsoft Excel documents as lures to deliver a new variant of PicassoLoader .  The threat cluster has been assessed to be an extension of a long-running campaign mounted by a Belarus-aligned threat actor dubbed Ghostwriter (aka Moonscape, TA445, UAC-0057, and UNC1151) since 2016. It's known to align with Russian security interests and promote narratives critical of NATO. "The campaign has been in preparation since July-August 2024 and entered the active phase in November-December 2024," SentinelOne researcher Tom Hegel said in a technical report shared with The Hacker News. "Recent malware samples and command-and-control (C2) infrastructure activity indicate that the operation remains active in recent days." The starting point of the attack chain analyzed by the cybersecurity company is a Google Drive shar...

A threat actor affiliated with Hamas has expanded its malicious cyber operations beyond espionage to carry out disruptive attacks that exclusively target Israeli entities. The activity, linked to a group called WIRTE , has also targeted the Palestinian Authority, Jordan, Iraq, Saudi Arabia, and Egypt, Check Point said in an analysis. "The [Israel-Hamas] conflict has not disrupted the WIRTE's activity, and they continue to leverage recent events in the region in their espionage operations," the company said . "In addition to espionage, the threat actor recently engaged in at least two waves of disruptive attacks against Israel." WIRTE is the moniker assigned to a Middle Eastern advanced persistent threat (APT) that has been active since at least August 2018, targeting a broad spectrum of entities across the region. It was first documented by Spanish cybersecurity company S2 Grupo. The hacking crew is assessed to be part of a politically motivated group ca...

U.S. and Israeli cybersecurity agencies have published a new advisory attributing an Iranian cyber group to targeting the 2024 Summer Olympics and compromising a French commercial dynamic display provider to show messages denouncing Israel's participation in the sporting event. The activity has been pinned on an entity that's known as Emennet Pasargad , which the agencies said has been operating under the cover name Aria Sepehr Ayandehsazan (ASA) since mid-2024. It's tracked by the broader cybersecurity community as Cotton Sandstorm, Haywire Kitten, and Marnanbridge. "The group exhibited new tradecraft in its efforts to conduct cyber-enabled information operations into mid-2024 using a myriad of cover personas, including multiple cyber operations that occurred during and targeting the 2024 Summer Olympics – including the compromise of a French commercial dynamic display provider," according to the advisory . ASA, the U.S. Federal Bureau of Investigation (FBI),...

Ukraine has claimed responsibility for a cyber attack that targeted Russia state media company VGTRK and disrupted its operations, according to reports from Bloomberg and Reuters . The incident took place on the night of October 7, VGTRK confirmed , describing it as an "unprecedented hacker attack." However, it said "no significant damage" was caused and that everything was working normally despite attempts to interrupt radio and TV broadcasts. That said, Russian media outlet Gazeta.ru reported that the hackers wiped "everything" from the company's servers, including backups, citing an anonymous source. A source told Reuters that "Ukrainian hackers 'congratulated' Putin on his birthday by carrying out a large-scale attack on the all-Russian state television and radio broadcasting company." The attack is believed to be the work of a pro-Ukrainian hacker group called Sudo rm-RF . The Russian government has since said an investi...

A hacktivist group known as Twelve has been observed using an arsenal of publicly available tools to conduct destructive cyber attacks against Russian targets. "Rather than demand a ransom for decrypting data, Twelve prefers to encrypt victims' data and then destroy their infrastructure with a wiper to prevent recovery," Kaspersky said in a Friday analysis. "The approach is indicative of a desire to cause maximum damage to target organizations without deriving direct financial benefit." The hacking group, believed to have been formed in April 2023 following the onset of the Russo-Ukrainian war, has a track record of mounting cyber attacks that aim to cripple victim networks and disrupt business operations. It has also been observed conducting hack-and-leak operations that exfiltrate sensitive information, which is then shared on its Telegram channel. Kaspersky said Twelve shares infrastructural and tactical overlaps with a ransomware group called DARKSTA...
