Microsoft has taken apart a destructive Windows backdoor it calls GigaWiper . What stands out is how it is built: not one tool but three older destructive programs bolted into one, offered as commands the operator can choose from. Each is a different way to break a machine: wipe the whole disk, overwrite the Windows drive, or run fake "ransomware" that scrambles files with a key it never saves. Because this is malware and not a single flaw, there is no patch to chase; GigaWiper is what an attacker runs after they are already inside, which makes early detection and clean, offline backups the real defense. The same malicious files show up in a second report under another name: BLUERABBIT , a backdoor Binary Defense flagged last month . Microsoft lists four hashes for the GigaWiper backdoor ; Binary Defense lists the same four for BLUERABBIT , and both command servers match. Binary Defense, citing Google's Threat Intelligence Group, ties the malware to a likely Ir...

Most security mess starts as admin work. A link gets clicked. A tool gets trusted. A bucket name gets reused. A setting stays loose because nobody wants to touch it. This week is full of that kind of damage. Not loud. Not clever. Just small gaps doing big jobs. The worst part is how normal it all looks until the bill arrives. The full ThreatsDay list is below. Global fraud bust Global Operation Leads to ~6K Arrests A global anti-fraud operation involving 97 countries and territories has resulted in the arrest of 5,811 individuals and the interception of $293 million in illicit assets as part of an operation codenamed First Light 2026 that took place between January 15 and April 30, 2026, to tackle social engineering scams and associated money laundering activities. "Over 142,000 victims globally were identified during Operation First Light 2026, highlighting the extent to which social engineering scams and fraud have escalated ...

Cybersecurity researchers have flagged a new ransomware family called GodDamn that employs the PoisonX kernel driver to neutralize security software as part of its defense evasion strategy. According to a new report published by the Threat Hunter Team from Symantec, the ransomware was first publicly spotted in the wild on May 21, 2026. It's assessed to be a rebrand of the Beast ransomware, which, in turn, was an enhanced version of Monster , a Delphi-based ransomware that surfaced in March 2022. Broadcom's cybersecurity arm is tracing the developer behind these ransomware families under the moniker Hyadina. In one attack orchestrated by the ransomware operation in early June 2026, the threat actors are said to have leveraged AnyDesk for remote access and used a NirSoft-based credential harvesting toolkit before deploying the ransomware. The exact initial access vector is unknown. The credential harvester is designed to extract sensitive data from common web browsers, W...

Cybersecurity researchers have disclosed details of a new threat actor dubbed Lurking Lizard that has been operating an end-to-end malicious residential proxy business using an infrastructure comprising more than 230 lookalike domains. The activity dates back to at least August 2022, according to DNS threat intelligence firm Infoblox. Once such campaign, observed earlier this year, involved the actor luring victims with a trojanized 7-Zip installer hosted on a domain named "7zip[.]com," covertly recruiting compromised devices as proxy nodes. Lurking Lizard is also known to impersonate major proxy providers, including IPIDEA , SmartProxy (now Decodo), IP Royal, and 911Proxy, not to mention going to the extent of running fake "independent" review sites to drive traffic to its own scam storefronts. Interestingly, IPIDEA's infrastructure was dismantled by Google in an operation earlier this January.

AI coding assistants have a habit of making things up. Ask one to fetch a popular tool, and it will sometimes hand back a real-sounding name for a project that does not exist. New research, which its authors call  HalluSquatting , turns that habit into an attack: work out the fake names an AI reliably invents, register them first, and wait for the assistant to fetch your trap on a user's behalf. Anyone whose AI assistant can fetch an outside resource and then run commands with little human review is exposed. In tests, that path led the assistant to run attacker-supplied code on the machine. Repeat it with a popular enough resource, and one planted name can reach many machines, which is why the researchers frame it as a way to assemble a botnet. How it works The attack chains two AI quirks. The first is a  hallucination : an AI making something up and presenting it as real. The second is a  prompt injection : a booby-trapped instruction that hijacks the AI, so i...
