Microsoft is warning of several phishing campaigns that are leveraging tax-related themes to deploy malware and steal credentials. "These campaigns notably use redirection methods such as URL shorteners and QR codes contained in malicious attachments and abuse legitimate services like file-hosting services and business profile pages to avoid detection," Microsoft said in a report shared with The Hacker News. A notable aspect of these campaigns is that they lead to phishing pages that are delivered via a phishing-as-a-service (PhaaS) platform codenamed RaccoonO365 , an e-crime platform that first came to light in early December 2024. Also delivered are remote access trojans (RATs) like Remcos RAT, as well as other malware and post-exploitation frameworks such as Latrodectus , AHKBot, GuLoader , and BruteRatel C4 (BRc4). One such campaign spotted by the tech giant on February 6, 2025, is estimated to have sent hundreds of emails targeting the United States ahead of the t...

The security landscape now moves at a pace no patch cycle can match. Attackers aren't waiting for quarterly updates or monthly fixes—they adapt within hours, blending fresh techniques with old, forgotten flaws to create new openings. A vulnerability closed yesterday can become the blueprint for tomorrow's breach. This week's recap explores the trends driving that constant churn: how threat actors reuse proven tactics in unexpected ways, how emerging technologies widen the attack surface, and what defenders can learn before the next pivot. Read on to see not just what happened, but what it means—so you can stay ahead instead of scrambling to catch up. ⚡ Threat of the Week Google Patches Actively Exploited Chrome 0-Day — Google released security updates for the Chrome web browser to address four vulnerabilities, including one that it said has been exploited in the wild. The zero-day vulnerability, CVE-2025-10585, has been described as a type confusion issue in the V8 JavaScript ...

Cybersecurity researchers have flagged the tactical similarities between the threat actors behind the RomCom RAT and a cluster that has been observed delivering a loader dubbed TransferLoader . Enterprise security firm Proofpoint is tracking the activity associated with TransferLoader to a group dubbed UNK_GreenSec and the RomCom RAT actors under the moniker TA829 . The latter is also known by the names CIGAR, Nebulous Mantis, Storm-0978, Tropical Scorpius, UAC-0180, UAT-5647, UNC2596, and Void Rabisu. The company said it discovered UNK_GreenSec as part of its investigation into TA829, describing it as using an "unusual amount of similar infrastructure, delivery tactics, landing pages, and email lure themes." TA829 is something of an unusual hacking group in the threat landscape given its ability to conduct both espionage as well as financially motivated attacks. The Russia-aligned hybrid group has also been linked to the zero-day exploitation of security flaws in Mozil...

Cryptocurrency users are the target of an ongoing social engineering campaign that employs fake startup companies to trick users into downloading malware that can drain digital assets from both Windows and macOS systems. "These malicious operations impersonate AI, gaming, and Web3 firms using spoofed social media accounts and project documentation hosted on legitimate platforms like Notion and GitHub," Darktrace researcher Tara Gould said in a report shared with The Hacker News. The elaborate social media scam has been for sometime now, with a previous iteration in December 2024 leveraging bogus videoconferencing platforms to dupe victims into joining a meeting under the pretext of discussing an investment opportunity after approaching them on messaging apps like Telegram. Users who ended up downloading the purported meeting software were stealthily infected by stealer malware such as Realst. The campaign was codenamed Meeten by Cado Security (which was acquired by Dark...

The North Korea-linked threat actor known as Konni APT has been attributed to a phishing campaign targeting government entities in Ukraine, indicating the threat actor's targeting beyond Russia . Enterprise security firm Proofpoint said the end goal of the campaign is to collect intelligence on the "trajectory of the Russian invasion." "The group's interest in Ukraine follows historical targeting of government entities in Russia for strategic intelligence gathering purposes," security researchers Greg Lesnewich, Saher Naumaan, and Mark Kelly said in a report shared with The Hacker News. Konni APT , also known as Opal Sleet, Osmium, TA406, and Vedalia , is a cyber espionage group that has a history of targeting entities in South Korea, the United States, and Russia. It's operational since at least 2014. Attack chains mounted by the threat actor often involve the use of phishing emails to distribute malware called Konni RAT (aka UpDog) and redirect r...

A quiet tweak in a popular open-source tool opened the door to a supply chain breach—what started as a targeted attack quickly spiraled, exposing secrets across countless projects. That wasn't the only stealth move. A new all-in-one malware is silently stealing passwords, crypto, and control—while hiding in plain sight. And over 300 Android apps joined the chaos, running ad fraud at scale behind innocent-looking icons. Meanwhile, ransomware gangs are getting smarter—using stolen drivers to shut down defenses—and threat groups are quietly shifting from activism to profit. Even browser extensions are changing hands, turning trusted tools into silent threats. AI is adding fuel to the fire—used by both attackers and defenders—while critical bugs, cloud loopholes, and privacy shakeups are keeping teams on edge. Let's dive into the threats making noise behind the scenes. ⚡ Threat of the Week Coinbase the Initial Target of GitHub Action Supply Chain Breach — The supply chain compromise...

Cybersecurity never slows down. Every week brings new threats, new vulnerabilities, and new lessons for defenders. For security and IT teams, the challenge is not just keeping up with the news—it's knowing which risks matter most right now. That's what this digest is here for: a clear, simple briefing to help you focus where it counts. This week, one story stands out above the rest: the Salesloft–Drift breach, where attackers stole OAuth tokens and accessed Salesforce data from some of the biggest names in tech. It's a sharp reminder of how fragile integrations can become the weak link in enterprise defenses. Alongside this, we'll also walk through several high-risk CVEs under active exploitation, the latest moves by advanced threat actors, and fresh insights on making security workflows smarter, not noisier. Each section is designed to give you the essentials—enough to stay informed and prepared, without getting lost in the noise. ⚡ Threat of the Week Salesloft to Take Drift Of...

Cybersecurity researchers are calling attention to a nefarious campaign targeting WordPress sites to make malicious JavaScript injections that are designed to redirect users to sketchy sites. "Site visitors get injected content that was drive-by malware like fake Cloudflare verification," Sucuri researcher Puja Srivastava said in an analysis published last week. The website security company said it began an investigation after one of its customer's WordPress sites served suspicious third-party JavaScript to site visitors, ultimately finding that the attackers introduced malicious modifications to a theme-related file ("functions.php"). The code inserted into "functions.php" incorporates references to Google Ads, likely in an attempt to evade detection. But, in reality, it functions as a remote loader by sending an HTTP POST request to the domain "brazilc[.]com," which, in turn, responds with a dynamic payload that includes two component...

Cybersecurity researchers have discovered a new, sophisticated remote access trojan called ResolverRAT that has been observed in attacks targeting healthcare and pharmaceutical sectors. "The threat actor leverages fear-based lures delivered via phishing emails, designed to pressure recipients into clicking a malicious link," Morphisec Labs researcher Nadav Lorber said in a report shared with The Hacker News. "Once accessed, the link directs the user to download and open a file that triggers the ResolverRAT execution chain." The activity, observed as recently as March 10, 2025, shares infrastructure and delivery mechanism overlap with phishing campaigns that have distributed information stealer malware such as Lumma and Rhadamanthys, as documented by Cisco Talos and Check Point last year. A notable aspect of the campaign is the use of localized phishing lures, with the emails crafted in the languages predominantly spoken in the targeted countries. This includ...
