Microsoft has revealed that North Korea-linked state-sponsored cyber actors have begun to use artificial intelligence (AI) to make its operations more effective and efficient. "They are learning to use tools powered by AI large language models (LLM) to make their operations more efficient and effective," the tech giant  said  in its latest report on East Asia hacking groups. The company specifically highlighted a group named  Emerald Sleet  (aka Kimusky or TA427), which has been observed using LLMs to bolster spear-phishing efforts aimed at Korean Peninsula experts. The adversary is also said to have relied on the latest advancements in AI to research vulnerabilities and conduct reconnaissance on organizations and experts focused on North Korea, joining  hacking crews from China , who have turned to AI-generated content for influence operations. It further employed LLMs to troubleshoot technical issues, conduct basic scripting tasks, and draft content for spear-phishing

Multiple companies operating in the cryptocurrency sector are the target of an ongoing malware campaign that involves a newly discovered Apple macOS backdoor codenamed RustDoor. RustDoor was  first documented  by Bitdefender last week, describing it as a Rust-based malware capable of harvesting and uploading files, as well as gathering information about the infected machines. It's distributed by masquerading itself as a Visual Studio update. While prior evidence uncovered at least three different variants of the backdoor, the exact initial propagation mechanism remained unknown. That said, the Romanian cybersecurity firm subsequently told The Hacker News that the malware was used as part of a targeted attack rather than a shotgun distribution campaign, noting that it found additional artifacts that are responsible for downloading and executing RustDoor. "Some of these first stage downloaders claim to be PDF files with job offerings, but in reality, are scripts that downl

Imagine a world where the software that powers your favorite apps, secures your online transactions, and keeps your digital life could be outsmarted and taken over by a cleverly disguised piece of code. This isn't a plot from the latest cyber-thriller; it's actually been a reality for years now. How this will change – in a positive or negative direction – as artificial intelligence (AI) takes on a larger role in software development is one of the big uncertainties related to this brave new world. In an era where AI promises to revolutionize how we live and work, the conversation about its security implications cannot be sidelined. As we increasingly rely on AI for tasks ranging from mundane to mission-critical, the question is no longer just, "Can AI  boost cybersecurity ?" (sure!), but also "Can AI  be hacked? " (yes!), "Can one use AI  to hack? " (of course!), and "Will AI  produce secure software ?" (well…). This thought leadership article is about the latter. Cydrill  (a

The Russian threat actor known as  Shuckworm  has continued its cyber assault spree against Ukrainian entities in a bid to steal sensitive information from compromised environments. Targets of the recent intrusions, which began in February/March 2023, include security services, military, and government organizations, Symantec  said  in a new report shared with The Hacker News. "In some cases, the Russian group succeeded in staging long-running intrusions, lasting for as long as three months," the cybersecurity company said. "The attackers repeatedly attempted to access and steal sensitive information such as reports about the deaths of Ukrainian service members, reports from enemy engagements and air strikes, arsenal inventory reports, training reports, and more." Shuckworm, also known by the names Aqua Blizzard (formerly Actinium), Armageddon, Gamaredon, Iron Tilden, Primitive Bear, Trident Ursa, UNC530, and Winterflounder, is attributed to the Russia's Fe

The threat actors behind  RomCom RAT  are leveraging a network of fake websites advertising rogue versions of popular software at least since July 2022 to infiltrate targets. Cybersecurity firm Trend Micro is tracking the activity cluster under the name Void Rabisu, which is also known as Tropical Scorpius (Unit 42) and UNC2596 (Mandiant). "These lure sites are most likely only meant for a small number of targets, thus making discovery and analysis more difficult," security researchers Feike Hacquebord, Stephen Hilt, Fernando Merces, and Lord Alfred Remorin  said . Some of the impersonated apps spotted so far include AstraChat, Devolutions' Remote Desktop Manager, Gimp, GoTo Meeting, KeePass, OpenAI ChatGPT, Signal, Veeam Backup & Replication, and WinDirStat. RomCom RAT was  first chronicled  by Palo Alto Networks Unit 42 in August 2022, linking it to a financially motivated group deploying  Cuba Ransomware  (aka COLDDRAW). It's worth noting that there is no

A notorious advanced persistent threat actor known as  Mustang Panda  has been linked to a spate of spear-phishing attacks targeting government, education, and research sectors across the world. The primary targets of the intrusions from May to October 2022 included counties in the Asia Pacific region such as Myanmar, Australia, the Philippines, Japan, and Taiwan, cybersecurity firm Trend Micro  said  in a Friday report.  Mustang Panda, also called Bronze President, Earth Preta, HoneyMyte, and Red Lich, is a China-based espionage actor believed to be active since at least July 2018. The group is known for its use of malware such as China Chopper and PlugX to collect data from compromised environments. Activities of the group chronicled by  ESET ,  Google, Proofpoint ,  Cisco Talos , and  Secureworks  this year have revealed the threat actor's pattern of using PlugX (and its variant called Hodur) to infect a wide range of entities in Asia, Europe, the Middle East, and the Ameri

Cybersecurity agencies across Asia and Europe have issued multiple security alerts regarding the resurgence of email-based Emotet malware attacks targeting businesses in France, Japan, and New Zealand. "The emails contain malicious attachments or links that the receiver is encouraged to download," New Zealand's Computer Emergency Response Team (CERT) said. "These links and attachments may look like genuine invoices, financial documents, shipping information, resumes, scanned documents, or information on COVID-19, but they are fake." Echoing similar concerns, Japan's CERT (JPCERT/CC) cautioned it found a rapid increase in the number of domestic domain (.jp) email addresses that have been infected with the malware and can be misused to send spam emails in an attempt to spread the infection further. First identified in 2014 and distributed by a threat group tracked as TA542 (or Mummy Spider), Emotet has since evolved from its original roots as a s

An unpatched security weakness in Google Drive could be exploited by malware attackers to distribute malicious files disguised as legitimate documents or images, enabling bad actors to perform spear-phishing attacks comparatively with a high success rate. The latest security issue—of which Google is aware but, unfortunately, left unpatched—resides in the " manage versions " functionality offered by Google Drive that allows users to upload and manage different versions of a file, as well as in the way its interface provides a new version of the files to the users. Logically, the manage versions functionally should allow Google Drive users to update an older version of a file with a new version having the same file extension, but it turns out that it's not the case. According to A. Nikoci, a system administrator by profession who reported the flaw to Google and later disclosed it to The Hacker News, the affected functionally allows users to upload a new version wit

Today, cybersecurity researchers shed light on an Iranian cyber espionage campaign directed against critical infrastructures in Kuwait and Saudi Arabia. Bitdefender said the intelligence-gathering operations were conducted by Chafer APT (also known as APT39 or Remix Kitten), a threat actor known for its attacks on telecommunication and travel industries in the Middle East to collect personal information that serves the country's geopolitical interests. "Victims of the analyzed campaigns fit into the pattern preferred by this actor, such as air transport and government sectors in the Middle East," the researchers said in a report (PDF) shared with The Hacker News, adding at least one of the attacks went undiscovered for more than a year and a half since 2018. "The campaigns were based on several tools, including 'living off the land' tools, which makes attribution difficult, as well as different hacking tools and a custom-built backdoor." Kn

Open source developers who use the popular code-sharing site GitHub were put on alert after the discovery of a phishing email campaign that attempts to infect their computers with an advanced malware trojan. Dubbed Dimnie , the reconnaissance and espionage trojan has the ability to harvest credentials, download sensitive files, take screenshots, log keystrokes on 32-bit and 64-bit architectures, download additional malware on infected systems, and self-destruct when ordered to. The malware has largely flown under the radar for the past three years – Thanks to its stealthy command and control methods. The threat was discovered in the mid of January this year when it was targeting multiple owners of Github repositories via phishing emails, but cyber-security firm Palo Alto, who reported the campaign on Tuesday, says the attacks started a few weeks before. Here's How the Attack Works: The attack starts by spamming the email inboxes of active GitHub users with booby-trap

Just a few hours after Donald Trump won the 2016 US Presidential Election, a hacking group launched a wave of cyber attacks targeting U.S.-based policy think-tanks with a new spear phishing campaign designed to fool victims into installing malware. The group of nation-state hackers, also known as Cozy Bear , APT29 , and CozyDuke , is the one of those involved in the recent data breach of the Democratic National Committee (DNC) and is allegedly tied to the Russian government. On Wednesday, the hackers sent a series of phishing emails to dozens of targets associated with non-governmental organizations (NGOs), policy think tanks in the US and even inside the US government, said security firm Volexity. Phishing Attacks Powered by 'PowerDuke' Malware The phishing emails were sent from purpose-built Gmail accounts and other compromised email accounts at Harvard University's Faculty of Arts and Sciences (FAS), trying to trick victims into opening tainted attachments

In Brief The Microsoft's Windows Defender Advanced Threat Hunting team detected that a cyber espionage group of hackers, known as PLATINUM, has found a way to turn the Windows's Hotpatching technique (a way of updating the operating system without requiring a restart) to hide its malware from Antivirus products. PLATINUM group has been active since 2009 and launching large-scale attacks against governmental organizations, intelligence agencies, defense institutes and telecommunication providers in South and Southeast Asia. Practically speaking, the most important thing for a sophisticated APT hacker and a cyber-espionage group is to remain undetected for the longest possible period. Well, that's exactly what an APT (Advanced Persistent Threat) group has achieved. The Microsoft's Windows Defender Advanced Threat Hunting team has discovered that an APT group, dubbed Platinum, has been spying on high-profile targets by abusing a " novel " technique called

The Internet Corporation for Assigned Names and Numbers (ICANN) has been hacked by unknown attackers that allowed them to gain administrative access to some of the organization's systems, the organization confirmed. The attackers used " spear phishing " campaign to target sensitive systems operated by ICANN and sent spoofed emails disguised as internal ICANN communications to its staff members. The link in the emails took the staff to bogus login page, where they provided their usernames and passwords with the keys to their work email accounts. The data breach began in late November 2014 and was discovered a week later, ICANN, which oversees the Internet's address system, said in a release published Tuesday. ICANN is the organization that manages the global top-level domain system. " We believe a 'spear phishing' attack was initiated in late November 2014 ," Tuesday's press release stated. " It involved email messages that we

You all are quite aware of phishing attacks , and for those who are not, Phishing scams are typically fraudulent email messages, masquerading as a well known and trustworthy entity in an attempt to gather personal and financial information from victims. However, phishing attacks have become more sophisticated recently. The Pro-hacker group, Syrian Electronic Army (SEA) is also popular for its advance phishing attack and had purposely targeted twitter account and websites of various popular brands like Forbes, Microsoft, Obama, Facebook, CNN, eBay and PayPal in the past using phishing techniques. Security researchers have seen an increase in the number of phishing attacks every day, but recently a tricky scam came across by the researchers at the Symantec , which is targeting Google Docs and Google Drive users. Under this phishing scam, an email with a subject of " Documents ", tricks recipient to view an ' important document ' stored on the Google Docs by cli

Hackers broke into an Israeli defense ministry computer via an email attachment tainted with malicious software. Reuters reported Israeli Defense is the latest illustrious victim of the Spear Phishing Attack , and hackers penetrated into an Israeli defense ministry computer using a malicious email as a vector. Aviv Raff , Chief Technology officer at Seculert , confirmed that an Email with a malicious attachment that looked like it had been sent by the country's Shin Bet Secret Security Service. The attackers have penetrated into the network of Israeli Defense accessing to 15 computers, one of them managed by the Israel's Civil Administration that monitors Palestinians in Israeli-occupied territory. The Civil Administration is a unit of Israel's Defense Ministry that control the passage of goods between Israel and the West Bank and Gaza Strip. It is clear that the information contained in the infected system represents a precious target for someone that intend to examin

A Chinese malware campaign called ' Beebus ' specifically targeting the aerospace and defense industries has been uncovered by FireEye security researchers. Beebus is designed to steal information, and begins its infiltration, as so many attacks do, with spear-phishing emails. Operation Beebus very related to Operation Shady RAT and was first detected in April 2011. The attacks carried out by  spear phishing attack and drive-by downloads as a means of infecting end users. malicious Whitepapers or PDFs were mailed to targets and by using known flaws, malware was able install Trojan backdoors on vulnerable systems. The malware communicates with a remote command and control (CnC) server. FireEye discovered the attacks on some of its customers in the aerospace and defence last March and the Vulnerability in the Windows OS known as DLL search order hijacking was used to drops a DLL called ntshrui.DLL in the C:\Windows directory.  It has modules to capture system information l
