McAfee Lab researchers issued a report on the large scale cyber attacks against South Korea that appear to be linked to hackers also specialized in cyber espionage . The attackers behind these recent attacks against South Korean infrastructure are skilled professionals and they designed a specialized malware to steal military secrets from the South Korea and US military networks. The cyber espionage campaign dubbed as " Operation Troy ", due the numerous references into the source code analyzed to the city. McAfee said that in 2009, malware was implanted into a social media website used by military personnel in South Korea Ryan Sherstobitoff, a senior threat researcher at McAfee, started the investigation after the malware came into action in an attacks occurred on March 20th, known as the Dark Seoul Incident , in which tens of thousands of hard drives belongs to television networks and banks in South Korea were wiped completely. Versions of the code...

Hackers aligned with North Korea have always been accused of attacking and targeting South Korean organizations, financial institutions, banks and media outlets. Recent reports indicate that North Korean hackers have hacked into more than 140,000 computers of at least 160 South Korean government agencies and companies, and allegedly injected malware in the systems. The cyber attack was designed to lay for a long term period against its rival, authorities in Seoul said. The South Korean police were on high alert against cyberattacks by the North Korean hackers, especially after North Korea successfully tested a miniaturized hydrogen bomb in January and a long-range rocket launch in February, Reuters reports . According to the police, the hacking attack began in 2014 but was detected only in February this year, after North Korea managed to steal information from two companies: the SK and Hanjin Group. The documents stolen from the two companies included blueprints for the wi...

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 malware campaign targeting South Korean entities that came to light earlier this year has been attributed to a North Korean nation-state hacking group called Andariel, once again indicating that  Lazarus  attackers are following the trends and their  arsenal  is in  constant development . "The way Windows commands and their options were used in this campaign is almost identical to previous Andariel activity," Russian cybersecurity firm Kaspersky  said  in a deep-dive published Tuesday. Victims of the attack are in the manufacturing, home network service, media, and construction sectors. Designated as part of the Lazarus constellation, Andariel is known for unleashing attacks on South Korean organizations and businesses using specifically tailored methods created for maximum effectivity. In September 2019, the sub-group, along with Lazarus and Bluenoroff, was  sanctioned by the U.S. Treasury Department  for their malicious cyber activity...

The United States Treasury Department on Friday announced sanctions against three state-sponsored North Korean hacking groups for conducting several destructive cyberattacks on US critical infrastructure. Besides this, the hacking groups have also been accused of stealing possibly hundreds of millions of dollars from financial institutions around the world to ultimately fund the North Korean government's illicit weapons and missile programs. The three North Korean hacking groups in question are the well-known Lazarus Group , and its two sub-groups, Bluenoroff and Andariel . The sanctions announced by the Treasury Department's Office of Foreign Assets Control (OFAC) claim that all the three groups are "agencies, instrumentalities, or controlled entities of the Government of North Korea" based on their relationship with Pyongyang's central intelligence bureau called the Reconnaissance General Bureau (RGB). Specifically, the sanctions aim to lock any fore...

There is a new battlefield. It is global and challenging to defend. What began with a high-profile incident back in 2007, when Estonia was hit by hackers targeting its government and commercial sector, has evolved into cyber warfare that is being waged constantly worldwide. Today, cyberattacks have become the norm, transforming how we think about war and international conflict as a whole.  From the 2009 South Korea DDoS attacks to the 2010 attacks on Burma and the 2016 US election interference attacks on the Democratic National Committee, the list of historical cyberwarfare incidents continues to expand. The main players? Nation-state-supported cybercriminal groups and organizations linked to Russia, North Korea, China, and several countries in the Middle East. This report dives into three top cyberwarfare trends in an effort to understand their impact. Russia: The Cyber Invasion of Ukraine  On August 31, 2023, Five Eyes Agency — an intelligence alliance network composed o...

An analysis of the indicators of compromise ( IoCs ) associated with the JumpCloud hack has uncovered evidence pointing to the involvement of North Korean state-sponsored groups, in a style that's reminiscent of the  supply chain attack targeting 3CX . The findings come from SentinelOne, which  mapped out  the infrastructure pertaining to the intrusion to uncover underlying patterns. It's worth noting that JumpCloud, last week,  attributed  the attack to an unnamed "sophisticated nation-state sponsored threat actor." "The North Korean threat actors demonstrate a high level of creativity and strategic awareness in their targeting strategies," SentinelOne security researcher Tom Hegel told The Hacker News. "The research findings reveal a successful and multifaceted approach employed by these actors to infiltrate developer environments." "They actively seek access to tools and networks that can serve as gateways to more extensive opportunitie...

As we are nearing the end of 2022, looking at the most concerning threats of this turbulent year in terms of testing numbers offers a threat-based perspective on what triggers cybersecurity teams to check how vulnerable they are to specific threats. These are the threats that were most tested to validate resilience with the  Cymulate security posture management platform  between January 1st and December 1st, 2022. Manjusaka Date published: August 2022 Reminiscent of Cobalt Strike and Sliver framework (both commercially produced and designed for red teams but misappropriated and misused by threat actors), this emerging attack framework holds the potential to be widely used by malicious actors. Written in Rust and Golang with a User Interface in Simple Chinese (see the workflow diagram below), this software is of Chinese origin. Manjusaka carries Windows and Linux implants in Rust and makes a ready-made C2 server freely available, with the possibility of creating custom im...

Not every risk looks like an attack. Some problems start as small glitches, strange logs, or quiet delays that don't seem urgent—until they are. What if your environment is already being tested, just not in ways you expected? Some of the most dangerous moves are hidden in plain sight. It's worth asking: what patterns are we missing, and what signals are we ignoring because they don't match old playbooks? This week's reports bring those quiet signals into focus—from attacks that bypassed MFA using trusted tools, to supply chain compromises hiding behind everyday interfaces. Here's what stood out across the cybersecurity landscape: ⚡ Threat of the Week Cloudflare Blocks Massive 7.3 Tbps DDoS Attack — Cloudflare said it autonomously blocked the largest distributed denial-of-service (DDoS) attack ever recorded, which hit a peak of 7.3 terabits per second (Tbps). The attack, the company said, targeted an unnamed hosting provider and delivered 37.4 terabytes in 45 seconds. It origi...

The U.S. Department of Justice announces criminal charges against a North Korean government spy in connection with the 2017 global WannaCry ransomware attack and the 2014 Sony Pictures Entertainment hack . According to multiple government officials cited by the NY Times who are familiar with the indictment, the charges would be brought against Park Jin Hyok , who works for North Korean military intelligence agency Reconnaissance General Bureau (RGB). The November 2014 Sony Pictures Entertainment hack was done in retaliation for the studio's production of a comedic film, " The Interview ," a comedy about two journalists who are recruited by the CIA to assassinate North Korean leader Kim Jong Un. In June 2014, the Pyongyang government also denounced the film as "undisguised sponsoring of terrorism, as well as an Act of War" in a letter to U.N. Secretary-General Ban Ki-moon. The Sony Pictures hack was devastating to the company and exposed over 200...

Japanese and U.S. authorities have formerly attributed the theft of cryptocurrency worth $308 million from cryptocurrency company DMM Bitcoin in May 2024 to North Korean cyber actors. "The theft is affiliated with TraderTraitor threat activity, which is also tracked as Jade Sleet, UNC4899, and Slow Pisces," the agencies said . "TraderTraitor activity is often characterized by targeted social engineering directed at multiple employees of the same company simultaneously." The alert comes courtesy of the U.S. Federal Bureau of Investigation (FBI), the Department of Defense Cyber Crime Center, and the National Police Agency of Japan. It's worth noting that DMM Bitcoin shut down its operations earlier this month in the aftermath of the hack. TraderTraitor refers to a North Korea-linked persistent threat activity cluster that has a history of targeting companies in the Web3 sector, luring victims into downloading malware-laced cryptocurrency apps and ultimately ...

The supply chain attack targeting 3CX was the result of a prior supply chain compromise associated with a different company, demonstrating a new level of sophistication with North Korean threat actors. Google-owned Mandiant, which is  tracking  the attack event under the moniker  UNC4736 ,  said  the incident marks the first time it has seen a "software supply chain attack lead to another software supply chain attack." The Matryoshka doll-style cascading attack against 3CX first came to light on March 29, 2023, when it  emerged  that Windows and macOS versions of its communication software were trojanized to deliver a C/C++-based data miner named ICONIC Stealer by means of a downloader, SUDDENICON, that used icon files hosted on GitHub to extract the server containing the stealer. "The malicious application next attempts to steal sensitive information from the victim user's web browser," the U.S. Cybersecurity and Infrastructure Security Agency (CI...

Threat actors such as the notorious Lazarus group are continuing to tap into the ongoing COVID-19 vaccine research to steal sensitive information to speed up their countries' vaccine-development efforts. Cybersecurity firm Kaspersky  detailed  two incidents at a pharmaceutical company and a government ministry in September and October leveraging different tools and techniques but exhibiting similarities in the post-exploitation process, leading the researchers to connect the two attacks to the North Korean government-linked hackers. "These two incidents reveal the Lazarus group's interest in intelligence related to COVID-19," Seongsu Park, a senior security researcher at Kaspersky, said. "While the group is mostly known for its financial activities, it is a good reminder that it can go after strategic research as well." Kaspersky did not name the targeted entities but said the pharmaceutical firm was breached on September 25, 2020, with the attack again...

Koreans have once again gain media attention but this time not as an accused of any kind of hack attack, but as a victim of a severe attack on computers systems at a nuclear power plant in South Korea by an unknown hacker or a group. South Korea was hit by a cyber attack on its nuclear power plant, causing the operator to conduct drills in order to test the ability of the nuclear plant to cope with a full-scale cyber-attack. Although the plant's operator says no critical data has been leaked. The cyber attack came into light after a hacker posted blueprints of nuclear reactors online and threatened further "leaks" unless authorities close down the reactors. According to the South Korean Yonhap News Agency, the hacker was able to access blueprints of reactors, floor maps and other internal information on the plant. Last week with the help of a Twitter account named " president of anti-nuclear reactor group ," the hacker posted leaked data revea...
