A cloud threat actor group tracked as 8220 has updated its malware toolset to breach Linux servers with the goal of installing crypto miners as part of a long-running campaign. "The updates include the deployment of new versions of a crypto miner and an IRC bot," Microsoft Security Intelligence said in a series of tweets on Thursday. "The group has actively updated its techniques and payloads over the last year." 8220, active since early 2017 , is a Chinese-speaking, Monero-mining threat actor so named for its preference to communicate with command-and-control (C2) servers over port 8220. It's also the developer of a tool called whatMiner, which has been co-opted by the Rocke cybercrime group in their attacks. In July 2019, the Alibaba Cloud Security Team uncovered an extra shift in the adversary's tactics, noting its use of rootkits to hide the mining program. Two years later, the gang resurfaced with Tsunami IRC botnet variants and a custom "

The notorious North Korea-backed hacking collective Lazarus Group is suspected to be behind the recent $100 million altcoin theft from Harmony Horizon Bridge, citing similarities to the  Ronin bridge attack  in March 2022. The finding comes as Harmony  confirmed  that its Horizon Bridge, a  platform  that allows users to move cryptocurrency across different blockchains, had been breached last week. The incident involved the exploiter carrying out multiple transactions on June 23 that extracted tokens stored in the bridge and subsequently making away with about $100 million in cryptocurrency. "The stolen crypto assets included Ether (ETH), Tether (USDT), Wrapped Bitcoin (WBTC) and BNB," blockchain analytics company Elliptic  said  in a new report. "The thief immediately used Uniswap – a decentralized exchange (DEX) – to convert much of these assets into a total of 85,837 ETH." Days later, on June 27, the culprit is said to have begun moving funds amounting to $

The introduction of Open AI's ChatGPT was a defining moment for the software industry, touching off a GenAI race with its November 2022 release. SaaS vendors are now rushing to upgrade tools with enhanced productivity capabilities that are driven by generative AI. Among a wide range of uses, GenAI tools make it easier for developers to build software, assist sales teams in mundane email writing, help marketers produce unique content at low cost, and enable teams and creatives to brainstorm new ideas.  Recent significant GenAI product launches include Microsoft 365 Copilot, GitHub Copilot, and Salesforce Einstein GPT. Notably, these GenAI tools from leading SaaS providers are paid enhancements, a clear sign that no SaaS provider will want to miss out on cashing in on the GenAI transformation. Google will soon launch its SGE "Search Generative Experience" platform for premium AI-generated summaries rather than a list of websites.  At this pace, it's just a matter of a short time befo

A recently patched  critical security flaw  in Atlassian Confluence Server and Data Center products is being actively weaponized in real-world attacks to drop cryptocurrency miners and ransomware payloads. In at least two of the Windows-related incidents observed by cybersecurity vendor Sophos, adversaries exploited the vulnerability to deliver Cerber ransomware and a  crypto miner  called z0miner on victim networks. The bug ( CVE-2022-26134 , CVSS score: 9.8), which was  patched  by Atlassian on June 3, 2022, enables an unauthenticated actor to inject malicious code that paves the way of remote code execution (RCE) on affected installations of the collaboration suite. All supported versions of Confluence Server and Data Center are affected. Other notable malware pushed as part of disparate instances of attack activity include Mirai and Kinsing bot variants, a rogue package called  pwnkit , and Cobalt Strike by way of a web shell deployed after gaining an initial foothold into the

Cybercriminals are impersonating popular crypto platforms such as Binance, Celo, and Trust Wallet with spoofed emails and fake login pages in an attempt to steal login details and deceptively transfer virtual funds. "As cryptocurrency and non-fungible tokens (NFTs) become more mainstream, and capture headlines for their volatility, there is a greater likelihood of more individuals falling victim to fraud attempting to exploit people for digital currencies," Proofpoint  said  in a new report. "The rise and proliferation of cryptocurrency has also provided attackers with a new method of financial extraction." The targeting of sensitive cryptocurrency data by threat actors was recently echoed by the Microsoft 365 Defender Research Team, which warned about the emerging threat of  cryware  wherein private keys, seed phrases, and wallet addresses are plundered with the goal of siphoning virtual currencies by means of fraudulent transfers. The  swift popularity of We

An illicit online marketplace known as SSNDOB was taken down in operation led by U.S. law enforcement agencies, the Department of Justice (DoJ) announced Tuesday. SSNDOB trafficked in personal information such as names, dates of birth, credit card numbers, and Social Security numbers of about 24 million individuals in the U.S., generating its operators $19 million in sales revenue. The action saw the seizure of several domains associated with the marketplace — ssndob.ws, ssndob.vip, ssndob.club, and blackjob.biz — in cooperation with authorities from Cyprus and Latvia. According to blockchain analytics firm  Chainalysis , SSNDOB's Bitcoin payment processing system has received nearly $22 million worth of Bitcoin across over 100,000 transactions since April 2015. Furthermore, bitcoin transfers to the tune of more than $100,000 have been unearthed between SSNDOB and  Joker's Stash , another darknet market that specialized in stolen credit card information and voluntarily c

Microsoft is warning of an emerging threat targeting internet-connected cryptocurrency wallets, signaling a departure in the use of digital coins in cyberattacks. The tech giant dubbed the new threat "cryware," with the attacks resulting in the irreversible theft of virtual currencies by means of fraudulent transfers to an adversary-controlled wallet. "Cryware are information stealers that collect and exfiltrate data directly from non-custodial cryptocurrency wallets, also known as  hot wallets ," Berman Enconado and Laurie Kirk of the Microsoft 365 Defender Research Team  said  in a new report.  "Because hot wallets, unlike custodial wallets, are stored locally on a device and provide easier access to cryptographic keys needed to perform transactions, more and more threats are targeting them." Attacks of this kind are not theoretical. Earlier this year, Kaspersky  disclosed  a financially-motivated campaign staged by the North Korea-based Lazarus Gr

Microsoft is warning of a new variant of the Sysrv botnet that's exploiting multiple security flaws in web applications and databases to install coin miners on both Windows and Linux systems. The tech giant, which has called the new version Sysrv-K , is said to weaponize an  array of exploits  to gain control of web servers. The cryptojacking botnet first emerged in December 2020. "Sysrv-K scans the internet to find web servers with various vulnerabilities to install itself," the company  said  in a series of tweets. "The vulnerabilities range from path traversal and remote file disclosure to arbitrary file download and remote code execution vulnerabilities." This also includes  CVE-2022-22947  (CVSS score: 10.0), a code injection vulnerability in Spring Cloud Gateway that could be exploited to allow arbitrary remote execution on a remote host via a maliciously crafted request. It's worth noting that the abuse of CVE-2022-22947 has prompted the U.S. Cy

The U.S. Treasury Department on Friday moved to sanction virtual currency mixer Blender.io, marking the first time a mixing service has been subjected to economic blockades. The move signals continued efforts on the part of the government to prevent North Korea's Lazarus Group from laundering the funds stolen from the  unprecedented hack of Ronin Bridge  in late March. The newly imposed sanctions, issued by the U.S. Office of Foreign Assets Control (OFAC), target 45 Bitcoin addresses linked to Blender.io and four new wallets linked to Lazarus Group, an advanced persistent with ties to the Democratic People's Republic of Korea (DPRK). "Blender was used in processing over $20.5 million of the illicit proceeds," the Treasury  said , adding it was utilized by DPRK to "support its malicious cyber activities and money-laundering of stolen virtual currency." Cryptocurrency mixers, also called  tumblers , are privacy-focused services that allow users to move cr

The U.S. Securities and Exchange Commission (SEC) on Tuesday announced that it will expand and rebrand its Cyber Unit to fight against cyber-related threats and protect investors in cryptocurrency markets. To that end, the SEC is renaming the Cyber Unit within the  Division of Enforcement  to Crypto Assets and Cyber Unit and plans to infuse 20 additional positions with the goal of investigating wrongdoing in the crypto markets. The goal, per the agency, is to tackle cryptocurrency fraud and crackdown on  malicious actors  attempting to profit from crypto marketplaces. The Cyber Unit was  instituted  in September 2017 with a focus on addressing cyber-based threats and protecting retail investors. But given the dramatic evolution of the digital assets markets in recent years, the new unit is expected to focus on securities law violations pertaining to - Crypto asset offerings Crypto asset exchanges Crypto asset lending and staking products Decentralized finance (DeFi) platforms

A security vulnerability has been disclosed in the web version of the Ever Surf wallet that, if successfully weaponized, could allow an attacker to gain full control over a victim's wallet. "By exploiting the vulnerability, it's possible to decrypt the private keys and seed phrases that are stored in the browser's local storage," Israeli cybersecurity company Check Point said in a report shared with The Hacker News. "In other words, attackers could gain full control over the victim's wallets." Ever Surf  is a cryptocurrency wallet for the Everscale (formerly FreeTON) blockchain that also doubles up as a cross-platform messenger and allows users to access decentralized apps as well as send and receive non-fungible tokens (NFTs). It's said to have an  estimated  669,700 accounts across the world. By means of different attack vectors like malicious browser extensions or phishing links, the flaw makes it possible to obtain a wallet's encr

LemonDuck, a cross-platform cryptocurrency mining botnet, is targeting Docker to mine cryptocurrency on Linux systems as part of an active malware campaign. "It runs an anonymous mining operation by the use of proxy pools, which hide the wallet addresses," CrowdStrike  said  in a new report. "It evades detection by targeting Alibaba Cloud's monitoring service and disabling it." Known to strike both Windows and Linux environments, LemonDuck is primarily engineered for abusing the system resources to mine Monero. But it's also capable of credential theft, lateral movement, and facilitating the deployment of additional payloads for follow-on activities. "It uses a wide range of spreading mechanisms — phishing emails, exploits, USB devices, brute force, among others — and it has shown that it can quickly take advantage of news, events, or the release of new exploits to run effective campaigns," Microsoft  detailed  in a technical write-up of the ma

The U.S. Cybersecurity and Infrastructure Security Agency (CISA), along with the Federal Bureau of Investigation (FBI) and the Treasury Department, warned of a new set of ongoing cyber attacks carried out by the Lazarus Group targeting blockchain companies. Calling the activity cluster  TraderTraitor , the infiltrations involve the North Korean state-sponsored advanced persistent threat (APT) actor striking entities operating in the Web3.0 industry since at least 2020. Targeted organizations include cryptocurrency exchanges, decentralized finance (DeFi) protocols, play-to-earn cryptocurrency video games, cryptocurrency trading companies, venture capital funds investing in cryptocurrency, and individual holders of large amounts of cryptocurrency or valuable non-fungible tokens (NFTs). The attack chains commence with the threat actor reaching out to victims via different communication platforms to lure them into downloading weaponized cryptocurrency apps for Windows and macOS, subse

A U.S. court has sentenced former Ethereum developer Virgil Griffith to five years and three months in prison and pay a $100,000 fine for conspiring with North Korea to help use cryptocurrencies to circumvent sanctions imposed on the country. "There is no question North Korea poses a national security threat to our nation, and the regime has shown time and again it will stop at nothing to ignore our laws for its own benefit," U.S. Attorney Damian Williams  said  in a statement. The sentencing comes more than six months after Griffith  pleaded guilty  to violating the International Emergency Economic Powers Act ( IEEPA ) by offering technical advice to the hermit kingdom with regards to the use of digital currency to bypass economic restrictions. Griffith was arrested in November 2019. North Korea is known to  rely on   cryptocurrency heists  to get around international sanctions and use it to help fund programs to build weapons of mass destruction. Indeed, the nation-st

Cybersecurity researchers have disclosed a now-fixed security flaw in the Rarible non-fungible token (NFT) marketplace that, if successfully exploited, could have led to account takeover and theft of cryptocurrency assets. "By luring victims to click on a malicious NFT, an attacker can take full control of the victim's crypto wallet to steal funds," Check Point researchers Roman Zaikin, Dikla Barda, and Oded Vanunu  said  in a report shared with The Hacker News. Rarible, an NFT marketplace that enables users to create, buy, and sell digital NFT art like photographs, games, and memes, has over 2.1 million active users. "There is still a huge gap between, in terms of security, between Web2 and Web3 infrastructure," Vanunu, head of products vulnerabilities research at Check Point, said in a statement shared with The Hacker News. "Any small vulnerability can possibly allow cyber criminals to hijack crypto wallets behind the scenes. We are still in a state

The North Korean state-backed hacking crew, otherwise known as the  Lazarus Group , has been attributed to yet another financially motivated campaign that leverages a trojanized decentralized finance (DeFi) wallet app to distribute a fully-featured backdoor onto compromised Windows systems. The app, which is equipped with functionalities to save and manage a cryptocurrency wallet, is also designed to trigger the launch of the implant that can take control of the infected host. Russian cybersecurity firm Kaspersky  said  it first encountered the rogue application in mid-December 2021. The infection scheme initiated by the app also results in the deployment of the installer for a legitimate application, which gets overwritten with a trojanized version in an effort to cover its tracks. That said, the initial access avenue is unclear, although it's suspected to be a case of social engineering. The spawned malware, which masquerades as Google's Chrome web browser, subsequently

An unidentified threat actor has been observed employing a "complex and powerful" malware loader with the ultimate objective of deploying cryptocurrency miners on compromised systems and potentially facilitating the theft of Discord tokens. "The evidence found on victim networks appears to indicate that the goal of the attacker was to install cryptocurrency mining software on victim machines," researchers from the Symantec Threat Hunter Team, part of Broadcom Software,  said  in a report shared with The Hacker News. "This would appear to be a relatively low-reward goal for the attacker given the level of effort that would have been required to develop this sophisticated malware." This advanced piece of malware, dubbed Verblecon, is said to have been first spotted two months ago in January 2022, with the payload incorporating  polymorphic qualities  to evade signature-based detections by security software. In addition, the loader carries out further a

Vulnerable routers from MikroTik have been misused to form what cybersecurity researchers have called one of the largest botnet-as-a-service cybercrime operations seen in recent years.  According to a new piece of research published by Avast, a cryptocurrency mining campaign leveraging the new-disrupted  Glupteba botnet  as well as the infamous TrickBot malware were all distributed using the same command-and-control (C2) server. "The C2 server serves as a botnet-as-a-service controlling nearly 230,000 vulnerable MikroTik routers," Avast's senior malware researcher, Martin Hron,  said  in a write-up, potentially linking it to what's now called the Mēris botnet. The botnet is known to exploit a known vulnerability in the Winbox component of MikroTik routers ( CVE-2018-14847 ), enabling the attackers to gain unauthenticated, remote administrative access to any affected device. Parts of the Mēris botnet were  sinkholed  in late  September 2021 . "The  CVE-2018-

Social engineering attacks leveraging a combination of romantic lures and cryptocurrency fraud have been deceiving unsuspecting victims into installing fake apps by taking advantage of legitimate iOS features like TestFlight and Web Clips. Cybersecurity company Sophos, which has named the organized crime campaign " CryptoRom ," characterized it as a wide-ranging global scam. "This style of cyber-fraud, known as sha zhu pan (杀猪盘) — literally 'pig butchering plate' — is a well-organized, syndicated scam operation that uses a combination of often romance-centered social engineering and fraudulent financial applications and websites to ensnare victims and steal their savings after gaining their confidence," Sophos analyst Jagadeesh Chandraiah  said  in a report published last week. The campaign works by approaching potential targets through dating apps like Bumble, Tinder, Facebook Dating, and Grindr, before moving the conversation to messaging apps such as

The malware known as DirtyMoe has gained new worm-like propagation capabilities that allow it to expand its reach without requiring any user interaction, the latest research has found. "The worming module targets older well-known vulnerabilities, e.g.,  EternalBlue  and  Hot Potato  Windows privilege escalation," Avast researcher Martin Chlumecký  said  in a report published Wednesday. "One worm module can generate and attack hundreds of thousands of private and public IP addresses per day; many victims are at risk since many machines still use unpatched systems or weak passwords." Active since 2016, the  DirtyMoe botnet  is used for carrying out cryptojacking and distributed denial-of-service (DDoS) attacks, and is deployed by means of external exploit kits like  Purple Fox  or injected installers of Telegram Messenger. Also employed as part of the attack sequence is a DirtyMoe service that triggers the launch of two additional processes, namely the Core and
