A cyberespionage threat actor known for targeting a variety of critical infrastructure sectors in Africa, the Middle East, and the U.S. has been observed using an upgraded version of a remote access trojan with information stealing capabilities. Calling  TA410  an umbrella group comprised of three teams dubbed FlowingFrog, LookingFrog, and JollyFrog, Slovak cybersecurity firm ESET  assessed  that "these subgroups operate somewhat independently, but that they may share intelligence requirements, an access team that runs their spear-phishing campaigns, and also the team that deploys network infrastructure." TA410 — said to share behavioral and tooling overlaps with  APT10  (aka Stone Panda or TA429) — has a history of targeting U.S.-based organizations in the utilities sector as well as diplomatic entities in the Middle East and Africa. Other identified victims of the hacker collective include a manufacturing company in Japan, a mining business in India, and a charity in Is

Cloudflare on Wednesday disclosed that it acted to mitigate a 15.3 million request-per-second (RPS) distributed denial-of-service (DDoS) attack. The web infrastructure and website security company called it one of the "largest HTTPS DDoS attacks on record."  "HTTPS DDoS attacks are more expensive in terms of required computational resources because of the higher cost of establishing a secure TLS encrypted connection," Cloudflare's Omer Yoachimik and Julien Desgats  said . "Therefore it costs the attacker more to launch the attack, and for the victim to mitigate it." The volumetric DDoS attack is said to have lasted less than 15 seconds and targeted an unnamed Cloudflare customer operating a crypto launchpad.  Volumetric DDoS attacks are designed to overwhelm a target network/service with significantly high volumes of malicious traffic, which typically originate from a botnet under a threat actor's control. Cloudflare said the latest attack w

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

The infamous ransomware group known as Conti has  continued  its onslaught against entities despite suffering a massive data leak of its own earlier this year, according to new research. Conti, attributed to a Russia-based threat actor known as Gold Ulrick , is the second most prevalent malware strain in the ransomware landscape, accounting for  19% of all attacks  during the three-month-period between October and December 2021. One of the most prolific ransomware groups of the last year along the likes of LockBit 2.0, PYSA, and Hive, Conti has locked the networks of hospitals, businesses, and government agencies, while receiving a ransom payment in exchange for sharing the decryption key as part of its name-and-shame scheme. But after the cybercriminal cartel came out in support of Russia over its invasion of Ukraine in February, an anonymous Ukrainian security researcher under the Twitter handle  ContiLeaks  began leaking the source code as well as private conversations between i

The U.S. Federal Bureau of Investigation (FBI) is sounding the alarm on the BlackCat ransomware-as-a-service (RaaS), which it said victimized at least 60 entities worldwide between as of March 2022 since its emergence last November. Also called ALPHV and  Noberus , the malware is notable for being the first-ever ransomware written in the Rust programming language, which is known to be memory safe and offer improved performance. "Many of the developers and money launderers for BlackCat/ALPHV are linked to  DarkSide / BlackMatter , indicating they have extensive networks and experience with ransomware operations," the FBI said in an  advisory  published last week. The disclosure comes weeks after twin reports from  Cisco Talos  and  Kasperksy  uncovered links between BlackCat and BlackMatter ransomware families, including the use of a modified version of a data exfiltration tool dubbed Fendr that's been previously only observed in BlackMatter-related activity. "A

A recent Hive ransomware attack carried out by an affiliate involved the exploitation of "ProxyShell" vulnerabilities in the Microsoft Exchange Server that were disclosed last year to encrypt an unnamed customer's network. "The actor managed to achieve its malicious goals and encrypt the environment in less than 72 hours from the initial compromise," Varonis security researcher, Nadav Ovadia,  said  in a post-mortem analysis of the incident.  Hive, which was  first observed  in June 2021, follows the lucrative ransomware-as-a-service (RaaS) scheme adopted by other cybercriminal groups in recent years, enabling affiliates to deploy the file-encrypting malware after gaining a foothold into their victims' networks. ProxyShell  — tracked as CVE-2021-31207, CVE-2021-34523, and CVE-2021-34473 — involves a combination of security feature bypass, privilege escalation, and remote code execution in the Microsoft Exchange Server, effectively granting the attacker

The Five Eyes nations have released a  joint cybersecurity advisory  warning of increased  malicious attacks  from Russian state-sponsored actors and criminal groups targeting critical infrastructure organizations amidst the ongoing military siege on Ukraine. "Evolving intelligence indicates that the Russian government is exploring options for potential cyberattacks," authorities from Australia, Canada, New Zealand, the U.K., and the U.S.  said . "Russia's invasion of Ukraine could expose organizations both within and beyond the region to increased malicious cyber activity. This activity may occur as a response to the unprecedented economic costs imposed on Russia as well as material support provided by the United States and U.S. allies and partners." The  advisory  follows  another alert  from the U.S. government cautioning of nation-state actors deploying specialized malware to maintain access to industrial control systems (ICS) and supervisory control an

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

The Computer Emergency Response Team of Ukraine (CERT-UA) has warned of a new wave of social engineering campaigns delivering IcedID malware and leveraging Zimbra exploits with the goal of stealing sensitive information. Attributing the IcedID phishing attacks to a threat cluster named UAC-0041, the agency  said  the infection sequence begins with an email containing a Microsoft Excel document (Мобілізаційний реєстр.xls or Mobilization Register.xls) that, when opened, prompts the users to enable macros, leading to the deployment of IcedID. The  information-stealing malware , also known as BokBot, has followed a similar trajectory to that of TrickBot, Emotet, and ZLoader, evolving from its earlier roots as a banking trojan to a full-fledged crimeware service that facilities the retrieval of next-stage implants such as ransomware. The  second set of targeted intrusions  relate to a new threat group dubbed UAC-0097, with the email including a number of image attachments with a  Cont

The U.S. Treasury Department has implicated the North Korea-backed Lazarus Group (aka Hidden Cobra) in the theft of $540 million from video game Axie Infinity's Ronin Network last month. On Thursday, the Treasury  tied  the Ethereum  wallet address  that received the stolen digital currency to the threat actor and sanctioned the funds by adding the address to the Office of Foreign Assets Control's (OFAC) Specially Designated Nationals ( SDN ) List. "The FBI, in coordination with Treasury and other U.S. government partners, will continue to expose and combat the DPRK's use of illicit activities – including cybercrime and cryptocurrency theft – to generate revenue for the regime," the intelligence and law enforcement agency  said  in a statement. The cryptocurrency heist, the second-largest cyber-enabled theft to date, involved the siphoning of 173,600 Ether (ETH) and 25.5 million USD Coins from the Ronin cross-chain bridge, which allows users to transfer their

The U.S. government on Wednesday warned of nation-state actors deploying specialized malware to maintain access to industrial control systems (ICS) and supervisory control and data acquisition (SCADA) devices. "The APT actors have developed custom-made tools for targeting ICS/SCADA devices," multiple U.S. agencies  said  in an alert. "The tools enable them to scan for, compromise, and control affected devices once they have established initial access to the operational technology (OT) network." The joint federal advisory comes courtesy of the U.S. Department of Energy (DoE), the Cybersecurity and Infrastructure Security Agency (CISA), the National Security Agency (NSA), and the Federal Bureau of Investigation (FBI). The custom-made tools are specifically designed to single out Schneider Electric programmable logic controllers (PLCs), OMRON Sysmac NEX PLCs, and Open Platform Communications Unified Architecture (OPC UA) servers. On top of that, the unnamed actors

A threat actor with affiliations to the cyber warfare division of Hamas has been linked to an "elaborate campaign" targeting high-profile Israeli individuals employed in sensitive defense, law enforcement, and emergency services organizations. "The campaign operators use sophisticated social engineering techniques, ultimately aimed to deliver previously undocumented backdoors for Windows and Android devices," cybersecurity company Cybereason  said  in a Wednesday report. "The goal behind the attack was to extract sensitive information from the victims' devices for espionage purposes." The monthslong intrusions, codenamed " Operation Bearded Barbie ," have been attributed to an Arabic-speaking and politically-motivated group called Arid Viper, which operates out of the Middle East and is also known by the monikers APT-C-23 and Desert Falcon. Most recently, the threat actor was  held responsible  for attacks aimed at Palestinian activists

At least three different advanced persistent threat (APT) groups from across the world have launched spear-phishing campaigns in mid-March 2022 using the ongoing Russo-Ukrainian war as a lure to distribute malware and steal sensitive information. The campaigns, undertaken by El Machete, Lyceum, and SideWinder, have targeted a variety of sectors, including energy, financial, and governmental sectors in Nicaragua, Venezuela, Israel, Saudi Arabia, and Pakistan. "The attackers use decoys ranging from official-looking documents to news articles or even job postings, depending on the targets and region," Check Point Research  said  in a report. "Many of these lure documents utilize malicious macros or template injection to gain an initial foothold into the targeted organizations, and then launch malware attacks." The infection chains of  El Machete , a Spanish-speaking threat actor first documented in August 2014 by Kaspersky, involve the use of macro-laced decoy doc

The cyberattack aimed at Viasat that temporarily knocked KA-SAT modems offline on February 24, 2022, the same day Russian military forces invaded Ukraine, is believed to have been the consequence of wiper malware, according to the  latest research  from SentinelOne. The findings come a day after the U.S. telecom company  disclosed  that it was the target of a multifaceted and deliberate" cyberattack against its KA-SAT network, linking it to a "ground-based network intrusion by an attacker exploiting a misconfiguration in a VPN appliance to gain remote access to the trusted management segment of the KA-SAT network." Upon gaining access, the adversary issued "destructive commands" on tens of thousands of modems belonging to the satellite broadband service that "overwrote key data in flash memory on the modems, rendering the modems unable to access the network, but not permanently unusable." But SentinelOne said it uncovered a new piece of malware (

A Belarusian threat actor known as Ghostwriter (aka UNC1151) has been spotted leveraging the recently disclosed browser-in-the-browser (BitB) technique as part of their credential phishing campaigns exploiting the ongoing Russo-Ukrainian conflict. The method, which  masquerades  as a legitimate domain by simulating a browser window within the browser, makes it possible to mount convincing social engineering campaigns. "Ghostwriter actors have quickly adopted this new technique, combining it with a previously observed technique, hosting credential phishing landing pages on compromised sites," Google's Threat Analysis Group (TAG)  said  in a new report, using it to siphon credentials entered by unsuspected victims to a remote server. Among other groups  using the war as a lure  in phishing and malware campaigns to deceive targets into opening fraudulent emails or links include  Mustang Panda  and  Scarab  as well as nation-state actors from Iran, North Korea, and Russia

An independent security researcher has shared what's a detailed timeline of events that transpired as the notorious LAPSUS$ extortion gang broke into a third-party provider linked to the cyber incident at Okta in late January 2022. In a set of screenshots posted on Twitter, Bill Demirkapi  published  a two-page "intrusion timeline" allegedly prepared by Mandiant, the cybersecurity firm hired by Sitel to investigate the security breach. Sitel, through its acquisition of Sykes Enterprises in September 2021, is the third-party service provider that provides customer support on behalf of Okta. The authentication services provider revealed last week that on January 20, it was alerted to a new factor that was added to a Sitel customer support engineer's Okta account, an attempt that it said was successful and blocked. The incident only came to light two months later after LAPSUS$  posted screenshots  on their Telegram channel as evidence of the breach on March 22. The

The U.S. government on Thursday released a cybersecurity advisory outlining multiple intrusion campaigns conducted by state-sponsored Russian cyber actors from 2011 to 2018 that targeted the energy sector in the U.S. and beyond. "The [Federal Security Service] conducted a multi-stage campaign in which they gained remote access to U.S. and international Energy Sector networks, deployed ICS-focused malware, and collected and exfiltrated enterprise and ICS-related data," the U.S. government  said , attributing the attacks to an APT actor known as  Energetic Bear . In addition, the Justice Department  charged  four Russian government employees, including three officers of the Russian Federal Security Service and a computer programmer at the Central Scientific Research Institute of Chemistry and Mechanics (TsNIIKhM), for their roles in carrying out the attacks on oil refineries, nuclear facilities, and energy companies. The four Russian nationals are Pavel Aleksandrovich Akul
