The Hacker News - Cybersecurity News and Analysis: Cyber Attack

Throughout 2020, businesses, in general, have had their hands full with IT challenges. They had to rush to accommodate a sudden shift to remote work. Then they had to navigate a rapid adoption of automation technologies. And as the year came to a close, more businesses began trying to assemble the safety infrastructure required to return to some semblance of normal in 2021. But at the end of the year,  news of a massive breach  of IT monitoring software vendor SolarWinds introduced a new complication – the possibility of a wave of secondary data breaches and cyber-attacks. And because SolarWinds' products have a presence in so many business networks, the size of the threat is massive. So far, though, most of the attention is getting paid to large enterprises like Microsoft and Cisco (and the US Government), who were the primary target of the SolarWinds breach. What nobody's talking about is the rest of the 18,000 or so SolarWinds clients who may have been affected. For them

An evolving phishing campaign observed at least since May 2020 has been found to target high-ranking company executives across manufacturing, real estate, finance, government, and technological sectors with the goal of obtaining sensitive information. The campaign hinges on a social engineering trick that involves sending emails to potential victims containing fake Office 365 password expiration notifications as lures. The messages also include an embedded link to retain the same password that, when clicked, redirects users to a phishing page for credential harvesting. "The attackers target high profile employees who may not be as technically or cybersecurity savvy, and may be more likely to be deceived into clicking on malicious links," Trend Micro researchers  said  in a Monday analysis. "By selectively targeting C-level employees, the attacker significantly increases the value of obtained credentials as they could lead to further access to sensitive personal and

Cybersecurity researchers on Tuesday disclosed a now-patched security flaw in TikTok that could have potentially enabled an attacker to build a database of the app's users and their associated phone numbers for future malicious activity. Although this flaw only impacts those users who have linked a phone number with their account or logged in with a phone number, a successful exploitation of the vulnerability could have resulted in data leakage and privacy violation, Check Point Research said in an analysis shared with The Hacker News. TikTok has deployed a fix to address the shortcoming following responsible disclosure from Check Point researchers. The newly discovered bug resides in TikTok's " Find friends " feature that allows users to sync their contacts with the service to identify potential people to follow. The contacts are uploaded to TikTok via an HTTP request in the form of a list that consists of hashed contact names and the corresponding phone numbe

Google on Monday disclosed details about an ongoing campaign carried out by a government-backed threat actor from North Korea that has targeted security researchers working on vulnerability research and development. The internet giant's Threat Analysis Group (TAG) said the adversary created a research blog and multiple profiles on various social media platforms such as Twitter, Twitter, LinkedIn, Telegram, Discord, and Keybase in a bid to communicate with the researchers and build trust. The goal, it appears, is to steal exploits developed by the researchers for possibly undisclosed vulnerabilities, thereby allowing them to stage further attacks on vulnerable targets of their choice. "Their blog contains write-ups and analysis of vulnerabilities that have been publicly disclosed, including 'guest' posts from unwitting legitimate security researchers, likely in an attempt to build additional credibility with other security researchers,"  said  TAG researcher A

SonicWall, a popular internet security provider of firewall and VPN products, on late Friday disclosed that it fell victim to a coordinated attack on its internal systems. The San Jose-based company said the attacks leveraged zero-day vulnerabilities in SonicWall secure remote access products such as NetExtender VPN client version 10.x and Secure Mobile Access ( SMA ) that are used to provide users with remote access to internal resources. "Recently, SonicWall identified a coordinated attack on its internal systems by highly sophisticated threat actors exploiting probable zero-day vulnerabilities on certain SonicWall secure remote access products," the company exclusively told The Hacker News. The development comes after The Hacker News received reports that SonicWall's internal systems went down earlier this week on Tuesday and that the source code hosted on the company's GitLab repository was accessed by the attackers. SonicWall wouldn't confirm the re

A relatively new crypto-mining malware that surfaced last year and infected thousands of Microsoft SQL Server (MSSQL) databases has now been linked to a small software development company based in Iran. The attribution was made possible due to an operational security oversight, said researchers from cybersecurity firm Sophos, that led to the company's name inadvertently making its way into the cryptominer code. First documented by Chinese tech giant Tencent last September,  MrbMiner  was found to target internet-facing MSSQL servers with the goal of installing a cryptominer, which hijacks the processing power of the systems to mine Monero and funnel them into accounts controlled by the attackers. The name "MrbMiner" comes after one of the domains used by the group to host their malicious mining software. "In many ways, MrbMiner's operations appear typical of most cryptominer attacks we've seen targeting internet-facing servers,"  said  Gabor Szappa

Microsoft on Wednesday shared more specifics about the tactics, techniques, and procedures (TTPs) adopted by the attackers behind the SolarWinds hack to stay under the radar and avoid detection, as cybersecurity companies work towards getting a "clearer picture" of one of the most sophisticated attacks in recent history. Calling the threat actor "skillful and methodic operators who follow operations security (OpSec) best practices," the company said the attackers went out of their way to ensure that the initial backdoor ( Sunburst  aka Solorigate) and the post-compromise implants ( Teardrop  and  Raindrop ) are separated as much as possible so as to hinder efforts to spot their malicious activity. "The attackers behind Solorigate are skilled campaign operators who carefully planned and executed the attack, remaining elusive while maintaining persistence," researchers from Microsoft 365 Defender Research Team, Microsoft Threat Intelligence Center (MSTIC)

A new large-scale phishing campaign targeting global organizations has been found to bypass Microsoft Office 365 Advanced Threat Protection (ATP) and steal credentials belonging to over a thousand corporate employees. The cyber offensive is said to have originated in August last year, with the attacks aimed specifically at energy and construction companies, said researchers from Check Point Research today in a joint analysis in partnership with industrial cybersecurity firm Otorio. Although phishing campaigns engineered for credential theft are among the most prevalent reasons for data breaches, what makes this operation stand out is an operational security failure that led to the attackers unintentionally exposing the credentials they had stolen to the public Internet. "With a simple Google search, anyone could have found the password to one of the compromised, stolen email addresses: a gift to every opportunistic attacker," the researchers said . The attack chain comm

Cybersecurity researchers have unearthed a fourth new malware strain—designed to spread the malware onto other computers in victims' networks—which was deployed as part of the  SolarWinds supply chain attack  disclosed late last year. Dubbed "Raindrop" by Broadcom-owned Symantec, the malware joins the likes of other malicious implants such as  Sunspot , Sunburst (or Solorigate), and Teardrop that were stealthily delivered to enterprise networks. The latest finding comes amid a continued probe into the breach, suspected to be of  Russian origin , that has claimed a number of U.S. government agencies and private sector companies. "The discovery of Raindrop is a significant step in our investigation of the SolarWinds attacks as it provides further insights into post-compromise activity at organizations of interest to the attackers," Symantec researchers  said . The cybersecurity firm said it discovered only four samples of Raindrop to date that were used to d

An ongoing malware campaign has been found exploiting recently disclosed vulnerabilities in network-attached storage (NAS) devices running on Linux systems to co-opt the machines into an  IRC botnet  for launching distributed denial-of-service (DDoS) attacks and mining Monero cryptocurrency. The attacks deploy a new  malware variant called " FreakOut " by leveraging critical flaws fixed in Laminas Project (formerly Zend Framework) and Liferay Portal as well as an unpatched security weakness in TerraMaster, according to Check Point Research's new analysis published today and shared with The Hacker News. Attributing the malware to be the work of a long-time cybercrime hacker — who goes by the aliases Fl0urite and Freak on HackForums and Pastebin at least since 2015 — the researchers said the flaws —  CVE-2020-28188 ,  CVE-2021-3007 , and  CVE-2020-7961  — were weaponized to inject and execute malicious commands in the server. Regardless of the vulnerabilities exploit

Cybersecurity researchers have  disclosed  a series of attacks by a threat actor of Chinese origin that has targeted organizations in Russia and Hong Kong with malware — including a previously undocumented backdoor. Attributing the campaign to  Winnti  (or APT41), Positive Technologies dated the first attack to May 12, 2020, when the APT used LNK shortcuts to extract and run the malware payload. A second attack detected on May 30 used a malicious RAR archive file consisting of shortcuts to two bait PDF documents that purported to be a curriculum vitae and an IELTS certificate. The shortcuts themselves contain links to pages hosted on Zeplin, a legitimate collaboration tool for designers and developers that are used to fetch the final-stage malware that, in turn, includes a shellcode loader ("svchast.exe") and a backdoor called  Crosswalk  ("3t54dE3r.tmp"). Crosswalk, first documented by FireEye in 2017, is a bare-bones modular backdoor capable of carrying out s

Cybersecurity researchers took the wraps off an ongoing surveillance campaign directed against Colombian government institutions and private companies in the energy and metallurgical industries. In a report published by ESET on Tuesday, the Slovak internet security company said the attacks — dubbed " Operation Spalax " — began in 2020, with the modus operandi sharing some similarities to an APT group targeting the country since at least April 2018, but also different in other ways. The overlaps come in the form of phishing emails, which have similar topics and pretend to come from some of the same entities that were used in a February 2019 operation disclosed by  QiAnXin researchers , and subdomain names used for command-and-control (C2) servers. However, the two campaigns diverge in the attachments used for phishing emails, the remote access trojans (RATs) deployed, and the C2 infrastructure employed to fetch the malware dropped. The attack chain begins with the target

Mimecast said on Tuesday that "a sophisticated threat actor" had compromised a digital certificate it provided to certain customers to securely connect its products to Microsoft 365 (M365) Exchange. The discovery was made after the breach was notified by Microsoft, the London-based company  said in an alert  posted on its website, adding it's reached out to the impacted organizations to remediate the issue. The company didn't elaborate on what type of certificate was compromised, but Mimecast offers  seven different digital certificates  based on the geographical location that must be uploaded to M365 to create a server Connection in Mimecast. "Approximately 10 percent of our customers use this connection," the company said. "Of those that do, there are indications that a low single digit number of our customers' M365 tenants were targeted." Mimecast is a cloud-based email management service for Microsoft Exchange and Microsoft Office 365

Cybersecurity researchers took the wraps off a new spyware operation targeting users in Pakistan that leverages trojanized versions of legitimate Android apps to carry out covert surveillance and espionage. Designed to masquerade apps such as the Pakistan Citizen Porta l, a Muslim prayer-clock app called Pakistan Salat Time , Mobile Packages Pakistan , Registered SIMs Checker , and TPL Insurance , the malicious variants have been found to obfuscate their operations to stealthily download a payload in the form of an Android Dalvik executable (DEX) file. "The DEX payload contains most of the malicious features, which include the ability to covertly exfiltrate sensitive data like the user's contact list and the full contents of SMS messages," Sophos threat researchers Pankaj Kohli and Andrew Brandt said. "The app then sends this information to one of a small number of command-and-control websites hosted on servers located in eastern Europe." Interestingly, t

As the investigation into the SolarWinds supply-chain attack continues, cybersecurity researchers have disclosed a third malware strain that was deployed into the build environment to inject the backdoor into the company's Orion network monitoring platform. Called " Sunspot ," the malignant tool adds to a growing list of previously disclosed malicious software such as Sunburst and Teardrop. "This highly sophisticated and novel code was designed to inject the Sunburst malicious code into the SolarWinds Orion Platform without arousing the suspicion of our software development and build teams," SolarWinds' new CEO Sudhakar Ramakrishna  explained . While  preliminary evidence  found that operators behind the espionage campaign managed to compromise the software build and code signing infrastructure of SolarWinds Orion platform as early as October 2019 to deliver the Sunburst backdoor, the latest findings reveal a new timeline that establishes the first brea

Cybersecurity researchers, for the first time, may have found a potential connection between the backdoor used in  the SolarWinds hack  to a previously known malware strain. In new  research  published by Kaspersky researchers today, the cybersecurity firm said it discovered several features that overlap with another backdoor known as  Kazuar , a .NET-based malware first documented by Palo Alto Networks in 2017. Disclosed early last month, the  espionage campaign  was notable for its scale and stealth, with the attackers leveraging the trust associated with SolarWinds Orion software to infiltrate government agencies and other companies so as to deploy a custom malware codenamed "Sunburst." Shared Features Between Sunburst and Kazuar Attribution for the SolarWinds supply-chain compromise has been difficult in part due to little-to-no clues linking the attack infrastructure to previous campaigns or other well-known threat groups. But Kaspersky's latest analysis of th

A U.S. court on Thursday sentenced a 37-year-old Russian to 12 years in prison for perpetrating an international hacking campaign that resulted in the heist of a trove of personal information from several financial institutions, brokerage firms, financial news publishers, and other American companies. Andrei Tyurin was  charged  with computer intrusion, wire fraud, bank fraud, and illegal online gambling offenses, and for his role in one of the largest thefts of U.S. customer data from a single financial institution in history, which involved the personal information of more than 80 million J.P. Morgan Chase customers. Besides the investment bank, some of the other major targets of the hacks were E*Trade, Scottrade, and the Wall Street Journal. Tyurin, who carried out the extensive hacking from his home in Moscow between 2012 to mid-2015, is believed to have netted over $19 million in criminal proceeds as part of his intrusion schemes. In one such instance of security fraud, Tyu

A North Korean hacking group has been found deploying the RokRat Trojan in a new spear-phishing campaign targeting the South Korean government. Attributing the attack to  APT37  (aka Starcruft, Ricochet Chollima, or Reaper), Malwarebytes said it identified a malicious document last December that, when opened, executes a macro in memory to install the aforementioned remote access tool (RAT). "The file contains an embedded macro that uses a VBA self decoding technique to decode itself within the memory spaces of Microsoft Office without writing to the disk. It then embeds a variant of the RokRat into Notepad," the researchers  noted  in a Wednesday analysis. Believed to be active at least since 2012, the  Reaper APT  is known for its focus on public and private entities primarily in South Korea, such as chemicals, electronics, manufacturing, aerospace, automotive, and healthcare entities. Since then, their victimology has expanded beyond the Korean peninsula to include Ja
