The Hacker News - Cybersecurity News and Analysis: ransomware

The US Federal Bureau of Investigation (FBI), Departments of Homeland Security, and Health and Human Services (HHS) issued a joint alert Wednesday warning of an "imminent" increase in ransomware and other cyberattacks against hospitals and healthcare providers. "Malicious cyber actors are targeting the [Healthcare and Public Health] Sector with TrickBot malware, often leading to ransomware attacks, data theft, and the disruption of healthcare services," the Cybersecurity and Infrastructure Security Agency  said  in its advisory. The infamous botnet typically spreads via malicious spam email to unsuspecting recipients and can steal financial and personal data and drop other software, such as ransomware, onto infected systems. It's worth noting that cybercriminals have already used TrickBot against a major healthcare provider,  Universal Health Services , whose systems were crippled by Ryuk ransomware late last month. TrickBot has also seen a severe  disrupt

Microsoft has warned about a new strain of mobile ransomware that takes advantage of incoming call notifications and Android's Home button to lock the device behind a ransom note. The findings concern a variant of a known Android ransomware family dubbed "MalLocker.B" which has now resurfaced with new techniques, including a novel means to deliver the ransom demand on infected devices as well as an obfuscation mechanism to evade security solutions. The development comes amid a huge surge in ransomware attacks against critical infrastructure across sectors, with a 50% increase in the daily average of ransomware attacks in the last three months compared to the first half of the year, and cybercriminals increasingly incorporating double extortion in their playbook. MalLocker has been known for being hosted on malicious websites and circulated on online forums using various social engineering lures by masquerading as popular apps, cracked games, or video players. Pre

As ransomware attacks  against critical infrastructure continue to spike in recent months, cybersecurity researchers have uncovered a new entrant that has been actively trying to conduct multistage attacks on large corporate networks of medical labs, banks, manufacturers, and software developers in Russia. The ransomware gang, codenamed "OldGremlin" and believed to be a Russian-speaking threat actor, has been linked to a series of campaigns at least since March, including a successful attack against a clinical diagnostics laboratory that occurred last month on August 11. "The group has targeted only Russian companies so far, which was typical for many Russian-speaking adversaries, such as  Silence  and  Cobalt , at the beginning of their criminal path," Singaporean cybersecurity firm Group-IB said in a report published today and shared with The Hacker News. "Using Russia as a testing ground, these groups then switched to other geographies to distance thems

A UK man who threatened to publicly release stolen confidential information unless the victims agreed to fulfill his digital extortion demands has finally pleaded guilty on Monday at U.S. federal district court in St. Louis, Missouri. Nathan Francis Wyatt , 39, who is a key member of the infamous international hacking group 'The Dark Overlord,' has been sentenced to five years in prison and ordered to pay $1,467,048 in restitution to his victims. Wyatt, who was extradited to the United States late last year after being held for over two years in the United Kingdom, has pleaded guilty to conspiring to commit aggravated identity theft and computer fraud. U.K. police first arrested Wyatt in September 2016 during an investigation into the hacking of an iCloud account belonging to Pippa Middleton, the younger sister of the British royal family member Duchess of Cambridge, and stealing 3,000 images of her. Though he was released in that case without charge due to lack of

German authorities last week  disclosed  that a ransomware attack on the University Hospital of Düsseldorf (UKD) caused a failure of IT systems, resulting in the death of a woman who had to be sent to another hospital that was 20 miles away. The incident marks the first recorded casualty as a consequence of cyberattacks on critical healthcare facilities, which has ramped up in recent months. The attack, which exploited a Citrix ADC  CVE-2019-19781  vulnerability to cripple the hospital systems on September 10, is said to have been "misdirected" in that it was originally intended for Heinrich Heine University, according to an extortion note left by the perpetrators. After law enforcement contacted the threat actors and informed them that they had encrypted a hospital, the operators behind the attack withdrew the ransom demand and provided the decryption key. The case is currently being treated as a homicide, BBC News  reported  over the weekend. Unpatched Vulnerabilities

Hackers always find a way in, even if there's no software vulnerability to exploit. The FBI has arrested a Russian national who recently traveled to the United States and offered $1 million in bribe to an employee of a targeted company for his help in installing malware into the company's computer network manually. Egor Igorevich Kriuchkov , 27-year-old, entered the United States as a tourist and was arrested in Los Angeles after meeting with the unnamed employee of an undisclosed Nevada-based company numerous times, between August 1 to August 21, to discuss the conspiracy. "On or about July 16, EGOR IGOREVICH KRIUCHKOV used his WhatsApp account to contact the employee of victim company and arranged to visit in person in the District of Nevada," the court documents say. "On or about July 28, EGOR IGOREVICH KRIUCHKOV entered the United States using his Russian Passport and a B1/B2 tourist visa." Kriuchkov also asked the employee to participate in

Garmin, the maker of fitness trackers, smartwatches and GPS-based wearable devices, is currently dealing with a massive worldwide service interruption after getting hit by a targeted ransomware attack, an employee of the company told The Hacker News on condition of anonymity. The company's website and the Twitter account say, "We are currently experiencing an outage that affects Garmin.com and Garmin Connect." "This outage also affects our call centers, and we are currently unable to receive any calls, emails or online chats. We are working to resolve this issue as quickly as possible and apologize for this inconvenience." As a result, the company yesterday was forced to temporarily shut down some of its connected services, including Garmin Express, Garmin Connect mobile, and the website—restricting millions of its users from accessing the cloud services or even syncing their watches locally to the app. Though not much information is available on tech

As hospitals around the world are struggling to respond to the coronavirus crisis, cybercriminals—with no conscience and empathy—are continuously targeting healthcare organizations, research facilities, and other governmental organizations with ransomware and malicious information stealers. The new research, published by Palo Alto Networks and shared with The Hacker News, confirmed that "the threat actors who profit from cybercrime will go to any extent, including targeting organizations that are in the front lines and responding to the pandemic on a daily basis." While the security firm didn't name the latest victims, it said a Canadian government healthcare organization and a Canadian medical research university both suffered ransomware attacks, as criminal groups seek to exploit the crisis for financial gain. The attacks were detected between March 24 and March 26 and were initiated as part of the coronavirus-themed phishing campaigns that have become widespr

In our previous stories, you might have already read about various campaigns warning how threat actors are capitalizing on the ongoing coronavirus pandemic in an attempt to infect your computers and mobile devices with malware or scam you out of your money. Unfortunately, to some extent, it's working, and that's because the attack surface is changing and expanding rapidly as many organizations and business tasks are going digital without much preparation, exposing themselves to more potential threats. Most of the recent cyberattacks are primarily exploiting the fears around the COVID-19 outbreak—fueled by disinformation and fake news—to distribute malware via Google Play apps , malicious links and attachments, and execute ransomware attacks. Here, we took a look at some of the wide range of unseen threats rising in the digital space, powered by coronavirus-themed lures that cybercriminals are using for espionage and commercial gain. The latest development adds to a l

The U.S. Department of Homeland Security's Cybersecurity and Infrastructure Security Agency (CISA) earlier today issued a warning to all industries operating critical infrastructures about a new ransomware threat that if left unaddressed could have severe consequences. The advisory comes in response to a cyberattack targeting an unnamed natural gas compression facility that employed spear-phishing to deliver ransomware to the company's internal network, encrypting critical data and knocking servers out of operation for almost two days. "A cyber threat actor used a spear-phishing link to obtain initial access to the organization's information technology network before pivoting to its operational technology network. The threat actor then deployed commodity ransomware to encrypt data for impact on both networks," CISA noted in its alert. As ransomware attacks continue to escalate in frequency and scale , the new development is yet another indication that p

A new variant of Vega ransomware family, dubbed Zeppelin , has recently been spotted in the wild targeting technology and healthcare companies across Europe, the United States, and Canada. However, if you reside in Russia or some other ex-USSR countries like Ukraine, Belorussia, and Kazakhstan, breathe a sigh of relief, as the ransomware terminates its operations if found itself on machines located in these regions. It's notable and interesting because all previous variants of the Vega family, also known as VegaLocker, were primarily targeting Russian speaking users, which indicates Zeppelin is not the work of the same hacking group behind the previous attacks. Since Vega ransomware and its previous variants were offered as a service on underground forums, researchers at BlackBerry Cylance believes either Zeppelin "ended up in the hands of different threat actors" or "redeveloped from bought/stolen/leaked sources." According to a report BlackBerry Cyl

Targeted ransomware attacks on banking and finance, government , healthcare , and critical infrastructure are on the rise, with the latest victim being the state government of Louisiana. The state government of Louisiana was hit by a large-scale coordinated ransomware attack yesterday, which forced the state to take several state agency servers offline, including government websites, email systems, and other internal applications, to mitigate the risk of the malware's infection from spreading. The Monday's ransomware attack resulted in the subsequent shutdown of a majority of large state agencies, including the Office of the Governor, the Office of Motor Vehicles, the Department of Health, the Department of Children and Family Services, and the Department of Transportation and Development, among others. Louisiana Gov. John Bel Edwards revealed the incident in a series of tweets, saying that he had activated the state's cybersecurity team in response to the cyber

Security researchers have tracked down activities of a new group of financially-motivated hackers that are targeting several businesses and organizations in Germany, Italy, and the United States in an attempt to infect them with backdoor, banking Trojan, or ransomware malware. Though the new malware campaigns are not customized for each organization, the threat actors appear to be more interested in businesses, IT services, manufacturing, and healthcare industries who possess critical data and can likely afford high ransom payouts. According to a report ProofPoint shared with The Hacker News, the newly discovered threat actors are sending out low-volume emails impersonating finance-related government entities with tax assessment and refund lured emails to targeted organizations. "Tax-themed Email Campaigns Target 2019 Filers, finance-related lures have been used seasonally with upticks in tax-related malware and phishing campaigns leading up to the annual tax filing deadlines in

Everis , one of the largest IT consulting companies in Spain, suffered a targeted ransomware attack on Monday, forcing the company to shut down all its computer systems until the issue gets resolved completely. Ransomware is a computer virus that encrypts files on an infected system until a ransom is paid. According to several local media, Everis informed its employees about the devastating widespread ransomware attack, saying: "We are suffering a massive virus attack on the Everis network. Please keep the PCs off. The network has been disconnected with clients and between offices. We will keep you updated." "Please, urgently transfer the message directly to your teams and colleagues due to standard communication problems." According to cybersecurity consultant  Arnau Estebanell Castellví , the malware encrypted files on Everis's computers with an extension name resembling the company's name, i.e., " .3v3r1s ," which suggests the at

THIS WEEK IN THE IRONIC NEWS: DDS Safe, an online cloud-based data backup system that hundreds of dental practice offices across the United States are using to safeguard medical records and other information of their patients from ransomware attacks has been hit with ransomware. Provided by two Wisconsin-based companies, Digital Dental Record and PerCSoft, the backend system of affected medical records retention and backup solutions has probably been hit by Sodinokibi ransomware , also known as Sodin or REvil malware. Though it's not yet clear how attackers managed to compromise the company's infrastructure, the latest ransomware attack is yet another example of successful supply chain attack, crippling computer systems in 400 dental practice offices around the United States this week. According to statements released by both companies, the ransomware virus hit a remote data management software on Monday, August 26, that DDS Safe uses to back up its client data and

The threat of ransomware is becoming more prevalent and severe as attackers' focus has now moved beyond computers to smartphones and other Internet-connected smart devices. In its latest research, security researchers at cybersecurity firm CheckPoint demonstrated how easy it is for hackers to remotely infect a digital DSLR camera with ransomware and hold private photos and videos hostage until victims pay a ransom. Yes, you heard me right. Security researcher Eyal Itkin discovered several security vulnerabilities in the firmware of Canon cameras that can be exploited over both USB and WiFi, allowing attackers to compromise and take over the camera and its features. According to a security advisory  released  by Canon, the reported security flaws affect Canon EOS-series digital SLR and mirrorless cameras, PowerShot SX740 HS, PowerShot SX70 HS, and PowerShot G5X Mark II. "Imagine how would you respond if attackers inject ransomware into both your computer and the c

Yesterday, some residents of Johannesburg, the largest city in South Africa, were left without electricity after the city's power company got attacked by a ransomware virus. City Power, the company responsible for powering South Africa's financial capital Johannesburg, confirmed Thursday on Twitter that it had been hit by a Ransomware virus that had encrypted all of its databases, applications, and network. The attack prevented prepaid customers from buying electricity units, upload invoices when making payments, or access the City Power's official website, eventually leaving them without power. "Please note that the virus hit us early Thursday morning, compromising our database and other software, impacting most of our applications and networks," the city government said in a tweet . However, the company has also ensured its customers that none of their details were compromised in the cyber attack. At the time of writing, the company confirmed they h

A new ransomware family has been found targeting Linux-based Network Attached Storage (NAS) devices made by Taiwan-based QNAP Systems and holding users' important data hostage until a ransom is paid, researchers told The Hacker News. Ideal for home and small business, NAS devices are dedicated file storage units connected to a network or through the Internet, which allow users to store and share their data and backups with multiple computers. Independently discovered by researchers at two separate security firms, Intezer and Anomali, the new ransomware family targets poorly protected or vulnerable QNAP NAS servers either by brute forcing weak SSH credentials or exploiting known vulnerabilities. Dubbed " QNAPCrypt " by Intezer and " eCh0raix " by Anomali, the new ransomware is written in the Go programming language and encrypts files with targeted extensions using AES encryption and appends .encrypt extension to each. However, if a compromised NAS devic
