Hackers Targeting Critical Healthcare Facilities With Ransomware During Coronavirus Pandemic
April 14, 2020Ravie Lakshmanan
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

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

Ransomware Hits Dental Data Backup Service Offering Ransomware Protection
August 30, 2019Wang Wei
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

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 Is Targeting Network Attached Storage (NAS) Devices

A New Ransomware Is Targeting Network Attached Storage (NAS) Devices
July 10, 2019Mohit Kumar
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

Photo by Terje Pedersen / NTB scanpix One of the world's largest producers of aluminum has been forced to shut down several of its plants across Europe and the U.S. after an "extensive cyber attack" hit its operations, leaving companies' IT systems unusable. According to a press release shared by Aluminum giant Norsk Hydro today, the company has temporarily shut down several plants and switched to manual operations, "where possible," in countries including Norway, Qatar, and Brazil in an attempt to continue some of its operations. The cyber attack, that began in the U.S.,was first detected by the company's IT experts around late Monday evening CET and the company is working to neutralize the attack, as well as investigating to know the full extent of the incident. "Hydro's main priority is to continue to ensure safe operations and limit operational and financial impact. The problem has not led to any safety-related incidents," t

GandCrab ransomware and Ursnif virus spreading via MS Word macros

GandCrab ransomware and Ursnif virus spreading via MS Word macros
January 25, 2019Swati Khandelwal
Security researchers have discovered two separate malware campaigns, one of which is distributing the Ursnif data-stealing trojan and the GandCrab ransomware in the wild, whereas the second one is only infecting victims with Ursnif malware. Though both malware campaigns appear to be a work of two separate cybercriminal groups, we find many similarities in them. Both attacks start from phishing emails containing an attached Microsoft Word document embedded with malicious macros and then uses Powershell to deliver fileless malware. Ursnif is a data-stealing malware that typically steals sensitive information from compromised computers with an ability to harvest banking credentials, browsing activities, collect keystrokes, system and process information, and deploy additional backdoors. Discovered earlier last year, GandCrab is a widespread ransomware threat that, like every other ransomware in the market, encrypts files on an infected system and insists victims to pay a ransom

PyLocky Ransomware Decryption Tool Released — Unlock Files For Free

PyLocky Ransomware Decryption Tool Released — Unlock Files For Free
January 10, 2019Mohit Kumar
If your computer has been infected with PyLocky Ransomware and you are searching for a free ransomware decryption tool to unlock or decrypt your files—your search might end here. Security researcher Mike Bautista at Cisco's Talos cyber intelligence unit have released a free decryption tool that makes it possible for victims infected with the PyLocky ransomware to unlock their encrypted files for free without paying any ransom. The decryption tool works for everyone, but it has a huge limitation—to successfully recover your files, you must have captured the initial network traffic (PCAP file) between the PyLocky ransomware and its command-and-control (C2) server, which generally nobody purposely does. This is because the outbound connection—when the ransomware communicates with its C2 server and submit decryption key related information—contains a string that includes both Initialization Vector (IV) and a password, which the ransomware generates randomly to encrypt the file

New Ransomware Spreading Rapidly in China Infected Over 100,000 PCs

New Ransomware Spreading Rapidly in China Infected Over 100,000 PCs
December 04, 2018Swati Khandelwal
A new piece of ransomware is spreading rapidly across China that has already infected more than 100,000 computers in the last four days as a result of a supply-chain attack... and the number of infected users is continuously increasing every hour. What's Interesting? Unlike almost every ransomware malware, the new virus doesn't demand ransom payments in Bitcoin. Instead, the attacker is asking victims to pay 110 yuan (nearly USD 16) in ransom through WeChat Pay—the payment feature offered by China's most popular messaging app. Ransomware + Password Stealer — Unlike WannaCry and NotPetya ransomware outbreaks that caused worldwide chaos last year, the new Chinese ransomware has been targeting only Chinese users. It also includes an additional ability to steal users' account passwords for Alipay, NetEase 163 email service, Baidu Cloud Disk, Jingdong (JD.com), Taobao, Tmall , AliWangWang, and QQ websites. A Supply Chain Attack — According to Chinese cybers

Romanian Police Arrest 5 People for Spreading CTB Locker and Cerber Ransomware

Romanian Police Arrest 5 People for Spreading CTB Locker and Cerber Ransomware
December 20, 2017Mohit Kumar
Romanian police have arrested five individuals suspected of infecting tens of thousands of computers across Europe and the United States in recent years by spreading two infamous ransomware families—Cerber and CTB Locker. Under Operation Bakovia —a major global police operation conducted by Europol, the FBI and law enforcement agencies from Romanian, Dutch, and the UK—raided six houses in East Romania and made five arrests, Europol said on Wednesday. Authorities have seized a significant amount of hard drives, external storage, laptops, cryptocurrency mining devices, numerous documents and hundreds of SIM cards during the raid. One thing to note is that all of the five suspects were not arrested for developing or maintaining the infamous ransomware strains, but for allegedly spreading CTB Locker and Cerber. Based on CryptoLocker, CTB Locker , aka Critroni, was the most widely spread ransomware families in 2016 and was the first ransomware to use the Tor anonymizing network

Warning: Two Dangerous Ransomware Are Back – Protect Your Computers
August 15, 2017Swati Khandelwal
Ransomware has been around for a few years but has become an albatross around everyone's neck—from big businesses and financial institutions to hospitals and individuals worldwide—with cyber criminals making millions of dollars. In just past few months, we saw a scary strain of ransomware attacks including WannaCry , Petya and LeakerLocker , which made chaos worldwide by shutting down hospitals, vehicle manufacturing, telecommunications, banks and many businesses. Before WannaCry and Petya , the infamous Mamba full-disk-encrypting ransomware and the Locky ransomware had made chaos across the world last year, and the bad news is—they are back with their new and more damaging variants than ever before. Diablo6: New Variant of Locky Ransomware First surfaced in early 2016, Locky has been one of the largest distributed ransomware infections, infecting organisations across the globe. By tricking victims into clicking on a malicious attachment, Locky ransomware encrypt

Ukrainian authorities have arrested a 51-year-old man accused of distributing the infamous Petya ransomware (Petya.A, also known as NotPetya) — the same computer virus that massively hit numerous businesses, organisations and banks in Ukraine as well as different parts of Europe around 45 days ago. However, the story is not as simple as it seems, which portrayed this man as a criminal. I recommend you to read complete article to understand the case better and then have an opinion accordingly. Sergey Neverov (Сергей Неверов), father of two sons and the resident of the southern city of Nikopol, is a video blogger and computer enthusiast who was arrested by the Ukrainian police on Monday, August 7 from his home. What Neverov Did? According to a press release published on Thursday by the Ukrainian cyber police department, Neverov uploaded a video, showing how to infect a computer with Petya.A ransomware—and also shared a download link for NotPetya malware to his social media

The cyber criminals behind the global WannaCry ransomware attack that caused chaos worldwide have finally cashed out their ransom payments. Nearly three months ago, the WannaCry ransomware shut down hospitals, telecom providers, and many businesses worldwide, infecting hundreds of thousands of computers in more than 150 countries, encrypting files and then charging victims $300-$600 for the keys. WannaCry was really bad, as the nasty ransomware forced the British NHS (National Health Service) to shut down hospitals and doctor's surgeries, and infected a Spanish telecommunications company and Russian mobile operator, among much more. Even a month after the outbreak, the WannaCry ransomware was found infecting systems at Honda Motor Company , forcing the factory to shut down its production, and 55 speed and traffic light cameras in Victoria, Australia. Overall, the hackers behind WannaCry made $140,000 in Bitcoins from the victims who paid for the decryption keys—but for

New Ransomware Threatens to Send Your Internet History & Private Pics to All Your Friends

After WannaCry and Petya ransomware outbreaks, a scary (but rather creative) new strain of ransomware is spreading via bogus apps on the Google Play Store, this time targeting Android mobile users. Dubbed LeakerLocker , the Android ransomware does not encrypt files on victim's device, unlike traditional ransomware, rather it secretly collects personal images, messages and browsing history and threatens to share it to their contacts if they don't pay $50 (£38). Researchers at security firm McAfee spotted the LeakerLocker ransomware in at least two apps — Booster & Cleaner Pro and Wallpapers Blur HD — in the Google Play Store, both of which have thousands of downloads. To evade detection of malicious functionality, the apps initially don't contain any malicious payload and typical function like legitimate apps. But once installed by users, the apps load malicious code from its command-and-control server, which instructs them to collect a vast number of sensitive

Petya Ransomware Spreading Rapidly Worldwide, Just Like WannaCry

Petya Ransomware Spreading Rapidly Worldwide, Just Like WannaCry
June 27, 2017Swati Khandelwal
Watch out, readers! It is ransomware, another WannaCry, another wide-spread attack. The WannaCry ransomware is not dead yet and another large scale ransomware attack is making chaos worldwide, shutting down computers at corporates, power supplies, and banks across Russia, Ukraine, Spain, France, UK, India, and Europe and demanding $300 in bitcoins. According to multiple sources, a new variant of Petya ransomware , also known as Petwrap, is spreading rapidly with the help of same Windows SMBv1 vulnerability that the WannaCry ransomware abused to infect 300,000 systems and servers worldwide in just 72 hours last month. Apart from this, many victims have also informed that Petya ransomware has also infected their patch systems. "Petya uses the NSA Eternalblue exploit but also spreads in internal networks with WMIC and PSEXEC. That's why patched systems can get hit." Mikko Hypponen  confirms , Chief Research Officer at F-Secure. Petya is a nasty piece of rans
