Cybersecurity researchers from ESET on Thursday said they took down a portion of a malware botnet comprising at least 35,000 compromised Windows systems that attackers were secretly using to mine Monero cryptocurrency. The botnet, named "VictoryGate," has been active since May 2019, with infections mainly reported in Latin America, particularly Peru accounting for 90% of the compromised devices. "The main activity of the botnet is mining Monero cryptocurrency," ESET said . "The victims include organizations in both public and private sectors, including financial institutions." ESET said it worked with dynamic DNS provider No-IP to take down the malicious command-and-control (C2) servers and that it set up fake domains (aka sinkholes) to monitor the botnet's activity. The sinkhole data shows that between 2,000 and 3,500 infected computers connected to the C2 servers on a daily basis during February and March this year. According to ESET res...

Cybersecurity researchers have spotted a new variant of the Snatch ransomware that first reboots infected Windows computers into Safe Mode and only then encrypts victims' files to avoid antivirus detection. Unlike traditional malware, the new Snatch ransomware chooses to run in Safe Mode because in the diagnostic mode Windows operating system starts with a minimal set of drivers and services without loading most of the third-party startup programs, including antivirus software. Snatch has been active since at least the summer of 2018, but SophosLabs researchers spotted the Safe Mode enhancement to this ransomware strain only in recent cyber attacks against various entities they investigated. "SophosLabs researchers have been investigating an ongoing series of ransomware attacks in which the ransomware executable forces the Windows machine to reboot into Safe Mode before beginning the encryption process," the researchers say . "The ransomware, which calls it...

Every week seems to bring news of another data breach, and it's no surprise why: securing sensitive data has become harder than ever. And it's not just because companies are dealing with orders of magnitude more data. Data flows and user roles are constantly shifting, and data is stored across multiple technologies and cloud environments. Not to mention, compliance requirements are only getting stricter and more elaborate.  The problem is that while the data landscape has evolved rapidly, the usual strategies for securing that data are stuck in the past. Gone are the days when data lived in predictable places, with access controlled by a chosen few. Today, practically every department in the business needs to use customer data, and AI adoption means huge datasets, and a constant flux of permissions, use cases, and tools. Security teams are struggling to implement effective strategies for securing sensitive data, and a new crop of tools, called data security platforms, have appear...

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 ...

There has been no shortage of massive security breaches so far this year. Just last July, Capital One disclosed that it was hit by a breach that affected more than 100 million customers. Also recently, researchers came across an unsecured cloud server that contained the names, phone numbers, and financial information of virtually all citizens of Ecuador – around 20 million people . These are just the latest in a long line of security breaches affecting enterprises over the past few years. The Yahoo!, Equifax, and Marriott hacks and Facebook's scandal should still be fresh in people's memories, reminding everyone that even large corporations with budgets for enterprise cybersecurity may not be secure enough to protect customer information. These records are now out there, stored in hackers' data dumps , and are potentially tradable over the Dark Web. The availability of such information online increases a person's risk of being victimized through fraud and iden...

Cases of document-based malware are steadily rising. 59 percent of all malicious files detected in the first quarter of 2019 were contained in documents. Due to how work is done in today's offices and workplaces, companies are among those commonly affected by file-based attacks. Since small to medium businesses (SMBs) usually lack the kind of security that protects their larger counterparts, they have a greater risk of being affected. Falling victim to file-based malware can cause enormous problems for SMBs. An attack can damage critical data stored in the organization's computers. Such loss can force a company to temporarily halt operations, resulting in financial losses. If a customer's private and financial information is compromised, the company may also face compliance inquiries and lawsuits. Their reputations could also take a hit, discouraging customers from doing business with them. But despite these risks, SMBs still invest very little in cybersecurity...

In an effort to combat cyberterrorism in Brazil, Panda Security has signed an agreement to support the training of the Brazilian Army's operational agents. These agents are engaged in the battle against internet-based crime and strategic intervention for cyber warfare. Panda Security will also provide endpoint protection for 37,500 computers belonging to the Army's Military Commands. This protection aims to counter malware, targeted attacks, and web threats. Panda's anti-malware lab, PandaLabs, will collaborate with the Army's Cyber-Warfare Communication Center to train individuals involved in the scientific and forensic investigation of cybercrime. The partnership will include the exchange of malware samples, with Panda providing rapid response and classification of malicious codes impacting Brazil. Brig. Gen. Antonino dos Santos Guerra Neto stated that Brazil has approximately 60,000 computers, experiencing an average of 100 probes daily across its 12 IT c...
