Iranian government-sponsored advanced persistent threat (APT) actors are exploiting known Microsoft and Fortinet vulnerabilities to attack targets with ransomware in the transportation, healthcare and public health sectors, according to an alert issued on Nov. 17 by the Cybersecurity and Infrastructure Security Agency (CISA).
A recently published report from the US Government Accountability Office (GAO) has warned that official security guidance from the Department of Education is out-of-date, and needs to be refreshed to address the increasing reports of ransomware and other cyber threats.
The number of ransomware attacks continues to grow, and that trend will likely continue in 2022. Organizations will be attacked, files will be encrypted, and victims will need to decide whether to pay ransom or try to implement expensive and painful recovery techniques on their own. That much, unfortunately, should come as no surprise, but what will be different is how those attacks are carried out.
FIN7 is a well-organized criminal group composed of highly-skilled individuals that target financial institutions, hospitality, restaurant, and gambling industries. Until recently, it was known that high-level individuals of this criminal enterprise were arrested — specifically 3 of them — and extradited to the United States. This criminal group performed highly technical malicious campaigns which included effective compromise, exfiltration and fraud using stolen payment cards.
In the second half of 2021 the AT&T Managed Threat Detection and Response (MTDR) security operations center (SOC) observed an increasing number of attacks against vulnerable Exchange servers. A number of these attacks were attempting to leverage proxyshell vulnerability to gain access to customer’s networks.
Today’s cyber threat landscape is extremely challenging. Ransom this, ransom that, ransom everywhere – information technology (IT) professionals must work to protect organizations against the next big ransomware attack. Over the years, the sophistication of ransomware attacks has increased as well as the amount of money demanded and paid out in exchange for the ransom-held information.
On November 1st, 2021, a public disclosure of a paper titled Trojan Source: Invisible Vulnerabilities described how malicious actors may employ unicode-based bidirectional control characters to slip malicious source code into an otherwise benign codebase. This attack relies on reviewers confusing the obfuscated malicious source code with comments.
Supply-chain attacks may not grab the headlines in the same way as ransomware or data breaches, but these sneaky cyberattacks are just as dangerous for your business.
A keylogger is a type of spyware that monitors and records user keystrokes. They allow cybercriminals to read anything a victim is typing into their keyboard, including private data like passwords, account numbers, and credit card numbers. Some forms of keyloggers can do more than steal keyboard strokes. They can read data copied to the clipboard and take screenshots of the user's screen - on PCs, Macs, iPhones, and Android devices. Keyloggers are not always the sole threat in cyberattacks.
