Evilnum Cyberspies Update Arsenal in Recent Attacks

The threat group tracked as Evilnum was observed using updated tactics and tools in recent attacks, Cybereason's Nocturnus research team reported last week.

How to protect yourself from the hidden threat of evasive scripts

Evasion techniques are used by cybercriminals to evade detection, and they are especially prevalent in the context of scripts, which on their own have legitimate uses (e.g., to automate processes on a computer system). Unfortunately, scripts can also be used for malicious purposes, and malicious scripts are unlikely to be detected or blocked by the average antimalware solution. That's why cybercriminals are turning to script-based attacks and other evasive malware - like Emotet - more often than ever before. READ MORE...


Securing Active Directory accounts against password-based attacks

Traditional password-based security might be headed for extinction, but that moment is still far off. In the meantime, most of us need something to prevent our worst instincts when it comes to choosing passwords: using personal information, predictable (e.g., sequential) keystroke patterns, password variations, well-known substitutions, single words from a dictionary and - above all - reusing the same password for many different private and enterprise accounts. What does a modern password policy look like? READ MORE...

Online voting vendor Voatz urges Supreme Court to limit security research

Unauthorized security research can "cause harmful effects," Voatz says in baffling brief. The Supreme Court is considering whether to adopt a broad reading of the Computer Fraud and Abuse Act that critics say could criminalize some types of independent security research and create legal uncertainty for many security researchers. Voatz, an online voting vendor whose software was used by West Virginia for overseas military voters in the 2018 election, argues that this wouldn't be a problem. READ MORE...


Critical Vulnerabilities Expose MoFi Routers to Remote Attacks

Routers made by MoFi Network are affected by several vulnerabilities, including critical flaws that can be exploited to remotely hack a device. The vulnerabilities were reported to the vendor in May by Rich Mirch, a security researcher at CRITICALSTART. However, some of them remain unpatched. The researcher discovered a total of 10 vulnerabilities affecting MOFI4500 routers, a majority related to the web management interface, which by default is accessible on all network interfaces.

Encryption

Popular Android apps are rife with cryptographic vulnerabilities

Columbia University researchers have released Crylogger, an open source dynamic analysis tool that shows which Android apps feature cryptographic vulnerabilities. They also used it to test 1780 popular Android apps from the Google Play Store, and the results were abysmal. Each of the tested apps with an instrumented crypto library were run in Crylogger, which logs the parameters that are passed to the crypto APIs during the execution and then checks their legitimacy offline by using a list of crypto rules.

How the government is keeping hackers from disrupting coronavirus vaccine research

Six months ago, as professional sports were postponed indefinitely, schools were shuttering, Tom Hanks was the poster boy for COVID-19, and President Donald Trump addressed a nervous nation, people at the highest levels of the U.S. government became laser-focused on one idea: Coronavirus vaccine research needed to be defended from hacking attempts. Soon after the World Health Organization declared a pandemic, the Pentagon's Defense Digital Service and the National Security Agency got to work on a behind-the-scenes protection mission READ MORE...
