Attackers Taking Advantage of the Coronavirus/COVID-19 Media Frenzy

www.fortinet.com/blog/threat-research/attackers-taking-advantage-of-the-coronavirus-covid-19-media-frenzy.html Over the past several weeks, FortiGuard Labs has been observing a significant increase in both legitimate and malicious activity surrounding the Coronavirus.. Threat findings via OSINT channels have yielded multiple themes, such as those appearing to be reports from trusted sources, such as governmental agencies, news outlets, etc. but that were actually malicious. It is also important to note that we are likely only scratching the surface on observable attacks as this is a global outbreak, and most of our observations have been in English or languages . The issue has now become so problematic that the World Health Organization (WHO) recently issued a statement on their website titled, Beware of criminals pretending to be WHO. The UN also recently added an advisory on the 29th of February as well reminding citizens to be vigilant of such scams.. also:


Enable that MF-ing MFA: 1.2 million Azure Active Directory accounts compromised every month, reckons Microsoft

www.theregister.co.uk/2020/03/05/microsoft_12_million_enterprise_accounts_are_compromised_every_month/ Microsoft reckons 0.5 per cent of Azure Active Directory accounts as used by Office 365 are compromised every month.. “About a half of a per cent of the enterprise accounts on our system will be compromised every month, which is a really high number. If you have an organisation of 10,000 users, 50 will be compromised each month,” said Weinert.. The key point, though, is that if an account is compromised, said Weinert, “there’s a 99.9 per cent chance that it did not have MFA [Multi Factor Authentication]”. MFA is where at least one additional identifier is required when logging in, such as a code on an authenticator application or a text message to a mobile phone.

Intel x86 Root of Trust: loss of trust

blog.ptsecurity.com/2020/03/intelx86-root-of-trust-loss-of-trust.html The scenario that Intel system architects, engineers, and security specialists perhaps feared most is now a reality. A vulnerability has been found in the ROM of the Intel Converged Security and Management Engine (CSME). This vulnerability jeopardizes everything Intel has done to build the root of trust and lay a solid security foundation on the company’s platforms.. The problem is not only that it is impossible to fix firmware errors that are hard-coded in the Mask ROM of microprocessors and chipsets. The larger worry is that, because this vulnerability allows a compromise at the hardware level, it destroys the chain of trust for the platform as a whole.

Mokes and Buerak distributed under the guise of security certificates

securelist.com/mokes-and-buerak-distributed-under-the-guise-of-security-certificates/96324/ The technique of distributing malware under the guise of legitimate software updates is not new. As a rule, cybercriminals invite potential victims to install a new version of a browser or Adobe Flash Player. However, we recently discovered a new approach to this well-known method: visitors to infected sites were informed that some kind of security certificate had expired. Unsurprisingly, the . We detected the infection on variously themed websites from a zoo to a store selling auto parts. The earliest infections found date back to January 16, 2020.

Email domains without DMARC enforcement spoofed nearly 4X as often

www.helpnetsecurity.com/2020/03/05/dmarc-records/ As of January 2020, nearly 1 million (933,973) domains have published DMARC records an increase of 70% compared to last year, and more than 180% growth in the last two years.. However, just 13% of all DMARC records are configured with enforcement policies, demonstrating that interest in DMARC is increasing but DMARC expertise is not keeping pace.. But publishing a DMARC record is just the first step enforcement must be reached before a domain is protected, and trust can be restored to email.. Theres an additional downside to not getting to enforcement: Our research demonstrates that domains without DMARC policies at enforcement are spoofed nearly four times more often compared to domains with DMARC at enforcement. This is because fraudsters give up trying to spoof a domain once they realize it doesnt work, and move on to easier targets.

Warning: An Android Security App With 1 Billion Downloads Is Recording Users Web Browsing

Amongst those was an app called Clean Master, a security tool promising antivirus protection and private browsing. It had more than 1 billion installs before it was evicted and, despite Googles ban, is one of Androids most downloaded apps ever and is likely still running on millions of phones.. Whilst Google hasnt commented on what it knew about the app, created by Chinas Cheetah Mobile, Forbes has learned a security company provided the tech giant with evidence the tool was collecting all manner of private Web use data.. That includes which websites users visited from the in-app private browser, their search engine queries and their Wi-Fi access point names, right down to more detailed information like how they scrolled on visited Web pages, according to the security companys researcher, who also provided the information to Forbes.
