WanaCrypt0r Hits Worldwide

Consumers and businesses should be sure their Windows systems and software are updated with all current patches in order to stop the spread of this dangerous ransomware attack.

Reports of two massive, global ransomware attacks are dominating the news. As workers in Europe are heading home for the weekend, ransomware is shutting down their systems. Here’s what we know so far.

Big targets
National Health Service (NHS) England, and Telefonica, one of the largest telecom providers in the world, have each given out statements indicating that their systems have been brought to a grinding halt by a ransomware that Malwarebytes detects as Ransom.WanaCrypt0r. The ransomware has also been observed hitting companies in Spain, Russia, Ukraine, and Taiwan.

Method
The ransomware is spread using a known, and patched, vulnerability (MS17-010) that came from a leaked NSA set of exploits that we reported on our blog in April. Our research shows the encryption is done with RSA-2048 encryption. That means that decryption will be next to impossible, unless the coders have made a mistake that we haven’t found yet.

The demanded ransom of $300 and the potential risks to the public that come with the targets being big utility and healthcare companies seem to be in shrill contrast. We can only hope that the companies that were hit will be able to get their backups deployed quickly and can start the recovery from this cyberattack. 

Protection
Consumers and businesses alike should be sure their systems and software are updated with all current patches in order to stop the spread of infection. We’ll continue to update this post as news develops and provide additional technical analysis throughout the day.

Server crash or files encrypted?
Either way, when a server fails, when drives fail, when they become unreadable, any company - any Technology professional SHOULD have a solid, tested backup and restore solution on hand.  This is just common sense folks.  A few years ago one of my small 501C3 accounts got destroyed by ransomware and I had a solid restore plan in place, within 3 hours all data was restored to server and workstation.  FOLKS - BACKUP AND REST!!!

Enterprise Vulnerabilities
From DHS/US-CERT's National Vulnerability Database
CVE-2017-9317
PUBLISHED: 2018-05-23
Privilege escalation vulnerability found in some Dahua IP devices. Attacker in possession of low privilege account can gain access to credential information of high privilege account and further obtain device information or attack the device.
CVE-2018-1193
PUBLISHED: 2018-05-23
Cloud Foundry routing-release, versions prior to 0.175.0, lacks sanitization for user-provided X-Forwarded-Proto headers. A remote user can set the X-Forwarded-Proto header in a request to potentially bypass an application requirement to only respond over secure connections.
CVE-2018-1122
PUBLISHED: 2018-05-23
procps-ng before version 3.3.15 is vulnerable to a local privilege escalation in top. If a user runs top with HOME unset in an attacker-controlled directory, the attacker could achieve privilege escalation by exploiting one of several vulnerabilities in the config_file() function.
CVE-2018-1123
PUBLISHED: 2018-05-23
procps-ng before version 3.3.15 is vulnerable to a denial of service in ps via mmap buffer overflow. Inbuilt protection in ps maps a guard page at the end of the overflowed buffer, ensuring that the impact of this flaw is limited to a crash (temporary denial of service).
CVE-2018-1125
PUBLISHED: 2018-05-23
procps-ng before version 3.3.15 is vulnerable to a stack buffer overflow in pgrep. This vulnerability is mitigated by FORTIFY, as it involves strncat() to a stack-allocated string. When pgrep is compiled with FORTIFY (as on Red Hat Enterprise Linux and Fedora), the impact is limited to a crash.
