Welcome to the The Week in Cybersecurity, which brings you the latest headlines from both the world and our team at ReversingLabs about the most pressing topics in cybersecurity. This week: International relations intersects with cybersecurity, learn how to leverage YARA rules, plus new developments on AstraLocker 2.0.

As tensions mount, NATO creates cyber rapid response
The war in Ukraine is well past the 100-day mark, and, like most other aspects of the conflict, the battlefront in the cyber conflict between the countries has shifted over time. As with its kinetic activities, Russia began its invasion with a 'shock and awe' campaign of cyber attacks. That included the hack of Viasat, a U.S. satellite communications firm used by Ukraine's military. It also included the release of a series of custom "wiper" malware programs, akin to the notorious NotPetya wiper that devastated Ukraine's public and private sector in 2017. (Check out our post from March on Hermeticwiper and Isaacwiper, two new wiper variants seen in the Ukraine conflict.)
Those initial forays were a mixed bag for Russia, which faltered badly in the early days of the war. Since then, however, the cyber component of the conflict has devolved into tit-for-tat attacks between Russia, Ukraine and even Ukraine's allies on both sides of the Atlantic. A report from Microsoft documented Russian cyber attacks on 128 organizations in 42 countries outside Ukraine in recent months, with the U.S., Poland, the Baltic nations, Denmark, Norway, Finland, Sweden and Turkey in Moscow's sites. In the meantime, hacking groups sympathetic with Ukraine launched attacks that delayed the St. Petersburg International Economic Forum, which some refer to as the Russian DAVOS. More recently, the Russian firm ROSCOSMOS was hacked after posting satellite images of NATO bases.
With cyber rapidly declaring itself as a full fledged domain of conflict, NATO is moving to solidify its role in countering Russian attacks on its members. As Politico reported, NATO members meeting in Madrid agreed to create a “virtual rapid response cyber capability” to counter Russian cyberattacks in Ukraine, That comes amid concerns that Moscow may target the United States and other NATO countries in retaliation for assistance to Ukraine. Under the new plan, NATO will act as a coordination platform for offering national assets to build and exercise a virtual rapid response cyber capability to respond to a serious cyber-attack. The United States will offer robust national capabilities as part of this support network, according to a statement on the summit released by the Whitehouse.

The stories we’re paying attention to this week
Cybersecurity Researchers Launch New Malware Hunting Tool YARAify (Infosecurity Group)
A group of security researchers from Abuse.ch and ThreatFox launched a new hub for scanning and hunting files. Dubbed YARAify, the defensive tool is designed to scan suspicious files against a large repository of YARA rules.YARAify (yaraify.abuse.ch) can scan files using public YARA rules and integrate both public and non-public YARA rules from Malpedia, which is operated by the Fraunhofer Institute in Germany.
Over 900K Kubernetes Instances Found Exposed Online (BleepingComputer)
Over 900,000 misconfigured Kubernetes clusters were found exposed on the Internet to potentially malicious scans, some even vulnerable to data-exposing cyberattacks.
Latest OpenSSL Version is Affected by a Remote Memory Corruption Flaw (Security Affairs)
Security expert Guido Vranken discovered a remote memory-corruption vulnerability in the recently released OpenSSL version 3.0.4. The library was released on June 21, 2022, and affects x64 systems with the AVX-512 instruction set.

In case you missed it
Here are the posts that went live this week from the ReversingLabs Blog and develop.secure.software.
ReversingLabs recently discovered instances of the AstraLocker 2.0 malware distributed directly from Microsoft Word files used in phishing attacks.
Not knowing what’s in your food can have consequences. The same is true for software. That’s why you need a software bill of materials (SBOM) to minimize software security risk.
Should you use GitHub Copilot? “No,” say open-source fans. “Heck no,” say lawyers. “Yeah,” say the sort of devs who do Stack Exchange copypasta without a second thought.
