Leading the latest edition of the ISMG Security Report: Secretary John Kelly's congressional testimony on how DHS led government efforts to mitigate the WannaCry ransomware attacks. Also, reports on ransomware defenses as well as big data and machine learning combining to secure IT.
The identity of the individual or group behind the global WannaCry ransomware campaign remains unclear. But whoever wrote the ransom notes appears to have been fluent in Chinese and pretty good at written English, according to a linguistic analysis from security firm Flashpoint.
In the wake of WannaCry, there's a critical new flaw in Samba, which provides Windows-based file and print services for Unix and Linux systems. Security experts say the flaw is trivial to exploit. US-CERT recommends immediate patching or workarounds.
A number of media reports have recently suggested there's a "link" between WannaCry and the Lazarus hacking group, implying that North Korea authorized the ransomware campaign. But based on the evidence available so far, it's much too early to attribute the attacks to anyone.
Target has reached a record settlement agreement with 47 states' attorneys general over its 2013 data breach. The breach resulted in hackers compromising 41 million customers' payment card details and contact details for more than 60 million customers being exposed.
The WannaCry ransomware outbreak was a huge "wake-up call" for the global information security community, says Dan Schiappa of Sophos. It's time to patch those legacy systems and prepare for the inevitable next big crimeware scare, he says.
Good news for many victims of WannaCry: Free tools developed by a trio of French security researchers can be used to decrypt some PCs that were forcibly encrypted by the ransomware, if the prime numbers used to build the crypto keys remain in Windows memory.
WannaCry ransomware victims who haven't backed up their files have a tough choice: take a risk paying the ransom or just accept the loss. But there's a slim glimmer of hope: French researchers have figured out a way to decrypt files without paying, although their tools won't work for everyone.
Reports on how the U.S. Congress is taking steps to toughen cybersecurity lead the latest edition of the ISMG Security Report. Also, an analysis of a Government Accountability Office study on the IoT landscape and the security threats facing the internet of things.
A series of email alerts from the Department of Health and Human Services about the WannaCry ransomware campaign - and a number of related daily conference calls with industry stakeholders - appear to be part of a ramped-up push to improve cyber information sharing in the healthcare sector.
Life after WannaCry: Already, other cybercrime gangs appear to be jumping on the SMB-targeting bandwagon, including the operators behind Uiwix ransomware. Thankfully, security experts say, these attacks pose scant risk.
The Shadow Brokers leaked spying tools - likely stolen from the National Security Agency - that aided WannaCry. But the hackers blame Microsoft and the U.S. government for the ransomware outbreak and are promising fresh exploits.
