Privacy and human rights advocates, technology companies, and trade associations have today called on U.S. political leaders to reform the country’s surveillance laws. We add our voice to those calls. These reforms will help show the world that the U.S. Government is ready to lead the dialogue on global standards of conduct, and wants to further build international trust with citizens – a cornerstone for our industry.
We also see a need for governments to agree on transparent standards of conduct. Building a system with appropriate safeguards and limits will serve both national security objectives and the needs of global commerce. In May 2014, Cisco offered a series of recommendations that support customer confidence in the global internet economy, while respecting the role that governments need to play in ensuring the physical safety and the economic security of their citizens. Governments and industry players need to deliver these outcomes for our future. Cisco is ready to play our part and we believe our peers and colleagues in industry and government are as well.

This blog post was authored by Troy Fridley and Omar Santos of Cisco PSIRT.
On Mar 9 2015, the Project Zero team at Google revealed findings from new research related to the known issue in the DDR3 Memory specification referred to as “Row Hammer”. Row Hammer is an industry-wide issue that has been discussed publicly since (at least) 2012.
The new research by Google shows that these types of errors can be introduced in a predictable manner. A proof-of-concept (POC) exploit that runs on the Linux operating system has been released. Successful exploitation leverages the predictability of these Row Hammer errors to modify memory of an affected device. An authenticated, local attacker with the ability to execute code on the affected system could elevate their privileges to that of a super user or “root” account. This is also known as Ring 0. Programs that run in Ring 0 can modify anything on the affected system. Read More »

In February, Cisco Managed Threat Defense (MTD) security investigators detected a rash of Dridex credential-stealing malware delivered via Microsoft Office macros. It’s effective, and the lures appear targeted at those responsible for handling purchase orders and invoices. Here’s a breakdown of the types of emails we’ve observed phishing employees and inserting trojans into user devices.
