With Multi-Vector Attacks, Quality Threat Intelligence Matters

December 23, 2014 Scott Harrell

In the last year, the world’s attention has been riveted by a series of high-profile hacks of major corporations in retail, finance and the entertainment industry, among others. Each of these incidents is unique, involving different threat actors and motives. However, each of these attacks is also a sterling example of what we, at Cisco, term “multi-vector attack” that employs a range of technologies, deployed in numerous stages, to penetrate the defenses of the target organization. Here at Cisco, we have studied these attacks in-depth and have identified some commonalities among these multi-vector attack, and useful approaches to combat them. This blog post will discuss some of our findings. About Multi-Vector Attacks Any cyber attack, large or small is born from a weak link in the security chain. These weak links take many forms: poorly configured Web servers, gullible employees or vulnerable-but-common applications like Microsoft Office, Adobe Reader and Java are common examples. Multi-vector attacks […]

U.S. Weather Systems Victims of Cyber Attack

November 12, 2014 Paul Roberts

The Washington Post is reporting that hackers from China breached the network of the National Oceanic and Atmospheric Administration (NOAA) in September, forcing cyber security teams to seal off data vital to disaster planning, aviation, shipping and scores of other crucial uses. The article cites sources within the government and Congress. The intrusion occurred in late September. However, NOAA officials gave no indication that they had a problem until Oct. 20, according to three people familiar with the hack and the subsequent reaction by NOAA, which includes the National Weather Service. According to the report, NOAA officials believe that actors based in China are responsible for the attack. The report also claims that efforts to respond to it resulted in an interruption in some key services, including NOAA’s National Ice Center Web Site, a partnership with the U.S. Navy and U.S. Coast Guard to monitor conditions for navigation. That two-day outage skewed the accuracy […]

Dusting For Malware’s Bloody Prints

October 25, 2014 Paul Roberts

Malicious software is nothing new. Computer viruses and worms have been around for decades, as have most other families of malware like remote access tools (RATs) and key loggers. But all our experience with malware hasn’t made the job of knowing when our organization has been hit by it any easier. In fact, recent news stories about breaches at Home Depot, Target, Staples and other organizations makes it clear that even sophisticated and wealthy corporations can easily overlook both the initial compromise and endemic malware infections – and at great cost. That may be why phrases like “dwell time” or “time to discovery” seem to pop up again and again in discussions of breach response. There’s no longer any shame in getting “popped.” The shame is in not knowing that it happened. Greg Hoglund says he has a fix for that latter problem. His new company, Outlier Security, isn’t “next generation […]

Europol Warns of Internet of Things Risk

October 6, 2014 Paul Roberts

In a newly released report, Europol’s European Cybercrime Center (EC3) warns that the growth of the Internet of Things (IoT) threatens to strengthen the hand of organized cyber criminal groups and make life much more difficult for police and governments that wish to pursue them. EC3’s latest Internet Organized Crime Threat Assessment (iOCTA) says the “Internet of Everything” will greatly complicate the work of law enforcement creating “new opportunities for everything from cyber criminals to state actors to child abusers. The growing numbers of connected devices will greatly expand the “attack surface” available for cyber criminal activity, the EC3 warns. Cyber criminals may co-opt connected devices for use in common criminal activity (like denial of service attacks and spam campaigns). However, advancements like connected (“smart”) vehicles and infrastructure create openings for large scale and disruptive attacks. The report, which was published late last months, is a high level position paper and pulls data mostly […]

Report: Hacked Password Behind Compromise of 75m JPMorgan Accounts

October 3, 2014 Paul Roberts

The top news this week is about Wall Street giant JP Morgan Chase, which disclosed on Thursday that a previously disclosed breach was much larger than initially believed, affecting more than 75 million account holders. And once again, reports suggest that a compromised employee account may be at the root of the incident. Bloomberg, which first broke the news of the cyber attack on JPMorgan Chase in August, said on Friday that hackers exploited an employee’s access to a development server as part of an attack on a JPMorgan Chase & Co. server that led to one of the largest cyber-attacks ever and the theft of data on 76 million households and 7 million small businesses. According to the Bloomberg report, which cited “people familiar with the bank’s review,” the breach started in June when an employee’s user name and password for what’s described as “a web-development server” were compromised. From that […]
