Microservices architecture is forcing developers to not only rethink how they design and develop applications, but also common security assumptions and practices. With the decomposition of traditional applications, each microservice instance represents a unique network endpoint, creating a distributed attack surface that is no longer limited to a few isolated servers or IP addresses.

Red Cross Asks Disaster-Area Residents to Unlock WiFi Networks (August 25, 2016)Rescue workers at the earthquake site in Italy have asked local residents to disable passwords from their wi-fi networks to help rescuers and aid workers communicate.
[Editor Comments ]
The desire to help should be complemented with taking precautions. Opening your wifi for use by aid organizations should be preceded by disabling wifi on all of your devices. Desperate times brings out the best and worst in people and some small number will be out for opportunity.
Seems harsh to say, but I think it is pretty clear that the long term negatives of this would outweigh the short term positives. I'm a ham radio operator (K3TN); there are already emergency communications frequencies reserved for supporting the disaster recovery effort in Italy and hams have proven ways of bringing in temporary communications capabilities for recovery and relief workers that don't require compromises in security.
Nice use of an existing infrastructure. Sure, many will never re-enable the password, and leave their networks exposed. But security is also about availability and in this case, it is possible that these wifi networks will help rescuers better communicate and save lives.
In a disaster, the biggest problem is always communication. The bridge collapse in Minneapolis is a textbook case of wireless helping rescue and recovery operations: htps://en.wikipedia.org/wiki/Minneapolis_wireless_internet_network But wireless home networks do more than that, they give location information. In the past 20 years with GPS and mapping of SSID locations, paper maps are becoming pretty scarce:

Apple Updates iOS to Fix Trident Vulnerabilities (August 25, 2016)Apple has updated its iOS mobile operating system to version 9.3.5 to address three critical vulnerabilities that could be exploited to install spyware and steal private information from apps. The exploit, known as Trident, remotely jailbreaks vulnerable devices without the user's knowledge. It then installs the spyware, known as Pegasus, which can harvest a plethora of personal data, including messages, emails, social medias posts, and wi-fi passwords. The issue was detected when it was used against a device belonging to a human rights activist.
[Editor Comments ]
These vulnerabilities are serious and those with MDM should force an update before allowing iOS devices to connect to their networks. However, these vulnerabilities are at least being patched - which is more than we can say for most Android handsets when vulnerabilities are announced.
While Apple does not pre-announce patches, this is as close as Apple has gotten to a "surprise" patch for iOS. It also shows, yet again, how each time such an exploit is used, there is a risk of it being discovered by the target. In this case, luckily, the target shared it with others (and in the end Apple) to help fix the problem. But as soon as an exploit like this becomes known, it will be used against lower value targets, as well. "Collateral Damage" no longer requires physical proximity to the target, and can extend in time well beyond the original attack.
"If you see something, say something." This attack and the exploited vulnerabilities were discovered because a target was suspicious of a bait message.

French Submarine Builder DCNS Designs Leaked (August 24, 2016)Documents leaked from French manufacturer DCNS contain information about Scorpene-class submarines, which are used by India's military. India has launched an investigation. The vessels are also used by Malaysia and Chile. Australia, which also has vessels built by DCNS, says that the leaked information does not pertain to their submarines.
[Editor Comments ]
I hope no one believed that only US weapon programs lost sensitive information at the hands of cyber spies? The importance and performance of modern submarines makes undersea warfare a highly competitive enterprise.
Earlier this year, I blogged about Australia making the decision to hand carry their submarine plans to suppliers after making a risk assessment. Presumably they determined that there were no effective compensating controls to keep the plans safe given the sensitivity of the data. Today, I expect that the Australian officials involved in this decision are content in their decision.

Cisco Patching ASA Flaw Against Leaked Exploit (August 25, 2016)Cisco has released patches for a vulnerability in its Adaptive Security Appliance (ASA) firewalls that are used in an exploit in the trove of leaked tools linked to the NSA. The exploit, known as ExtraBacon, takes advantage of a buffer overflow vulnerability in the Simple Network Management protocol (SNMP) implementation in Cisco's ASA software.
[Editor Comments ]
In order for the EXTRABACON vulnerability to be successful, the attacker must be able to talk to a port that has SNMP enabled. Those following best practices have disabled SNMP on external interfaces and control SNMP access via ACLs and are largely protected from exploitation. Infosec researchers have ported the EXTRABACON vulnerability to later versions of the Cisco IOS than were originally supported (including 9.2(4)) (
I'd also like to hear details of Cisco, Juniper and Fortinet "patching" their SDLC processes that allowed such vulnerabilities in their products to exist for so long. If they did run software vulnerability assessment tools but those products didn't find things like buffer overflows in SNMP code, I'd also like to hear those tool vendors announce fixes to their products.

[Editor Comments ]
OK, I think everyone hates pop-up ads (they actually sound even more ominous and creepy when called "intrusive interstitials"...) and especially on our smart phones. Still, I get this queasy feeling when the dominant advertising supported search engine says "we will punish web sites that don't do advertising the way Google says it should be done." From a security point of view, I worry about forcing advertising to be more integrated into legitimate content, which is where this is heading. That is great for click through rates, which means more revenue for advertising networks like Google, but also increases the risks of malvertising.

Decryption Key Available for Wildfire Ransomware (August 24, 2016)Researchers have developed and made available a tool to decrypt files that have been locked by Wildfire ransomware. The attackers using the ransomware demand payment of 1.5 bitcoin to decrypt the files. Wildfire has targeted users mainly in the Netherlands and Belgium by pretending to be missed package delivery notifications. The free decryption tool was released through the No More Ransom initiative, a collaborative effort of Europol, the Dutch National Police, Intel Security, and Kaspersky Lab. The initiative offers keys for other strains of ransomware as well.
[Editor Comments ]
The efforts by government and private firms to assist victims in these types of cases is laudable and absolutely appreciated. Nevertheless, being provided the "antidote" after being poisoned is not a long-term solution. Using these same collaborative actions between public and private organizations to identify and stop the perpetrators, as well as raising awareness so people better protect their networks, can enhance this effort.

Swiss Authorities Indict Three in Phishing Case (August 23 and 24, 2016)Authorities in Switzerland have indicted three people in connection with a phishing scheme. The people allegedly stole payment card information from more than 130,000 people between October 2009 and their arrests in 2014 and 2015. They suspects were arrested in Bangkok and extradited to Switzerland. The case marks the country's first indictment in a global phishing case.]

Congressman Pushing for Cell Phone System Vulnerability Investigation (August 24, 2016)US Representative Ted Lieu (D-California) is urging the Federal Communications Commission (FCC) to expedite its investigation of the vulnerability in the Signaling System Number 7 (SS7) protocol used in mobile phone networks. Lieu wrote, "In light of the recent cyber hack at the DCCC that" exposed cell phone numbers of Democratic members of Congress, "the SS7 problem is no longer a theoretical threat."

Russian Banks Face Stronger Security Rules (August 22, 2016)The Russian Central Bank has established mandatory cybersecurity rules for domestic Russian banks. The banks will be required to report breaches to FinCERT, and to constantly monitor computers that transfer payments to the Central bank. Banks that are not compliant with the rules by the end of June 2017 could face penalties, including fines and being disconnected from the electronic payments system.
[Editor Comments ]
They are requiring the completion of sensitive transactions or the exercise of special privileges to rely upon actions of multiple independent parties. This is a test that all central banks and other regulators should apply.
