iPhone and iPad Hijacking: What You Need To Know

The past 24 hours has seen a spate of stories warning about a spate of ‘ransomware’ attacks on iPhones and iPads – especially in the the UK and Australia. According to the reports, compromised devices are locked and owners are instructed to email a ransom (variously: $100, $50, €100) to one “Oleg Pliss” to have their devices unlocked. These attacks aren’t really news. In fact, the Oleg Pliss scam appears to have been circulating for close to six months. However, it’s worthwhile reviewing what we do (and don’t) know about these latest attacks on mobile devices. Accordingly, Security Ledger has put together a short FAQ that tells you what you need to know about the latest mobile scam, and to dispel some of the rumors floating around in the Internet ether. What’s Going On? According to news reports and complaints on Apple Support forums, owners of iPhones and iPads are having their devices locked. […]

Akamai: New DoS Tool Leads To Resurgence of SNMP Attacks

The security firm Akamai issued an advisory to customers on Thursday warning that a new software tool for managing distributed denial of service (DDoS) attacks was leading to a resurgence in large-scale attacks that use Simple Network Management Protocol (SNMP) traffic to overwhelm web sites.   The Threat Advisory (reg wall) was issued by Akamai’s Prolexic Security Engineering and Response Team (or PLXsert). According to the advisory, Akamai began noticing a resurgence in DDoS attacks using SNMP on April 11. The company said that firms in industry verticals including consumer goods, gaming, online hosting and Software-as-a-Service and non-profits had all been targeted.   [Read more Security Ledger coverage of DDoS attacks here.] The company has identified new- and updated tools in the cyber underground, including one dubbed SNMP Reflector – that are enabling the attacks. Simple Network Management Protocol (SNMP) is a protocol that is used for managing devices on a network including […]

FireEye Report: Iranian Hacker Group Becoming More Sophisticated

A report from the security firm FireEye claims that hacking crews based in Iran have become more sophisticated in recent years. They are now linked to malicious software campaigns targeting western corporations and domestic actors who attempt to circumvent Internet filters put in place by the ruling regime.   The report, dubbed “Operation Saffron Rose,”(PDF)  was released on Tuesday. In a blog post accompanying the research, FireEye researchers say that it has identified a group of hackers it is calling the “Ajax Security Team” that appears to have emerged out of Iranian hacker forums such as Ashiyane and Shabgard. Once limited to website defacements, the Ajax team has graduated to malware-based espionage and other techniques associated with “advanced persistent threat” (APT) style actors, FireEye said. The researchers claim that the group has been observed using social engineering techniques to implant custom malware on victims’ computers. The group’s objectives seem to align with those […]

Blade Runner Redux: Do Embedded Systems Need A Time To Die?

The plot of the 1982 film Blade Runner (loosely based on the 1968 novel Do Androids Dream of Electric Sheep by Philip K Dick) turns on the question of what makes us ‘human.’ Is it memories? Pain? Our ability to feel empathy? Or is it merely the foreknowledge of our own certain demise? In that movie, a group of rebellious, human-like androids – or “replicants” – return to a ruined Earth to seek out their maker. Their objective: find a way to disable an programmed ‘end of life’ in each of them.  In essence: the replicants want to become immortal. It’s a cool idea. And the replicants – pre-loaded with fake memories and histories – pose an interesting philosophical question about what it is that makes us humans. Our artificial intelligence isn’t quite to the ‘replicant’ level yet (the fictional tale takes place in 2019, so we have time). But some […]

Heartbleed For Poets And Other Must-Reads

It’s H-Day + 2 – two full days since we learned that one of the pillars of online security, OpenSSL, has contained a gaping security hole for the past two years that rendered its protections illusory. As I wrote over on Veracode’s blog today: this one hurts. It exposes private encryption keys, allowing encrypted SSL sessions to be revealed. Trend Micro data suggests around 5% of one million Internet top-level domains are vulnerable.  IOActive notes that Heartbleed also appears to leave data such as user sessions subject to hijacking, exposes encrypted search queries and leaves passwords used to access online services subject to snooping, provided the service hasn’t updated their OpenSSL instance to the latest version. In fact, its safe to bet that the ramifications of Heartbleed will continue to be felt for months – even years to come. In the meantime, there is a lot of interesting coverage and […]
