YK: kyberiskuissa roimaa kasvua supervalta boikotoi kokousta

www.tivi.fi/uutiset/tv/b9faeb00-ec81-42a1-ba54-18f88164034f YK varoitti perjantaina kyberrikosten olevan kasvussa koronapandemian aikana. YK:n epävirallisessa turvallisuusneuvoston kokouksessa perjantaina puhunut alemman tason apulaispääsihteeri Izumi Nakamitsu sanoi, että kriisi on johdattanut maailmaa kohti teknologista innovointia ja verkon kautta tehtävää yhteistyötä. Samalla hän sanoi kentältä kuuluvan huolestuttavia uutisia: kyberiskuja on suunnattu terveydenhoidon organisaatioita ja lääketieteellisiä tutkimuslaitoksia vastaan ympäri maailmaa. Haittasähköpostien määrissä on nähty 600 prosenttia kasvua. Etätöihin siirtymisen aikakaudella lisääntynyt riippuvuus verkkopalveluista on samalla lisännyt myös organisaatioiden haavoittuvuutta verkkohyökkäyksille. Arvion mukaan joku joutuu iskun uhriksi joka 39 sekunti. Lue myös:

Do Androids dream of equal security?

blog.f-secure.com/android-security/ Several pieces of research published by F-Secure Labs demonstrate that region-specific default configurations and settings in some flagship Android devices are creating security problems that affect people in some countries but not others. According to F-Secure Consulting’s UK Director of Research James Loureiro, the research highlights the security compromises vendors can inadvertently make when customizing Android builds. Read also:

16-30 April 2020 Cyber Attacks Timeline

www.hackmageddon.com/2020/05/26/16-30-april-2020-cyber-attacks-timeline/ It’s time to publish the second timeline of April, covering the main cyber attacks occurred between April 16 and April 30 (including three events occurred in the first half of the same month. Due to the COVID-19 crisis, the level of activity continues to be quite high. In this timeline I have collected 92 events, less than the 104 events collected in the first timeline of April, but equally an important number. So the pandemic continues to characterize the threat landscape, nearly one quarter of the events is somehow related to COVID-19: we have seen opportunistic phishing campaigns exploiting the fear, but also targeted cyber espionage operations against institutions involved in the fight against the virus.

Automating your.apk reverse engineering workflow

medium.com/ouspg/automating-your-apk-reverse-engineering-workflow-95604e096402 Lets say I’m handed an encoded.zip containing a malicious.apk file. My typical workflow would consist of unzipping the file (the password most commonly is “infected”). Generating a hash of it to search if previous analysis exists and whether it is found in VirusTotal. Then I want to see the unobfuscated AndroidManifest.xml which will at the very least tell me the permissions the application requests. Finally I want to see the source code the.apk was compiled from.

Why Is 3sYqo15hiL Such A Popular Password?

www.forbes.com/sites/daveywinder/2020/05/25/why-is-3syqo15hil-such-a-popular-password-lets-mark-that-mystery-solved-cybersecurity-advice-password-manager/#5156d9d550a0 3sYqo15hiL was, the analysis revealed, the 21st most used password within this breach data. Which begs the question, why the heck is that? Luckily, the people at Passlo who performed the FTSE100 data breach analysis had the answer. It appears that 3sYqo15hiL is linked to email addresses used for spamming purposes. In other words, it’s a common password being applied by a spam bot network that uses free email providers. This doesn’t, however, explain why it turns up in emails within the domain of such a large and reputable financial company as Standard Chartered.

Spike in Credential Leaks for the Pharmaceutical and Biotech Industry

www.recordedfuture.com/pharmaceutical-biotech-credential-leaks/ Recorded Future noted a spike in the relative number of credential leaks from the pharmaceutical and biotechnology sector compared to all credential leaks between November of 2019 and March of 2020.

Thai Database Leaks 8.3 Billion Internet Records

rainbowtabl.es/2020/05/25/thai-database-leaks-internet-records/ I recently discovered an exposed ElasticSearch database when browsing BinaryEdge and Shodan. This database appears to be controlled by a subsidiary of a major Thailand-based mobile network operator named Advanced Info Service (AIS). According to Wikipedia, AIS is “Thailand’s largest GSM mobile phone operator with 39.87 million customers” as of 2016. The database was likely controlled by AIS subsidiary Advanced Wireless Network (AWN). It contained a combination of DNS query logs and NetFlow logs for what appears to be AWN customers. Using this data it is quite simple to paint a picture of what a person does on the Internet. I made multiple attempts to contact AIS to get the database secured without success. At that point I contacted Zack Whittaker a journalist from TechCrunch for assistance. We were still unable to make contact with AIS. I then contacted the Thailand National CERT team (ThaiCERT). ThaiCERT who was able to make contact with AIS, and we were successful in getting the database secured.
