Generative AI Can Clone and Modify Android Apps for as Little as 88 Kopecks, Positive Technologies Warns
Specialists at Positive Technologies have shown that modern generative AI systems can rapidly create functional clones of Android applications at minimal cost, significantly lowering the entry threshold for potential attackers.
In a controlled experiment, researchers tested 90 popular applications across multiple categories. Instead of injecting malicious code, they instructed the AI models to make neutral modifications, reassemble the APK packages, and verify whether the altered apps remained operational. The results proved concerning for the security community.
Closed commercial models successfully completed the task in 84% of attempts, while models with open weights achieved a 61% success rate. On average, the AI required 14 iterations and between five and a half to nine minutes to produce a working modified version. The final cost per successful outcome ranged from 0.88 to 40.89 rubles, depending on the model and number of attempts.
These figures imply that a determined actor could attempt to modify approximately one hundred widely used applications for only a few thousand rubles. In real-world scenarios, the same process could be used to insert data-stealing functionality, change application behavior, or establish communication with external servers controlled by attackers.
The resulting counterfeit builds are easy to promote as official updates, improved versions, or applications unavailable in the Google Play store. Distribution channels include third-party app catalogs, websites, messaging platforms, and specialized online communities. Users who regularly sideload APK files from untrusted sources are particularly exposed.
Lowering the Barrier for App Modification Attacks
Positive Technologies emphasizes that generative AI has not invented a fundamentally new attack technique. Instead, it has automated and accelerated the labor-intensive process of reverse engineering and code modification that previously demanded considerable time and specialized expertise.
Developers are advised to implement stronger code protection mechanisms against analysis and tampering, actively monitor the appearance of unofficial builds, and integrate security considerations from the earliest stages of application design. Without such measures, malicious clones may appear faster than legitimate teams can release patches.

Building Your First Home Network Lab: Essential Tools and Experiments to Understand Corporate Networks
A cybersecurity professional without network knowledge resembles a guard without a building blueprint, spotting alarms but unable to trace the intruder. Setting up a personal lab on a standard computer bridges this gap through virtualization and hands-on practice with protocols and attacks. The guide recommends GNS3 for topology emulation, VirtualBox or VMware for running Windows and Linux workstations, Cisco Packet Tracer for quick simulations, Wireshark for traffic analysis, and draw.io for diagramming. Key experiments include configuring Cisco IOS routers with IP addressing, testing default gateways, observing ARP requests and replies, triggering broadcast storms via switch loops, and enabling STP to prevent loops. The lab demonstrates how legacy protocols like ARP expose networks to spoofing and why segmentation with VLANs and firewalls matters. Resources from CyberED provide demo access to courses on SOC analysis, penetration testing, and AI applications in security to extend learning.
PSLC and Agent-Ops: From Product Support to Infrastructure Transformation
Sergey Zhitinsky, founder of Git in Sky, attended the OPS Talk by Sber meetup on October 19 and discussed the PSLC methodology with architect Alexander Shapovalov. PSLC, or Product Service Lifecycle, outlines two loops for restoring services immediately and improving reliability to prevent recurrence through teams, knowledge, and platform support. Agent-Ops focuses on eight detailed steps for individual infrastructure tasks: intention, evidence collection, diagnostics, planning, approval, controlled change, verification, and lessons learned. The article illustrates their complementary use in a scenario where post-release log growth fills a database disk, requiring both service restoration and root-cause fixes. Both approaches emphasize knowledge retention, action control, and human accountability, though Agent-Ops v0.5.1 mandates explicit human approval and separate execution for production changes. PSLC suits larger organizations with shared platforms, while Agent-Ops targets smaller teams handling infrastructure operations with AI agents.
Russian Organizations Allocate 4.5 Trillion Rubles to Innovation Spending in 2025
Large and medium-sized Russian organizations directed a total of 4.5 trillion rubles toward innovation activities during 2025. Nearly half of the expenditure originated from the services sector, while information technology and telecommunications accounted for 860.9 billion rubles. The Institute for Statistical Studies and Economics of Knowledge at HSE University published the figures based on Rosstat data, showing an innovation intensity rate of 2.7 percent. Services companies alone contributed approximately 2.3 trillion rubles, including 882.7 billion rubles for research and development. Astra Group IR Director Vladislav Anshakov outlined major spending areas such as product development, cloud and AI hardware, and acquisitions of technologies and teams. The group expanded its portfolio with the Perseus DBMS and a 26 percent stake in AI developer AIB. More than one-third of organizations cited high costs and insufficient internal funds as key barriers to further innovation.
Telegram macOS Developer Says 99.9% of Client Code Is Now Written by AI and Suggests Firing Manual Coders
Mike, the developer of the official Telegram client for macOS, stated that artificial intelligence now generates 99.9 percent of the messenger's client code. He argued that programmers who continue writing code manually should be dismissed. In a Telegram discussion, Mike cited the gram.org website as an example created entirely with AI assistance in a single day, with domain support from Pavel Durov. He also described adapting the iOS client for a foldable iPhone Duo overnight using Claude. According to Mike, even designers are now contributing to client code, and 80 to 90 percent of Telegram developers share his positive view of AI tools. When participants raised questions about code quality and security, Mike replied that AI also identifies and fixes vulnerabilities, claiming the resulting code is superior to human-written equivalents. He further announced plans to open a new GitHub repository for the macOS client source code, as the previous repository had not been updated for over a year.
